Determine the roots of each of the following quadratic equations using the factorisation method (b) x^2-10+16=0
(e) 2x^2+3x-9=0
(h) x^-5x=0

Answers

Roots of a quadratic equation using the factorisation method, we need to find two numbers that multiply to the constant term of the equation and add up to the coefficient of the linear term. Then, we can use these two numbers to factor the quadratic expression and solve for the roots.

a) For the quadratic equation x^2 - 10x + 16 = 0, we need to find two numbers that multiply to 16 and add up to -10. These numbers are -2 and -8, so we can write the quadratic as (x - 2)(x - 8) = 0. Setting each factor equal to zero, we get x - 2 = 0 and x - 8 = 0, which give us the roots x = 2 and x = 8.

b) For the quadratic equation 2x^2 + 3x - 9 = 0, we need to find two numbers that multiply to -18 (since 2*(-9) = -18) and add up to 3. These numbers are 6 and -3, so we can write the quadratic as 2x^2 + 6x - 9x - 9 = 0. Factoring by grouping, we get 2x(x + 3) - 9(x + 3) = 0, which simplifies to (2x - 9)(x + 3) = 0. Setting each factor equal to zero, we get 2x - 9 = 0 and x + 3 = 0, which give us the roots x = 9/2 and x = -3.

c) For the quadratic equation x^2 - 5x = 0, we can factor out an x to get x(x - 5) = 0. Setting each factor equal to zero, we get x = 0 and x - 5 = 0, which give us the roots x = 0 and x = 5.

Question 3 Not yet answered Find the inverse of the following function 8+5x f(x) = x+3 Marked out of 1.0 Flag question f(x)-1 = =

The inverse of f(x) is: [tex]f^{-1(x)}[/tex] = (x - 8)/5 switched the variables, so instead of [tex]f^{-1(x)}[/tex] , we wrote it as [tex]f^{-1(x)}[/tex] .

What is function?

In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range.

To find the inverse of the function f(x) = 8 + 5x, we need to solve for x in terms of f(x).

Let y = f(x) = 8 + 5x

To find the inverse, we need to isolate x on one side of the equation:

y = 8 + 5x

y - 8 = 5x

x = (y - 8)/5

Therefore, the inverse of f(x) is:

[tex]f^{-1(x)}[/tex] = (x - 8)/5

Or, we can write it as:

[tex]f(x)^{-1}[/tex] = (x - 8)/5

Note that we switched the variables, so instead of [tex]f^{-1}[/tex] , we wrote it as [tex]f^{-1(x)}[/tex] .

Answers

The function graphed on the axes above should be expressed as a piecewise function as follows;

f(x) = -3x - 8    {x ≤ -2}

    = 6x - 17     {x > 3}

How to determine the piecewise function?

In order to determine the piecewise function, we would determine an equation that represent each of line shown on the graph. Therefore, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (4 + 2)/(-4 + 2)

Slope (m) = 6/-2

Slope (m) = -3.

At data point (-2, -2) and a slope of -3, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y + 2 = -3(x + 2)  

y = -3x - 8

For the second line, we have:

Slope (m) = (7 - 1)/(4 - 3)

Slope (m) = 6/1

Slope (m) = 6.

At data point (3, 1) and a slope of 6, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 1 = 6(x - 3)  

y = 6x - 17

The continuous-time convolution integral of y(t) is [tex]$y(t) = k e^{-yt} u(t) * (u(t+2)-u(t))$[/tex].

To evaluate this convolution integral, we first need to express the integrand as a piecewise function. Since u(t) is 1 for t >= 0 and 0 for t < 0, we can rewrite u(t+2)-u(t) as a piecewise function:

u(t+2)-u(t) =

Calculate the real return of your stock investment using the following information:


Purchase price of 100 shares of stock

Selling price of 100 shares of stock

10% tax rate

3% inflation rate

2% administrative fee on the selling price of the stock

1. I imagine buying 100 shares of Amazon.com Inc. on January 3, 2020, when the stock price was $93.75, investing $9,375.  

Today, October 31, 2022, the stock price of Amazon.com Inc. is $102.44.

2. The real return on my investment in Amazon.com Inc was a net loss of  7.12% or $667.60.

3. The company I selected to buy its stock three years ago was Amazon.com Inc.

4. I decided on Amazon.com Inc., hoping to earn spectacular returns since it is a multinational technology company.

5. When I consider the actual return on the stock investment in Amazon.com Inc., I think it was an unwise investment.

6. The investment returned a negative real value because I realized less than I initially invested; I actually lost about $667.60 overall.

What is the stock investment?

Stock investment is the purchase of shares for an ownership interest in a publicly-listed company.

The investor makes the investment with the hope that the investee will grow and perform well over some period, enabling the investor to earn some real returns (in the form of dividends and capital appreciation).

Purchase of 100 shares Jan. 3, 2020 = $9,375 (100 x $93.75)

Sales of 100 shares Oct. 31, 2022 = $10,244 (100 x $102.44)

Tax (10%) = $1,024.40 ($10,244 x 10%)

Inflation (3%) = $307.32 ($10,244 x 3%)

Administration fee on sales (2%) = $204.88 ($10,244 x 2%)

Real Returns in dollars = $8,707.40 ($10,244 - $1,024.40 - $307.32 - $204.88)

Loss on returns = $667.60 ($8,707.40 - $9,375)

Loss percentage = 7.12% ($667.60/$9,375 x 100)

Unfortunately, Amazon.com Inc. did not pay any dividends during the period of my investment, and I really lost funds to taxes, inflation, and administration fees when I sold it.

If the string makes 44 degree angle with the ground, and the holder is 90 feet from the base of the tree, how tall is the tree, rounded to the nearest whole foot.

show all work

Answers

Answer:

87 feet.

Step-by-step explanation:

To solve the problem, we can use the tangent function, which relates the opposite side of a right triangle (the height of the tree in this case) to the adjacent side (the horizontal distance from the base of the tree to the point directly below the kite) through the angle between them (44 degrees):

tan(44) = height / distance

We know the angle and the distance (90 feet), so we can solve for the height:

height = distance * tan(44)

height = 90 * tan(44)

The value of tan(44) is approximately 0.9656887, which means that if we multiply it by 90, we get:

90 * tan(44) = 90 * 0.9656887

Using a calculator, we get:

90 * 0.9656887 = 86.908983

However, this is not the final answer, because we were asked to round to the nearest whole foot. Since 86.908983 is closer to 87 than to 86, we round up to 87. Therefore, the approximate height of the tree is 87 feet.

Answers

The left-hand limit and the right-hand limit both do not exist, the limit of sin(1/x) as x approaches 0 does not exist.

(i) To show that the limit of (1/x^2) as x approaches 0 does not exist, we need to show that the limit from the left-hand side and the right-hand side are not equal or they both go to infinity. Let's consider the right-hand limit:

lim x→0+ (1/x^2) = +∞ (the limit goes to infinity)

Now let's consider the left-hand limit:

lim x→0- (1/x^2) = +∞ (the limit goes to infinity)

Since the left-hand limit and the right-hand limit are both infinite and not equal, the limit does not exist.

(ii) To show that the limit of (1/√x^2) as x approaches 0 does not exist, we need to show that the limit from the left-hand side and the right-hand side are not equal or one or both of them goes to infinity. Let's consider the right-hand limit:

lim x→0+ (1/√x^2) = lim x→0+ (1/|x|) = +∞ (the limit goes to infinity)

Now let's consider the left-hand limit:

lim x→0- (1/√x^2) = lim x→0- (1/|x|) = -∞ (the limit goes to negative infinity)

Since the left-hand limit and the right-hand limit are not equal, the limit does not exist.

(iii) To show that the limit of (x+(x)) as x approaches 0 does not exist, we need to show that the limit from the left-hand side and the right-hand side are not equal or one or both of them goes to infinity. Let's consider the right-hand limit:

lim x→0+ (x+(x)) = 0+0 = 0

Now let's consider the left-hand limit:

lim x→0- (x+(x)) = 0+0 = 0

Since the left-hand limit and the right-hand limit are equal, the limit exists and equals 0.

(iv) To show that the limit of sin(1/x) as x approaches 0 does not exist, we need to show that the limit from the left-hand side and the right-hand side are not equal or one or both of them goes to infinity. Let's consider the right-hand limit:

lim x→0+ sin(1/x) does not exist

This is because sin(1/x) oscillates infinitely many times between -1 and 1 as x approaches 0 from the right-hand side, and the limit does not approach any single value.

Now let's consider the left-hand limit:

lim x→0- sin(1/x) does not exist

This is because sin(1/x) oscillates infinitely many times between -1 and 1 as x approaches 0 from the left-hand side, and the limit does not approach any single value.

my = population mean = 606 megabytes per month

b. The standard deviation (standard error) of the sample mean can be calculated using the formula:
standard error = [tex]\frac{standard deviation}{\sqrt{sample size} }[/tex]
standard error = [tex]\frac{240}{\sqrt{64} }[/tex]
standard error = 30

Therefore, the standard error of the sample mean is 30 megabytes per month.

c. To find the probability that the average amount of data used in this sample was greater than 632 megabytes, we need to use the formula for the z-score:

Find the maximum distance between the point (1, 3) and a point on the circle of radius 4 centered at the origin. Hint: the maximizing distance should be at least 4 and the function has critical points every increment of pi.

Answers

To find the maximum distance between the point (1,3) and a point on the circle of radius 4 centered at the origin, we can use the distance formula. Let (x,y) be a point on the circle, then the distance between (1,3) and (x,y) is given by:

d = √((x-1)^2 + (y-3)^2)

Since the point (x,y) lies on the circle of radius 4 centered at the origin, we have:

x^2 + y^2 = 16

We can solve for y in terms of x:

y = ±√(16 - x^2)

Substituting into the distance formula, we get:

d = √((x-1)^2 + (±√(16 - x^2) - 3)^2)

Simplifying and squaring, we get:

d^2 = (x-1)^2 + (±√(16 - x^2) - 3)^2

d^2 = x^2 - 2x + 1 + (16 - x^2 - 6√(16 - x^2) + 9)  (or d^2 = x^2 - 2x + 1 + (16 - x^2 + 6√(16 - x^2) + 9))

d^2 = -x^2 - 2x + 26 ± 6√(16 - x^2)

To maximize the distance, we want to maximize d^2. Note that the maximizing distance should be at least 4, which means that we only need to consider the positive root of d^2. The critical points of d^2 occur when the derivative is zero, so we differentiate with respect to x:

d(d^2)/dx = -2x - 2(±3x/√(16 - x^2))

Setting this equal to zero, we get:

x = ±4/√5, ±2√2/√5, 0

Note that x = 0 corresponds to the point (0,4) on the circle, which has distance 5 from (1,3), so it is not a critical point. The other critical points correspond to the points where the circle intersects the x-axis and the y-axis. Evaluating d^2 at these critical points, we get:

d^2 = 18 ± 6√6

The maximum distance is therefore √(18 + 6√6), which occurs when x = ±4/√5.

3. Isaac paid $119. 70 for a racket, a bag and a pair of shoes. A pair of shoes cost three times as much as a bag. The racket cost twice as much as the bag. How much did Isaac pay for the racket?​

Answers

Isaac pay for the cost of racket is 39.9.

The cost of a pair of shoes is three times the cost of a bag, so we can write:

Cost of shoes = 3b

Similarly, the cost of the racket is twice the cost of the bag, so we can write:

Cost of racket = 2b

Now we can use the given information to set up an equation:

Cost of racket + Cost of bag + Cost of shoes = $119.70

Substituting the expressions we found above, we get:

2b + b + 3b = $119.70

Simplifying the equation:

6b = $119.70

Dividing both sides by 6:

b = $19.95

So the cost of the bag is $19.95.

We can use this to find the costs of the shoes and racket:

Cost of shoes = 3b = 3($19.95) = $59.85

Cost of racket = 2b = 2($19.95) = $39.90

Therefore, Isaac paid $39.90 for the racket.

Suppose y=f(x) is continuous for all real numbers. Use the sign chart for the first derivative to answer the question that follows: f'() 0 +++ 0 1 Determine which of the following best describes what must be true about absolute extrema on the interval [0,00) There is an absolute maximum at x-1 There is an absolute minimum at x--1 There is an absolute maximum at x=-1 There is an absolute minimum at x 1

Answers

Based on the provided information, f'(x) changes from positive to negative at x=1, indicating that the function has a local maximum at this point.

Since y=f(x) is continuous for all real numbers and the interval is [0, ∞), there is an absolute maximum at x=1. The best description of the absolute extrema is: "There is an absolute maximum at x=1." Based on the sign chart for the first derivative, we know that the function is increasing from negative infinity to x=-1, and then decreasing from x=-1 to positive infinity. This means that there is an absolute maximum at x=-1 since the function is increasing to that point and decreasing after it. Therefore, the correct statement is: "There is an absolute maximum at x=-1."

Days 1-3: $200 (initial balance)
Days 4-20: $300 ($100 purchase)
Days 21-30: $150 ($150 payment)
What is the finance charge, on the average daily
balance, for this card over this 1 month period?
finance charge = $ [?]
Round to the nearest hundredth.

Answers

Based on the average daily balance, the finance charge for this credit card that charges 10.5% APR is $2.10.

What is the finance charge?

The finance charge consists of the interest and other fees that lenders charge borrowers.

One of the methods for computing the finance charge is the average daily balance, which takes the sum of the daily balances and divides by the number of days in the billing cycle.

APR interest rate = 10.5%

Monthly period days = 30

Days 1-3: $200 (initial balance)        3 days      $600 ($200 x 3)

Days 4-20: $300 ($100 purchase)  17 days   $5,100 ($300 x 17)

Days 21-30: $150 ($150 payment)  10 days   $1,500 ($150 x 10)

Total balances = $7,200

Average daily balance = $240 ($7,200 ÷ 30)

Finance charge = $2.10 ($240 x 10.5% x 30/360)

In the month of January, Sasha had a balance of $3200 on her credit card. She made a payment of $300 and left the remaining balance to be paid later. How much interest will she pay this month if her APR is 18.75%? Round to the nearest cent.

A.) $35.10
B.) $46.19
C.) $4.50
D.) $543.75

Answers

Rounding to the nearest cent, Sasha will pay $35.10 in interest this month. Therefore, the correct answer is option A.

To calculate the interest that Sasha will pay, we need to use the following formula:

Interest = (Balance * APR * Days in a billing cycle) / 365

where Balance is the amount owed after the payment, APR is the annual percentage rate, and Days in the billing cycle are the number of days in the billing cycle.

Since we do not know the number of days in the billing cycle, we will assume it to be 30 days for simplicity. Therefore, the balance owed after the payment is:

Balance = $3200 - $300 = $2900

Substituting the values into the formula, we get:

Interest = ($2900 * 0.1875 * 30) / 365

= $35.09

A quadratic equation has zeros at -6 and 2. Find standard form

Answers

The quadratic equation with zeros at -6 and 2 is y² + 4y - 12 = 0. This is in standard form, which is ax² + bx + c = 0, with a = 1, b = 4, and c = -12.

To find the quadratic equation with zeros at -6 and 2, we can start by using the fact that if a quadratic equation has roots x₁ and x₂, then it can be written in the form

(y - x₁)(y - x₂) = 0

where y is the variable in the quadratic equation.

Substituting the given values of the zeros, we get

(y - (-6))(y - 2) = 0

Simplifying this expression, we get

(y + 6)(y - 2) = 0

Expanding this expression, we get

y² - 2y + 6y - 12 = 0

Simplifying this expression further, we get

y² + 4y - 12 = 0

So the quadratic equation with zeros at -6 and 2 is

y² + 4y - 12 = 0

This is the standard form of a quadratic equation, which is

ax² + bx + c = 0

where a, b, and c are constants. In this case, a = 1, b = 4, and c = -12.

god filled his gas tanker with 19/5/9 tank of gas if he uses 1 5/6 gallons of gas each day after how many days will he need to refill his tank

Answers

It will take God approximately 32 days to use up all the gas in his tanker and need a refill.

If God filled his gas tanker with 19/5/9 tank of gas and uses 1 5/6 gallons of gas each day, we can calculate how many days it will take for him to need a refill.

First, we need to convert the mixed number 19/5/9 to an improper fraction:

19/5/9 = (19 * 9 + 5) / 9 = 176/9

So God has 176/9 tanks of gas in his tanker.

Next, we can calculate how much gas God uses each day:

1 5/6 = (6 * 1 + 5) / 6 = 11/6

So God uses 11/6 gallons of gas each day.

To find out how many days it will take for God to need a refill, we can divide the amount of gas in his tanker by the amount of gas he uses each day:

(176/9) / (11/6) = (176/9) * (6/11) = 32

Therefore, it will take God approximately 32 days to use up all the gas in his tanker and need a refill.

Approximate the following integral using the Composite Simpson Rule with n=4, find a bound for the error using error formula and compare this to the actual error: ∫10.5x4 dx.

Answers

The actual error is:
|4194 - 4787.9476| = 593.9476
Since the bound for the error is 0.371, which is much smaller than the actual error of 593.9476, we can say that the Composite Simpson Rule with n=4 provides a very good approximation to the integral.

Sure! We can approximate the integral ∫10.5x4 dx using the Composite Simpson Rule with n=4.

First, let's split the interval [1,4] into 4 subintervals of equal width:

h = (4-1)/4 = 0.75

x0 = 1, x1 = 1.75, x2 = 2.5, x3 = 3.25, x4 = 4

Next, we need to evaluate the function at the endpoints and midpoints of each subinterval:

f(x0) = f(1) = 10.5(1)^4 = 10.5
f(x1) = f(1.75) = 10.5(1.75)^4 = 100.2842
f(x2) = f(2.5) = 10.5(2.5)^4 = 528.125
f(x3) = f(3.25) = 10.5(3.25)^4 = 1841.7969
f(x4) = f(4) = 10.5(4)^4 = 3360

Now, we can apply the Composite Simpson Rule formula:

∫10.5x4 dx ≈ h/3 [f(x0) + 4f(x1) + 2f(x2) + 4f(x3) + f(x4)]

≈ 0.75/3 [10.5 + 4(100.2842) + 2(528.125) + 4(1841.7969) + 3360]

≈ 4787.9476

To find a bound for the error using the error formula, we can use the following formula:

|E| ≤ K*h^4*(b-a)/180

where K is a constant, h is the width of each subinterval, and (b-a) is the length of the interval.

Since f''''(x) = 840, we can use K = 840.

|E| ≤ 840*(0.75)^4*(4-1)/180

≈ 0.371

To compare this to the actual error, we can find the exact value of the integral using the antiderivative:

∫10.5x4 dx = 10.5(1/5)x^5 + C

evaluated from x=1 to x=4:

= 10.5(1/5)(4^5 - 1^5)

= 4194

The actual error is:

|4194 - 4787.9476| = 593.9476

Since the bound for the error is 0.371, which is much smaller than the actual error of 593.9476, we can say that the Composite Simpson Rule with n=4 provides a very good approximation to the integral.

find the center and radius of:
x^2+y^2+2x+6y=26

Answers

Answer:

center = -1, -3

radius = 6

Step-by-step explanation:

x² + y² + 2x + 6y = 26

x² + 2x + y² +6y = 26

equation of a circle is,

(x - h)² + (y - k)² = r²

where center of a circle is (h,k)

radius = r

x² + 2x + y² + 6y = 26

finding the middle point for mid term breaking of the equations,

(2/2)² = 1

(6/2)² = 9

x² + 2x + 1 + y² + 6y + 9 = 26 + 1 +9

to balance the equation we have to add the midpoints at both sides,

thus we have equation of a circle,

(x + 1)² + (y + 3)² = 36

so,

centre of a circle = -1, -3

radius = 6

What is vertex?

The vertex, in geometry, is the intersection of two or more lines, curves, or edges. It can also refer to the vertex of a parabola, which is where a function reaches its highest or lowest value.

We can see here that the equation of the hyperbola is seen in standard form. It is known that the center of the hyperbola is at (h, k) is (2, 1).

The distance between the center and vertices = a

where a² = coefficient of the positive term

So we see that  a² = 16

a = 4.

Also, the distance between the center and co-vertices = b

where b² = 4

b = 2.

Thus,

Vertex 1 = (2 + 4, 1) = (6, 1)
