What principal would you need to invest at a rate of 4% to earn $500 in 6 months? Round your answer to the nearest cent.

Answers

Answer 1

From the information available, we have the following;

Rate = 4% (0.04)

Time = 0.5 (half a year/6 months)

Interest = 500

Principal = ???

Therefore, we would substitute these into the simple interest formula as shown below;

[tex]\begin{gathered} I=P\times R\times T \\ \text{Make P the ubject of the equation;} \\ \text{Divide both sides by R x T and you'll have;} \\ \frac{I}{R\times T}=\frac{P\times R\times T}{R\times T} \\ \frac{I}{R\times T}=P \\ \frac{500}{0.04\times0.5}=P \\ \frac{500}{0.02}=P \\ P=25000 \end{gathered}[/tex]

ANSWER:

The principal to be invested therefore is $25,000

The quadratic equations solved using the square root property is;

a. x = -3 and 7

b. x = 3 and -11

How to solve the quadratic equations

Given the quadratic equation as;

(x -2)² - 11 = 14

To determine the roots, we have to take the following steps;

expand the bracket

(x-2)(x-2) - 11 = 14

x² -2x -2x + 4 - 11 =1 4

collect like terms

x² - 2x - 2x + 4 -11 - 14 = 0

Add or subtract like terms

x² - 4x - 21 = 0

Factorize the equation

x² - 7x + 3x - 21 = 0

factorize further

x(x - 7) + 3(x - 7) = 0

Then. x = - 3, x = 7

x² + 8x + 16 = 49

collect like terms

x² + 8x + 16 - 49 = 0

x² + 8x - 33 = 0

Factorize further

x² + 11x - 3x - 33 = 0

x( x + 11) - 3(x + 11) = 0

Then, x = 3 and x = -11

Hence, the values are -3 and 7 and 3 and -11 respectively.

The simplified mixed number upon evaluation is [tex]3\frac{11}{27}[/tex].

What is a mixed number?Mixed numbers, also known as mixed fractions, are made up of a whole number and a proper fraction (a fraction whose numerator is less than its denominator). There are a few features that mixed numbers and decimals have in common. A decimal number is made up of a whole number and a fractional element separated by a decimal point. A mixed number is made up of a whole number and a proper fraction, but they are not separated by a decimal point.

Given:

a = −3/5 and b = −6.75

We have to determine the value of (2a−1/3) ÷ b/15.

Substituting the values of a and b in the expression, we get

(2(−3/5)−1/3) ÷ (−6.75)/15

⇒ (-6/5 - 1/3) ÷ (-0.45)

⇒ (-23/15) ÷ (-0.45)

6. Which ordered pair is a solution to this system of equations below ? *7х + 5y = 59Зх — 9y = 159О(( -17, -12)О (-17, 12)О(17, -12)(17,12)

Answers

Answer:

(17, -12)

Explanation:

The system of equations is

7x +5y = 59

3x - 9y = 159

An ordered pair satisfies the system if it satisfies both equations. So, for each option we need to replace the ordered pair on the given equations.

For (x, y) = (-17, -12)

7x +5y = 59

7(-17) + 5(-12) = 59

-119 - 60 = 59

-179 = 59

The equality is not satisfied, so (-17, -12) is not a solution to this system

For (x, y) = (-17, 12)

7x +5y = 59

7(-17) + 5(12) = 59

-119 + 60 = 59

-59 = 59

The equality is not satisfied, so (-17, 12) is not a solution to this system

For (x, y) = (17, -12)

7x +5y = 59

7(17) + 5(-12) = 59

119 - 60 = 59

59 = 59

3x - 9y = 159

3(17) - 9(-12) = 159

51 + 108 = 159

159 = 159

Since both equations are satisfied, so (17, -12) is a solution to the system of equations

Therefore, the answer is (17, -12)

The answer has the form Select an answer Where A = and B =

Answers

SOLUTION

From the question, we want to find

(a) The domain of the function.

The domain is gotten from the x-values. Looking at the x-values from the graph whether the curve is expanded or not, it would satisfy infinitely the value of any x-values. That is whatever x-value will make the function defined.

So the domain is all real numbers or negative infinity to positive infinity Written as

[tex]\begin{gathered} (A,B) \\ where\text{ } \\ A=-\infty\text{ and B = }\infty \end{gathered}[/tex]

(b) The range is the y-values that satisfy the function. Looking at the curve, the y-values would have infinitely number of negative values, but does not exceed 1, which is the maximum value.

So the range is negative infinity to 1.

Written as

[tex]\begin{gathered} (A,B] \\ where\text{ } \\ A=-\infty\text{ and B = 1} \end{gathered}[/tex]

(c) The function is increasing from infinite negative values of x, up to where x is -3, before it starts decreasing of sloping downwards

Hence the function is increasing between negative infinity to negative 3, written as

[tex]\begin{gathered} (A,B) \\ where\text{ } \\ A=-\infty\text{ and B = -3} \end{gathered}[/tex]

(d) Interval where f(x) >= 0

For f(x), that is y to be greater than or equal to zero, this must take place at the x-intercept, that is where the graph cuts the x-axis plane. Looking at the graph, this is at -4 and -2

hence the answer is between -4 and -2, written as

[tex]\begin{gathered} [A,B] \\ where\text{ } \\ A=-4\text{ and B = -2} \end{gathered}[/tex]

Elsa, Chau, and Felipe served a total of 100 orders Monday at the school cafeteria. Chau served 3 times as many orders as Felipe. Felipe served 5 more orders than Elsa. How many orders did they each serve?

Answers

Answer:

Chau served 63 orders.

Elsa served 16 orders.

Felipe served 21 orders.

Step-by-step explanation:

Given information:

Elsa, Chau, and Felipe served a total of 100 orders.Chau served 3 times as many orders as Felipe. Felipe served 5 more orders than Elsa.

Define the variables:

Let e = number of ordered Elsa served.Let c = number of ordered Chau served.Let f = number of ordered Felipe served.

Create a system of equations from the given information and defined variables:

[tex]\begin{cases}e+c+f=100\\c=3f\\e=f-5\end{cases}[/tex]

Substitute the second and third equations into the first equation and solve for f:

[tex]\implies e+c+f=100[/tex]

[tex]\implies (f-5)+3f+f=100[/tex]

[tex]\implies 5f-5=100[/tex]

[tex]\implies 5f=105[/tex]

[tex]\implies f=21[/tex]

Substitute the found value of f into the second equation and solve for c:

[tex]\implies c=3f[/tex]

[tex]\implies c=3(21)[/tex]

[tex]\implies c=63[/tex]

Substitute the found value of f into the third equation and solve for e:

[tex]\implies e=f-5[/tex]

[tex]\implies e=21-5[/tex]

[tex]\implies e=16[/tex]

Therefore:

Chau served 63 orders.Elsa served 16 orders.Felipe served 21 orders.

Let us assume that,

→ Elsa = x

→ Felipe = x + 5

→ Chau = 3x + 15

Now the required value of x,

→ x + x + 5 + 3x + 15 = 100

→ 5x + 20 = 100

→ 5x = 100 - 20

→ x = 80/5

→ [ x = 16 ]

Then the orders each serve is,

→ Elsa = x = 16

→ Felipe = x + 5 = 16 + 5 = 21

→ Chau = 3x + 15 = 48 + 15 = 63

Hence, the above one is correct.

An angle is a symbol in Euclidean space made up of two arcs that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of 2 dimensions ultimately creates angles. We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves. Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius. The arc is centered when there is a geometric angle.

[tex]\begin{gathered} k=\frac{y}{x} \\ k=-\frac{5}{100} \\ k=-0.05 \end{gathered}[/tex]

This means that fo every passing second the depth increases -0.05, we can establis the relationship as:

[tex]y=-0.05x[/tex]

Now using this expression we can calculate the missing values of time and depth

For depth y= -1m

[tex]\begin{gathered} -1=-0.05x \\ x=-\frac{1}{-0.05} \\ x=20s \end{gathered}[/tex]

For time x=60s

[tex]\begin{gathered} y=-0.05\cdot60 \\ y=-3m \end{gathered}[/tex]

For time x=240s

[tex]\begin{gathered} y=-0.05\cdot240 \\ y=-12m \end{gathered}[/tex]

Which are the intercept points and vertex point for the function ƒ(x) = x^2 + 5x + 6?

Answers

Answer:

The intercept points are:

[tex]\begin{gathered} (-3,0) \\ (-2,0) \end{gathered}[/tex]

The vertex is:

[tex](-\frac{5}{2},-\frac{1}{4})[/tex]

Step-by-step explanation:

To find the intercept points, we equal the function to zero and solve for x, as following:

[tex]\begin{gathered} x^2+5x+6=0 \\ \rightarrow(x+3)(x+2)=0 \\ \\ \rightarrow x+3=0\Rightarrow x_1=-3 \\ \\ \rightarrow x+2=0\Rightarrow x_2=-2 \end{gathered}[/tex]

Now, we know that the intercept points have an x-value of -3 and -2. Since we're talking about intercepts, the y-values will be 0.

Therefore, we can conlcude that the intercept points are:

[tex]\begin{gathered} (-3,0) \\ (-2,0) \end{gathered}[/tex]

The vertex of any given quadratic function in the form:

[tex]f(x)=ax^2+bx+c[/tex]

is:

[tex](-\frac{b}{2a},f(-\frac{b}{2a}))[/tex]

This way, for the given function, we'll have that the vertex point is:

[tex](-\frac{5}{2},-\frac{1}{4})[/tex]

What is the inverse of the function h(x) = 3 over 4 x+12

Answers

To answer this question we will set the equation y=f(x), then we will solve the equation for x, and finally, we will exchange x and y.

Setting y=f(x) we get:

[tex]y=\frac{3}{4}x+12.[/tex]

Subtracting 12 from the above equation we get:

[tex]\begin{gathered} y-12=\frac{3}{4}x+12-12, \\ y-12=\frac{3}{4}x\text{.} \end{gathered}[/tex]

Multiplying the above equation by 4/3 we get:

[tex]\begin{gathered} (y-12)\times\frac{4}{3}=\frac{3}{4}x\times\frac{4}{3}, \\ x=\frac{4}{3}y-16. \end{gathered}[/tex]

Exchanging x and y in the above equation we get:

[tex]y=\frac{4}{3}x-16.[/tex]

Therefore the inverse function of h(x) is:

[tex]h^{-1}(x)=\frac{4}{3}x-16.[/tex]

Answer:

[tex]h^{-1}(x)=\frac{4}{3}x-16.[/tex]
