The solution of the equation is B. 4

Step-by-step explanation:

√x + 2 = x

√x = x - 2

(√x)² = (x-2)²

x = (x-2) (x-2)

x = x² - 4x + 4

x moves to the right

0 = x² - 4x - x + 4

0 = x² - 5x + 4

0 = (x-1) and (x-4)

x-1 = 0 x-4 = 0

x = 1 (not) x = 4

So, the solution to the equation is B. 4

Step-by-step explanation:

Because Angle GJH is 90 degrees, Angle HJZ is also 90 degrees. (Because all right angles are 90 degrees)

Now, find Angle WJZ

90 - 18 = 72 degrees

By the Vertical Angles Theorem, Angle GJL is congruent to Angle ZJW

Now solve for x

72 = 9x

x = 8

Answer:

Step-by-step explanation:

Let's call the smallest of the three consecutive even integers "x". Since they are consecutive and even, we know that the next two integers must be "x + 2" and "x + 4".

Now we can set up the equation for the problem:

4 * (x + (x + 2) + (x + 4)) = 240 + 6x

Expanding the parentheses on the left side:

4 * (3x + 6) = 240 + 6x

Simplifying the left side:

12x + 24 = 240 + 6x

Subtracting 6x from both sides:

6x + 24 = 240

Subtracting 24 from both sides:

6x = 216

Dividing both sides by 6:

x = 36

So the smallest of the three consecutive even integers is 36, and the others are 38 and 40.

The combination should be 20 of Brand A and 20 of Brand B.

When a linear function is exposed to various constraints, it is maximised or reduced using the mathematical modelling technique known as linear programming. In commercial planning, industrial engineering, and—to a lesser extent—the social and physical sciences, this method has proven helpful for directing quantitative decisions.

Answer:

The solution to the equation 20 = m ÷ -5 is m = -100

To see this, we can multiply both sides of the equation by -5 to isolate the variable m:

20 × -5 = m ÷ -5 × -5

Expanding the right side of the equation:

20 × -5 = m × 1

Combining like terms:

-100 = m

And the solution is:

m = -100

Verification:

To verify the solution, we can plug in the value of m back into the original equation and see if it is true:

20 = -100 ÷ -5

Expanding -100 ÷ -5:

20 = 20

Since 20 = 20 is a true statement, we have verified that the solution m = -100 is correct.

Answer:

P = 72.5 * e^(0.025t)

Step-by-step explanation:

Here's a step by step solution with all the details and calculus involved.

(a) Express P as a function in the form P = Poat.

Since the population is growing continuously at a rate of 2.5% per year, we can use the formula for continuous growth:

P = Po * e^(rt)

where Po is the initial population (72.5 million), r is the continuous growth rate (0.025), and t is the time elapsed in years since 2004.

The continuous growth rate, r, is related to the annual growth rate, g, by:

r = g / 100

So, the continuous growth rate is 0.025.

Substituting the values into the formula for continuous growth, we get:

P = 72.5 * e^(0.025t)

This is the expression for the population as a function of time in the form P = Poat.

(b) Express P as an exponential function using base e.

The exponential function using base e is already in the desired form. So, we can simply write:

P = 72.5 * e^(0.025t)

The 5th , 6th and 7th term of the arithmetic sequence is 1 , 13/16 and 10/16 respectively

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the first term of the AP be a₁ = 1 3/4

Let the second term of the AP be a₂ = 1 9/16

So , the common difference of AP d = a₂ - a₁

On simplifying the equation , we get

The common difference d = 1 9/16 - 1 3/4 = ( 25/16 - 7/4 )

The common difference d = - ( 3/16 )

And , the nth term of the AP is a + (n - 1) d

So , the 5th term of the AP = ( 1 3/4 ) + ( 4 ) ( -3/16 )

On simplifying the equation , we get

The 5th term of the AP = ( 7/4 ) + ( -3/4 )

The 5th term of the AP = 4/4 = 1

Therefore , the value of A = 1

And , the 6th term of the AP = ( 1 3/4 ) + ( 5 ) ( -3/16 )

On simplifying the equation , we get

The 6th term of the AP = ( 7/4 ) + ( -15/16 )

The 6th term of the AP = 13/16

Therefore , the value of B = 13/16

And , the 7th term of the AP = ( 1 3/4 ) + ( 6 ) ( -3/16 )

On simplifying the equation , we get

The 7th term of the AP = ( 7/4 ) + ( -18/16 )

The 7th term of the AP = 10/16

Therefore , the value of C = 10/16

Hence , the arithmetic progression is solved

Answer:

The number of points needed to redeem the voucher is 92.5

Step-by-step explanation:

Let x be the total number of points needed to redeem the voucher.

Amelia has [tex]\frac{3}{5}[/tex] × x points,before she earns the another 50 points,

After she earns another 50 points,

Now

she has [tex]\frac{3}{5}[/tex] × x + 50 points.

she still needs [tex]\frac{3}{10}[/tex] × x  points to redeem the voucher.

Now

From above we get a equation,

[tex]\frac{3}{5}[/tex] × x + 50 = [tex]\frac{9}{10}[/tex] × x

Solving the equation we can get x,

[tex]\frac{3}{5}[/tex] × x  = [tex]\frac{9}{10}[/tex] × x - 50

if we multiply both sides by 5/3, we get,

x = (9/10 × x - 50) × 5/3

After expanding the right side,

x = (9/10 × x - 50) × 5/3

x = (9x/10 - 250/3)

Now,

Subtracting 9x/10 from both sides,

0 = 250/3 - 9x/10

If we add 9x/10 to both sides,

9x/10 = 250/3

Again,

If we multiply both sides by 10/9,

x = 250/3× 10/9

x = 250 × 10 / (3 × 9)

x = 250 × 10 / 27

x = 250 × 10 / 27

x = 250 × 10 / 27

x = 250 × 10 / 27

  = 250 × .37

x = 92.5

The equation of the straight line is 2x+5y=340.

The x-intercept point of that line is (170,0).

A straight line has different forms like point-slope form, standard form, slope-intercept form, and others. A specific form is used according to the given data for convenience.

As f(-10)=64 and f(15)=54, two points can be wriiten as (x₁,y₁)=(-10,64) and (x₂,y₂)=(15,54).

Now, use the two-point form of the equation of a line.

(y-y₁)/(x-x₁)=(y₂-y₁)/(x₂-x₁)

(y-64)/(x-(-10))=(54-64)/(15-(-10))

(y-64)/(x-10)=-10/25

25(y-64)=-10(x-10)

5(y-64)=-2(x-10)

5y-320=-2x+20

2x+5y=340

Therefore, the required equation of the line is 2x+5y=340.

To find the x-intercept, substitute y=0 into the equation of the line.

What is the slope of a line?

A line's slope in mathematics is defined as the ratio of the change in the y coordinates to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are represented by y and x, respectively.

Consequently, the formula for the change in the y-coordinate with respect to the change in the x-coordinate is

m = y/x = y/x = change in y/change in x

where "m" represents a line's slope.

Additionally, the slope of the line can be depicted by

tan θ = Δy/Δx

So, the slope of a line is tan.

Answer:

Step-by-step explanation:

We can start by finding how much money Carlos spent on clothes. To do this, we simply multiply the original amount of $400 by 40%:

Clothes = $400 * 40% = $400 * 0.40 = $160

Next, we find how much money Carlos has left after spending on clothes. To do this, we subtract the amount spent on clothes from the original amount:

Remaining Money = $400 - $160 = $240

Finally, we find how much money Carlos spent on video games. To do this, we multiply the remaining money by 50%:

Video Games = $240 * 50% = $240 * 0.50 = $120

So, in total, Carlos spent $160 on clothes and $120 on video games, for a total of $160 + $120 = $280.

And Carlos has $400 - $280 = $120 left.

After spending 40% of the $400 on clothes, Carlos has $400 x (100 - 40) / 100 = $240 left.

Next, he spent 50% of the remaining $240 on video games, which is $240 x 50 / 100 = $120.

Therefore, Carlos spent a total of $400 - $240 = $160.

Finally, Carlos has $240 - $120 = $120 left.

The points on the line of the graph are;

The slope of the graph as x tends to 2⁺ is therefore;

Slope = (3 - 1)/(3 - 1) = 1

The equation of the line is therefore;

[tex]\lim \limits_{x\to 2^+} \frac{f(x) -4}{f(x + 3)} = \frac{x - 4}{x + 3} | x = 2[/tex]

The piecewise function for the interval, x → 3⁻ is; f(x) = x, therefore;
