The definition of a rate of change is a rate that expresses how one quantity changes in relation to another quantity. When d(t)=2t is stated, the average speed from t=5 to t=9 is 28 feet or 2 feet per second.

A rate of change is a rate that describes how one quantity changes in relation to another quantity.

d(t)=2t² is given, we need to find the average speed in feet per second from t=5 to t=9.

d(t)=2t².

The average rate of change is calculated by the formula:

d(t₂) - d(t₁) / t₂ - t₁

So plug in 5 as t₁ and 9 as t₂.

=> d(9) - d(5) / 9 - 5

=> (2×81) - (2×25) / 9 - 5

=> 162 - 50 / 4

=> 112 / 4 = 28

Therefore the average speed is 28 feet.

Let x represent the number of pages Aiden read on day one.

On day two he read twice the number of pages, so 2x represents the number of pages he read on day two.

On the third day, he read 6 pages less than what he read on the first day, so x - 6 represents the number of pages he read on day three.

The total number of pages he read in three days is the sum of the pages he read on each day:

x + 2x + (x - 6) = 458

3x - 6 = 458

3x = 464

x = 154

Aiden read 154 pages on day one.

The function that represents the point (x, y) being reflected across the y-axis is F(x, y) = F(-x, y)

A point (x, y) can be reflected across the y-axis by multiplying the x-coordinate by -1.

This is because the y-axis is a vertical line running through the center of a coordinate plane, and reflecting a point across this line means reversing its position along the horizontal (x) axis.

So, to reflect a point (x, y) across the y-axis, the function can be represented as:

f(x, y) = (-x, y)

This function takes in the coordinates (x, y) of a point and returns the new coordinates (-x, y) after reflecting it across the y-axis.

15b is also a no because that is 15 times the price of the bill.

b + 0.15b is a yes because you are adding the bill and 15% of the bill as a tip.

1.15b is a no because you are multiplying the bill by 1.15.

1.015 is a no because you're multiplying the bill by 1.015.

b + (15/100)b is a yes because you are adding the bill and 15% out of 100% of the bill as a tip.

b + 0.15 is a no because you would be tipping them 15 cents, not 15% of the bill.

Answer: To calculate the final value of an investment with compound interest, you can use the formula:

A = P(1 + r/n)^(nt)

where:

A = final amount

P = initial investment (principal)

r = annual interest rate (expressed as a decimal)

n = number of times interest is compounded per year

t = number of years the investment is held

In this case, we have:

P = 170000

r = 0.04 (4% expressed as a decimal)

n = 2 (semiannually)

t = 7

So plugging these values into the formula:

A = 170000(1 + 0.04/2)^(2*7)

A = 170000(1.02)^14

A = 170000(1.286816)

A = 217,912.72

The final value of the investment after 7 years is 217,912.72 baht.

Please note that this is a simple interest calculation, and in real world some other factors like taxes, fees, etc should be taken into account.

Answer:

To multiply using fraction form, we can convert the decimal numbers to fractions and then multiply them together.

4.4 can be written as 44/10

3.2 can be written as 32/10

So the multiplication would be:

(44/10) * (32/10) = (4432)/(1010) = 1408/100

To simplify this fraction, we can divide the numerator and denominator by their greatest common factor which is 4, we get:

1408/100 = 352/25

So the product of 4.4 and 3.2 is 352/25 in fraction form.

Answer: Justin is 9 years old, Peyton is 6 years old and Matt is 24 years old

When Δ BCF is congruent to Δ BDE, then the value of x is obtained as 10.

What is congruence?

In mathematics, the term "congruent" refers to figures and shapes that can be flipped or rearranged to match up with other ones. These forms can be mirrored to produce related shapes.

It is given that Δ BCF ~ Δ BDE.

Since the triangles are congruent so, it can be written that -

BC/BD = BF/BE

Substituting the values in the equation -

52/(52 + 39) = 56/[(56) + (5x-8)]

Simplifying the equation -

52/91 = 56/[(56) + (5x-8)]

4/7 = 56/(48+5x)

4(48+5x) = 56 × 7

192 + 20x = 392

20x = 392 - 192

20x = 200

x = 200/20

x = 10

Therefore, the value of x is obtained as 10.

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

x−y=−2,4x−y=4

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

x−y=−2

Add y to both sides of the equation.

x=y−2

Substitute y−2 for x in the other equation, 4x−y=4.

4(y−2)−y=4

Multiply 4 times y−2.

4y−8−y=4

Add 4y to −y.

3y−8=4

Add 8 to both sides of the equation.

3y=12

Divide both sides by 3.

y=4

Substitute 4 for y in x=y−2. Because the resulting equation contains only one variable, you can solve for x directly.

x=4−2

Net change of a function is the difference of the output values corresponding to two input values.

Consider the function y = f(x).

Net change from a point x = a to x = b is,

Net change = f(b) - f(a)

Average rate of change of a function from x = a to x = b is,

Average rate of change = [f(b) - f(a)] / [b - a]

The points are (0, 5) and (5, 4).

Here, the value of x on the indicated points are x = 0 and x = 5.

The value of y are f(0) = 5 and f(5) = 4.

Net change = f(5) - f(0) = 4 - 5 = -1

Average rate of change = [f(5) - f(0)] / [5 - 0] = (4 - 5) / 5 = -1/5
