The average rate of change of the function between the points is -4/7

The constant average rates of change of a function is also regarded as the slope or the gradient of the function

Here, we have the points to be

(-3, 16) and (4, 12)

The average rates of change between these points is calculated as

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

So, we have

Average rate of change = [12 - 16]/[4 + 3]

Evaluate the sum and the difference

So, we have

Average rate of change = -4/7

Hence, the average rate of change between the points is -4/7

The solved logarithmic function is log (2x + y) = 4 log (2) and log (4x - y) = 0 for 2x + y = 2⁴ and 4x - y = 1 respectively.

What is a logarithmic and exponential function?

Logarithmic functions and exponential functions are inverses of each other. The logarithmic function is denoted by using the word log while exponential by using the alphabet,  e. For example log 10 = 1 and e^2.

Solving the given expressions: 2x + y = 16 and 4x - y = 1

Applying given properties of logarithmic and exponential function;

log a + log b = log (ab)

4 log x = log x⁴

e^(log x) = 1

e^(x + y) = (e^x) × (e^y)

Take the expression, 2x + y = 16

Applying log on both sides, we get,

log (2x + y) = log (16)

log (2x + y) = log (2⁴)

log (2x + y) = 4 log (2)

To Check Results,

Taking exponential on both sides,

e^[log (2x + y)] = e^(4 log 2)

2x + y = e^(log 2⁴)

2x + y = 2⁴

2x + y = 16

Thus, the answer is verified.

Take expression, 4x - y = 1

Applying log on both sides, we get,

log (4x - y) = log 1

log (4x - y) = 0

To Check Results,

Taking exponential on both sides,

e^[log (4x - y)] = e^0

4x - y = 1

Thus, the answer is verified.

Hence, the solved expression is log (2x + y) = 4 log (2) and log (4x - y) = 0 for 2x + y = 2⁴ and 4x - y = 1 respectively.

The length of the rectangle is 45 yard and the width of the rectangle is 9 yard.

WE have Given that the length of a rectangle is 5 times its width, and the perimeter is 108 yd.

Let the width of rectangle be 'x' yard and the length of the rectangle is '5x' yd . also the length is five times the width.

we know that,

The Perimeter of the rectangle = 2(length + width)

The perimeter of rectangle is 108 yd.

Therefore the perimeter = 2( 5x + x )

                              108    = 2( 6x )

                              108    = 12x

The factored form of the cubic equation x³ + 27 is equal to (x + 3) · (x - 3 / 2 - i 3√3 / 2) · (x - 3 / 2 + i 3√3 / 2). The roots of the cubic equation are - 3, 3 / 2 + i 3√3 / 2 and 3 / 2 - i 3√3 / 2.

In this problem we find a cubic equation of the form x³ + a³, whose factor form can be found by using algebra properties:

f(x) = x³ + 27

f(x) = (x + 3) · (x² - 3 · x + 9)

A number line is a  vertical or horizontal line that has endpoints and it is used to represent numbers at a constant interval

The fraction is given as

-3/8

The above number is a negative number and it is greater than -1

This means that the location of the number line is between 0 and -1

To plot the number line, we make use of 8 intervals between 0 and -1 ( as represented by the number lines in the options)

The third point to the left of 0 represents -3/8

The function is f (x) = 3/4 x - 1.

What is Linear equation?

A linear equation is an algebraic equation with slope m is defined as,

y = mx + b

Where, b is the y - intercept.

Given that;

Slope of function (m) = 3/4

f (-12) = -10

Now,

A linear equation with slope m is defined as,

f (x) = mx + b

Substitute m = 3/4,

f (x) = 3/4 x + b

Apply the condition f (-12) = -10 we get,

f (-12) = 3/4 * (-12) + b

- 10 = 3 * (-3) + b

- 10 = - 9 + b

b = - 10 + 9

b = - 1

Substitute value of m and b in linear equation we get;

The function is,

⇒ f (x) = 3/4 x - 1.

Hence, The function is f (x) = 3/4 x - 1.

Applying the definition of supplementary angles, the measure of angle A is: 47°

The definition of supplementary angles states that two angles are referred to as supplementary angles if they give a sum of 180 degrees when added together.

Given that angle A and angle B are supplementary angles, therefore, based on the definition of supplementary angles, measure of angle A + measure of angle B = 180 degrees.

Measure of angle A = 3x - 10

Measure of angle B = 8x - 19

Substitute

3x - 10 + 8x - 19 = 180

Combine like terms

11x - 29 = 180

11x = 180 + 29

11x = 209

11x/11 = 209/11

x = 19

Measure of angle A = 3x - 10

Plug in the value of x

Measure of angle A = 3(19) - 10

Measure of angle A = 57 - 10

Measure of angle A = 47°

The cost of one packet of biscuit is £1.60.

The total amount that Aisha paid for the items she purchased is a function of the total cost of bread rolls, ketchup and biscuits.

Total cost of the items purchased = total cost of bread rolls + total cost of biscuits + total cost of ketchup

Total cost of bread rolls = cost per packet x number of packets bought

2 x £1.20 = £2.40

Total cost of ketchup = cost of one bottle x number of bottles bought

1 x £2.10 = £2.10

Total cost of biscuits = cost of one packet  x number of packets bought

3 x b = 3b

Total cost = £2.40 + £2.10 + 3b = £4.50 + 3b

Total amount paid by Aisha = note given - change received

£10 - 70p

£10 - £0.70 = £9.30

Total amount paid by Aisha =  total cost

£9.30 = £4.50 + 3b

£9.30 - £4.50 = 3b

£4.80 = 3b
