The function y = 7 / 8 ( 18 ) ˣ is an exponential growth function.

An exponential function is defined as y = a ˣ where x is a variable, and a is a constant called the base of the function.

We are given a function:

y = 7 / 8 ( 18 ) ˣ

We need to tell whether is is a exponential growth or decay function.

We can see that the value of a ˣ = (18) ˣ

So, the value of a = 18.

Since, it is an integer and not a fraction, its value will increase with the increase in exponent x.

So, it will be a exponential growth function.

Therefore, we get that, the function y = 7 / 8 ( 18 ) ˣ is an exponential growth function.

y  = -x +2 an equation in slope-intercept form of the line that bisects the angle.

What exactly does slope intercept mean?

Given:

Angled formed by ray BA and ray BC is 90 degrees.

To find:

The equation of line that bisects the angle formed by ray BA and ray BC.

If a line bisects the angle formed by ray BA and ray BC, then it must be passes through point B and makes angles of 45 degrees with ray BA and ray BC.

It is possible if the line passes though point B(-1,3) and other point (-2,4).

Equation of line is

y - y₁  = y₂ - y₁/x₂ - x₁  ( x - x₁)

y - 3 = 4 - 3 / - 2 - ( -1)  ( x - ( -1)

y - 3 = 1/-1 ( x + 1 )

y - 3 = -x -1

Add 3 on both sides

y = -x -1 + 3

y  = -x +2

A function that gives the length of the hypotenuse of an isosceles right triangle with side length s is given by h(s)=s√2 and the length of the side of the triangle is approximately 4.24 inches.

The hypotenuse of a right angled triangle is defined as the longest side of the triangle. The hypotenuse is also located opposite the right angle.

From the Pythagorean Theorem we know that for a right angled triangle, the sum of the square of the legs of the triangle is equal to the square of the hypotenuse.

Given legs of the right triangle is s. Let us consider a function h(s) for the hypotenuse.

Therefore we can define the function h(s) as

h(s)=s√2

The inverse of the function can be written as

y=s√2

or, s=y²/2

Hence the inverse function is:

h⁻¹(s)=s²/2

Now for hypotenuse = 6 inches.

Each side can be calculated using the inverse function h⁻¹(s)=s²/2.

s=6÷√2

or, s=4.242...

Hence the length of the side of the triangle is approximately 4.24 inches.

The sum of all decent fractions with a denominator of 20 is 4.

Thus, option (d) is correct.

To find the sum of all decent fractions whose denominator is equal to 20, consider fractions with numerators that are coprime to 20 (i.e., the numerator and 20 have no common factors other than 1).

The decent fractions with a denominator of 20 can be written as:

1/20, 3/20, 7/20, 9/20, 11/20, 13/20, 17/20, and 19/20.

To find the sum, add up these fractions:

Sum = 1/20 + 3/20 + 7/20 + 9/20 + 11/20 + 13/20 + 17/20 + 19/20

Sum = (1 + 3 + 7 + 9 + 11 + 13 + 17 + 19) / 20

Sum = 80 / 20

Sum = 4

Therefore, the sum of all decent fractions with a denominator of 20 is 4.

Thus, option (d) is correct.

The radius of a circle is determined as  27.95 units.

Now the formula for the arc length when the central angle is given in the degrees;

arc length  = (θ/360°)×(2πr)

Where, r is the radius of the circle and π = 3.14.

Write the formula for r;

r = (arc length/2π)×(360°/θ)

For the given values in question;

arc length = 82 central angle = 135 degrees.

r = (82/2×3.14)×(360°/135°)

r = (13.05)×(2.67)

r = 27.95

The linear function that contains the points (0,3) and (-1,5) is given by:

y = -2x + 3.

The graph is not given and I couldn't find the problem on a search engine, hence I am going to suppose that two points on the graph are (0,3) and (-1,5).

You can select the value of y when the function crosses the y-axes(y-intercept) and another point and follow the same procedure I am going to do here.

A linear function is modeled in slope-intercept form by:

y = mx + b

In which:

For this problem, we have that when x = 0, y = 3, hence the slope is of b = 3. When x = -1, y = 5, hence the slope(change in y divided by change in x) is given by:

(3 - 5)/(0 - (-1)) = -2.

Hence the function is:

y = -2x + 3.

The required simplification of rational expression is 3(x + 5) / (x + 3).

What is a rational number?

Any real number that can be represented in the form of p/q, where q is not equal to 0 is called a rational number. The decimal expansion of rational numbers is terminating and repeating.

Simplifying the rational expression:  x² + 3x - 10 / x² + 4x - 12 . 3x + 18 / x + 3

Given a rational expression,

x² + 3x - 10 / x² + 4x - 12 . 3x + 18 / x + 3

On simplifying, we get,

(x² + 3x - 10).(3x + 18) / (x² + 4x - 12).(x + 3)

For numerator, (x² + 3x - 10).(3x + 18), we have,

= 3(x + 5)(x - 2)(x + 6)

For denominator,  (x² + 4x - 12).(x + 3)

= (x + 6)(x - 2)(x + 3)

Now, (x² + 3x - 10).(3x + 18) / (x² + 4x - 12).(x + 3) = 3(x + 5)(x - 2)(x + 6) / (x + 6)(x - 2)(x + 3)

= 3(x + 5) / (x + 3)

The restrictionto the given rational expression is that the denominator,  x + 3 should not be 0.

Hence, the required simplification of rational expression is 3(x + 5) / (x + 3).

a. Han wrote (1/2, 0) as x-intercept of the line instead of (2, 0).

b. The x-intercept: (2, 0)

The y-intercept: (0, 5)

The y-intercept of a line is the corresponding value of y when the value of x is equal to zero.

On the other hand, the x-intercept of a line is the corresponding value of x when the value of y is equal to zero.

Y-intercept is (0, b), while x-intercept is (b, 0), where b is the value of the point on the axis that is being intercepted.

In slope-intercept form, y = mx + b or y = b + mx, the y-intercept is represented as b, which is (0, b).

Given the equation in slope-intercept form as y = 5 - 10/4x, the y-intercept, b = 5. Therefore, is expressed as (0, 5).

To find the x-intercept, substitute y = 0 into y = 5 - 10/4x:

0 = 5 - 10/4x

Solve for x

-5 = -10/4x

-20 = -10x

-20/-10 = x

x = 2

The x-intercept is (2, 0), while the y-intercept is (0, 5).

Therefore:

a. The Han got the x-intercept wrong, it should be (2, 0), not (1/2, 0).

b. The x-intercept is (2, 0), while the y-intercept is (0, 5).

The factors of given equation are -3/4 and -2.

Rewriting the equation -

4x² + 11x + 6 = 0

The factors for the given expression will be calculated based on two factors -

1. The sum of factors should be equal to sum of numeral value of b (11 in this case)

2. The product of factors should be equal to product of numeral values of a and c (24 in this case)

As per the above rules, the appropriate factors should be 8 and 3.

Rewriting the given equation with possible factors -

4x² + 8x + 3x + 6 = 0

Taking common values

4x(x + 2) +3(x + 2) = 0

(x + 2) (4x + 3) = 0

x = -3/4, -2

Thus, the factors of given expression are -3/4 and -2.

To check the correctness of factors, we will keep each value of x in equation.

When x = -3/4

4x² + 11x + 6 = 0

4(-3/4) + 11(-3/4) + 6 = 0

9/4 -33/4 + 6 = 0

9/4 = 2.25 and 33/4 = 8.25

2.25 - 8.25 + 6 = 0

-6 + 6 = 0

0 = 0

When x = -2

4x² + 11x + 6 = 0

4(-2)² + 11(-2) + 6 = 0

16 - 22 + 6 = 0

22 - 22 = 0

0 = 0

Since both values of x give 0 on both sides of equation, the factors of equation are correct.
