The function g(x) is a transformation of the quadratic parent function, f(x) =
x2. What function is g(x)?

a. g(x) = 1/2x^2
b. g(x) = -2x^2
c. g(x) = 2x^2
d. g(x) = -1/2x^2

Answers

The answer is D) g(x) -1/2x^2

The function g(x) is a transformation (flipped upside down and horizontally stretched) of the quadratic parent function, f(x) = x2. g(x) = -0.5x².

What is flipping upside down?

Flipping upside down, is found by taking the negative of the original function; that is, the rule for this transformation is −f (x).

Since, g(x) is an upside down function of f(x), g(x) = -f(x).

What is stretching a graph?

If we multiply a function by a coefficient, the graph of the function will be stretched.

A function h(x) represents a horizontal compression of f(x) if h(x) = f(cx) and c > 1.

A function h(x) represents a horizontal stretch of f(x) if h(x) = f(cx) and 0 < c < 1.

Since, g(x) is clearly a stretched transformation of f(x), c < 1.

The possible function g(x) = -0.5x².

The volume of this cone is 540π. Work out the height,h, of the cone, radius=9cm

Answers

Answer:

h = 20

Step-by-step explanation:

540π = 1/3 . h . π . 9^2

get rid of π

540 = 1/3 . h . 9^2

multiply by 3 to get rid of 1/3

3 . 540 = h . 9^2

1620 = h . 81

divide by 81

1620/81 = h

20 = h

An auto shop charges a customer an equal amount for each new tire purchased plus an additional fee for an oil change.
The function C(t) = 87t +32 represents the total cost, C, of getting an oil change and purchasing t, tires.
What does the number 87 represent in the function?
A The slope and the cost per tire purchased.
B The slope and the fee for an oil change.
The y-intercept and the cost per tire purchased.
The y-intercept and the fee for an oil change.

Answers

The cost per unit of the auto shop function is the slope of the function

87 represents the slope and the cost per tire purchased

The function is given as:

[tex]\mathbf{C(t) = 87t + 32}[/tex]

A linear function is represented as:

[tex]\mathbf{C(t) = mt + b}[/tex]

Where:

m represents the slope or the unit rate.

So, by comparison:

[tex]\mathbf{m = 87}[/tex]

This means that 87 represents the slope and the cost per tire purchased

4.704=y+310

Enter your answer as a decimal in the box

Answers

Answer:

-305.296

Step-by-step explanation:

Make y the subject of the equation.

If 4.704=y+310 is the given equation, the value y is -305.3

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is 4.704=y+310

Four point seven zero four equal to y plus three hundred ten

We need to solve for y in the given equation.

4.704=y+310

Subtract 310 on both sides

4.704-310=y+310-310

-305.3=y

Hence, y is -305.3 for the equation 4.704=y+310

find x if the base angles of an isosceles triangle are 47 degrees and 3x+14

Answers

Answer:

Step-by-step explanation:

The value of x is 11.

Given,

The base angles of an isosceles triangle are 47 degrees and 3x+14 degrees.

We need to find x.

What is an isosceles triangle?

An isosceles triangle is a triangle that has two equal sides and two equal angles.

The equal angles are the base angles.

Find x.

We have,

Base angles: 47 degrees and (3x + 14) degrees

Since base angles are equal in an isosceles triangle.

We have,

47 = 3x + 14

47 - 14 = 3x

33 = 3x

x = 33/3 = 11

x = 11

Thus the value of x is 11.

Which equation represents a line parallel to 3x − 8y = 12?

Answers

Answer: I don’t know the choices, but a line parallel to that equation must have a slope of 3/8 when simplified into slope-intercept form.

Slope-intercept form: y = mx + b

Solving:
3x - 8y = 12
-8y = -3x + 12
y = 3/8x - 1 1/2

The equation that is parallel to 3x − 8y = 12 is y = (3/8)x - 4 so option (A) is correct.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given equation,

3x − 8y = 12

3x - 12 = 8y

y = (3/8)x - 12/8

By comparing y = mx + c

Slope m = 3/8

The parallel lines have the same slope thus y = (3/8)x - 4 will have the same slope of 3/8 so it will be parallel.

Hence "The equation that is parallel to 3x − 8y = 12 is y = (3/8)x - 4".
