C

28

= π

The diameter is equal to twice the radius.

C = 2πr

C = 2(14)π

C = 28π

Answer and explanation:

Given : The radius of a circle is 14.

To find : Which equation expresses the ratio of the circumference of the circle to the circle's diameter?

Solution :

The circumference of the circle is C=2\pi r

Radius is r=14

The circumference of the circle is C=2\pi\times 14=28 \pi

The circle's diameter is d=2r

The ratio of the circumference of the circle to the circle's diameter is given by,

C:d=2\pi r : 2r

C:d=\pi : 1

Therefore, option B is correct.

For what value of x will the function f(x) = -3(x - 10)(x - 4) have a maximum value? Find the maximum value.
gayaneshka [121]

Hello!

To find the maximum value of the function f(x) = -3(x - 10)(x - 4), the easiest way is to find the vertex using the formula: x = -b/2a.

Firstly, we need to simplify f(x).

f(x) = -3(x - 10)(x - 4)

f(x) = -3(x² - 14x + 40)

f(x) = -3x² + 42x + -120

Since the equation f(x) is now simplified to standard form, we can find the vertex.

a = -3, b = 42, and c = -120

x = -(42)/2(-3) = -42/-6 = 7

Then, we substitute 7 into the the function f(x) = -3(x - 10)(x - 4), or

f(x) = -3x² + 42x + -120, to find the y-value of the vertex.

f(x) = -3(7 - 10)(7 - 4)

f(x) = -3(-3)(4)

f(x) = 27

The vertex of f(x) is (7, 27).

Therefore, the maximum x-value for the function f(x) is 7.
