A clock face has a diameter of 10 inches. What is the area of the clock face?
sleet_krkn [62]

Answer:

A = 78.5 in ^2

Step-by-step explanation:

Area of a circle = pi * r^2

The radius is d/2

r= 10/2

r =5

A = pi * r^2

Substitute r=5

A = pi *(5)^2

A = 25 pi

We know that pi is approximated by 3.14

A = 25 (3.14)

A = 78.5 in ^2

For the functions f(x) = 2x + 2 and g(x) = 7x + 1, which composition produces the greatest output? a) Both compositions produce
Usimov [2.4K]
So subsitue and try so
f(g(x))=2(7x+1)+2
g(f(x))=7(2x+2)+1

multiply them out
f(g(x))=2(7x+1)+2=14x+2+2=14x+4
g(f(x))=7(2x+2)+1=14x+14+1=14x+15
14x+15>14x+4
therefor
g(f(x))>f(g(x))

the answer is D g(f(x)) produces the greatest output

What is the solution for the equation 6x - 8 = 4x? x =
GarryVolchara [31]

Answer:

x = 4

Step-by-step explanation:

6x - 8 = 4x

<em>subtract 4x from both sides of the equation</em>

6x - 4x -8 = 4x - 4x

2x - 8 = 0

<em>add 8 to both sides of the equation</em>

2x - 8 + 8 = 0 + 8

2x = 8

<em>divide both sides of the equation by 2</em>

2x/2 = 8/2

x = 4
