Answer:

2.512

Step-by-step explanation:

the equation for circumference of a circle is

2(pi)r

plug in the 4

2(pi)4

combine like terms

8(pi)

you can leave the answer as is or you can multiply

8(3.14)= 2.512

the answer would be 2.512

***pi is equal to 3.14, if you are not allowed to keep your answer in terms of pi there is a pi button on the calculator you can use, or simply plug in 3.14

Identify the zeros of f(x)=(x-7)(x+4)(3x-2)
alexgriva [62]

To find the zero you must set each factor equal to zero and solve for for x like so...

Factor (x - 7)

x - 7 = 0

x = 7

Factor (x + 4)

x + 4 = 0

x = -4

Factor (3x - 2)

3x - 2 = 0

3x = 2

x = \frac{2}{3}

All the zeros are:

-4, \frac{2}{3}, 7

Hope this helped!

20 POINTS!!!
choli [55]

Hello from MrBillDoesMath!

Answer:

x = 0, 7

Discussion:

f(g(x)) =

f ( x^2-7x) =

1/ ( x^2 - 7x)


The points NOT in the domain are those where the denominator,  x^2 - 7x = 0.

x^2 - 7x   = 0       =>       factor x from each term

x(x-7) = 0            =>        one or both terms must each 0

x = 0 or x =7


Thank you,

MrB
