Using the intermediate value theorem F(x)=x^4-4x^2-9; a=4 , b=5

A.Because​ f(x) is a polynomial with ​f(​1)

nothing0 and ​f(5​)

nothing​0, the function has a real zero between and .

B.

Because​ f(x) is a polynomial with ​f(1​)

nothing0 and ​f(5​)

nothing​0, the function has a real zero between and .

C.

Because​ f(x) is a polynomial with ​f(1​)

nothing0 and ​f(​5)

nothing​0, the function has a real zero between and .

D.

Because​ f(x) is a polynomial with ​f(1​)

nothing0 and ​f(5​)

nothing​0, the function has a real zero between and .

Step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
