Find f(-2) if f(x) = x + x + 7. f(-2) =
Lynna [10]

Answer:

f(-2) = 9

Step-by-step explanation:

Given that,

f(x) = x² + x + 7

We need to find the value of f(-2).

Put x = -2 in the given function.

f(-2) = (-2)² + (-2) + 7

= 4-2+7

= 9

Hence, the value of f(-2) is equal to 9.

Answer:

B_2=4\pi r^2

see the explanation

Step-by-step explanation:

we know that

The area of the base of a cylinder is given by the formula

B=\pi r^{2}

where

r is the radius of the circular base

If the radius is doubled

then

r=2r

The new base area is

B_2=\pi (2r)^{2}

B_2=4\pi r^2

so

B_2=4B

therefore

The new area of the base is 4 times the area of the original base

Where does the line through (1, 0, 1) and (4, −3, 3) intersect the plane x + y + z = 6?
Irina-Kira [14]

Parametrically for real t the line is


(x,y,z) = (1-t)(1,0,1) + t(4,-3,3)


(x,y,z) = (1,0,1) + t(4-1,-3-0,3-1)


(x,y,z) = (1,0,1) + t(3,-3,2)


That's three equations; we substitute into


x+y+z=6


(1+3t)+(0-3t) + ( 1+2t)=6


2t=4


t=2


(x,y,z) = (1,0,1) + 2(3,-3,2) = (7,-6,5)


The intersection is a single point (7,-6,5).
