What is the surface area of a pyramid?

1 answer:

6 0

Well, to get the surface area, you do length x width x height. Multiply the side length of the base by the slant height and divide by two. Then, multiply by 4. This will give you the lateral surface area of the pyramid.

Evaluate the expression (4x^3)^2 for x=2 A.128 B.512 C.256 D. 1024

Answer:

d:) 1024

Step-by-step explanation:

Evaluate (4 x^3)^2 where x = 2:

(4 x^3)^2 = (4×2^3)^2

Multiply each exponent in 4×2^3 by 2:

4^2 (2^3)^2

Multiply exponents. (2^3)^2 = 2^(3×2):

2^(3×2)×4^2

4^2 = 16:

2^(3×2)×16

3×2 = 6:

2^6×16

2^6 = (2^3)^2 = (2×2^2)^2:

(2×2^2)^2 16

2^2 = 4:

(2×4)^2 16

2×4 = 8:

8^2×16

8^2 = 64:

64×16

write the slope-intercept form of the line that passes through the point (1,0) and is parallel to x-y=7. type your answer in the

Brilliant_brown [7]

Parallel lines have the same slope but different y intercepts.
turn x-y=7 into slope intercept form by isolating y which would be -y=-x+7
divide the equation by -1 in order to make y positive and you get y=x-7
So rewrite the equation with the same slope but this time solving for b
y=x+b
plug in your coordinates
0=1+b
subtract 1 from both sides
-1=b
so your equation would be
y=x-1
