Writing polynomial function given a y-intercept

answer:

a = 28x^2

step-by-step explanation:

the area of a triangle is equal to

a = 1/2 b*h

the base is 7x and the height is 8x

a = 1/2 (7x)*(8x)

a = 1/2 (56x^2)

a = 28x^2

answer:

step-by-step explanation:

answer:

1.

step-by-step explanation:

note that 2^4 - 2^3 = 16 - 8 = 8 = 2^3

in a similar way 2^6 - 2^5 = 64 - 32 = 32 = 2^5.

so 2^99 - 2^98 = 2^98 ,   2^98 - 2^97 = 2^97 ,   2^97 - 2^96 = 2^96 and so on.

therefore when we come to the last 2 terms we have 2^1 - 2^0 = 2 - 1

= 1 , so the answer is 1.
