Answer:

c = - 20

Step-by-step explanation:

Given

- 21 = \frac{1}{2} c - 11 ( add 11 to both sides )

- 10 = \frac{1}{2} c ( multiply both sides by 2 to clear the fraction )

- 20 = c , that is

c = - 20

A rectangular prism has a volume of 16y^4+16^y^3+48y^2 cubic units. Which could be the base area and height of the prism?
Liula [17]
\bf \textit{volume of a rectangular prism}\\\\&#10;V=Bh~~&#10;\begin{cases}&#10;B=area~of\\&#10;\qquad its~base\\&#10;h=height\\&#10;-----------\\&#10;V=16y^4+16y^3+48y^2&#10;\end{cases}&#10;\\\\\\&#10;16y^4+16y^3+48y^2=Bh\implies 16y^2(y^2+y+3)=Bh

so since its just two factors, you can pick either for the "B" or "h", or one can say that the trinomial is the "B", because it can be factored into a couple more binomials, either way will work.

what is the sum of the first five ferms of a geometric series with a1=10 and r=1/5? express your answer as an important fraction
mote1985 [20]
The sum of any geometric sequence, (technically any finite set is a sequence, series are infinite) can be expressed as:

s(n)=a(1-r^n)/(1-r), a=initial term, r=common ratio, n=term number

Here you are given a=10 and r=1/5 so your equation is:

s(n)=10(1-(1/5)^n)/(1-1/5)  let's simplify this a bit:

s(n)=10(1-(1/5)^n)/(4/5)

s(n)=12.5(1-(1/5)^n) so the sum of the first 5 terms is:

s(5)=12.5(1-(1/5)^5)

s(5)=12.496

as an improper fraction:

(125/10)(3124/3125)

390500/31240

1775/142
