Step-by-step explanation:

Plug in 5 as x

h(5) = 25 - 2

h(5) = 23

So, h(5) = 23

THE SUM 10 INFINITY OF A GEOMETRIC SERIES IS 100. FIND THE TERM IF THE COMMON FIRST RATIO IS - 1/2​
zhuklara [117]

Answer:

a = 150

Step-by-step explanation:

<u>Sum to infinity of a geometric series</u>

S_{\infty}=\dfrac{a}{1-r}\:\textsf{ for }|r| < 1

where:

  • a is the first term
  • r is the common ratio

Given:

  • S_{\infty}=100
  • r=-\dfrac{1}{2}

Substitute the given values into the formula and solve for a:

\begin{aligned}S_{\infty} & =\dfrac{a}{1-r}\\\\\implies 100 & =\dfrac{a}{1-\left(-\frac{1}{2}\right)}\\\\ 100 & =\dfrac{a}{1+\frac{1}{2}}\\\\100 & = \dfrac{a}{\frac{3}{2}}\\\\a & = \dfrac{3}{2} \cdot 100\\\\a & = 150\end{aligned}
