The value of constant of variation "k" is

Solution:

Given that the direct variation is:

y = kx ----- eqn 1

Where "k" is the constant of variation

Given that the point is (5, 8)

To find the value of "k" , substitute (x, y) = (5, 8) in eqn 1

Thus the value of constant of variation "k" is k = 8/5 or 1.6

I hope this is correct and helps!

What is the sum of the first eight terms of a geometric series whose first term is 3 and whose common ratio is .5 ?

ser-zykov [4K]

$\bf \qquad \textit{sum of a finite geometric sequence}
\\ \quad \\
 S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad 
\begin{cases}
n=\textit{last term}\\
a_1=\textit{first term}\\
r=\textit{common ratio}
\end{cases}
\\ \quad \\
S_8=3\left( \cfrac{1-0.5^8}{1-0.5} \right)$

You borrowed $11,250 from the bank to buy a used car. You will pay the bank back in 5 years with 3.45% interest compounded annua

mihalych1998 [28]

Answer:

(D)$2079.23

Step-by-step explanation:

If I borrowed $11,250 from the bank to buy a used car. You will pay the bank back in 5 years with 3.45% interest compounded annually, then:

Principal=$11,250

Time=5 years

Rate=3.45%

Since it is compounded annually, our compound interest will be derived using this formula:

Interest=Amount at the end of 5 years - Principal

where:

Amount, $A=P(1+r)^n$

$=11250(1+0.0345)^5\\=11250(1.0345)^5\\=13329.23$

Therefore our Interest=13329.23-11250 =$2079.23
