How do the graphs of y =1/x and y = 3/x – 4 compare?
Pie
The graphs of y =1/x and y = 3/x – 4 can be compared by saying that c<span>ompared to the graph of y =1/x , the graph of y =3/x – 4 is a vertical stretch by a factor of 3 and a translation of 4 units down. This can be seen clearly when you graph the functions on a x-y coordinate plane.</span>

Jay places $3200 in an investment account earning 4.1% interest compounded weekly. How much money would he have in the account a
jasenka [17]

Answer:

A = $3,926.71

Step-by-step explanation:

Given: Principal (P) = $3200, Annual Rate (R) = 4.1%, Time = 5 years

To find: How much money would he have in the account after 5 years, if he made no deposits or withdrawals during that time?

Formula: A = P(1 + r/n)^nt

Solution: Compound interest is one of the most important concepts to understand when managing your finances. It can help you earn a higher return on your savings and investments, but it can also work against you when you're paying interest on a loan

First, convert R as a percent to r as a decimal

r = R/100

r = 4.1/100

r = 0.041 rate per year,

Then solve the equation for A

A = P(1 + r/n)^{nt}

A = 3,200.00(1 + 0.041/12)^{(12)(5)}

A = 3,200.00(1 + 0.003416667)^{(60)}

A = $3,926.71

Hence, Jay would have $3,926.71 after 5 years is if he made no deposits or withdrawals during that time.

Your friend asks you to help him study and will pay you 5
algol [13]

Answer:

My payment for the 7th study session will be 78125 dimes.

Step-by-step explanation:

My friend will pay me 5 dimes for helping him study for the first time.

Now, I agree to help him if he multiplies my payment by 5 for each study session.

So, he will pay 25 dimes for the 2nd study session, 125 dimes for the 3rd study session and so on.

Hence, my payment in each study session increases in geometric progression as follows:

5, 25, 125, ........ so on.

So, the 7th term of this series indicates the number of dimes that my friend pays me after the 7th study session.

This is a G.P. series having first term 5 and common ratio 5, then the 7th term will be 5\times 5^{(7 - 1)} = 5^{7} = 78125

Therefore, my payment for the 7th study session will be 78125 dimes. (Answer)
