Since the interest is compounded quarterly, and there are 4 quarters per year, that would leave us with 32 quarters total where interest is acquired. Now, we need to find the interest rate, that would be required in order to end up with 420 dollars after 32 quarters.

We can setup a formula using our period of time and the money he invested into the bank:

$340(x)^{32}=420$

We can divide 340 from both sides, and simplify the right side to 21 divided by 17:

$x^{32}=\frac{21}{17}$

Taking the 32th root of 21/17 is equal to 1.00662, which is equal to 100.0662%. To the nearest tenth of a percent, this is equal to 100.7%.

B) y = 3 = 2х<br><br> Is this relation linear or non-linear? Explain why.

Alika [10]

Answer:

I think you meant: y=3+2x, in that case, this is a linear answer

Step-by-step explanation:

Non- linear would look like this: K=2/3

Linear would look like this: Y=4x+7

Why:

It all comes to what is proportional and what is not.

Hoped this helped!
