You should add 25 because you should always add the square of the p value (which is equal to half of the b value, which makes the p value 5).
Basically, the p value should be half of b and the square root of c.

You deposit $650 in a savings account. How long does it take an account with an annual interest rate of 5% to earn $178.25 in in
laiz [17]

Answer:

It takes an account 5.4 years  to earn $178.25 in interest with an annual interest rate of 5%.

Step-by-step explanation:

You can use the following formula to calculate the time it takes an account to earn a certain amount in interest:

t=(1/r)*((F/P)-1), where:

t= time

r= rate of interest= 5%

F= future value= 650+178.25=828.25

P= present value= 650

Now, you can replace the values on the formula:

t=(1/0.05)*((828.25/650)-1)

t=20*0.27

t=5.4

According to this, the answer is that it takes an account 5.4 years  to earn $178.25 in interest with an annual interest rate of 5%.

PLEASE PLEASE HELP!!!!
Usimov [2.4K]

Answer:

B

Step-by-step explanation:

\cos( \alpha )  +  i\sin( \alpha )  =  {e}^{i (\alpha   + 2\pi)}

z = 3(cos π/2 + i sin π/2) =→

3 {e}^{i \frac{\pi}{2} }

z⁷ =

{3}^{7}  {e}^{i \frac{7\pi}{2} }  =   {3}^{7}  {e}^{i \frac{(7 - 4)\pi}{2} }  =  {3}^{7}  {e}^{i \frac{3\pi}{2} }  =  {3}^{7} ( \cos( \frac{3\pi}{2} )  + i \sin( \frac{3\pi}{2} ) ) = 2187( \cos( \frac{3\pi}{2} )  + i \sin( \frac{3\pi}{2} ) )

Printing a newsletter costs $1.50 per copy plus $450 in printer's fees. The copies are sold for $3 each.How many copies of the n
alekssr [168]

Answer:

300 Copies

Step-by-step explanation:

Break even Units = Fixed Costs / (Price - Variable Cost)

Fixed Costs = $450

Variable Cost = 1.5

Price = 3

Break Even Units = 450 / (3 - 1.5)

Break Even Units = 450 / 1.5

Break Even Units = 300

300 Copies must be sold to break even.

I hope this helps!
