Answer:

$50$

Step-by-step explanation:

$5x^{2} + 3y$

$x =-2\: and \:y = 10$

$5(-2)6^{2}+3(10)$

Calculate -2 to the power of 2 and get 4:-

 $5\times 4+3\times 10$

Multiply 5 and 4 get 20 :-

 $20+3\times 10$

Multiply 3 and 10 = 30:-

 $20 +30$

$=50$

Your friend borrows $100 from you and promises to pay you back $109 in 8 months. What annual percentage rate (A.P.R.) are you ch

NNADVOKAT [17]

Answer:

$12.0\%=0.12$

Step-by-step explanation:

We have been given that your friend borrows $100 from you and promises to pay you back $109 in 8 months.

We will use simple interest formula to solve our given problem.

$A=P(1+rt)$ , where,

A = Amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Convert 8 months to year:

$\frac{8}{12}\text{ year}=\frac{2}{3}\text{ year}$

$108=100(1+r*\frac{2}{3})$

$108=100+r*\frac{2}{3}\times 100$

$108-100+r*\frac{200}{3}$

$108-100=100-100+r*\frac{200}{3}$

$8=r*\frac{200}{3}$

$8\times \frac{3}{200}=r*\frac{200}{3}\times \frac{3}{200}$

$\frac{24}{200}=r$

$r=\frac{24}{200}$

$r=0.12$

Convert to percent:

$0.12\times 100\%=12\%$

Therefore, you are charging 12% APR to you friend.

Define the following sequence recursively: 96, 48, 24, 12, ....

Naddika [18.5K]

Answer:

I do not see that any of your options will work.

Step-by-step explanation:

a) and b) have a false first statement because f(1) = 96, not 12

c) would create the sequence 96, 1152, 13824

d.) would create the sequence 96, 192, 384. 768...

I believe the correct answer would be

f(1) = 96 f(n) = ½f(n-1) n ≥ 2

which could be either c) or d) if taking potential typographic errors into account. Recording a "2" or "12" where a "½" ought to be.
