The answer for the first one is
$22 \leqslant r$
You have to add both sides by 14 and you will get my answer.

I'm sorry I don't know the answer for the second one.

Hope this helps though!

Use the compound interest formulas A = P 1 + r n nt and A = Pe rt to solve. 2) Suppose that you have $8000 to invest. Which inve

Gnoma [55]

Answer: A

Compound interest simply defined as the interest added at regular interval. Compound interested can be calculated using

Compound interest = P (1+) ^nt and Pe ^rt

P = Initial balance

r = Annual interest rate

n = Number of times the interest is compounded per year

t =Number of year money is invested

Using

Compound interest = P (1+ ) ^nt

Continuous

P= $ 8000

t = 6

r = 6.25%

= 0.0625

n = 1

Compound interest = 8000 (1+) ^1×6

= 8000 (1 + 0.0625) ^6

= 8000 (1.0625) ^ 6

= 8000× 1.4387

= $11,509.6

Semi- annually

P= $ 8000

t = 6

r = 6.3%

= 0.063

n = 2

Compound interest = 8000 (1+) ^2×6

= 8000 (1 + 0.063) ^12

= 8000 (1.063) ^12

= 8000× 1.4509

= $11,607.0

Investing $ 8000 semi-annually at 6.3% for 6 years yields greater return

Therefore the answer is (A)

What is the approximate length of arc s on the circle below? use 3.14 for . round your answer to the nearest tenth. 14.1 in. 22.

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
PLEASE SEE ATTACHED IMAGE.

The length of an arc, by definition is given by:
s = R * theta
Where,
R: radio
theta: angle of the bow.
We then have to replace:
s = (6) * (135 * (pi / 180))
s = 14.1 in
Answer:
The length of the arc s is:
s = 14.1 in
