Answer: 11,499.0145103 ft (60.5^{2}\pi)

Step-by-step explanation:

a =  \pi r^{2}
121 = d, d = rx2
121/2 = 60.5
60.5^{2} = 3660.25
3660.25 x \pi = 11,499.0145103

kenny6666 [7]

Answer:

65 miles

Step-by-step explanation:

There are two simultaneous equations . Remeber that v=d/t, 1hour = 60 minutes.

1. 40 = (d+15)/(t+0.5)

2. 50 = d/t

solving: d= 25 miles and t=0.5 hours.

The distance traveled is:

D=d+d+15

D=65 miles

B) Now, let’s try “what if”. What if you had medical bills for $10,000 for a minor surgery? What would each of the insurance pol
cricket20 [7]

Answer:

The insurer's part of the medical bill is 80 percent of the medical bill after deductible

The insurer would cover 80 percent of the insured's claims on the medical bill based on coinsurance agreement. However, the insured would have to pay deductible prior to coinsurance(80,20 share of bill)

Example: if insured's annual deductible is $2000 and coinsurance is 80:20, a medical bill of $10000, assuming the insured has not paid any deductibles, would amount to 80% of $8000(after subtracting deductibles) for the insurer"s cover and the rest for the insured.

Insurance deductibles are paid before your health plan covers its part of the medical bill, usually 80 percent. Depending on your agreement with the insurer there could also be a copay on the insurance policy.

Factor x^2 -3x-3 in F5(x) p=5
denis-greek [22]
-3=2-5\implies -3\mod5=2\mod5

When taking a polynomial modulo n, you reduce its terms' coefficients modulo n, so that, in conjunction with the result above,

x^2-3x-3\equiv x^2-3x+2\mod5

For completeness, the linear term's coefficient should also get reduced in the same way as the constant term, so that

x^2-3x-3\equiv x^2+2x+2\mod5
