Answer:

Step-by-step explanation:

Formula of the circumference of  the circle is 2*pi*r

1.A=pi*r^2=pi*3^2=9pi

2.A=pi*10.8^2=

3.r=14/2=7 so

A=pi*7^2=49pi

4. A=pi*(31/2)^2Km^2=15.5^2*pi

5.  semicircle

 A=pi*16^2/2cm^2=

6.A=pi*(22.6/2)^2=11.3^2*pi

In the diagram below what is the length of arc AC ? Round to the nearest inch.
valentina_108 [34]
As AB is a diameter, then m∠CBA=180^{0}-75^{0}=105^{0}. 
∠CBA is a central angle, so its measure multiplied by radius is the length of arc AC.
Note that 105^{0}=7\cdot 15^0 and 15^{0}= \frac{\pi}{12}. Then 105^{0}= \frac{7\pi}{12} = \frac{7\cdot 3.14}{12}=1.83 and length of the arc is 12\cdot 1.83=21,96.The correct answer is 22 in.

Assume that you purchased a new car today and financed $55,000 of the price on a 72-month payment contract with a nominal rate o
katovenus [111]

Answer:

The amount that your loan balance will be when you pay off the car is $20,566.18.

Step-by-step explanation:

Step 1. Calculation of monthly payment

This can be calculated using the formula for calculating the present value of an ordinary annuity as follows:

PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)

Where;

PV = Present value or the cost of the new car = $55,000

P = Monthly payment = ?

r = Monthly nominal rate = Nominal rate / 12 = 6% / 12 = 0.06 / 12 = 0.005

n = number of months = 72

Substitute the values into equation (1) and solve for P, we have:

$55,000 = P * ((1 - (1 / (1 + 0.005))^72) / 0.005)

$55,000 = P * 60.3395139355201

P = $55,000 / 60.3395139355201 = $911.51

Step 2. Calculation of the loan amount balance when you pay off the car

This can be calculated using the ballon payment formula as follows:

P = (PV - (Ballon / (1 + r)^n)) * (r / (1 – (1 + r)^-n)) ...................... (1)

Where:

P = Monthly payment = $911.51

PV = Present value or the cost of the new car = $55,000

Ballon = Ballon payment or the loan amount balance when you pay off the car = ?

r = Monthly nominal rate = Nominal rate / 12 = 6% / 12 = 0.06 / 12 = 0.005

n = number months to pay off the loan amount balance = 48

Substituting the values into equation (1) and solve for Ballon, we have:

911.51 = (55,000 - (Ballon / (1 + 0.005)^48)) * (0.005 / (1 - (1 + 0.005)^-48))

911.51 = (55,000 - (Ballon / 1.27048916109538)) * 0.0234850290479363

911.51 / 0.0234850290479363 = 55,000 - (Ballon / 1.27048916109538)

38,812.39 = 55,000 - (Ballon / 1.27048916109538)

Ballon / 1.27048916109538 = 55,000 - 38,812.39

Ballon / 1.27048916109538 = 16,187.61

Ballon = 16,187.61 * 1.27048916109538

Ballon = $20,566.18

Therefore, the amount that your loan balance will be when you pay off the car is $20,566.18.

Logarithm help needed
sashaice [31]

Answer:

See below.

Step-by-step explanation:

Helen made a mistake in the last step.

2^(4/3) / e = (∛(2^4) / e  = ∛(16) / e .

It is the cube root of  2^4 not the 4th root of 2^3.

Stephen made a mistake in the first step.

He replaced ln2 by 2 which is evidently wrong (e^ln2 = 2  NOT ln 2).
