Use the unit circle to find the inverse function value in degrees.tan^-1 sqrt 3

The correct answer would be 60 degrees. Since you are asked to find an angle that the tangent is equal to sqrt 3. The only angle that is equal to that given the interval is 60 degrees. So that is the correct answer. I hope this answer helped you.

What is the volume of the composite figure shown? (Use 3.14 for π.)

Nimfa-mama [501]

$The\ volume\ of\ the\ cone:V_1=\frac{1}{3}\pi r^2 H\\(r-a\ radius;\ H-height)\\------------------\\r=7ft;\ H=7ft\\\\V_1=\frac{1}{3}\pi\cdot7^2\cdot7=\frac{1}{3}\pi\cdot343=\frac{343}{3}\pi\ (ft^2)\\-------------------\\The\ volume\ of\ the\ cylinder:V_2=\pi r^2 H\\(r-a\ radius;\ H-height)\\-------------------\\r=7ft;\ H=6ft\\\\V_2=\pi\cdot7^2\cdot6=294\pi\ (ft^3)\\------------------------\\The\ volume\ of\ the\ composite\ figure: V_F=V_1+V_2$

$V_F=\frac{343}{3}\pi+294\pi=\frac{343}{3}\pi+\frac{294\cdot3}{3}\pi=\frac{343}{3}\pi+\frac{882}{3}\pi=\boxed{\frac{1225}{3}\pi\ (ft^3)}\\\\\approx\frac{1225}{3}\cdot3.14}=\frac{3846.5}{3}\approx\boxed{1,282.17\ (ft^3)}\leftarrow answer$

URGENT!! I NEED HELP ASAP NOT ROCKY

Anestetic [448]

Answer:

$9000

Step-by-step explanation:

Given

Monthly payment P = $300
Time t = 3 years = 36 months
Number of payments n = 36
Interest rate r = 12% PA = 1% per month = 0.01 times

Use loan payment formula:

P = r(PV) / (1 - (1 + r)⁻ⁿ),
where P- monthly payment, PV - present value (amount of the loan), r -rate of interest, n- number of payments

Substitute values and solve for PV:

300 = (0.01*PV) / (1 - (1 + 0.01)⁻³⁶)
PV = 300*(1 - 1.01⁻³⁶ )/ 0.01
PV = 9032.25 ≈ $9000 (rounded to the nearest hundred dollars)
