A, B, C, D form a complete circle which is 360 degrees.

Add all 4 together:

A + 2A + 4A+ 3A = 360

10A = 360

Divide both sides by 10:

A = 360/10 = 36

Now we know A so can calculate the rest:

B = 2A = 2(36) = 72 degrees

C = 4A = 4(36) = 144 degrees

D = 3A = 3(36) = 108 degrees

How much is 400.00 invested at 9% interest compounded continuously be worth after 3 years

blagie [28]

COMPOUNDED
not simple interest,
compound interest is neat since you earn interest on the interest you earned

ok so what you use is F=Pe^(rt)
F=future or ending amount
P=present amount
e=base of the natural log (some digits are 2.71828182845)
r=rate in decimal
t=time in years

presen amount is 400
rate is 9% or 0.09
time is 3 years

F=400e^(0.09*3)
F=400e^(0.27)
F=523.986
round
F=523.99

The function V(r)=4/3 nr3 can be used to find the volume of air inside a basketball given its radius. What does V(r) represent?

denis-greek [22]

Answer:

V(r) represent the volume of air inside a basketball in cubic units for a given radius r in units

Step-by-step explanation:

we have the function

$V(r)=\frac{4}{3}\pi r^{3}$

where

V is the volume of a sphere (dependent variable or output function)

r is the radius of the sphere (independent variable or input variable)

therefore

V(r) represent the volume of air inside a basketball in cubic units for a given radius r in units
