if $5,000,000 isinvested at 4% interest compunded continuously, how much willl the investment be worth in 30 years
Katarina [22]
The answer is $16216987.55 (IMPORTANT: This is the answer assuming that the interest rate is annually. The quesiton says 'continuously' so I was a bit confused)

To solve this problem, you can use the compound interest formula. 

Here it is once you plug in the numbers: A = 5,000,000 ( 1 + .04) ^30

Just solve the equation to find the solution.

Find the volumes of the figures below. I just need answers.
poizon [28]

Hello!

The volume of a cone is found by using the formula: V = 1/3πr²h.

Figure 1 --

From figure one, it shows us the radius, which has a length of 8 centimeters, and the height, which is 14 centimeters. With that values, we can substitute those values into the formula and solve.

V = 1/3π(8)²(14)

V = 1/3(64)(14)π

V = 64/3(14)π

V = 896/3π centimeters³, 938.29 centimeters³ (multiplied by π), and 937.81 centimeters³ (multiplied by 3.14).

Therefore, the volume of the first cone is 938.29 centimeters³.

Figure 2 --

From the second figure, the height of the cone is 19.6 and the diameter is 12. To find the radius, divide the radius by 2, which is will give the radius.

V = 1/3π(6)²(19.6)

V = 1/3(36)(19.6)π

V = 12(19.6)π

V = 235.2π, 738.53 (multiplied by 3.14), 738.90 (multiplied by π)

Therefore, the volume of the second cone is 738.90 units³.
