Five different problems in one post? That's a turn-off for some potential helpers. Suggest you post only ONE problem at a time.

In regard to the first problem: Your Principal (P) is $8000. The Interest Rate (i) is 19%. The elapsed time is 7 years. Using the formula for continuous compounding:

A = P e^(rt), where "e" is the very common base with value approx. 2.718.

Here, the amount due is A = $8000 * e^(0.19 * 7). Can you evaluate this?

Answer:

1/3(5.2)h cm³

Step-by-step explanation:

A solid right pyramid has a regular hexagonal base with an area of 5.2 cm2 and a height of h cm. Which expression represents the volume of the pyramid?

One-fifth(5.2)h cm3 StartFraction 1 Over 5 h EndFraction(5.2)h cm3

One-third(5.2)h cm3 StartFraction 1 Over 3 h EndFraction(5.2)h cm3

Volume of the pyramid = 1/3 × area × height

Area = 5.2 cm²

Height = h cm

Volume of the pyramid = 1/3 × 5.2 cm² × h cm

= 1/3(5.2)h cm³

What is 15 increased by 60 percent? Let's work it out!

First, you must know what 60 percent of 15 is.

60 percent of 15
 15 times .60
equals
9.

So 60% of 15 is 9.

Increased is a word which means added.

So, 15 plus 9 (15+9) is 24.

Final Answer = 24.
