A hot air balloon leaves the ground and ascends at a rate of 5 feet per minute for 4 minutes.
aleksley [76]

When the balloon is on the ground, it is at point 0. It starts to go up at 5 f/m for a time of 4 minutes. So we will multiply 5 by 4 to get 20. At this point, the balloon is 20 feet off the ground. However, we now know that the balloon descends at 2 f/m at a time of 7 minutes. So we must multiply 2 by 7 to get 14. So we know it was at 20, and then it went down by 14.

20 - 14 = 6 feet

This means that the balloon is now 6 feet above the ground.

I hope I've helped! :)

Simplify each expression
Rasek [7]

Answer:

= a⁸/b⁻¹⁰

Step-by-step explanation:

Simplify the expression

(a^2b^-3/a^-2b^2)^2

= a⁴b⁻⁶/a⁻⁴b⁴

Using the law of indices

= a⁴⁻⁽⁻⁴⁾/b⁻⁶⁻⁴

= a⁴⁺⁴/b⁻¹⁰

= a⁸/b⁻¹⁰
