the altitude of A (in feet) of a plane T minutes after liftoff is given by a=3400t + 600. How many minutes after liftoff is the
____ [38]

If our equation is a = 3400t + 600, and we have a target altitude of 21,000, we just need to plug that in for a.

21,000 = 3,400t + 600. Now subtract 600 from both sides.

20,400 = 3,400t. now divide both sides by 3,400.

6 = t.

We get that our answer is at 6 minutes we get an altitude of 21,000 feet!

mina [271]
Combine costs
59.99(3) + 75 = 179.97 + 75
179.97 + 75 = $254.99 (total cost)
Now add tax: 8% = 0.08
254.99 * 0.08 = 20.3992
254.99 + 20.3992 = 275.3892

Solution: bill would be around $275
