d + 4 = -9

d + 4 = 9

So...

d = -13

d = 5

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!
