A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its r
frosja888 [35]
You’re gonna have to use the quadratic formula here and a bit of thinking. We know y is height, and once it touches the ground, it will be 0.

(-b +- sqrt b^2 - 4ac)/2a
2 +- sqrt(4 + 48(400))/-32
(2 +- 138.58)/-32
We don’t want a negative time because it’ll make no sense. So do subtraction

(2-138.58)/-32 = 4.27 seconds aka 4.3 seconds

A long year-end status report for work is 130 pages long. You need to print 17 copies for a meeting next week. How much is the p
Nikitich [7]
The first thing you should do in this case is to know how much paper you need to print for the 17 copies.
 We have then:
 (17) * (130) = 2210
 Then, you must calculate the number of reams you need:
 n = (2210) / (500) = 4.42
 You need 4 full reams and 42% of a fifth ream. So, the cost will be
 C = (4.42) * (3.44) = 15.2048 $
 The unit cost of each paper is:
 Cu = (15.2048) / (2210) = 0.00688 $
 answer
 the paper is going to cost 0.00688 $ for those reports

erastova [34]

Answer:

Step-by-step explanation:

x_0=0

x_1 =  $40

so delta change is $40.  Now we can write the equation as

y = 40x, where y is the total saving account amount.

So after the 6th deposit, her total saving is $240.

y = 40(6) => 240
