C) How long is the potato in the air? *hint set h=0*<br> if h=-2(t-3)2+32
Galina-37 [17]

Answer:

if you meant to put (t-3)^{2}, then the answer is 7

Step-by-step explanation:

h=-2(t-3)^{2}+32

solve for t

0=-2(t-3)^{2}+32

subtract 32 from both sides

-32=-2(t-3)^{2}

divide both sides by -2

16=(t-3)^{2}

find suare root of 16

4= t-3

add 3 to both sides

7 = t

What is the x-coordinate of the point that divides the directed line segment from K to J into a ratio of 1:3?
ruslelena [56]
Since we need a point that divides K-->J into two segments in a 1:3 ratio, let's flip it to a 3:1 ratio in the J-->K direction. That means that this point is 3/(3+1) = 3/4 of the way up line JK.
Let's take 3/4 of the x of K (plus the 1 for the x of J):
3/4×(9 - 1) + 1 (because the beginning ofvthe line, at J, has an x of 1)...
3/4×(8) + 1 = 6 + 1 = 7
Therefore the answer is C) 7
