Check the pictures below.
if we knew the roots/solutions of the equation, we can set h(s) = 0 and solve for "s" to find out how many seconds is it when the height is 0.
if you notice in the first picture, when f(x) = 0, is when the parabola hits a root/solution or the ground, for David he'll be hitting the water surface, and the equation that has both of those roots/solutions conspicuous is
h(s) = -4.9(s - 2)(s + 1).
Answer:
4.86
Step-by-step explanation:
Melanie uses 8.1 pints of blue paint and white paint for her bedroom
2/5 of this amount is blue paint
Therefore the amount of white paint can be calculated as follows
= 2/5
= 0.4×100
= 40%
60/100 × 8.1
= 0.6 × 8.1
= 4.86
Hence 4.86 pints of white paint will be used to paint the bedroom
P(CIY)=[P((C and Y)]/P(Y)
P(C)=40/146=20/73
P(Y)=30/146=15/73
Thus:
P(C and Y)=15/146=
Hence:
P(CIY)=(15/146)/(15/73)=1/2
Answer:
-70x + 21
Step-by-step explanation:
1-8 = -7.
-7(10x-3)
Distribute, you get -70x + 21.
Answer:
-2/3
Step-by-step explanation:
To find the slope, pick two points on the line, and use the slope formula
( 0,50) and (30,30)
m = ( y2-y1)/(x2-x1)
= (30-50)/(30-0)
= -20/30
= -2/3
