Answer:
2(3.5g - 4.5h)
Step-by-step explanation:
factoring the expression (i think that what its called) i divided the expression into two and then put two on teh isde of the parenthesis to show that you multiply it again
Answer:
The answer is B
Step-by-step explanation:
1)
These are in Y = MX + B form
The first line has a positive slope, so the coefficient "M" is positive.
The second line has a negative slope, so the coefficient "M" is negative.
2)
The first line has a filled in dot at Y = 2.
Since it's to the left (less than X direction)...
X <= 0
The second has an empty circle at Y = 4.
Since the line goes to the right....
0 < X
3)
Also, the "+2" and the "+4" in the equation as the "+ B" indicates where each line will cross the Y axis.
From these things, we can infer that B is the correct answer.
Answer:
after 10 seconds
Step-by-step explanation:
h=-16t^2+v0*t+h0
ground level is h0 with a measure of 0
160 is v or velocity
0=-16t^(2)+160t+0
0=-16t^(2)+160t
0=16t(-t+10)
0/16t=(-t+10)
0=-t+10
-10=-t
10=t
t=10
