Answer:
a = -8
b = 19.5
c = 0.02
T will travel 81 m/s because addin six to 21 gives you 27 so take that times three and you get 81 m/s hope this helps
Answer:
The roots (zeros) are the
x values where the graph intersects the x-axis. To find the roots (zeros), replace and with 0
and solve for
x.
Exact Form:
x=−2±√52
Decimal Form:
x=0.11803398
…,−2.11803398
…
Step-by-step explanation:
The line passes by the points (2,-3) , (-2,5)
so the equation of a line passes by 2 points is (y-y1)/(x-x1) = slope
slope = (y2-y1)/ (x2-x1)
= (5-(-3)) / ( -2-2)
= 8/-4
= -2
then subs. in the 1st equation of the line
(y-(-3)) / ( x-2) =-2
so,, (y+3) = -2(x -2)
so the answer is the 1st one
to make sure ur equation is right subs in the equation by the point (0,1)
if R.H.S = L.H.S
then ur equation is right
