First, we find the time spent accelerating:
s = ut + 1/2 at²; u = 0
10 = 1/2 5t²
t = 2 seconds
Velocity at point B:
v = u + at; u = 0, a = 5 m/s², t = 2 s
v = (5)(2) = 10 m/s
Now, the same velocity is at C so we find the time decelerating to 0 in CD
v = u + at, v = 0, u = 10 m/s, a = -4 m/s²
0 = 10 - 4t
t = 2.5 seconds
Total time = time(AB) + time(BC) + time(CD)
20 = 2 + time(BC) + 2.5
time(BC) = 15.5 seconds
Distance = velocity x time
BC = 10 x 15.5
= 155 m
17) 388 in^2
18) 585 in^2
19) 960 ft^2
*fyi- ^2 means squared just in case you didn’t know also hope the picture helps!

Answer: 14400</h3>
Chances are your teacher doesn't want you to enter any commas. You won't type in the dollar sign either.
============================================================
Explanation:
Nice work on selecting the correct equation to set up.
We'll cross multiply to help solve for x.
The idea of cross multiplication is that
turns into 
So,

That means the person would pay $14,400 on a property worth $800,000.
Answer:
and it's reciprocal is 
Step-by-step explanation:
4.5 is a number in between 4 and 5, as a fraction it is written as
. To get the reciprocal you need to change it to an improper fraction so it becomes
. The reciprocal will be 1 ÷
. This literally means the number will just invert and become 
Solution :
The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.
a).
does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.
b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.
The regression model provides the prediction and not the actual values.
