(a) (i) In first 4 minutes Mary's speed was 600 / 4 = 150 m / minute
(ii) in last 4 minutes her speed was (1000-600) / 4 = 400/4 = 100 m/min
(b) Marys average speed for the whole journey = 1000/8 = 125 m/min
(c) 200 m
(d) Peter arrived at school after 7 minutes . Mary took 8 minutes. Peter first.
(e) Where they met is given by where the 2 curves intersect. That is at time 6.8 minutes and 880 m from Mary's home
(f) At t= 4 dsitance between then is 600 - 400 = 200 m

Answer:
Mr. Johnson has 12 possibilities.
Step-by-step explanation:
The information provided are:
- Mr. Johnson has a white shirt, a plaid shirt, and a blue shirt.
- Mr. Johnson has four pairs of pants, black, brown, gray, and white.
- He chooses one shirt and one pair of pants.
Compute the number of ways to select a shirt and a pair of pants as follows:
Total number of ways = Number of Shirts × Number of pair of pants
Thus, Mr. Johnson has 12 possibilities.
<span>(7x^4+x+14)/(x+2)
</span>(7x^4+x+14)----------------------|(x+2)
-14x³+x+14-------------------------7x³-14x²+28x-55------> q(x)
28x²+x+14
-55x+14
110+14=124------------------------> r(x)
<span>
</span>r(x)=124
b(x)=x+2
q(x)=7x³-14x²+28x-55
then
q(x) + r(x)/b(x)---------> (7x³-14x²+28x-55)+(124)/(x+2)
the answer is (7x³-14x²+28x-55)+(124)/(x+2)
