A is your answer
Explanation:
When dealing with functions, x’s never repeat.
(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:
Step-by-step explanation:
Using the formula for calculating simple interest
SI = principal × rate × time/100
Given
Principal = $8750
Rate = 9.75%
Time = 2years
Substitute
Interest = 8750×9.75×2/100
Interest = 87.59×19.5
Interest = 1,706.25
Hence the finance charge to the nearest whole dollar is $1706
