Answer:
78.71 mph
Step-by-step explanation:
You're looking for the solution to ...
d = 88
0.0015r^2 +r = 88
0.0015r^2 +r -88 = 0
Using the quadratic formula*, we find ...
r = (-1 +√(1² -4(0.0015)(-88)))/(2×0.0015)
r = (-1 +√1.528)/0.003 = 0.236123/0.003 = 78.7077
The speed of the car was about 78.71 mph.
_____
* The quadratic formula will also give a negative answer of about -745 mph, which is not relevant to the situation.
Answer:
slope=1 y-intercept=5
Step-by-step explanation:
there isn't much to it, but if you want me to show my work I will
To be able to compare the rates, we will write them in fraction form.
The fraction that represents Joe's rate is:
and the fraction that represents Bob's rate is:
Simplifying the above fractions, we get:
Since:
then Bob and Joe did not work at the same rate.
Answer:
No, Bob and Joe did not work at the same rate.
