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:
x-intercept = -56
y-intercept = - 14
Step-by-step explanation:
x + 4y = -56
x- intercept :
y = 0
x + 4*0 = - 56
x-intercept = -56
y-intercept:
x=0
0 + 4y = - 56
4y = -56
y = - 14
y-intercept = - 14
