We are given that Jerry had his cruise control set at 60mi/h for 4 hours.
The rate of change is the second name of slope.
We are given rate of 60 miles per hour.
Thereofore, slope would be just 60.
And because it's keep 60 miles per hour for next 4 hours that is constant for next four hours.
Therefore it would stay positive.
So, we can say
1. Slope = 60
2. Positive.
Answer:
relationship between base and perpendicular is given by tan angle
tan angle = perpendicular/base
tan angle =21/41
angle =tan -¹(21/41)=27

Answer:
x = 3
Step-by-step explanation:
Let the altitude from B to AC intersect at point D. Then BD is a height of the triangle with base AC
ΔABD is a 30-60-90 triangle since m∠A = 30
Therefore, AB = 2(BD) or BD = AB/2 = (x+3)/2
Area of the triangle = bh/2 = AC(BD)/2 = 4x(x + 3)/(2)(2)
= x(x + 3) = 18
(x + 6)(x - 3) = 0
x = -6 or x = 3
x cannot equal -6, so x = 3
