Angle 2 is 110° and the other angles are 70°
It would be: (y2-y1) / (x2-x1) = (9-(-9)/5-5 = 18/0 = undefined
OPTION D IS YOUR ANSWER.........
Answer:
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s ----> the speed in mph
d ----> the distance in miles
t ----> the time in seconds
step 1
In the first hour they drive at a rate of 60 mph
Find the distance traveled
we have
substitute
so
The remainder of the trip is equal to
step 2

Answer:
3 seconds
Step-by-step explanation:
Maximum height=150
150=-16t^2+96t+6
-16t^2+96t-144=0
-16(t^2-6t+9)=0
-16(t-3)^2=0
t=3 seconds
