Answer:
The rate at which the distance between the two cars is increasing is 30 mi/h
Step-by-step explanation:
Given;
speed of the first car, v₁ = 24 mi/h
speed of the second car, v₂ = 18 mi/h
Two hours later, the position of the cars is calculated as;
position of the first car, d₁ = 24 mi/h x 2 h = 48 mi
position of the second car, d₂ = 18 mi/h x 2 h = 36 mi
The displacement of the two car is calculated as;
displacement, d² = 48² + 36²
d² = 3600
d = √3600
d = 60 mi
The rate at which this displacement is changing = (60 mi) / (2h)
= 30 mi/h
Answer:
It should be C
Step-by-step explanation:
2.85+2.85=5.7
5.7×7.7=43.89 m²
Answer:
$12
Step-by-step explanation:
Given data
Radius= 2in
cost = $4
New jaw breaker radius= 6in
cost=???
If 2 in jaw breaker cost $4
6in jaw breaker will cost x
cross multiply
6*4= 2*x
24= 2x
x= 24/2
x= $12
Hence the 6 in jawbreaker will cost $12
(5-3)/(9-3) is 2/6
The slope is 1/3
