Answer:
(3)
Step-by-step explanation:
(1), (2) and (4)
can be written as Fr= p1-p2, F and r are inversely proportional
(3) r is directly proportional with F which is opposite to the given formula
hence this is incorrect
12(0.59)= 7.08
10-7.08= 2.92
Sofia will get $2.92 in change.
Hope this helps!
Answer:
0.85x+2.75<=10
Step-by-step explanation:
x is the number of miles he drives
the +2.75 is the flat rate
the <=10 is it must cost no more than 10, it may cost less, or equal, but no more than 10
The response time includes the round-trip signal time plus the robot's travel time.
59 min = 2*(9.5 min) +travel time
59 min -2*(9.5 min) = travel time = 40 min
The speed is distance / travel time
speed = (52.8 m)/(40 min) = 1.32 m/min
The robot's average speed was 1.32 meters per minute.
The area of revolution is the integral of 2π(radius)(differential of arc length).
= (2π/27)*(72^(3/2) -38.25^(3/2)) ≈ 87.1215
