Answer:
9 units²
Step-by-step explanation:
A differential of area is ...
dA = ((2y -y²) -(y² -4y))·dy = (-2y² +6y)·dy
The indefinite integral of this will be ...
a = -2/3y³ +6/2y²
Then the definite integral over the limits [0, 3] will be ...
(-2/3·3³ +3·3²) - 0 = 9 . . . . square units
Answer: 2 + n less-than 14
Or 2 + n < 14
Step-by-step explanation:
Let n = number
Two more than a number is less than 14
n + 2 < 14
Or 2 + n < 14 which is the same as
2 + n less-than 14
Answer:
about 70.0 mph
Step-by-step explanation:
speed = distance/time
(300 ft)/(2.92 s)·(1 mi)/(5280 ft)·(3600 s)/(1 h) = (300·3600/(2.92·5280)) mi/h
≈ 70.0498 mi/h
