B is the answer that I got
Answer:
a dilation is different from a translation because it enlarges an image or shrink them instead of moving them. it's also different from rotation since it doesn't rotate but enlarge or shrink. it's way far from reflection because it enlarges or shrinks.
Answer:
205 dollars for the bike
Step-by-step explanation:
The rate of Sue is 1 car per hour: 1 (c/h)
then the rate of Steve is 2 (c/h) , because Steve works faster, he can wash twice the number of cars, for the same amount of time.
Thus If Steve and Sue work together, they can wash 1 + 2 = 3
(cars per hour).
That is, the rate of Steve and Sue working together, is 3 (c/h).
In the first 30 minutes, Sue washes half of the car.
The remaining half will be washed at a rate of 3 (c/h)
The main formula is Work = Time * Rate
where Work is washing (1/2)c, and rate is 3(c/h)
Time=Work/Rate =
1/ 6 h =(1/6)*60 min = 10 min
Answer: 10 min
First integrate the entire thing by letting multiplying by 1/2 the entire expression raised to exponent 1/2 - 1. That is,
0.5(1 + x³)^-0.5
Then, multiplying this by the derivative of those inside the parentheses. The final answer would be,
(0.5)((1 + x³)^-0.5)(3x²)
