Since

, and you have a corresponding term in the given Riemann sum of

, you know the integral is being taken over an interval of length 5, so you can omit the second choice.
Next,

corresponds to

with

. The fact that

alone tells you that the interval of integration starts at 3, and since we know the interval has length 5, that leaves the first choice as the correct answer.
11/12 of a minute is 55 seconds
Answer: 24.34 is his balance.
Step-by-step explanation:
66% divided by 365 days is the answer i think
1. Writing p as a function of c gives
P =2c-250
Where C is the number of candy bar
P is the number of candy bar sold.
2. This is expressed as
0 =< C <= 250
3. This is expressed as
0 =< C =< 250
4. Amount made from selling candy bar in the set of interger between 0 to 500
C is given as 500
From the equation P=2C-250
P=2×500-250
P=1000-250 =750.
P=750
5. Amount made selling candy bar for the set of real numbers between 0 and 250
C is equal to 250
From the equation, we have
P=2×250-250
P=500-250 =250.
