Answer:
The answer is below
Step-by-step explanation:
a) The integral
means the total change in level of water in inches from 1 am to 10 am. That is the water level change measured in inches between 1 am and 10 am
b) 7 pm is represented as t = 19 hours, while midnight is represented as t = 24 hours, hence the water level change between 7 pm and midnight is:

c) Using casio calculator to evaluate the integral gives:
= 2.54 inches
D) The total daily change in water level =
= 0.35 inches
You would do an arithmetic sequence
use A1 +(n-1)d to calculate number of seats in the last row
An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119 seats in the last row
now use a sum sequence to find total number of seats
Sn = n(a1 + an)/2
Sn = 24(4+119)/2
Sn = 24(123) /2
Sn = 1476 total seats
78 / 0.26 = 300 so the answer is 300
Answer:
2
Step-by-step explanation:
It sounds like we are pretending A is the universe. The only numbers in our world are 1,2,3,4, and 5.
You are given B is all numbers greater than 2.
The complement of B would all the elements not listed in B.
The elements in B are 3,4, and 5, since we are looking for numbers greater than 2 in our world of numbers above.
The elements not in B are 1 and 2.
So B complement is {1,2}.
There are 2 elements in our set for B complement. The elements that were counted were just the element 1 and the element 2.
Answer:
The constant speed with Ed is travelling is 60 mile per hour
Step-by-step explanation:
Given as :
The distance cover to travel from Jefferson to Holden is (D1) 250 miles
The distance cover to travel from Holden to Paxton is (D2) 50 miles
Total time taken to complete entire journey = T = 5 hours
Let The constant speed of Ed = S mph
Time =
Or, Time =
+
Or, 5 hour =
+
Or, 5 × S = 250 + 50
So, 5 × S = 300
∴ S =
I.e S = 60 mph
Hence , The constant speed with Ed is travelling is 60 mile per hour Answer
