Answer:
[tex]f_{ave}[/tex] = [tex]{\frac{10 }{3\pi }[/tex]
Step-by-step explanation:
To find - Find the average value fave of the function f on the given interval. f(x) = 5 sec²(x/6), [0, 3[tex]\pi[/tex]/2]
Proof -
We know that,
Average value of f in the interval [a, b] is -
[tex]f_{ave}[/tex] = [tex]\frac{1}{b - a}\int\limits^b_a {f(x)} \, dx[/tex]
Now,
Here a = 0, b = [tex]\frac{3\pi }{2}[/tex], f(x) = [tex]5sec^{2}(\frac{x}{6} )[/tex]
Now,
[tex]f_{ave}[/tex] = [tex]\frac{1}{\frac{3\pi }{2} - 0}\int\limits^{\frac{3\pi }{2} }_0 {5sec^2 ({\frac{x}{6} }) } \, dx[/tex]
= [tex]{\frac{2 }{3\pi }}\int\limits^{\frac{3\pi }{2} }_0 {5sec^2 ({\frac{x}{6} }) } \, dx[/tex]
= [tex]{\frac{10 }{3\pi }}\int\limits^{\frac{3\pi }{2} }_0 {sec^2 ({\frac{x}{6} }) } \, dx[/tex]
= [tex]{\frac{10 }{3\pi }}[\ {tan({\frac{x}{6} }) }|^{\frac{3\pi }{2} }_0 \, ][/tex]
= [tex]{\frac{10 }{3\pi }}[\ {tan({\frac{x}{6} }) - tan({0) } \, ][/tex]
= [tex]{\frac{10 }{3\pi }}[ {1 - 0 } ][/tex]
= [tex]{\frac{10 }{3\pi }[/tex]
⇒[tex]f_{ave}[/tex] = [tex]{\frac{10 }{3\pi }[/tex]
Each side of a square sandbox is 36 inches long. What is the area of the sandbox
The area of the square sandbox is 1,296 square inches
What is area of square?The area of a square is the measure of the space or surface occupied by it. It is equal to the product of the length of its two sides. Since the area of a square is the product of its two sides, the unit of the area is given in square units.
Area of a square = Side × Side
= [tex]Side ^{2}[/tex]
According to the question
Side of a square sandbox = 36 inches
Therefore,
The area of the square sandbox = [tex]Side ^{2}[/tex]
= [tex](36)^{2}[/tex]
= 1,296 square inches
Hence, the area of the square sandbox is 1,296 square inches

Answer:
20 cups
Step-by-step explanation:
Jada poured 0.45 liters of juice into several cups
9 liters was poured into each cup
Therefore the number of cups that Jada will fill up in the party can be calculated as follows
= 9/0.45
= 20
Hence Jada will fill up 20 cups

Jaina and Tomas compare their compound interest accounts to see how much they will have in the accounts after three years. They substitute their values shown below into the compound interest formula.
The question is incomplete. The complete question is :
Jaina and Tomas compare their compound interest accounts to see how much they will have in the accounts after three years. They substitute their values shown below into the compound interest formula. Compound Interest Accounts Name Principal Interest Rate Number of Years Compounded Jaina $300 7% 3 Once a year Tomas $400 4% 3 Once a year. Which pair of equations would correctly calculate their compound interests?
Solution :
It is given that Jaina and Tomas wants to open an account by depositing a principal amount for a period of 3 years and wanted to calculate the amount they will have using the compound interest formula.
So for Jiana :
Principal, P = $300
Rate of interest, r = 7%
Time, t = 3
Compounded yearly
Therefore, using compound interest formula, we get
[tex]$A=P\left(1+\frac{r}{100}\right)^{t}$[/tex]
[tex]$=300\left(1+\frac{7}{100}\right)^{3}$[/tex]
[tex]$=300(1+0.07)^3$[/tex]
Now for Tomas :
Principal, P = $400
Rate of interest, r = 4%
Time, t = 3
Compounded yearly
Therefore, using compound interest formula, we get
[tex]$A=P\left(1+\frac{r}{100}\right)^{t}$[/tex]
[tex]$=400\left(1+\frac{4}{100}\right)^{3}$[/tex]
[tex]$=400(1+0.04)^3$[/tex]
Therefore, the pair of equations that would correctly calculate the compound interests for Jaina is [tex]$A=300(1+0.07)^3$[/tex] .
And the pair of equations that would correctly calculate the compound interests for Tomas is [tex]$A=400(1+0.04)^3$[/tex] .

Answer:
√(300×3)=√900=√30²=±30 is your answer
Suppose that P(n) is a propositional function. Determine for which nonnegative integers n the statement P(n) must be true if a) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n 2) is true. b) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n 3) is true. c) P(0) and P(1) are true; for all nonnegative integers n, if P(n) and P(n 1) are true, then P(n 2) is true. d) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n 2) and P(n 3) are true
Solution :
a). [tex]$P(0)$[/tex] is true
Then ,[tex]$P(0+2)=P(2)$[/tex] is true.
[tex]$P(2+2)=P(4)$[/tex] is true
[tex]$P(4+2)=P(6)$[/tex] is true.
Therefore, we see that [tex]$P(n)$[/tex] is true for all the even integers : [tex]$\{0, 2,4,6,...\}$[/tex]
b). [tex]$P(0)$[/tex] is true
Then ,[tex]$P(0+3)=P(3)$[/tex] is true.
[tex]$P(3+3)=P(6)$[/tex] is true
[tex]$P(6+3)=P(9)$[/tex] is true.
Therefore, we see that [tex]$P(n)$[/tex] is true for all the multiples of 3 : [tex]$\{0, 3,6,9,12,...\}$[/tex]
c). [tex]$P(0)$[/tex] and [tex]$P(1)$[/tex] is true, then [tex]$P(0+2)=P(2)$[/tex] is true
[tex]$P(1)$[/tex] and [tex]$P(2)$[/tex] is true, then [tex]$P(1+2)=P(3)$[/tex] is true.
[tex]$P(2)$[/tex] and [tex]$P(3)$[/tex] is true, then [tex]$P(2+2)=P(4)$[/tex] is true.
So, we observe that [tex]$P(n)$[/tex] is true for all the non- negative integers : [tex]$\{0, 1,2,3,4,5,6,...\}$[/tex].
d). [tex]$P(0)$[/tex] is true,
So, [tex]$P(0+2)$[/tex] and [tex]$P(0+3)$[/tex] is true or [tex]$P(2)$[/tex] and [tex]$P(3)$[/tex] is true.
Now, [tex]$P(2)$[/tex] is true.
Again, [tex]$P(2+2)$[/tex] and [tex]$P(2+3)$[/tex] is true or [tex]$P(4)$[/tex] and [tex]$P(5)$[/tex] is true.
Now, [tex]$P(3)$[/tex] is true.
Again, [tex]$P(3+2)$[/tex] and [tex]$P(3+3)$[/tex] is true or [tex]$P(5)$[/tex] and [tex]$P(6)$[/tex] is true.
Thus,
[tex]$P(n)$[/tex] is true for all the non- negative integers except 1 : [tex]$\{0, 2,3,4,5,6,...\}$[/tex].

He is paid $0.06 for each calendar he delivers.
What is his total pay for a
week in which he delivered the following number of calendars?
Mon- 100
Tues- 130
Wed- 145
Thurs- 138
Fri- 210
Answer: $4.34
Step-by-step explanation:
Mon: 0.6x100= 60 cents
Tue: 0.6x130= 78 cents
Wed: 0.6x145= 87 cents
Thurs: 0.6x138= 82.8 cents
Fri: 0.6x210= 126 cents
60+78+87+82.8+126= 433.8 cents
There are 100 cents in a dollar
4.33.8 cents, so 4.34 if you round up (if the last number is five or greater round up)

You are putting money into a bank account. You start with $100 and add $12 every month. The total amount of money in your account can be represented by the following equation. (where T is total amount and M is the number of months):
T = 100 + 12 M
If you have $208, how many months have passed?
Show the equation and how you got the answer.
100
Add 12 every month
Ex: 100 + 12
100 + 12 + 12+ 12+ 12+ 12+ 12+ 12+ 12+ 12
It wound not be 100 x 9 because 100 x 9 is 900
Therefore 9 months
9 x 12 = 108
so that would be 100+108= 208

A back account pays an interest rate of 6% every 1 year. You deposit $5000 into the account. How much money will you have in 5 years?
A. $7092
B. $3449
C. $3670
D. $6691
Answer:
C: $6691
Step-by-step explanation:
This problem is one in compound interest. The general formula is shown below. The principal, P, is $5000, the annual interest rate, r, is 0.06 (expressed as a decimal fraction), and the number of years, t, is 5 years: A represents the Amount after 5 years:
A = P(1 + r)^t becomes A = ($5000)(1 + 0.06)^5, or
A = (5000)(1.06)^5 = $6691.12 (Answer D)
