1) Note that this is a right triangle, and we can tell an isosceles one by the marks on the triangle.
2) So, we can use the Pythagorean Theorem, to find the side lengths since all we know for now is the hypotenuse:
[tex]\begin{gathered} a^2=b^2+c^2 \\ (3\sqrt[]{2})^2=x^2+x^2 \\ 2x^2=9\cdot2 \\ 2x^2=18 \\ \frac{2x^2}{2}=\frac{18}{2} \\ x^2=9 \\ x=\sqrt{9},\: -\sqrt{9} \\ x=-3,3 \end{gathered}[/tex]We can discard the negative value for there is no negative length. So, the answer is 3
Raymond invested $2,000 in an account that earns an 8% annual interest rate. Find a balance of his account after 4 years compounded the following ways round your answers to the nearest cent.
Answers
The rule of the compounded interest is
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]A is the new value
P is the initial value
r is the rate in decimal
n is the period
t is the time
He invested $2000
P = 2000
The account earns an 8% annual interest
r = 8% = 8/100 = 0.08
The balance is for 4 years
t = 4
For no 1 it is annual, then
n = 1
Substitute these values in the rule above
[tex]\begin{gathered} A=2000(1+\frac{0.08}{1})^{(1\times4)} \\ A=2000(1.08)^4 \\ A=2720.97792 \end{gathered}[/tex]Round it to the nearest cent means 2 d.p
[tex]A=2720.98[/tex]The balance is $2720.98
2. Semi-annual means
n = 2
So we will substitute n by 2
[tex]\begin{gathered} A=2000(1+\frac{0.08}{2})^{(2\times4)} \\ A=2000(1.04)^8 \\ A=2737.138101 \end{gathered}[/tex]Round it to the nearest cent
[tex]A=2737.14[/tex]The balance is $2737.14 in semi-annual
3. Quarterly means
n = 4
So we will substitute n by 4
[tex]\begin{gathered} A=2000(1+\frac{0.08}{4})^{(4\times4)} \\ A=2000(1.02)^{16} \\ A=2745.57141 \end{gathered}[/tex]Round it to the nearest cents
[tex]A=2745.57[/tex]The balance is $2745.57 quarterly
4. Monthly means
n = 12
Substitute n by 12
[tex]\begin{gathered} A=2000(1+\frac{0.08}{12})^{(12\times4)} \\ A=2000(1.006666667)^{48} \\ A=2751.332201 \end{gathered}[/tex]Round it to the nearest cent

An executive wishes to take out a $1.2 m mortgage. The yearly interest rate on the loan is 1.95% and the loan is for 20 years. What will the monthly repayments be? Give your answer in dollars and cents. Do not include commas or the dollar sign in your answer.
Answers
Mortgages are calculated using simple interest, so:
[tex]A=P(1+rt)[/tex]P= principal amount
r= interest rate
t= time
For P=1.2mill
r=1.95%
t=20years
The simple interest will be:
[tex]A=1200000(1+0.0195\cdot20)=1668000[/tex]Now divide the calculated amount by 20 to get the yearly fee:
[tex]\frac{1668000}{20}=83400[/tex]And finally divide it by 12 to get the monthly fee:
[tex]\frac{83400}{12}=6950[/tex]The exercutive will pay 6950 monthly
Some fabric shrinks when it is washed.
A piece of fabric is washed twice.
After the first wash, the area of the fabric is 75% of the area of the original piece of fabric.
After the second wash, the area of the fabric is 90% of the area of the fabric after the first
wash.
After these two washes, the area of the fabric is 2700 cm².
Calculate the area of the original piece of fabric.
Answers
After performing some mathematical operations, we know that the original area of the fabric is 4,000 cm².
What are mathematical operations?In mathematics, an operation is a function that converts zero or more input values into a discrete output value.The number of operands in the operation determines how complex it is.The four mathematical operations are functions that convert inputs that are numerical into outputs that are numerical (i.e., another number).These are addition, subtraction, multiplication, and division.So, the original area of fabric is:
The area after two washes is 2700 cm² which is 90% of the area after the 1st wash.Then:
x/100 × 90 = 270090x = 270000x = 270000/90x = 3000 cm²The area after 1st wash is 3000 cm².
Which is 75% of the original area.Then:
x/100 × 75 = 300075x = 300000x = 300000/75x = 4,000 cm²Therefore, after performing some mathematical operations, we know that the original area of the fabric is 4,000 cm².

5,624 ÷ 72 using estimation
Answers
=====================================================
Explanation:
5624 is close to 5600
72 is close to 70
Therefore, 5624 ÷ 72 is close to 5600 ÷ 70 = 80
Think of it like saying 56 ÷ 7 = 8 but then we add the zeros onto each to get what is shown above.
--------
Use your calculator to find that
5624 ÷ 72 = 78.111 approximately
which isn't too far from the estimate value of 80. Our estimate is an over-estimate.
Answer: 80
Step-by-step explanation:
First change the equation to the nearest tenth,
5620 divided by 70
Now, break up the 70 into ( 10 * 7 )
So first do 5620 divided by 10
5620 divided by 10 = 562
Now if we round to the nearest tenth again we get 560
Now we can divide 560 by 7
Which comes out to 80

Which of the following is the average rate of change over the interval [-5, 10] for the function g(x) = log2 (x+6)-3
A.4/5
B.5/4
C.4/15
D.15/4
Answers
It's answer is option(C) i.e, 4/15
What is Average rate of change?
The average rate of function f over the interval a≤x≤b is given by ,
(f(b) - f(a)) / (b - a)
It is the average amount by which the function changed per unit throughout that time period.
In this question the equation is given,
g(x) = log2 (x+6)-3
Solve this eq. by putting the values [-5, 10],
let, interval [-5, 10] = [a, b]
Then solve for g(a) and g(b), we know g(a) = g(-5),
g(-5) = log₂(-5+6) - 3
= log₂1 - 3
= 0 - 3
g(-5) = -3
Now, for g(b) = g(10)
g(10) = log₂(10+ 6) - 3
= log₂16 - 3
= 4 - 3
g(10) = 1
Now put these values in average rate formula,
Average rate = (g(b) - g(a)) / (b - a)
= (1 - (-3)) / (10 - (-5))
= (1 + 3) / (10 + 5)
= 4 / 15
Therefore, the average rate is 4/15 i.e, option(C)

Vladimir is looking to retire in 10 years. He has a plan to put $25,000 into an investment today that earns interest at a fixed amount per year. What would be a reasonable domain and range for a function modeling the total amount of the investment, including interest?explain your answer
Answers
If Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, considering the rate of interest to be (R%) per annum, the domain and range for a function modeling the total amount of the investment, including interest are as follows:
Domain [X = {0 ≤ years ≤ 10}]
Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]
As per the question statement, Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, and since there is no information about the rate of interest of that investment, we are considering the rate of interest to be (R%) per annum.
We are required to determine the domain and range for a function modeling the total amount of the investment, including interest using the question statement mentioned data and our assumptions.
Since the starting principal amount, say P is $25,000, given,
Time of investment, say T is 10 years, also given,
And considering the interest rate per year to be R (%),
Then after 10 years, the total amount Vladimir has is [25000( 1 + xR)].
Where, the Domain (No. of years ) is [X = {0 ≤ years ≤ 10}]
And Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]
Domain of a Function: In mathematics, the domain of a function is the set or group of inputs that is accepted by the function.Range of a Function: In mathematics, the range of a function is the set or group of outputs produced by the function using values from its domain.To learn more about Domain and Range of a Function, click on the link below.

The two balconies hold 94 and 91 people each; the rest of the seats are at the stage level. Solving the equation x + 94 + 91 = 400 will give you the number of seats on the stage level.
Answers
So first of all we have to solve this equation:
[tex]x+94+91=400[/tex]We can perform the operation 94+91=185 so we get:
[tex]x+185=400[/tex]And we can substract 185 from both sides of the equation:
[tex]\begin{gathered} x+185-185=400-185 \\ x=215 \end{gathered}[/tex]Then the answer to part a is 215.
Now that we have the number of seats on the stage level we can find the max amount of money the theater can bring in. This will be given by the total number of seats in the stage level multiplied by the cost per ticket for these seats plus the total number of seats in balconies (185) multiplied by the cost per ticket for these seats. Then we get:
