We start with the parent function:
[tex]y=\sqrt[]{x}[/tex]The transformations are:
• Shift up 6 units
,• Reflect about the x-axis
,• Reflect about the y-axis
The first transformation is equal to add 6 units to y:
[tex]\begin{gathered} y_2=y+6 \\ y_2=\sqrt[]{x}+6 \end{gathered}[/tex]Then, a reflection across the x-axis makes y change sign, so we will have:
[tex]\begin{gathered} y_3=-y_2 \\ y_3=-\sqrt[]{x}-6 \end{gathered}[/tex]Finally, a reflection across the y-axis makes the argument x change sign, so we will have:
[tex]\begin{gathered} y_4=y_3(-x) \\ y_4=-\sqrt[]{-x}-6 \end{gathered}[/tex]This is the final function.
We can graph this function, and the intermediate steps, as:
Answer: y = -√-x - 6

We are given a rectangle with sides as indicated.
Required;
We are required to find the area and the perimeter from the dimensions provided.
Step-by-step solution;
We shall begin by reconstructing the rectangle and show the missing sides. This is done below;
Take note that we can extract one of the triangles and use the dimensions to calculate the missing side. This is also shown below;
Observe that we now have a triangle with sides 17 units and 16 units.
We draw a perpendicular and we effectively split the triangle into two right angled triangles. We can now solve for the side x using the Pythagoras' theorem.

There are 15 members of the show choir. In how many different ways can you arrange any 8 members in the front row?

For each of those ...
And so on until choosing 8 chairs

.
The eighth chair can be any of 8.
For each of those ...
Number of ways to fill the 8 chairs = (15 x 14 x 13 x 12 x 11 x 10 x 9 x 8) = 259,459,200
But in each group of 8 people you can sit on (8 x 7 x 6 x 5x 4 x 3 x 2 x 1) = 40,320 orders.
So each group of 40,320 people is represented 24 times out of 259,459,200

The area of a circle with radius r is given by the following formula:

[tex]C=2\pi r[/tex]Finding the answerWe are given the area of the circle. With this data and the first formula we can construct an equation for the radius r. Once we find the radius of the circle we can use it to find its circumference. So first of all we take the first formula and we equalize it to 95.03:
[tex]95.03=\pi r^2[/tex]We can divide both sides by π:
[tex]\begin{gathered} \frac{95.03}{\pi}=\frac{\pi r^2}{\pi} \\ r^2=\frac{95.03}{\pi} \end{gathered}[/tex]Now we apply a square root to both sides:
[tex]\begin{gathered} \sqrt{r^2}=\sqrt{\frac{95.03}{\pi}} \\ r=\sqrt{\frac{95.03}{\pi}} \end{gathered}[/tex]And that's the radius of the circle. Then we can use this value in the formula of the circumference C:
[tex]C=2\pi *\sqrt{\frac{95.03}{\pi}}=34.6[/tex]AnswerThen the answer is 34.6 m.

o points earned 21 Sally borrowed $500 to help pay for a car repair. The interest rate is 16% and the length of the loan is 30 months. How much money will Sally owe in total at the end of 30 months? Do not enter any spaces.
Answers
Answer:
$700
Explanation;
Givern the following
Amount borrowed = $500 (Principal)
Rate = 16%
Time = 30months = 30/12 yrs
Get the interest
Interest = PRT/100
Interest = 500*16*30/12*100
Interest = 5*16*30/12
Interest = $200
Amount owed at the end of 30months = Principal + Interest
Amount owed at the end of 30months = $500 + $200
Amount owed at the end of 30months = $700

Consider that the car can go 22 miles on 1 gallon of gas, therefore the amount of gas required for the 377 mile trip is calculated as,
[tex]\frac{377}{22}\approx17.136[/tex]So the car needs 17.136 gallons of gas to complete the trip.
Since the capacity of the tank is 15 gallons, so the driver has to fill the tank two times.
First time for the full 15 gallons refill, and the second tme for the remaining 2.136 galllons fuel refill.
Thus, the driver has to refill the gas tank 2 times, to complete the trip.

Problem 8:

We use the expression:
[tex]t=\frac{\ln (\frac{m}{p})-\ln (\frac{m}{p}-\frac{r}{n})}{n\ln (1+\frac{r}{n})}[/tex]Here, t is the time it will take to pay, m is the maximum he can afford to pay each month, p is the base loan value, r is APR, n is the number of periods. Now we replace:

*We use the following expression:
[tex]V=P(1+n)^t[/tex]Here V is the value to obtain, P is the original amount, n is the interest rate and t is the number of periods, now we replace:
