1. JP Construction is building a rectangular children's wading pool for the local community center. The pool will be 4.5 meters wide. To meet city building code guidelines, the area of the pool must not be larger than 8 square meters. Which inequality represents the possible lengths of the wading pool, where x represents the length of the wading pool in meters?
Answer:
[tex]x\leq 1.78[/tex]
Step-by-step explanation:
We are given that
Width of pool, b=4.5 m
We have to find the inequality which represents the possible lengths of the wading pool.
Let x be the length of wading pool
We know that
Area of rectangle=[tex]length\times breadth[/tex]
According to question
Using the formula
[tex]4.5x\leq 8[/tex]
Divide by 4.5 on both sides we get
[tex]x\leq\frac{8}{4.5}[/tex]
[tex]x\leq 1.78[/tex]

Explain the importance of using the square of the scale factor to calculate the area of a dilated figure
Answer:
2
Step-by-step explanation:
2+2=4 therefore 2x2 also equals 4, 4/2=2.
In mathematics and geometry, a dilation is an enlargement in size or a reduction in size of a mathematical object. We perform a dilation of a square by placing the shape on a coordinate plane and multiplying each of the coordinates of the vertices of the square by the same number, called the scale factor. This can also be achieved by multiplying the lengths of each of the sides of a square by the scale factor.
When we dilate a square by a scale factor of k, its sides increase by a factor of k, its area by [tex]k^{2}[/tex], and its volume by [tex]k^{3}[/tex].
So, this is the importance of using the square of the scale factor to calculate the area of a dilated figure.
What is Square?
Square, in geometry, a plane figure with four equal sides and four right (90°) angles. A square is a special kind of rectangle (an equilateral one) and a special kind of parallelogram (an equilateral and equiangular one).
What is scale factor?
The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.

We perform a dilation of a shape by placing the shape on a coordinate plane and multiplying each of the coordinates of the vertices of the shape by the same number, called the scale factor.
According to question, we have to explain the importance of using the square of the scale factor to calculate the area of a dilated figure.

Given:
The number of alligators in a wildlife is given by the function
[tex]f(x)=3450(1.04)^{x+1}[/tex]
To find:
The average growth rate of change from the 4th year to the 7th year.
Solution:
We have,
[tex]f(x)=3450(1.04)^{x+1}[/tex]
For x=4, we get
[tex]f(4)=3450(1.04)^{4+1}[/tex]
[tex]f(4)=3450(1.04)^{5}[/tex]
[tex]f(4)=4197.4525[/tex]
For x=7, we get
[tex]f(7)=3450(1.04)^{7+1}[/tex]
[tex]f(7)=3450(1.04)^{8}[/tex]
[tex]f(7)=4721.5632[/tex]
Now, the average growth rate of change from the 4th year to the 7th year is
[tex]m=\dfrac{f(7)-f(4)}{7-4}[/tex]
[tex]m=\dfrac{4721.5632-4197.4525}{3}[/tex]
[tex]m=\dfrac{524.1107}{3}[/tex]
[tex]m\approx 174.70[/tex]
Therefore, the average growth rate of the change from the 4th year to the 7th year is 174.70 per year.

*Hana purchased 2 pairs of pants for $26.59 each and a coat for $49. She used a coupon that saved her $10. The sales tax for the purchase was $7.84. How much was the total purchase?
Answer:
$100.02
Step-by-step explanation:
*Sales tax is always applied after the discount/coupon
1. Find how much Hana had spent on pants. Since she had bought 2 pairs of pants, and they are $26.59 each, we would have to multiply 26.59 by 2. So,
26.59 times 2 is 53.18.
Hana spent $53.18 on pants
2. Find how much Hana had spent on a coat. Since she had bought 1 coat, and they are $49.00 each, we would have to multiply 49.00 by 1. So,
49.00 times 1 is 49.
Hanna spent $49 on coats
3. Find how much Hana spent on clothes. Since she spent $53.18 on pants and $49 on coats, we would have to add 53.18 and 49. So,
53.18+49=102.18
Hanna spent $102.18 on clothes
4. Find how much Hana "spent" after using the coupon. Since the problem says the coupon helps Hana save $10, we need to subtract 10 from 102.18(the total amount of money Hana spent on clothes before using the coupon). So,
102.18-10=92.18
Hanna "spent" $92.18 on clothes after using the coupon
5. Find how much was the total purchase. Sales Tax is the amount of money that needs to be added to the price. Since the price is $92.18 and the sales tax is $7.84, we need to add 7.84 to 92.18. So,
7.84+92.18=100.02
The total purchase is $100.02

How long will it take for $3000 to grow to $11,700 at an interest rate of 6.3% if the
interest is compounded continuously? Round the number of years to the nearest
hundredth.
A) 0.83
B) 2160.28
C) 21.60
D) 2.16
Answer:
Step-by-step explanation:
Using A=P(1+r/n)^nt
Where,
P = principal amount (the initial amount you borrow or deposit), in this case $3000
r = annual rate of interest (as a decimal), in this case 0.06
t = number of years the amount is deposited or borrowed for, in this case we don't know it
A = amount of money accumulated after n years, including interest, in this case $21000
n = number of times the interest is compounded per year, in this case 12
This gives us 21,000=3,000(1+0.06/12)^12t
After simplification, 7=(1.005)^12t
By taking the logarithm of both sides,
Log7=Log1.005^12t
12t = Log 7/Log 1.005
12t =390.1545
This gives us 32.5months
