From the formula given:
A = 150 ft², π ≈ 3.14
r = √(A/π)
r = √(150/π)
r = √(150/3.14) use calculator
r ≈ 6.911
r ≈ 6.9
The tenth digit is 9, and the digit after it is 1, and that is not up to 5, so the 9 is not rounded up to 10, it remains as 9.
Radius is ≈ 6.9 feet to nearest tenth
Hope this helps.

Answer:
$42.93
Step-by-step explanation:
Because you multiply the cost by the percentage
Answer:
The Answer is: y - 8 = 5/3(x - 3)
Step-by-step explanation:
Given the y intercept form:
y = 5/3x + 3
Note that the slope is 5/3.
Find a point on the line.
Choose x = 3, solve for y:
y = 5/3(3) + 3
y = 5 + 3
y = 8
This give you the point:
(3, 8)
Use this to substitute into the point slope equation:
y - y1 = m(x - x1)
y - 8 = 5/3(x - 3)
Isabella will have $6147 after 4years.

What is compound interest?</h3>
Compound interest is the addition of interest to the principal sum of a loan or deposit.
C.I. = Amount - Principle
Amount is given as-
A = P {1 + (r/n)}^(nt)
where A is the final amount
P is the initial principle amount
r is the interest rate
t is the time period elapsed
n is number of times interest applied per time period
Now it is given that
P = $5000
r = 5.3%
n = 1 years, since its annually
t = 4 years
⇒ A = P {1 + (r/n)}^(nt)
⇒ A = 5000 {1 + (5.3/100*1)}^(4*1)
⇒ A = 5000 {1 + (0.053)}^(4)
⇒ A = 5000 {1.053}^(4)
⇒ A = 5000 * 1.23
⇒ A = $6147.28
⇒ A ≈ $6147
Hence,Isabella will have $6147 after 4years.
