Answer: x = {1, 2}
<u>Step-by-step explanation:</u>
x⁶ - 9x³ + 8 = 0
Let u = x³
⇒ (x³)² - 9(x³)¹ + 8(x³)⁰ = 0
⇒ u² - 9u + 8 = 0
⇒ (u - 1)(u - 8) = 0
⇒ u = 1 or u = 8
Replace u with x³
x³ = 1 or x³ = 8
Take the cubed root of each side
x = 1 or x = 2

Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².
π≈3.14
A. C=πd
Simply plug in the numbers into the formula.
Diameter=Radius*2
17*2=34
C=34(π)
B. (π)(5²)
Plug in the numbers into the formula. Remember that half of the diameter is the radius.
C. (π)(4.5)
There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.
The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.
D. (π)(6.5²)
Remember that the formula for calculating the area of a circle is πr².
Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.
(π)(6.5²)
Therefore, the last answer choice is the correct answer.
A box plot contains two dots placed at the ends of the data for the mininum and the maximum value with a line placed over the median.
Let's put the numbers in your set in order from low to high:
5
6
7
8
9
9
9
10
12
14
17
17
18
19
19
The median is the middle number. We have 15 numbers so we select the 8th number - 7 from each end. In this set, 10 is the median.
Only one box plot has dots at 5 and 19 and a median of 10 - choice B. Thus, B is the proper box plot.
