Answer:
A
Step-by-step explanation:
Given
x² - 16x + 64 = 0 ← left side is a perfect square and factors as
(x - 8)² = 0, thus
x - 8 = 0 ⇒ x = 8 with multiplicity 2
Thus x = 8 is the only solution → A
Answer:
x = 8 base angle = 81 degrees

Answer:
an = -39 -100(n -1)
Step-by-step explanation:
The given sequence can be described by a 3rd degree polynomial.* However, we suspect a typo, and that your intention is to have a formula for the arithmetic sequence ...
-39, -139, -239, -339
This has a first term a1 = -39, and a common difference d = -100.
The model for the explicit formula is ...
an = a1 +d(n -1)
Filling in the given values, the formula you seek is ...
an = -39 -100(n -1)
_____
* That polynomial is ...
an = 50n^3 +350n^2 -800n +461
This gives a sequence that starts ...
-39, -139, -139, -339, -1039, -2539, -5139, -9139, ...
Answer:
70% are propane grills.
Step-by-step explanation:
First, we will find out how many grills are propane. We will add all of the grills that are not propane together.
10 + 5 = 15
And subtract that from the total amount
50 - 15 = 35
Then we will divide the amount of propane grills by the total amount
35 / 50 = 0.7
And multiply that by 100 to get our percentage.
0.7 * 100 = 70
