The equation x² − 10x − 11 = 0 that is equivalent to (x – 5)² = 36. Then the correct option is A.
<h3>What is an equivalent expression?</h3>
The equivalent is the expressions that are in different forms but are equal to the same value.
The equation is given below.
x² − 10x − 11 = 0
Then the equation can be written as
x² − 10x + 25 – 25 − 11 = 0
(x – 5)² = 36
Then the correct option is A.

D. how close a measurement is to an accepted value for the measurement
Answer:
<h2>y = 6,000x + 80,000</h2>
Step-by-step explanation:
Givens
- The population increased 6000 people per year. (This is the constant ratio of change, because it offers information about the relation between variables).
- In 1980, the population was 80,000. (This is the initial condition, the population at the beginning of the period, that's why is the y-intercept of the function).
We know that the linear form has an explicit form

Where
is the constant ratio of change and
is the y-intercept. Replacing given values, we have

Therefore, the right answer is B.
Answer:
Jacob's rate of return is <u>19.2%</u>.
Step-by-step explanation:
Given:
Jacob invested $500 in a stock and after a year had $596.
Now, to find the rate of return.
So, we get the amount of return first:
Present value - value before a year = Return.
$596 - $500 = $96.
Now, to get the rate:
Return / Value before a year × 100.



Therefore, Jacob's rate of return is 19.2%.
