Answer:
yes
Step-by-step explanation:
A quadratic function has the general form
fx) = ax² + bx + c ( a ≠ 0 )
f(x) = x² - 2x + 3 ← is in this form and is a quadratic function
The first term is -43.
Explanation:
an = a + (n - 1)d
a12 = a + 11d = 56, first equation
a21 = a + 20d = 101, second equation
Subtract the second equation from the first equation, cancelling +a and -a
11d - 20d = 56 - 101
-9d = -45
d = 5
Subtitute d into the first equation
a + 99 = 56
a = -43
a refers to the first term, hence the first term is -43.
Multiply (or distribute) the exponent<span> outside the parenthesis with every </span>exponent<span>inside the parenthesis, remember that if there is no </span>exponent<span> shown, then the </span>exponent<span> is 1. Step 3: Apply the </span>Negative Exponent<span> Rule. </span>Negative exponents<span> in the numerator get moved to the denominator and become positive </span>exponents<span>.</span>

Answer: A. profit of $4500
<u>Step-by-step explanation:</u>
r(x) = x² + 6x + 10
- <u>c(x) = x² - 4x + 5</u>
(r - c)(x) = 10x + 5
(r - c)(4) = 10(4) + 5
= 40 + 5
= 45
(r - c)(x) represents the profit (in hundreds of dollars) in x months
(r - c)(4) represents the profit (in hundreds of dollars) in 4 months
So, the new store will have a profit of $4500 in 4 months
