The a answer is 48% of 50 = is 24
Answer:
$17,280
Step-by-step explanation:
The model for profit (y), in thousands of dollars, as a function of time (x), in years after 1970 is:
The corresponding value of x in 1978 is:
Estimating the profit (in thousands of dollars) in 1978:
Converting it to dollars:
The estimated profit in 1978 is $17,280.
Add 10 to both sides
3x^2 = -5 + 10
Simplify -5 + 10 to 5
3x^2 = 5
Divide both sides by 3
x^2 = 5/3
Take the square root of both sides
x = √5/3
Simplify √5/3 to √5/3
<em>x = ±√5/3</em>
<u>Answer: A. x = ±√5/3</u>
