Answer:
17
Step-by-step explanation:
Given expression;
(x - 2)² + 8² = x²
To solve this problem, expand the expression in the parentheses;
(x- 2)(x -2) + 64 = x²
( x² - 2x -2x + 4) + 64 = x²
x² - 4x + 4 + 64 = x²
x² - 4x + 68 = x²
Collect like terms;
x² - x² - 4x + 68 = 0
-4x = -68
x =
= 17
We have that
<span>p(t)=-3t^2+18t-4
using a graphing tool, we can see the maximum of the graph
(see the attached figure)
A) </span><span>In what year of operation does Mr. Cash’s business show maximum profit?
</span>
Mr. Cash’s business show maximum profit at year 3 (maximum in the parabole)
<span>B) What is the maximum profit?
23 (hundred of thousand of dollars) = 2.300.000 dollars
</span>c) What time will it be two late?
(This is the time when the graph crosses zero and the profits turn into losses )
5.77 years, or an estimate of about 69 months.
Answer:
Step-by-step explanation:
3x+6=-5-2x-6
+2x. +2x
5x+6= -5-6
5x+6= -11
-6. -6
5x= -17
divide by 5
x= -3.4
