Using a graphing calculator you can find that the maximum is 1038, so the profit starts to decline at the t value for <span>1038</span>, which is 31
Answer:
x = 3
Step-by-step explanation:

Square both sides of the equation


(x - 3)(x - 5) = 0
x = 3 or 5
Now, you must always check your results because a result may not satisfy the original equation.
If x = 3, then
and 3 - x = 3 - 3 = 0
So 3 satisfies the original.
If x = 5, then
, but 3 - x = 3 - 5 = -2. Therefore, 5 does NOT satisfy the original equation.
That means that x = 3 is the solution to the equation.
Answer:
0.1785
Step-by-step explanation:
The first one is the bottom right multiply 7.50*h or the hours to find the cost
and the second one is bottom left you start at 0 and advance 0 the multiply or add 67*2=134 then 67*5=335 and then 67*9=603 so you have your numbers 0,134,335,603
