A) 460 ≥9.50h+60
B) the minimum of hours Jessie can work is about 42 hours.
By the size of the cluster for the value.
The solutions or roots to this equation is found by solving for x. We can do this a couple ways either by FOIL or quad formula
3x^2+6x+6=0
3(x^2+2x+2)=0
x^2+2x+2=0 we cant FOIL this out so we use the quad formula
x= [(-b+\-sqrt(b^2-4ac))/2a]
x= -2+\- sqrt(4-4(1)(2))/2(1)
x= -1 +i , -1 - i
So we have complex roots since our quad formula returned a negative number. Whenever the quad formula answer is positive we have two roots/solutions, when it is zero we have one root/solution, and whenever it is negative we have Complex roots/solutions
Hope this helps. Any questions please just ask. Thank you.
F(h)= 20 +25h
next plug in the hours but first you need to take the minutes and transfer them to hours
120 minutes = 2 hours
so you plug in 20 + 25(2)
that equals 70
therefor your answers are
f(h)= 20 +25h
and
$70
Luis is wrong because 8 to the third power is not 24, but is 512. He multiplied 8 by 3 instead of doing 8x8x8, so Luis made an incorrect claim.
