f(x) = x2 + 2x + 1, g(x) = 11x − 19 x<span>2 </span>+ 2x + 1 = 11x - 19 x2 - 9x + 20 = 0 (x-4)(x-5) = 0 x = 4, 5
The answer for it is 4 at x=-5. You need to take a derivative of you function and set f'(x)=0, then you find critical points. Set those x values into f(x) and take the lowest value.
Answer:
The answer is A. The volumes are the same
Step-by-step explanation:
First you have to determine the area of the cross sections for each of them.
The area of the rectangular cross section will be:
A= 7(6)
A= 21 cm²
The area of the triangular cross section will be:
A= (7)(6)
A= 21 cm²
So, they both share the same area which Cavalieri's Principle said that if two solids of equal height have equal cross-sectional area at every level, then the volume are the same.
A function will not have any repeating x values...it can have repeating y values, just not the x ones
{(0,2),(3,8),(-4,-2),(3,-6),(-1,8),(8,3)}
u would have to remove one of the sets of points that has 3 as its x value....so either remove (3,8) or (3,-6)....because with both of them in there, u have repeating x values
75 is divisible by 3. It equals 25.
I hope this helped!!
