You do 8000×.25 to get 2000
then add 8000 to 2000 to get 10000
then multiply 10000 by .15 to get 1500
then add 10000 to 1500 to get your answer which is 11500
Answer:
This is impossible.
Step-by-step explanation:
There are no two consecutive numbers that their product is 360.
A = 2/-3 which is -0.6666...
and b= 1/4.
so what you want to do is -0.66666666666 * 2 = -1.33333333333
then you want to do -1.33333333333 + .24 = (-1.093333333) is your answer
Answer:
answer c
Step-by-step explanation:
A because the chicken is worth more than the ground beef which gets rid of most of the answers so your left with A and C its not C because A doesnt equal the number of money spunt
Information about concavity is contained in the second derivative of a function. Given f(x) = ax² + bx + c, we have
f'(x) = 2ax + b
and
f''(x) = 2a
Concavity changes at a function's inflection points, which can occur wherever the second derivative is zero or undefined. In this case, since a ≠ 0, the function's concavity is uniform over its entire domain.
(i) f is concave up when f'' > 0, which occurs when a > 0.
(ii) f is concave down when f'' < 0, and this is the case if a < 0.
In Mathematica, define f by entering
f[x_] := a*x^2 + b*x + c
Then solve for intervals over which the second derivative is positive or negative, respectively, using
Reduce[f''[x] > 0, x]
Reduce[f''[x] < 0, x]
