Answer:
V = -48
Step-by-step explanation:
((-15 + v) / -3) = 21
(-15 + v) = -63
v = -63 + 15
v = -48
Answer:
a) x₁ = 14
x₂ = - 6
b) x = 4
c) P(max ) = 4000000 $
Step-by-step explanation:
To find the axis of symmetry we solve the equation
a) -4x² + 32x + 336 = 0
4x² - 32x - 336 = 0 or x² - 8x - 84 = 0
x₁,₂ = [ -b ± √b² -4ac ]/2a
x₁,₂ = [ 8 ±√(64) + 336 ]/2
x₁,₂ = [ 8 ± √400 ]/2
x₁,₂ =( 8 ± 20 )/2
x₁ = 14
x₂ = -6
a) Axis of symmetry must go through the middle point between the roots
x = 4 is the axis of symmetry
c) P = -4x² + 32x + 336
Taking derivatives on both sides of the equation we get
P´(x) = - 8x + 32 ⇒ P´(x) = 0 - 8x + 32
x = 32/8
x = 4 Company has to sell 4 ( 4000 snowboard)
to get a profit :
P = - 4*(4)² + 32*(4) + 336
P(max) = -64 + 128 + 336
P(max) = 400 or 400* 10000 = 4000000
The answer is maybe C lol
Answer:
10th term is 120.555
Step-by-step explanation:
Answer: I wouldn’t be able to make a linear system right now, but it would be better to use Hamster Fun if it were long-term, and Hamster Heaven if it were short-term.
Step-by-step explanation:
HH (Hamster Heaven) charges 20$ plus one a day, and HF (the other) charges 35 plus one a day, so if you went for 80 days for either one:
HH: 20 + (2.50 x 80) =
20+200: 220
HF: 35 + (1 x 80)= 115
If it were for only a day or two, it would be more efficient to use Hamster Heaven.
