Answer:
A
Step-by-step explanation:
$320 + 4.75% = $15.20 .
$320+$15.20= $335.20
Answer:
h = 1,743
Step-by-step explanation:
Volume of a box is
V(h) = ( A - 2h) * ( B - 2h)* h A = 7 B = 12
We have
V(h) = ( 7 - 2h) * ( 12 - 2h ) * h
V(h) = ( 84 - 14*h - 24*h + 4*h² ) * h
V(h) = ( 84 - 38*h + 4 *h² ) * h ⇒ V(h) = 84h - 38h² + 4h³
Taking derivatives both sides of the equation
V´(h) = 84 - 76h + 12x²
V´(h) = 0 84 - 76h + 12x² = 0 42 - 38h + 6x²
3x² - 19h + 24 = 0
Solving for h h1 = [ ( 19 + √(19)² - 288 ]/ 6 h1 = [ (19 + √73)/6]
h₁ = 4,59 we dismiss this value since 9,18 (4,59*2) > A
h₂ = [ 19 - √73)/6] h₂ = 1,743
h = 1.743 is h value to maximizes V
Originally, the 500 shares were worth 25 bucks a share. If he only made $150 with 500 shares, the shares were worth $0.30 a share. So, subtract $0.30 from $25 to get $24.70. Divide 24.7 by 25 to get 0.988. Multiply this by 100 to change it into a percent. The share price decreased 98.8%.
