Answer:V(x) = 6x³ + 4x² - 12x - 8
Step-by-step explanation:
The shoe box can either be cube shaped or cubiod shaped. The volume of the box is length × breadth × height
Since Area = Length × Breadth
Volume = Area × Height
V(x) = A(x) × H(x)
A(x) = 2x² - 4
H(x) = 3x + 2
V(x) = (2x² - 4)(3x + 2)
V(x) = 6x³ + 4x² - 12x - 8
Answer: 36,000
Step-by-step explanation: I did the math
Answer:
she spent 2 1/3 weeks in total
Step-by-step explanation:
Vertex is highest point
ok so the t value of the vertex of a function in the form
f(x)=at^2+bt+c is
-b/2a
find t value
h(x)=-16t^2+50t+6
a=-16
b=50
-50/(2*-16)=1.5625
round
1.6 seconds
max height
input 1.6 for t and evaluate (for more precice, input 1.5625 for t)
max height is 45 feet
seems to be
b=initial velocity
c=intial height
a=-16
eqation is
h(t)=-16t^2+70t+5
vertex is -70/(2*-16)=2.1875
input for t to get max height
82 feet
answers are
1.6 seconds
45 feet
82 feet
