Answer:
c > -7/8
Step-by-step explanation:
Add 2 for an inequality that compares to zero:
2x^2 -3x +(c+2) > 0
This will be true when the discriminant is negative. For the quadratic ...
ax^2 +bx +c
the discriminant is ...
b^ -4ac
We want this to be negative:
(-3)^2 -4(2)(c+2) < 0
9 -8(c +2) < 0
9 -8c -16 < 0
-7 < 8c
-7/8 < c
The given inequality will be true for all values of c greater than -7/8.

Step-by-step explanation:
H
Given Information:
Volume of truck = 15 ft³
Area of base of container = 6 ft²
Required Information:
Height of truck = h = ?
Answer:
Height of truck = h = 2.5 ft
Step-by-step explanation:
The volume of the truck is given by
V = l*w*h
Where l is the length, w is the width, h is the height
The area of the base of container is given by
A = l*w
Where l is the length and w is the width.
Substitute the equation of area into the volume of the truck equation.
V = l*w*h
V = (A)*h
Re-arrange for the height,
h = V/A
h = 15 ft³/6 ft²
h = 2.5 ft
Therefore, the height of the clothing truck is 2.5 ft.
