D is the answer you are lookin' 4
Go from -2 to zero. Then zero to 3. Think of a line and zero is the middle. It goes 2 to the left and 3 to the right. So, 5 total number of units.
3.75p<=20
divide by 3.75
p < 5 1/3
he can purchase 5 packs of paper
If the perimeter is 26 and the length of one side of the rectangle is 5cm longer than its breadth,
26 - 5 - 5 = 16
16 / 4 = 4 ( rectangle has 4 sides. )
the breadth is 4cm.
so the length must be 4+5=9cm.
Answer:
Square base dimension = 15 inches
Maximum volume = 7200 inches^3
Step-by-step explanation:
V = x^2y ..... eq 1
Let the square base be x and the height y
Oversize formular is given by
Y + 4x = 92
Y= 92 - 4x .....eq 2
Put eq 2 into eq 1
V = x^2 ( 92 - 4x^3)
V= 92x^2 - 4x^3
Using derivatives
V= 184x - 12x^2
V'= 0 = 184x - 12x^2
X(184 -12x)
X=0
X = 184/12 = 15.33 approximately 15 inches
Maximum Volume = V= 92(15)^2 -5(15)^3
V= 92(225) - 4(3475)
V= 20700 - 13500
V= 7200 inches^3
