Answer:
help with what?
Step-by-step explanation:
±1/2. The equation 
has two possible solutions +1/2 and -1/2.
The problem is a quadratic equations and it can be solved using the equation 
.
Ordering the quadratic equation given in the problem, we obtain 
where a = 4, b = 0, and c = -1
Substituting the values
Answer:
the surface area of the larger prism is or about 2.8 times the surface area of the smaller prism.
Answer:
Step-by-step explanation:
The the area of the rectangular pen be A = LW
L is the length
W is the width
Given
A = 3136ft²
3136 = LW..........1
Given the perimeter P = 2L+2W....... 2
From 1; L = 3136/W
Substitute into 2
P = 2(3136/W)+2W
P = 6272/W + 2W
In order to minimize the amount of material needed, then dP/dW = 0
dP/dW = -6272/W² + 2
0 = -6272/W² + 2
6272/W² = 2
cross multiply
6272 = 2W²
W² = 3136
W = √3136
W = 56ft
Since A = LW
3136 = 56L
L = 3136/56
L = 56ft
Hence the dimensions of the rectangular pen that minimize the amount of material needed is 56ft by 56ft
Point slope for will always be y=mx+b
But the problem is, you don’t have the slope..
