ANSWER
The point slope form is
EXPLANATION
The point slope form of the equation of a straight line is given by the formula;
.
Where is the slope of the straight line and the point lies on the line.
We were given the slope to be . This means that .
We were also given that the point lies on the line.
We substitute all these values in to the above equation to obtain,
This simplifies to
The correct answer is C
Answer:
2 feet 4 inches
Step-by-step explanation:
2 inches per day
a foot is 12 inches
6 days would be a foot
so 12 days would be 2 feet
plus the 2 extra days would add up to 2 foot 4 inches
Answer:
<h2>b)4</h2>
Step-by-step explanation:
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
