Answer:
The equation of the line is y = -4x + 2
Answer and explanation:
Given : A rectangular frame of uniform depth for a shadow box is to be made from a 36-in. piece of wood.
To find :
a) Write a function to represent the display area in terms of x.
The perimeter of the box is 36 inches.
Let x and y be the length and width of the box.
So,
....(1)
The area of the box is
Substitute y from (1),
The function in terms of x,
b. What dimensions should be used to maximize the display area?
As A is a quadratic function with a negative leading coefficient.
The vertex is the maximum point on the function.
So, the x-coordinate of the vertex is the value of x that will maximize the area.
Here, a=-1 and b=18
Substitute in (1),
The dimension 9 in. by 9 in. should be used maximize the display area.
c) What is the maximum area?
Substitute the value of x in the area,
The maximum area is 81 square inches.
Answer:
C. 1 1/2
Step-by-step explanation:
you could turn 2/3 into 4/6 and that plus 5/6 equals 9/6. Then you turn it into a mixed number which is 1 3/6 and if you simplify that you get 1 1/2
