Answer:
see attached
Step-by-step explanation:
The pair of inequalities is graphed in the attachment.
The first inequality graphs as a shaded area below the dashed line y=-x+5.
The second inequality graphs as a shaded area below the solid line y=2x-1.
The solution set is the doubly-shaded area below the point where the lines intersect.
Answer:
54 ft^2
Step-by-step explanation:
The area is the product of length and width:
A = LW = (9 ft)(6 ft)
A = 54 ft^2
The area of the floor is 54 square feet.
F(x) = 4.8x
Have to calculate the apothem of the octagon.
That is the altitude of one of the triangles whose base is x and vertex angle is 22.5 degrees. Divide 360 degrees /8 = 45 degrees, then divide by 2 for the altitude angle.
Using the apothem "a" formula for the area,
Area = a^2 P/2 where P is the perimeter which is 8x
Tan 22.5 = (x/2)/a. a = 1.2
Answer: 3/8
ưhen x = 3
