The rectangular floor of a room is 4 feet and 6 inches wide and 8 feet and 3 inches long. How many square yards of floor coverin
1 answer:
148.5 square yards of floor covering will be needed to cover the floor.
Step-by-step explanation:
Width of floor = 4 feet 6 inches
Length of floor = 8 feet 3 inches
As we know,
1 foot = 12 inches
Therefore,
Width of floor = 4(12) + 6 = 54 inches
Length of floor = 8(12) + 3 = 99 inches
Area of floor = Length * Width
36 Inch = 1 yard
1 inch =
5346 inches =
148.5 square yards of floor covering will be needed to cover the floor.

It seems you missed to upload graphs given with the question. So i will draw the graph myself then explain the answer.
f(x)=x^3+8 is the given function which is created from parent function f(x)=x^3
Graph of x^3 is like graph of any odd degree function which starts from bottom and goes to top because of positive leading coefficient.
then there is +8 which means parent function is shifted 8 units upward.
You may directly plug some numbers to find points on f(x)=x^3+8 then join those points to get the graph easily.
like we can use numbers x=-2,-1,0,1,2,...
I will show you calculation for x=-2
f(-2)=(-2)^3+8=(-2)(-2)(-2)+8=-8+8=0
Hence first point is (-2,0)
Similarly you can find more points then use them to find the final graph as shown in attached picture.
