The correct answer is D.
As you can see, the exponential function grows by doubling the previous output with each increment of the input: start with 1, you double it to get 2, then you double it to get 4, 8 and so on.
On the other hand, the linear function adds 7 with each step. This means that the exponential function will eventually reach and pass the linear one, and will definitely be grater from that point on. In fact, if we continue the table, we get
and you can see how the exponential growth is much faster than the linear one.
Answer:
Part a) The area of the actual floor is
Part b) The ratio of the area in the drawing to the actual area is
Step-by-step explanation:
we know that
The scale drawing is
step 1
Find the dimensions of the square on a scale drawing
The area of a square is equal to
where
b is the length side of the square
so
step 2
Find the dimensions of the actual floor
Divide the length of the floor on the drawing by the scale drawing
step 3
Find the area of the actual floor
The area of a square is equal to
substitute
step 4
Find the ratio of the area in the drawing to the actual area
Simplify
Divide by 64 both numerator and denominator
