Answer:
This is an geometric sequence because the common ratio is -2.
Step-by-step explanation:
-2*-2=4
4*-2=-8
-8*-2=16
So, as we are seeing that the common ratio is -2, so this is an geometric sequence.
Answer: It is a composite number since it has more factors than just itself and 1.
Step-by-step explanation:
1x20=20
2x10=20
4x5=20
So we can calculate the front porch area by multiplying the sides
(5 ft)(8 ft)=40 ft^2
By doubling the dimensions it could mean one of two things
1. (40 ft^2) * 2 = 80 ft^2 [doubling area]
2. (5*2)(8*2) = 160 ft^2 [doubling dimensions of each side]
Answer:
Step-by-step explanation:
The profit function is:
Where
P is the profit
and
d is the number of units sold
Now, there is a 50% increase in number of units sold, so d will become:
50% = 50/100 = 0.5
d + 0.5d = 1.5d
So, we have to replace "d" with "1.5d" in the function, which makes it:
From the equations shown, last answer choice is correct.
