Answer:
B. -3 ≤ y ≤ 9
Step-by-step explanation:
The range is the vertical extent of the graph. This graph extends from a minimum of y=-3 to a maximum of y=9. Then the range is ...
-3 ≤ y 9 . . . . matches choice B
Answer:
The population in 2011 will be of 34.88 million people.
Step-by-step explanation:
The population after t years is modeled by an exponential function is the following format:
In which P(0) is the initial population and r is the growth rate.
At the beginning of 1990, 21.7 million people lived in the metropolitan area of a particular city.
This means that
The 1998 population was 26 million.
1998 is 8 years after 1990. So
We use this to find the value of r.
So
If this trend continues, how large will the population be in the year 2011?
2011 is 21 years after 1990. So this is P(21).
The population in 2011 will be of 34.88 million people.
Answer:
84
Step-by-step explanation:
Given,
Length of the print(l) = 24 inches
Width of the print(b) = 18 inches
Perimeter of the print(P)= ?
We know,
Perimeter of the print(P) = 2(l + b)
= 2(24 + 18)
= 2(42)
=84 inches^2

Answer:
see below
Step-by-step explanation:
Let x be the original price
x* discount rate = discount
x * 60% = 30
Change to decimal form
x * .60 = 30
Divide each side by .60
x = 30/.60
x =50
The original price was 50 dollars
