Answer:
m(x) = 20000(0.97)^x
Step-by-step explanation:
Given that :
Initial population, population in 1990, P = 20,000
Rate, r = 3% = 0.03
Number of visitors to the museum x years after 1990
Since population decreases, Decay formula
m(x) = Initial population * (1 - r)^x
m(x) = 20000(1 - 0.03)^x
m(x) = 20000(0.97)^x
25%=25/100
5=25/100*(number she wants to build)
(Number she wants to build)=5/25*100=5*4=20
Answer:
x intercept:
5
y intercept: 50
Step-by-step explanation:
- let us plot the graph for better understanding.
- we will represent f(x) on y-axis so, the equation will become: y= 50-10x
- the equation is of the form : y=mx+c
[where, m: slope of the line
c : y-intercept ]
- meaning of x intercept: the x-coordinate of the point where the line meets x-axis
-
meaning of y intercept: the y-coordinate of the point where the line meets y-axis
- the line y= 50-10x has slope of -10 and it passes through (0,50)
[ (0,50) lies on the line only. substitute and check if the point satisfies the above line equation]
- by seeing the graph in the attachment and by the definitions given above, we can say that,
x intercept: 5
y intercept: 50
Answer:
4 miles per gallon of fuel.
Step-by-step explanation:
The fuel efficiency of a car is given by the ratio of distance traveled by car to the volume of fuel used.
Now, given that Nate's car will go 20 miles on 5 gallons of fuel.
Therefore, the fuel efficiency of Nate's car will be given by the ratio
=
=
= 4 miles per gallon of fuel. (Answer)
