A city's population increases by 5% every year. If its population today is 300,000, write a function that models the population after x years.
Answer:
f(x) = 300,000(1.05)^x
Step-by-step explanation:
Use the exponential growth equation:
f(x) = a(1 + r)^x
Plug in 300,000 as a, since it is the original population:
f(x) = 300,000(1 + r)^x
The city's population is growing at 5% each year, so plug in 0.05 as r:
f(x) = 300,000(1 + 0.05)^x
f(x) = 300,000(1.05)^x
So, the function for the population growth is f(x) = 300,000(1.05)^x
Find the median of the following numbers:
95, 113, 95, 105, 86, 122
Answer:
100
Step-by-step explanation:
First, order the numbers from least to greatest.
86, 95, 95, 105, 113, 122
Second, look for the middles numbers, if you have an even amount of numbers you will have to find the mean of the two middle numbers.
86, 95, 95, 105, 113, 122
Thirdly, add 95 and 105 together and then divide by two because two is the total amount of numbers you have.
(95 + 105) / 2 = 100.
So the median is 100

Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 1, 3 ]
f(b) = f(3) = - 8 ← from graph point (3, - 8 )
f(a) = f(1) = 0 ← from graph point (1, 0 )
Then
average rate of change = [tex]\frac{-8-0}{3-1}[/tex] = [tex]\frac{-8}{2}[/tex] = - 4 → C
A model train is 9 centimeters long. The actual engine is 18 meters long. What is the scale of the model? Tracy has a model train set that is 59 centimeters long. How long would the train be in real life?
Answer:
1 cm : 2m
1 cm = 2m
118m
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
18 / 9 = 2 : 1
59 x 2 = 118
I’m trying to get this math test done, can I please have some help?
Answer: B
Step-by-step explanation:
If you use slope-intercept form, you can see that B uses the equation y = 5x - 4, and you can also see that it is linear since it is proportional. The only coordinate plane that has a nonlinear line is D.
Solve for x. Please highlight your final answer.

The path of a flying fish as it made its approach to the surface of the ocean and flew out of the water is represented by the quadratic function h(t) = -t2 + 6t - 5, where t represents the time, in seconds, and h(t) represents the fish's height and depth, in feet. Graph the function using the graphing calculator. To the nearest second, how long was the fish out of the water?
1 second
3 seconds
4 seconds
5 seconds
Answer:
4 seconds
Step-by-step explanation:
fish broke the water's surface in 1 second and went back into the water at 5 seconds
∴ it was out of the water for 4 seconds

You must show all your working.
9 cm

S
Answer:
The answer is below
Step-by-step explanation:
PQRS is a rectangle. The length of rectangle PQRS = 9 cm + b cm = (9 + b)cm
The breadth of PQRS = a. Hence:
Area of PQRS = length * breadth = (9 + b)(a) = 9a + ab
but Area of PQRS = 84 cm²
9a + ab = 84 (1)
In rectangle PXYS, length = QR = a cm, breadth = YS = b cm
Hence area of PXYS = length * breadth = (a)(b) = ab
But Area of PXYS = 21 cm²
ab = 21 (2)
substitute ab = 21 in equation 1:
9a + 21 = 84
9a = 84 - 21
9a = 63
a = 7 cm
ab = 21
7b = 21
b = 3 cm
Therefore a = 7cm, b = 3 cm

The distance from Alison's house to the mailbox is 2/5 mile. The distance from the mailbox to the bus stop is 1/3 mile. What is the total distance from Alison's house to the bus stop? 3/15 11/15 5/6 3/8
Answer:
Option B is correct
Step-by-step explanation:
Given
Distance from Alison's house to the mailbox = [tex]\frac{2}{5}[/tex] miles
Distance from the mailbox to the bus stop [tex]\frac{1}{3}[/tex] miles
The total distance between Alison's house to the bus stop is
[tex]\frac{2}{5} + \frac{1}{3} \\\frac{6+5}{15} \\\frac{11}{15}[/tex]
Hence, option B is correct
A person wants to purchase a pair of shoes and some pairs of socks. He has less than $121 to
spend. If a pair of shoes costs $30 and each pair of socks costs $8, what is the maximum
number of pairs of socks he can purchase?
the answer is 11
first you need to subtract 30 from 121 since you want one pair of shoes
then to know how many socks you can have divide 91 (the result) and 8 (the price of the socks)
and you can only buy 11
(the more detailed answer is 11.375)
