The current population of Rochester is 211,000 and is decreasing at a rate of 4.1% every ten years. Which function can be used to find the population 30 years from now?
Answer:
211,000(0.97)t
Step-by-step explanation:
Firstly; Write the exponential decay function for this situation.
y = a(1 – r)t Write the formula.
= 211,000(1 – 0.041)t Substitute 1700 for a and 0.03 for r.
= 211,000(0.97)t Simplify.
Next; Find the population in function.
y = 1700 Substitute 12 for t.
≈ 1180 Use a calculator and round to the nearest whole number.
The population in 30 years function will be approximately 211,000(0.97)t.
The total cost to play paintball can be represented by the expression (48x+54). If Rocco and five friends split the cost equally, what is the cost for each person
Answer:
8x + 9
Step-by-step explanation:
The total number of people splitting the cost equally = Rocco and five friends = 6 people
The total cost to play paintball can be represented by the expression (48x+54)
The cost for each person is calculated as: The total cost to play paintball/ Total number of people
= (48x+54)/6
= 48x/6 + 54/6
= 8x + 9
Therefore, the cost for each person is
8x + 9

help m.e please please
Answer:
(-3, -4)
Step-by-step explanation:
The solution is where the two lines intersect. Therefore, the x-coordinate is -3, and the y-coordinate is -4.
Another way to solve this would be to set the to equations equal to each other, so 2x+2 = -4. Therefore, 2x = -6, and x = -3. And from the second equation, y = -4.

If fixed cost of 20 article is 500 and variable cost for each article is 40. Find the total cost function? Also ,find the total cost of 90 articles?
Answer:
Cost function = 40a + 500
Cost of 90 articles = $4,100
Step-by-step explanation:
The fixed cost is $500 and it will.not change regardless of production level.
The Variable cost is $40 and increases by every additional unit produced.
Assume the number of articles produced is a.
Cost function would be:
Total cost = Variable cost * Number of articles + Fixed cost
TC = 40a + 500
Using this, the cost of 90 articles is:
= 40 * 90 + 500
= $4,100

About how much cardboard is needed to make the inner tube for a roll of paper if the
tube has a diameter of 4.5 cm and is 24 cm long?
Answer:
[tex]A=339.42\ cm^2[/tex]
Step-by-step explanation:
The diameter of the roll of paper, d = 4.5 cm
Radius, r = 2.25 cm
Height of the roll of papaer, h = 24 cm
We need to find how much is needed to make the inner tube for a roll of paper. The surface area of a cylinder for inner tube is given by :
[tex]A=2\pi r h\\\\=2\times \dfrac{22}{7}\times 2.25\times 24\\\\=339.42\ cm^2[/tex]
So, the required area is [tex]339.42\ cm^2[/tex].

As she drove down the icy road, Mrs. Campbell slammed on her brakes. Her car did a 360. Explain what happened to Mrs. Campbell's car.
Answer:
Step-by-step explanation:
Her car doing a 360 means that the car turned in a manner akin to going round a full circle. This is because, she was moving on an icy way. Ice have been known to be slippery, and thus, stepping on the brakes unexpectedly would have made the car tilt a bit, which then increased to turning sideways, and an eventually full circle turning. This full circle turning is what is being referred to as 360
