Answer: The graph is below
======================================================
Explanation:
If x = 0, then,
g(x) = -x+1
g(0) = -0+1
g(0) = 0+1
g(0) = 1
Therefore, x = 0 leads to y = 1. The point (0,1) is on the g(x) line.
Now try x = 1
g(x) = -x+1
g(1) = -1+1
g(1) = 0
The point (1,0) is also on the g(x) line.
Draw a line through the points (0,1) and (1,0)
Then erase the portion that is to the left of x = -4
This is because g(x) is only graphed when x > -4; i.e. we're only graphing stuff to the right of x = -4.
We'll have an open hole when x = -4 since we aren't including it as part of the graph.

John has $10,000 in debt with Discover, $4,000 in debt with Chase, $9,000 in debt with Citi Bank, and $3,000 in debt with Wells Fargo, giving him a total debt of $26,000. What percentage of John's total debt is with Discover?*
Answers
John holds 26 percent of the debt from discover bank in its total debt obligation.
What is a total debt?The Total debt represents the obligations being taken by a company in the form of debt and yet to be repaid by them to the lender.
Given that the Debt hold in discover bank is $10,000
Total debt: $26,000
Computation of ratio of debt in discover bank:
Debt proportion = Debt hold in discover bank / Total debt
Debt proportion = 10,000/ 26,000
Debt proportion = 26%
Therefore, John holds 26 percent of the debt from discover bank in its total debt obligation.

According to one mathematical model, the average life expenctancy for American men born in 1900 was 55 years. Life expectancy has increased by about 0.2 year for each birth year after 1900. If this trend continues, for which birth year will the average life expentancy be 71 years?
a) Write an equation to model the problem. Let t represent the number of years after 1900 and let n represent men's life expectancy at that time. For example t=12 and n=57.4 in the year 1912.
Answer: ?
b) Solve the equation, then answer the question given above. (Note: You are asked for a year, not a value for t.
Answer: ?
Answers
a) An equation to model the problem of determining the birth year when the average life expectancy will be 71 years is y = 55 + 0.2x.
b) From the equation above, from 1980 or in the 80th birth, the average life expectancy will be 71 years.
What is the average life expectancy?The average life expectancy refers to the average time in years that a person is expected to live after birth.
The average life expectancy has been a statistical tool for understanding a person's lifespan on earth based on some demographics.
What is an equation?An equation is a mathematical statement that equates two or more variables, numbers, or values or regards them as equivalent or equal.
For this situation, we can use the formed equation to predict a person's life expectancy average in the future, given the current years and increasing rate of life expectancy.
Life expectancy in 1900 = 55 years
Life expectancy increase for each birth year after 1900 = 0.2
Life expectancy = y
Year = x
y = 55 + 0.2x ... Equation
71 = 55 + 0.2x

You have a rectangular prism whose cross section is a square with side length

It appears to have 70 cubic centimeters of water in it, but when you submerge the prism into the water, the water level rises to the 115-cubic-centimeter mark. Determine how long your prism is.
Answers
Answer:

Step-by-step explanation:
The volume of the prism is:
V = l × w × h
But we only know the width and height which are both 3cm. See image.
We put it in the calibrated container (container with markings on it) We find out the volume is 45. Because 115 - 70 is 45.
Divide to find the missing length. See image.

If y = -3 cos (2x), then derivative d²y / dx² is 12 cos (2x)
Given,
y = -3 cos (2x)
We have to find derivative d²y / dx²
d²y / dx² = -3 (d² cos x / dx²) = -3 d/dx (d cos 2x / dx)
According to the concept:
d cos x / dx = - sin x
Here,
d cox 2x / dx = - sin 2x
So,
d²y / dx² = (- 3 × 2) d/dx (- sin 2x)
d²y / dx² = -6 (d sin 2x / dx)
d²y / dx² = 2 × 6 cos 2x
d²y / dx² = 12 cos (2x)

how much interest would $1,000 earn in 1 year at an annual rate of 2% compounded annually
Answers
The Compound Interest would be $1104.895
What is Compound Interest ?
The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound and simple interest is this. If we examine our bank statements, we will typically see that our account is credited with interest on a yearly basis. Even though the principal remains the same, the interest changes annually. We can observe that interest rises over time. As a result, we can infer that the interest the bank charges is compound interest, or CI, rather than simple interest.
Number of quarters in 5years =5×4=20
Quarterly rate of compound interest

If a street that is 270 ft long is covered in snow. City workers are using a snowplow to clear the street. The diameter of the tire is: 3.2 meters.
Diameter of the tireFirst step is to determine the circumference of the tire
Circumference of the tire = (270 m / 27)
Circumference of the tire = 10 meters
Second step is to make use of 3.14 for π to determine the diameter of the tire using this formula
Diameter of the tire = Circumference of the tire / π
Let plug in the formula
Diameter of the tire = 10 / 3.14
