HELPPPPPP give linear function for total remaining oil reserves
A) R = -19t + 1890 B) 11 years from now, the total oil reserves will be 1681 billions of barrels. C) The world's oil reserves will be completely depleted (all used up) approximately 99.47 years from now.
Describe Linear equation?The slope of a line represents the rate of change between the x and y variables, or the rise over the run. A positive slope means that the line is increasing from left to right, while a negative slope means that the line is decreasing from left to right. A slope of zero means that the line is horizontal, while an undefined slope means that the line is vertical.
A) The rate of decrease in oil reserves is 19 billion barrels per year, which can be represented as a slope of -19. The initial oil reserves are 1890 billion barrels, which is the y-intercept. Therefore, the linear equation for the total remaining oil reserves R, in terms of t (the number of years since now) is:
R = -19t + 1890
B) To find the total oil reserves 11 years from now, we can substitute t = 11 into the equation:
R = -19(11) + 1890
R = -209 + 1890
R = 1681 billion barrels
Therefore, 11 years from now, the total oil reserves will be 1681 billions of barrels.
C) If no other oil is deposited into the reserves, the reserves will be completely depleted when R = 0. We can use the linear equation to find how long it will take for the reserves to reach 0:
0 = -19t + 1890
19t = 1890
t = 99.47 years
Therefore, the world's oil reserves will be completely depleted (all used up) approximately 99.47 years from now, assuming no new reserves are discovered or added.

Katie and Jill currently share a dresser, and each would like to have one of her own. As a valued member at the local furniture store, you receive an additional discount off each purchase. Calculate the amount of discount off each item.
With the discount, each dresser would cost $450.
What is the discount?
A discount is a reduction in the price of a product or service that is offered by a seller to a buyer. It is a form of incentive that is used to encourage customers to purchase goods or services, often by making them more affordable or attractive.
To calculate the amount of discount off each item, we need to know the original price of each dresser and the percentage discount that is being offered. Let's assume that the original price of each dresser is $500, and the discount being offered is 10%.
To calculate the discount off each item, we can use the following formula:
Discount amount = Original price x Discount rate
where the discount rate is the percentage discount expressed as a decimal (e.g., 10% = 0.1).
So, for each dresser, the discount amount would be:
Discount amount = $500 x 0.1 = $50
Therefore, each dresser would be discounted by $50. This means that the new price for each dresser would be:
New price = Original price - Discount amount
New price = $500 - $50 = $450
Hence, with the discount, each dresser would cost $450.

This question is from my linear algebra class:
Suppose u and w are unital orthogonal vectors. Show that || u - w || = [tex]\sqrt{2}[/tex]
Step-by-step explanation:
Since u and w are orthogonal, their dot product is 0. Thus,
u · w = 0
Using the Pythagorean Theorem,
||u - w||^2 = ||u||^2 + ||w||^2 - 2(u · w)
Since u and w are unital (i.e., their lengths are 1), we have
||u||^2 = ||w||^2 = 1
Substituting these values and u · w = 0, we get
||u - w||^2 = 1 + 1 - 0 = 2
Taking the square root of both sides, we get
||u - w|| = √2
Therefore, we have shown that if u and w are unital orthogonal vectors, then ||u - w|| = √2.

Think a moment about factoring a polynomial by finding the GCF.
Explain the role of the GCF in factoring a polynomial.
Where is the GCF placed after factoring out the GCF?
How do you verify factoring is correct?
The role of GCF, its placement and verification has been explained below. The solution has been obtained by using the concept of Greatest Common Factor.
What is Greatest Common Factor?The greatest common factor, or largest number, is the product of two or more numbers (GCF). The greatest number (factor) that separates them yields a natural number.
1. The GCF is a factor that all terms in a polynomial share.
For instance, if the polynomial has the form R * S + R * T, the GCF is R because both terms share the factor R.
2. The GCF is positioned in front of the remaining polynomials, outside of the parenthesis, once we have factored out the GCF.
R * S + R * T, given the prior example, is R (S + T).
3. By allocating the GCF to the polynomial enclosed in parenthesis, we can verify that our factoring is accurate.
Hence, the above stated is the role of GCF in factoring a polynomial.

Shape A is reflected in the line with equation x = 2 to give shape B. Shape B is reflected in the line with equation x = 6 to give shape C. Describe fully the single transformation that maps shape A onto shape C.
The single transformation that maps shape A onto shape C is a translation of 4 units to the right.
What is single transformation?A single transformation is a mathematical operation that changes the position, orientation, or size of a geometric figure. It can be a translation, reflection, rotation, or dilation. It is a way to describe how a figure is transformed to obtain a new figure.
To map shape A onto shape C, we need to perform a sequence of transformations.
First, shape A is reflected in the line x = 2 to give shape B. This is a reflection in the vertical line passing through x = 2.
Next, shape B is reflected in the line x = 6 to give shape C. This is a reflection in the vertical line passing through x = 6.
To find the single transformation that maps shape A onto shape C, we can combine these two reflections into a single transformation.
The composition of two reflections in vertical lines is a translation.
In this case, the distance between the vertical lines x = 2 and x = 6 is 4 units. Since shape A is reflected in the first vertical line and shape C is reflected in the second vertical line, the movement is from the first line to the second line, which is to the right.

A bank is offering you a mortgage on a house that costs $250,000. The down payment is 3% of the purchase price and the closing costs are another 3%. The interest rate is 5.5% and the loan term is 30 years.
What amount of money do you need to save to purchase the home (down
payment + closing costs)?
What is the total amount the bank will be loaning you?
What do you expect your monthly payments to be?
Amount of money do you need to save to purchase the home is $15,000. The total amount the bank will be loaning you is $235,000. You can expect to pay around $1,332.29 per month.
Describe Down Payment?A down payment is a payment made upfront when purchasing a large ticket item, such as a home or a car. It is a percentage of the total purchase price that the buyer pays out of their own pocket, with the remainder of the price financed through a loan.
To calculate the down payment, we need to multiply the purchase price by the percentage:
Down payment = 0.03 x $250,000 = $7,500
To calculate the closing costs, we also need to multiply the purchase price by the percentage:
Closing costs = 0.03 x $250,000 = $7,500
So the total amount of money needed to purchase the home is the sum of the down payment and the closing costs:
Total cost = $7,500 + $7,500 = $15,000
The amount the bank will be loaning you is the purchase price minus the down payment and the closing costs:
Loan amount = $250,000 - $15,000 = $235,000
To calculate the monthly payments, we need to use the formula for a fixed-rate mortgage:
M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ⁻¹]
where:
M = monthly payment
P = loan amount
i = monthly interest rate (5.5% / 12 = 0.0045833)
n = total number of payments (30 years x 12 months = 360)
Plugging in the numbers, we get:
M = $235,000 [ 0.0045833(1 + 0.0045833)³⁶⁰ ] / [ (1 + 0.0045833)³⁶⁰ – 1]
M ≈ $1,332.29
So you can expect to pay around $1,332.29 per month for 30 years to pay off the mortgage.

Comparing the exponent across the equal sign we get,
a = 6
b = 8
z = 9
Thus, the required value of exponent a, b, and c are 6, 8, and 9 respectively.

I bought my daughter 2 guppy fish for her birthday. Guppy populations grow at a rate of 1700% per month.
Write a formula that models the population of guppies and find the number of guppies I will have in 4 months.
Answer:
2x(1700%x4)+2=138
Step-by-step explanation:
2x2.00=4 2x17=34 34 per month plus the 2 that they already had. 34x4=136 there will be 136 plus 2 after the 4 months
