Answer: The correct option is (a) [tex]2x^2+3x-5.[/tex]
Step-by-step explanation: We are given to find the quotient in the following division :
[tex]Q=\dfrac{2x^3-3x^2-14x+15}{x-3}.[/tex]
To find the quotient, first we will try to factorize the numerator and then we will try to divide by the denominator.
We have
[tex]Q\\\\\\=\dfrac{2x^3-3x^2-14x+15}{x-3}\\\\\\=\dfrac{2x(x-3)+3x(x-3)-5(x-3)}{x-3}\\\\\\=\dfrac{(x-3)(2x^2+3x-5)}{(x-3)}\\\\=2x^2+3x-5.[/tex]
Thus, the required coefficient is [tex]2x^2+3x-5.[/tex]

How can you use transformations to graph this function? y=3.7^{-x}+2 Explain your steps
Answer:
Steps are explained in the explanation part and graph is attached below.
Step-by-step explanation:
We have to graph the function [tex]y=3.7^{-x}+2[/tex] using the rule for transformation.
Let us suppose the parent function is [tex]y=3.7^x[/tex]. Below, is the graph of the parent function (fig 1)
When we add some constant 'c' in the function then the graph of the parent function shifts upward by 'c' units.
Hence, when we add 2 then the parent function will get shifted upward by 2 units. The graph of [tex]y=3.7^{x}+2[/tex] is attached below (fig 2)
Finally, x is replaced by -x hence the graph is reflected about y axis.
In figure 3 the graph of the given function is shown.
The graph of the function [tex]y = 3.7^{-x}+2[/tex] can be draw by using transformations. First shift the graph of [tex]y = 3.7^{x}[/tex] upwards by 2 units and then replace x by -x in the function [tex]y = 3.7^x+2[/tex] and graph of the function [tex]y = 3.7^x+2[/tex] is reflected about y-axis.
Given :
[tex]y = 3.7^{-x}+2[/tex]
To graph the above function using transformations following steps can be use:
Step 1 - Draw the graph of exponential function [tex]y = 3.7^{x}[/tex].
Step 2 - Now, shift the graph upwards in y axis by 2 units. The resulting graph is of function [tex]y = 3.7^x+2[/tex].
Step 3 - Now, replace x with -x in the function [tex]y = 3.7^x+2[/tex] and graph of the function [tex]y = 3.7^x+2[/tex] is reflected about y-axis. The resulting graph is of the function [tex]y = 3.7^{-x}+2[/tex] .

A certain store is advertising this deal: “Rent a TV for only $10.50 a week.” How much is this a year? (There are 52 weeks in a year.)
Answer:
Rent of a TV for one year would be $546.
Step-by-step explanation:
A certain store is advertising this deal :
"Rent a TV for only $10.50 a week."
We have to calculate the rent for a year.
As we know there are 52 weeks in a year.
∵ Rent of a TV for one week = $10.50
∴ Rent of a TV for one year = 10.50 × 52
= $546.00
Rent of a TV for one year would be $546.

Therefore, correct option is:
A parallel line to a given line through a point not on the line.Answer:
Option 1 is correct. The line created will be parallel to the given line and passing through a point not on the given line.
Step-by-step explanation:
In the given image, firstly a line is constructed.
After drawing the line, an intersecting line is drawn. Now, the measure of angle between these two lines is calculated.
After calculating the measure of angle, an angle of same measure is created at a point not on the first line.
Then, a line is drawn passing through that point with the same angle measure.
The created line will now be parallel to the first line because the corresponding angles are equal.
Therefore, option 1 is correct. The line created will be parallel to the given line and passing through a point not on the given line.

A clock gains 0.020 s/min. how many seconds will the clock gain in exactly six months, assuming 30 days are in each month
Final answer:
To calculate the total seconds a clock gains in six months, we multiply the number of minutes in six months by the gain per minute, resulting in a total of 5,184 seconds gained.
Explanation:
The question asks us to determine how many seconds a clock gains over a six-month period, assuming each month has 30 days. The clock gains 0.020 seconds per minute.
To find the total seconds gained, we need to calculate the number of minutes in six months and then multiply that by the gain per minute. There are 60 minutes in an hour, 24 hours in a day, and the problem assumes 30 days in a month. Over six months, this totals:
60 minutes/hour × 24 hours/day × 30 days/month × 6 months = 259,200 minutesNow, multiply the total minutes by the gain per minute:
259,200 minutes × 0.020 seconds/minute = 5,184 secondsTherefore, the clock will gain a total of 5,184 seconds over a six-month period assuming each month has 30 days.

Pablo's goal is to have 5000 after 4 years is this possible if he invest with a rate of return of 6%
To achieve a future value of $5000 after 4 years with a 6% rate of return, Pablo would need to invest an initial amount.
Explanation:To calculate the future value of an investment with a given rate of return, you can use the formula:
FV = PV * (1 + r)ⁿ
Where FV is the future value, PV is the present value, r is the rate of return expressed as a decimal, and n is the number of years.
In this case, Pablo wants to have $5000 after 4 years with a 6% rate of return. Assuming he doesn't invest any initial amount, we can substitute these values into the formula:
FV = $0 * (1 + 0.06)⁴
FV = $0 * 1.262476
FV = $0
Based on the calculation, it is not possible for Pablo to have $5000 after 4 years with a 6% rate of return if he doesn't invest any initial amount.

b. $54.60
c. $79.00
Answer:
Mark up: $15.6 (option b)
Selling Price: $54.6 (option b)
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
A skateboard costing $39.00 marked up 40% on cost.
To calculate the markup we have to multiply the skateboard cost (39) by the percentage in decimal form (40/100= 0.4)
39 x 0.4 =15.6
Mark up: $15.6 (option b)
For the selling price we have to sum the cost and the markup:
15.6 + 39 = 54.6
Selling Price: $54.6 (option b)
