The function F(x) = −0.005x^2 + 0.8x + 12 models the relationship between a certain vehicle’s speed and the fuel economy, where F(x) is the fuel economy in kilometres per litre and x is the speed of the vehicle in kilometre per hour.
a) Determine the average rate of change in the fuel economy in the interval of speed [60,80].
b) b) Interpret your result.
Answers
a) The average rate of change on that interval is 0.1
b) as we increase the speed in the interval [60, 80], the fuel economy increases at a rate of 0.1
How to find the average rate of change on the given interval?For any function f(x), the average rate of change on an interval (a, b) is given by:
(f(b) - f(a))/(b - a)
In this case, the function is:
F(x) = −0.005x^2 + 0.8x + 12
And the interval is [60, 80]
Then we have:
F(60) = −0.005*60^2 + 0.8*60 + 12 = 42
F(80) = −0.005*80^2 + 0.8*80 + 12 = 44
Then the average rate of change on that interval is:
R = (44 - 42)/(80 - 60) = 0.1
b) What does that rate means?
F(x) relates the fuel economy and x the speed of the vehicle.
This means that as we increase the speed in the interval [60, 80], the fuel economy increases at a rate of 0.1.

Answers
The equation of the profit function P(x) (in dollars) for this commodity is given by P(x) = 300x - 3600
It is given in the problem that,
The total cost function C(x) = 76x + 3600 (in dollars)
Also,
The total revenue function R(x) = 376x (in dollars)
We need to find the equation of the profit function P(x) (in dollars) for this commodity
First we need to understand the following terms
Cost is the price of a commodity which is paid or charged in exchange of something. Example - 1 kg of apple are of 3 Dollars
Revenue, which is determined by multiplying the average sales price by the quantity of units sold, is the money made from regular business operations.
So,
The equation of the profit is given by = Total Revenue - Total Cost
P(x) = R(x) - C(x)
Putting values, we get
P(x) = 376x - (76x + 3600)
P(x) = 376x - 76x - 3600
P(x) = 300x - 3600
Hence, the equation of the profit function P(x) (in dollars) for this commodity is given by P(x) = 300x - 3600

Answers
Step-by-step explanation:
Given that
A real estate company is interested in the ages of home buyers. They examined the ages of thousands of home buyers and found that the mean age was 45 years old, with a standard deviation of 10 years.That these measures are valid for the population of all home buyers.To find
Complete the given statements about the distribution of all ages of home buyers.So, according to the question
We have,
Mean of ages = 45, andStandard deviation = 10We know that,
Chebyshev's Theorem
The smallest percentage of observations that fall within a precise range of current standard deviations from the mean is estimated by Chebyshev's Theorem. There are many different chance distributions that are covered by this theorem. Chebyshev's Inequality is another name for Chebyshev's Theorem.When the distribution is not normal, Chebyshev's Theorem is used. It states that:
Measures are all within 2 standard deviations of the mean in at least 75% of cases.Measures are all within 3 standard deviations of the mean in at least 89% of cases.The percentage of measurements that are within k standard deviations of the mean is represented by an in general:[tex]P = 100(1-\frac{1}{k^2} )[/tex]
Chebyshev's Theorem is used to determine that:
At least 56% of home buyers are between the ages of 30 and 60.At least 75% of home buyers are between the ages of 25 and 65.For the 1sr item, we have to find k at P = 56,
[tex]P = 100(1-\frac{1}{k^2} )[/tex]
[tex]56 = 100(1-\frac{1}{k^2} )[/tex]
0.56 = 1 - [tex]\frac{1}{k^2}[/tex]
[tex]\frac{1}{k^2} = 0.44[/tex]
k² = 1/0.44
k = [tex]\sqrt{\frac{1}{0.44} }[/tex]
k = 1.5
The bounds are, therefore, within 1.5 standard deviations:
45 - 1.5 × 10 = 30 years old.45 + 1.5 × 10 = 65 years old.Ages 25 and 65 are both 2 standard deviations away from the mean, so:
At least 75% of the home buyers' age lie between 25 years and 65 years.Answer:
According to Chebyshev's theorem, at least 56% of the home buyer's ages lie between 30 years and 65 years.According to Chebyshev's theorem, at least what 75% of the home buyers' ages lie between 25 years and 65 years.To learn more about Chebyshev's theorem, please click on the link:

You are the owner of four Taco Bell restaurant locations. You have a business loan with Citizens Bank taken out 60 days ago that is due in 90 days. The amount of the loan is $50,000, and the rate is 9.5% using ordinary interest.
You currently have some excess cash: $35,000. Due to situations beyond your control, you, as the owner, must make an immediate business decision now to pursue only one of these two choices:
1) sending all of the $35,000 to Citizens Bank as a partial payment on your loan, or
2) using the $35,000 to purchase serving supplies such as food containers, cups, and plastic dinnerware for your inventory. This is the last day to take advantage of the opportunity to save some money due to a special discount price that is "10% off" the normal cost of $35,000 for these items.
Consider these calculations:
(a)
How much interest (in $) will you save on this loan if you make the partial payment and don't purchase the additional serving supplies? (Round your answer to two decimal places.)
$
(b)
How much money (in $) will you save if you purchase the serving supplies with the discount and don't make a partial payment on the loan? (Round your answer to two decimal places.)
$
(c)
How much (in $) will you save by purchasing the discounted serving supplies rather than making the partial payment? (Hint: Find the difference between the savings on the supplies found in part (b) and the savings on the loan interest found in part (a). Round your answer to two decimal places.)
$
(d)
What other factors should you consider before making this decision?
Answers
The amount saved by repaying the loan early is $831.25
The amount of discount received by purchasing supplies is $3,500
The net amount saved by purchasing supplies rather than repaying loan is $2,668.75
What is ordinary interest?
Ordinary interest is the interest computation that is based on 360-day a year count rather than 365-day year count, hence, in determining the amount saved by paying $35,000 out of the amount due to Citizens Bank, we time-apportion the interest for 90 days with respect to 360 days not 365 days.
Amount saved in interest=$35,000*9.5%*90/360
Amount saved in interest=$831.25
Using the $35,000 to purchase serving supplies, 10% discount is given off the normal cost of $35,000
Amount saved with discount=10%*$35,000
Amount saved with discount=$3,500
The difference between discount on supplies and interest saved=$3,500-$831.25
The difference between discount on supplies and interest saved=$2,668.75
The other factors to consider before making the final decisions include, the fact the loan is more important than the supplies because the loan relates to the firm's financing rather than operational needs of supplies
Secondly, the amount saved in interest may be more if another loan of $35,000 can be borrowed elsewhere with significant lower interest rates

Answers
Taking into account the definition of Scientific notation, the correct answer is the first option: the total mass of the paperclips in the box is 4.338×10¹ mg.
Scientific notationScientific notation is a quick way to represent a number using powers of base 10.
The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.n is a whole number, which is called an exponent or an order of magnitude. Represents the number of times the point decimal is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.Total mass of the paperclips
In this case, you know that:
The mass of a paperclip is 6.0×10⁻⁴ mg. A box of paperclips has 7.23×10⁴ paperclips.To know the total mass of the paperclips in the box, you must multiply the number of paperclips in the box by the mass of each paperclip:
7.23×10⁴×6.0×10⁻⁴
To multiply numbers in scientific notation, you multiply the numbers that are not powers of 10 (the numbers previously called "a") and add the exponents of 10.
(7.23×6.0)×10⁴⁻⁴= 43.38×10⁰= 4.338×10¹ mg
Finally, the correct answer is the first option: the total mass of the paperclips in the box is 4.338×10¹ mg.

Use this limit to find f′(11) given f(x)=sqrt(x-2)
Answers
Answer: f'(11)=1/6
Step-by-step explanation:
f(x)=sqrt(x-2)
f(x)=(x-2)^1/2
f'(x)=1/2 * (x-2)^(1/2-1)
f'(x)=1/2 * (x-2)^(-1/2)
f'(11)=1/2 * (11-2)^(-1/2)
f'(11)=1/2 * (9)^(-1/2)
f'(11)=1/2 * (9)^(1/2 * (-1))
f'(11)=1/2 * (9^1/2)^(-1)
f'(11)=1/2 * (3)^(-1)
f'(11)=1/2 * 1/3
f'(11)=1*1/(2*3)
f'(11)=1/6
Using the definition of the derivative, we have
[tex]\displaystyle f'(11) = \lim_{x\to11} \frac{\sqrt{x-2} - \sqrt{11-2}}{x - 11} = \lim_{x\to11} \frac{\sqrt{x-2} - 3}{x - 11}[/tex]
Rationalize the numerator.
[tex]\displaystyle \frac{\sqrt{x-2}-3}{x-11} \cdot \frac{\sqrt{x-2}+3}{\sqrt{x-2}+3} = \frac{\left(\sqrt{x-2}\right)^2 - 3^2}{(x-11)\left(\sqrt{x-2}+3\right)} = \frac{x - 11}{(x - 11) \left(\sqrt{x-2} + 3\right)}[/tex]
If [tex]x\neq11[/tex], we can simplify the limit to
[tex]\displaystyle f'(11) = \lim_{x\to11} \frac{x-11}{(x-11)\left(\sqrt{x-2}+3\right)} = \lim_{x\to11} \frac1{\sqrt{x-2} + 3}[/tex]
The function in the remaining limit is continuous at [tex]x=11[/tex], so we end up with
[tex]\displaystyle f'(11) = \frac1{\sqrt{11-2} + 3} = \boxed{\frac16}[/tex]
