The area of the composite figure is A = 135 cm²
Given data ,
Let the figure consists of a rectangle and quarter circle
where the area of the rectangle is R and area of quarter circle is C
And , A = R + C
Area of rectangle A = 20 x 2 = 40 cm²
And , area of quarter circle C = ( 1/4 )π ( 11 )²
C = 95.033 cm²
So , A = 95 + 40
A = 135 cm²

The brightness of illumination, l, of an object varies inversely as the square of its distance , d, from the source of illumination, if l = 18 luxes when d= 4m, find l if d =3m
Answers
The value of source of illumination (I) is 32 luxes when the distance d = 4 m.
The brightness of illumination that is denoted by I of ab object varies inversely as the square of of its distance which is denoted by variable 'd'.
So, I ∝ 1/d²
Therefore, I = k/d².......... (i), where k is a non zero proportionality constant.
It is given that if the source of illumination I = 18 luxes when d = 4 m.
Substituting I = 18 and d = 4 in the equation (i) we get,
18 = k/4²
k/16 = 18
k = 18*16 = 288
Now we have to find the value of I when d = 3m.
Now the relation becomes. I = 288/d²
Substituting the value d = 3 in equation (ii) we get,
I = 288/3² = 288/9 = 32 Iuxes.
Hence the source of illumination now is 32 Iuxes.

Fatima lowered the setting of her aircon from 28.6 degrees Celsius to 28.6 - 3.5 = 25.1 degree Celsius at 11:30 am.
After an hour, she set it to 19 degrees Celsius, so she lowered the setting down by 25.1 - 19 = 6.1 degrees Celsius.
To get the answer, we simply subtracted the final temperature (19 degree Celsius) from the temperature at 11:30 am (25.1 degrees Celsius) to find the difference, which is the amount that the setting was lowered.

Given the relation {(−3,−1),(x,0),(5,4),(6,13)} , which value for x would make the relation NOT a function?
Answers
There is no value of x that would make the relation not a function.
What is function?The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h.
To determine whether the relation is a function or not, we need to check if there are any repeated x values with different y values. If there are, then the relation is not a function.
So, if we substitute each x value in the relation, we get:
When x = -3, the y value is -1.When x = x, we don't know the y value yet.When x = 5, the y value is 4.When x = 6, the y value is 13.Since we don't know the y value for x, there is no repeated x value with different y values. Therefore, the relation is a function for any value of x, including x.

How to solve. If the loan agency requires a down payment of 20%, what will your down payment be? If the selling price is 437,250?
Answers
The down payment that will be required if the selling price is $437,250 is 87,450
According to the question,
Down payment = 20%
Selling price = $437,250
The down price can be calculated by calculating 20% of the selling price. This can be done as follows:
We convert the percent into decimal form, this can be done by dividing the percent by 100
Thus the value of a 20% downpayment is 0.20
Then we multiply the decimal by the selling price and get the down payment.
Down payment = 0.20 * 437,250
= 87,450

Suppose that diameters of a new species of apple have a bell-shaped distribution with a mean of 7.26cm and a standard deviation of 0.43cm. Using the empirical rule, what percentage of the apples have diameters that are less than 8.12cm?
Answers
Answer:
95%
Step-by-step explanation:
Upper limit = 8.09 cm
Lower limit = 6.41 cm
Distribution mean = 7.25 cm
Standard deviation = 0.42 cm
The number of standard deviations from the mean of the upper and lower limits are, respectively:
Both limits are two standard deviations away from the mean.
According to the empirical rule, in normal distributions, 95% of the data falls within two standard deviations of the mean. Therefore, 95% of the apples have diameters that are between 6.41cm and 8.09 cm.

The Phi Theta Kappa honor society is holding a raffle to raise funds for a service project. They are selling raffle tickets for $5 each and the prizes are as follows: A Thanksgiving dinner for four valued at $120, four pumpkin pies from the culinary school valued at $25 each, and ten turkey sandwiches for the Monday after break, valued at $6 each. PTK ends up selling 122 tickets total. If someone gives you one of those 122 tickets without your having to pay for it, what is the expected value of
the ticket?
Answers
The expected value of the raffle ticket is $0.98.
How to determine the expected value of the ticketLet's first calculate the probability of winning each prize.
Thanksgiving dinner: There is only one prize, so the probability of winning is 1/122.
Pumpkin pies: There are four prizes, so the probability of winning is 4/122.
Turkey sandwiches: There are ten prizes, so the probability of winning is 10/122.
Now, let's calculate the expected value:
Expected value = (probability of winning Thanksgiving dinner * value of Thanksgiving dinner) + (probability of winning pumpkin pie * value of pumpkin pie) + (probability of winning turkey sandwich * value of turkey sandwich)
Expected value = (1/122 * 120) + (4/122 * 25) + (10/122 * 6)
Expected value = 0.98
Therefore, the expected value of the raffle ticket is $0.98.

An electronics store sells about 80 drones per month for $120
each. For each $6 decrease in price, the store expects to sell eight more drones. The
revenue from drone sales is given by the function R(n) = (unit price) (units sold), or
R(n): = (120 - 6n) (80 +8n), where n is the number of $6 price decreases.
a. How much should the store charge to maximize monthly revenue?
The store should charge $__
b. Using a different revenue model, the store expects to sell five more drones for each
$4 decrease in price. Which revenue model results in a greater maximum monthly
revenue?
The _____ revenue model results in a greater maximum monthly revenue.
Answers
a. The store should charge $90
b. The first revenue model results in a greater maximum monthly revenue.
How to solve for the revenuea. We have
R(n) = (120 - 6n)(80 + 8n)
using product ruile
δr/δn = (120 - 6n)(8) + (80 + 8n)(-6)
δr/δn = 960 - 48n - 480 - 48n
δr/δn = -96n + 480
Now, we set the derivative to zero and solve for n:
0 = -96n + 480
96n = 480
n = 5
we put n as 5 in the equation
120 - 6x 5
= 120 - 30
= 90
To maximize the revenue then $90 is charged.
b. For the 4 dollar decrease in price R'(n) = (120 - 4n)(80 + 5n)
Using the product rule, we have:
dR'/dn = (120 - 4n)(5) + (80 + 5n)(-4)
this is = 600 - 20n - 320 - 20n
= -40n + 280
equate to 0
-40n + 280 = 0
n = 7
The new price would then be
120 - 4 * 7
= 120 - 28
= 92 dollars
The maximum revenue calculation(120 - 65)(80 + 85)
= 90(120)
= $10,800
(120 - 47)(80 + 57)
= 92(115)
= $10,580
The first revenue model results in a greater maximum monthly revenue.

Answers
Answer: 0.9360
Step-by-step explanation: To find the probability that at least one of the three people has been vaccinated, we need to find the probability that none of them have been vaccinated and then subtract that from 1.
The probability that a person has not been vaccinated is 1 - 0.6 = 0.4. Therefore, the probability that all three people have not been vaccinated is:
P(no one vaccinated) = 0.4 × 0.4 × 0.4 = 0.064
So, the probability that at least one of the three people has been vaccinated is:
P(at least one vaccinated) = 1 - P(no one vaccinated) = 1 - 0.064 = 0.936
Therefore, the probability that at least one of the three people has been vaccinated is 0.936 (to 4 decimal places).

To find the domain of the function f(x) = -7x + 3 when the range is 10, we need to solve for x.
Let y = f(x) = -7x + 3
Since we know that the range of the function is 10, we can set y = 10 and solve for x.
10 = -7x + 3
7x = -7
x = -1
Therefore, the only value of x that produces a range of 10 is x = -1.
Thus, the domain of the function is { -1 }.
