According to the concept of inequality, the maximum value of A is obtained when a = 2 and c = 28.
Let's assume that each minute of advertising attracts 40,000 viewers and each minute of comedy attracts 45,000 viewers. Therefore, the total audience (in thousands) that can be reached is given by:
A = 40a + 45c
Firstly, we know that the total time allotted for advertising and comedy cannot exceed 30 minutes. Therefore, we can rewrite the inequality as:
a + c ≤ 30
Solving for c, we get:
c ≤ 30 - a
Now, we can substitute this expression for c in the equation for A:
A = 40a + 45c
A = 40a + 45(30 - a)
A = 1350 - 5a
To maximize A, we need to find the value of a that will result in the maximum value of A. Taking the derivative of A with respect to a and setting it equal to zero, we get:
dA/da = -5 = 0
a = 0
This does not make sense, as a cannot be zero. Therefore, we need to check the endpoints of the interval [2,4] to see if they give a maximum value for A.
When a = 2, we get:
A = 40(2) + 45c
A = 80 + 45c
Substituting c = 30 - a, we get:
A = 80 + 45(30 - 2)
A = 80 + 1350
A = 1430
When a = 4, we get:
A = 40(4) + 45c
A = 160 + 45c
Substituting c = 30 - a, we get:
A = 160 + 45(30 - 4)
A = 160 + 1215
A = 1375
This means that the producer should allocate 2 minutes for advertising and 28 minutes for the comedy program in order to maximize the number of viewers.

Find all values of x in the interval [0, 2π] that satisfy the equation. (Enter your answers as a comma-separated list.) 10 sin2(x) = 5
The equation 10sin^2(x) = 5 can be solved to find the values of x in the interval [0, 2π] that satisfy it. In this equation, we have to find the values of x that make the squared sine of x equal to 0.5.
To solve this equation, we first divide both sides by 10, giving us sin^2(x) = 0.5. Taking the square root of both sides, we get sin(x) = ±√(0.5).
The square root of 0.5 is approximately ±0.707. So, sin(x) can be either 0.707 or -0.707. In the interval [0, 2π], sin(x) is positive in the first and second quadrants, while it is negative in the third and fourth quadrants.
In the first and second quadrants, sin(x) = 0.707 has two solutions: x = π/4 and x = 3π/4. In the third and fourth quadrants, sin(x) = -0.707 also has two solutions: x = 5π/4 and x = 7π/4.
Therefore, the values of x in the interval [0, 2π] that satisfy the equation 10sin^2(x) = 5 are x = π/4, 3π/4, 5π/4, and 7π/4.

The amount of money that I will have at the end of 20 years would be =$4,480. That is option D
What is compound interest?Compound interest is defined as the interest that is being earned on an account which is based on the rate and the time the investment was made.
The total amount invested (p)= $2,000
The rate of investment (r) = 5%
The time of investment(t)= 12 year
The compound interest warm from that account;
= P×T×R/100.
= 2,000×12×5/100
= 120000/100
= $1200
For the next 8 years with the rate of 8% ;
= 2,000×8×8/100
= 128000/100
= $1280
The total compound interest = $1200+$1280= $2,480

If two cards are drawn from a deck, what is the probability that exactly one of the cards will be a face card?
The probability of getting exactly one face card is 0.72.
According to the questions two cards are drawn from a deck.
Since, we know that
Total number of cards in a deck = 52
Total number of face cards = 3 × 4 = 12
So, the number of ways of selecting 2 cards from a deck = \(^{52} C_{2}\)
And, the total number of ways of getting exactly one face cards
= \(^{12} C_{1} \times ^{40} C_{1}\) + \(^{40} C_{1} \times ^{12} C_{1}\)
= 2\(^{40} C_{1} \times ^{12} C_{1}\)
Therefore, the probability of getting exactly one face card
= \(\frac{2(^{40} C_{1} \times ^{12} C_{1})}{^{52C_{2} } }\)
\(= \frac{2(\frac{40 \times 39!}{1!\times 39!} \frac{12\times 11!}{11!}) }{\frac{52\times 51\times 50!}{2!\times50!} }\)
\(= \frac{2(40\times 12)}{26\times 51}\)
\(=\frac{2\times 480}{1326}\)

In the rectangle shown below, the length is longer than its width w. List all the possible
whole number dimensions for the rectangle, and name the dimensions that give the smallest
perimeter.
Area is 40 m2
Answer: w can be 1,2,4,5
Step-by-step explanation:
Let's recap the formula of Area:
Area = width x length = w x l
Area = 40 = w x l
The definition of a whole number: is a number without fractions; an integer such as 0, 1, 2, 3, 4, 5, 6,...
Let's start with 0. 0 times anything is equal to 0, so we cannot make 40 out of zero. Cross this out.
Next, let's try with 1:
a. 1x40 = 40
Then, applying the same concept to the rest we have these multiplications:
b. 2x20 = 40
c. 4x10 = 40
d. 5x8 = 40
e. 8x5 = 40
f. 10x4 = 40
g. 20x2 = 40
h. 40x1 = 40
Let's recap the formula of Perimeter:
P = 2 x (w + l)
So, we have the calculated perimeters (according to the above finding):
a. P= 2x(1+40)=82
b. P= 2x(2+20)=44
c. P= 2x(4+10)=28
d. P= 2x(5+8)=26
The below answers do not fit the [width < length]
e. P= 2x(8+5)=26 [not an answer]
f. P= 2x(10+4)=28 [not an answer]
g. P= 2x(20+2)=44 [not an answer]

the cost of renting a car for one day and driving m miles if the rate is $49 per day plus 5 cents per mile
Answer:
\(Total\ Rent = 49 + 5m\)
Step-by-step explanation:
Given
Rent per day = $49
Addition = 5 cents per mile
Required
Determine the rent for a day and m miles
First, we need to generate a formula from the given parameters;
Let d represent number of days and m represent additional miles;
\(Total\ Rent = 49 * d + 5 * m\)
\(Total\ Rent = 49 d + 5 m\)
Solving for the rent for a day and m miles
We have that: d = 1 and m = m
Substitute these in the formula above
\(Total\ Rent = 49 * 1 + 5 * m\)
\(Total\ Rent = 49 + 5m\)
Hence, the total rent is
\(Total\ Rent = 49 + 5m\)

how many even integers are there between 200 and 700 whose digits are all different and come from the set {1,2,5,7,8,9]
There are 48 even integers between 200 and 700 whose digits are all different and come from the set {1, 2, 5, 7, 8, 9}.
To find the number of even integers between 200 and 700 with all different digits from the set {1, 2, 5, 7, 8, 9}, we can consider the possible choices for each digit.
For the hundreds digit, we have the options 2, 5, and 7 (3 choices). For the tens digit, we have the options 1, 5, 7, 8, and 9, excluding the hundreds digit chosen (4 choices). For the units digit, we have the options 2, 4, 6, and 8 (4 choices).
To calculate the total number of even integers, we multiply the number of choices for each digit. Therefore, the total number of even integers is 3 choices for the hundreds digit × 4 choices for the tens digit × 4 choices for the units digit = 3 × 4 × 4 = 48.
Hence, there are 48 even integers between 200 and 700 whose digits are all different and come from the set {1, 2, 5, 7, 8, 9}.

The money collected from a Saturday car wash are directly proportional to the number of cars washed. The total money collected after 7 cars is $140. Write an direct variation equation relating the money collected (m) and the number of cars washed
Answer:
\(m=20c\)
Step-by-step explanation:
Let m represent the total money collected and c represent the amount of cars washed.
We know that the money collected is directly proportional to the number of cars washed. So, we can write the following equation:
\(m=kc\)
Where k is a constant.
We know that the money collected after 7 car washes is $140. So, let's find our k by substituting 140 for m and 7 for c. This yields:
\(140=7k\)
Find k. Divide both sides by 7:
\(k=20\)
So, the value of k is 20.
We can now substitute k back into our direct variation equation:
\(m=20c\)
This means that every car costs $20 to wash.
