The equation Pt=P₀[tex]e^-0[/tex]. 4t is used to predict the ticket sales of a movie after its release. For the latest blockbuster movie, the predicted ticket sales for the sixth week of the movie’s release is $7. 9 million to the nearest $0. 1 million.

The formula used to predict the number of ticket sales t weeks after a movie’s release is Pt=P₀[tex]e^-0[/tex]. 4t, where P₀ is the first week’s ticket sales. In the case of the latest blockbuster movie, the first week’s ticket sales was $16. 3 million. To calculate the predicted ticket sales for the sixth week, the time t must be set to 6. The equation then becomes , which simplifies to Pt=7. 9 million. The predicted ticket sales for the sixth week of the movie’s release is therefore $7. 9 million to the nearest $0. 1 million. The equation  is a useful tool for predicting the ticket sales of a movie over time. It reflects the fact that, generally, ticket sales for a movie will steadily decline over time, with the rate of decline being determined by the value of the exponent, -0. 4 in this case. By plugging in different values for t, one can easily calculate the predicted ticket sales for a movie at any given time.

The domain of a function refers to the set of all possible input values. We can easily find the domain of the given function h(t) using the following rules:

Since the denominator cannot be zero, we must exclude the value t = -3 from the domain. This means that the domain is {t | t ≠ -3}.

Furthermore, the expression inside the square root cannot be negative since the square root of a negative number is undefined. Thus, we have t^2 - 16 ≥ 0, which implies t ≤ -4 or t ≥ 4.

Therefore, the domain of the function h(t) is given by {t | t ≠ -3, t ≤ -4 or t ≥ 4}. This can also be written in set-builder notation as {t : t ≤ -4 or t ≥ 4, t ≠ -3}.

Hence, the correct option is {\color{Red}\boxed{(-\infty,-4] \cup[4, \infty) \text { or }{x \mid x \leq-4 \text { or } x \geq 4}}}

Answer:

142.5 ft^2

Step-by-step explanation:

You need to calculate each figure separately

area of the first rectangle = 5 x 4 = 20

area of the second rectangle = (5+6)x(4) = 44

area of 1/4 circle =  1/4π(10^2) = (1/4) x 3.14 x 100 = 78.5

area of figure: 78.5 + 20 + 44 = 142.5

Answer:

To find the area of this figure, we need to first determine its shape. The lengths given do not form a clear shape, so we need more information to determine the shape.

Assuming that the shape is a trapezoid with the bases of 6ft and 10ft, and a height of 5ft, we can use the formula for the area of a trapezoid:

Area = (b1 + b2) / 2 * h

where b1 and b2 are the lengths of the two parallel bases, and h is the height of the trapezoid.

Plugging in the values, we get:

Area = (6ft + 10ft) / 2 * 5ft

Area = 8ft * 5ft

Area = 40 sq ft

Area ≈ 3.73 sq m (rounded to two decimal places)

Therefore, the area of this figure is approximately 3.73 square meters.

(If it wasn't in decimals, it would be 40 square feet.)

Step-by-step explanation:

If the square of the binomial x+1 one hundred and 20 greater than the square of the binomial x-3, the value of x that satisfies the equation is x = 13.75.

Let's start by using the formula for the square of a binomial:

(a + b)^2 = a^2 + 2ab + b^2

In this case, we have:

(x + 1)^2 = x^2 + 2x + 1 (square of the binomial x+1)

(x - 3)^2 = x^2 - 6x + 9 (square of the binomial x-3)

We're told that the square of the binomial x+1 is 120 greater than the square of the binomial x-3. In other words:

(x + 1)^2 = (x - 3)^2 + 120

Substituting the expressions we found above, we get:

x^2 + 2x + 1 = x^2 - 6x + 9 + 120

Simplifying, we get:

8x = 110

Therefore, the solution is:

x = 13.75

The number of signatures they got on the first day is 2.

The problem can be solved mathematically by using the formula for geometric sequences, which is:

an = a1 × r^(n-1)

where:

an = the nth term in the sequence

a1 = the first term in the sequence

r = the common ratio between consecutive terms

n = the number of terms in the sequence

In this case, we know that the number of signatures they get each day is twice as many as the day before, which means that the common ratio is 2. We also know that the number of signatures they got on the sixth day is 2^6 = 64.

Using the formula for geometric sequences, we can solve for a1 by substituting the known values

The increase in price for both appliances is the same, which is ₹400

Let's first find the increase in price for the toaster:

Increase in price = New price - Old price

Increase in price = ₹800 - ₹400

Increase in price = ₹400

Now, let's find the increase in price for the microwave:

Increase in price = New price - Old price

Increase in price = ₹10400 - ₹10000

Increase in price = ₹400

As we can see, the increase in price for both appliances is the same, which is ₹400.

The increase in price for both appliances is ₹400. This is found by subtracting the old price from the new price for each appliance. For the toaster, the increase is ₹800 - ₹400 = ₹400. For the microwave, the increase is ₹10400 - ₹10000 = ₹400. Since both appliances had the same increase in price, we can conclude that the percentage increase is different for each appliance. In this case, the percentage increase for the toaster is 100% [(₹800 - ₹400)/₹400 x 100%], while the percentage increase for the microwave is only 4% [(₹10400 - ₹10000)/₹10000 x 100%].

Step-by-step explanation:

To simplify the expression 16+(-3)-3/7j-6/7j+4, we first need to combine like terms. The real numbers (16, -3, and 4) can be added together, and the imaginary numbers (-3/7j and -6/7j) can also be added together. So we have:

16 + (-3) + 4 + (-3/7j) + (-6/7j)

Simplifying the real numbers:

= 16 - 3 + 4

= 17

Simplifying the imaginary numbers:

= (-3/7j) + (-6/7j)

= (-9/7j)

Putting it all together, we get:

16 + (-3) - 3/7j - 6/7j + 4 = 17 - 9/7j

So the simplified expression is 17 - 9/7j.

As per the given rectangle, the length of EG is 5x - 7

We are given that DEFG is a rectangle, which means that its opposite sides are parallel and equal in length. Let's label the sides of the rectangle as follows:

DE = FG = a (since opposite sides of a rectangle are equal in length)

EF = DG = b (since opposite sides of a rectangle are parallel)

Now, we can use the given information to set up an equation for the length of EG:

EG = EF + FG = b + a

But we don't know the values of a and b. However, we are given that FD = 3x - 7 and EG = x + 5. We can use this information to solve for a and b.

We know that FD = DE - EF, so we can substitute the values we have:

3x - 7 = a - b

We also know that EG = FG - DG, so we can substitute the values we have:

x + 5 = a - b

Now we have two equations with two variables (a and b). We can solve for a and b by adding the two equations together:

3x - 7 + x + 5 = 2a

4x - 2 = 2a

a = 2x - 1

Now we can substitute this value for a in one of the earlier equations to solve for b:

3x - 7 = (2x - 1) - b

b = 3x - 6

Finally, we can substitute the values we found for a and b into the equation we set up earlier to find the length of EG:

EG = EF + FG = b + a = (3x - 6) + (2x - 1) = 5x - 7

Therefore, the length of EG is 5x - 7.

The given information tells us that a particular country has 22.9% of the employees of an international company, and this amounts to 19700 employees.

The given statement implies that the international company has a total number of employees working in various countries. Out of these, 22.9% of the employees are working in a particular country, which amounts to 19700 employees in that country.

To find out the total number of employees working in all countries, we can use the following formula:

Total number of employees = Number of employees in the given country / Percentage of employees in the given country

Substituting the values given in the problem, we get:

Total number of employees = 19700 / 0.229

Total number of employees = 85939.3

Therefore, the international company has approximately 85939 employees working in various countries.

It's important to note that this calculation assumes that the proportion of employees working in the given country is representative of the proportion of employees working in other countries. However, if the proportion of employees working in other countries is significantly different, then the actual number of employees in the company could be different from the calculated value.

In conclusion, the given information tells us that a particular country has 22.9% of the employees of an international company, and this amounts to 19700 employees. We can use this information to approximate the total number of employees working in all countries.

The risk of hepatoma among alcoholics without cirrhosis of the liver is 24%.We need to find the probability that exactly one of these 7 people have a hepatoma. Let the probability of having hepatoma be P(A) = 24% = 0.24 (given). Therefore, the probability of not having a hepatoma is P(A') = 1 - P(A) = 1 - 0.24 = 0.76. We have n = 7 people.

The probability of exactly 1 person having a hepatoma is P(1 person having hepatoma) = C(7,1) × P(A) × [tex]P(A')^{6}[/tex].

C(n, x) is the combination of n things taken x at a time. C(7,1) = 7!/1!6! = 7P(1 person having hepatoma) = 7 × 0.24 × (0.76)⁶= 0.35

The smallest number of peanuts that could be in the bag is 4320.

Let's use the Chinese Remainder Theorem to solve this problem.

Let:

x be the number of peanuts in the bag.

Then we know that x ≡ 2 (mod 8), x ≡ 2 (mod 9), and x ≡ 2 (mod 10).

Using the Chinese Remainder Theorem, we can find a solution for x as follows:

Let

M = 8 * 9 * 10 = 720, and let M1, M2, and M3 be the remainders when M is divided by 8, 9, and 10 respectively.

That is, M1 = 720 mod 8 = 0, M2 = 720 mod 9 = 0, and M3 = 720 mod 10 = 0.

Let b1 = 1, b2 = 1, and b3 = 1.

Then we need to find integers a1, a2, and a3 such that a1 * M1 * b1 + a2 * M2 * b2 + a3 * M3 * b3 = 1.

One solution is a1 = 5, a2 = -4, and a3 = 1,

so we have 5 * 720 * 1 + (-4) * 720 * 1 + 1 * 720 * 1 = 7201

= M1 * b1 * 2 + M2 * b2 * 2 + M3 * b3 * 2.

This means that x = M1 * b1 * 2 + M2 * b2 * 2 + M3 * b3 * 2 is a solution to the system of congruences.

Since M1 = 0, we have x ≡ 0 (mod 8).

Since M2 = 0, we have x ≡ 0 (mod 9).

Since M3 = 0, we have x ≡ 0 (mod 10).

Therefore, the smallest positive integer solution for x is x = 720 * 1 * 2 + 720 * 1 * 2 + 720 * 1 * 2 = 4320.

The area of a triangle is given by the formula A = 1/2 * base * height, where "base" is the length of the triangle's base and "height" is the length of the perpendicular line segment from the base to the opposite vertex.

If the base of a triangle is doubled, the height remains constant, and the area of the triangle will also double. This is because the area of a triangle is directly proportional to its base length.

In the case of the given triangle, if the base is doubled from 3 centimeters to 6 centimeters, the area of the triangle will become:

A = 1/2 * 6 cm * 6 cm = 18 cm²

Therefore, the area of the triangle will increase from 9 cm² to 18 cm² if the base is doubled while the height remains constant at 6 cm.
