c) Bhurashi can do part of a work in 1 day. She worked for 4 days and 20 left. If the remaining parts of the work was done by Rita, how much work did she do ?​

The formula is: f(x) = 2 * sin(x * 5 / 2π) + 5

A = 5 - 3 = 2, the amplitude of the function.

Since (0,3) is the minimum, the midline is at y = 3 + 2 = 5, the average value of the maximum and minimum.

Let "c" be the shift, so the equation of the midline is y = 5 + c.

At x = 5, the function intersects its midline, so 5 = 5 + c.

Therefore, c = 0.

The period of the function is 2π / b, where b is the number of radians for one complete cycle.

Since the function intersects its midline at (5,5), b = 5.

Therefore, the period of the function is 2π / 5.

The formula of the sinusoidal function is:

f(x) = A * sin(b * (x - c)) + d,

where d = 5, the equation of the midline.

Therefore, the formula is:

f(x) = 2 * sin(x * 5 / 2π) + 5

what are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

At the beginning of 2072 B.S., the population of the town was X.

Assuming the population growth rate is 10%, the population at the end of 2074 B.S. will be (X + 10% of X) + (X + 10% of X + 10% of X) = 1.1X + 1.1(1.1X) = 2.21X.

Therefore, the population of the town at the end of 2074 B.S. will be 2.21X. This is based on a linear population growth rate of 10% over two years. It is possible that the growth rate may not be constant, so the actual population may be slightly different.

In order to get a better estimate of the population at the end of 2074 B.S., it is important to consider other factors such as birth and death rates, migration, and economic and social factors.

For example, if the town is experiencing an influx of migrants, then the population growth rate may be higher than the estimated 10%. On the other hand, if the town faces an economic recession or job losses, then the population growth rate may be lower than the estimated 10%.

Overall, the population of the town at the end of 2074 B.S. is estimated to be 2.21X, based on a linear population growth rate of 10% over two years. However, this estimate may be slightly different depending on the other factors mentioned above.

Answer:

[tex]x=\dfrac{20}{3}\; \sf cm[/tex]

Step-by-step explanation:

If a line is parallel to a side of a triangle and intersects the other two sides, then this line divides those two sides proportionally.

Applying the side-splitter theorem:

[tex]\implies \dfrac{3}{5}=\dfrac{4}{x}[/tex]

Cross multiply:

[tex]\implies 3 \cdot x=4 \cdot 5[/tex]

[tex]\implies 3x=20[/tex]

Divide both sides by 3:

[tex]\implies \dfrac{3x}{3}=\dfrac{20}{3}[/tex]

[tex]\implies x=\dfrac{20}{3}[/tex]

Therefore, the value of x is ²⁰/₃ cm

Using the permitted $110 for travel, the businessperson can cover 291 miles.

We need to deduct the daily rate of $37.33 from the permitted money, then divide the sum by the per-mile rate of 25 cents to get how many miles a businessperson can travel with $110.

$110 - $37.33 = $72.67

$72.67 ÷ $0.25 = 291 miles

It's crucial to remember that, regardless of how many kilometres the businessperson drives, the daily charge includes a fixed sum for the rental automobile. Each mile driven results in an additional fee known as the per-mile tariff. We may calculate the maximum number of miles the business person can travel without incurring additional costs by subtracting the daily rate from the permitted amount and dividing by the per-mile rate.

The required distance between the two given cities using the distance formula is 93 miles.

Distance is the sum of an object's movements, regardless of direction.

The distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

Learn how to apply the Pythagorean theorem to find the distance between two points using the distance formula.

The Pythagorean theorem can be rewritten as d=(((x 2-x 1)2+(y 2-y 1)2) to calculate the separation between any two locations.

So, we have the points:

(53, 17) and (123, 78)

Distance formula:

d = √(x2-x1)² + (y2-y1)²

Now, calculate as follows:

d = √(x2-x1)² + (y2-y1)²

d = √(123-53)² + (78-17)²

d = √(70)² + (61)²

d = √(4,900) + (3,721)

The probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice is approximately 0.5949 (rounded off to third decimal place).

To find the probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice, we need to find the cumulative distribution function (CDF) of a normal distribution with a mean of 500 and standard deviation 4.

Using the Z-score formula, we can calculate the Z-score for 499 ml of juice: (499-500)/4 = -0.25

Next, we use a standard normal table to find the probability of a Z-score less than -0.25, which is 0.4051.

Finally, we use the CDF formula for a normal distribution to find the probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice:

P(X < 499) = 1 - P(X >= 499) = 1 - 0.4051 = 0.5949

According to the problem the volume of the solid generated by revolving the region is .

The amount of space a thing occupies is its volume, which is expressed in cubic units. It is a three-dimensional measure of an object's size, as opposed to its length and width, which are considered two-dimensional measures. Volume is commonly used to measure the capacity of containers, such as barrels, tanks, and boxes.

This is a solid of revolution generated by revolving the region bounded by the curves y=[tex]e^{(x-9)}[/tex] and y=0 and the lines x=9 and x=10 about the x-axis. To find the volume of this solid, we can use the method of washers.

The formula for the volume of a solid of revolution generated by revolving a region bounded by two curves about the x-axis is given by:

V = π∫[tex]b a [((f(x))^{2} - (g(x))^{2}] dx[/tex]

In this problem, f(x) = [tex]e^{(x-9)}[/tex] and g(x) = 0. Thus,

V = π∫10 9 [tex]e^{(2x-18)} dx[/tex]

Integrating, we get

V = π [tex][\frac{e^{(2x-18)}}{2}] 10^{9}[/tex]

V = π(157.087 - 1.1102)/2

V = 78.488π [tex]cm^{3}[/tex] equal to the integral of the area of the region over the interval [9, 10] with respect to x.

The area of the region is equal to the integral of y from 9 to 10. Thus, the volume of the solid generated by revolving the region is equal to the double integral:

V = ∫[tex]9^{10}[/tex] ∫[tex]0^{e^{(x-9)} } dy dx[/tex]

Evaluating the integral yields:

V =∫ [tex]9^{10} e^{(x-9)} dx[/tex]

[tex]= \frac{e^{(x-9)} }{9^{10} }\\ =e^{1} -1\\ =2.718-1 =1.718[/tex]

Probability is a measure of the likelihood that a specific event will occur in a random experiment.

What is the Probability?

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

In other words, the probability is a number that represents the chance or chance of an event occurring out of all possible outcomes.

It is expressed as a fraction, decimal, or percentage.

For example, if there is a 50% chance of rain, this means that the probability of rain is 0.5 or 1/2.

Probability is important in decision-making, risk assessment, and mathematical modeling. It helps to quantify uncertainty and provides a way to assess the likelihood of different outcomes.

Hence, Probability is a measure of the likelihood that a specific event will occur in a random experiment.

Answer:

This is the equation of the normal line at the point (2, 1) on the ellipse (x^2)/4 + y^2 = 2.

Step-by-step explanation:

The equation of the ellipse is (x^2)/4 + y^2 = 2. To find the equation of the normal line at the point (2, 1), we first need to find the slope of the tangent line at that point. To do this, we can use the formula for the slope of a tangent line:

slope = -(d/dx)(f(x)) / (d/dy)(f(y))

Where f(x) and f(y) are the equations of the ellipse.

So,

slope = -(x/2)/y = -x/2y

Now we can substitute the point (2, 1) into the equation for the slope:

slope = -(2/2)/1 = -1

We know that the slope of the normal line is the negative reciprocal of the slope of the tangent line, so the slope of the normal line is 1.

To find the equation of the normal line, we can use the point-slope form of a line:

y - y1 = m(x - x1)

Where (x1, y1) is the point on the line and m is the slope.

So,

y - 1 = 1(x - 2)

Simplifying, we get:

y = x - 1

This is the equation of the normal line at the point (2, 1) on the ellipse (x^2)/4 + y^2 = 2.

b) The total amount of money collected from admissions to the park on the given day is the sum of the money collected before 5:00 P.M. and the money collected after 5:00 P.M.

Now finding the definite integral of the function

11*9890/(t^2 - 38t + 370) for t from 17 to 23.

c) H(t) represents the number of people in the park at time t. H'(t) represents the rate at which the number of people in the park is changing at time t.

H(17) = 3725 means that at 5:00 P.M. there are 3725 people in the park.

H'(17) can be found by finding the derivative of the function H(t) at t = 17.

d) To find the time t at which the model predicts that the number of people in the park is a maximum, we need to find the maximum value of H(t) for 9 ≤ t ≤ 23.

This can be done by finding the derivative of H(t), setting it equal to 0, and solving for t.
