Step-by-step explanation:

You can see that the second triangle is three times the size as the first so you divde the same side on the second triangle by 3

The function that convolved with -2cos(t) would produce 6sin(t) is g(t) = -3 * e^(-jt)/(2π).

To determine the function that, when convolved with -2cos(t), would produce 6sin(t), we can use the convolution theorem. According to the convolution theorem, the Fourier transform of the convolution of two functions is equal to the product of their individual Fourier transforms.

Let's denote the function we are looking for as g(t). Taking the Fourier transform of g(t) yields G(ω), and taking the Fourier transform of -2cos(t) yields -2πδ(ω - 1), where δ(ω) is the Dirac delta function.

Using the convolution theorem, we have:

G(ω) * -2πδ(ω - 1) = 6πδ(ω + 1)

To solve for G(ω), we divide both sides of the equation by -2πδ(ω - 1):

G(ω) = -3δ(ω + 1)

Now, we take the inverse Fourier transform of G(ω) to obtain g(t):

g(t) = Inverse Fourier Transform[-3δ(ω + 1)]

The inverse Fourier transform of δ(ω + a) is given by e^(-jat)/(2π), so applying this to our equation:

g(t) = -3 * e^(-jt)/(2π)

Therefore, the function that convolved with -2cos(t) would produce 6sin(t) is g(t) = -3 * e^(-jt)/(2π).

Step-by-step explanation:

The least squares solution of the equation is x = (C, D) = (7, 0).

To find the least squares solution for the line equation b = C + Dt and draw the closest line, we need to set up a system of equations using the given data points.

Using the line equation b = C + Dt, substitute the values to form the following equations:

Equation 1: 7 = C - D

Equation 2: 7 = C + D

Equation 3: 21 = C + 2D

To find the least squares solution x = (C, D),

we want to minimize the sum of squared differences between the actual data points and the line.

This can be done by solving the system of equations using the method of least squares.

Let's solve the system of equations:

Add (1) and (2)

7 + 7 = C - D + C + D

14 = 2C

C = 7

Solving for D, we find:

7 = 7 - D

D = 0

Therefore,

The least squares solution of the equation is x = (C, D) = (7, 0).

Answer:

It will take Jack 40 minutes to cover the same distance which Micheal covers in 60 minutes. Both will meet at 3 miles distance at 3 pm.

Step-by-step explanation:

Micheal  runs 3 miles in one hour or 60 minutes.

In one minute he runs 3/60= 1/20  or 0.05miles.

Jack runs 4.5 miles in one hour or 60 minutes.

In one minute he runs 4.5/60= 45/600= 9/120= 3/40  or 0.075 miles.

So Jack is 0.075/0.05 = 1.5 times faster than Micheal.

or Micheal is 1.5 times slower than Jack.

Jack starts from 2:20 pm and at 3 pm he will run 0.075(40 minutes)= 3miles

Micheal start at 2:00 pm and at 3 pm he will run 0.05(60 minutes)= 3 miles

So at 3 pm both will have covered equal distance= 3miles.

It will take Jack 40 minutes to cover the same distance which Micheal covers in 60 minutes. Both will meet at 3 miles distance at 3 pm.

The equatiion where C is the constant of integration.To evaluate the indefinite integral ∫(3e^x + 4x^5 - x^3/4 + 1)dx, we can integrate each term separately.

∫3e^x dx = 3∫e^x dx = 3e^x + C₁

∫4x^5 dx = 4∫x^5 dx = 4 * (1/6)x^6 + C₂ = (2/3)x^6 + C₂

∫-x^3/4 dx = (-1/4)∫x^3 dx = (-1/4) * (1/4)x^4 + C₃ = (-1/16)x^4 + C₃

∫1 dx = x + C₄

Now, we can combine these results to obtain the final answer:

∫(3e^x + 4x^5 - x^3/4 + 1)dx = 3e^x + (2/3)x^6 - (1/16)x^4 + x + C

Therefore, the indefinite integral of (3e^x + 4x^5 - x^3/4 + 1)dx is:

∫(3e^x + 4x^5 - x^3/4 + 1)dx = 3e^x + (2/3)x^6 - (1/16)x^4 + x + C

The total cost to build a 3-on-3 court, using area and perimeter formula is obtained as $528.

What is perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.

As the court area is 165 square meters, we need to calculate the perimeter to determine the amount of asphalt needed for the court.

Assuming the court is rectangular, we can use the formula -

Perimeter = 2 × (length + width)

To find the length and width, we need to know the aspect ratio of the court.

According to FIBA regulations, a 3-on-3 court should have an aspect ratio of 1:1.5, meaning the length should be 1.5 times the width.

Let's assume the width of the court is x meters.

Then, the length of the court would be 1.5x meters.

The area of the court is given by -

Area = length × width

165 = 1.5x × x

165 = 1.5x²

x² = 165 / 1.5

x² = 110

x = √110

x ≈ 10.49

Therefore, the width of the court is approximately 10.49 meters, and the length is 1.5 times that, or approximately 15.73 meters.

The perimeter of the court is -

Perimeter = 2 × (length + width)

Perimeter = 2 × (15.73 + 10.49)

Perimeter = 52.42 meters

Now, we need to convert the perimeter to the amount of asphalt needed. According to industry standards, one ton of asphalt covers 9.29 square meters at a thickness of 5 cm.

The thickness of the asphalt will depend on the existing ground conditions, but assuming we need a thickness of 5 cm, the amount of asphalt needed is -

Asphalt needed = (Perimeter × Thickness) / 9.29

Asphalt needed = (52.42 × 0.05) / 9.29

Asphalt needed = 0.28 tons

Therefore, the amount of asphalt is 0.28 tons.

If the cost of asphalt is $100 per ton, then the cost of the required amount of asphalt would be -

Cost of asphalt = Asphalt needed × Cost per ton

Cost of asphalt = 0.28 × $100

Cost of asphalt = $28

We also need to factor in the cost of hoops and paint.

As per the problem statement, the quantity of hoops and paint required is the same as that for a 5-on-5 court.

Assuming the cost of hoops and paint for a 5-on-5 court is $500, the total cost of building the 3-on-3 court would be -

Total cost = Cost of asphalt + Cost of hoops and paint

Total cost = $28 + $500

Total cost = $528

Therefore, the total cost to build a 3-on-3 court with an area of 165 square meters, assuming the cost of asphalt is $100 per ton and the cost of hoops and paint is $500, is $528.

When x and y are in direct proportion, the value of y when the value of x is 11 is 77.

What is meant by direct proportion?

The relationship between two values where their ratio equals a constant number is known as a direct proportion or direct variation. Sometimes, we notice that changes in one quantity's value are similar to changes in another quantity's value, meaning that when one quantity's value rises, the other quantity's value rises in the same proportion and vice versa. Two quantities are said to exist in direct proportion when such circumstances occur. According to the direct proportion formula, if y is directly proportional to x, we can state that y = kx, where k is a constant.

When x and y are in direct proportion, we can write,

x/y = c

where c is a constant.

Now it is given that y = 42 , when x = 6

then c = x/y = 6/42 = 1/7

We are asked to find the value of y when x = 11.

The c remains constant.

so 11/y = 1/7

y = 11*7 = 77

Therefore when x and y are in direct proportion, the value of y when the value of x is 11 is 77.

For maximum strength training, it is recommended to perform 1 to 5 repetitions per set, with heavier weights and longer rest periods between sets. This type of training focuses on increasing muscle strength and power.

Maximum strength training is a type of resistance training that is designed to increase muscle strength and power. The number of repetitions per set is an important factor in developing maximum strength, and the recommended range is between 1 and 5 repetitions. For this type of training, heavier weights and longer rest periods between sets are used. This allows the muscles to recover and build strength. During each set, the goal is to lift the weight as fast and explosively as possible, to help increase muscle power. It is important to also keep proper form and technique when performing exercises, as any incorrect movements can result in injury. Maximum strength training should be done with a gradual increase in weight, so that the body can properly adjust to the new load. It is also important to vary the exercises and the intensity level to help the body adapt to the training and to avoid plateaus in progress. To ensure optimal results, it is recommended to consult with a professional trainer or physical therapist.

Step-by-step explanation:

Two-tailed because there is no predicted direction of the difference. The correct answer is D.

In hypothesis testing, a one-tailed test is used when the researcher has a specific prediction about the direction of the effect. They expect the results to be either greater than or less than a certain value. However, in this scenario, the researcher simply wants to investigate whether the new type of exercise improves people's health without any specific directional prediction.

A two-tailed test is appropriate when the researcher wants to determine if there is a significant difference between the groups being compared, but without specifying the direction of the difference. In this case, the researcher wants to examine if the new exercise has any effect on health, whether it improves or worsens it. Therefore, a two-tailed test is suitable as it allows for the possibility of observing a significant difference in either direction.

Therefore, considering these factors, the researcher should conduct a two-tailed test to assess the potential impact of the new exercise on people's health. The correct answer is D.
