Answer: \(\sqrt{65}\)

Step-by-step explanation:

Concept:

Here, we need to know the concept of the distance formula.

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

Find the length of UV, where:

\(Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

\(Distance = \sqrt{(1-2)^2+(-9+1)^2}\)

\(Distance = \sqrt{(-1)^2+(-8)^2}\)

\(Distance = \sqrt{1+64}\)

\(Distance = \sqrt{65}\)

Hope this helps!! :)

tan Q=15/8.................

61 is the sum of two consecutive integers (-6,-5 ) and (5,6).

According to Pierr De Fermat any whole number writteen as the sum of four or less square numbers.

So 61 is the whole number so we can write in the sum of squares,

Now we know even+odd=odd so that let a and a+1 integer , according to Pierr De Fermat we can write,

a²+(a+1)²=61;

⇒a²+a²+2a+1=61

⇒2a²+2a-60=0

⇒a²+a-30=0 (∵divided by 2)

⇒a²+6a-5a-30=0

⇒a(a+6)-5(a+6)=0

⇒(a+6)(a-5)=0

⇒a+6=0 or a-5=0 ⇒a=-6 or a=5

If a=-6 then a+1=-6+1=-5.

if a=5 then a+1=5+1= 6.

so 61= (-6)²+(-5)² and 61= 6²+5².

The long jump pit was recently rebuilt to make it level with the runway.  the amount of wood, in meters, is 12.29 meters.

Generally, To determine the amount of wood needed in meters, you will need to convert the length of each piece of wood from feet to meters. You can use the conversion factor that 1 foot is equal to approximately 0.3048 meters.

To convert the length of the wood from feet to meters, you can use the formula:

length in meters = length in feet * 0.3048

Using this formula, you can calculate that 2.75 meters is equal to approximately 9 feet, and 9.54 meters is equal to approximately 31.25 feet.

Therefore, the total amount of wood needed in meters is 2.75 meters + 9.54 meters = 12.29 meters.

a. The formula B = 703w/h^2 can be solved for w by rearranging the equation as w = B * h^2 / 703.
b. For a person who is 64 inches tall and has a body mass index of 21.45, the weight can be calculated by substituting the values into the formula w = B * h^2 / 703, where B is 21.45 and h is 64 inches.

a. To solve the formula B = 703w/h^2 for w, we can rearrange the equation to isolate w on one side of the equation. Multiply both sides of the equation by h^2, then divide both sides by 703. The resulting equation is w = B * h^2 / 703.
b. To find the weight of a person who is 64 inches tall and has a body mass index of 21.45, we can substitute the values into the formula w = B * h^2 / 703. In this case, B is 21.45 and h is 64 inches. Plugging these values into the equation, we get w = 21.45 * 64^2 / 703. Evaluating this expression will give us the weight in pounds.

If in 25 minutes, 400 customers entered the attraction then in 90 minutes (1.5 hours), approximately 1440 customers would enter the attraction.

In 25 minutes, 400 customers entered the attraction. We need to determine how many customers would enter the attraction in 1.5 hours (90 minutes).

To find the number of customers entering the attraction in 1.5 hours, we can use the concept of proportions.

We know that in 25 minutes, 400 customers entered the attraction.

Let's set up a proportion to find the number of customers in 90 minutes:

25 minutes / 400 customers = 90 minutes / x customers

To solve for x, the number of customers in 90 minutes, we can cross-multiply and solve for x:

25 minutes * x customers = 400 customers * 90 minutes

Simplifying, we get:

25x = 36000

Dividing both sides of the equation by 25, we find:

x = 1440

Therefore, in 90 minutes (1.5 hours), approximately 1440 customers would enter the attraction.

Step-by-step explanation:

Given the surface area of a cone expressed as S = \(\pi r^{2} +\pi rl\) where r is the radius of the cone and 'l' is its slant height. To find the slant height from the formula, we will make l the subject of the formula as shown;

\(S = \pi r^{2} + \pi rl\\S = \pi r (r + l)\\\frac{S}{\pi r} = r+l\\l = \frac{S}{\pi r} - r\\\)

The differences between the annual interest and semi-annual interest will be Rs 435.78.

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

We know that the compound interest is given as

A = P(1 + r)ⁿ

Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.

The same of annual interest and semi-annual compound interest on a same of money for 2 years at the interest rate of 20% per annum is Rs. 18082.

The annual interest will be

⇒ 18082(1.2)² – 18082

⇒ Rs 7956.08

The semi-annual interest will be

⇒ 18082(1.1)⁴ – 18082

⇒ Rs 8391.86

Then the differences between the annual interest and semi-annual interest will be

The estimated time for the 100th repetition of this job is approximately 111.11 minutes, assuming a learning curve of 90 percent.

To estimate the time for the 100th repetition of the job, we can use the concept of a learning curve. The learning curve assumes that as the number of repetitions increases, the time required decreases at a constant percentage rate. In this case, the learning curve is 90 percent.

To estimate the time for the 100th repetition, we can use the formula:

Estimated time for the 100th repetition = Time for the 50th repetition / (Learning curve)\(^log2\)(100/50)

Plugging in the given values:

Estimated time for the 100th repetition = 100 minutes / (0.90)\(^log2(100/50)\)

Simplifying the expression:

Estimated time for the 100th repetition ≈ 100 minutes / \((0.90)^1\)

Estimated time for the 100th repetition ≈ 100 minutes / 0.90

Estimated time for the 100th repetition ≈ 111.11 minutes

Therefore, the estimated time for the 100th repetition of this job is approximately 111.11 minutes.

The correct statement is c. The Adjusted R-squared is a measure used in multiple regression analysis that is between 0 and 1. It is different from the R-squared value in simple linear regression.

The Adjusted R-squared can decrease if the addition of another X regressor does not sufficiently lower the sum of squared residuals (SSR) relative to the impact of increasing the number of predictors (k). It measures the proportion of the variance explained by the predictors, adjusted for the number of predictors and the sample size, rather than the ratio of the sum of squared residuals to the total sum of squares. It provides a measure of how well the regression model fits the data, and it ranges between 0 and 1. A value closer to 1 indicates that a higher proportion of the variance in the dependent variable is explained by the predictors.

Adding another X regressor to the multiple regression model can impact the Adjusted R-squared. If the additional regressor does not significantly contribute to reducing the sum of squared residuals (SSR) relative to the increase in the number of predictors (k), the Adjusted R-squared can decrease. This means that the added regressor does not improve the model's ability to explain the variance in the dependent variable adequately.

However, the Adjusted R-squared does not directly measure the ratio of the sum of squared residuals to the total sum of squares. Instead, it represents the proportion of the variance explained by the predictors, adjusted for the number of predictors and the sample size. It penalizes models with a large number of predictors that may overfit the data, thereby providing a more reliable measure of the model's goodness of fit.
