[tex]26 sin 58°[/tex] is the expression that represents the length of segment PR.

What is Length?

The word "length" is used to describe an object's size or the separation between two points. The length of an object or the separation between two points is measured by its length. It is employed to determine an object's size or the separation between two points.

Since triangle JKL and triangle PQR are similar, we can use the similarity ratios to find the length of PR.

We know that the ratio of PR to JK is the same as the ratio of PQ to JL. We know that [tex]PQ = 26 and JL = 26 + 13 = 39[/tex], so the ratio is [tex]26/39[/tex].

So, [tex]PR = (26/39) * 13 = 26sin( JL/2) = 26sin58°[/tex]

So the answer is [tex]26 sin 58°[/tex]

Is it possible to draw a triangle the length of whose sides are 2.5 cm 4.2 cm 8 cm?

Answers

No, it is not possible to draw a triangle with side lengths of 2.5 cm, 4.2 cm, and 8 cm.

The triangle inequality theorem states that for any triangle, the sum of the lengths of the two shorter sides must be greater than the length of the longest side.

In other words, for a triangle with sides of lengths a, b, and c, where c is the longest side, the following must be true: a + b > c, b + c > a, and a + c > b.

In the case of the triangle with side lengths of 2.5 cm, 4.2 cm, and 8 cm, the sum of the lengths of the two shorter sides (2.5 cm + 4.2 cm) is 6.7 cm, which is less than the length of the longest side (8 cm).

Therefore, it is not possible to form a triangle with these side lengths, as the triangle inequality theorem is not satisfied.

So far, Leo has put together 40% of his 500-piece puzzle. How many puzzle pieces has Leo put together?

Answers

Answer:

200

Step-by-step explanation:

Portions of quantities can be represented as percentages and decimals, which can help solve different types of questions.

Multiplying Decimals

To find any percent of a quantity, you can multiply the quantity by the percentage as a decimal. We can convert percentages to decimals easily. By moving the decimal point 2 places to the left, we can change 40% into a decimal. So, 40% is equal to 0.4. Now, multiply this by 500.

500 * 0.4 = 200

So, Leo has put together 200 pieces.

Multiples of 10

Since 40% is a multiple of 10, we can solve using another method. It is easy to find 10% of any quantity, just move the decimal point 1 place to the left. So, 10% of 500 is 50.

Then, since 40 is 4 times 10, we can say that 40% of 500 is 4 times 10% of 500.

50 * 4 = 200

This proves that Leo has done 200 pieces.

evaluate the integral (3 to 1) of x^4 (ln x 2)^2 dx

Answers

The definite integral is [tex]& \frac{243}{5}(\ln 3)^2-\frac{2}{5}\left[\ln 3\left(\frac{243}{5}\right)-\frac{243}{25}\right]-\frac{2}{125}[/tex].

The integral is [tex]$\int_1^3 x^4(\ln x)^2 d x$[/tex]

First evaluate indefinite integral, [tex]$\int x^4(\ln x)^2 d x$[/tex]

The definite integral of a real-valued function f(x) with respect to a real variable x on an interval [a, b] is expressed as [tex]\int_a^b f(x) d x=F(b)-F(a)[/tex]

Here,

∫ = Integration symbol

a = Lower limit

b = Upper limit

f(x) = Integrand

dx = Integrating agent

Thus, ∫ab f(x) dx is read as the definite integral of f(x) with respect to dx from a to b.

Indefinite integrals are implemented when the boundaries of the integrand are not specified.

Use integration by parts:

[tex]$\int u d v=u v-\int v d u$[/tex]

Let [tex]$u=(\ln x)^2$[/tex] and [tex]$a v=x^4 d x$[/tex]

This implies [tex]$d u=\frac{2(\ln x)}{x} d x$[/tex] and [tex]$v=\int x^4 d x=\frac{x^5}{5}$[/tex]

Equation (1) becomes,

[tex]$$\begin{aligned}& \int x^4(\ln x)^2 d x=(\ln x)^2 \frac{x^5}{5}-\int \frac{x^5}{5} \times \frac{2(\ln x)}{x} d x \\& \int x^4(\ln x)^2 d x=(\ln x)^2 \frac{x^5}{5}-\frac{2}{5} \int x^4 \ln x d x\end{aligned}$$[/tex]

Again, use integration by parts to evaluate [tex]$\int x^4 \ln x d x$[/tex]

Let [tex]$u=\ln x, d v=x^4 d x$[/tex]

This implies [tex]$d u=\frac{1}{x}$[/tex] and  [tex]$v=\int x^4 d x=\frac{x^5}{5}$[/tex]

Let [tex]$u=\ln x, d v=x^4 d x$[/tex]

This implies [tex]d u=\frac{1}{x}$[/tex] and [tex]$v=\int x^4 d x=\frac{x^5}{5}$[/tex]

[tex]$$\begin{aligned}\int x^4 \ln x d x & =\ln x\left(\frac{x^5}{5}\right)-\int\left(\frac{x^5}{5}\right) \frac{1}{x} d x \quad \text { since } \int u d v=u v-\int u d u \\& =\ln x\left(\frac{x^5}{5}\right)-\frac{1}{5} \int x^4 d x \\& =\ln x\left(\frac{x^5}{5}\right)-\frac{x^5}{25}\end{aligned}$$[/tex]

From equation (2),

[tex]$$\int x^4(\ln x)^2 d x=(\ln x)^2 \frac{x^5}{5}-\frac{2}{5}\left[\ln x\left(\frac{x^5}{5}\right)-\frac{x^5}{25}\right]$$[/tex]

The required definite integral is,

[tex]$$\begin{aligned}\int_1^3 x^4(\ln x)^2 d x & =\left[(\ln x)^2 \frac{x^5}{5}-\frac{2}{5}\left[\ln x\left(\frac{x^5}{5}\right)-\frac{x^5}{25}\right]\right]^3 \\& =\left[(\ln 3)^2 \frac{3^5}{5}-\frac{2}{5}\left[\ln 3\left(\frac{3^5}{5}\right)-\frac{3^5}{25}\right]\right]-\left[(\ln 1)^2 \frac{1^5}{5}-\frac{2}{5}\left[\ln 1\left(\frac{1^5}{5}\right)-\frac{1^5}{25}\right]\right] \\& =\frac{243}{5}(\ln 3)^2-\frac{2}{5}\left[\ln 3\left(\frac{243}{5}\right)-\frac{243}{25}\right]-\frac{2}{125}\end{aligned}$$[/tex]

Therefore, the required definite integral is [tex]& =\frac{243}{5}(\ln 3)^2-\frac{2}{5}\left[\ln 3\left(\frac{243}{5}\right)-\frac{243}{25}\right]-\frac{2}{125}[/tex].

The optimal values of x and y to maximize the profit are 10 and 10, respectively, and the maximum profit is $200.

Let X and Y represent the number of units of product A and B that we want to produce. We want to maximize the profit, so our objective function is:

Profit = 10x + 15y

The constraints are:

X + Y ≤ 20

2X + Y ≤ 30

X ≥ 0, Y ≥ 0

To find the optimal values of x and y, we must first solve the system of equations. By subtracting the first equation from the second equation, we get:

X = 10

Substituting this value into the first equation, we get:

Y = 10

Now that we have found the values of x and y, we can plug them into the objective function to find the maximum profit:

Profit = 10(10) + 15(10) = 200

Determine the limit by sketching an appropriate graph. lim: x ->-7 from : f(x), where f(x) = S-3x +0 for x <7 and 5x + 1 for x >=7 a. 1 b. -21 c. 36 d. 2

Answers

To determine the limit of f(x) as x approaches -7, we need to analyze the behavior of the function as x gets closer and closer to -7.

Since f(x) is defined differently for x < 7 and x >=7, we need to look at both cases separately.

For x < 7, f(x) = -3x + 0

For x >= 7, f(x) = 5x + 1

If we substitute x = -7 into the first equation, we get f(-7) = -3(-7) + 0 = 21

If we substitute x = -7 into the second equation, we get f(-7) = 5(-7) + 1 = -36

We can see that the function is defined differently for x < 7 and x >=7, and it does not have the same value when x = -7.

Therefore, the limit of f(x) as x approaches -7 does not exist (DNE).

A graph of f(x) with two different lines for x<7 and x>=7, one with slope -3 and y-intercept 0, the other with slope 5 and y-intercept 1. The two lines do not intersect at x = -7, this illustrates the DNE limit.

Answers

Difference in the weekly earnings of Dana and Monique is $127.5.

What is Multiplication?

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

Dana :

Number of days Dana grooms dogs = 4 days a week

Number of dogs Dana grooms in a day = 15 dogs

Number of dogs Dana grooms in a week = 15 × 4 = 60 dogs

Earning of Dana per dog = $12.75

Earnings of Dana in a week = 60 × $12.75 = $765

Monique :

Number of days Monique grooms dogs = 5 days a week

Number of dogs Monique grooms in a day = 10 dogs

Number of dogs Monique grooms in a week = 10 × 5 = 50 dogs

Earning of Monique per dog = $12.75

Earnings of Monique in a week = 50 × $12.75 = $637.5

Difference in their earnings = $765 - $637.5 = $127.5

Camille is sixty-six inches tall. This is twenty inches less than two times Mindy's height. How tall is Mindy ?

Answers

Let's call Mindy's height "M". According to the problem, we know that:

Camille's height = 66 inches

Camille's height = 2 * Mindy's height - 20 inches

We can substitute the first equation into the second equation to solve for Mindy's height:

66 inches = 2 * M - 20 inches

We can add 20 inches to both sides of the equation to get:

66 inches + 20 inches = 2 * M

This gives us:

86 inches = 2 * M

To find Mindy's height, we can divide both sides of the equation by 2:

M = 86 inches / 2

So Mindy is 43 inches tall.

Answer:

Mindy is  46 inches

Step-by-step explanation:

Let m = Mindy's height

66 = 2m - 20  Add 20 to both sides

66 + 20 = 2m - 20 + 20

86 = 2m  Divide both sides by 2

[tex]\frac{86}{2}[/tex] = [tex]\frac{2m}{2}[/tex]

46 = m

CLEAR CHECK

115<−225 because 11 5 is located to the right of −225 on the number line.



115 > −135 because 115 is located to the right of −135 on the number line.



−225 < −135 because −135 is located to the right of −225 on the number line.



115 > −225 because 115 is located to the right of −225 on the number line.

Answers

The statement 115 < -225 because 115 is located to the right of -225 on the number line is not true.

What is a number line?

The horizontal straight lines in mathematics known as number lines are where integers are arranged in equal intervals. A number line can be used to represent every number in a sequence. This line continues forever at both ends.

On a number line as we go from left to right the numbers increase. For the given numbers, 115 > -135> -225 as 115 is located on the right of the number line.

Hence, statement one 115 < -225 because 115 is located to the right of -225 on the number line is not true.
