Answer:
61°
Step-by-step explanation:
We have to take the arcs at P to mean angles RPW and MPW are congruent. That means each is 58°/2 = 29°. Angle PMR is the other acute angle in right triangle PMW, so it will be the complement of 29°.
∠PMR = 90° -29° = 61°

Complete the following statement. Use the integers that are closest to the number in the middle. < 82 <
Answers
The integers that are closest to the number in the middle in the inequality x < √82 < y are x = 9 and y = 11.
To find the integers x and y that satisfy the inequality x < √82 < y, we need to find the two integers that are closest to the square root of 82.
First, we know that the perfect square that is less than 82 is 81, which is equal to 9². Therefore, we can say that 9 < √82.
Next, we need to find the next closest integer to the square root of 82. To do this, we can calculate the square of 10 and the square of 11, which are 100 and 121, respectively. Since 82 is closer to 81 than to 100, we can say that √82 < 10.5.
Therefore, x = 9 and y = 11 are the integers that satisfy the inequality x < √82 < y.

From sin(3θ) = −1/sqrt2, Solve for 3θ on the interval [0,2pi). Enter your answers on a comma separated list.
3θ=
θ=
Answers
We cannot provide a single value for θ in the range [0, 2π).
What is the equivalent expression?
Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.
To solve for 3θ in the equation sin(3θ) = -1/√2, we need to find the values of θ that satisfy the equation.
Find the inverse sine of both sides to isolate 3θ:
arcsin(sin(3θ)) = arcsin(-1/√2)
3θ = arcsin(-1/√2)
Evaluate the inverse sine on the right side using a calculator or reference table.
The principal value of arcsin(-1/√2) is -π/4.
3θ = -π/4
To find θ, divide both sides by 3:
θ = (-π/4) / 3
Now, let's find the value of θ within the interval [0, 2π):
Since (-π/4)/3 is negative, we can add 2π repeatedly to get the equivalent angle within the desired interval:
θ = (-π/4) / 3 + 2π
θ = (-π/4) / 3 + 2π + 2π
θ = (-π/4) / 3 + 2π + 2π + 2π
...
Continue adding 2π until θ is within the range [0, 2π).
θ = (-π/4) / 3 + 2π + 2π + 2π + ...
To simplify the expression, we can express -π/4 as -2π/8:
θ = (-2π/8) / 3 + 2π + 2π + 2π + ...
Now, let's simplify further:
θ = (-2π/24) + 2π + 2π + 2π + ...
θ = (-2π/24) + (48π/24) + (48π/24) + (48π/24) + ...
Combining like terms:
θ = (46π/24) + (48π/24) + (48π/24) + ...
Simplifying:
θ = (94π/24) + (48π/24) + (48π/24) + ...
θ = (94π + 48π + 48π + ...) / 24
We can see that the expression (94π + 48π + 48π + ...) will keep increasing by adding 48π repeatedly.
Therefore, there is no specific value for θ within the range [0, 2π). Instead, θ can take infinitely many values.
Hence, we cannot provide a single value for θ in the range [0, 2π).

As x -> -∞, f(x) -> -2.As x -> ∞, f(x) -> 0.How to obtain the features of the function?The range of a function is given by the set of all the output values that compose the function.
For the definition to the left of x = 1, the minimum and maximum values are given as follows:
Minimum: y = -2 as x goes to negative infinite -> horizontal asympote.Maximum: y = 7 as x = 1.For the definition to the right of x = 1, the minimum and maximum values are given as follows:
Minimum: y = 0 as x -> infinity -> horizontal asymptote.Maximum: y = 7 to the right of 1.Hence the range is given as follows:
(-2,7].

What is an integer?
Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers. The boldface Z is a common way to represent the set of integers in mathematical terms.
When we conduct an operation on set members and always obtain a set member, the set is said to be closed under that operation. As a result, a set either possesses closure regarding a particular operation or it does not. A set is said to satisfy a closure property if it is closed by an operation or set of operations. A closure property is typically introduced as a hypothesis, known as the axiom of closure.

intercepts: (0, 5/2) or (-5, 0)arbitrary point: (7, 6)Step-by-step explanation:
You want two methods of choosing points on the line with slope 1/2 through A(-1, 2).
InterceptsWriting the equation in standard form, we can find the x- and y-intercepts. To get there, we can start from point-slope form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -2 = 1/2(x -(-1)) . . . . . using given slope and point
2y -4 = x +1 . . . . . . . . . . multiply by 2
x -2y = -5 . . . . . . . . . . . . add -1 -2y
Setting x=0 tells us the y-intercept is ...
0 -2y = -5
y = -5/-2 = 5/2
So, the y-intercept is (0, 5/2).
Setting y=0 tells us the x-intercept is ...
x -2(0) = -5
x = -5
So, the x-intercept is (-5, 0).
Arbitrary pointIt will be convenient to choose an arbitrary y-value to find another point on the line. We can pick y = 6, for example, Then the corresponding x-value is ...
x -2y = -5
x = -5 +2y = -5 +2(6) = 7
Another point on the line is (7, 6).
__
Additional comment
If we were to choose an arbitrary value for x, we would want it to be odd, so the corresponding y-value would be an integer. We chose to pick an arbitrary value of y so we didn't have to worry about how to make the x-value an integer.

Given: KL ║ NM , LM = 45, m∠M = 50° KN ⊥ NM , NL ⊥ LM Find: KL, KM
Answers
From the question, , KL ≈ 34.32 and KM ≈ 55.81.
How to find KL and KMSince KL ║ NM, we have m∠KLM = m∠M = 50° (alternate interior angles)
Also, KN ⊥ NM and NL ⊥ LM, so KNL and LNM are right triangles.
From KNL, we have:
sin(50°) = KN/KL
KN = KL sin(50°)
From LNM, we have:
LM + MN = 45
MN = KL cos(50°)
Since KN ⊥ NM, we have:
KM = KN + MN
KM = KL sin(50°) + KL cos(50°)
KM = KL(sin(50°) + cos(50°))
We can solve for KL using MN and LM:
MN = KL cos(50°)
MN = 45 - LM
KL cos(50°) = 45 - LM
KL = (45 - LM) / cos(50°)
Substituting into the equation for KM:
KM = [(45 - LM) / cos(50°)] (sin(50°) + cos(50°))
Simplifying, we get:
KM ≈ 55.81
And substituting back into the equation for KL:
KL ≈ 34.32
Therefore, KL ≈ 34.32 and KM ≈ 55.81.

Answers
By using simultaneous linear equation the results obtained are-
Number of small boxes = 6 and number of large boxes = 3
What is simultaneous linear equation?
At first it is important to know about linear equation
Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.
A one degree equation is known as linear equation.
Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.
Let the number of small boxes purchased be x, and the number of large boxes purchased be y.
Each small box has 200 nails and each large box has 600 nails.
Total number of nails = 3000
\(200x +600y = 3000\\200(x+ 3y)=3000\\x + 3y = \frac{3000}{200}\\x + 3y = 15\) .............. (1)
The contractor bought twice as many small boxes as large boxes
So,
\(x = 2y\\x - 2y = 0............(2)\)
The equations are solved graphically. The graph has been attached.
