From the triangle, the values of α  , β and Ф are 97⁰, 45⁰ and 38⁰

Recall that the sum of angles of a straight line is 180 degrees and the sum of angles of a triangle is 180 degrees also.

using the given properties of a triangle and angles,

We have that Y + β - 180  ( sum of angles on a straight line)

where β = 135 degrees

Y = 180-135

Y = 45⁰

Also, using the same properties,

α + <EAC = 180 (sum of <s of a straight line)

α + 83 = 180

α = 97⁰

Ф = 180 - (97 + 45)

Ф = 180 -  142

In mathematics, a function appears to be a link between two sets of numbers in which each member of the first set (known as the domain) corresponds to a specific member of the second set (called the range). In other words, a function takes input from one collection and creates output from another. The variable x has frequently been used to represent inputs, whereas the variable y has been used to represent outputs. A formula or a graph can be used to represent a function. For example, the formula y = 2x + 1 depicts a functional form in which each value of x generates a unique value of y.

inverse function

\(c(x) = 55x + 25\\c(x) - 25 = 55x\\x = (c(x) - 25) / 55\\c^(-1)(x) = (x - 25) / 55\\c(x) = 55x + 25 = 2005\\55x = 1980\\x = 36\\\)

The amount that is closest to Nathan's total costs after the 15% discount and including 6% sales tax, assuming tax is applied after the discount is applied would be $624. That is option A.

The discount on sales is the amount of money that is being deducted from the original price of an item by a seller to their customers.

The original price for labor= $299.88

The original price for parts = $ 307.54

The original price for others = $ 74.71

The total original price = $682.13

The discount of on the total price = 15%.

That is;

= 15/100 × 682.13

= 10,232.95/100

= $102.32

When discount is removed from the original price;

= 682.13 - 102.32

= $579.81

When the tax is acted on the discount total sales;

= 6/100 × 579.81

= $3,478.86/100

= $34.79.

The total cost after discount and tax would be;

= 579.81 + 34.79

Answer:Faelyn should realize that her work shows that the polynomial is prime.

Explanation:

The only difference between her factors in Step 2 is that the 4 in the first group is negative, while the 4 in the second group is positive.

Rearranging the polynomial to factor it will not change the end result.

Factoring out a negative will make not only one, but both terms, in one of the binomials the opposite sign; this will not make the factors the same.

Factoring only 2x out of the first group will result in having (3x³+4x); this is not the same either.

The area of the base of the solid is equal to e^-2 - 2.

A base of a solid is the region bounded by y = e^-x, the x-axis, the y-axis, and the line x = 2.

To find the area of the base, we need to find the region that is bounded by y = e^-x, the x-axis, and the line x = 2. The x-axis and the line x = 2 act as boundaries, so we need to find the points where y = e^-x intersects these two lines. The x-axis is at y = 0, so the point of intersection is found by solving the equation:

0 = e^-x

Taking the natural logarithm of both sides, we get:

x = -ln(0) = ∞

The line x = 2 intersects y = e^-x at:

e^-x = 2

Taking the natural logarithm of both sides, we get: -x = ln(2)

And solving for x, we get: x = -ln(2)

So, the area of the base is the region bounded by x = -ln(2), x = 2, and y = e^-x. This can be found by integrating e^-x from x = -ln(2) to x = 2. The result is: A = ∫_{-ln(2)}^{2} e^-x dx = -e^-x |_{-ln(2)}^{2} = e^-2 - e^-(-ln(2)) = e^-2 - e^ln(2) = e^-2 - 2.

Therefore, the area of the base of the solid is equal to e^-2 - 2.

Answer:

h = 9 yds,       assuming his treehouse is a rectangular shape. 9 yds seems pretty high.

Step-by-step explanation:

area = bh

108 yd³ = 12 yd² x h

h = 108/12 = 9 yds

 The prism is 9 yards tall

What is the Volume of Rectangular Prism?

The area occupied inside a rectangular prism is referred to as the volume of the prism. A polyhedron with two pairs of congruent and parallel bases is referred to as a rectangular prism. It has 12 sides, 6 faces (all of which are rectangles), and 8 vertices. Given that the rectangular prism is a three-dimensional (3D) shape, the units cm3, m3, and so forth are employed to express the volume of the rectangle prism. Any polyhedron that possesses all of these qualities is referred to as a cuboid in mathematics.

Given: base of the treehouse= 12 yards²

volume of the treehouse = 108 yards³

To find : how tall is the prism ( height of the treehouse) = ?

Formula Used : The volume of a rectangular prism is calculated using the formula volume of a rectangular prism (V) = l w h,

where "l" stands for base length

"w" for base width.

"h" refers to the prism's height.

Steps for calculating the height

Step 1: The foundation area of 12 square yards has previously been specified.

Step 2: The prism's volume is 108 cubic yards

Step 3: The given rectangular prism's volume = base area x height

=> 108 cubic yards = 12 x h

=> 108/ 12 = h

=> h = 9 yards

Since , the prism is 9 yards tall

The triangle is a scalene triangle.

The measures of the three angles of a triangle are x, x+10, and 2x-6. What type of triangle must it be? The sum of the measures of the three angles in a triangle is 180 degrees, which means that:

   x + x + 10 + 2x - 6 = 180

This simplifies to,

   4x + 4 = 180,

   or 4x = 176, or x = 44

Once we have found x, we can now find the measures of the three angles of the triangle: the first angle is x, which is 44°, the second angle is x+10, which is 54°; and the third angle is 2x-6; which is 82°.

Aggregate Demand (AD) is a macroeconomic concept that represents the total demand for goods and services in an economy. The X factor in the AD equation represents exports, which are an important part of the economy.

AD is calculated by adding up the individual components of demand, which include consumer spending (C), investment spending (I), government spending (G), and net exports (X-M). The X-M component represents the difference between exports (X) and imports (M).

The X component in the equation represents exports, which are the goods and services produced domestically and sold to foreign countries. Exports are an important part of the economy as they generate income and create jobs. The M component in the equation represents imports, which are the goods and services purchased from foreign countries and consumed domestically. Imports can have a negative impact on the economy as they represent a drain on resources and can lead to a trade deficit. The X factor in the equation is used to represent exports because it is a variable that can change over time. Factors that can affect exports include exchange rates, tariffs, and global demand for certain products. If the exchange rate between two currencies changes, it can make exports more or less expensive for foreign buyers, which can affect the level of exports. Tariffs are taxes on imports, which can make domestic products more competitive in foreign markets.

Yes, the large-sample confidence interval will be valid.

A normal distribution is a type of continuous probability distribution for a real-valued random variable in statistics.

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data far from the mean.

The confidence interval will be valid regardless of the shape of the population distribution as long as the sample is large enough to satisfy the central limit theorem.

A sample is considered large when n ≥ 30.

By 'valid', it means that the confidence interval procedure has a 95% chance of producing an interval that contains the population parameter.

Charges= $400

Additional charges= $7.5 per guest

let the number of guests be x

let the total cost be y

the model for the situation is given as

y=mx+C

Step two:

given that y=1600

we can solve for x as

1600=7.5x+400

1600-400=7.5x

1200=7.5x

divide both sides by 7.5 we have

x=1200/7.5

Answer:

The total number of servings of chicken the food bank can provide = 70 servings

Step-by-step explanation:

The given information from the table are;

The number of chicken contained in the main course of a serving of food = 2

The mass of each chicken served by the food bank = 12.6 oz

The quantity of chicken the food bank has = 110.9 pounds (1,774.4 ounces of chicken)

Therefore we have;

The mass of chicken per serving = 2 × 12.6 = 25.2 oz/serving

The total number of servings of chicken the food bank can provide = (The quantity of chicken the food bank has)/(The mass of chicken per serving)

∴ The total number of servings of chicken the food bank can provide = (1,774.4 oz)/(25.2 oz/serving) ≈ 70.413

Given that the servings are in whole numbers, we have;

The total number of servings of chicken the food bank can provide = 70 servings, to the nearest whole number.

7x + 8y ≤ 200

Step-by-step explanation:

Let's say x is the number of 550-MB disks and y is the number of 650-MB disks. Then, the cost of x 550-MB disks is 7x dollars, and the cost of y 650-MB disks is 8y dollars.

The total cost cannot exceed $200, so we have:

7x + 8y ≤ 200

This inequality represents the maximum number of disks of each type that can be bought with the budget of $200.

The given sequence is neither arithmetic nor geometric. Its sigma notation is ∑(1/2n).

An arithmetic sequence is a sequence in which each term is obtained by adding a fixed number to the previous term. A geometric sequence is a sequence in which each term is obtained by multiplying the previous term by a fixed number. However, the given sequence does not have a constant difference or ratio between its terms.

To find a formula for this sequence, we can first find a common denominator for the fractions:

1/2 + 1/4 + 1/6 + ... + 1/240 = (120/240) + (60/240) + (40/240) + ... + (1/240)

We can see that each term in the sequence can be written in the form k/240, where k is a positive integer. The first term is 1/2, which is equivalent to 120/240, and the last term is 1/240.

So, the given sequence can be written as:

1/2 + 1/4 + 1/6 + ... + 1/240 = (1/240)(120 + 60 + 40 + ... + 1)

We can recognize the sum in parentheses as an arithmetic series with a first term of 120, a common difference of -20, and a last term of 1:

120 + 100 + 80 + ... + 1 = 1 + 21 + 41 + ... + 120

To find the sum of this arithmetic series, we can use the formula:

Sn = (n/2)(a1 + an)

where Sn is the sum of the first n terms, a1 is the first term, and an is the nth term.

In this case, we have:

Sn = (n/2)(120 + 1)

Sn = (n/2)(121)

Since the sum of the given sequence is (1/240) times this sum, we can write the sum as:

1/2 + 1/4 + 1/6 + ... + 1/240 = (1/240)(n/2)(121)

To find the value of n, we can set the last term of the sequence (1/240) equal to k/240, where k is a positive integer:

1/240 = k/240

k = 1

So, there is only one term in the sequence. Therefore, n = 1, and we have:

1/2 + 1/4 + 1/6 + ... + 1/240 = (1/240)(1/2)(121)

1/2 + 1/4 + 1/6 + ... + 1/240 = 121/48000
