Ok, so
Let me draw the situation here below:
So, we want to find the value of x.
For this, we have to remember that the sum of the internal angles of any triangle will always be 180°.
And we got the following angles:
A = 2x+20
B = 7x+7
C = 90
And we know that:
2x + 20 + 7x + 7 + 90 = 180°
9x + 117 = 180
We let numbers in one side of the equation and "x terms" in the other side. Like this:
9x = 63
Therefore, the value of x is 7.

A TRANSLATION OF A GRAPH is its rigid movement, vertically or horizontally. On the left is the graph of the absolute value function. On the right is its translation to a "new origin" at (3, 4). y = |x|.
What are the zeros of the function f (x) = 2 – 4sinx
The zero of the function are the roots of the function
The zero of the function is 30
How to determine the zerosThe equation of the function is given as:
\(f(x) = 2 -4\sin(x)\)
Set the function to 0
\(2 -4\sin(x) = 0\)
Subtract 2 from both sides of the equation
\(-4\sin(x) = -2\)
Divide both sides by -4
\(\sin(x) = 0.5\)
Take the arc sin of both sides
\(x = \sin^{-1}(0.5)\)
Solve for x
\(x =30\)
Hence, the zero of the function is 30

ssume all information in example 1 above and the following additional information: Actual data for job 201 is give is given belowActual shirts completed for job 201………………2,000 shirtsActual direct material cost used………………...$30,000Actual direct cost incurred……………………...$20,000Actual direct labor hours used…………………. 400 hoursActual machine hours…………………………. 240 hoursInstruction: compute the applied factory overhead and determine the total cost of job 201 under each of the five bases. A) Physical output as allocation baseDirect materials cost as allocation base Direct labor cost as allocation base Direct labor hours as allocation baseMachine hours as allocation base
The applied overhead cost for job 201 is $36,000 and total cost for job 201 under direct materials cost as allocation base is $86,000.
Allocation base is a technique utilized in accounting to designate the cost of something to its use or product to recognize the price of the finished product.
Example provides the total overhead cost at $120,000 for the period, the base data of $100,000 direct material cost and 500 direct labor hours. The base data are used to calculate the predetermined factory overhead rate, which is used to apply overhead costs to work in progress.
The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the base data. The predetermined factory overhead rate is multiplied by the actual activity in the allocation base to obtain the applied overhead cost.
Direct materials cost as allocation base $30,000 is the actual direct material cost used in job 201. The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the direct material cost, which is $120,000/$100,000=120%.
The applied overhead cost for job 201 is $30,000*120% = $36,000.
Total cost for job 201 under direct materials cost as allocation base is $30,000+$20,000+$36,000 = $86,000.
-Direct labor cost as allocation base:
The actual direct labor cost used in job 201 is $20,000. The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the direct labor cost, which is $120,000/$100,000=120%.
The applied overhead cost for job 201 is $20,000*120% = $24,000.
Total cost for job 201 under direct labor cost as allocation base is $30,000+$20,000+$24,000 = $74,000.
-Direct labor hours as allocation base:
The actual direct labor hours used in job 201 is 400 hours.
The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the direct labor hours, which is $120,000/500 hours = $240 per hour.The applied overhead cost for job 201 is $240*400 hours = $96,000.
Total cost for job 201 under direct labor hours as allocation base is $30,000+$20,000+$96,000 = $146,000.
-Physical output as allocation base: The actual output in units completed for job 201 is 2,000 shirts.
The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the output in units, which is $120,000/10,000 units = $12 per unit.
The applied overhead cost for job 201 is $12*2,000 units = $24,000.Total cost for job 201 under physical output as allocation base is $30,000+$20,000+$24,000 = $74,000.
-Machine hours as allocation base: The actual machine hours used in job 201 is 240 hours.
The predetermined factory overhead rate is calculated by dividing the total overhead cost for the period by the machine hours, which is $120,000/5,000 hours = $24 per hour.
The applied overhead cost for job 201 is $24*240 hours = $5,760.
Total cost for job 201 under machine hours as allocation base is $30,000+$20,000+$5,760 = $55,760.

A merchant has 1500 kg of sugar part of which he sells at 8% profit and the rest at 18% profit. He gains 14% on the whole. The quantity sold at 18% profit is
Answer:
900 kg
Step-by-step explanation:
Let's assume the cost price (C.P.) of sugar is Rs. x per kg.
The total quantity of sugar is 1500 kg.
Let the quantity of sugar sold at 8% profit be represented by y kg.
The quantity of sugar sold at 18% profit would then be (1500 - y) kg.
Using the rule of alligation, we can set up the following proportion:
(8% profit) y kg
-------------- = ------
(18% profit) (1500 - y) kg
Simplifying the proportions, we find that the difference in percentages is 4% (18% - 14% = 4%) and 6% (14% - 8% = 6%).
The ratio of these differences is 2:3.
This means that for every 2 kg of sugar sold at 8% profit, 3 kg of sugar is sold at 18% profit.
Since y represents the quantity sold at 8% profit (2 kg), we can calculate the quantity sold at 18% profit (3 kg) as follows:
(2 kg) * (3/2) = 3 kg
Therefore, the quantity sold at 18% profit is 900 kg.

Write a formula for the perimeter of the rectangle in terms of its length, l.
a formula for the perimeter of the rectangle in terms of its length, l will be given as l = P / 2 - b.
We know that the perimeter of rectangle is given by:
Perimeter ( P ) = 2 ( l + b )
Now, we need to represent this formula in terms of length that is l.
So, we get that:
P = 2 l + 2 b
Now subtract 2 b from both the sides:
P - 2 b = 2 l + 2 b - 2 b
P - 2 b = 2 l
2 l = P - 2 b
Divide both the sides by 2:
2 l / 2 = (P - 2 b) / 2
l = P / 2 - b
Therefore, we get that, a formula for the perimeter of the rectangle in terms of its length, l will be given as l = P / 2 - b.

The equation of the exponential regression is y = 17100\(e^{-0.194x}\) and the value of a car after 12 years is $1667
What is an exponential regression?It is a model that explains processes that experiences growth at a double rate. It is used for situations where the growth begins slowly but rapidly speeds up without bounds or where the decay starts rapidly but slows down to get to zero.
Given that, the given table shows the value of a car over time that was purchased for 14100 dollars, where x is years and y is the value of the car in dollars.
We need to find the exponential regression equation for this set of data,
We know that,
The exponential regression equation is : y = A₀eᵃˣ
Where A₀ is the coefficient of exponential regression and a is the constant.
For x = 0, the value of y will be $17100.
Therefore,
17100 = A₀e⁰
A₀ = 17100
Therefore, the equation will be =
y = 17100eᵃˣ
Find for a,
For x = 1, the value of y will be $14090.
14090 = 17100eᵃ
eᵃ = 14090/17100
Taking ln both sides, then we have,
a lne = -0.194
a = -0.194
Therefore, the exponential regression equation for this set of data is :
y = 17100\(e^{-0.194x}\)
Finding the value of the car, after 12 years =
y = 17100\(e^{-0.194(12)\)
y = 1667
Hence, the equation of the exponential regression is y = 17100\(e^{-0.194x}\) and the value of a car after 12 years is $1667

Verify the given linear approximation at a = 0. Then determine the values of x for which the linear approximation is accurate to within 0.1. (Enter your answer using interval notation. Round your answers to three decimal places.) 1/((1 + 9x)^4) ≈ 1 − 36x
Answer:
Part 1)
See Below.
Part 2)
\(\displaystyle (-0.179, -0.178) \cup (-0.010, 0.012)\)
Step-by-step explanation:
Part 1)
The linear approximation L for a function f at the point x = a is given by:
\(\displaystyle L \approx f'(a)(x-a) + f(a)\)
We want to verify that the expression:
\(1-36x\)
Is the linear approximation for the function:
\(\displaystyle f(x) = \frac{1}{(1+9x)^4}\)
At x = 0.
So, find f'(x). We can use the chain rule:
\(\displaystyle f'(x) = -4(1+9x)^{-4-1}\cdot (9)\)
Simplify. Hence:
\(\displaystyle f'(x) = -\frac{36}{(1+9x)^{5}}\)
Then the slope of the linear approximation at x = 0 will be:
\(\displaystyle f'(1) = -\frac{36}{(1+9(0))^5} = -36\)
And the value of the function at x = 0 is:
\(\displaystyle f(0) = \frac{1}{(1+9(0))^4} = 1\)
Thus, the linear approximation will be:
\(\displaystyle L = (-36)(x-(0)) + 1 = 1 - 36x\)
Hence verified.
Part B)
We want to determine the values of x for which the linear approximation L is accurate to within 0.1.
In other words:
\(\displaystyle \left| f(x) - L(x) \right | \leq 0.1\)
By definition:
\(\displaystyle -0.1\leq f(x) - L(x) \leq 0.1\)
Therefore:
\(\displaystyle -0.1 \leq \left(\frac{1}{(1+9x)^4} \right) - (1-36x) \leq 0.1\)
We can solve this by using a graphing calculator. Please refer to the graph shown below.
We can see that the inequality is true (i.e. the graph is between y = 0.1 and y = -0.1) for x values between -0.179 and -0.178 as well as -0.010 and 0.012.
In interval notation:
\(\displaystyle (-0.179, -0.178) \cup (-0.010, 0.012)\)
At noon, a barista notices she has $20 in her tip jar. If she makes an average of $0.50 from each customer, how much will she have in her tip jar if she serves n more customers during her shift
Answer:
She has $20 + $0.50n in her tip jar.
Step-by-step explanation:
Amount in tip jar at noon = $20
Average amount made from each customer = $0.50
Number of additional customers served after noon = n
Therefore, we have:
Additional amount made after noon = Average amount made from each customer * Number of additional customers served after noon = $0.50 * n = $0.50n
Amount in tip jar = Amount in tip jar at noon + Additional amount made after noon = $20 + $0.50n
Therefore, she has $20 + $0.50n in her tip jar.

Brianna made 9 1/4 bags of popcorn for a movie night with some friends. Together they ate 4 bags of it. How much popcorn was left?
There were 5 1/4 bags of popcorn left after eating 4 bags.
To find out how much popcorn was left after eating 4 bags, we need to subtract the amount eaten from the total amount Brianna made.
Brianna made 9 1/4 bags of popcorn, which can be represented as a mixed number. To perform calculations, let's convert it to an improper fraction:
9 1/4 = (4 * 9 + 1) / 4 = 37/4
Now, let's subtract the 4 bags eaten from the total:
37/4 - 4
To subtract fractions, we need a common denominator. The common denominator of 4 and 1 is 4. Therefore, we can rewrite the expression as:
37/4 - 4/1
Now, let's find a common denominator and subtract the fractions:
37/4 - 16/4 = (37 - 16) / 4 = 21/4
The result is 21/4, which is an improper fraction. Let's convert it back to a mixed number:
21/4 = 5 1/4
Therefore, there were 5 1/4 bags of popcorn left after eating 4 bags.

ohms.
The electrical resistance varies directly as the square of the voltage and inversely as the electric power, and the equation that relates them isR ∝ V²/PR = kV²/PR = V²/P. This relationship can be used to calculate the electrical resistance of the wire or component for any given voltage and power.
The electrical resistance is the measure of the difficulty in passing electric current through a wire or an electrical component. It depends on various factors, such as the material, dimensions, and temperature of the wire.The given statement says that the electrical resistance varies directly as the square of the voltage and inversely as the electric power.
In mathematical terms, this relationship can be expressed as R ∝ V²/PR = kV²/P where R is the electrical resistance, V is the voltage, P is the electric power, and k is the constant of proportionality. The constant k depends on the material, dimensions, and temperature of the wire or component.
The given statement implies that the constant k is the same for the given wire or component, and it is not affected by the voltage or the power.To find the value of k, we can use the given values of V, P, and R.
According to the statement, if the voltage is 20 volts and the electric power is 5 watts, then the electrical resistance is 80 ohms. Therefore,R = kV²/PR = k(20²)/5R = 400k/5R = 80 ohms
Substituting the value of R in the equation, we get80 = 400k/5k = (80 x 5)/400k = 1. Therefore, the equation that relates the electrical resistance, voltage, and power isR = V²/PThe constant of proportionality k is 1 for the given wire or component.
Therefore, the electrical resistance varies directly as the square of the voltage and inversely as the electric power, and the equation that relates them isR ∝ V²/PR = kV²/PR = V²/P. This relationship can be used to calculate the electrical resistance of the wire or component for any given voltage and power.
