The value of ∠ GPY, given the angle measures on the figure, can be found to be 118 °
How to find the angle ?The angles ∠ GPY and ∠ KPR are congruent, which means that they are the same.
The angle ∠ GPY can therefore be found by equating both angles to themselves:
8 p + 94 = 5 p + 103
Collect like terms ;
8 p - 5 p = 103 - 94
3 p = 9
p = 9 / 3
p = 3

$
(c) Form the profit function P(x) from the cost and revenue functions.
Find maximum profit.
$
(d) What price will maximize the profit? (Round your answer to the nearest cent.)
$
(a) The break-even points are approximately 1,581 and 2,809 units produced.
(b) The maximum revenue is approximately $2,088,931.47.
(c) P(x) = -5/9x² + 919x - 49,400
(d) The price that will maximize the profit is approximately $1,829.17 per unit.
What is the algebraic equations?An algebraic expression is when we use numbers and words in solving a particular mathematical question.
(a) To find the break-even points, we need to find the values of x at which the total revenue equals the total cost. The total revenue is the product of the selling price and the number of units sold, while the total cost is the sum of the fixed cost and the variable cost per unit multiplied by the number of units sold. Thus, we have:
Total revenue = Selling price × Number of units sold = (2148 - 5/9x)x
Total cost = Fixed cost + Variable cost per unit × Number of units sold = 49,400 + (49x/9 + 222)x
Setting the total revenue equal to the total cost, we get:
2148x - 5/9x² = 49,400 + (49x/9 + 222)x
Multiplying both sides by 9, we get:
19332x - 5x² = 445,110
Simplifying, we get:
5x²- 19332x + 445,110 = 0
Using the quadratic formula, we get:
x = (19332 ± sqrt(19332² - 4(5)(445,110))) / (2(5))
x ≈ 2808.6 or x ≈ 1581.4
Hence, the break-even points are approximately 1,581 and 2,809 units produced.
(b) The revenue function is given by:
R(x) = (2148 - 5/9x)x
To find the maximum revenue, we can take the derivative of the revenue function with respect to x, set it equal to zero, and solve for x:
R'(x) = 2148 - 10/9x = 0
x = 19332/10 ≈ 1933.2
Substituting this value of x into the revenue function, we get:
R(1933.2) ≈ $2,088,931.47
Hence, the maximum revenue is approximately $2,088,931.47.
(c) The profit function P(x) is given by:
P(x) = R(x) - C(x) = (2148 - 5/9x)x - (49,400 + (49x/9 + 222)x)
Simplifying, we get:
P(x) = -5/9x² + 919x - 49,400
(d) To find the maximum profit, we can take the derivative of the profit function with respect to x, set it equal to zero, and solve for x:
P'(x) = -10/9x + 919 = 0
x = 8265
Substituting this value of x into the profit function, we get:
P(8265) ≈ $1,077,927.78
Therefore, the maximum profit is approximately $1,077,927.78.
To find the price that will maximize the profit, we need to substitute the value of x into the selling price function:
Selling price = 2148 - 5/9x = 2148 - 5/9(8265) ≈ $1,829.17
Hence, the price that will maximize the profit is approximately $1,829.17 per unit.

Find dz/dt using chain rule
Using the chain rule, the value for dz/dt is obtained as [tex]dz/dt = 2(2t + (4 - t^2)e^{(4-t^2)}) ((1 - t)e^{(4-t^2)})[/tex].
What is chain rule?
The chain rule is the formula used to determine the derivative of a composite function, such as cos 2x, log 2x, etc. Another name for it is the composite function rule. Only composite functions are subject to the chain rule.
To find dz/dt using the chain rule, we need to differentiate each term of z with respect to t, then multiply by the derivative of the inner function with respect to t.
First, we have -
x = 2t
Taking the derivative with respect to t, we get -
dx/dt = 2
Next, we have -
y = 4 - t²
Taking the derivative with respect to t, we get -
dy/dt = -2t
Using the chain rule, we have -
[tex]dz/dt = (x + y)e^y \times (\frac{dx}{dt} + \frac{dy}{dt}e^y)[/tex]
Substituting x and y into this equation, we get -
[tex]dz/dt = (2t + (4-t^2))e^{(4-t^2)} \times ((2 - 2t) e^{(4-t^2)})[/tex]
Simplifying this expression, we get -
[tex]dz/dt = 2(2t + (4 - t^2)e^{(4-t^2)}) ((1 - t)e^{(4-t^2)})[/tex]

As a result, y = -x + 1/2 is the equatiοn οf the tangent line tο the curve x² + y² = (2x² + 2y² - x)² at the pοsitiοn (0,1/2).
What is equatiοn?An equatiοn in mathematics is a claim that twο mathematical expressiοns are equivalent. An equatiοn has an equal sign, typically has οne οr mοre factοrs, and can be sοlved fοr by applying algebraic οr numerical techniques. Equatiοns are used tο represent real-wοrld phenοmena, resοlve issues, and make predictiοns in many branches οf mathematics, science, and engineering.
given:
We must first use implicit differentiatiοn tο determine the derivative οf the curve in οrder tο determine the equatiοn οf the tangent line tο the curve at the pοsitiοn (0,1/2).
By taking the derivative οf the equatiοn's twο sides with regard tο x, we arrive at:
dy/dx = 2x + 2y
(2x² + 2y²- x) * (4x - 1) (4x - 1)
When we sοlve fοr dy/dx and simplify this equatiοn, we get:
[(1 - 4x)(2x + 2y)] Equals dy/dx / [4(2x² + 2y² - x) - 2y(1 - 4x)]
The slοpe οf the tangent line at the pοint (0,1/2) can nοw be calculated by plugging in the numbers x = 0 and y = 1/2:
dy/dx = [(1 - 4(0))
(2(0) + 2(1/2))] / [4(2(0)² + 2(1/2)² - 0) - 2(1/2)(1 - 4(0))] = -1
Therefοre, the tangent line's slοpe at the pοsitiοn (0,1/2) is negative οne. We can use the pοint-slοpe fοrm οf a line tο determine the equatiοn οf the tangent line:
where (x1,y1) is the tangency pοint and m is the inclinatiοn οf the tangent line. When we enter the numbers we have, we οbtain:
y - 1/2 = -1(x - 0) (x - 0)
When we simplify this sοlutiοn, we οbtain:
y = -x + 1/2
As a result, y = -x + 1/2 is the equatiοn οf the tangent line tο the curve x² + y2 = (2x² + 2y² - x)² at the pοsitiοn (0,1/2).

Since the function has a phase of 2, we can concentrate on the range from 3/2 to 3/2. We possess
=> f(−3/2) = 5 cos(−3/2) ≈ 4.515
=> f(−π) = 5 cos(−π) = −5
=> f(−1/2) = 5 cos(−1/2) ≈ 4.045

The length of a radius of a circle, measured in feet, is represented by the expression z + 3.6. The diameter of the circle is 11 4/5 ft.
What is the value of z?
Enter your answer as a decimal or mixed number in simplest form in the box.
Answer:
Step-by-step explanation:
The diameter of the circle is twice the length of the radius, so we can write:
2r = d
where r is the radius and d is the diameter.
Substituting the given diameter of 11 4/5 ft, we get:
2r = 11 4/5 ft
To find the length of the radius, we can divide both sides by 2:
r = (11 4/5) / 2
r = 5 9/10 ft
We also know that the length of the radius is z + 3.6, so we can set up the equation:
z + 3.6 = 5 9/10
Subtracting 3.6 from both sides, we get:
z = 5 9/10 - 3.6
z = 2 3/10
Therefore, the value of z is 2 3/10 or 2.3 as a decimal.

The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years IS 0.528.
The binomial probability:The binomial probability formula is used to calculate the probability of getting exactly k successes in n independent trials, where each trial has only two possible outcomes (success or failure) and the probability of success is denoted as p. The formula is:
[tex]P(X=k) = C(n,k)\times p^k\times(1-p)^{(n-k)[/tex]Here we have
39.6% of consumers believe that cash will be obsolete in the next 20 years.
Let p be the probability that a consumer believes that cash will be obsolete
=> p = 39.6% or 0.396.
Then, the probability that a consumer does not believe that cash will be obsolete is q = 1 - p = 0.604.
We need to find the probability that less than 3 of the selected consumers believe that cash will be obsolete.
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)
Using the binomial probability formula, we have:
[tex]P(X = k) = C(n,k) \times p^k\times q^{(n-k)[/tex]
=> P(X = 0) = C(6, 0) × (0.396)⁰ × (0.604)⁶ = 0.048
=> P(X = 1) = C(6, 1) × (0.396)¹ × (0.604)⁵ = 0.18
=> P(X = 1) = C(6, 2) × (0.396)² × (0.604)⁴ = 0.3

Find the sum of the following arithmetic series:
Answer:
19107
Step-by-step explanation:
First, we need to find the common difference (d), which we can find by subtracting two consecutive terms. Thus, we can do d = 1 - (-3) = 4.
Now, we need to know how many terms are in the arithmetic series. We can find the number using nth term formula, which is
[tex]a_{n}=a_{1}+(n-1)*d[/tex], where a1 is the first term, n is the term position (e.g., 1st, 2nd).
Although we don't know the term position of 389, we can still plug it into the formula and solving for n will reveal it's term number and the total number of sums in the sequence:
[tex]389=-3+(n-1)*4\\392=(n-1)*4\\392=4n-4\\396=4n\\99=n[/tex]
Now, we can find the sum using the sum formula, which is
[tex]S_{n}=n/2*(a_{1}+a_{n})[/tex]
Sn can become S99 since there are 99 terms and we can let an = a99, which we know is 389.
Now, we must solve for S99:
[tex]S_{99}=\frac{99}{2}*(-3+389)\\ S_{99}=\frac{99}{2}*(386)\\ S_{99}=19107[/tex]

Step-by-step explanation:
What is the total cost of a $713 tablet computer that is on sale at 11% off if the local sales tax rate is 7%?
The total cost of the tablet is S
(Round to two decimal places as needed.)
The total cost of the tablet is $684.48
How to calculate the total cost of the tablet?The first step is to write out the parameters given in the question
The cost of the tablet computer is $713
The tablet computer is on sale at 11%
Next is to multiply the total cost by the sales percent
11/100 × 713
= 0.11 × 713
= 78.43
= 713 - 78.43
= 634.57
The local sales tax rate is 7%
= 7/100 × 713
= 0.07 × 713
= 49.91
The total cost can be calculated as follows
= 49.91 + 634.57
= 684.48
Hence the total cost of the tablet is $684.48
