Answer:
∠e = 105° because ∠e and the 105° angle are vertically opposite angles
∠h = 75° because ∠h and the 105° angle are supplementary angles
∠f = ∠h = 75° because ∠f and ∠h are vertically opposite angles
∠c = 105° because ∠c and the 105° are corresponding angles
∠b = 75° because ∠b and ∠f are corresponding angles
∠a = 105° because ∠a and ∠e are corresponding angles
∠d = 75° because ∠d and ∠h are corresponding angles
Step-by-step explanation:
The given diagram includes two parallel lines having a common transversal that crosses both (parallel) lines
By sing angle properties, we have;
∠e = 105° because ∠e and the 105° angle are vertically opposite angles formed by the same two straight lines and are therefore always equal
∠h = 180° - 105° = 75° because ∠h and the 105° angle are angles that form a straight line and are therefore supplementary angles which are angles that sum up to 180°. Therefore, ∠h + 105° = 180°, therefore ∠h = 75°
∠f = ∠h = 75° because ∠f and ∠h are vertically opposite angles
∠c = 105° because ∠c and the 105° are corresponding angles and corresponding angles are equal
Similarly, we have;
∠b = ∠f = 75° because ∠b and ∠f are corresponding angles
∠a = ∠e = 105° because ∠a and ∠e are corresponding angles
∠d = ∠h = 75° because ∠d and ∠h are corresponding angles

a) Find the maximum value of f(x,y) = x^{3}y^{4} for x,y \geq 0 on the unit circle.
Answers
The maximum value of f(x,y) on the unit of circle is [tex]\frac{48 \sqrt{21}}{2,401}[/tex].
The full question is in the attachment. From the unit circle
x² + y² = 1y² = 1 - x²Substitute to f(x,y)
f(x,y) = x³y⁴ = x³ (y²)² = x³ (1 - x²)²
f(x,y) = x³ (1 - 2x² + x⁴)
f(x,y) = x³ - 2x⁵ + x⁷
df/dx = 3x² - (2 × 5)x⁴ + 7x⁶
df/dx = 3x² - 10x⁴ + 7x⁶
df/dx = x² (3 - 10x² + 7x⁴)
To find the maximum or minimum value, the derivated equals zero.
0 = x² (7x⁴ - 10x² + 3)
0 = x² (x - 1) (x + 1) (7x² - 3)
x² = 0x = 0
f(x,y) = x³ - 2x⁵ + x⁷ = 0³ - (2 × 0⁵) + 0⁷ = 0x - 1 = 0
x = 1
f(x,y) = 1³ - (2 × 1⁵) + 1⁷ = 1 - 2 + 1 = 0x + 1 = 0
x = - 1
f(x,y) = (- 1)³ - (2 × (- 1)⁵) + (- 1)⁷ = - 1 + 2 - 1 = 0

keegan bought 5 T-shirts and 2 pairs of shoets for $49.50. Each pair of shorts, s, cost twice as much as each T-shirt, t.
Part A
Which system ot equations can vevused to find the price of the shorts and t-shirts?
(use attachment)
Part B
how much did keegan pay for each t-shirt and each pair of shorts?
Answers
Answer:
A) [tex]{2s + 5t = 49.50\\\\s = 2t[/tex]
B) Keegan paid $5.50 for each t-shirt and $11 for each short.
Step-by-step explanation:
A)
⭐ What is a system of equations?
A system of equations is two or more equations that intersect at a common point (x,y)We are asked to create a system of equations for Keegan's situation.
Let s = the price for every short
Let t = the price for every t-shirt
So, if Keegan buys 2 shorts and 5 t-shirts, his cost will be $49.50.
As an equation, this situation would be:
[tex]2s + 5t = 49.50[/tex]
It's given that the cost of 1 short is twice the cost of 1 t-shirt.
As an equation, this situation would be:
[tex]s = 2t[/tex]
B)
⭐How can we solve a system of equations?
You can solve a system of equations by substitutionYou can solve a system of equations by graphingYou can solve a system of equations by eliminationFor this problem, the best way to solve this system of equations is through substitution. I will demonstrate how to use substitution for this problem.
Using the equations [tex]2s + 5t = 49.50[/tex] and [tex]s = 2t[/tex], we will literally substitute a variable from one equation into another equation to solve for the other variable.
Given that [tex]s = 2t[/tex]:
[tex]2s + 5t = 49.50[/tex]
[tex]2(2t) + 5t = 49.50[/tex]
[tex]4t + 5t = 49.50[/tex]
[tex]9t = 49.50[/tex]
[tex]t = 5.50[/tex]
∴ It costs Keegan $5.50 for one t-shirt.
Now, we can substitute the value of t into the same equation to solve for the value of s.
Given that [tex]t = 5.50[/tex]:
[tex]2s + 5(5.50) = 49.50[/tex]
[tex]2s + 27.5 = 49.50[/tex]
[tex]2s = 22[/tex]
[tex]s = 11[/tex]
∴ It costs Keegan $11 for one short.

What is time and work?Time and work are concerned with the amount of time it takes a person or a group of people to complete a task and the effectiveness of the work performed by each of them. The fundamental idea behind Time and Work is comparable to the idea behind Proportionality, which is present in all arithmetic disciplines.
"How much work one person can complete in one day is what the term "work efficiency" refers to. For instance, someone can complete a task in two days. In other words, he may complete 50% of the work in a single day. His effectiveness will therefore be 50%.
Given that,

What is the inverse of 7 mod 11?
Answers
The inverse of 7 modulo 11 is 4, which means that 4 multiplied by 7 gives a number congruent to 1 (mod 11). This means that 4 is the number that when multiplied by 7 gives a remainder of 1 when divided by 11.
In modular arithmetic, the inverse of a number is the number that when multiplied by the original number gives a result that is congruent to 1 (modulus). For example, if we take the modulus of 11 as an example, then the inverse of 7 modulo 11 is 4, since 7*4 = 28 ≡ 1 (mod 11). This means that 4 is the number that when multiplied by 7 gives a remainder of 1 when divided by 11. The inverse of a number modulo a given modulus can be calculated using the Extended Euclidean algorithm. This algorithm allows us to find the inverse of a number modulo a given modulus by solving a series of equations and using the result to calculate the inverse. For example, in the case of 7 mod 11, the Extended Euclidean algorithm gives us the result 4, which is the inverse of 7 mod 11.
11 = 7*1 + 4
7 = 4*1 + 3
4 = 3*1 + 1
3 = 1*3 + 0
By reading the equations from right to left, we can see that the inverse of 7 mod 11 is 4, since 4*7 = 28 ≡ 1 (mod 11).

The mode of a set of numbers is the value that occurs most frequently in the set. In the set {1, 1, 2, 2, 3, 3, 4, 4}, the value that occurs most frequently is 1, 2, 3, and 4, so the mode of this set is 1, 2, 3, and 4.
It's important to note that a set of numbers can have more than one mode if multiple values occur with the highest frequency. A set of numbers that has multiple modes is called a multimodal set. In the example set {1, 1, 2, 2, 3, 3, 4, 4}, all four values occur with the same frequency, so the set is multimodal.
On the other hand, if no value occurs more frequently than any other value, the set is said to have no mode. For example, the set {1, 2, 3, 4, 5} has no mode because all values occur with the same frequency.

The linen fabric costs $13.12 per yard, the satin fabric costs $9.99 per yard, and the faux fur costs $14.99 per yard. She also needs to buy the pillow inserts, which are $9.99 each. What is the total cost Kelly spends on the materials for the pillows?
Answers
Answer:
The total cost of the materials for the pillows is $172.37
Step-by-step explanation:
First, we need to calculate how many yards of each type of fabric Kelly needs to buy. She needs 2 linen pillows, which means she needs 22 = 4 yards of linen fabric.
She also needs 2 satin pillows, which means she needs 22 = 4 yards of satin fabric.
She also needs 1 faux fur pillow, which means she needs 12 = 2 yards of faux fur fabric.
The total cost of the linen fabric is 4*$13.12 = $52.48.
The total cost of the satin fabric is 4*$9.99 = $39.96.
The total cost of the faux fur fabric is 2*$14.99 = $29.98.
The total cost of the materials for the pillows is $52.48 + $39.96 + $29.98 = $122.42.
Finally, Kelly needs to buy 5 pillow inserts at $9.99 each, which means she needs to spend 5*$9.99 = $49.95 on pillow inserts.
The total cost of the materials for the pillows is $122.42 + $49.95 = $172.37.

What is the end behavior of the graph of the polynomial function y 10x9 4x?
Answers
The end behavior of the graph of the polynomial function y = 10x^9 + 4x is asymptotic to negative infinity as x approaches negative infinity, and asymptotic to positive infinity as x approaches positive infinity.
The end behavior of a polynomial function is determined by the degree of the polynomial. The polynomial function y = 10x^9 + 4x is a degree 9 polynomial, so it will exhibit an asymptotic behavior in which the graph approaches either positive or negative infinity as x approaches either positive or negative infinity. In this case, the graph will approach negative infinity as x approaches negative infinity, and it will approach positive infinity as x approaches positive infinity. This behavior is due to the fact that the highest degree term (10x^9) will dominate the behavior of the graph as x gets very large in either the positive or negative direction. The lower degree terms (4x) will have a smaller effect on the end behavior of the graph.

What is the median of 5 and 7?
Answers
The median of 5 and 7 is 6.
The median is the middle point in a dataset—half of the data points are smaller than the median and half of the data points are larger.
A data set's median value is the point where 50% of the data points have values that are lower or equal to it, and 50% of the data points have values that are higher or equal to it.
To arrange the data points in ascending order for a small data set, count the number of data points (n).
To get the rank of the data point whose value is the median when the number of data points is unequal, multiply the total by 1 and divide the results by 2.
Median = (5+7)/2 = 12/2 = 6
Thus, the median of 5 and 7 is 6.

Is a discontinuity the same as a hole?
Answers
A discontinuity is a point at which a function is not continuous. This means that there is a break or gap in the function at that point, which can be caused by a variety of factors such as a sudden change in the value of the function, a division by zero, or an undefined value.
A function can have a "hole" if it is not defined at a certain input value. For example, consider the following function:
f(x) = 1/x
This function has a hole at x=0 because it is not defined at that value. If you try to evaluate the function at x=0, you will get an error or an undefined result.
A hole is a missing or incomplete part of a function. For example, a function may have a hole at a certain point if the function is not defined at that point, or if there is a gap in the graph of the function at that point.
So, while a discontinuity is a break or gap in a function, a hole is a missing or incomplete part of the function. These two concepts are related, but they are not the same thing.
To determine whether a function has a hole, you can consider the domain of the function, which is the set of all input values for which the function is defined. If there are any values in the domain for which the function is not defined, then the function has a hole at those values.

f(x) = 1/x
Because it is not defined at x=0, this function has a gap there. You will encounter an error or an undefined outcome if you attempt to evaluate the function at x=0.
A hole is a component of a function that is absent or inadequate. For instance, if a function is not defined at a particular point or if there is a gap in the function's graph at that location, the function may have a hole there.
Therefore, a hole is a missing or unfinished portion of the function, whereas a discontinuity is a break or gap in the function. Although these two ideas are distinct from one another, they are linked.

Answer:
x >= 1/3
Step-by-step explanation:
y = (e^x + 1)/3
x = (e^y + 1)/3 ==> inverse function is when you switch x and y
3*x = 3 * (e^y + 1)/3 ==> solve for y by first multiplying both sides by 3
3x = e^y + 1
3x - 1 = e^y + 1 - 1
3x - 1 = e^y ==> now take natural log on each side to isolate y
ln(3x - 1) = ln(e^y)
y = ln(3x - 1) ==> simplify
[tex]f^{-1}[/tex](x) = ln(3x - 1) ==> plug in [tex]f^{-1}[/tex](x) for y to indicate the inverse function
3x - 1 >= 0 ==> you can't have the log function of a negative number
3x - 1 + 1 >= 0 + 1 ==> add 1 on both sides to isolate x
3x >= 1
3x/3 >= 1/3
x >= 1/3
in the xy plane, the circles with equations (x-3) + y = 11 and (x+2) + y = r are externally tangent what is the value or r ?
let me know if you know man
Answers
In the XY plane, the circles with equations (x-3) + y = 11 and (x+2) + y = r are externally tangent. the value of r is -6.
What is tangent?Generally, To find the value of r, we can start by solving for the centers and radii of the two circles.
The equation of the first circle is of the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius. We can rewrite the equation of the first circle as (x - 3)² + y² = 11², so the center of the circle is (3, 0) and the radius is 11.
The equation of the second circle is also of the form (x - h)₂ + (y - k)₂ = r². We can rewrite the equation of the second circle as (x + 2)² + y² = r², so the center of the circle is (-2, 0) and the radius is r.
Since the two circles are externally tangent, the distance between their centers is equal to the sum of their radii. Therefore, the distance between the centers is equal to 11 + r. We can use the distance formula to find the distance between the centers:
distance = √((h₂ - h₁)^2 + (k₂ - k₁)²)
Plugging in the coordinates of the centers, we get:
distance = √((-2 - 3)^2 + (0 - 0)^2) = √(5^2 + 0^2) = √(25) = 5
Since the distance between the centers is equal to the sum of the radii, we can set up the equation:
5 = 11 + r
Solving for r, we get:
r = 5 - 11 = -6
Therefore, the value of r is -6.

The base of the cone has a radius of 4.5 inches. The height of the cone is 16 inches.
If the cone shown above is sliced by a plane that passes through the center of the base, and also passes through the top vertex, what is the area of the cross-section of the cone?
Answers
According to the given statement the area of the cross section of the cone is 72 square units.
What does the word cone actually mean?a solid produced by rotating one of the legs of a right triangle. A solid that is surrounded by a circle and other closed planar base and indeed the surface created by line segments connecting each point here on base's perimeter to a single vertex is known as a right circle cone; for more information, see the Density Formulas Table.
Briefing:From the given information the height is 16 inches and the radius is 4.5 inches becuase the cone is sliced by a plane that passes through the center of the base, and also passes through the top vertex
So, The radius would be half the base, so the base would be 4.5 * 2 = 9 inches.
The area of the cross section of the cone is found by multiplying the base by the height, then dividing by two.
Area of the cross section of the cone = (9 x 16)/2 = 144
144 / 2 = 72 square inches.
