This is because the set notation {x|x>4} U {x|x<-2} represents the union of all values of x that are greater than 4 and all values of x that are less than -2. The graph shows all the values of x that are greater than 4 and all values of x that are less than -2. The graph also includes the values of x between -3 and 5, it encompasses all the values that are greater than 4 and all values that are less than -2.
The graph represents the solution to the following sentence is (C).
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have,
{x | x >4 } ∪ {x | x < -2}
Here the set notation {x|x>4} U {x|x<-2} represents the union of all values of x that are greater than 4 and all values of x that are less than -2.
The graph displays all instances of x larger than 4 and all instances of x less than -2.
The graph covers all x values higher than or equal to 4, as well as all x values less than or equal to -2.
It also includes x values between -3 and 5.
Thus, the number line is C.

Franklin Lyons is married and claims 3 withholding allowances. He gets paid overtime if he works over 40 hours in a week. His gross pay is $958.38. Find the Federal Withholding Tax.
Based on the assumptions, the estimated Federal Withholding Tax for Franklin Lyons would be approximately $191.68.
Determine Franklin's taxable income:
To calculate the taxable income, we need to subtract any deductions or exemptions from his gross pay. We'll consider his gross pay as the taxable income.
Taxable Income = Gross Pay = $958.38
Estimate the Federal Withholding Tax rate:
The Federal Withholding Tax rate depends on the taxable income and the individual's filing status. Let's assume a general tax rate of 20% for this estimation.
Federal Withholding Tax rate = 20%
Calculate the Federal Withholding Tax:
To find the withholding tax, multiply the taxable income by the tax rate:
Federal Withholding Tax = Taxable Income * Federal Withholding Tax rate
= $958.38 * 0.20
= $191.68
Thus, the answer is $191.68.

Graph this line using the slope and y-intercept:
y = 4x - 10
Answer:
-10
Step-by-step explanation:
The required y-intercept of the line y = 4x - 10 is -10.
What is the intercept in the equation?
In the equation, the intercept is the value of the linear function where either of the variables is zero.
Here,
The equation y = 4x - 10 is in slope-intercept form, where the coefficient of x is the slope of the line, and the constant term is the y-intercept.
So, the y-intercept of the line y = 4x - 10 is -10. This means that the line intersects the y-axis at the point (0,-10). When x is 0, the value of y is -10, which is the y-intercept.
Thus, the required y-intercept of the line y = 4x - 10 is -10.

A graph of the image of polygon DGF after a dilation centered at the origin with a scale factor of 1.5 is shown below.
What is a dilation?In Geometry, a dilation is a type of transformation which typically changes the dimension (size) or side lengths of a geometric figure, but not its shape.
This ultimately implies that, the side lengths of the dilated geometric figure would be enlarged or reduced based on the scale factor applied.
In this scenario an exercise, we would dilate the coordinates of the polygon by applying a scale factor of 1.5 that is centered at the origin as follows:
D (-2, 0) → (-2 × 1.5, 0 × 1.5) = D' (-3, 0).
G (0, 2) → (0 × 1.5, 2 × 1.5) = G' (0, 3).
F (2, -2) → (2 × 1.5, -2 × 1.5) = F' (3, -3).

From the given graph we can see that,
The curve represent cubic function
And we know that such cubic function is of the form
f(x) = y = -(ax³ + bx² + cx + d)
Since,
A function can approach two separate limits: one in which the variable approaches its limit by using values more than the limit, and one in which the variable approaches its limit by using values less than the limit.
Case 1:
Take limit of x approaching to infinity,
[tex]\lim_{n \to \infty} f(x) = y = -\infty[/tex]
Hence,
As x approaches to infinity the
y approaches to negative infinity.
Case 2:
Take limit of x approaching to negative of infinity,
Now since degree of function is 3 which is odd
Therefore,

A restaurant makes smoothies in batches of 12.5 litres.
The smoothies are made from ice cream and a mixed fruit
juice in the ratio 3 : 2.
34% of the juice is apple juice.
Work out the maximum number of batches of smoothie that
can be made from 51 litres of apple juice.
Answer: If 34% of the mixed fruit juice is apple juice, then 66% of it is a combination of other fruit juices. We can assume that the ratio of apple juice to other fruit juices remains the same in the ice cream and mixed fruit juice mixture.
Let the volume of ice cream in each batch be 3x litres and the volume of mixed fruit juice be 2x litres. Then the total volume of mixture in each batch is 5x litres.
If 34% of the mixed fruit juice is apple juice, then the volume of apple juice in each batch is 0.34 × 2x = 0.68x litres. The volume of other fruit juices in each batch is 2x − 0.68x = 1.32x litres.
The ratio of ice cream to mixed fruit juice is 3 : 2, so we have:
3x : 2x = ice cream : mixed fruit juice
Simplifying, we get:
ice cream = 1.5 × mixed fruit juice
Substituting the values we obtained earlier, we have:
3x = 1.5 × 2x
x = 0.75
Therefore, the volume of ice cream in each batch is 3x = 2.25 litres, and the volume of mixed fruit juice is 2x = 1.5 litres.
To make 1.5 litres of mixed fruit juice, we need 0.68 litres of apple juice and 0.82 litres of other fruit juices.
To make 12.5 litres of smoothies, we need 2.25 litres of ice cream and 10.25 litres of mixed fruit juice. Of this, 0.68 litres is apple juice and 9.57 litres is other fruit juices.
Therefore, to make 12.5 litres of smoothies, we need 0.68/1.5 × 12.5 = 5.67 litres of apple juice.
To make 51 litres of apple juice, we can make a maximum of 51/5.67 ≈ 9 batches of smoothies.

These atomic formulas represent basic assertions or relationships between elements or sets.
In logic and mathematical logic, "atomic formulas" refer to the simplest, indivisible formulas that do not contain any logical connectives or quantifiers.
They are the building blocks from which more complex formulas are constructed.
In set theory, the atomic formulas are typically statements about membership or equality.
For example, "x belongs to y" (x ∈ y) and "x equals y" (x = y) are atomic formulas in set theory.
Using logical connectives (such as conjunction, disjunction, negation, implication, and equivalence) and quantifiers (such as "for all" (∀) and "there exists" (∃)), we can combine atomic formulas to form more complex formulas, enabling us to express a wide range of logical statements and mathematical properties.

Answer:
3) A = 35.2°, B = 38.6°, C = 106.2°
4) B = 70.4°, C = 31.6°, a = 18.7
Step-by-step explanation:
Question 3To solve for the remaining angles of the triangle ABC given its side lengths, use the Law of Cosines for finding angles.

Given sides of triangle ABC:
a = 12b = 13c = 20Substitute the values of a, b and c into the Law of Cosines formula and solve for angle C:
[tex]\implies \cos(C)=\dfrac{a^2+b^2-c^2}{2ab}[/tex]
[tex]\implies \cos(C)=\dfrac{12^2+13^2-20^2}{2(12)(13)}[/tex]
[tex]\implies \cos(C)=\dfrac{-87}{312}[/tex]
[tex]\implies \cos(C)=-\dfrac{29}{104}[/tex]
[tex]\implies C=\cos^{-1}\left(-\dfrac{29}{104}\right)[/tex]
[tex]\implies C=106.191351...^{\circ}[/tex]
To find the measure of angle B, swap b and c in the formula, and change C for B:
[tex]\implies \cos(B)=\dfrac{a^2+c^2-b^2}{2ac}[/tex]
[tex]\implies \cos(B)=\dfrac{12^2+20^2-13^2}{2(12)(20)}[/tex]
[tex]\implies \cos(B)=\dfrac{375}{480}[/tex]
[tex]\implies B=\cos^{-1}\left(\dfrac{375}{480}\right)[/tex]
[tex]\implies B=38.6248438...^{\circ}[/tex]
To find the measure of angle A, swap a and c in the formula, and change C for A:
[tex]\implies \cos(A)=\dfrac{c^2+b^2-a^2}{2cb}[/tex]
[tex]\implies \cos(A)=\dfrac{20^2+13^2-12^2}{2(20)(13)}[/tex]
[tex]\implies \cos(A)=\dfrac{425}{520}[/tex]
[tex]\implies A=\cos^{-1}\left(\dfrac{425}{520}\right)[/tex]
[tex]\implies A=35.1838154...^{\circ}[/tex]
Therefore, the measures of the angles of triangle ABC with sides a = 12, b = 13 and c = 20 are:
A = 35.2°B = 38.6°C = 106.2°[tex]\hrulefill[/tex]
Question 4Given values of triangle ABC:
A = 78°b = 18c = 10First, find the measure of side a using the Law of Cosines for finding sides.
[tex]\boxed{\begin{minipage}{6 cm}\underline{Law of Cosines (for finding sides)} \\\\$c^2=a^2+b^2-2ab \cos (C)$\\\\where:\\ \phantom{ww}$\bullet$ $a, b$ and $c$ are the sides.\\ \phantom{ww}$\bullet$ $C$ is the angle opposite side $c$. \\\end{minipage}}[/tex]
As the given angle is A, change C for A in the formula and swap a and c:
[tex]\implies a^2=c^2+b^2-2cb \cos (A)[/tex]
Substitute the given values and solve for a:
[tex]\implies a^2=10^2+18^2-2(10)(18) \cos (78^{\circ})[/tex]
[tex]\implies a^2=424-360\cos (78^{\circ})[/tex]
[tex]\implies a=\sqrt{424-360\cos (78^{\circ})}[/tex]
[tex]\implies a=18.6856038...[/tex]
Now we have the measures of all three sides of the triangle, we can use the Law of Cosines for finding angles to find the measures of angles B and C.
To find the measure of angle C, substitute the values of a, b and c into the formula:
[tex]\implies \cos(C)=\dfrac{a^2+b^2-c^2}{2ab}[/tex]
[tex]\implies \cos(C)=\dfrac{(18.6856038...)^2+18^2-10^2}{2(18.6856038...)(18)}[/tex]
[tex]\implies \cos(C)=0.852040063...[/tex]
[tex]\implies C=31.565743...^{\circ}[/tex]
To find the measure of angle B, swap b and c in the formula, and change C for B:
[tex]\implies \cos(B)=\dfrac{a^2+c^2-b^2}{2ac}[/tex]
[tex]\implies \cos(B)=\dfrac{(18.6856038...)^2+10^2-18^2}{2(18.6856038...)(10)}[/tex]

dy/dx = d/dx(3x^4) - d/dx(2x^2) + d/dx(5x) - d/dx(2)
Taking the derivative of each term:
dy/dx = 12x^3 - 4x + 5
Now, let's evaluate the derivative at the given points:
Point (0, -2):
Substituting x = 0 into the derivative:
dy/dx = 12(0)^3 - 4(0) + 5
dy/dx = 0 - 0 + 5
dy/dx = 5
Therefore, the gradient at (0, -2) is 5.
Point (1, 4):
Substituting x = 1 into the derivative:
dy/dx = 12(1)^3 - 4(1) + 5
dy/dx = 12 - 4 + 5
dy/dx = 13
Therefore, the gradient at (1, 4) is 13.
mara works for an electronics store and receives a 6.5% commission on her sales. She also recevies a weekly salary 460. mara's boss asks her to specialize in the sale of flat screen televisions that cost $414 each, which means those are the only items she will sell. write and sole an equation to find the number of televisions, t, she sells in one week if she earns 890.56 for the week
Answer:
16 tvs
Step-by-step explanation:
Maura's earnings for the week equal her weekly salary (460) plus she earns 6.5% commission x number of flat screens sold x $414.
So: Total Earnings = 460+ 0.065*414*t where t is the number of tvs she has sold.
If total earnings = 890.56, just substitute that above and solve for t.
890.56= 460+ 0.065*414*t
430.56=0.065*414*t
430.56=26.91*t
430.56/26.91 = t
16 = t
She sold 16 tvs to earn 890.56.
