What is a Linear Function?A linear function is defined as a function in the form of f(x) = mx + c where 'm' and 'c' are real numbers.
We have been given that relationship A has a greater rate than relationship B.
Hours Worked Amount Paid
2 30.4
4 60.8
5 76
8 121.60
Let the number of hours worked x and the total amount paid y.
As per the given functions
⇒ y = 15.4x ...(i)
⇒ y = 15.2x ...(ii)
⇒ y = 16.4x ...(iii)
⇒ y = 14.9x ...(iv)
As per the linear function (ii),
⇒ y = 15.2×2
⇒ y = 30.4
The above is satisfy the point, therefore, it represents relationship A
Hence, the required equation is y = 15.2x which could represent relationship A.

Answers
A = tan^(-1) 2.1445 = 64.999 ≈ 65°
In a right triangle:
A + B = 90°
65° + B = 90°
B = 90° - 65° = 25°
Answer:
A ) 25° (or your first option)
The requried measure of angle B is 25 degrees. Option A is correct.
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
Here,
In a right triangle, the tangent of an acute angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
Let A be one of the acute angles of the right triangle. Then, we have:
tan(A) = opposite/adjacent
Given that the tangent of angle A is 2.1445, we can write:
2.1445 = opposite/adjacent
Since angle B is also an acute angle of the same right triangle, we have:
tan(B) = opposite/adjacent
But since the sum of the angles of any triangle is 180 degrees, and one of the angles in this triangle is a right angle (90 degrees), we have:
A + B + 90 = 180
B = 90 - A
Substituting the expression for B into the equation for the tangent of angle B, we get:
tan(90 - A) = opposite/adjacent
tan(90 - A) = (1/tan(A)) x adjacent/opposite
tan(90 - A) = (1/2.1445) x adjacent/opposite
tan(90 - A) = 0.466
Taking the inverse tangent of both sides, we get:
90 - A = tan⁻¹0.466)
90 - A = 25.38
A = 90 - 25.38
A = 64.62
Therefore, the measure of angle B is,
B = 90 - A
= 90 - 64.62 = 25.38 degrees
Thus, the requried measure of angle B is 25 degrees.

Solve the proportion. 2/8 = -30/x
Answers
[tex]\frac{2}{8} = -\frac{30}{x} [/tex]
Now cross multiply the -30 and the 8 so -30 x 8 = -240
Now take the -240 and divide it by 2
[tex] \frac{-240}{2} = -120[/tex]
So x = -120
Answer = 120
The solution to the proportion 2/8 = -30/x is x = -120, found by cross multiplying and simplifying the resulting equation.
To solve the proportion 2/8 = -30/x, we will cross multiply to find the value of x. After cross multiplying, we obtain 2x = -30 imes 8. Simplifying this gives us 2x = -240, and dividing both sides by 2 yields x = -120. So the solution to the proportion is x = -120.

Find the value of x or y so that the line through the points has the given slope of (x, -8) and (-7,5); slope: -13/7
Answers
The required value of x is 112/13 which line through the points has the given slope of (x, -8) and (-7,5).
What is the slope of the line?The slope of the line is defined as the gradient of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
We have been given two points :(x, -8) and (-7,5)
As per the line of slope,
m = (y₂ - y₁)/(x₂ -x₁ )
Here
x₁ = x, y₁ = 8
x₂ = -7, y₂ = 5
Substitute values in the above formula
-13/7 = (5 - 8)/(-7 - x )
-13/7 = -3/(-7 - x )
-13(-7 - x ) = -21
91 + 13x = -21
13x = -21 - 91
13x = 112
x = 112/13
Therefore, the required value of x is 112/13.

Find the limit of the function algebraically. limit as x approaches zero of quantity negative six plus x divided by x to the fourth power.
Answers
The limit as x approaches zero of the function (-6 + x)/x^4 is 0. This is arrived at using L'Hopital's Rule, which instructs us to take the limits of the derivatives of the numerator and denominator when the initial function limit causes an indeterminate form (0/0, infinity/infinity).
Explanation:The limit of the function negative six plus x divided by x to the fourth power as x approaches zero cannot be solved using traditional limit computations as it creates indeterminate form. However, the L'Hôpital's rule
Rule can be used to determine this limit.
Under L'Hôpital's rule
rule, to solve for the limit of a function that results in an indeterminate form 0/0 or infinity/infinity, you take the derivative of the numerator and the derivative of the denominator independently, and then find the limit of that quotient as x approaches the given value.
In this case, the function is (-6+x)/x4. The derivative of -6+x is 1 and the derivative of x4 is 4x3. Therefore, after the first iteration of L'Hopital's rule, you are finding the limit as x approaches zero of 1/(4x3). Running the rule again we get 0/(12x2). Clearly there, the numerator is 0 and since x2 will be a non-negative number the limit would be 0. Hence, the limit of the function as x approaches zero is 0.

Volume occupied each small cube = v = [tex]a^3=(1 inch )^3= 1 inches^3[/tex]
Length of the big cube = A
Volume of the big cube = V
[tex]V=A^3[/tex]
He uses 64 cubes with side lengths of 1 inch to completely fill the container.
[tex]V=64\times v=64\times 1 inches^3[/tex]
