Answer:
£5.95
Step-by-step explanation:
To find the cost of 12 DVDs, let x = 12
C(12) = 0.35 x 12 + 1.75
C(12) = 4.2 + 1.75
C(12) = 5.95
The cost of manufacturing 12 DVDs is $5.95.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, the cost of manufacturing a single DVD is represented by C(x) = 0.35x+ 1.75.
When, x=12
C(12)=0.35×12+1.75
C(12)=5.95
Therefore, the cost of manufacturing 12 DVDs is $5.95.

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x
f(x) = [tex]\frac{2}{x}[/tex] and g(x) = [tex]\frac{2}{x}[/tex]
Step-by-step explanation:
given f(x) = 2/x and g(x) = 2/x
f(g(x)) = 2/(g(x)) = 2/2/x = x/2 × 2 = x
g(f(x)) = 2/(f(x)) = 2/2/x = x/2 × 2 = x
therefore they are inverses
since f(g(x)) = g(f(x)) = x.

QUESTION 1: Marques made a mistake when solving this problem. On what line did he make the error?
Line 1 Line 2 Line 3 Line 4 Line 5
Line 2 presents the error for the solution presented because the square of numbers: 14 and 8 was calculated incorrectly.
Law CosinesThis law can be applied when two sides of the triangle and the angle formed for these sides are known. Therefore, from the law of cosines, it is possible to write the relation between sides and their respective cosines. See below:
[tex]c^2=a^2+b^2-2*a*b*cos(C)[/tex]
For solving this question, you should apply the Law Cosines and after that compare your solution with this exercise. From the comparison, you should identify the mistake for the solution presented in this problem.
Applying Law Cosines[tex]c^2=a^2+b^2-2*a*b*cos(C)\\ \\ c^2=14^2+8^2-2*14*8*cos(80)\\ \\ c^2=196+64-224*0.1736\\ \\ c^2=196+64-38.8864\\ \\ c^2=221.1136\\ \\ c=\sqrt{221.1136}=14.9[/tex]

Answer:
The rate of change, slope, m is
m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so
m=(39-5)/(21-4)
m=34/17

Jenny has a 12-sided die.
If Jenny rolls the die 180 times, how many times can Jenny predict she will roll a 12?
The prediction of a roll of 12 is the expected value of rolling a 12
Jenny can predict 15 as the number of times she will roll a 12
How to predict the number of rolls of 12?The dice is a 12-sided dice.
This means that the dice has 12 sides.
So, the probability of obtaining a 12 is:
P(12) = 1/12
In a roll of 180 times, the number of times a 12 is expected to show is:
E(x) = np
This gives
E(x) = 180 * 1/12
Evaluate the product
E(x) = 15
Hence, Jenny can predict 15 as the number of times she will roll a 12

Solve for x.
Answer and Step-by-step explanation:
To solve for x, we need to look at 2 deciding factors that allows us to be able to find x.
We are given 2 parallel lines, denoted by the arrow pointing right on the end of both of them, and a transversal line that cuts through the two lines. Because the lines are parallel, the angles that are formed by the transversal like will be equal or correspondent to each other in a few ways.
For the angles we are given, the angles are on the same side of the transversal line, and on the top of their respective parallel lines. Because of this, the angles are equal to each other.
To solve, set the two angles equal to each other.
4x + 20 = 2x + 60
Subtract the 2x from both sides of the equation.
2x + 20 = 60
Subtract the 20 from both sides of the equation.
2x = 40
Divide both sides by 2.
x = 20
x is equal to 20.

Given -
two parallel lines with a transversal.
To find -
to find the value for x.
Concept applied -
Here in the figure, these two angles let's say 1 = 4x + 20° and 2 = 2x + 60° are corresponding angles. And we know that corresponding angles are equal. As all these angles that have the same position in leu the parallel lines and the transversal are corresponding pairs. Therefore, 1 = 2
Solution -
➙ 4x + 20° = 2x + 60°
➙ 4x - 2x = 60° - 20°
➙ 2x = 40°
➙ x = 40°/2
➙ x = 20°
Henceforth, the value of x = 20°.
