Use the information below for Part A, Part B, and Part C.
f(x) = 1/2x -7
g(x) = 2x + 14
Part A: Find (fog)(x). Show your work.
Part B: Find (gºf)(x). Show your work.
Part C: Use your answers to Part A and Part B to determine whether the two functions are inverses. Explain your answer fully.
Answer:
(1/2(2x+14)-7) = 1x+7-7= x g(f(x))= 2(1/2x-7)+14= x-14+14= xWe have the result being two variables of linearity hence they are not inverses. In order to be inverses they should have had switched notations, ie: -x vs x9514 1404 393
Answer:
A: (f∘g)(x) = x
B: (g∘f)(x) = x
C: the functions are inverses
Step-by-step explanation:
A: (f∘g)(x) = f(g(x)) = f(2x +14)
= 1/2(2x +14) -7 = x +7 -7 = x
(f∘g)(x) = x
__
B: (g∘f)(x) = g(f(x)) = g(1/2x -7)
= 2(1/2x -7) +14 = x -14 +14 = x
(g∘f)(x) = x
__
C: When a function is operated on by its inverse, then original argument value is restored. That is the case for functions f and g, so the two functions are inverses.

A bag contains 7 milk and 5 dark chocolates. A sweet is selected at random. What is the probability of choosing: P(milk) = P(not milk) =
Answer: P(7)=P(5)=12
Step-by-step explanation:
The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
A sack contains 7 milk and 5 dim chocolates. A sweet is chosen indiscriminately.
The total number of the sweets will be given as,
Total events = 7 + 5 = 12
The probability of choosing milk will be given as,
P = (7/12)
P = 0.5833
The probability of choosing not to milk will be given as,
P = (5/12)
P = 0.4167
The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.

Which expression is equivalent to -4x - 36?
A. 4(x - 9)
B. 2(2x - 18)
C. -2(2x - 18)
D. -4(x + 9)
D. -4(x+9)
For this you distribute the number outside the parentheses to both numbers inside.
A. 4(x-9)=
4x-36
B. 2(2x-18)=
4x-36
C. -2(2x-18)=
-4x+36
D. -4(x+9)=

Therefore, D is the answer
Evaluate: ab when a = 2 and b=4
Answer:
8
Step-by-step explanation:
ab = 2 * 4 = 8
Answer:
8
Step-by-step explanation:
ab when a = 2 and b = 4
First, plug in the values into the expression.
ab = (a)(b)
(2)(4)
When two numbers are set next to each other in parentheses, you are multiplying them.
2 × 4 = 8
Therefore, ab = 8

Nigel and Mia are searching for a treasure chest under water. The straight line distance between them is 100 meters.
A triangle has points Nigel, Mia, and Treasure Chest. The distance from Nigel to Mia is 100 meters. The angle between Treasure Chest, Nigel, and Mia is 65 degrees. The angle between Nigel, Mia, and Treasure Chest is 80 degrees.
Given the angles in the diagram, who is closer to the treasure chest and why?
Nigel is closer because his distance to the chest is opposite the larger angle.
Mia is closer because her distance to the chest is opposite the smaller angle.
Nigel is closer because his distance from the chest is 100 meters.
Mia is closer because her distance from the chest is 100 meters.
Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees.
What is triangle?A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.
Given is a triangle that has points Nigel, Mia, and Treasure Chest. The distance from Nigel to Mia is 100 meters. The angle between Treasure Chest, Nigel, and Mia is 65 degrees. The angle between Nigel, Mia, and Treasure Chest is 80 degrees.
Refer to the image attached.
It can be seen that Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees. We can conclude this from the fact that the longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle
Therefore, Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees.

Use the Law of Cosines to write an expression equivalent to a. I need this answer urgently pls!
9514 1404 393
Answer:
a = √(b² +c² -2bc·cos(A))
a = √(c² -b²)
Step-by-step explanation:
For sides a, b, c, and opposite angles A, B, C, the general form of the law of cosines is ...
a² = b² + c² -2bc·cos(A)
An expression for 'a' can be written by taking the square root.
a = √(b² +c² -2bc·cos(A))
__
If you recognize that cos(A) = b/c, then a substitution can be made:
a = √(b² +c² -2(bc)(b/c)) = √(b² +c² -2b²)
a = √(c² -b²) . . . . . . . same as the Pythagorean theorem

Answer:
V = 49 m³
Step-by-step explanation:
Volume in November 2015 = 6287 m³
Volume in August 2015 = 6238 m³
We need to find the volume of water used between August and November. It can be calculated as follows :
V = 6287 m³ - 6238 m³
= 49 m³
So, the required volume is 49 m³.
express x^2 - 8x + 5 in the form (x - a)^2 - b where a and b are integers
Answer:
x^2 -8x + 5 = (x-4)^2 - 11
Step-by-step explanation:
Here we want to write the given expression in the form
x^2-8x + 5 can be written as follows;
(x-4)^2 = x^2 - 8x + 16
All we have to do is to subtract 11
Thus, we have it that;
x^2-8x + 5 = (x-4)^2 - 11
HELP In △ABC, m∠A = 75° and m∠C = 20°, What is m∠B?
To solve this question, we must know the the angle sum property of a triangle. Therefore the value of ∠B is 85° when ∠A = 75° and ∠C=20° in △ABC
What is angle sum property of a triangle?According to angle sum property of a triangle, the sum of all angles of a triangle is always 180 degree. It can never be more than or less than 180 degree. If two angles of a triangle is given then the third angle can be calculated by subtracting the sum of two angle from 180°
The sum of the three angles in a triangle = 180° , that is
∠ A + ∠ B + ∠ C = 180°
Substituting the given values in the given equation we get
75° + ∠ B + 20° = 180°
∠ B + 95° = 180°
subtracting 95° from both sides we get
∠ B = 85°
Therefore the value of ∠B is 85° when ∠A = 75° and ∠C=20° in △ABC
