f(x) = x2 – x + 11
g(x) = -x – 4
Find: (gof)(x)
Answer:
g(f(x)) = -x^2 + x - 15
Step-by-step explanation:
g(f(x^2 - x + 11) = -1 * (x^2 - x + 11) - 4 = -x^2 + x - 11 - 4 = -x^2 + x - 15
what is opportunity sampling
Answer:
Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.
This ultimately implies that, an opportunity sampling is a non-probability sampling in which a researcher select participants based on their availability for the study.
For example, John a psychologist standing on the street requesting that passersby join in his research study.

Write the equation 3x+2y=8 in general form. SHOW YOUR WORK PLEASE
Answer:
3x+2y-8=0
Step-by-step explanation:
The equation 3x+2y=8 in general form is 3x + 2y - 8 = 0 respectively.
What is a numerical expression?A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
We are given that the equation 3x+2y=8.
The equation of straight line is written as y = mx + c
3x+2y=8.
2y = 8 - 3x
y = 8/2 - 3/2x
y = 4 - 3x/2
Hence, the general form is 3x + 2y - 8 = 0.

Here is another question. It wants me to solve it
Answer:
[tex]x>-11[/tex]
Step-by-step explanation:
[tex]10+2x>-12[/tex]
Subtract both sides by 10
[tex]10+2x-10>-12-10\\2x>-22[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}>\frac{-22}{2} \\x>-11[/tex]

a metal pipe is 77 cm long the inner diameter of the cross section is 4 cm and the outer diameter is 4.8 cm find the (i) inner curved surface area (ii) outer curved surface area (iii) total surface area
Answer with full step by step explaination
Answer:
Step-by-step explanation:
outer area=
first need to find the circumference of outer diameter
= π×4.8
= 15.079644.... cm
to find the outer curved area you would then do
= 77×15.079644
(ii) =1161.13264 cm²
inner curve area
circumference= π×4
=12.5663706.... cm
77×12.5663706
(i) =967.610537 cm²
total surface area=
as the outer and inner curved areas are already found only the top and bottom surfaces need to be
= area of larger circle
=π×4.8²
=72.382294.... cm²
smaller circle
=π×4²
=50.2654824.... cm²
72.382...-50.265
=22.1168116 x 2
=44.2336232 cm²
total surface area
(iii)= 2172.9768 cm²
(round this to however many decimals you need)
I hope this is understandable and useful!

As an estimate we are told 5miles is 8km convert 68 km to miles ?
Answer:
42.5miles
Step-by-step explanation:
68÷8= 8.5
8.5×5= 42.5 miles
we use the numbers given to us because we are finding the estimate.
our estimate is correct because 68km= 42.3 miles
Answer:
The exact answer is 42.25 miles
Step-by-step explanation:
divide 68 by 8 and get 8.5. Multiply 8.5 by the 5 so you get 42.5. Which is a super close estimate.
solve the following equation
3(y – 2) + 2y = 9
Answer:
3( y - 2) + 2y =9
Step-by-step explanation:
It equals 3.
Answer:
y=3
Step-by-step explanation:
3(y-2)+2y=9
3y-6+2y=9
Isolate the variable y by transposing
3y+2y=6+9
5y=15
Simplify
y=3
y = -63 y = 8x + 6
Use Substitution to solve
9514 1404 393
Answer:
(x, y) = (-8.625, -63)
Step-by-step explanation:
Substitute for y.
-63 = 8x +6
-69 = 8x . . . . . subtract 6
-69/8 = x = -8.625
The solution is (x, y) = (-8.625, -63).
Solve the equation: 12(x + 8) = 11x - 5 What is the solution?
Answer:
We conclude that the solution is:
[tex]x = -101[/tex]Step-by-step explanation:
Given the equation
[tex]12\left(x\:+\:8\right)\:=\:11x\:-\:5[/tex]
Expand 12(x + 8): 12x + 96
[tex]12x+96=11x-5[/tex]
Subtract 96 from both sides
[tex]12x+96-96=11x-5-96[/tex]
Simplify
[tex]12x=11x-101[/tex]
Subtract 11x from both sides
[tex]12x-11x=11x-101-11x[/tex]
Simplify
[tex]x=-101[/tex]
Therefore, we conclude that the solution is:
[tex]x = -101[/tex]how is the orientation of and image affected by translation
