We have to find the factor of this expression which matches to the options.
Find the measure of the supplementary angles that satisfy each case. m<1 is less than m<2 by 40 degrees
Answer:
One angle is 70 and the other angle is 110
Step-by-step explanation:
x + 40 = y
x + y = 180 Supplemental angles add to 180
Substitutes x + 40 into the second equation by y
x + x + 40 = 180 Combine like terms
2x + 40 = 180 Subtract 40 from both sides
2x = 140 Divide both sides by 2
x = 70
Substitute in 70 for x in either of the original 2 equations
x + y = 180
70 + y = 180 Subtract 70 from both sides
y = 110
m1=70
m2=110
supplementary angles are two angles that add up to 180 so all you need to do is make an equation to find the answer.
we can make m1=x and m2 = y
x is less than y by 40 degrees so y-40=x
then we use the equation x+y=180 and replace x with what we found out and solve for y.
(y-40)+y=180 ---> 2y -40 = 180 ---> 2y = 220 ---> y=110
x+y=180 ---> x+110=180 ---> x=70
the function f(x)=(4x-8)^2 is the image of g(x)=x^2 after a set of transformations have occurred. which of the following describes the transformation that occurred to g(x)
The transformations that occurred to g(x) are horizontal stretch by a factor of 4 and a down translation by 4 units
How to describe the transformation that occurred to g(x)?The equation of the functions are given as
f(x)= (4x - 8)^2
g(x) = x^2
Start by stretching the function g(x) horizontally by a scale factor of 4
This is represented as
g'(x) = g(4x)
So, we have
g(4x) = (4x)^2
This gives
g'(x) = (4x)^2
Next, we translate the function down by 8 units
This is represented as
f(x) = g'(x - 8)
So, we have
f(x) = (4x - 8)^2
Hence, the transformations that occurred to g(x) are horizontal stretch by a factor of 4 and a down translation by 4 units

This means that
Domain: -∝ < x < ∝
An absolute value function is represented as
f(x) = a|x - h| + k
Where
Vertex = (h, k)
By comparison, we have

b + 17.3 ≥ −2.8
b + 17.3 ≤ −2.8
−2.8 + b < 17.3
The linear inequality for the statement " the sum of a number and 17.3 is at least −2.8" is b + 17.3 ≥ - 2.8 which is option B
We are given that the sum of a number and 17.3 is at least −2.8 and we have to form a linear inequality from the information provided
Let the number be b
so, the sum of two numbers would be
b + 17.3
It is given that the sum should be at least - 2.8
this means the sum is either equal to - 2.8 or sum is more than -2.8
So, the linear inequality equation comes to be
b + 17.3 ≥ - 2.8

A mole is a unit of measurement in chemistry. If 1 mole contains 6.02×1023 particles, how many particles are in 12 of a mole?
The number of particles which are in 12 moles of any substance given the premise that; 1 mole contains 6.02×1023 particles is; 7.224 × 10²³.
What is the number of particles in a separate substance given that one mole contains 6.02×10²³ particles?It follows from the task content that 1 mole contains 6.02×1023 particles, and hence, the number of particles in 12 moles is to be determined.
On this note, it follows from proportion that since 1 mole contains 6.02×1023 particles, then, the number of particles is 12 moles is;
= 12 × 6.02 × 10²³
= 72. 24 × 10²³
= 7.224 × 10²³.
Ultimately, The number of particles which are in 12 moles of any substance given the premise that; 1 mole contains 6.02×1023 particles is; 7.224 × 10²³.

a:b = b:c then b is called mean proportional and b2 = ac

d is fourth proportional to numbers a, b, c if a:b = c:d
Step-by-step explanation:
Answer: GoodMorning: ) ✨ According to proportion, if two sets of given numbers are increasing or decreasing in the same ratio, then the ratios are said to be directly proportional to each other. Proportions are denoted using the symbol '::' or '='. For example, 2:5 :: 4:8 or 2/5 = 4/8.
Two values x and y are said to be directly proportional to each other when the ratio x:y always remains the same. Example : If we buy two pen for 50 Rs. It will cost us 100 Rs for four pen. Two values x and y are said to be inversely proportional to each other when the ratio x:y1 always remains the same.

The mistake made by the student was using the composition f ° g(x) instead of g ° f(x). The correct form is g( f(0)) = - 9 / 2.
How to find the procedure error associated to a composition of functions
In this question we find two functions, with which we should perform an operation known as composition. Composition consists in substituting the input of a function by the other function. The operation is defined by the following expression:
f ° g (x) = f [g (x)]
Herein we must determine the mistake done by the student on the composition. If we know that f(x) = (3 · x - 7) / 4, g(x) = 2 · x - 1 and x = 0, then the value of g(f (0)) is:
g ° f (x) = g (f (x))
g ° f (x) = 2 · [(3 · x - 7) / 4] - 1
g ° f (x) = (3 · x - 7) / 2 - 1
g ° f(x) = (3 / 2) · x - 7 / 2 - 1
g ° f(x) = (3 / 2) · x - 9 / 2
g ° f(0) = (3 / 2) · 0 - 9 / 2
g ° f(0) = - 9 / 2

Tim earns spending money by doing odd jobs for his neighbors. The table shows how much he is paid for each job. At the beginning of the month, Tim has $50. He mows 2 lawns and washes 1 car. Then, he buys two video games that cost $15 each and a sweatshirt that costs $35. Write an addition equation using integers to represent the situation. How much money does Tim have left?
Based on the amount that Tim had at the beginning of the month, the mowing of the lawn and washing of the car, the equation that represents the situation is b. 50 + 12 + 12 + 9 + (-15) + (-15) + (-35).
The amount of money that Time has left is $18
How to find the amount left?Tim gets $12 for every lawn he mows and $9 for every car he washes.
The amount he gets is:
= Amount started with + payment for mowing lawn + payment for mowing another lawn + payment for car wash
= 50 + 12 + 12 + 9
When the expenses of the video games and sweatshirt are thrown in, the formula becomes:
= 50 + 12 + 12 + 9 + (-15) + (-15) + (-35)
The amount that Tim is left with is:
= 50 + 12 + 12 + 9 + (-15) + (-15) + (-35)

In a class of 32 students
The mean height of the 14 boys is 1.56 meters
The mean of all students is 1.515 meters
Work out the mean height for the girls
When the the mean height of the 14 boys is 1.56 meters and the mean of all students is 1.515 meters then the mean height for the girls will be 1.48.
How can the mean height for the girls be calculated?From the question, we were given total number of students as 32
But the mean can be calculated as the ratio of all the sum of all the data to the total number of data,
the total height of all students= (32*1.56)=48.48
total height of 14 boys=(14*1.56)=26.64
number of girls is (32-14)=18
The mean height for the girls will be (26.64/1118)=1.48
Therefore, When the the mean height of the 14 boys is 1.56 meters and the mean of all students is 1.515 meters then the mean height for the girls will be 1.48.

SUBMIT
New data point is residual.
When a data point is added or removed from the whole dataset, it might cause a significant change in the regression equation by either changing the slope or the relationship coefficient existing between the variables.
An influential point is one that changes the relationship existing between the dependent and the independent variables significantly in either direction.
Since the new observed data point decreases the slope of the regression line but increases the correlation coefficient existing between the independent and the dependent variable, we can probably say that the new data point is an influential point.

When does a graph represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y. Vertically aligned points mean that a value of x is mapped to multiple values of y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.
For this problem, we have that:
The circled graphed has vertically aligned points, that is, values of x inside the circle are mapped to multiple values of y, hence the graph is not a function.The other two graphs have no vertically aligned points, meaning that each value of x is mapped to only one value of y, hence they are functions.Hence the circled graph given at the end of the answer is not a function of x.
