What is arithmetic Progression?The difference between every two subsequent words in a sequence is the same; this is known as an arithmetic progression (AP). An equation for the previous block of the AP may be derived from this kind of development. For instance, the sequence 2, 6, 10, 14,... is a mathematical progression (AP) because it fits a pattern where every other number is acquired by adding 4 to the respective period.
The given data is,
-10, 20, -40
From -10 to 20 it is multiplied by 2 with a positive sign, and from 20 to -40 it is multiplied by 2 with a negative sign. Similarly, the next two numbers are 80 and -160.

Find f(g(3)). PLEASE HELP me asap!!!!! thank you so so much!!!! *will give brainliest*
=========================================================
Explanation:
Start at x = 3 on the x axis. Move up until you reach g(x), then move to the left to hit the y axis. You should arrive at y = 3.
That y value is the input to the f(x) function.
Plugging x = 3 into the f(x) function has us draw a vertical line down to f(x) and then go horizontally until we reach y = -2.

We have a right triangle triangle. We can use trig to find the missing length.
Step 2: Identify Variables
POV from the angle measure

Opposite = 13
Adjacent = x
Step 3: Solve for x

A recipe requires 1 2/3 cups of sugar. If Mrs.Marina is going to make one and one half of the recipe, then how much sugar does she need
Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.
What is proportion ?
A proportion is an equation based on the equality of two ratios.
Here it is given that :
A recipe requires 1 (2/3) cups of sugar.
That is 1 recipe requires = 1(2/3) cups of sugars
= 5/3 cups of sugar
Now, Marina is going to make one and one half of the recipe and to find the sugar he needed we simply multiply 1(1/2) both the sides :
1 recipe requires = 5/3 cups of sugar
1(1/2) recipe requires = (5/3) x 1(1/2) cups of sugar
3/2 recipe requires = (5/3) x (3/2) cups of sugar
3/2 recipe requires = 5/2 cups of sugar or 2.5 cups of sugar.
Therefore, Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.

The length between the bases on a baseball field is 90 feet. A scale drawing shows the distance between the bases as 2 inches. One inch on this drawing
equals how many feet?
Enter your response here:
Answer:
1 inch of drawing = 45 feet
Step-by-step explanation:
Given that:
Length between the bases on a baseball field = 90 feet
As per the scale drawing, the distance between the bases is equal to 2 inches.
To find:
Length of one inch on the drawing is equal to actual length of how many feet?
Solution:
First of all, let us learn about the scale drawings.
Scale drawings are a way to represent the big real world measurements on a paper.
Therefore, small measurements are used to represent the bigger real world measurements.
Here, it is given that:
2 inches on scale is equal to 90 feet of actual length.
Therefore,
1 inch on scale is equal to [tex]\frac{90}{2}[/tex] = 45 feet of actual length.
Therefore, 1 inch of drawing = 45 feet

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Norma is a salon owner. Yesterday, she did 1 haircut and colored the hair of 2 clients, charging a total of $217. Today, she did 2 haircuts and colored the hair of 1 client, charging a total of $155. How much does Norma charge for her services? PLEASE ANSWER
Answer:
Cost of haircut = $93
Cost of colouring hair = $31
Step-by-step explanation:
Let
Cost of haircut = x
Cost of colouring hair = y
The equations
x + 2y = 217 (1)
2x + y = 155 (2)
From (1)
x = 217 - 2y
Substitute x = 217 - 2y into (2)
2x + y = 155
2(217 - 2y) + y = 155
434 - 4y + y = 155
-3y = 155 - 434
-3y = -279
y = -279 / -3
= 93
y = $93
Substitute y = 93 into (1)
x + 2y = 217
x + 2(93) = 217
x + 186 = 217
x = 217 - 186
= 31
x = $31
Cost of haircut = $93
Cost of colouring hair = $31

And, [tex]NS =6,\ SM=2,\ RM=x,\ NR=y,\ RS=z[/tex]
Now,
We have right angle [tex]\triangle MRN[/tex],
Using Pythagoras theorem,
[tex]x^2+y^2=8^2[/tex]
[tex]x^2+y^2+=64\[/tex] [tex].....(i)[/tex]
Now, We have right angle [tex]\triangle RSN[/tex],
Again Using Pythagoras theorem,
[tex]z^2+6^2=y^2[/tex]
⇒[tex]z^2=y^2-36[/tex] [tex].....(ii)[/tex]
Now, We have right angle [tex]\triangle RSM[/tex],
Again Using Pythagoras theorem,
[tex]z^2+2^2=y^2[/tex]
⇒[tex]z^2=x^2-4[/tex] [tex].....(iii)[/tex]
Now comparing equation [tex](ii)[/tex] and equation [tex](iii)[/tex],
We get,
[tex]x^2-4=y^2-36[/tex]
We get,
[tex]x^2-y^2=-36+4[/tex]

Now,
Adding equation [tex](i)[/tex] and equation [tex](iv)[/tex], i.e.
[tex]x^2+y^2+=64[/tex]
[tex]x^2-y^2=-32[/tex]
We get,
[tex]2y^2=96[/tex]
[tex]y^2=48[/tex]
[tex]y=\sqrt{48}[/tex]
[tex]y=4\sqrt{3}[/tex]
So, the value of [tex]y[/tex] is [tex]4\sqrt{3}[/tex]
Hence, we can say that the value of [tex]y[/tex] will be [tex]4\sqrt{3}[/tex] which is given in option (b).

2x + 4y = 8
x = 3y - 6
2x + 4y = 8
2 ( 3y - 6 ) + 4y = 8

Gabriel is buying bagels for a family gathering. Each bagel costs $1.75. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.
The independent variable, x, represents the
, and the dependent variable is the
, because the
depends on the
.
A function relating these variables is N(x) =N(x)=
.
So N(14) =N(14)=
, meaning 1414
.
Answer:
Independent Variable: Number of bagels bought
Dependent Variable: Total cost because it depends on the number of bagels bought.
Function: N(x)=1.75x
So, if x is the number of bagels bought, N(14) means that 14 bagels were bought. So you multiply 14 by the price; 1.75. So, N(x)=1.75*14 = $24.5
Step-by-step explanation:
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is V(x) =1.75x.
So V(14) = 24.5, meaning 14 bagels will cost 24.5 dollars.
