Drag each sequence to show whether it is a linear function, an exponential function, or
not a function.
I will give you 20 brainiest points!! Please help.
Answers
Answer:
Step-by-step explanation:
From the picture attached,
Option A
From the given table,
Ratio of the 2nd value and 1st value = [tex]\frac{8}{4}=2[/tex]
Ratio of 3rd value and 2nd value = [tex]\frac{16}{8}=2[/tex]
There is a common ratio of 2.
Therefore, the given table will represent an exponential function.
Option B
Given recursive formula of the sequence is,
[tex]A_1=3[/tex]
[tex]A_n=5.A_{n-1}[/tex]
From this recursive formula sequence will be,
3, 15, 75, 375,.......
Therefore, it's an exponential function.
Option C
[tex]F_n=3n+17[/tex]
Given function is in the form of a linear function (y = mx + b),
Therefore, it's a linear function.
Option D
From the given table,
Difference between 2nd value to the 1st value = 8 - 4 = 4
Difference between 3rd value to the 2nd value = 12 - 8 = 4
Therefore, there is a common difference of 4 in each successive term to the previous term.
Hence, the given table represents a linear function.

Answer:
-3/4x + 1/4
Step-by-step explanation:
Given equation of line: y = mx+c,
where m = slope and c = y-intercept
given m = -3/4,x = -5, y=4,
[tex]4 = ( - \frac{3}{4} )( - 5) + c \\ c + 3.75 = 4 \\ c = 0.25 \: or \frac{1}{4} [/tex]
therefore equation of line :
[tex]y = - \frac{3}{4} x + \frac{1}{4} [/tex]
therefore answer is the first one.

Once upon a time I weighed 120 pounds. Now I weigh 225 pounds. What is the percent change?
Answers
Answer:
The percent change is 87.5%. (You're one chonky boi lol)
Step-by-step explanation:
To find the percent change, calculate the difference between the new weight and the old weight and divide that value by the old weight and multiply by 100% to find the percent change. In this case, the equation would be [tex]\frac{225-120}{120}[/tex] * 100% = [tex]\frac{105}{120}[/tex] * 100% = 0.875 * 100% = 87.5%, so the correct answer is a percent change of 87.5%.
Answer:
[tex]53\frac{1}{3}[/tex] %
Step-by-step explanation:
[tex]\frac{120}{225} =\frac{y}{100}[/tex]
225 × y = 120 × 100
225y = 12000
225y ÷ 225 = 12000 ÷ 225
[tex]y=53\frac{1}{3}[/tex]

Rachel needs to buy some pencils. Brand A has a pack of 28 pencils for $5.29. Brand B has a pack of 48 pencils for $8.47 . Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.
Answers
Answer:
Hence Brand B is the better buy, since the unit cost is smaller than A
Step-by-step explanation:
Given data
Brand A
Has a pack of 28 pencils for $5.29
unit cost
=5.29/28
=$0.19
Brand B
Has a pack of 48 pencils for $8.47
unit cost
=8.47/48
=$0.18

In the given rectangle
US = 4x - 16 and RO = x + 2, find RT.
Show all the work
Answers
Answer:
RT = 24
Step-by-step explanation:
Diagonals of rectangles bisects each other and equal in length (congruent) to each other.
Thus
US = RT
US = 2(RO)
4x - 16 = 2(x + 2)
4x - 16 = 2x + 4
2x = 20
x = 10
RT = 2(RO)
= 2(x+2)
= 2(10 + 2)
= 2(12)
= 24

Part C
1) 4 pounds of apples + 8 pounds of bananas
2) 8 pounds of apples + 6 pounds of bananas
Step-by-step explanation:
Part A
The amount Tony has to buy apples and bananas = $14
The cost of apples per pound = $2
The cost of bananas per pound = $1
Let 'a' and 'b' represent the number of apples and bananas Tony buys respectively, we have;
2·a + b ≤ 14
Part B
In order to plot the inequality, we make one of the variables the subject of the inequality as follows;
b ≤ 14 - 2·a
The above inequality can be plotted with Microsoft Excel and the feasible region shaded as shown in the attached diagram
Part C
Two possible combinations of pounds of apples and bananas that Tony can buy are;
1) 4 pounds of apples and 8 pounds of bananas which gives 2 apples and 8 bananas
2) 8 pounds of apples and 6 pounds of bananas which gives 4 apples and 6 bananas

Answer is in picture and explanation below.
Step-by-step explanation:
Continuing from the picture,
Area of Metal base = Area of Bigger Circle - Area of Hollow Circle
=
[tex]1156\pi {mm}^{2} - 225\pi {mm}^{2} \\ = 931\pi {mm}^{2} [/tex]
Volume of Cylinder = Area of Metal base x Height (Length in this case)
=
