Answer:
1. 2*(3)^x This is because he starts off with two friends (so it's times 2) and each person shares it with 3 people (the 3) each day (x is time in days)
2. The same thing but different numbers, this time it's 10 people at first but only sharing to 2 people
10*(2)^x
3. Can't help you on this one, just use a graphing software or something or whatever they tell you to use
The first three points are given to you for Ben, but for Carter its
Day # of Shares
0 10
1 20
2 40
4. Plugin x values for 3 and 10
Ben: 2(3)^3 = 54 and 2(3)^10 = 118098
Carter: 10(2)^3 = 80 and 10(2)^10 = 10240
Amber: 3(4)^3 = 192 and 3(4)^10 = 3145728
5. The original graph and the new graph of Amber is the same except for that the graph is moved up 45 units up because Amber shared it with 45 people flat at her grandma's living facility
6. Amber's post obviously grows the fastest. This is true because she has the greatest growth value and she also has a good headstart of 45 elderly people.
7. This one is up to you, if you want more views in general then just agree with Amber, but if you want less view but with a good starting amount, then agree with Carter. Ben is a good mix if you can't decide or don't care
Answer:
If XY = -1 then Y = -1 / X
Substitute the given values of X into the above formula and solve for Y:
X = 1 ⇒ Y = -1
X = -1 ⇒ Y = 1
X = 1/2 ⇒ Y = -2
X = -1/2 ⇒ Y = 2
X = 1/3 ⇒ Y = -3
X = -1/3 ⇒ Y = 3
Additional points:
X = 2 ⇒ Y = -1/2
X = -2 ⇒ Y = 1/2
If X = 0 then Y = 1/0 which means the function is undefined, therefore the curve will get close to Y = 0 (y-axis) but will not touch it.
If Y = 0 then 0 = -1/X which is impossible, therefore the curve will get close to X = 0 (x-axis) but will not touch it.
Answer:
C
Step-by-step explanation:
It’s convenient that there are only two <em>x</em> values you need to check, -2 and 2. Just insert it to see what <em>y</em> is appropriate.
x = -2: y > 6 + 3 = 9 (and y > -2 + 2 = 0 which is redundant here)
x = 2: y > 2 + 2 = 4 (and y > -6 + 3 = -3 which is redundant here)
So, neither B nor D is in the solution set with 5 < 9 and -5 < 9.
A isn’t in the solution set either with -5 < 4.
C is in the solution set with 5 > 4.
Answer:
360 in^3 (360 inches squared)
Step-by-step explanation:
Find area of each surface:
8 in*9 in=72 in^2
15 in*9 in=135 in^2
17 in*9 in=153 in^2
then, add up all the numbers:
72+135+153=360 in^3
All the multiples of 18 and 30
18: 1,2,3,6,9,18
30: 1,2,3,5,6,10,30
The first three common ones are: 1,2 and, 3
