➷ A) The number of bracelets sold is the independent variable and the profit is the dependent variable
B) f(b) = 2b - 200
C) Substitute the value in:
f(b) = 2(100) - 200
The profit would be $0
D) i don't actually know this part sorry :(

Answer: B
Step-by-step explanation: 14 1/5 - 2 5/6 =11 11/30
rounded is 11
1. Simplify= xy^3
2. Factorise= (2x+1)(2x-1)
3.
4.
5. Estimate= 415.96
6. Highest Common Factor
70= -70,-35,-14,-10,-7,-5,-2,-1,1,2,5,7,10,14,35,70
98= -98,-49,-14,-7,-2,-1,1,2,7,14,49,98
7. Expand: 4-4x+x^2 Simplify: x^2-4x+4
8.
9. This is actually the easiest you take both the mass and volume and divide them :) which would be 500g<span>÷25cm^3=20g/cm3 </span>
10.
The ones I didn't answer I am not sure about and don't wanna give you any wrong answers :) Hope I helped though!
Answer: Fourth option: periodic with a period of 3 and an amplitude of about 10
Step-by-step explanation:
In the data, we can see that our values go from values around 30, to values around 10, and then it goes up again,
The period will be the distance between two points where we have the maximum value.
The first maximum, 30, is on day 2.
The second maximum, 28, is at day 5
Then the period is something around 5 - 2 = 3
The amplitude will be half the difference between the maximum and the minimum.
The maximum is around 30.
The minimum is around 10.
The amplitude is about:
A = (30 - 10)/2 = 20/2 = 10
Then the period is about 3 and the amplitude is about 10.
The correct option is the fourth one.
