Answer:
<u>No, it's not a function.</u>
Step-by-step explanation:
This is not a function because the x-inputs repeat. It would be a function if each x-input was a different number, but the inputs 3 and 4 repeat twice. <u>Therefore, this is not a function.</u>
The mass of the solution is 190 g - 120 g = 70 g. Thus, it's density is 70 g / 50 mL = 1.4 g/mL.
Answer:
Step-by-step explanation:
Conditions
- A diameter must be chosen such that it meete the sidewalk perpendicular to itself.
- The diameter meets the sidewalk at the sidewalk's midpoint.
- The diameter meets the sidewalk such that the diameter is cut into two segments 30+18 and 12
- The sidewalk is cut in 1/2 where the diameter meets the sidewalk as the diagram shows.
- If all these conditions are met, the relationship between the four lines is
Equation
48/12 = x^2
Solution
4 = x^2
sqrt(x^2) = sqrt(4)
x = 2
The length of the sidewalk is 4. Why is it doubled.
Because there are 2 xs of equal length
