V=3.14(R)^2(H)
this is the formula to find the volume of a cylinder
It is not a function because there can't be two of the same number on the x-axis.
Answer:
Difference between Observational and Experimental Data
The data collected in the study is observational data.
Step-by-step explanation:
In an experimental study, the data collected is divided into two groups. One group is the control group. The other group is the treatment group (also known as the experimental group). Data is gathered about the groups in order to compare their different outcomes and to draw conclusions if there is any causality based on the two variables. With observational data, the researcher is interested in observing the variables to determine if there is any correlation.
y=mx+b
because the y=2x-1, so m=2
because we know (4.2), so we can bring it in to the function:
2=2x4+b
2=8+b
b=-6
So the other one is: y=2x-6
in other way it's 2x-y=6
Which means the answer is B.
Answer:
Step-by-step explanation:
1. Subtract 10 from both sides. Then:
2. Divide both sides by -2. Notice that the direction of the symbol of the inequality will change. Then:
3. Add 22 to both sides. Then:
4. Divide both sides by -7. Notice that the direction of the symbol of the inequality will change. Then:
5. Subtract 30 from both sides. Then:
6. Divide both sides by -5. Notice that the direction of the symbol of the inequality will change. Then:
7. Subtract 13 from both sides. Then:
8. Add 12 to both sides. Then:
