The answer to this question is that the period is 6*pi/5. The period of y = sin(bx) is given by
period = 2pi/b
so with b = 3/5, that is the result.
The resistance of a material is given by the formula R = ρ*
. Where l is the length and S is the area of the surface calculated with the radius, and ρ is the coefficient that indicates the resistance of a material.
If you keep the lenght and radius, and change the material, ρ will still change and the final resistance (R) will change.
Answer: the known variable; the to-be-predicted variable
Step-by-step explanation:
In statistics, linear regression is a technique to model the relationship between two variables ( one independent and other dependent).
It requires some previous data to plot a best fit line.
It is used to predict the values for dependent variable for each independent variable.
Here, independent variable = known variable and dependent variable = is to be predicted
Hence, Linear regression describes the extent to which <u>the known variable</u> predicts <u>the to-be-predicted variable</u>.
Answer:
(1/2)x - y = -2
General Formulas and Concepts:

Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Standard Form: Ax + By = C
Step-by-step explanation:
<u>Step 1: Define equation</u>
Slope-Intercept Form: 2 + (1/2)x = y
<u>Step 2: Find Standard Form</u>
- Rewrite: y = (1/2)x + 2
- Subtract 1/2x on both sides: y - 1/2x = 2
- Factor negative: -(1/2x - y) = 2
- Divide both sides by -1: 1/2x - y = -2
Answers 1. x=3 2. x=-3 3. x=-12 4. x=5 5. x<-5 6.x=-4 All you do is do the opposite opperation
