The perpendicular slope is the negative reciprocal of the slope of the line it is perpendicular to. Therefore, the slope would be the negative reciprocal of -1/2 which would be 2.
From there, you plug in the coordinate into x and y and solve for b;
5 = 2 * -3 + b
5 = -6 + b
b = 11
Therefore the equation is;
y = 2x + 11

Answer:
Surface area of the whole figure
Step-by-step explanation:
The surface area of the figure :
Surface area of the cylinder(excluding top)+Surface area of the cone(excluding bottom)
Radius of the cylinder=3 inch and Height of cylinder=13 inch
Surface area of the cylinder with one circular face
As, 
Surface area of the cone excluding base:
l= slant height=5 inch r= radius= 3 inch
Surface area of the cone =
Total surface area of the whole figure
Answer:
D.the treatment group (placebo or reading strategies)
Step-by-step explanation:
This cognitive psychologists wants to find out if better reading strategies when taught to students would have any effect on their test scores.
So the dependent variable in this experiment would be the test scores that she wants to find from the test.
While the independent variable would be the treatment group which is the placebo or treatment. The psychologist wants to measure outcomes in this dependent variable using changes in the independent variable (placebo/treatment).
