Answer:
C is the equation that is perpendicular and goes through the given point.
Step-by-step explanation:
In order to find this, we first need to find an equation with the appropriate slope. Perpendicular lines have opposite and reciprocal slopes. Since the slope of the original line is 1, we need a line with -1 slope. C and D are the only such answers that have this slope.
Next we look for it to fit into the following point slope equation.
y - y1 =m(x - x1)
We use the point (2, 5) as (x1, y1). So we can plug those in the spots that we see above as well as the slope at m.
y - y1 =m(x - x1)
y - 5 = -(x - 2)
Answer:
43988ft^3
Step-by-step explanation:
Given data
Radius= 20ft
Height= 35ft
The expression for the volume of a cylinder is given as
Volume= πr^2h
substitute
Volume= 3.142*20^2*35
Volume= 3.142*400*35
Volume= 43988ft^3
Hence the volume is 43988ft^3
The answer is B because when you solve for x that is what you get
You have
4x² -2x+8 -x²-3x+2
= 4x²-x² -2x-3x +8+2
= 3x²-5x+10
your answer is D
