Answer:
B. 12π ft.³
Step-by-step explanation:
volume of cylinder = πr²h
= π × 2² × 3
= π × 4 × 3
= 12π
Answer:
64
Step-by-step explanation:
Step 1: Define
9(a + 2b) + c
a = 3
b = 2
c = 1
Step 2: Substitute and Evaluate
9(3 + 2(2)) + 1
9(3 + 4) + 1
9(7) + 1
63 + 1
64
Answer <u>(assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line between the two points by using the slope formula, 
. Substitute the x and y values of the given points into the formula and solve:
Thus, the slope of the line is 
.
2) Next, use the point-slope formula 
to write the equation of the line in point-slope form. Substitute values for 
, 
, and 
in the formula.
Since represents the slope, substitute in its place. Since and represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, it will equal the same thing) and substitute its x and y values into the formula as well. (I chose (-2,0), as seen below.) Then, isolate y and expand the right side in the resulting equation to find the equation of the line in slope-intercept form:
Answer: y=x^2+2
Step-by-step explanation:
y=x^2+2 (answer choice 3) is parabolic and not linear
that is the answer
