Answer:
The area of the resulting cross section is 
Step-by-step explanation:
we know that
The resulting cross section is a circle congruent with the circle of the base of cylinder
therefore
The area is equal to
we have
-----> the radius is half the diameter
substitute the values
Answer:
B 5
Step-by-step explanation:
it is the same ratio as the red
To write the function correctly, it is important to assign variables correctly and understand the situation of the problem clearly. For this, we let y the number of people and x as the number of songs played.
At x = 0 y = 567
at x = 1 y = 567 - 567(1/3)
at x = 2 y = 567 - 567(1/3)(1/3)
at x = 3 y = 567 - 567(1/3)(1/3)(1/3)
Therefore, the number of people left after x songs would be represented by the equation:
y = 567 - 567(1/3)x
y = 567 ( 1- x/3 )
Answer: All i know is you have to multiply all of those numbers because its area
Step-by-step explanation:
Answer:
y = x + 2
Step-by-step explanation:
First, find the slope.
(y2 - y1 / x2 - x1)
I'm going to use (0,-2) and (2,0) as my points.
Find the slope.
(-2) - 0 / 0 - 2= -2 / -2 = 1
So the slope is 1.
Now find the y-intercept.
Y-intercept is 2.
Now substitute it into the slope-intercept form equation. (y = mx + b)
y = x + 2
