Answer:
Step-by-step explanation:
A) For the city of Everettt, y-intercept represent the number of chrome books they started with.
y - intercept = 550
Everett started the 2016 year with 550 chrome books
B) y = 50x + 300
Explanation: They stared with 300 books at 2016. This will be the y-intercept
Rate of change = 50 books per year which will the slope
m = 50 and b = 300
y = mx + b
y = 50x + 300
Hint: y- intercept is where x-coordinate =0
The volume of a cone uses the following formula:

Our diameter is 20 feet, so divide this by 2 to find the radius:

We now have all of our values need to fill in the formula. Plug in these values:




The volume of the cone is
1780 cubic feet.
Given:
The x and y axis are tangent to a circle with radius 3 units.
To find:
The standard form of the circle.
Solution:
It is given that the radius of the circle is 3 units and x and y axis are tangent to the circle.
We know that the radius of the circle are perpendicular to the tangent at the point of tangency.
It means center of the circle is 3 units from the y-axis and 3 units from the x-axis. So, the center of the circle is (3,3).
The standard form of a circle is:

Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting
, we get


Therefore, the standard form of the given circle is
.
