Answer:
y = 13.50x + 20
y = 17x + 6
The cost is the same after 4 hours.
Step-by-step explanation:
I don't really know what to say except you just have to replace x with 4 and then work it normally from there.
The answer is 5/9. I showed a bit more work on the other post
Answer:
<h2>
m = -¹¹/₄</h2>
Step-by-step explanation:
The equation of a line with slope of <em>m</em> and y-intercept of <em>b</em> is: y = mx + b
b = 2 and line contains the point (4, -9), so:
-9 = m×4 + 2 {subtract 2 from both sides}
-11 = 4m {divide booth sides by 4
m = -¹¹/₄
By knowing the circumference of the base of the cone, we see that the radius is 4 centimeters.
<h3>
How to find the radius of the cone?</h3>
Notice that in the first figure, the length of the arc AB is L = 8π cm.
Then, that arc will be the bottom part of the cone. Then we can see that the circumference of the base of the cone will be equal to the length of the arc.
And remember that for a circle of radius R (like the base of the cone), the circumference is:
C = 2πR.
Then we will get:
8π cm = C = 2πR
( 8π cm)/ 2π = R
4cm = R
The radius of the cone is 4cm.
