Answer:
at y = 18 units
Step-by-step explanation:
An arch has the equation y=-2/81x^2+18. Find it’s maximum height
This is a parabolic function
Maximum at the vertex
x = -0/(2*(2/81)) = 0
max at y = 18 units
Answer:
you will have to find the slope in the y= mx+b form.
you can find the slope also by looking at the graph and looking at the rise over run
Answer:
Given:
(i) Wendy reduced her daily commute time by 75% by learning how to fly.
(ii) Previously, it took her 'm' minutes to commute.
To find:
(i) Wendy's commute time in minutes after she learned how to fly.
Solution:
Given that earlier it took Wendy 'm' minutes to commute.
After learning how to to fly, the commute time reduced by 75%.
So, time taken now = (100-75)% of previous time
= 25% of 'm' minutes
= \frac{25m}{100}
100
25m
= \frac{m}{4}
4
m
So, the time taken by Wendy now is \frac{m}{4}
4
m
minutes.
If the mug costs $8 and Kendra got back $0.56 back for paying $9 than to find the tax rate you would divide $0.56 by $8 which would end up to be 0.07 percent as the tax rate.
