Answer:
<u>Fred.</u>
Started hang gliding at a height of 700 ft and descends 15 feet every seconds
<u>Gene</u>
Started hang gliding at a height of 575 ft and descends 10 feet every seconds
Step-by-step explanation:
The function that models Fred's hang gliding is 
The initial value is 700 feet. This Fred was 700 feet above see level before he starts descending.
The rate of descent is -15 ft/s. This means Fred descends 15 feet in one second.
From the table the initial height is 575 ft. This means Gene was 575 feet above sea-level at the beginning of the hang gliding.
The rate of descent is 
ft/s.
This means that in every seconds, Gene descends 10 feet.
Answer:
Z = 20
Step-by-step explanation:
3 x 20 = 60
60 - 12 = 48
7/4 and 3 because they are positive
Answer:
Step-by-step explanation:
Hello, let's say that the price was P, a real number.
After 20% discount it become P - 20% * P = P* (1-20%) = P * (1 - 0.2)
= P * 0.8
And then we take 15% for the VAT, the new price become P * 0.8 * ( 1 + 15%)
= P * 0.8 * 1.15
And this is equal to 22080, so
P * 0.8 * 1.15 = 22080
and the amount of the VAT is P *0.8 * 0.15
Hope this helps.
Thank you.
Answer:
Step-by-step explanation:
The logistic function of population growth, that is, the solution of the differential equation is as follows:
We use this equation to find the value of r.
In this problem, we have that:
So we find the value of r.
Applying ln to both sides of the equality
So
The differential equation is
