Answer:
The rate at which both of them are moving apart is 4.9761 ft/sec.
Step-by-step explanation:
Given:
Rate at which the woman is walking, = 3 ft/sec
Rate at which the man is walking, = 2 ft/sec
Collective rate of both, = 5 ft/sec
Woman starts walking after 5 mins so we have to consider total time traveled by man as (5+15) min = 20 min
Now,
Distance traveled by man and woman are and
ft respectively.

As we see in the diagram (attachment) that it forms a right angled triangle and we have to calculate .
Lets calculate h.
Applying Pythagoras formula.
⇒
⇒
Now differentiating the Pythagoras formula we can calculate the rate at which both of them are moving apart.
Differentiating with respect to time.

ft/sec
⇒ ft/sec
So the rate from which man and woman moving apart is 4.9761 ft/sec.
Answer:
Hey! The answer is 25,4 centimeters.
Step-by-step explanation:
In a linear function you can use y=mx+n
So if x = hours and y= height.
You know that
So:
If you multiply (24,8=26m +n) x-1
It is: -24,8 = -26m -n
Adding up the other equation
-24,8 = -26m -n
<u>27,8 = 11m + n</u>
<u>3 = -15m</u>
<u>m= -0,2</u>
So
27,8 = 11 x 0,2 + n
27,8 = -2,2 + n
30 = n
This results that te linear function for this equation is:
y = -0,2x + 30
The answer is
y=23(-0,2) + 30
y=-4,6+30
y=25,4
To find the lateral area of a cone, use this formula:
where r is the radius (in this case, 11) and h is the height (in this case, 26)
