The water level increases by 0.608 meters per minute when the water is 3.5 m deep
<h3>How to determine the rate?</h3>
The given parameters are:
- Radius, r = 3
- Height, h = 7
- Rate in, V' = 4.3m^3/min
The relationship between the radius and height is:
r/h = 3/7
Make r the subject
r = 3h/7
The volume of a cone is;

This gives

Expand

Differentiate

Make h' the subject

When the water level is 3.5.
We have:

Also, we have:
V' = 4.3
So, the equation becomes

Evaluate the products

Evaluate the quotient
h' = 0.608
Hence, the water level increases by 0.608 meters per minute

#SPJ1
answer:
gradient is 4
Step-by-step explanation:
gradient is another way of saying slope
slope in the math is often used to show the speed of something
it's the m in y= mx+b
make the equation look like
y = mx + b
2y - 8x = -2
2y = 8x - 2
y= (8x-2)/2
y=4x-1
gradient is the number next to x
answer : gradient is 4
In a way, you are adding like terms.
3.5 + 2.7 = 6.2, therefore making the answer 6.2 + x
The brackets can be ignored so you are really just asked 8 x 4 x k. 8 x 4 =32 so you end up with 32k
Answer:
1200
Steps to answer the problem:
1/5 of a minute goes in to 1 minute 5 times
5 x 240 = 1200
