Answer:
r = 13
Step-by-step explanation:
The first step is to find b from y=mx=b using m=4/3 and (-4,8)
After solving the equation, b will equal -16/3 making the final equation be
Using the equation, you can solve for r.
This will bring the answer being r = 13
Your answer is unlikely. That would be a 1 out of 10 chance.
Answer:
Step-by-step explanation:
From similar triangles, see diagram in attachment
We solve for to obtain,
The formula for calculating the volume of a cone is
We substitute the value of to obtain,
This implies that,
We now differentiate both sides with respect to to get,
We were given that water is drained out of the tank at a rate of
This implies that .
Since we want to determine the rate at which the depth of the water is changing at the instance when the water in the tank is 8cm deep, it means .
We substitute this values to obtain,
The median is the 6 th element of the 11 th
that is 7
