Answer:
The value of function w(2b + 6) is 6b + 26
Step-by-step explanation:
Given function as :
w(x) = 3 x + 8
I.e y is the function of x
Now for every value of x in the function , the value of function w(x) changes
Now for x = 2b + 6
w(2b + 6) = 3 × (2b + 6) + 8
Or, w(2b + 6) = 6b + 18 + 8
I.e w(2b + 6) = 6b + 26
Hence The value of function w(2b + 6) is 6b + 26 Answer
Answer:
18

Answer:
Therefore,the level of paint is rising when the bucket starts to overflow at a rate cm per minute.
Step-by-step explanation:
Given that, at a rate 4 cm³ per minute,a cylinder bucket is being filled with paint
It means the change of volume of paint in the cylinder is 4 cm³ per minutes.
i.e cm³ per minutes.
The radius of the cylinder is 20 cm which is constant with respect to time.
But the level of paint is rising with respect to time.
Let the level of paint be h at a time t.
The volume of the paint at a time t is
Differentiating with respect to t
Now putting the value of
To find the rate of the level of paint is rising when the bucket starts to overflow i.e at the instant h= 70 cm.
Therefore, the level of paint is rising when the bucket starts to overflow at a rate cm per minute.
