Answer:
192 cm^3/min
Step-by-step explanation:
Differentiating the volume expression, we get ...
dV/dt = 2xh(dx/dt) +x^2(dh/dt)
We are given that ...
x = 4 cm, dx/dt = 2 cm/min, h = 15 cm, dh/dt = -3 cm/min
Putting these values into the formula for volume rate of change, we get ...
dV/dt = 2(4 cm)(15 cm)(2 cm/min) +(4 cm)^2(-3 cm/min)
= 240 cm^3/min -48 cm^3/min
dV/dt = 192 cm^3/min
Answer:
y=5x+8
Step-by-step explanation:
You need have the slope-intercept formula:
y=mx+b
m=slope
b=y-intercept
You replace the m and b with the slope and y-intercept which is 8
y=5x+8
Hope this helps!

Answer:
Flying squirrel have to glide is for 9.8 meters approximately.
Step-by-step explanation:
Here we can use Pythagoras theorem.
Height is 9 , base is 4.
We need to find the hypotenuse measure.
So, let's use Pythagoras theorem 
Plug in a as 9 and b 4.
Simplify the left side of the equation
Take square root on both sides.
c=9.8 meters.
