When the dept of the water is 3/5 of the height of the cone, the radius of the water's surface is 3/5 of the radius of the cone: 1.2 ft. The rate of change of depth is equal to the rate of change of volume divided by the area of the surface:
dh/dt = (dV/dt)/A = (dV/dt)/(π·r²)
= (3/2 ft³/s)/(π·(1.2 ft)²)
= 25/(24π) ft/s ≈ 0.3316 ft/s
Answer:
B. They are perpendicular
Step-by-step explanation:
calculate the gradient of (-6, -1) and (-11, 1)
m= y2 - y1/ x2 - x1
= 1 - (-1)/ -11 -(-6)
m = <u>-</u><u>2</u><u>/</u><u>5</u>
then you find the gradient of the other points in the same way
m = y2 - y 1/ x2 -x1
= -13 -(-8)/ -5 -(-3)
m = 5/2
to prove that they are perpendicular
m1×m2 = -1
-2/5 × 5/2 = <u>-</u><u> </u>1
hence they are perpendicular
