A cone with volume 246 ft cubic if the height is 15 find the radius
Liula [17]

Answer:

r = 3.95 ft

Step-by-step explanation:

Volume of cone = \frac{1}{3} \pi r^{2} h = 246 ft³

246 = \frac{1}{3} * \frac{22}{7} * r^2 * 15

r² = \frac{246*3*7}{22*15*5}

r = \sqrt{15.65}

r = 3.95 ft

Left on together, the cold and hot water faucets of a certain bathtub take 8 minutes to fill the tub. If it takes the cold wate
MArishka [77]
Cf=cold faucet rate
hf=hot faucet rate

cf*18min=1 tub
(cf+hf)*8min=1 tub
cf+hf=1tub/8min
cf=1tub/18min
hf=(1/8-1/18)tubs per minute
hf=5/72

It takes 14.4 minutes.

Think about the function f(x) = 3 - 2x. What does the notation f(0) mean? f(0) = What is the special name of f(0)?
mel-nik [20]

Notation f(0) means the graph crosses y-axis where x becomes zero

or simply y-intercept


f(x) = 3 - 2x

put x = 0

f(0) = 3 - 2(0)

f(0) = 3 - 0

f(0) = 3


Special name of f(0) : <em>y-intercept</em>

Darko found the distance between points A(3,-4) and B(-1,3) his work is shown below
alex41 [277]

In this question , Darko have to find the distance between A(3,-4) and B (-1,3) .

He uses the correct formula, which is

d = \sqrt{ (x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}

And on substituting the values , we will get

d = \sqrt{ (-1-3)^2 + (3- (-4))^2 }

And in this line, Darko did the mistake .
