Answer:

C

Step-by-step explanation:

The volume of a cone is:

(π)(r)^2(h/3)

The diameter is given as 8cm but we need the radius and the radius is half of the diameter meaning 4 cm.

And the height is 9cm

(3.14)(4)^2(9/3)

(3.14)(16)(3)

(3.14)(48)

150.72

Closest to C

Hope this helps :)

Step-by-step explanation:

here's your solution

=> volume of circular cone = (1/3)πr^2h

=> radius = 4 cm ,, height = 9 cm

=> volume of cone = (1/3)*(22/7)*16*9

=> volume of circular cone = 150.8 cm^3

hope \: it \: helps

Analyze the end behavior of both functions.
igor_vitrenko [27]

Answer:

The end behaviour of all the functions is same ie they all tend to zero.

Step-by-step explanation:

In every option the function f(x)is a linear function which tends to infinity at the  end(as x tends to infinity).Now the function g(x)in every option is just the reciprocal of f(x).As we all know

\lim_{n \to \infty} f(x)=∞

then

\lim_{n \to \infty} 1/f(x)=0

2x+y=3<br>x-y= 1<br><br>solve the equation ​
svetlana [45]

Answer:

x = 4/3

y = 1/3

Step-by-step explanation:

System of equations! This is set up really well to make the second equation equal x then substitute.

x - y = 1

x = 1 + y

and then our substitution:

2 (1+y) + y = 3

and solve:

2 + 2y + y = 3

3y + 2 = 3

3y = 1

y = 1/3

And now we can substitute that value into one of our equations:

x - (1/3) = 1

x = 4/3

Next we should check by substituting these values into both of our equations:

2 (4/3) + (1/3) = 3

9 / 3 does equal 3 !

(4/3) - (1/3) does equal 1 !

Therefore, x = 4/3 , and y = 1/3

Draw a line through the point (2, 0) with a slope of 1/4
Nastasia [14]

Answer:

y = 1/4 x - 1/2

Step-by-step explanation:

Remark

The general equation for a line is y = mx + b

You know that m = 1/4. The problem is what do you do about (2,0)?

Solution

y = 1/4 x + b                  Let x = 2 when y = 0

0 = 1/4 * 2 + b               multiply 2 * 1/4

0 = 1/2 + b                     Subtract 1/2 from both sides

b = - 1/2

equation y = 1/4 x - 1/2
