Answer:

Step-by-step explanation:

X( -9 , 2)  & Y(5 , -4)

distance = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\XY=\sqrt{(5-[-9])^{2}+(-4-2)^{2}}\\\\=\sqrt{(5+9)^{2}+(-6)^{2}}\\\\=\sqrt{(14)^{2}+(-6)^{2}}\\\\=\sqrt{196+36}\\\\=\sqrt{232}\\\\= 15.23

What is the range of f(x) = – 4?
Andre45 [30]
The answer is -4. The range is the y-value and when you  say f(x) that is the same thing as y, so if f(x) = -4 that means y = -4 which means the range is -4.

S+T+U=180°{sum of angle of triangle}

  • 68°+90°+U=180°
  • U=180-158°
  • U=22°

sin theta= p/h

sin22°=x/83

o.37=x/83

x=0.37×83

x=30.71

a cone with radius of 3 feet and a height of 5 feet is placed on top of a cylinder as shown find the volume of the total figure
Darina [25.2K]

Answer: Volume of the cone = 47.12 cubic feet.

Step-by-step explanation:

You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.

To solve for the full volume including the cylinder, use the cylinder's volume formula.

Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.

Volume of a cone is pi(r^2)(h/3)

plug and chug!

h stands for height and r stands for radius.
