<u>Given </u><u>:</u><u>-</u><u> </u>

  • C is the midpoint of BD .
  • BC = x + 7
  • CD = 8x

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • Value of BD ( correct )

<u>Answer</u><u> </u><u>:</u><u>-</u><u> </u>

As C is the midpoint , we can say that the line is BCD . So that ,

  • BC + CD = BD

Substitute the values ,

  • ( x+7 ) + 8x = BD
  • BD = x + 8x + 7
  • BD = 9x + 7 .

<u>Hence</u><u> the</u><u> </u><u>value</u><u> of</u><u> </u><u>BD </u><u>is </u><u>9</u><u>x</u><u> </u><u>+</u><u> </u><u>7</u><u> </u><u>.</u>

The volume of a cone is 3πx3 cubic units and its height is x units.
GaryK [48]

Answer:

It is given that the volume of a cone = 3 \pi x^{3} cubic units

Volume of cone with radius 'r' and height 'h' = \frac{1}{3} \pi r^{2}h

Equating the given volumes, we get

3 \pi x^{3}=\frac{1}{3} \pi r^{2}h

r^{2} h =3 \times 3 x^{3}

r^{2} h =9 x^{3}

It is given that the height is 'x' units.

Therefore, r^{2} x =9 x^{3}

r^{2} =9 x^{2}

Therefore, r = 3x

So, the expression '3x' represents the radius of the cone's base in units.

If you have a slopeof 5/8 and goes through the point (8,2) what is the formula and how do you get it?
IgorC [24]
--------------------------
Slope :
--------------------------
Slope = 5/8

--------------------------
Equation: 
--------------------------
y = 5/8 x + b

--------------------------
Find y-intercept :
--------------------------
At (8, 2), 
2 = 5/8 (8) + b
2 = 5 + b
b = 2 - 5
b = -3

--------------------------
Equation :
--------------------------
y = 5/8x - 3

-----------------------------------------------------------------
Answer: y = 5/8 x - 3
