Answer:

First choice:

         \large\boxed{\large\boxed{h=\frac{3V}{784\pi};21cm}}

Explanation:

<em><u>1. Formula for the volume of a cone</u></em><u> (given)</u>

<em><u /></em>

      V=\frac{1}{3} (28^2)\pi h

<em><u>2. Identify the inverse of this function</u></em>

Solve for h:

       3V=(28)^2\pi h\\ \\ \frac{3V}{(28)^2\pi}=h\\\\h=\frac{3V}{(28)^2\pi}\\\\h=\frac{3V}{784\pi}

<em><u>3. Find the height of the cone, if its volume is 5488πcm³</u></em>

Subsititue V with 5488π

          h=\frac{3(5488\pi cm^3)}{784\pi cm^2}\\\\h=21cm

The equation for the line of reflection is x = 2. 
If you drew a vertical line crossing the x-axis on x = 2, the drawing will be the same on the left and right side, as if one side was drawn then exactly copied on the other side but flipped. 
The figure is symmetrical, and x = 2 is the line of symmetry. 
Hope this helps!

If five times the successor of a number is added to an original number the sum is 83
Alexus [3.1K]

Answer:

Let the original number be x

Successor is defined as the number which comes immediately after a particular number.

also, the  successor of a whole number is the number obtained by adding 1 to that number.

Then, the successor of a number x is, x+1

As per the given condition :

we have;

5(x+1)+x =83

Using distributive property on LHS (i.e, a\cdot(b+c)=a\cdot b+a\cdot c )

Then, we have

5x+5+x=83

Combine like terms;

6x+5=83

Subtract 5 from both the sides we get;

6x+5-5=83-5

Simplify:

6x=78

Divide both side by 6,

\frac{6x}{6} =\frac{78}{6}

Simplify:

x =13

Therefore, the original number x is, 13
