Answer:

315.19

Step-by-step explanation:

Given:

  • <u>Radius</u> of the <em>cone </em>is 7.
  • <u>Height</u> of the<em> cone</em>  is 7.

To find:

The volume of a<em> cone</em> with a <u>radius</u> of <em>7</em> and a <u>height</u> of <em>7</em>.

Solution:

<em>Use the formula:</em><em> </em>V=\frac{1}{3}h\pi r^2

Result:

V=\pi r^2\frac{h}{3}

=\pi *7^2*\frac{7}{3}

≈359.18876

Now round to the nearest hundredth.

≈ 359.19

Note*

Nearest hundredth is the second digit after the decimal point.

If y varies directly as x, and y is 18 when x is 5, which expression can be used to find the value of y when x is 11?
Leokris [45]

Answer: The value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6

Step-by-step explanation:

Since we have given that

y varies directly as x.

If y = 18, when x = 5.

So, we need to find the value of y when x is 11.

According to question, we get that

\dfrac{y}{x}=\dfrac{18}{5}=\dfrac{y}{11}\\\\18\times 11=5y\\\\198=5y\\\\\dfrac{198}{5}=y\\\\y=39.6

Hence, the value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6

Solve x2 - 8x = 20 by completing the square. Which is the solution set of the equation?
Artyom0805 [142]

Answer:

{-2,10}

Step-by-step explanation:

x^2 - 8x = 20

Take the coefficient of x

-8

Divide by 2

-8/2 =-4

Square it

(-4)^2 =16

Add this to each side

x^2 - 8x+16 = 20+16

x^2 - 8x+16 = 36

The left hand side becomes( x + (-8/2) )^2

(x - 4)^2 = 36

Take the square root of each side

sqrt((x - 4)^2) =±sqrt( 36)

x-4 = ±6

Add 4 to each side

x-4+4 = 4±6

x = 4±6

x = 4+6       x = 4-6

x = 10        x = -2
