If 20% of a number p is 10, what is 10% of p?
kobusy [5.1K]

Answer:

5

Step-by-step explanation:

20% of p = 10

20% = 0.2

Multiply

0.2p = 10

Multiply both sides of the equation by 5

p = 50

Find 10% of p

10% = 0.1

Multiply

0.1(50)

5

10% of p is 5

Hope this helps :)

What is 2x^2+9x-18 in vertex form?
atroni [7]

Complete the square:

2<em>x</em>² + 9<em>x</em> - 18

2(<em>x</em>² + 9/2 <em>x</em>) - 18

2(<em>x</em>² + 9/2 <em>x</em> + 81/16 - 81/16) - 18

2(<em>x</em>² + 2 (9/4) <em>x</em> + (9/4)²) - 81/8 - 18

2(<em>x</em> + 9/4)² - 225/8

If you're not familiar with the method, the idea is to get a quadratic from the standard form

<em>ax</em>² + <em>bx</em> + <em>c</em>

into its vertex form

<em>a</em> (<em>x</em> - <em>h</em>)² + <em>k</em>

where (<em>h</em>, <em>k</em>) is the vertex of the parabola associated with the quadratic.

Expand the vertex form to get

<em>a</em> (<em>x</em>² - 2<em>xh</em> + <em>h</em>²) + <em>k</em>

<em>ax</em>² - 2<em>ahx</em> + <em>ah</em>² + <em>k</em>

For the two forms to be equivalent, we must have

-2<em>ah</em> = <em>b</em>

<em>ah</em>² + <em>k</em> = <em>c</em>

which means

<em>h</em> = -<em>b</em>/(2<em>a</em>)

<em>k</em> = <em>c</em> - <em>ah</em>² = <em>c</em> - <em>b</em>²/(4<em>a</em>)

In this case, <em>a</em> = 2, <em>b</em> = 9, and <em>c</em> = -18, so

<em>h</em> = -9/(2 • 2) = -9/4

<em>k</em> = 18 - 9²/(4 • 2) = -225/8
