What constant do you need to add to each quadratic to complete the square?

babunello [35]

Answer:

1. 4

2. 16

3. 9

Step-by-step explanation:

Completing the square requires a quadratic in $ax^2+bx=c$ form. Once in this form, calculate $(\frac{b}{2})^2$ .

1. $(\frac{b}{2})^2=(\frac{-4}{2})^2=4$

2. $(\frac{b}{2})^2=(\frac{-8}{2})^2=16$

3. Requires you divide everything by 3 first.

$\frac{3x^2+18x}{3} =\frac{249}{3} \\x^2+6x=81$

$(\frac{b}{2})^2=(\frac{6}{2})^2=9$

0.145 as a fraction or a mixed number.

Vlad1618 [11]

we can convert any decimal to a fraction, by simply <u>using as many zeros at the bottom as there are decimals, and losing the dot atop</u>, now let's do so, notice we have 3 decimals, so we'll use 3 zeros.

$\bf 0.\underline{145}\implies \cfrac{0145}{1\underline{000}}\implies \stackrel{simplified}{\cfrac{29}{200}}$

The probability of Jamie making money investing in bonds is 1/20. The probability of Jamie making money investing in stocks is 8

lidiya [134]

One interpretation of this problem would be:

The prob. that Jamie both makes money in both bonds and stocks is

(1/20)(0.82), approximately. That comes out to 0.041. This is true onlyl if the two given events are completely independent, which is most likely not the case, because simiilar business climates affect both stocks and bonds.
