Vivian is solving the equation 0=x2−5x−4 0 = x 2 − 5 x − 4 using the quadratic formula. Which value is the negative real number

Aleks [24]

<h3>answer:</h3>

-0.7

<h3>steps:</h3>

the quadratic formula is

$\frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a}$

substitute the correct values in

$\frac{ - ( - 5) + - \sqrt{ {( - 5)}^{2} - 4(1)( - 4) } }{2(1)}$

where it says +- you would type this into your calculator with + AND THEN - to get two separate answers.

when you type + you get the answer of: 5.701562119...

when you type - you get the answer of:

-0.7015621187...

when you round to the nearest tenth you get -0.7

hope this helps! :)

How may weeks are there in a year?

Zanzabum

Answer:

There are exactly 52.142857142857 weeks in the year 2019. This is equivalent to 52 weeks and 1 extra day, since there are 365 total days in 2019. Most years have 365 days, but a leap year has 366 days. That adds up to 52 weeks (where each week is exactly 7 days) PLUS 1 or 2 additional days.There are 52 complete weeks in a year. The year has 365 days, leaving one extra day. A leap year has 366 days, adding a second extra day. This makes 52 1/7 weeks in a normal year and 52 2/7 weeks in a leap year..
