Bond [772]

Answer:

Coach's friend jog 8.6 miles.

Step-by-step explanation:

Given:

A coach jogs 1.8 miles on Monday, 1.3 miles on Tuesday, and 1.2 miles on Wednesday.

If the coach's friend jogs twice as far as the coach.

Now, to find the miles the coach's friend jog.

Coach jogs on Monday = 1.8 miles.

Coach jogs on Tuesday = 1.3 miles.

Coach jogs on Wednesday = 1.2 miles.

Total miles coach jog = $1.8+1.3+1.2=4.3\ miles.$

As, coach's friend jogs twice as coach.

So, to get the miles coach's friend jogs multiply total miles coach jog by 2 we get:

$Total\ miles\ coach\ jog\times 2$

$4.3\times 2\\\\=8.6\ miles.$

Therefore, coach's friend jog 8.6 miles.

Let 3x^2+kx+4. determine all values of k such that the quadratic equation f(x) =0 has one real root

user100 [1]

//I'll use the discriminant rule for this.
b^2 - 4ac = 0 when one real root

Therefore, k^2 - 4*3*4= 0
k^2 = 48
k= +-4√3

9/14 / 5/12 simplify this fraction

nignag [31]

I'm assuming those are two fractions being divided. I just write it out. It looks scary but it's really not. Just do this:
~=this is my dividing sign when not in fraction form cause I don't have an actual sign here.

9/14 ~ 5/12

Then you KCF(Keep, Change, Flip). Keep the first number the same. Change the dividing sign to multiplication. Then flip the last fraction so that it is now 12/5.
The problem now stands as:

9/14 • 12/5

Simplify and the you have your final answer. I recommend looking up the keep change flip video by flocabulary in case you haven't checked it out yet. It really helped me learn this method. Hope this helped!!
