Given the graph below, find MN. Round to the nearest hundredth.
Galina-37 [17]

Answer:

5.39

Step-by-step explanation:

if you are trying to find MN then it means you need to find the length.

we cant use slope, but we CAN make it a triangle!

*see the attached image*

we can use A^2+B^2 to get what the hypotenuse is or C^2 is

2^2+5^2

4+25=29

the square root of 29 is 5.385

then we just round to the hundreth!

5.39

(8>5, so we bump him up)

hope this helped!

-3/8 x (-12/5)=
zimovet [89]

Answer:

D.) 9/10

Step-by-step explanation:

We want to simplify: -\frac{3}{8}\times \frac{-12}{5}

4 divides 8 twice and 12 three times.

\implies -\frac{3}{8}\times \frac{-12}{5}=-\frac{3}{2}\times \frac{-3}{5}

We multiply the first numerator by the second and the first denominator by the second.

This will give us:

\implies -\frac{3}{8}\times \frac{-12}{5}=\frac{9}{10}

Therefore the last choice is correct.

Set the quadratic = to 0 and solve for time, t:

-16t^2 - 8t + 20 = 0

Reduce this to:

-4t^2 - 2t + 5 = 0

 Here a= -4, b= -2 and c =5.  Then,

       2 plus or minus sqrt( 4-4(-4)(5) )
t = ---------------------------------------------
                            -8
        2 plus or minus sqrt(84)
  = ------------------------------------
                          -8

Finish evaluating this.  If either outcome is negative, discard it.
The result will be the number of seconds required for the ball to hit the grnd.
