the temperature fell from o degrees to 6 3/5 degrees below 0 in 2 1/5 hours. what was the temperature change per hour?
Kay [80]

<u>Answer:</u>

The temperature change per hour was -3 degrees per hour.

<u>Step-by-step explanation:</u>

We know that the temperature fell from 0 degrees to -6\frac{3}{5} degrees in a time period of 2\frac{1}{5} hours.

So to find the rate of change of the temperature, we will divide the change in temperature by the number of hours.

For that, we will change the mixed number into improper fractions and then solve:

-6\frac{3}{5}=-\frac{33}{5}degrees

2\frac{1}{5}=\frac{11}{5} hours

Temperature change per hour = \frac{-\frac{33}{5}}{\frac{11}{5}} = \frac{33}{5}*-\frac{5}{11}=-3

Therefore, the temperature change per hour was -3 degrees per hour.

What are the roots of 2x^2+4x+7? Use the quadratic formula. Show your work
attashe74 [19]

Answer:

First you must rewrite the given equation in standard form:

2x^2 - 4x + 7 = 0.  Here a=2, b=-4 and c=7.

The solutions are thus 

      -[-4] plus or minus sqrt( [-4]^2 - 4[2][7] )

x = --------------------------------------------------------

                                  4

                  4 plus or minus sqrt (16 - 56)

or:     x = --------------------------------------------

                                       4

16-56 = - 40, a negative number.  Thus, we must introduce the imaginary operator:  sqrt (-40) = 2i*sqrt(10)

The roots are thus:

        4 plus or minus 2i sqrt(10)              2 plus or minus i*sqrt(10)

x = -----------------------------------------  =  ---------------------------------------

                           4                                                        2
