Track A takes 20 minutes
Track B takes 15 minutes
In 1 minute track be will do a fraction of 1/20, while track B will do 1/15
Both tracks in a minute = 1/20+1/15
                                      = 35/300
Therefore the two tracks will take 300/35 minutes to fill the 200 cubic feet
That is 300/35
           = 8.57  minutes
           ≈ 9 minutes

Find all values of c such that the domain of the following function is the set of all real numbers
Semenov [28]

Answer:

-\sqrt{14} < c < \sqrt{14}

Step-by-step explanation:

For the function to have a domain of all reals, the denominator cannot have a value of zero. x^2 + 2cx + 14 will not have zero as a root if it has no real solutions. A quadratic equation has no solutions when the discriminant is negative.

b^2 - 4ac < 0

(2c)^2 - 4(1)(14) < 0

4c^2 - 56 < 0

4c^2 < 56

c^2 < 14

-\sqrt{14} < c < \sqrt{14}

If Michael and Imani add an 18% tip to 27.32, what does their lunch cost in total?
Otrada [13]
.18 * 27.32 = 4.9176
18% of 27.32 = 4.91

4.91 + 27.32 = 32.23

If Michael and Imani add an 18% tip to 27.32, their lunch cost will be $32.23 in total. 


Hope this helps you! (:
