Answer:
5^2=25 5x5
5^-2=.04 The reciprocal of 5 is 1/5 ^2 means that 1/5 x2 = 2/5 or .4
(-5)^2=25 -5*-5
-5^2=-25 -(5*5)
Answer:
75 minutes
Step-by-step explanation:
First cook 40 and 45 min dishes on separate burners. Then after 40 min put 35 min dish to be cooked on that burner. This will take 75 minutes time.
On second burner put firstly 15 min and then 10 min dish or vice versa as it doesn't matter. This second burner will take 70 minutes which is less then first one.
Answer:
Fourth option
Step-by-step explanation:
When graphing the given inequalities you will get a region like the one shown in the attached image. This region is delimited by 4 straight

The points indicated at the ends of the region are the maximum possible values of x and y.
We must test these points in the objective function
and see which point maximizes the value of P.
<em><u>Remember that the boundaries of the region are not included.
</u></em>
We can prove the point <em>x = 0</em> and <em>y = 39</em> because (0,4) is not included in the region.

Now we test the point <em>x = 33</em> and <em>y = 16
</em>

Now we test the point <em>x = 44</em> and <em>y = 0</em>

Finally the optimal value is:
<em>x = 33 oz</em>
<em>y = 16 oz
</em>
