81.
Add them all and then divide by the number of days (by 5)
Answer:

Step-by-step explanation:
Given the expression
, we will use laws of indices to get the equivalent expression as shown below;
According to one of the law of indices,


This gives the required expression
1 pound=16ouncees
1ounce =28 grams aprox
so 5 pounds times 16=80 ounces
80 ounces times 28=2240 grams aprox
Answer:
1) - 2 / (cos x + sinx)^2.
Step-by-step explanation:
1) I assume you want the derivative of (cos x - sin x) / ( cos x + sin x).
y' = (cosx + sinx)( -sinx - cosx) - (cosx - sinx)(-sinx + cosx)
---------------------------------------------------------------------------
(cosx + sinx)^2
= -sinxcosx - cos^2x - sin^2x - sinxcosx - (-sinxcosx+cos^2x+sin^2x-sinxcosx
-------------------------------------------------------------------------------------------------------
(cosx + sinx)^2
= -2sinxcosx - 1 - ( -2sinxcosx + 1 ) / (cosx + sinx)^2
= -2sinxcosx - 1 - ( -2sinxcosx + 1 ) / (cosx + sinx)^2
= - 2 / (cos x + sinx)^2.
Answer:

General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations using graphing
Step-by-step explanation:
To find the solution set of a systems of equations, the point where the 2 lines intersect would show the solution for the systems.
According to the graph given, both lines intersect each other at x = -1.
Therefore, our answer is B.
