How can you use the graph to f he amount of distilled water to use for 4.5 milliliters of ammonia?
Elden [556K]

Answer:

The graph can show you how much distilled water for 4 milliliters of ammonia and 5 milliliters of ammonia. You can use the graph to find 4.5 by find the midpoint of two amounts of distilled water. Such as, say that 4 milliliters of ammonia = 200 distilled water and 5 milliliters of ammonia=  250 distilled water. Then the answer to 4.5 milliliters of ammonia is 225 distilled water.

A cosine function has a period of 4, a maximum value of 20, and a minimum value of 0. The function is a not a reflection of its
3241004551 [841]

Answer:

Step-by-step explanation:

You'll need to find a way to share the graph or graphs associated with this problem.

The period is 4.  The relationship between period and b (the coefficient of the independent variable of the cosine function) is (period) =(2π.b).  Given that the period here is 4,

       2π                          2π

4 = ---------, and so b = ------- = π/2.

                                       4

So now our y  = a*cos (bx + c) becomes

                    π

y = 10*cos (------x + 0 + 10

                     2

The horizontal center line of this cosine curve is y = 10.  The maximum value of the curve is 20, which is 10 + 10, and the minimum value is 0, which is 10 - 10.
