Answer:
2.8 i think
Step-by-step explanation:
You first divide 40 by 19:
19/40=?
Then you convert that to percentage by dropping the decimal point and attaching a %
(hint: you should get 48% about :)
Answer:
5) we get a=6
6) we get c=8
Step-by-step explanation:
The triangles given are similar.
When the triangles are similar, the ratio of corresponding sides are also similar.
5) If c = 12, find a
We will use the ratio

Now cross multiply to find value of a

So, we get a=6
6. If b = 6.4, find c
We will use the ratio

Now cross multiply to find value of b

So, we get c=8



so if you notice yours

now.. normally the function

has a D value of 0, or no vertical shift, and the amplitude and the period simply make the wave taller and thinner, but the midline is still the x-axis
now, with D = 6.1, that moves the midline up vertically that much
now.. the period, well, B = 5/3, normal period of cosine is

so, the new period will be

notice the picture below
the vertical shift by the D component, or 6.1, moved the midline to y = 6.1 :)
