Answer:
She will earn 150$
Step-by-step explanation:
4% = 0.04
0.04 x $625 = 25
Now we divide 25 by the number of years, which is 6.
6 x 25 = 150$
Therefore, Skye earns 150$ from interest over the course of 6 years.
M = Mo - 20 * Weeks = 300 - 20 * 6 = 180 $
Answer:
65 coins
Step-by-step explanation:
Set this problem up with a porportion.
After that, cross multiple and divide.
25 times 260. Then divide by 100. That is then your answer.
2cos2x=y
dy/dx(2cos2x)=-4sin2x
d/du cosu= u'×cos'u=-u'×sinu
d/du sinu= u'×sin'u= u'×cosu
d/du tanu = u'×(1+tan²u)
d/du cotu = u'×-(1+cot²u)
proof for cosu :
cos2x= 1-2sin²x
or 2cosx²-1
or cos²x-sin²x
we will one of this fro example let's take the first one
d/dx 1-2sin²x=0-2×2(sinx)×cosx=-2sin2x
and we have 2 in the begining so its -4sin2x
