Answer:
Step-by-step explanation:
Given
1 bag = 4 doughnuts
1 carton = 10 doughnuts
Required
Determine the amount of doughnuts in b bags and c cartons
If 1 bag contains 4 doughnuts, then b bags contain 4b doughnuts
If 1 carton contains 10 doughnuts, then c cartons contain 10b doughnuts
So, the total (t) is calculated by adding up the amount of doughnuts in the cartons and the bags:
i.e.
Answer: a) A = 3
b) P = 4
c)
<u>Step-by-step explanation:</u>
Period (P) is the reciprocal of the frequency (f)
f = → P =
y = A cos (Bx - C) + D
- A = 3
- → → 4B = 2π → →
- C = none given
- D = none given
Answer:
6/10
Step-by-step explanation:
all can be reduced to 2/5, except 6/10:
2/5
8/20=2/5 (divide out 4)
12/30=2/5 (divide out 6)
but not
6/10 = 3/5!
Answer:
Step-by-step explanation:
Your answer is 9.
53 x 2 = 106
106 + 20 = 126
126 / 14 = 9 !
Using the product rule
xCos(y)dy/dx + sin(y) + ycos(x)+sin(x)dy/dx = 0
xcosydy/dx + sin(x)dy/dx = -sin(y) - ycos(x)
(xcos(y) + sin(x))dy/dx = -sin(y) - ycos(x)
dy/dx = [-sin(y) - ycos(x)]/ {xcos(y) + sin(x)}
