QUESTION A.
m (Micah's savings) 5 10 15 20
p (Parents') 10 20 30 40
p = 2m
QUESTION B.
p = 2X150
p = $300
Since we don't have a figure we'll assume one of them is right and we're just being asked to check if they're the same number. I like writing polar coordinates with a P in front to remind me.
It's surely false if that's really a 3π/7; I'll guess that's a typo that's really 3π/4.
P(6√2, 7π/4) = ( 6√2 cos 7π/4, 6√2 sin 7π/4 )
P(-6√2, 3π/4) = ( -6√2 cos 3π/4, -6√2 sin 3π/4 )
That's true since when we add pi to an angle it negates both the sine and the cosine,
cos(7π/4) = cos(π + 3π/4) = -cos(3π/4)
sin(7π/4) = sin(π + 3π/4) = -sin(3π/4)
Answer: TRUE
Answer:
143 calories
Step-by-step explanation:
We can use a ratio to solve
110 calories x calories
----------------- = ---------------
28.4 grams 36.92 grams
Using cross products
110* 36.92 = 28.4 * x
Divide each side by 28.4
110*36.92 / 28.4 = x
143 calories = x
