Let and be the respective radii of balloons A and B. If the fixed total volume is V, then
and knowing and at the start, we have V = 6916π/3 cm³. Then when , the radius of the other sphere is .
Differentiating both sides with respect to time t gives a relation between the rates of change of the radii:
We're given the whole time. At the moment , the radius of balloon B is changing at a rate of
Answer:
x=12
Step-by-step explanation:
The two angles shown are complementary angles, so the add to 90 degrees
x+42 + 3x = 90
Combine like terms
4x+42 = 90
Subtract 42 from each side
4x+42-42 = 90-42
4x = 48
Divide by 4
4x/4 = 48/4
x = 12
The ones in the bracket are a similar way of vectors.
hope that kinndaaa helps sorry xoxo
