(a^3-2a^2)-(3a^2-4a^3)
(a^3-2a^2)-3a^2+4a^3
5a^3-5a^2
The answer of this question is going to be B then on 2 A then D
Answer: That would be demonstrated as 3/14, or 3 over 14
Step-by-step explanation:
The numerator is the number being divided, and the denominator is the divider. So if I were to write 1/2, 1 is being divided by 2, which results with .50. .50 is half of the whole number 1, make sense? :)
7x if you add the numbers and just keep the x the same
You can draw a diagram of the situation, representing it by a right triuangle.
In the right triangle the hypotenuse is the distance indicated by the radio signal, 1503 m, and the angle is 41°.
The opposed leg to 41° is the height of the ballon.
Then you can use the sine trigonometric function.
sine (41°) = opposed leg / hypotenuse = x / 1503 m => x = 1503m * sine(41°)
=> x = 986m.
Answer: 986m
