Well you want to do 7.8 divided by 2 which is 3.9. Then you add that to 7.8 to signify that is it 1 1/2 which is 11.7. You subtract that from 60 and you get 48.3 and that is your answer
Answer:
x=-5/2+-√33/2
Step-by-step explanation:
x^2+5x=2
you then solve by completing the square using the formula (b/2)^2 in order to create the new term. Solve for x by using this term to complete the square.
Your answer is then
x=-5/2+-√33/2
Answer:
none of the above
Step-by-step explanation:
All of the answer choices agree that the magnitude of the components is 150/√2 ≈ 106.1. The units of these components should be "mph", the same as the units of the magnitude of the given vector.
We only know the angle with respect to horizontal. We don't know whether that angle is measured with respect to the positive x-axis or the negative x-axis. Both of those are horizontal, and there is nothing in the problem statement that restricts the airplane to be traveling in one direction or the other.
Possible answers are ...
<106.1 mph, -106.1 mph> . . . . . . "horizontal" is +x direction
<-106.1 mph, -106.1 mph> . . . . . "horizontal" is -x direction
(The units are not degrees (°).)
Total half lives (n) = 25/10=2.5T
Ending amount= Beganing amount/2^n
= 800/2^2.5
= 141.41g
