Answer:
The solutions are π/4, 3π/4,5π/4,7π/4
Step-by-step explanation:
The given equation is
6sin²(x) = 3
Divide by 6 to get:
This implies that;
If
in the first quadrant
in the second quadrant.
If
in the third quadrant
If the satellite moves at a speed of 27,000 km p/h, your answer depends on the question.
This could be written in an algebraic expression, such as:
27,000x = S [for S stands for the ultimate speed of the satellite]
Of course, if this is a 3rd grade level question, I highly doubt they have even gotten started to including the alphabet into math.
So, I would suggest plugging 4 into X.
To explain this to her, just say that the speed needs to be multiplied by the amount of hours it has traveled. (I got 4 because there is a '4' in the question instead of 'for').
Meaning,
27,000 x 4 = 108,000 km per 4 hours
If her teacher decides to ask why that number, have her explain the question did not make sense so she plugged in a 4 to find an answer to a certain amount of hours.
Hope that helps a bit with the confusion!
Let A and B be the mL of each solution needed.
quantity equation
A + B = 360
concentration equation
0.5A + 0.6B = 0.53(360)
use A = 360 - B for substitution in the other equation.
0.5(360 - B) + 0.6B = 190.8
180 - 0.5B + 0.6B = 190.8
180 + 0.1B = 190.8
0.1B = 190.8 - 180
0.1B = 10.8
B = 10.8/0.1
B = 108 mL
then A+B = 360
A + 108 = 360
A = 360 - 108
A = 252 mL
