Answer:
336 and 448
Step-by-step explanation:
sum the ratio
divide the actual number by the sum i.e 784÷7=122
multiply 112 by 3 and by 4
Answer:
12/13
Step-by-step explanation:
The length of the segment from the origin to the terminal point is ...
r = √((-5)² +12²) = √169 = 13
The sine of the angle is the ratio of the y-coordinate to this distance
sin(θ) = y/r = 12/13
_____
Additional comment
The other trig functions are ...
cos(θ) = x/r = -5/13
tan(θ) = y/x = -12/5
This is a 2nd-quadrant angle, where the sine is positive, but the cosine and tangent are negative.
Answer: the square root of 30 is simplified to 5...
Hope this helps! :D
Step-by-step explanation:
Hope this helps, I did it on paper that way it would be easier to show my work.
Percent error = |actual error - expected error/ expected error| * 100%
(|75-95|)/95 = 0.21
0.21 * 100% = 21% error
