Answer:
51.9
8.9
78.5
8.8
Explanation:
You round up if the number to the right is 5 or greater.
So, apply this to the numbers and the 8 in A rounds up, going to a 51.9.
The 9 does not round up because of the one.
The 5 also does not round up because of the 2.
The 7 does round up because of the 6.
Answer:
x = 2 csc(1) y - π/4
Step-by-step explanation:
Solve for x:
y = 1/2 sin(1) (x + π/4)
y = 1/2 (x + π/4) sin(1) is equivalent to 1/2 (x + π/4) sin(1) = y:
1/2 sin(1) (x + π/4) = y
Divide both sides by sin(1)/2:
x + π/4 = 2 csc(1) y
Subtract π/4 from both sides:
Answer: x = 2 csc(1) y - π/4
