10x + 2y = -2
2y = -10x -2
y = -5x - 1 (slope is -5 and a parallel line will have the same slope)
y = mx + b
slope(m) = -5
12 = -5(0) + b
12 = 0 + b
12 = b
so the parallel line is y = -5x + 12
hope this helps, God bless!
Answer: 5.97 hours
Step-by-step explanation:
S(t) = 100
I put in 100 = 600 x e^-0.3t and it came out to be 5.97 when rounded to the nearest hundredth. It is also correct on khan academy.
Answer: option c.
Step-by-step explanation:
You need to remember the identity:

The inverse of the tangent function is arctangent. You need to use this to calculate the angle "R":
You know that you need to find the measure of "R" and
(which is the opposite side) and
(which is the adjacent side), you can sustitute values into 
Then, you get:
