The cosine ratio is the side adjacent to the reference angle over the hypotenuse. Angle T has a side opposite of length 68, and the hypotenuse is 85. Therefore, the cosine of T is 68/85. That gives us a decimal of .8. It's very important that the ratio of sin and cos are decimals less than 1 but greater than 0. If you try to take the inverse cosine of, say, 1.4 on your calculator you will get an error message. That's because sin and cos oscillate between 1 and -1 on the graph and do not exist higher or lower than that.
Answer:
31.85
Step-by-step explanation:
<em>Hey there!</em>
Well to simplify the given expression we do,
-6.5 * -4.9
= 31.85

Answer:
-37.5 m
Step-by-step explanation:
If we assume that "one full day" is 24 hours, then 15 hours represents the fraction 15/24 of a day. Since the drilling rate was constant, and was presumed to start from a height of 0, the height after 15 hours is that fraction of the day's work:
... (15/24)×(-60 m) = -37.5 m
Answer:
maybe the second?
Step-by-step explanation:
y = (3x)/2 + 2
Slope = 3/2
y-intercept = 2
The first point is y-intercept when x = 0 = (0,2). Now according to our slope we move 3 up (Why up? Because it's positive) and 2 right (Why right? Because it's positive).
When you move 3 up from (0,2), you get (0,5) and move 2 right which is (2,5).
Remember: slope = change in y / change in x
Points: (0,2) and (2,5)
