Step-by-step explanation:
cos(90) = 0
around this point the cos function "mirrors" with opposite signs. cos(<90) is positive and cos(>90) is negative.
but |cos(90-a)| = |cos(90+a)| for 0 <= a <= 90
75 = 90 - 15
105 = 90 + 15
so, a = 15
and because of
|cos(90-a)| = |cos(90+a)| for 0 <= a <= 90
cos (90-15) = cos(75) = -cos(90+15) = -cos(105)
Answer:

Step-by-step explanation:
There are 6 sides on dice, therefore the sample space would be 6 (<em>the</em><em> </em><em>sample</em><em> </em><em>space</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>denominator</em>). We were asked to find the probability of getting a 1 or a 6. Since we were given 2 options 1 or 6, it therefore means that we are trying to find the probability of the dice rolling on 2 out of the 6 sides it has. Therefore the probability would be:

A third as a decimal is

Divide 48 by 4 and you get 12 ounces. Therefore, each 1/4 of a bucket is equal to 12 ounces. divide 48 by 3 and you get 16 ounces. Therefore, each 1/3 of a bucket is 16 ounces. Divide 48 by 6 and you get 8 ounces. 8 multiplyed by 5 is 40. Add 40 16 and 12 and you get 68 ounces
The answer to your question is y = sin(x + 90) as we have a sine graph phase shifted 90 units left
Y=1/2x-2
Since y is 2 less than half of x, you subtract to from 1/2x to equal y.
