Answer:
the reference angle is given by 
sine = negative
cosine = positive
tangent = negative
Step-by-step explanation:
We have been given the angle 
The angle lies in Quadrant IV. Hence, in order to find the reference angle, we can subtract this angle with 
Therefore, the reference angle is given by
In Quadrant IV, cosine and secant functions are positive and rest trigonometric functions are negative.
Thus, we have
sine = negative
cosine = positive
tangent = negative
10 squared = 100
4 cubed = 16
100-16 =84
Answer:
44.4%
Step-by-step explanation:
The probability in this case would be the specific number of pairs of means that we are asked to calculate, that is, blue divided by the total number of pairs, which would be the sum of the different colors, then:
We have that blue there are 4 pairs, and in total it would be 2 + 4 + 3 = 9, that is to say 9 pairs of means.
therefore the probability is:
4/9 = 0.444
Which means that there is a 44.4% chance of drawing a blue pair.
The Volume of the cube is 40 Cm3
