Answer:
Step-by-step explanation:
sin60° =
tan60° =
tan45° = 1
cos45° =
(2sin60°)(3tan60°) - (4tan45°)(2cos45°)
now substitute the values of each trigonometrical angles
One spinner is divided into five equal sections numbered 1 to 5. A second spinner is divided into seven equal sections numbered

Answer: Hence, there are 35 outcomes in total if both the spinners are spun.
Step-by-step explanation:
Since we have given that
Number of outcomes for spinner numbered 1 to 5 = 5
Number of outcomes for spinner numbered 6 to 12 = 7
So, Using the Fundamental theorem of Counting, we get the total number of outcomes when both the spinners are spun together.
So, Number of total outcomes would be
Hence, there are 35 outcomes in total if both the spinners are spun.

First let's talk about the blue line.
You can see its rising so its slope is certainly positive. But by how much is it rising? You can observe that each unit it rises it goes 1 forward and 1 up so its slope is the ratio of 1 up and 1 forward which is just 1.
We have thusly,
Now look at where blue line intercepts y-axis, -1. That is our n.
So the blue line has the equation of,
Next the black lines. The black lines are axes so their equations are a bit different.
First let's deal with x-axis, does it have slope? Yes but it is 0. The x-axis is still, not rising nor falling. Where does x-axis intercept y-axis? At 0. So the equation would be,
Now we have y-axis. Does y axis have a slope? Yes but it is . The y-axis rises infinitely in no run. Where does it intercept y-axis? Everywhere! So what should the equation be? What if we ask where does y-axis intercept x-axis and write its equation in terms of x. Y-axis intercepts x-axis at 0 which means its equation is,
That is, every point of a form lies on y-axis.
