Answer:
A 61
Step-by-step explanation:
Cos A = 0.4848
A = cos ^-1(0.4848)
A = 61

Answer: Choice C</h3>
For choices A, B and D, the x values repeat in some way.
Choice A has x = 2 repeated
Choice B has x = 10 repeated
Choice D has x = 13 repeated
A function cannot have repeated x values. Put another way, a function is only possible if any given x input goes to exactly one y output.
Choice C shows each x value listed once only. If you were to graph these points, then the relation will pass the vertical line test.
Answer:
Step-by-step explanation:
Cosine (cos) is adjacent by hypotenuse.
In any of the 45° angles, 1 is adjacent and √2 is the hypotenuse.
So arrange them to get
Y = 2x + 3
First, find the y-intercept (b). This is where the line meets the y-axis. The line meets the y-axis at 3, so the y-intercept is 3.
Now, find the slope (m) of the line. Slope is rise divided by run. The line goes up by 2, over by 1, up by 2, over by 1, and so on. So, the rise is 2 and the run is 1. 2 divided by 1 is 2, so the slope is 2.
Put these together into the equation to get y = 2x + 3.
