Answer:
A
Step-by-step explanation:
In this function, the domain, or the x value, has no limits. You can substitue any value of x into (x^2-4) and any result is valid.
I hope this helped!
Answer:
x = the price of one coffee mug.
n = number of coffee mugs sold
115.50 = x × n
n = 115.50÷ x
you cant solve it without additional informations.
You can first use the fundamental trigonometric identity:
sin(x) ^2 + cos(x) ^2 = 1
=> cos(x) ^2 = 1 - sin(x) ^2
=> cos(x) ^2 = 1 - (-4/5)^2 = 1 - 16/25 = (25 - 16) / 25 = 9 /25
=> cos (x) = +/ - √ (9/25) = +/- 3/5
Now, analyze the sign.
In the fhird quadrant the cosine is negative, so the answer is cos(x) = - 3/5.
