Answer: 0.75
Step-by-step explanation:
We can do this by drawing a terminal side in a standard position and then drawing the associated triangle. We then use the Pythagoras theorem to find the missing side the hypotenuse. Then, this will give a Pythagorean Triplet of 3, 4 and 5.
We now have a triangle with the values of:
x = 4
y =3
h^2= 4^2 + 3^2
h^2 = 16 + 9
h^2 = 25
h = 5
h = 5
Tangent = opposite/adjacent
= y/x
= 3/4
= 0.75
You need to add both numbers and then that's your answer 6-6/12
Answer: y => 12
y is greater than or equal to 12
Step-by-step explanation:
So they give you the function of y = 2x + 4 and the domain of all real numbers is greater than or equal to 4.
In simple term, the domain is x => 4, x is greater than or equal to 4.
Using that we can substitute the x in the function by 4.
y = 2(4) + 4
y = 8 + 4
Which gave us the answer of 12.
Since the domain can be anything greater than 4 or 4. We can expect the
same for the range.
Then the range will be 12 or greater than 12. For example, 13, 14, 15, 16...
Ex. y = 2(5) + 4
y = 10 + 4
y = 14
Ex. y = 2(4.5) + 4
y = 9 + 4
y = 13
The third answer has a y-intercept of 4.
