Answer:
the domain is equal to all real numbers greater than or equal to 0
Step-by-step explanation:
The domain is all the numbers in which the graph reaches in regards to the x axis
We can see from the graph that it starts at 0 and then moves right
THis means that the domain is equal to all real numbers greater than or equal to 0

Answer: Choice D
(0,-4) (4,0) and (-1,-5)
===========================================================
Explanation:
Plug in x = -4
y = x-4
y = -4-4
y = -8
The point (-4,-8) is on the line instead of (-4,0). This rules out choice A and choice B.
Now plug in x = 1
y = x-4
y = 1-4
y = -3
We get (1,-3) instead of (1,5). So we can rule out choice C.
The answer must be choice D.
The graph is below.
Answer:
The answer is 7(tan 50°)
Step-by-step explanation:
So first you need to find which formula you will be using to do this you need to find if you're talking about the hypotenuse, opposite, or adjacent.
The side that measures 7 meters would be the adjacent because its right next to the angle and its not the hypotenuse because its not the largest side
The side which we do not know the length to will be the opposite side because it is opposite from where the angle is.
There are 3 formulas:
sin A = Opposite side/Hypotenuse = BC/AB
cos A = Adjacent side/Hypotenuse = AC/AB
tan A = Opposite side/Adjacent side = BC/AC
There is one formula that has Opposite and Adjacent which is tangent so thats the formula you'll use
Next you plug in the values that you have so your formula will look like this:
Tan 50° = x/7
A will always be where you plug in the angle and then you plug in the information according to what side it is
Every time that x is the numerator you will just multiply both sides by the denominator which gives you:
7(tan 50°)
Which is your answer :))
Answer:
2.5 is closer to 0
Step-by-step explanation:
when using 2.5 you have to round down and if you round down you get 0 not 5.
