Answer:
The relation is discrete function
Domain is {x|x = 2,2,2}
Range is {y|y = 4, -1, -3}
Step-by-step explanation:
I. This function is discrete because x = 2,2,2
and y = 4, -1, -3
Or (2,4), (2,-1) and (2,-3)
If this function is continuous, the x and y will be something like this -3 <= x <= 3
II. Domain is x.value
III. Range is y.value
Ask me for anything.
Answer:
They paid $67.45 altogether.
Step-by-step explanation:
First off, we need to set up the problem, I like to do percentage problems like this:
x/58.65 = 15/100
Cross Multiply
100x=58.65x15
When you multiply 58.65 and 15 you get 879.75
Divide
Now we have to divide 879.75 by 100 because 100x=879.75
879.75 divided by 100 is 8.80
So now we know that they paid $8.80 just for the tip.
Add
Now all we have to do is add 8.80 to 58.65
58.65 plus 8.80 is 67.45
The Kerwoods paid $67.45 altogether.
Answer:
The answer to your question is x = 3; y = 3
Step-by-step explanation:
Data
angle = 45°
Opposite side = x
Adjacent side = y
hypotenuse = 3√2
To solve this problem, use trigonometric functions.
1) To find x, use the trigonometric function sine.
sin Ф = Opposite side / hypotenuse
-Solve for Opposite side (x)
Opposite side = hypotenuse x sin Ф
-Substitution
Opposite side = 3√2 sin 45
-Simplification
Opposite side = 3√2 (1 / √2)
Opposite side = 3(1)
-Result
x = 3
2) To find y use the trigonometric function cosine
cos Ф = Adjacent side / hypotenuse
-Solve for Adjacent side
Adjacent side = hypotenuse x cos Ф
-Substitution
Adjacent side = 3√2 x cos 45
-Simplification
Adjacent side = 3√2 x (1/√2)
Adjacent side = 3(1)
-Result
y = 3
700,000 + 70,000 + 70
is your answer
hope this helps :D
