Answer:
14
Step-by-step explanation:
To find x, you will need to use sine. If you want to find y, use cosine:
sin 45 = x / 14 sqrt(2)
x = 14
(Since this is a 45 45 90 special triangle, x and y have the same length)
Since I talk about special triangles, 45 45 90 triangles are very simple:
To find the other two side lengths, just divide the hypotenuse by sqrt 2
14 sqrt(2) / sqrt(2) = 14
So both ways will still lead to 14
Didn't get the question quite well...
The domain is anything x is and the range is anything y is. Therefore, to find the domain and ranges in #16 and #18, just copy down the numbers from the charts.
#16
Domain (x): 100, 120, 150, 170
Range (y): 5.4, 3.5, 2.7, 0.2
#18
Domain (x): 20, 25, 35, 40
Range (y): 12, 15, 21, 24
Answer:
A. Vertical multiplication
Step-by-step explanation:
What happens:
What happens here is that each term on the first parenthesis multiply each term on the second paranthesis, that is, the application of the distributive property, which is the most widely used procedure to solve a vertical multiplication, meaning that the answer is given by option a.
Answer:
Neither
Step-by-step explanation:
First find the slope for both lines.
m= slope
Line 1: (y2-y1)/(x2-x1)
2-5/4-6
=-3/-2
m=3/2
Line 2: (y2-y1)/(x2-x1)
8-(-1)/2-(-8)
m=9/10
These lines are neither parallel or perpendicular because they don't have the same slope (parallel lines), and they don't have opposite reciprocal slopes either (perpendicular lines).
