<h3>Answer:</h3>
The Second one {(-8,-7), (4,-2), (2,9), (-8,8)}
<h3 /><h3>
Step-by-step explanation:</h3>
A function only gives ONE out put for a given value. But the second set has two outputs if we input -8, it gives you -7 and 8 so this must not be a function.
Answer:
18
Step-by-step explanation:
36/4=9 9/2=4.5 4.5+4.5+4.5+4.5=18
Answer:
40 mph
Step-by-step explanation:
One hour includes 60 minutes
8/60=0.13(3 repeating)
You only need 15 minutes of time
0.13(3 repeating)*15=2
8+2=10 miles
15 minutes is 1/4 of an hour
10*4=40 mph
The length of the diagonal of the canvas is approximately 27 degrees.
The height of the rectangular canvas must reach 18 inches. It must form a 48 degrees angle with the diagonal at the top of the canvas.
<h3>Length of the diagonal Canvas</h3>
Therefore, the length of the diagonal can be found as follows:
Using trigonometric ratio,
- cos ∅ = adjacent / hypotenuse
where
∅ = 48°
adjacent side = Height of the rectangle = 18 inches
hypotenuse = Length of the diagonal
Therefore,
cos 48° = 18 / h
cross multiply
h = 18 / cos 48°
h = 18 / 0.66913060635
h = 26.9005778976
length of the diagonal ≈ 27 inches
