Answer:
D
Step-by-step explanation:
In a 30-60-90 triangle, if the short leg is x, then the long leg is x√3, and the hypotenuse is 2x.
Here, the hypotenuse is 10. So the short leg is:
10 = 2x
x = 5
If the short leg is 5, then the long leg is 5√3.
we know that
speed = (total distance)/(total time)
so, total distance =60+180+540+660
total distance =1440 mi
total time =10+30+90+110
total time =240 min
now, we can change time into hours
total time =
total time =4 hours
now, we can find speed
speed of the plane in miles per hour is 360 mph...........Answer
Ok so you are correct that x is input and y is output
the
you could be talking about a function in general or a kind of function normally used called a one-to-one function which I will assume you are talikning about
one-to-one funciton has that for every input, there is only 1 output, ie, x never repeats with a diffent y
example
(1,2), (2,2) is a function since x didn't repeat
(1,2), (1,3) is not since x repeats with a different y
points given are
(-5,1),(-3,-2), (3,0),(1,1),(2,0),(6,4)(8,-2),(8,7)
we see that the points (8,-2) and (8,7) make it not a function since it is the same input (8) that gives 2 different outputs
professor octavious is wrong since 8 repeats
Answer:
1/2
Step-by-step explanation:
1/2 simply because when long division is used to convert it in decimal, it is gonna be the largset
Answer:
X=-2.5
4-(2x+4)=5
cancel out 4 and -4
-2x=5
-x=2.5
x=2.5
hope this helps man :)
