Answer:
-5/6, -1/6, 5/3
Step-by-step explanation:
The vertical line test is used to see if a drawn line on a graph is truly a function or not. A function is defined as for every input (x value) there is ONE output (y value). So if you're able to draw any vertical line through a point and get one y value for every x value, then the graph drawn is a true function. If you drawn a vertical line and you get two y values for one x value, then the graph is not a true function
Answer:
Angle between the two vectors is 20.7718°.
Step-by-step explanation:
The given two vectors are x = (1,2,3,4) and y = (4,2,4,5)
Now the dot product between two vector is defined as
x.y = ║x║║y║cosθ
Now, x.y( dot product of x and y) = 1×4 + 2×2 + 3×4 + 4×5 = 40
║x║= 
= 
║y║= 
'
Thus, we get
40 = ×
×Cos θ
Thus, Cos θ = 
Cos θ = 0.935
θ = 
θ = 20.7718°
It should be 30.4
Multiply 8 by both numbers in the parentheses. -8x7 - 8x(-3.2)
You should end up with -56 + 25.6
Next you add those two numbers and you end up with 30.4.
I hope this helps!
