Answer:
Step-by-step explanation:
(3,5) , (4,8) , (x,y)
if u cant see the x coordinate, then u cant tell if it is a function.
A function CANNOT have repeating x values...they can have repeating y values, just not the x ones.
Therefore, if u could see x, u would know right away if it was a function....but if u can only see y....well....thats not enough.
just so you know....the only way those 3 coordinate pairs could be a function, would be if x was any other number besides 3 or 4......because if x was 3 or 4, u would have repeating x values
Answer:
SA = 18.2+10.4h
59.8yd²
Step-by-step explanation:
Surface area of a 3D shape is the sum of the areas of its faces. A rectangular prism is made of 2 rectangles that make the top and bottom, plus four equal, larger rectangles.
surface area = 2(small rectangles)+4(large rectangles)
surface area = 2(3.5*2.6)+4(2.6h)
SA = 18.2+10.4h
SA = 18.2+10.4h
SA = 18.2+10.4(4)
SA = 18.2+41.6
SA = 59.8yd²
Answer:
Graph of Option D represents
Step-by-step explanation:
we are given our function as
squaring on both sides we get
It represent a parabola opening towards the positive side of x axis. Hence it gives us some preliminary idea about the graph of the function we are given .
However our original function is
Domain of is all positive values of x
And square root of positive values will always result in positive values. Hence y can not be negative as the range is All positive values of y
Hence we erase the graph of below x axis to obtain the graph of
