I would say technician B is probably right when talking about a construction sight. Construction sights could be worked on in storms, near power lines, or be near power sources when doing their job. It’s also heavy so in case there is wind or something when they are attempting to scale a building, it’s not as dangerous as the aluminum.
Answer:
4/3 (= 1 1/3)
Step-by-step explanation:
2/3 - (-2/3)
= 2/3 + 2/3
= (2+2) / 3
= 4/3
= 1 1/3
Answer:
True, false, true, true.
Step-by-step explanation:
The roots zeros of a quadratic function are the same as the factors of the quadratic function. This is true because your roots are your factors—>(x-3) is a factor, x=3 is the root.
The roots zeros are the spots where the quadratic function intersects with the y-axis. No! Those are called y-intercepts!
The roots zeros are the spots where the quadratic function intersects with the x-axis. True. X-intercepts are your solutions. (x-3) graphed would the (3,0). That’s a solution.
There are not always two roots/zeros of a quadratic function, True. No solution would be when your quadratic doesn’t intersect the x-axis. One solution would be when your vertex would be on the x-axis. Two solutions is when your quadratic intersects the x-axis twice. Can there be infinite solutions? No. It’s either 0, 1, or 2 solutions.
Answer:
D. r=-1 is the correlation coefficient
