257,650 rounded to the nearest hundred is 257,700 because it is right at the border (50) we have to round up.
You round them to the nearest whole number which makes it 7-5 this means the best estimate is 2
Answer:
B. 1
Step-by-step explanation:
Your answer for A is correct.
The time it take for the sub to hit the water will be the time between when the submarine started to get lowered and when its distance from the water was zero.
The sub started to get lowered at x = 0.
Now we need to solve for the smallest positive zero of the function.
This function factors to (x - 1)(x - 7)
From this we can tell that the submarine is a water level for time x = 1 and x = 7.
The smallest of these is 1, so that is when the submarine first hit the water and 7 is when it came back out.
The sub started getting lowered at x = 0 and hit the water at x = 1 and because x is in seconds, it took 1 second for the sub to hit the water.
Answer:
II. The vertical shift is up 3 spaces.
III. The square root graph will flip.
Step-by-step explanation:
The given function is
To graph this function, we need to shift the parent radical function √x , 2 units right.
Also we need to the parents function 3 units up.
Then , the negative sign tells us that the function will flip over the x-axis.
The second and 3rd options are correct.
