What is the best estimate for the number of people in line at 7.A.M

Keith_Richards [23]

We have been given the equation

$y=-5.131x^2+31.821x-3.333$

It represents the number of people standing to catch a commuter train x hours after 5 A.M.

Now, in order to find the number of people in line at 7 a.m. , we need to substitute x= 2 in the above equation.

$y(2)=-5.131(2)^2+31.821(2x)-3.333\\y(2)= 39.785 \approx 40$

Therefore, the number of people in the line at 7 a.m. is 40

D id the correct option.

Find the missing angle! Please add an explanation!

AlladinOne [14]

Answer:

The answer is: $58^\circ$

Step-by-step explanation:

If we add the angles inside a triangle, we must have $180^\circ$ . So we have an $57^\circ$ angle and an $65^\circ$ angle, their sum is $122^\circ$ , so the missing angle must be $180^\circ-122^\circ=58^\circ$
