Answer:
C) 36
Step-by-step explanation:
You have to add all the numbers together and then divide by the amount of numbers, in your case 5.
1 meter would because 1 milimeter would be the size of your fingernail
Answer:

Step-by-step explanation:
Given the following question:
Point A = (4, 8) = (x1, y1)
Point B = (-3, 5) = (x2, y2)
In order to find the slope any two points given we use the formula to find slope or rise/run.



The reason why the students answer is incorrect because he substituted incorrectly. More specifically the run part of the formula for slope. The formula for slope goes x2 - x1 which means it should be -3 - 4, not -4 - 3, which will give you the answer -7.
Hope this helps.
Answer:
64°
Step-by-step explanation:
This is a question on angle properties.
Angle y + 37 + 79 = 180 (Sum of angles in a triangle)
Angle y + 116 = 180
Angle y = 180 - 116 = 64°
Step-by-step explanation:
y = -3x² + 12x - 33
y = -3[x² - 4x + 11]
y = -3[(x - 2)² + 7]
Since the coefficient of x² is negative, the curve concaves downwards and has an absolute maximum value. This happens when x = 2, y = -21.
Therefore the correct option is A.
