Answer:
The commutative property of multiplication states that changing the order of the numbers we are multiplying, does not change the product.
Answer:
C. 5/3 (5 sqrt 3) (8.66...)
Explanation:
You would use the SohCahToa to find out side x.
First, label your sides (10 is hypotenuse, x is the opposite, and blank side is the adjacent).
Second, figure out which part you have to use (Sin, Cosine, or Tangent). A good way to tell is of you have the missing side on top of the fraction, makes things easier.
Third, once you figure that out then plug stuff in...
Sin(theta) = O/H
Sin(60) = X/10
10sin(60) = X
8.66... = X
Ax^2+bx+c=0 is the standard form, so we add 5 to both sides to get
1*x^2+(-10)x+21=0
487.2
Find mean by adding all numbers together and then dividing by the number of numbers
Y>50
y<78
so since u cant be less that 50 u have to be more and since u cant be taller than 78 u have to be less than 78
now:
y<78 but >50
