What is 5/6 of 3
5/6 of 3 = 2 1/2
That means it will take her 2 1/2 square meters of fabric to make a skirt
HOPE THIS HELPED :DDD
The function rule I will be using is this:
![y = 2x + 5](https://tex.z-dn.net/?f=y%20%3D%202x%20%2B%205)
Four ordered pairs that could represent this linear function are:
(0, 5)
(1, 7)
(2, 9)
(3, 11)
Answer:
One root is 90 degrees or π/2 radians.
Drawing a graph we get all the roots:
nπ and π(n - 1/2)
Step-by-step explanation:
Sin^3A.cos A + Cos^ 3 A = Cos A
Divide through by cos A
sin^3A + cos^2A = 1
sin^3 A = 1 - cos^2 A
sin^3 A = sin^2 A
sin A = 1
So one root is A = 90 degrees or π/2 radians.
Checking this result:
(sin 90^3 * cos 90 + (cos 90)^3 = 1 * 0 + 0 = 0
cos 90 = 0
So this is correct..

Step-by-step explanation:
The missing options are:
![a.\ 15 + 6\\b.\ -6 + (-15)\\c.\ 15 + (-6)\\d.\ 6 + (-15)](https://tex.z-dn.net/?f=a.%5C%2015%20%2B%206%5C%5Cb.%5C%20-6%20%2B%20%28-15%29%5C%5Cc.%5C%2015%20%2B%20%28-6%29%5C%5Cd.%5C%206%20%2B%20%28-15%29)
For this exercise it is important to remember the mulitplication of signs:
![(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-](https://tex.z-dn.net/?f=%28%2B%29%28%2B%29%3D%2B%5C%5C%28-%29%28-%29%3D%2B%5C%5C%28-%29%28%2B%29%3D-%5C%5C%28%2B%29%28-%29%3D-)
By definition, the sum is the result of an addition.
Therefore, you need to add the numbers given in the exercise (-15 and 6) in order to find its sum. This is:
(Since the greatest number has a negative sign, the sum is negative).
Knowing this, you can check each option to find the expression whose sum is -9:
![a.\ 15 + 6=21\\\\b.\ -6 + (-15)=-6-15=-21\\\\c.\ 15 + (-6)=15-6=9\\\\d.\ 6 + (-15)=6-15=-9](https://tex.z-dn.net/?f=a.%5C%2015%20%2B%206%3D21%5C%5C%5C%5Cb.%5C%20-6%20%2B%20%28-15%29%3D-6-15%3D-21%5C%5C%5C%5Cc.%5C%2015%20%2B%20%28-6%29%3D15-6%3D9%5C%5C%5C%5Cd.%5C%206%20%2B%20%28-15%29%3D6-15%3D-9)
The answer is the option "d".
