Answer:
The measure of the reference angle is
Step-by-step explanation:
The reference angle of an angle is the magnitude of the smallest angle it makes with the x-axis. In this case, we have (*Note: , use to convert to degrees)
Step-by-step explanation:
Factorise completely
a 6x2 + 18x
Common factors
6x(x+3)
b 8y3 – 2y4
2y^3(4-y)
c 16xy – 8xy?
8xy(2-1)
8xy
8 Expand and simplify
a 4(x + 3) + 7(x - 1)
4x+12+7x-7
11x+5
b x(x – 6) – x(4x – 2)
x^2-6x-4x^2+2x
-3x^2-4x
-x(3x+4)
C x(3x2 + 4) + 2x(5x2 + 9)
3x^3+4x+10x^3+18x
13x^3+22x
x(13^2+22)
Answer:
We conclude that everyone should receive 2/3 cookie.
Step-by-step explanation:
We know that everyday Mary and Laura walk to Mrs. Peterson's house to visit her. She always gives them each a Swedish cookie. One day when Mary and Laura walked home, they decided they would share their cookies with Baby Carrie.
They have a total of 2 cookies. So 2 cookies should be divided into 3 equal parts.
We calculate 2/3=0.666.
We conclude that everyone should receive 2/3 cookie.
