Answer:
Step-by-step explanation:
8b-4b+8-3=4b+5
4b=-5
b=-5/4=1 1/4
Factor:
2sin^2x-sinx = 0
sinx(2sinx - 1) = 0
Therefore the solutions are when:
sin x = 0
And
sinx = 1/2
So sinx = 0
is true when x = 0 and pi and all the angles coterminal with these points. Thus, the answer is x = pi*n, (where n is some integer)
sinx = 1/2
is true when x = pi/6 and 5pi/6 and the angles coterminal with these points.
Thus, the answer is x = pi/6 + 2pi*n (where n is some integer)
and x = 5pi/6 + 2pi*n (where n is some integer)
We know $65 were spent on his ticket and some shirts.Which he used 32.25 which leaves us with 27.75 and a shirt cost 14 and 50 cent .
SO you need to divide 27.75 in 14 and 50 cents which is equal to
14 plus 14 equals 28
75 plus 50 equals 1 and 25 cents
David can buy two shirts
Hope this helped
12+18=30 so together they have $30.00 in all.
