Answer:
4/9 is left over.
Step-by-step explanation:
First make the denominators the same. 2/3=6/9. 6/9-2/9=4/9.

Step-by-step explanation:
9 is 18% of
Answer:
9 is 18 percent of 50
Step-by-step explanation:
9 = 18% x Y
9 = 18
100 x Y
Y = 3 x 100/18
Y = 50%

Answer:
Breadth = 15 cm
Step-by-step explanation:
Area = length x breadth
315 = 21 x breadth
[ dividing both sides by 21 ]
what does x equal
Answer:
2x+13=4x-1
2x=14
x=7
another solution
2x+13=-(4x-1)
2x+13 =-4x+1
6x=-12
x =-2
so solutions are 7,-2
sin 2x sin x + cos x= 0
Use the double angle identity:
sin(2x) = 2 sin(x) cos(x)
Now rewrite
sin(2x) sin(x) + cos(x) = 0
as
2 sin²(x) cos(x) + cos(x) = 0
Factor out cos(x) :
cos(x) (2 sin²(x) + 1) = 0
Consider the two cases,
cos(x) = 0 OR 2 sin²(x) + 1 = 0
Solve for cos(x) and sin²(x) :
cos(x) = 0 OR sin²(x) = -1/2
Squaring a real number always gives a non-negative number, so the second case doesn't offer any real solutions. We're left with
cos(x) = 0
Cosine is zero for odd multiples of π/2, so we have
x = (2n + 1) π/2
where n is any integer.
Answer:
f(x) approches -∞
we can see clearly in the graph that the function is decreasing toward infinity
f(x) approches 1
we can that y=1 represents an asymptote
f(x) is growing toward 1 without reaching it
