Answer:
2.77
Step-by-step explanation:
2.9 cos (17) = 2.77
The correct answer is the last number line because with an inequality, the "equal to" sign below the "<" or ">" means the circle should be filled in. The line is traveling in a negative direction because the inequality says that n is less than -1.
1/2*-3 1/2 = -21/4 = -5 1/4= <em>-5.25</em>
I hope this helps!!
(35/50)=(x/100)
35x100=3500
3500/50=70
so the answer is 70%
Suppose one of the roots is a the second is 2a. The factors will be:
(x-a) and (x-2a)
thus
(x-a)(x-2a)=x^2+6x+q
x^2-xa-2ax+2a^2=x^2+6x+q
taking corresponding terms we shall have:
-2ax=6x
solving for a we get
-2a=6
thus
a=-3
but
q=2a^2
substituting the value of a we get:
q=2(-3)^2
q=2*9
q=18
