Answer:
I think it's false.
In mathematics, a function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set.
6 has a relation to 5 and 10.
X²+15x+36<0
at first solve quadratic equation
D=b²-4ac= 225-4*1*36= 81
x=(-b+/-√D)/2a
x=(-15+/-√81)/2= (-15+/-9)/2
x1=(-15-9)/2=-12
x2=(-15+9)/2=-3
we can write x²+15x+36<0 as (x+12)(x+3)<0
(x+12)(x+3)<0 can be 2 cases, because for product to be negative one factor should be negative , and second factor should be positive
1 case) x+12<0, and x+3>0,
x<-12, and x>-3
(-∞, -12) and(-3,∞) gives empty set
or second case) x+12>0 and x+3<0
x>-12 and x<-3
(-12,∞) and (-∞,-3) they are crossing , so (-12, -3) is a solution of this inequality
Answer:
I know this is late, but for<em> future people</em>:
I believe the answer is <u>2b+3c</u>.
Step-by-step explanation:
I'm pretty sure all you have to do is combine like terms.
I'm also taking the test at the moment.

Answer:
A) 63.43°
Step-by-step explanation:
The two vectors in polar form are ...
u = (√(9²+6²))∠arctan(-6/9) = √117∠-33.69°
v = (√(7²+4²))∠arctan(4/7) = √65∠29.74°
The angle between the two vectors is ...
29.74° -(-33.69°) = 63.49°
