The letter weighted 7 ounces
X1=-15
X2=-1
I think this is the answer
We have that
3sin x+cos²<span>x=2
</span>3sin x+(1-sin²x)<span>=2
</span>-sin²x +3sin x=1
sin²x -3 sin x+1=0---------> up to here the procedure is correct
let
A=sin x
then
A²-3A+1=0
Group terms that contain the same variable, and move the
constant to the opposite side of the equation
(A²-3A)=-1
Complete the square. Remember to balance the equation
by adding the same constants to each side.
(A²-3A+2.25)=-1+2.25
Rewrite as perfect squares
(A-1.5)²=1.25
(+/-)(A-1.5)=1.12
first solution
(A-1.5)=1.12--------> A=1.12+1.5-----> A=2.62-----> sin x=2.62
second solution
-(A-1.5)=1.12----> -A+1.5=1.12----> A=1.5-1.12----> A=0.38---> sin x=0.38
the answer is
the equation was factored incorrectly
Answer:
2/5
Step-by-step explanation:
To figure out which is larger, you must first find the common denominator.
Multiply the denominators to find a common denominator:
8 x 5 = 40
Then, cross-multiply to find the new numerators:
2 x 8 = 16 3 x 5 = 15
You now have:
2/5 = 16/40 and 3/8 = 15/40
So, 2/5 is larger!
