Answer:
20 bracelets and 10 necklaces
Step-by-step explanation:
If he wants to make 10 more bracelets than necklaces, you know the bracelets must be at least 10 more than the necklaces.
looking at the answer, the only one that satisfies this is the last one:
20 bracelets and 10 necklaces.
The graph really does not help you here.
You correct the answer is 894.09
<span>As we know
cos theta-1= 0
cos theta = 1
Now Look at a graph of the cosine function
, and you will observe that cos theta = 1
at the points X = 0, and X = 2pi
hope it helps</span>

Step-by-step explanation:
Answer:
Does exist -- It only exists when the determinant does not equal zero.
Step-by-step explanation:
The inverse of a matrix is the transpose of the cofactor matrix, divided by the determinant. If the determinant is zero, the result of the division is undefined and the inverse does not exist.
__
For this matrix, the determinant is (-2)(18) -(9)(4) = -72. The inverse exists.
