Answer:
10
Step-by-step explanation:
Given expression is
.
is a complex expression.
The value of<em> i </em>is –1.
By definition of absolute value, 
Now, substitute
in the above formula.
(since <em>i </em>= –1)
(since
and
)
(Square root of 100 is 10)
= 10
Hence, the value of the expression
is 10.

Step-by-step explanation:
Answer:
First, it’s already telling you that you need to find d, which is the opposite of degree 59. This means you have to do the exact thing for degree 37. Since it’s already telling you to use sine, you need to look at the opposite side of 37 which is 98.4.
So ? is 98.4
Now, you need to find sin 59 / d.
First, plug in sin 98.4 sin (37) in your calculator (make sure it’s in degree setting)
The result is 59.2.
Now, 59.2 = sin 59 / d.
Switch sides like this: d = 59.2 sin (37)
And the answer is approximatley d = 35.6
? = 98.4
d = 35.6
Answer:
the answer should be x = -6
Step-by-step explanation:
-9x + 6y = 18
-9x + 6(-6) = 18
-9x - 36 = 18
-9x - 36 + 36 = 18 + 36
-9x = 54
-9x ÷ -9 = 54 ÷ -9
x = -6
