Is there anyway you could reupload the picture or write it on paper so we can see the full question ? (:
Answer:
B≈103.8° , a≈11.3 and C≈24.2°
B is correct.
Step-by-step explanation:
Given:
Using sine find rest part of the triangle.
Sine law:
Cosine Law:
where,
Hence, B≈103.8° , a≈11.3 and C≈24.2°
Answer:
TRUE
Step-by-step explanation:
A complex number is represented as z = x + iy
Given the complex number -5i, this can also be written as;
z = 0-5i
Get the modulus
|z| = √0²+(-5)²
|z| = √25
|z| = 5
Get the argument
theta = arctan(y/x)
theta = arctan(-5/0)
theta = arctan(-∞)
theta = -90degrees
Since tan is negative in the 2nd and fourth quadrant
in the fourth quadrant, theta - 360 - 90
theta = 270 degrees
Express in polar form;
z = |z|(cos theta + i sintheta)
z = 5(cos270°+ison270°)
Hence the statement given is TRUE
The cost for a party here is the base fee,
plus charges for any additional guests.
So we know for a 15-person party, the price is going to be $100. That's a flat (constant) cost.
We know that for each additional person, we add $12. So for
more people, the cost is $
.
Since 100 is constant here, we make that our y-intercept. Even with no additional guests, the cost is still $100.
We add to write
. 12 is the constant rate of change (slope).
