Answer: C is the correct answer.
Step-by-step explanation: First of all, you have to eliminate the answer choice in which the angles are different for the cosine term and for the sine term. Therefore, you can eliminate choice D.
The way that complex numbers are written are the following:
z=a+bi
r (which is considered the magnitude/number outside the parentheses)=sqrt (a^2+b^2)
tan(angle)=b/a.
Now using the information given here,
a=-6, b=6.
r=sqrt ((-6)^2+6^2)=sqrt(72)=6sqrt2
tan(angle)=6/-6=>-1
angle is equal to arctan(-1)=3pi/4.
Therefore the correct answer is C. Hope that helped!
11. x = 10, so DCE is 72. You get the measurement of x by adding 7x + 2 and x + 8 to equal 90. When you get x, you plug it in to the equation for DCE.
12. x = 17. KNM is 131. Get the measurement of x by adding both equations again, this time equaling it to 180 since it is a straight line and doesn't have a right angle. Plug in the x to the equation for KNM.
Answer:
900 divided by 3 is 300 and 3*3=9 :)
Step-by-step explanation:
Not sure what the question was, but hope this helps!
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question the equation is
y = 4x − 11
Comparing with the general equation above
<h3>Slope = 4</h3><h3>y - intercept = - 11 or ( 0 , - 11)</h3>
Hope this helps you
