Answer:
= sqrt(53)
Step-by-step explanation:
|7-2i| means find the distance
d = sqrt(real part^2 + imaginary part^2)
= sqrt(7^2 + (-2)^2)
= sqrt(49+4)
= sqrt(53)
The answer is D
To find the constant of proportionality divide y by x.
18/4 = 4.5
Add -11 and 15 to get 4
x^2 + 4
sin2(t) + cos2(t) = 1. tan2(t) + 1 = sec2(t). 1 + cot2(t) = csc2(t)
