lawyer [7]

Answer:

c = -5

d = -10

Step-by-step explanation:

A biologist is tracking a bird when it was at A.

Coordinates of point A are (2, 4).

This bird moves from point A to point B.

Coordinates of the point B are (-3, -6).

Vector form of vector represented by \overrightarrow{AB}=

By substituting the coordinates of points A and B,

\overrightarrow{AB}=

      = < -5, -10 >

\overrightarrow{AB}=\binom{-5}{-10}

By comparing it with the vector form of [cd]

c = -5

d = -10

Find the point on the terminal side of θ = 3pi/4 that has a y coordinate of 1. Show your work for full credit.
bagirrra123 [75]
Ok, we know the angle is 3π/4, and that y-coordinate is 1, hmm what's "x"?

\bf tan(\theta)=\cfrac{y}{x}\qquad tan\left( \frac{3\pi }{4} \right)=\cfrac{1}{x}\implies \cfrac{sin\left( \frac{3\pi }{4} \right)}{cos\left( \frac{3\pi }{4} \right)}=\cfrac{1}{x}\implies \cfrac{\frac{\sqrt{2}}{2}}{-\frac{\sqrt{2}}{2}}=\cfrac{1}{x}&#10;\\\\\\&#10;-1=\cfrac{1}{x}\implies x=-1\qquad \qquad \boxed{(-1,1)}
