Hey.. Use a calc dude
Answer:
D (42,-56)
Step-by-step explanation:
Scale factor means you multiply, so you multiply (6,-8) by 7.
6 x 7 is 42 and 7 x -8 is -56. So your answer is D (42,-56).
In radians:
To get 0, only one part of the multiplication needs to be zero for the whole thing to be zero. Thus we get 2 equations:
t=0, and cos(t)=0
for the first equation, it's pretty self-explanatory and sp we get 0 as one solution.
For the second equation, cos(pi/2) and cos(3pi/2) both equal 0 so both pi/2 and 3pi/2 are answers. Since there is no bound to this problem, the actual answer is:
(2Z+1)pi/2 and 0
(2Z+1) means all odd integers
