Answer:
330
Step-by-step explanation:
When we are at 30 degrees on the unit circle, we are at the point (/2, 1/2) so if we go to -30 degrees (330 degrees), we will be at point (-
/2, -1/2).
Note: (cosine, sine)
Solve triangle. round to the nearest tenth

Answer:
Option C
Step-by-step explanation:
Given that u-ai + bj and v-ci + dj are vectors
We have dot product
hence inner product of u and v. So option a is true
The dot product of u and v is a scalar is true because dot product is always a scalar
The dot product of u and v is a vector. is false because dot product is only a scalar and has no direction and hence cannot be a vector
The dot product of u and v is given by the expression ac+bd
True because we multiply corresponding i components and j components and add.
So only C is not true.
Step-by-step explanation:
label the numbers (x,y) and (x2,y2)
write down the distance formula
replace the xs and ys by the numbers and then solve them
