Answer:
540°.
Step-by-step explanation:
On a unit circle, cos θ = -1 at 180°.
However, cos θ has a period of 2π, or 360°. This means that cos θ will equal to -1 again after 2π.
To solve for the angle:
180° + 360° = 540°. This is the next angle at which cos θ = -1.
Answer:
0.85 I believe
Step-by-step explanation:
Answer:
$24.50
Step-by-step explanation:
Money saved for each shirt:
=$9. 10/2
=$4.55
Original price of the shirt:
=$19. 95 + $4.55
=$24.50
So we use 80% to multiply 20,000
we get 16000
the answer is just 16,000
Answer:
c) 30
The determinant of Given Matrix |A| = 30
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given Matrix
The determinant of |A|
we know that determinant of matrix
|A| = |ad -bc|
|A| = -2(-15-0)-2(0-0)+b(0-0)
|A| = 30
