He liked about 8-9 colors because all you have to do is subtract 33% which equals 8.71
Step-by-step explanation:
cot(x) cos(x) + cot(x) = 0
cot(x) (cos(x) + 1) = 0
cot(x) = 0 or cos(x) = -1
cot(x) = 0
x = π/2, 3π/2
x ≠ 0, π
cos(x) = -1
x = π
Therefore, the answer is x = π/2, 3π/2.
Answer:
Improper fraction = 10/3 cups
Mixed fraction = 3 1/3 cups
Step-by-step explanation:
Given;
Sam uses 2/3 cup of sugar to make cookies
Rate = 2/3 cup per batch
To make 5 batches, he would need;
Amount = number of batches × rate per batch
Amount = 5 batches × 2/3 cups per batch
Amount of sugar he would need = 10/3 or 3 1/3 cups
Answer:
positive
Step-by-step explanation:
To solve this, we can look at the unit circle (see attached photo), We know:
(0,1) = π/2
(-1, 0) = π
(0, -1) = 3π/2
(1, 0) = 0
Across the circle, we know that π/3 is between 0 and π/2. Therefore, as the unit circle line between that is positive in the x direction (cos), we can say that cos(π/3) is positive
