Answer:
Situation B is a function.
Step-by-step explanation:
We know that,
A function is a relation in which every element in the domain i mapped to a unique element in the co-domain.
<em>That is, every element in the domain must have a unique image.</em>
So, we see that,
Situation A = {student's name, all the colors that the student likes}
Here, the students can have more than one color which they like.
Thus, this relation is not a function.
Situation B = {student's name, the student's favorite math teacher}
Here, the students can have only one favorite math teacher.
So, this relation is a function.
I’d say A: congruent by SSS because the sides are labeled as equal and they share the other side.
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
Answer:
1.21 * 10^25.
Step-by-step explanation:
11 *10^11 * 12 * 10^2
= 11*12 * 10^11 * 10^12
= 121 * 10^(11+12)
= 121 * 10^23
= 1.21 * 10^25.
Note: True Scientific notation is N * 10^n where 1 ≤ N < 10.
