Answer:
30
Step-by-step explanation:
Draw a picture of a building and a one mile (or 5280 feet) distance to a point from the base of the building.
The angle of elevation is given as 11° and we want the height of the building or x.
tan(11°) = x/5280
5280 tan(11°) = x
1026.3 feet = x
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
Step-by-step explanation:
Standard form of a quadratic is f(x) = ax² + bx + c.
To convert to vertex form, the simplest method is to find the x-coordinate of the vertex using h = -b/(2a).
Then, plug back into the equation to find the y-coordinate of the vertex. k = f(h).
Finally, the leading coefficient is the same as the standard form, a.
f(x) = a(x − h)² + k
Another method is to complete the square.
Total number of students who did a test was 24
Number of students who scored an A is 14
Number of students who scored a B is 10
Probability that when we randomly select a student, he/she will have an A is:
(Number of students that scored A)/(Total number of students)
=14/24
=7/12
Therefore our answer is 7/12
I use it as a short way to say "okay" but I don't know how others may use it.
