Answer:
graph c
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
note that sin x = cos(90 - x ) ← Cofunction identity
If x = 36 then 90 - x = 90 - 36 = 54
Hence sin 36° = cos 54° → C

Just put it in Geogebra classic. It's an app that helps very much with functions!
Answer:
25 students peer teacher, 22 students per tutor, 4 tutors for 81 students
Step-by-step explanation:
You need to find the unit rate,
for the teachers, to find the unit rate would be 125 divided by 5. For tutors it would be 88 divided by 4.
Then to find how many tutors you need for 81 students you would need 4 tutors because you want to divide 81 by the unit rate we got (22), and since the answer would be a decimal (3.68.....) you would need to round the whole number up to four because you cant have a decimal of a person.
Perimeter = 2( Length + Width)
<em>Given that Perimeter = 3 1/12 feet and Width = 2/3 foot, plug the values into the formula to find the length:</em>
3 1/12 = 2( Length + 2/3)
3 1/12 = 2Length + 4/3
2 Length = 3 1/12 - 4/3
2 Length = 7/4
Length = 7/4 ÷ 2
Length = 7/4 x 1/2
Length = 7/8
<em>Now that we know the length is 7/8 and the width is 2/3, find the area:</em>
Area = Length x Width
Area = (7/8)(2/3) = 7/12
Answer: Area = 7/12 ft²
