Answer:

Step-by-step explanation:

1):

f(4)-f(1) = 244-484 = -240

res = -240/(4-1)=-80

so res = -80

2):

f(2)-f(0) = 1-2 = -1

res = -1/(2-0) = -1/2

so res = -1/2

Suppose cos(O) = 12/13, Quadrant I. Find sin(O). A:13/12 B:5/13 C:13/5 D:5/12

noname [10]

Answer:

B: 5/13

Step-by-step explanation:

pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = 5

sin = opp/hyp

sin 5/13

Hope this helps
