Since the line goes through (0, 0), it can be described by
y = kx
You are given the point (12, 72), so you know
72 = 12k
6 = k . . . . . . . divide by 12
Then the equation of the line is ...
y = 6x
32w
He rides 32 miles every week, so if rode his bike for 3 weeks, he would’ve rode 32 x 3 = 96 miles
Answer:
The second choice
Step-by-step explanation:
You have to look at the placement of the letters in the first expression and compare to the answer choices and see which line up correctly.
Answer:
g ≈ 34.7 in
Step-by-step explanation:
The law of sines is useful for this:
f/sin(F) = g/sin(G)
Multiplying by sin(G), we have ...
g = f·sin(G)/sin(F) = (61 in)·sin(34°)/sin(79°)
g ≈ 34.7 in
You have to do some trigonometric transformations :
sin ( 11π/2 ) = sin ( 8π/2 + 3π/2 ) = sin ( 4π + 3π / 2 ) = sin ( 3π / 2 ) =
= sin 270° = -1
