m = change in y over change in x
m = (14-5)/(4-1)
m = 9/3 = 3
m = 3
Answer:
distance of diver 1 from the shark ≈ 18.88 m
Step-by-step explanation:
The illustration forms a triangle. The base of the triangle which is their distance apart is given as 30 m . The known angle of the triangle are 52° and 39°. To find the unknown side we subtract the sum of 52° and 39° from 180°. Note that the total angle in a triangle is 180°.
Therefore,
180 - (52 + 39) = 180 - 91 = 89
°. Now the three angle of the triangles are 52°, 39° and 89°.
Using the law of sine we can find the distance of the diver 1 from the shark.
let a = distance of the first diver to the shark.
a/sin 39° = 30/sin 89°
cross multiply
a sin 89° = 30 sin 39°
divide both sides by sin 89°
a = 30 sin 39°/sin 89°
a = 30 × 0.62932039105
/sin 89°
a = 18.8796117315
/0.99984769515
a = 18.8824876258
a ≈ 18.88 m
Well, point slope is y - y1 = m(x-x1) So A and D are out. And the negative would cancel each other out for a positive, answer being, B.
Answer:
y= -4/3x - 1/2 is the perpendicular line to y= 3/4x -1/2
Step-by-step explanation:
The slope would be the negative reciprocal of your current slope :)
+3/4 would turn into -4/3 and you wouldnt change the y intercept
hope this helps
