Step-by-step explanation:
m1.m2= -1
(4y = -2x -9)= (y = -1x/2 -9/4)
-1/2.m2= -1
m2 = 2
formula = y - y1 = m2 ( x - x1)
y - 10 = 2 ( x - (-7))
y - 10 = 2x + 14
y = 2x + 24
Your distance is 1424 and your rate is 356. As you said, d = r*t. Since you don't have the time you would do 1424 divided by 356. This leaves you with a time of 4 hours. (Don't forget units!)
Answer:
The distance of the plane from the base of the tower is 25.5 foot.
Step-by-step explanation:
As given
Max is in a control tower at a small airport.
He is located 50 feet above the ground when he spots a small plane on the runway at an angle of depression of 27°.
Now by using the trigonometric identity.

As shown in the figure given below
Perpendicular = CB
Base = AC = 50 feet

Put in the identity.



Put in the above

CB = 0.51 × 50
CB = 25.5 foot
Therefore the distance of the plane from the base of the tower is 25.5 foot.
Answer:
hour 3 to hour 4
Step-by-step explanation:
that is where the slope is the least steep
8 = 4w/3
8 = 4w/3
×3 = 4w×3
24= 4w ( the two 3s cross each other out)
÷4 = ÷4
8 = w ( the two 4s cross each other out)
