a plane takes off at an angle of elevation of 15 degrees and travels in a straight line for 3,000 meters. What is the height of
nevsk [136]
SOH CAH TOA tells you the sine function of an angle gives the ratio of opposite side to the hypotenuse of the right triangle.
  Sin = Opposite/Hypotenuse
In this problem, the angle is 15°, the hypotenuse is 3000 m and we want to find the length of the opposite side (the height above the ground).

  sin(30°) = height/(3000 m)
Multiplying by 3000 m, we get
  height = (3000 m)*sin(30°) = 1500 m

The height of the plane at that instant is ...
  1500 m

Juliette [100K]

Answer:

Step-by-step explanation:

1) So -8+2v<2, 2v<10, v<5. That means that at "5" on the axis, you'll draw a circle that's <em>not</em> filled in (because it's <5, not \leq5) and then draw a box-y thing to the left. Sorry, can't really describe it, but if you look at the picture attached, you'll understand

2) -12m-8\leq-5m-7m, so -12m-8\leq-12m, -8\leq0. This one doesn't have a variable... so you can't really graph it?

Make p the subject of the relation A is equal to 1/2 ( p + b) h​
Amanda [17]

Answer:

2A /h  -b =p

If you need it with a common denominator

(2A -bh)/h = p

Step-by-step explanation:

A = 1/2 ( p+b)h

Multiply each side by 2

2A =  ( p+b)h

Divide by h

2A/h =  ( p+b)h/h

2A/h =  ( p+b)

Subtract b

2A/h   -b =   p+b -b

2A /h  -b =p

If you need it with a common denominator

(2A -bh)/h = p
