Brums [2.3K]

Answer:

  5.6 feet

Step-by-step explanation:

Assuming your zip line equation is supposed to be ...

  y = -8/3x +8

we can rewrite it to general form:

  8/3x +y -8 = 0

  8x +3y -24 = 0 . . . . multiply by 3

Now, we can use the formula for the distance from a point to a line:

  d = |ax +by +c|/√(a²+b²) . . . . . distance from (x, y) to ax+by+c=0

Filling in the values we know, we have ...

  d = |8(3) +3(16) -24|/√(8² +3²) = 48/√73 ≈ 5.6

The distance from the tree to the zip line is about 5.6 feet.

I need help on number 9

Answer:


Step-by-step explanation:

You used Pythagorean theroem which is correct as this does form a right triangle however 50 is the hypotenuse as the ladder is propped up against the wall. 30 would then be the height of the triangle and the base is unknown so...

50^{2} = 30^{2} + x^{2}

50 squared minus thirty squared gives 1600 so:

1600 = x^{2}

Therefore x is the square root of 1600 which is 40
