Find the equation of the line that passes through the point left-parenthesis 1 comma 8 right-parenthesis and is perpendicular to
Furkat [3]

Don't be shy about using actual parentheses and commas.

Line through (1,8) perpendicular to    

-\dfrac 4 5 x + \dfrac 5 4 y = -4

The perpendicular family is gotten by swapping the coefficients on x and y, negating exactly one of them.   The constant is given directly by the point we're through:

\dfrac 5 4 x + \dfrac 4 5 y = \dfrac 5 4 (1) + \dfrac 4 5 (8) = \dfrac 5 4 + \dfrac{32}{5}

Let's clear the fractions by multiplying both sides by 20.

25x + 16y = 25 + 128 = 153

Might as well stop here.

Answer: 25 x + 16 y = 153

( Will hand out brainiest) A California condor left its cliff-side nest and soared downwards at a rate of 16 meters per second.
svet-max [94.6K]

First calculate the distance covered going down:

d_down = (16 m / s) * 8 s = 128 m

 

Then the distance going up is:

d_up = 71 m

 

So the distance from the ledge to the nest is:

d = 128 m – 71 m = 57 m

 

Therefore the elevation is:

<span>elevation = 1364 m + 57 m = 1421 m</span>

height = volume / (PI*radius^2)

height = 271.4 / (PI * 36)

height = 2.3997028642

height = 2.4 inches (rounded)
