Kyle is pulled back on a swing so that the rope forms an angle of 35° with the vertical. The distance from the top of the swing

set directly to the ground is 11 feet. Find Kyle’s height off the ground, 2004-04-02-02-00_files/i0270000.jpg, when he is in the pulled-back position. Round the answer to the nearest hundredth.

Answer:  Kyle's height off the ground would be 7.7 feet.

Step-by-step explanation:

Since we have given that

Angle of elevation = 35°

Distance from the top of the swing set directly to the ground = 11 feet

We need to find the Kyle's height off the ground.

We will use "Tangent of triangle":

\tan 35^\circ=\dfrac{Perpendicular}{Base}\\\\0.7=\dfrac{P}{11}\\\\0.7\times 11=P\\\\7.7\ feet=P

Hence, Kyle's height off the ground would be 7.7 feet.

Hi there!


Looks like a lot of work is going on here.


Let's start by solving this equation for the x.


5x + 20y = 4


Step 1) Add -20y to both sides.


5x + 20y + - 20y = 4 - 20y 5x = -20y + 4


Step 2) Divide both sides by 5.


\frac{5x}{5}  = \frac{-20y + 4}{5}


x = -4y +  \frac{4}{5}


Final Answer:


x = -4y +  \frac{4}{5}


Now, let's solve for y.


Step 1) Add -5x to both sides.


5x + 20y + - 5x = 4 + - 5x 20y = -5x + 4


Step 2) Divide both sides by 20.


\frac{20y}{20} =  \frac{-5x + 4}{20}


y =  \frac{-1}{4} x +  \frac{1}{5}


Final Answer:


y =  \frac{-1}{4} x +  \frac{1}{5}


Hope this helps! :D


Hint - When you have two variables in an equation, and you want to solve for one, the other will end up in your answer. :)

What’s the mean of 18 23 10 39 22 17 16 15
prohojiy [21]
It would be 20
To get this answer you would add up all the answer then divide it by how many numbers there are
18+23+10+39+22+17+16+15= 160
160/8 = 20

write the equation of the line, in standard form, that is perpendicular to y=3x-2 and passes through (-7,2)
34kurt

Answer:

x+3y=-1

Step-by-step explanation:

y=3x-2 so m=3 old slope

the new slope must be -1/3 (opposite reciprocal of the old slope).

y-y0=m*(x-x0)

y-2=-1/3*(x-(-7))

y-2=-1/3x-1/3*7

y-2=-1/3x-7/3

3y-6=-x-7

The standard form for linear equations in two variables is Ax+By=C.

x+3y=6-7

x+3y=-1
