Answer:

$\sqrt{85}$ ft

Step-by-step explanation:

Use the Pythagorean theorem to find the unknown side in any right triangle,

Essentially, look at it as if it was flat.

a is half of the diameter, so 2 ft.

b is your height, 9ft

$a^{2} +b^{2} =c^{2} \\2^{2} +9^{2} =c^{2} \\4+81= c^{2}\\\sqrt{85}=c$

73 POINTS ANSWER QUICKLY AND CORRECTLY, WILL GIVE BRAINLIEST

balu736 [363]

Answer:

y = -2x+4

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

= (-4-2)/(4-1)

= -6/3

= -2

point slope form

y-y1 = m(x-x1)

y-2 = -2(x-1)

distribute

y-2 =-2x +2

add 2 to each side

y-2 +2 =-2x+2+2

y = -2x+4

in slope intercept form

y = -2x+4
