Find the slope of ther line that goes through the points (-9,-4) and (-3,-6)
sleet_krkn [62]

Answer:

slope = - \frac{1}{3}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 9, - 4) and (x₂, y₂ ) = (- 3, - 6)

m = \frac{-6+4}{-3+9} = \frac{-2}{6} = - \frac{1}{3}

A pole that is 3.1m tall casts a shadow that is 1.46m long. At the same time, a nearby building casts a shadow that is 36.75m lo
Mademuasel [1]
You have to find the angle of sunlight and the pole , which then cast a shadow
length of the pole is equal to 3.1m
creating a hypotenuse of 4.52m
the angle will be
[email protected] = opposite side / hypotenuse
= 1.46/4.52
= 0.32 that's 18.66 °
now for the building sin18.66° = opposite/hypotenuse
0.32 = 36.75/ hypotenuse
hypotenuse = 114.84 m
thus using Pythagoras theorem
114.84*114.84 = 36.75*36.75 + x^2
which comes around = 108.8 roughly 109 metres long

Hello from MrBillDoesMath!

Answer:

The equations "are balanced"


Discussion:

Given that

4 + 4 = 8                 => subtracting k from both sides

4 + 4 - k = 8 -k


so the equation shown IS correct. The answer should be the equations "are balanced"


Thank you,

MrB
