Which representation has a constant of variation of -2.5
Neporo4naja [7]

Answer:

See explanation

Step-by-step explanation:

The constant of variation is found using the slope formula:

\frac{y_2-y_1}{x_2-x_1}

The given relation is

X : -2 , -3, -4, -5  

Y : -5, -7.5,-10,-12.5

We can use any two ordered pair to find the constant of variation.

Using (-2,-5) and (-3,-7.5), we have

m=\frac{-7.5--5}{-3--2} =\frac{-2.5}{-1} =2.5

The constant of variation is 2.5

We need to repeat this for all the options to identify the one with -2.5 as slope.

unfortunately, you did not provide the remaining options.

Pythagorean theorem
for a right triangle with legs legnth a and b and hytponuse c
a^2+b^2=c^2

the legnht of th eladder is the hypotnuse
the 3 feet is bottom leg
height is other leg

10=c
3=a
b=?
3^2+b^2=10^2
9+b^2=100
minus 9 both sides
b^2=91
sqrt both sides
b=√91
aprox
b=9.53939


answer is √91 feet or aprox 9.53939
