For example, l is the length of short ladder we want to find

Make a comparison
ladder/wall height = ladder/wall height
l/20 = 60/50
l/20 = 6/5
l = 6/5 × 20
l = 120/5
l = 24

The short ladder is 24 ft

Set a porportion: 60/50=x/20 and solve for x=24

Show that the function of f(x) = a - x is its own inverse for all real numbers a

tatuchka [14]

f(x) = a - x

y = a - x

y + x = a - x + x

y + x = a

y + x - y = a - y

x = a - y

f-¹(x) = a - x

Answer:

729 * 10^-45

Step-by-step explanation:

Here, we want to expand the value based on the exponent

We have the power multiplying every term in the bracket

That would be;

9^3•10^-45

= 729 * 10^-45

What is the equation of the line that passes through the point (2, 1) and has a slope of 3/2?

Ilia_Sergeevich [38]

Given :-

A line having a slope of 3/2 passes through (2,1) .

To Find :-

The equation of the line .

Answer :-

According to the question ,

m = 3/2
Point = (2,1)

We know Point slope form of the line as ,

y - y¡ = m ( x - x ¡ )

Substitute ,

y - 1 = 3/2 ( x - 2 )
y - 1 = 3/2x - 3/2*2
y - 1 = 3/2x - 3
2( y -1) = 3/2x *2 - 3*2
2y - 2 = 3x - 6
3x - 2y -4 = 0

Hence the equation of the line is 3x -2y-4=0 .

How to find length of a triangle given one side and angle equladera; triangle?

serious [3.7K]

An equilateral triangle is a triangle with all equal sides, meaning, if the problem gives you one side, then it has given the length of all the sides because all sides lengths are equal. Given that you have one side and one angle, all sides will be the same length and no matter what all angles are the same and if correct the angles will be equal to 60 each.
I hope this helps some.
