Answer:

Ladder = 2\frac{1}{4}\ m

Step-by-step explanation:

Given

Sections = 3

Length = \frac{3}{4}m per section

Required

Determine the length of the ladder

The length of the ladder is calculated by multiplying the number of sections by the length of each section.

So, we have:

Ladder = 3 * \frac{3}{4}\ m

Ladder = \frac{9}{4}\ m

Ladder = 2\frac{1}{4}\ m

Hence, the length of the ladder is: 2\frac{1}{4}\ m or 2.25m

masha68 [24]
If the shape of the room is a square, then the square root of the sum of the squares of the the two adjacent sides will give the diagonal.

i.e.

\sqrt{17^2+17^2} = \sqrt{2(17^2)}  \\  \\ = \sqrt{2(289)} = \sqrt{578} =24.04

Since the square root of the sum of the squares of the the two adjacent sides is 24.04 and not 18.79, therefore, the shape of the room is not a square.

Review the graph of function f(x).
s344n2d4d5 [400]

The two limits when x tends to zero are:

\lim_{x \to \ 0^-}  f(x) = 1\\\\ \lim_{x \to \ 0^+}  f(x) = 0

<h3 /><h3>How to get the limits when x tends to zero?</h3>

Notice that we have a jump at x = 0.

Then we can take two limits, one going from the negative side (where we will go along the blue line)

And other from the positive side (where we go along the orange line).

We will get:

\lim_{x \to \ 0^-}  f(x) = 1\\\\ \lim_{x \to \ 0^+}  f(x) = 0

Notice that the two limits are different, that means that the function is not a continuous function.

Solve for x<br> A) 42<br> B) 40<br> C) 45<br> D) 38
alexgriva [62]

Answer:

x = 40

Step-by-step explanation:

Using similarity theorem, we have the following:

\frac{24}{24 - 15} = \frac{x}{x - 25}

Solve for x

\frac{24}{9} = \frac{x}{x - 25}

Cross multiply

24(x - 25) = x(9)

24x - 600 = 9x

Subtract 24x from each side

- 600 = 9x - 24x

- 600 = -15x

Divide both sides by -15

40 = x

x = 40
