Answer:

$0$

Step-by-step explanation:

Given:

$f(x) = \begin{cases} -x -2 &, &x < 0 \\ x &, &0 \leqslant x < 3 \\ x^2 -1 &, &3 \leqslant x \end{cases}$

Solving for $f(0)$ :

$f(0) = x \text{ when } x = 0 \\ f(0) = 0$

1) Either $\ell \parallel p$ or $\ell$ ∦ $p$ (only two possibilities)

2) Assume $\ell \parallel p$ (one of two possibilities)

3) $\angle 1 \cong \angle 2$ (if two parallel lines are cut by a transversal, the corresponding angles are congruent)

4) But $\angle 1$ is not congruent to $\angle 2$ (given)

5) So $\ell$ ∦ $p$ (only other possibility)

I don’t really get this question so if anyone knows it please help

Mars2501 [29]

Answer:

$116.82\:\text{square inches}$

Step-by-step explanation:

The window consists of a large square and 4 smaller triangles on the outside. The side length of this square is marked as 10, and therefore the area of this square is $10^2=100\:\mathrm{in^2}$ .

The area of a triangle is given by $\frac{1}{2}\cdot b\cdot h$ . Since the problem states that the overlapping squares are congruent, both legs of the triangle will be $2.9$ and intersect at a $90^{\circ}$ angle.

Thus, the sum of all four triangles is $\frac{1}{2}\cdot 2.9\cdot 2.9\cdot 4=16.82\:\mathrm{in^2}$ .

Therefore, the area of the window is:

$100+16.82=\boxed{116.82\:\mathrm{in^2}}$
