It is indeed false.

\sin^{-1}x is a function that takes values of x between -1 and 1, and takes on values between -π/2 and π/2. Most importantly, it's a function that takes *one* value in its domain and assigns it to exactly *one* value in its range. Hence \sin^{-1}x is one-to-one.

It's true that \sin x=\frac45 has infinitely many solutions, but \sin x itself is not one-to-one.

Answer:

-3/2

Step-by-step explanation:

Find two points on the graph: (-1,2) and (1,-1).

Start at point (-1,2) and go down until you are at the same "x-line" as the point (1,-1). You should count 3 squares. Now, count squares to the right until you reach the point (1,-1). You should count 2. So, you have 3/2. However, the line starts from the top of the left side of the graph, so the slope is negative.

I only need help on the second and third one
Iteru [2.4K]

let's first off notice that, on the 2), the sector is really half of the whole circle, and on 3) the sector is one quarter of the whole circle.

now, on 2) AB is the diameter of 4 units, therefore it has a radius of 2, or half that.

\bf \boxed{2} \\\\\\ \stackrel{\textit{area of a circle}}{A=\pi r^2}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=2 \end{cases}\implies A=\pi 2^2\implies A=4\pi \\\\\\ \stackrel{\textit{half of that}}{A=2\pi}\implies A=\stackrel{\textit{rounded up}}{A=6.3~ft^2} \\\\[-0.35em] ~\dotfill

\bf \boxed{3} \\\\\\ \stackrel{\textit{area of a circle}}{A=\pi r^2}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=20 \end{cases}\implies A=\pi 20^2\implies A=400\pi \\\\\\ \stackrel{\textit{one quarter of that}}{A=100\pi }\implies \stackrel{\textit{rounded up}}{A=314.2~in^2}
