Can you guys help me, I'll really appreciate it, I need this to 14 February ill give you 30 points

dmitriy555 [2]

Answer:

1. f(x) Domain [-3,∞) Range [0,∞)

2. g(x) Domain (-∞,∞) Range [√3, ∞)

3. h(x) Domain [3,∞) Range [0,∞)

4. i(x) Domain (-∞,-√3]∪[√3,∞) Range [0,∞)

5. j(x) Domain (-∞,∞) Range [0,∞)

6. k(x) Domain (-∞,∞) Range [0,∞)

7. f(x) Domain (-∞,∞) Range [3,∞)

Exercise 2 : no there is not an inverse. in about to have an inverse you have to have x and y. yes. if you restrict the domain of the finction so that its 1 to 1 which creates a new function youll have an inverse.

I need help with this

Zanzabum

Answer:

$\text{ 78 miles per hour}$

Step-by-step explanation:

Given the linear function for the traffic fines:

$f(s)=14(s-60)+40$

If a fine comes to $292, substitute f(s)=292 and solve for "s" to find the speed of the person:

$\begin{gathered} 292=14(s-60)+40 \\ 292=14s-840+40 \\ 14s=292+840-40 \\ 14s=1092 \\ s=\frac{1092}{14} \\ s=78\text{ miles per hour} \end{gathered}$

How to slove this<br>i need surface and radius

ahrayia [7]

Answer:

e) Area of shaded part = a^2(1 - 0.25 π). Radius of the arc = 0.5a.

f) Area of shaded part = 0.5a^2( π - 2). Radius of the arcs = a.

Step-by-step explanation:

e) Area of shaded part = area of the square - area of the 2 semicircles

= a^2 - 2 * 0.5 π r^2

= a^2 - π (0.5a)^2

= a^2 - 0.25 a^2 π

= a^2(1 - 0.25π )

The radius of the semicircle is 0.5a.

f) Split the shaded area into 2 parts by drawing the diagonal of the square through the shaded area.

The area of one half = the area of the quarter circle - area of the triangle formed by the diagonal

= 0.25 π a^2 - 0.5a^2

= 0.25 a^2 π - 0.5a^2

= 0.25a^2( π - 2)

So the total area of the shaded area

= 2 * 0.25a^2( π - 2)

= 0.5a^2( π - 2).
