Step-by-step explanation:

A) In part 1, the bus is increasing in speed. In part 2, the bus keeps a steady pace. In part 3, the bus is slowing down. In part 4, the bus is once again keeping a steady pace. In part 5, the bus is increasing in speed once again.

B) Parts 1 and 5 are increasing, part 3 is decreasing, and parts 2 and 4 are constant.

C) This graph is non-linear. Linear means straight, and this graph is constantly increasing and decreasing. Thus, it is non-linear.

Super urgent!<br><br> Solve the equation for all real values of x. 3tan^2 = sqrt3 tanx

lutik1710 [3]

f(x) = tan2(x) + (√3 - 1)[tan(x)] - √3 = 0

tan2(x) + √3[tan(x)] - tan(x) - √3 = 0

Factor into

[-1 + tan(x)]*[√3 + tan(x)] = 0

which means

[-1 + tan(x)] = 0 and/or [√3 + tan(x)] = 0

Then

tan(x) = 1

tan-1(1) = pi/4 radians

For the other equation

[√3 + tan(x)] = 0

tan(x) = -√3

tan-1(-√3) = -pi/3

so that

x = pi/4 or -pi/3 in the interval [0, 2pi]

Please help this is my last question and I've been waiting 40 minutes

Check the picture below.

now, notice, each square in the grid is 2 units, so, x = 8, y = 10 and x = 13, y = 5

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\
of\ change
\end{array}\\\\
-------------------------------\\\\
\qquad 
\begin{cases}
x_1=8\\
x_2=13
\end{cases}\implies \cfrac{f(13)-f(8)}{13-8}\implies \cfrac{5-10}{13-8}\implies \cfrac{-5}{5}\implies -1$

-1 or -1/1, or -(vertical distance) / (horizontal distance)

the negative means is dropping, and 1/1 means, for every foot going down, it moves farther away from the kicker by 1 foot.
