$T^{-2}:(x,y)$
means doing the inverse transformation twice.
The forward transformation is given as
$T:(x+3,y+1)$
so the inverse transformation is
$T^{-1}:(x-3,y-1)$
and
$T^{-2}:(x,y)=T^{-1}(x-3,y-1)=(x-6,y-2)$

Need help finding intervals where the function is decreasing.

umka21 [38]

$f(x)=-5x-5\sin x\implies f'(x)=-5-5\cos x$

$f$ is decreasing on some interval $(a,b)$ if $f'(x)$ for all $x\in(a,b)$ . Similarly, $f$ is increasing on $(a,b)$ if $f'(x)>0$ for all $x\in(a,b)$ .

On the domain $0\le x\le2\pi$ , we have

$-5-5\cos x=0\implies\cos x=-1\implies x=\pi$

as the only critical point. So we need to check the sign of $f'$ on two intervals, $(0,\pi)$ and $(\pi,2\pi)$ .

On $(0,\pi)$ , pick any test value. Suppose we take $x=\dfrac\pi2$ . Then $f'\left(\dfrac\pi2\right)=-5$ , so $f$ is decreasing on this interval.

On $(\pi,2\pi)$ , you'd find that $f'>0$ , so $f$ is increasing on this interval.

Can i please have some actual help with this?

jek_recluse [69]

Answer:

x = 286.01 inches

Step-by-step explanation:

Given that,

Height of the ramp, H = 20 inches

Angle of elevation, $\theta=4^{\circ}$

We need to find the value of x. It can be solved using trigonometry as follow :

$\tan\theta=\dfrac{P}{B}$

Where

P is perpendicular and B is base

So,

$\tan(4)=\dfrac{20}{x}\\\\x=\dfrac{20}{\tan(4)}\\\\x=286.01\ in$

So, the value of x is equal to 286.01 inches.
