The answer is what the brainliest answer person (anklebreaker05) put: 1/3.

Well by now you guys already figured out this was the wrong answer before. (Based on the rating I got) :\

GUESS WHAT?

I'm not 20!! I dont know why they did that (on my profile). You'd think that I would get it correct cause im "20." Nope. We were about to learn about ratio and stuff until the coronavirus comes and then school is closed for more than months so we didn't really learn about it with the teacher. It is usually from the videos but people can't understand everything. I wanna delete this now, you know. But I don't know how to and I can't and after I re-edit this I probably don't even want to delete it. Okay, my answer was wrong. sheeshhhh.

A road perpendicular to a highway leads to a farmhouse located d miles away. An automobile traveling on this highway passes thro

pshichka [43]

Answer:

$\frac{dh}{dt}=\frac{30r}{\sqrt{d^{2}+900}}$

Step-by-step explanation:

A road is perpendicular to a highway leading to a farmhouse d miles away.

An automobile passes through the point of intersection with a constant speed $\frac{dx}{dt}$ = r mph

Let x be the distance of automobile from the point of intersection and distance between the automobile and farmhouse is 'h' miles.

Then by Pythagoras theorem,

h² = d² + x²

By taking derivative on both the sides of the equation,

$(2h)\frac{dh}{dt}=(2x)\frac{dx}{dt}$

$(h)\frac{dh}{dt}=(x)\frac{dx}{dt}$

$(h)\frac{dh}{dt}=rx$

$\frac{dh}{dt}=\frac{rx}{h}$

When automobile is 30 miles past the intersection,

For x = 30

$\frac{dh}{dt}=\frac{30r}{h}$

Since $h=\sqrt{d^{2}+(30)^{2}}$

Therefore,

$\frac{dh}{dt}=\frac{30r}{\sqrt{d^{2}+(30)^{2}}}$

$\frac{dh}{dt}=\frac{30r}{\sqrt{d^{2}+900}}$
