The angle of depression from the hot-air

Mathematics
1 answer:
BlackZzzverrR [31]1 year ago
3 0

Answer:

3497.47 feet

I think it's the answer because when you look where I've drawn...that's where the angle of depression is and 6600 is the hypotenuse, so you use the sine method where you have opposite over hypotenuse

\sin(32 = opposite \6600)

and you'll get your answer as 3497.47

2. Sandi can run for one hour at a constant speed of 348 cm per second. Marci can run for one
Zanzabum

Answer:

Marci is the faster runner.

Step-by-step explanation:

Sandi can run 348 cm in a second. Let's find out how many cm she can run in a minute: in a minute there are 60 seconds. So lets multiply 348cm times 60, this gives you 20,880. That is how much she travels in a minute, now let's find out how much she runs in an hour: if she runs 20,880 cm in an minute and there are 60 minutes in an hour, then all you have to do is multiply 20,880 times 60, this gives you 1,252,800. That is how many cm she runs in an hour. Now let's change from cm to miles. There are 160,934 cm in a mile. If we divide 1,252,800 by 160,934 this will give you

The straight lines passing through these pairs of points (2, 5) and (4, 7) ,(−4, 2) and (1, 7) are,
Taya2010 [7]

Answer:

The line passes (2, 5) and (4, 7) has slope:

S = (7 - 5)/(4 - 2) = 2/2 = 1

The line passes (1, 7) and (-4, 2) has slope:

S = (2 - 7)/(-4 - 4) = 5/-5 = -1

The multiplication of two slope is  1 x (-1) = -1

=> Two lines are perpendicular

Hope this helps!
