Persons A and B are at the beach, their eyes are 5 ft and 6 ft, respectively, above sea level. How many miles farther out is Per

Marysya12 [62]

Answer:

The radius of the earth is something like 4000 miles= about 20,000,000 feet. (Look up the exact radius of the earth to calculate the correct number yourself, I'm too lazy!)

The horizon is where you're looking at a tangent to the earth's surface. Since the tangent to a circle is perpendicular to the radius (if we assume the earth is a perfect sphere), we can set up a right angled triangle:

H...P

Where C is the centre of the earth, H is the horizon, and P is the person. CH = 20,000,000 feet. CP = 20,000,005 feet (in the case of the 5' person, that'd be me :) And there is a right angle at H.

So using Pythagoras' theorem, if d = PH, then:

d^2 = 20,000,005^2 - 20,000,000^2

=> d^2 = 200,000,025

=> d = 14142 feet (just under 3 miles)

For a 6' person:

d^2 = 20,000,006^2 - 20,000,000^2

=> d^2 = 240,000,036

=> d = 15491 feet

So the difference is 1349 feet or 0.256 miles

Repeat this exercise with the real radius of the earth (in feet) to get the correct answer, but it'll be pretty close to what I've given here

Simplify the expression x^2 + 3x + 4

Leni [432]

Answer:

( x + 4 ) × ( x − 1 )

Step-by-step explanation:

The equation in the A x ² + B x + C

The C is negative which indicates that one binomial will be negative and one binomial will be positive. The B is positive which indicates that the positive binomial will be larger than the negative binomial . The B is +3 which tells that the difference in the two factors is 3

Solve 5x + 4/y =7 and 4x + x/y =5 simultaneously.

Nuetrik [128]

9514 1404 393

Answer:

(x, y) ≈ (1.1642, 3.3930) and (3.4358, -0.39297)

Step-by-step explanation:

Solve the first equation for y, then substitute into the second.

5x +4/y = 7

4/y = 7 -5x

4/(7 -5x) = y

Then the second equation becomes ...

4x +x/(4/(7 -5x)) = 5

4x +x(7 -5x)/4 = 5

16x +7x -5x^2 = 20 . . . . . multiply by 4

5x^2 -23x +20 = 0 . . . . . put in standard form

We can use the quadratic formula to solve this.

x = (23±√((-23)² -4(5)(20)))/(2(5)) = (23±√129)/10

x = 2.3 ±√1.29 ≈ {1.1642, 3.4358}

y = 4/(7 -5x) = {3.3930, -0.39297}

Solutions are (x, y) ≈ (1.1642, 3.3930) and (3.4358, -0.39297).

2. a. A fish is 12 meters below the surface of the ocean. What is its elevation?

Alex17521 [72]

Answer:

A. -12 meters

B. 28 meters

C. 40 meters

Step-by-step explanation:

The surface of the ocean would be 0.

Taking this into account, 12 meters below would be 0 - 12, which is -12. Therefore A's elevation would be -12.

For the sea bird, 28 meters above the surface, which is again 0, would be 0 + 28. B's elevation is 28.

Since the fish is 12 meters below the surface and the sea bird is 28 meters above the surface, simply add the two numbers up to get a total of 40 meters. C would be 40 meters.
