Hope this helped!
In this case we are dealing with the pythagorean theorm involving right angled triangles. This theorm states that a^2 + b^2 = c^2 which means the square of the hypotenuse (side c, opposite the right angle) is equal to the square of the remaining two sides.
In this case we will say that a = 3963 miles which is the radius of the earth. c is equal to the radius of the earth plus the additional altitude of the space station which is 250 miles; therefore, c = 4213 miles. We must now solve for the value b which is equal to how far an astronaut can see to the horizon.
(3963)^2 + b^2 = (4213)^2
b^2 = 2,044,000
b = 1430 miles.
The astronaut can see 1430 miles to the horizon.
18 what is this for exactly..?
I do A and B but that is the way I learned it. Hope this helps :)
Answer:
False
Step-by-step explanation:
10 – [50 ÷ (-2 x 25) -7] x 22 = -18
10 - (50 ÷ (-50)-7) x 22= -18
10 - (-1 - 7) x 22= -18
10 - (-8) x 22 = -18
10 + 8 x 22 = -18
10+176=-18
186=-18
False
