The equatorial radius of the planet Mars:
r = 3.396 km
An arc of the planet that is visible to a camera in a satellite:
cos Ф/2 = r / ( r + 12,000 ) = 3.396 / ( 3,396 + 12,000 ) =
= 3,396 : 15,396 = 0.22
Ф/ 2 = cos^(-1) 0.22 = 77.3°
Ф = 2 · 77.3° = 154.6°
Answer: 154° 36

Answer:
<h3>A (-4,3)</h3>
Step-by-step explanation:
THe formula for calculating midpoint is expressed as;
M(X, Y) = {(x1+x2/2), y1+y2/2}
Given
Midpoint = (2, 5)
K = (8, 7)
Required
Coordinate of M
X = x1+x2/2
2 = 8+x2/2
4 = 8+x2
x2 = 4-8
x2 = -4
Similarly;
Y = y1+y2/2
5 = 7+y2/2
10 = 7+y2
y2 = 10-7
y2 = 3
Hence the coordidates of M is at (-4,3)
Answer:
8000/531441
Step-by-step explanation:
With 25 men and 20 women that means there are 45 people in total. This means the ratio of men to total is 25:45 which we can reduce to 5:9 which means there is a 5/9 chance we would pick a man if we just chose one person. The ratio of women to total is 20:45 which we can reduce to 4:9 meaning there is a 4/9 chance we would pick a women if we just choice one person. When finding probability of multiply things happening we multiply and because this situation is with replacement. So we will multiply
(5/9)(4/9)(4/9)(4/9)(5/9)(5/9)=8000/531441
I hope this helps and please don't hesitate to ask if there is anything still unclear!
