Graph it and you’ll see it’s a line
Answer:
the angle is 40°
Step-by-step explanation:
180 - 140 = 40
The greatest integer function is defined as the greatest integer less than or equal to x.
for example,
[x] = greatest integer less than or equal to x.
[3.5] = 3
[-3.6] = -4 (because -4 is less than -3.6)
[-5]=-5
[12]=12
[ π ] = 3
[ π /2 ] = [ 1.57 ] = 1
[ π ] /2 = 3/2 = 1.5
[[ π ] /2 ] = [ 1.5 ] = 1
etc.
It is also called the floor function.
Answer:
C
Step-by-step explanation:
For the first problem, we use the trigonometric function cosine. The equation would be:
cos (1/2)θ = 3960 / (3960 + 90)
Solving for θ
θ = 24.20°
Solving for the distance the satellite can see:
s = rθ
s = 3960 (24.20) π/180
s = 1672.79 mi
The satellite can see1672.79 mi of distance.
For the second problem, we approach the reverse manner as the first problem.
Solving for the angle,
θ = s/r
θ = 3000 / 3960
θ = 0.7576 (180/π) = 43.41°
Solving for h:
cos 1/2 (43.41) = 3960 / (3960 + h)
h = 302.19 mi
The satellite must be 302.19 mi above the Earth.
