The speed of the satellite is v = √(Gmp/r)
At the geostationary orbit, the gravitational force of attraction of the planet on the satellite equals the centripetal force on the satellite.
Let F = gravitational force
where G = universal gravitational constant, mp = mass of the planet, m = mass of satellite and r = radius of geostationary orbit.
Also, the centripetal force F'
where m = mass of satellite, v = speed of satellite and r = radius of geostationary orbit.
Since both forces are equal,
F = F'
So, the speed of the satellite is v = √(Gmp/r)

Answer:
d = 9
Step-by-step explanation:
200% = double
aka 2d = 18
d = 9
Min at (2,-4)
D=1-4*1*-6=25=> 2 real roots
x=3, -2
Answer: 36
Step-by-step explanation:
The legs are given to be :
3x - 1 and -x + 27
The base = 5x + 1
One of the properties of an isosceles triangle is that two sides are equal , that is the two legs are equal. This means that
3x - 1 = - x + 27
3x + x = 27 + 1
4x = 28
x = 7
To calculate the length of the base, substitute x = 7 into the length of the base given , that is
Length of the base = 5(7) + 1
L = 35 + 1
L = 36
Answer: 0.42 and 5 outcomes.
Step-by-step explanation:
i guess that carlos has a fair coin and a number cube.
the probability can be calculated as the number of outcomes that we want divided the total number of outcomes.
The coin has two possible outcomes, heads and tails, then the probability of getting heads is p1 =1/2
the number cube has 6 numbers, 5 of those 6 numbers are greater than 1, then the probability of getting a number greater than 1 is p2 =5/6
the joint probability is the product of those two:
P = 1/2*5/6 = 5/12 = 0.42
The combinations that include heads and number greater than 1 are 5 combinations:
Heads and 2
Heads and 3
Heads and 4
Heads and 5
Heads and 6.
