1. (a) The orbital period can be calculated using the equation
T = 2πrr r
gR2
e
where r = Re + h
where re = 6378 km is the earth’s radius, r is the satellites distance
from the earth’s center and h = 205 km is the satellite’s orbital altitude, and g = 9.81m/s2
is the gravitational acceleration. With these
given values the orbital period is
Torbit = 5312.5s = 1.4757h
Answer:

Complete question :
Merlin wants to make more money selling fake beards this month than he did last month. All black beards in his shop cost the same amount of money, and all red beards in his shop cost $25. Let B represent the number of black beards and R represent the number of red beards that Merlin can sell to make more money than he made last month. 20B+25R > 350 According to the inequality, how much money did Merlin make last month, and how much does each black beard cost?
Answer:
1.) > 350
2.) $20
Step-by-step explanation:
Number of black beard = B
Number red beard = R
Cost of red beard = 25
Last month inequality :
20B+25R > 350
Amount Merlin made last month :
Revenue from both red and black Bearf, Hence amount realized last year greater than 350
Cost per black beard is the Coefficient of B which is 20
