Answer:
Step-by-step explanation:
Simple interest = 
End of first year = 650+19.5 = $669.50
End of second year = 669.50+19.5 = $ 689
End of third year = 689+19.5 = $708.50
End of fourth year = 708.50 +19.5 = $ 728
End of fifth year = 728 +19.5 = $747.50
The equation would be L = 1d + 45
After 21 days it would be
L = 1(21) +45
L = 21 + 45
L = 66 miles after 21 days
A function assigns the values. The absolute magnitude of a star that has a period of 62 days is -6.3328.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
The relationship between the brightness of a Cepheid star and its period, or length of its pulse, is given by
M = − 2.78 (log P) − 1.35,
Given the absolute magnitude of a star that has a period of 62 days is,
M = − 2.78 (log 62) − 1.35
M = -6.3328
Hence, the absolute magnitude of a star that has a period of 62 days is -6.3328.
