Respuesta :
By basic algebra, we can say that: the satellite to run for about 130 days if it requires 15W of power.
What is basic algebra?
- Numbers, variables, constants, expressions, equations, linear equations, and quadratic equations are all part of the basics of algebra.
- Additionally, the algebraic expressions contain the basic arithmetic operations of addition, subtraction, multiplication, and division.
Given:
- P = 50 [tex]e^{\frac{-t}{250}}[/tex]
- P = Power in watts,
- t = time in days
To find: t when P = 15.
Finding:
On substituting the given values in the given formula, by basic algebra, we get:
15 = 50 [tex]e^{\frac{-t}{250}}[/tex]
=> [tex]\frac{15}{50}=\frac{3}{10}[/tex] = [tex]e^{\frac{-t}{250}}[/tex]
=> log [tex]\frac{3}{10}[/tex] = [tex]\frac{-t}{250}[/tex]
=> - 0.522 = [tex]\frac{-t}{250}[/tex]
=> 130.5 = t
Hence, the satellite to run for about 130 days if it requires 15W of power, as solved by basic algebra.
