Which solution method did you use? Logarithms Graphing y = 3. 915(1. 106)x and tracing Graphing y = 3. 915(1. 106)x and y = 400, then finding the x-value of the intersection.

Sagot :

The logarithmic properties of a linear system are used to solve the equation.

The x-value of the intersection is x =46.

Linear system;

It is a system of an equation in which the highest power of the variable is always 1.

A one-dimension figure that has no width.

It is a combination of infinite points side by side.

Given

The pond can hold 400 water liters.

[tex]\rm y = 3.915(1.106)x[/tex] is an expression.

Let x be the day and y be the hold of water.

When pond can hold 400 liters of water the x will be;

400 = 3.915(1.106)ˣ

(1.106)ˣ = 400/3.915    

(1.106)ˣ = 102.17

Taking logarithm on both sides, we get

log (1.106)ˣ = log (102.17)

x log (1.106) = log (102.17)                       [log aˣ = x loga] x = [log (102.17)/log (1.106)]    

x = 45.92

x = 46

Thus, the x-value of the intersection is x =46.
