1. samuel bought a cement mixer for $54,205. the value of the cement mixer depreciated at a constant rate per year. the table below shows the value of the cement mixer after the first and second years: year 1 2 value (in dollars) 47,158.35 41,027.76 which function best represents the value of the cement mixer after t years? f(t) = 47,158.35(0.87)^t f(t) = 54,205(0.13)^t f(t) = 47,158.35(0.13)^t f(t) = 54,205(0.87)^t

Step-by-step explanation:

Given: The initial value of cement mixer (A) = $54,205

After one year, the value of mixer = $47,158.35

The constant rate of depreciation (b)=

The exponential function represent the value after depreciation of t years is given by :-

Hence, the function best represents the value of the cement mixer after t years will be

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

i think da answer is

d.square root of 3
