initially, there were only 86 weeds in the garden. the weeds grew at a rate of 29% each week. the following function represents the weekly weed growth: f(x) = 86(1.29). rewrite the function to show how quickly the weeds grow each day.
a. f(x) = 86(1.04)*; grows approximately at a rate of 0.4% daily
b. f(x) = 86(1.04)7%, grows approximately at a rate of 4% daily
c. f(x) = 86(1.29)7%; grows approximately at a rate of 20% daily
d. f(x) = 86(1.297); grows approximately at a rate of 2% daily

Option A. ; grows approximately at a rate of 0.4% daily

Step-by-step explanation:

we have

where

f(x) the number of weeds in the garden

x ----> the number of weeks

Calculate how quickly the weeds grow each day

Remember that a week is equal to seven days

so

Using the law of exponents

b^(x/a) = b^(x*(1/a)) = (b^(1/a))^x

so

therefore

The rate is approximately

1.04=1+r

r=1.04-1=0.04=4% daily

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

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.
