Hii friends help me to do my homework
the zeroes of 3x² - 2x + 1/3 are real and equal justify

Step-by-step explanation:

Proof using Discrimant:

The discrimant is

B is -2, A is 3 and C is 1/3 so we get

Since the discrimant equal zero, there is one real distinct zero.

This zero will also have a multiplicity of 2, so the zero is technically equal to each other.

To get better at solving, let solve for zero.

That zero is 1/3,1/3

The answer is in the image 

The answer is in the image 

The solution is in the following image

The answer is in the image 

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

The answer is in the image 

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
