B. Show how you would use Descartes' Rule for the type and number of solutions of the following polynomial: x^3 - 5x^2 +16x-80

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.

if i knew id you bro,, my bad
