Sheldon also picks tomatoes from his garden. He picked 4 4/10 but 1.5 were rotten and had to be thrown away. How many kilograms
1 answer:
Given:
Number of tomatoes Sheldon picks = kg
Rotten tomatoes = 1.5 kg
To find:
How many kilograms of tomatoes were not rotten?
Solution:
Number of tomatoes Sheldon picks = kg
= kg
= kg
= kg
= kg
Rotten tomatoes = 1.5 kg
Remaining tomatoes which are not rotten is
Required tomatoes = Tomatoes Sheldon picks - Rotten tomatoes
=
= kg
Therefore, the tomatoes which were not rotten is 2.9 kg.

Answer:
Step-by-step explanation:
we're given three points (0,1),(1,0) and (-1,0). and and equation of a parabola
we can plug in each of the coordinates, and 3 equations
(x,y) = (0,1)
(x,y) = (1,0)
(x,y) = (-1,0)
These are are three equations, well we can simultaneously solve them to find the values of a, b and c.
we already found that, a = 1. so we plug this value in the rest of the equations. we'll use equation B.
we can substitute this value of b and a = 1, equation C
we can use this value of c back in b
hence our equation of the 2-degree polynomial will be:
and this polynomial indeed passes through all the points (0, 1), (1, 0), and (-1, 0).
And since these are the only solutions to the simultaneous equation we solved (i.e. we have single values of a,b and c). there's no other possibility.
