Answer:
At any given moment, the red ant's coordinates may be written as (a, a) where a > 0. The red ant's distance from the anthill is
. The black ant's coordinates may be written as (-a, -a) and the black ant's distance from the anthill is
. This shows that at any given moment, both ants are
units from the anthill.
Step-by-step explanation:
Given:
red ant's coordinates written as (a,a)
black ant's coordinates are written as (-a, -a)
To find:
The distance of red and black ants from anthill
Solution:
Compute the distance of red ant from the anthill using distance formula
d (red ant) = 
= 
= 
=
So distance of red ant from anthill is
Compute the distance of black ant from the anthill using distance formula
d (black ant) = 
= 
= 
= 
=
So distance of black ant from anthill is
Hence both ants are
units from the anthill.
Answer:
1120
Step-by-step explanation:
40% of 2800
= 40/100 × 2800
= 4/10 × 28
= 112/10
= 11.2 × 100
= 1120
Answer:
Step-by-step explanation:
(2x-5)(x+6)=0
either 2x-5=0 Or, x+6=0
2x-5=0
2x=0+5
x=5/2
x+6=0
x=0-6
x=-6
so x=5/2 , x=-6
