120 seconds
1 min = 60 seconds
Step-by-step explanation:
log x = 1 + a
a = log x - 1
log y = 1 - a
a = 1 - log y
So
log x - 1 = 1 - log y
log x + log y = 2
log (xy) = 2
xy = 100
Answer:
2, 
Step-by-step explanation:
Given parameters:
Coordinates = (5,1) and (-1,4)
Unknown:
The midpoint = ?
Solution:
To find the midpoint of these endpoints;
this can be mathematically expressed as;
x
, y
= 
From the given coordinates;
x₁ = 5 y₁ = 1
x₂ = -1 y₂ = 4
x
, y
=
,
= 2,
