Answer:
f = -
Step-by-step explanation:
Given f varies directly with m then the equation relating them is
f = km ← k is the constant of variation
To find k use the condition f = - 19 when m = 14
- 19 = 14k ( divide both sides by 14 )
- = k
f = - m ← equation of variation
When m = 2 , then
f = - × 2 = -
Because the earth is round, the distance seen on a flat map is a lot further than the distance on a globe, because of distortion. So following the circle that goes through these 3 points ( Florida, Alaska and the Philippines) it is a shorter distance to fly over Alaska.
2 log(<em>x</em>) - log(<em>x</em> - 1) = log(<em>x</em> - 2)
log(<em>x</em>²) - log(<em>x</em> - 1) = log(<em>x</em> - 2)
log(<em>x</em>² / (<em>x</em> - 1)) = log(<em>x</em> - 2)
<em>x</em>² / (<em>x</em> - 1) = <em>x </em>- 2
<em>x</em>² = (<em>x</em> - 1) (<em>x</em> - 2)
<em>x</em>² = <em>x</em>² - 3<em>x</em> + 2
0 = -3<em>x</em> + 2
3<em>x</em> = 2
<em>x</em> = 2/3
But notice that 2/3 - 1 = -1/3 < 0, and log(<em>x</em> - 1) is undefined so there are no real solutions.
