Answer:
a)
b)d(t)=500t
c)
Step-by-step explanation:
d = Horizontal distance
s = the distance between the plane and the radar station
The horizontal distance (d), the one mile altitude, and s form a right triangle.
So, use Pythagoras theorem
a)
(b) Express d as a function of the time t (in hours) that the plane has flown.
d(t)=500t
(c) Use composition to express s as a function of t.
using b
Answer:
x = - 
= - 62.5
Step-by-step explanation:
Given
x = - 25
Multiply both sides by 5 to clear the fraction
2x = - 125 ( divide both sides by 2 )
x = - = - 62.5
Answer:
its D
Step-by-step explanation:
Answer:
I'll find X for you; the next step is by you.
Step-by-step explanation:
we have two similar pentagons
I will do it in 2 ways.
1.
=> 48/4x = (x+2)/x
=> 12/x = (x+2)/x
Because of pentagons so x > 0
=> 12 = x + 2 => x = 10
2.
k is unknown number
=> 4x = k.x and 48 = k.(x + 2) (x > 0)
=> k = 4 and 48 = 4.(x + 2)
=> 12 = x + 2 => x = 10
