Answer:

Step-by-step explanation:
let distance between farmhouse and road is 2 km
From diagram given
p is the distance between road and past the intersection of highway
By using Pythagoras theorem

differentiate wrt t
we get




putting p = 3.7 km


Answer:
f(x):

g(x)

Step-by-step explanation:
When a function is of the form:

The equation of the axis of symmetry is

The given function is

We can see that h=-4
Hence the equation of axis of symmetry is

From the graph, the axis of symmetry of h(x) is the vertical line that divides the parabola into two congruent halves.
This line is

Answer: opposite sides with equal length
Step-by-step explanation:
Answer:
The slope is 
Step-by-step explanation:
Take the general equation of a straight line 
Here
is the slope of the line.
So let's get the equation of the line in the question in the same form.

Add
to both sides: 
Add
to both sides: 
Divide by
to get it into the general equation: 
Now compare it to the general equation to find the value of
. The value of
is the coefficient of
which we can see is 
So 20=2 itmes m2 times 5
5m=5 times m
so
5m=20
5 times m=2 times 2 times 5
divid eboth sides y 5
m=2 times 2
m=4
