Answer:
12.5 cm
Step-by-step explanation:
The ratio of map distance to ground distance is the same at any distance:
(map distance)/(ground distance) = (5 cm)/(2 km) = (x)/(5 km)
Multiply by 5 km and you have ...
x = (5 cm)(5/2) = 12.5 cm
The ground distance of 5 km is represented by 12.5 cm on the map.
Answer:
B
Step-by-step explanation:
(1 1/2,-2)
solve for x and get 1 1/2
solve for y and get -2
Center of circle is ( 1, 0).
Slope of normal passing though ( 1, 0 ) and ( 2, -5 ) is :

So, slope of tangent will be :

Equation of tangent :

Hence, this is the required solution.
You have the following inequality:

In order to determine which are valid solutions of the previous inequality, take into account that any positive value for V is solution of the previous equation, because if V is positive, 96/V is also positive.
Then, the following area solutions:
V = 3
V = 6
V = 8
V = 4
Domain is X
Range is Y
Therefore {-3,-1,1}
