The math teacher gives each student a map of the amusement park that use a coordinate plane the meeting locates is at(0,0) on th
GrogVix [38]

Given:

Starting point = (0,0)

First ride = (0,4)

Second ride = (3,0)

In map, each unit = 100 ft

To find:

The actual distance between first and second ride.

Solution:

Distance formula: Distance between two points is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using the distance formula, we get the distance between first ride and second ride in the map is

d=\sqrt{(3-0)^2+(0-4)^2}

d=\sqrt{9+16}

d=\sqrt{25}

d=5

So, the distance between first ride and second ride in the map is 5 units.

We have,

1 units  = 100 ft

5 units = 500 ft

The actual distance between first and second ride is 500 ft.

Therefore, the correct option is C.

How do we know that the derivative of 1/x is equal to -1/x^2 ?
snow_lady [41]

Answer:the derivative of 1/x =-1/x^2

Step-by-step explanation:

1/x can also be written as x^-1

Therefore d/dx of x^-1

=-1*x^-1-1

=-1x^-2

Which can also be written as -1/x^2

Note: d/dx also means derivative of x

And d/dx (a/x^b) =(a*-b) /x^(b+1)

Where a and b represents a variable
