Here is a scale drawing of a garden. Kim wants to plant a tree in the garden according to the following rules: It must be 7 m from A and 4 m from C. Place a cross where Kim can plant the tree.

On the scale drawing of the garden, the point to plant the tree is 3.5cm from point A and 2cm from point C

The scale factor is given as: 1 cm represents 2 m

From the question, we understand that the point to plant the tree is 7m from point A and 4 m from point C

Using the scale factor, the location of the point is calculated as follows:

This means that the point is 3.5cm from point A and 2cm from point C

If the scale is 1 or more cm to every meter you can count 7 from A

if it is 2cm to every meter you can count 6cm and count this as 3 meter so that when you extend another 6cm you have 3m +3m = 6 meters it would just be 2 more cm to count for 1 m  to equal it has 7m.

Repeat for 4m for C which is 4 groups of cm depending what the scale is.

The two should meet at a cross the same as counting one direction from 7 and counting across for 4 in another direction.

Step-by-step explanation:

x = -2

y = 848

step-by-step explanation:

plug in the numbers

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
