Answer:
Rule: dilation about the origin by a scale factor of 2
Step-by-step explanation:
Given
See attachment for QRST and Q'R'S'T
Required
The dilation rule
First, we calculate the scale factor (k)
From the attachment, we have:
k, is then calculated as:
<em>Hence, QRST is dilated by a factor of 2</em>
Answer:
Step-by-step explanation:
10^0=1 so 1.64*1=1.64
10^2=10*10=100 so 2*100=200
1.64/200=0.0082
Answer:
The length of the diameter of this circular area is of 30 miles.
Step-by-step explanation:
The area of a circular region can be represented by the following equation:

In which r is the radius. The diameter is twice the radius.
In this question:

So




The radius is a positive measure, so

Area in squared miles, so the radius in miles.
What is the approximate length of the diameter of this circular area
D = 2r = 2*15 = 30 miles
The length of the diameter of this circular area is of 30 miles.
