Step-by-step explanation:
Given
Required
Determine the scale factor of RST
The question can be solved using scale factor formula
Scale factor is calculated as thus;
In this case; R' is the new length and R is the old length
Substitute the values of R and R'
Factorize the denominator
<em>Hence, the scale factor used is 0.4</em>
Answer:
7
Step-by-step explanation:
See the attached diagram with this answer.
If two straight lines cross a circle intersecting at two points then they can form a maximum of 4 regions within the circle, like the straight lines pq and rs form in circle c.
Now, another straight line mn is so placed that it forms the maximum number of separate regions in the circle.
Therefore, from the diagram, it is clear that there may be a maximum 7 separate regions formed by three straight lines intersecting the circle at two distinct points. (Answer)
