(Answer 2,770) (estimation: 3,000)
Answer
28 committees
Explanation:
The total number of members = 8
We want to make a committee of 2 members
We will be applying the combination concept
Therefore, 28 committees can be formed
So the perimeter of the first triangle is 30; since you are given each side you can set up 3 ratios to find the unknown side lengths.
Thus side 5 would correspond to 2.5
Side 12 would correspond to 6
And side 13 would be 6.5
Another way to look at it is that since the perimeter of triangle 2 decreases by half (from 30 to 15), you can assume all side will also decrease by half
(a) Graph equation . Give each axis a label (hours for x, and cost for y) and give the graph a title.
Answer:
D.
Step-by-step explanation:
Let , we proceed to perform all operations described on statement:
1) <em>Dilation</em>
(1)
Where:
- Point of reference.
- Original point.
- Dilated point.
- Scale factor.
If we know that , and , then the dilated point is:
<em>2) Translation</em>
(2)
Where:
- Original point.
- Translation point.
- Translated point.
If we know that and , then the translated vector is:
Therefore, the correct answer is D.
