Answer:
5461
Step-by-step explanation:
You can recognize this as the sum of 7 terms of a geometric series with first term 1 and common ratio 4.
That sum is given by ...
where a1 is the first term and r is the common ratio.
Filling in the numbers, we have ...
The sum is 5461.
Answer:
D
Step-by-step explanation:
Let's see if the lengths of these two segments are the same or not. We will use the distance formula, which says that for two points and , the distance between them is: .
For AB, is (-9, 12) and is (3, -6). So, the distance is:
For A'B', is (-3, 4) and is (1, -2). So, the distance is:
We can see that is 3 times of , which means that AB (the original) is 3 times the length of A'B' (the transformed).
Since the length has changed, we know that it must be some sort of dilation because that's the only kind of transformation that will change the length. We see that the segment has also shortened, which means that its scale factor must be less than 1.
The only answer that matches is D.
Hope this helps!
2x + 2y = 20
2(6) + 2y = 20
12 + 2y = 20
2y = 8
y = 4
width = 4
Area = 6 × 4
= 24 cm
