Answer:
√28 = 2√7
√40 = 2√10
√108 = 6√3
√125 = 5√5
-6√81 = -54
√80 = 4√5
3√60 = 6√15
-√200 = -10√2
4√320 = 32√5
Step-by-step explanation:
1. The largest factor that's a square in 28 is 4, so the other factor must be 7.
2. The largest factor that's a square in 40 is 4, so the other factor must be 10.
3. The largest factor that's a square in 108 is 36, so the other factor must be 3.
4. The largest factor that's a square in 125 is 25, so the other factor must be 5.
5. The square root of 81 is 9, and 9 times -6 is -54.
6. The largest factor that's a square in 80 is 16, so the other factor must be 5.
7. 3√60 is equivalent to √540 (because 60 x 9 = 540). The largest factor that's a square in 540 is 36, so the other factor must be 15.
8. The largest factor that's a square in 200 is 100, so the other factor must be 2.
9. 4√320 is equivalent to 5120 (because 320 x 16 equal 5120). The largest factor that's a square in 5120 is 1024, so the other factor must be 5.
Answer:
an = -39 -100(n -1)
Step-by-step explanation:
The given sequence can be described by a 3rd degree polynomial.* However, we suspect a typo, and that your intention is to have a formula for the arithmetic sequence ...
-39, -139, -239, -339
This has a first term a1 = -39, and a common difference d = -100.
The model for the explicit formula is ...
an = a1 +d(n -1)
Filling in the given values, the formula you seek is ...
an = -39 -100(n -1)
_____
* That polynomial is ...
an = 50n^3 +350n^2 -800n +461
This gives a sequence that starts ...
-39, -139, -139, -339, -1039, -2539, -5139, -9139, ...
Answer:
h(x) = g(x+5) + 1
Step-by-step explanation:
to shift a graph to the right by , the formula is (x-a), here we need to shift by a = 5. Here, we need to move g(x) to the left so a = -5.
To move the graph up by 1 square, add 1 from the result of g(x)
