Answer:
AB=5.83
Step-by-step explanation:
Distance Formula=
Plugging our values in, we get:
And if we solve it like this:
We end up with:
Which is about 5.83
Answer:
No
Step-by-step explanation:
If you draw a line, it will not go through the origin and there isn't a constant rate of change.
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:
1.
Part A: Yes, it is (a - b)².
Part B: a² - 2ab + b² => (x - 6)² = x² - 12x + 36.
Part C: x² - 12x + 36.
2.
Part A: Not a special product.
Part B: Binomial distribution => (x + 8)(x + 1) = x² + 9x + 8.
Part C: x² + 9x + 8.
3.
Part A: Yes, it is (a + b)²
Part B: a² + 2ab + b² => (3x + 2)² = 9x² + 12x + 4.
Part C: 9x² + 12x + 4.
4.
Part A: Yes, it is (a + b)(a - b), a difference of squares.
Part B: a² - b² => 4x² - 49
Part C: 4x² - 49.
5.
Part A: Not a special product.
Part B: Binomial distribution => (x - 5)(2x - 5) = 2x² - 15x + 25.
Part C: 2x² - 15x + 25.
