If you flip over the x-axis A' would be (1, -1) (just change the sign on the x)
Then rotate 180 reverse the points to get A'' at (-1, 1)

I need this question 2!
Step-by-step explanation: can someone please answer this.
Answer:
559.70 ft
Step-by-step explanation:
Let D be the distance between building and Bianca.
Height of building H = 150 ft
Let there be a triangle ABC where, AC = height of building H= 150ft, AB = distance between Alice and Bianca and BC = D and therefore, ∠ABC = 15°.
Now in Triangle ABC , tanB = AC/BC
therefore, tan15° = 150/D
D = 150/tan15° = 559.70 ft
Therefore, the distance between building and Bianca D = 559.70 ft
Answer:
285 (or 30% of 950)
Step-by-step explanation:
It might help if you think of it in terms of 10% and 1%. 10% is the same as dividing by 10. so 10% of 45 is 45. 1% is dividing by 100, so 10% of 55 is .55
Now, it also asks what is the amount that don't fir into the 30% and 40% of the books we know. Well, that means we want to know the remaining 30%. It's 30% history, 40% science and 30% other to make 100%.
So what is 30% of 950? You could just multiply 950 by 30% or .3, or you could do the method I mentioned. What is 10%? 95. Then you multiply that by 3 to get 30%. so 30% of 950 is 285
Answer:
A = 328 units^2
Step-by-step explanation:
Here two sides are parallel: 19 and 22. Their average is 41/2.
The width of the trapezoid is 16.
Thus, the area of the trapezoid is A = (41/2)(16), or A = 328 This matches the first answer choice.
