A) Who would not love birdies??
Answer:![(x_1,y_1)=(1,-2)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%3D%281%2C-2%29)
![(x_2,y_2)=(-8,-2)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%3D%28-8%2C-2%29)
Step-by-step explanation:
Given
Co ordinates of vertices(1,-6) and (-8,-6)
When two points is given then Length of two points is given by
![L=\sqrt{\left ( x_2-x_1\right )^2+\left ( y_2-y_1\right )^2}](https://tex.z-dn.net/?f=L%3D%5Csqrt%7B%5Cleft%20%28%20x_2-x_1%5Cright%20%29%5E2%2B%5Cleft%20%28%20y_2-y_1%5Cright%20%29%5E2%7D)
![L=\sqrt{\left ( 1-\left ( -8\right )\right )^2+\left ( -6+6\right )^2}](https://tex.z-dn.net/?f=L%3D%5Csqrt%7B%5Cleft%20%28%201-%5Cleft%20%28%20-8%5Cright%20%29%5Cright%20%29%5E2%2B%5Cleft%20%28%20-6%2B6%5Cright%20%29%5E2%7D)
![L=\sqrt{9^2}=9 units](https://tex.z-dn.net/?f=L%3D%5Csqrt%7B9%5E2%7D%3D9%20units)
Perimeter of rectangle is =26 units
Let the other side be x
thus
![2\left ( x+9\right )=26](https://tex.z-dn.net/?f=2%5Cleft%20%28%20x%2B9%5Cright%20%29%3D26)
x+9=13
x=4 units
therefore to get the other two co ordinates
such that the length of that side is 4 units is
![(x_1,y_1)=(1,-2)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%3D%281%2C-2%29)
![(x_2,y_2)=(-8,-2)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%3D%28-8%2C-2%29)
Horizontal distance will remain same only vertical distance will change in given co ordinates to obtain the remaining two co ordinates
To verify the above two distance between two points must be 13 units
Answer:
its B.
Step-by-step explanation:
all you have to do is y divided by x to find the constant of proportionality
so it would be two y=2x
First off, the underline underneath means plus or minus, since when you take the square root of something, the answer can be negative or positive at the same time
1. 64 is a perfect square. 8 x 8 = 64, therefore it is +- (plus or minus) 8.
2. 45 is not a perfect square, so you can pull out numbers or plug into a calculator and estimate.
Both answers: Since 45 is divisible by 9 and five, you can break a nine into two threes, therefore pull it out, and since the answer is negative, you get:
-3(5)^0.5 (an exponent of one-half or 0.5 means square root)
If you solve by calculator, the answer is ~= (approximately equal to) -6.72
3. Since 90 is not a perfect square, repeat the previous question. 9 can go into 90, therefore you can pull out two threes and are left with: +-3(10)^0.5
Using the calculator, you get ~= +-9.49
