Answer:
1) See figure attached
2)
a) ![d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%28x_2%20-x_1%29%5E2%20%2B%28y_2%20-y_1%29%5E2%7D)
And if we replace we got:
![d = \sqrt{(10 -6)^2 +(15 -9)^2}= 7.211](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%2810%20-6%29%5E2%20%2B%2815%20-9%29%5E2%7D%3D%207.211)
b) ![V = \frac{d}{t}](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
And if we replace we got:
![V = \frac{7.211 ft}{2 sec}=3.606 s](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%7B7.211%20ft%7D%7B2%20sec%7D%3D3.606%20s)
Step-by-step explanation:
Part 1
We can see the plot in the figure attached.
Part 2
a)
For this case we have two points ![(x_1 , y_1) = (6,9) , (x_2 , y_2) = (10,15)](https://tex.z-dn.net/?f=%20%28x_1%20%2C%20y_1%29%20%3D%20%286%2C9%29%20%2C%20%28x_2%20%2C%20y_2%29%20%3D%20%2810%2C15%29)
And we want to find the distance travelled between these two points and we can use the following formula from the euclidian distance between two points:
![d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%28x_2%20-x_1%29%5E2%20%2B%28y_2%20-y_1%29%5E2%7D)
And if we replace we got:
![d = \sqrt{(10 -6)^2 +(15 -9)^2}= 7.211](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%2810%20-6%29%5E2%20%2B%2815%20-9%29%5E2%7D%3D%207.211)
b)
Since it takes two seconds in order to go from (6.9) to (10,15) we can use the definition of velocity:
![V = \frac{d}{t}](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
And if we replace we got:
![V = \frac{7.211 ft}{2 sec}=3.606 s](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%7B7.211%20ft%7D%7B2%20sec%7D%3D3.606%20s)
Answer:
and
(with arrows on top)
Step-by-step explanation:
The sides of any angle are rays. This are half lines, which in your case both start at the point T, and one goes towards point U, while the other one goes from toward point S. So I would write TU (with a little arrow symbol on top). and in the other box I would write TS also with a little arrow symbol on top.
You need to find the perimeter so your units would be feet.
LETTER B
Answer:
22 comic books.
Step-by-step explanation:
(20 - 9) * 2 First subtract 9 from 20
11 * 2 Multiply 11 by 2
22 is the product
Answer:no
Step-by-step explanation:it would not be possible as 8 is a larger number then 3 unless u would be multiplying by decimals which in which case might be possible
