5/11 in decimal form is .45
Answer:
8
Step-by-step explanation:
a A + b A where A is a matrix and a and b are scalars
( a+b) A
3+5
= 8![\left[\begin{array}{cc}-1&2\\4&-5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-1%262%5C%5C4%26-5%5Cend%7Barray%7D%5Cright%5D)
CF = CD + DF (since D is simply a point on the line, and C to that point added onto F to that point is CF), so 4y-9+2y-7=14. Adding it up, we get 6y-16=14 and adding by 16 we get 30=6y. Dividing both sides by 6, we get y=5. Plugging that into DF, we get 10-7=DF=3
Answer:
Step-by-step explanation:
We have to find a leg, so we have to use the Pythagorean theorem in this way:
![\sqrt{7^2 - 4^2} = \sqrt{49 - 16} = \sqrt{33}](https://tex.z-dn.net/?f=%5Csqrt%7B7%5E2%20-%204%5E2%7D%20%3D%20%5Csqrt%7B49%20-%2016%7D%20%3D%20%5Csqrt%7B33%7D)
