Answer - 11
I’m assuming you’re trying to find the line AB (basically the distance between point A and B). If that’s the case, since they both have the same x vale, subtract their y values. 14-3 gives you 11, which is the length of line AB
Divide both 1 yard and 0.914 meters by 1. 1x = 0.914y
Now, since you want 1 meter = "variable"
1 meter times 1 yard divided by 0.914 meters.
1 meter = 1.094 yards
Answer:
6/4 = 1 1/2
1 2/4
12/8
Step-by-step explanation:
![2cos^2x+5cosx+2=0\\ x\in\\ \Delta=b^2-4ac\\ \Delta=9\\ \sqrt{\Delta}=3\\ cosx=1\\ or\\ cosx=-6\\ -6\notin\\](https://tex.z-dn.net/?f=2cos%5E2x%2B5cosx%2B2%3D0%5C%5C%0Ax%5Cin%3C-1%3B1%3E%5C%5C%0A%5CDelta%3Db%5E2-4ac%5C%5C%0A%5CDelta%3D9%5C%5C%0A%5Csqrt%7B%5CDelta%7D%3D3%5C%5C%0Acosx%3D1%5C%5C%0Aor%5C%5C%0Acosx%3D-6%5C%5C%0A-6%5Cnotin%3C-1%3B1%3E%5C%5C)
Then using trygonometric table or a graph we read that:
![cosx=1\Leftrightarrow(x)=0](https://tex.z-dn.net/?f=cosx%3D1%5CLeftrightarrow%28x%29%3D0)
Period of cosinus function = 2π
So the last answer is
Answer: There are many uses for the variable* y in math: it is often used as a variable and the y axis of a coordinate plane (the line that is vertical.)
* = Variable: any unknown number in algebra, is usually replaced with letters, such as x or y.
