Answer:
-20.2m -11.8
Step-by-step explanation:
(2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)
Distribute the minus sign
(2y + 14.6m + 3.8) – 34.8m - 15.6 - 2y
I like to line them up vertically
2y + 14.6m + 3.8
– 2y -34.8m - 15.6
------------------------------
-20.2m -11.8
Out of the total 60 students 18 take Algebra 1 and 20 take Algebra II. 10 take both. So out of the 18 taking algebra 10 are taking Algebra II. If we don't count that 10 because they are already counted in Algebra II count. So 28 students are taking either course. Therefore 60-28 = 32 students who are not taking either of these courses
To answer this, we need to start with the standard equation for an ellipse:
(x^2/a^2)+(y^2/b^2)=1
Where a is one half of one axis, and b is one half of the other.
The problem states that one axis is 1057 ft, and the other is 880 ft, so divide these values by 2 and square them. This results in:
(x^2/279,312.25)+(y^2/193,600)=1
For verification, if you have a graphing calculator, solve for y, set the size of the window so it should perfectly fit the ellipse, and check (it does)
We need a picture or something but this is what a right triangle looks like. It will have a square or a 90 degree angle
