An arch has the shape of a semi-ellipse. The arch has a height of 8 feet and a span of 36 feet. Find an equation for the ellipse and use it to find the height, in feet, of the arch at a distance of 2 feet from the center.

anser is a

step-by-step explanation:

negitive slope

thus, the first answer choice, y = sec x, is the correct one

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
