Define the variables in your problem. The elliptical track is centered on the origin. If (x,y) is a point on the ellipse, x describes the distance horizontally from the origin in feet to the point on the ellipse and y describes the distance vertically from the x-axis to the point on the ellipse  in feet .

The length of the major axis is [Fill in the blank], feet. This means that "a" equals [Fill in the blank], in the equation.  The length of the minor axis is [Fill in the blank], feet. This means that "b" equals [Fill in the blank], in the equation. 

Section A: Read the text and answer the questions. Brutalism is an architectural style, introduced in the 1950s. It uses exposed concrete to create geometric structures with a grey appearance. Concrete buildings are often criticised as cold and ugly, lacking the warmth of stone or the smooth feel of steel. However, concrete, as a building material, has unique characteristics. It is extremely flexible when wet, and is adapted to create interesting shapes. Many urban public buildings, such as universities, have also used concrete as the main material to indicate strength and permanence. Instead of keeping Brutalist buildings, many are being demolished to make space for modern styles. However, this does not acknowledge the cultural history of these buildings, and is not sustainable. Fill in the gap with ONE WORD from the paragraph. 1. Brutalist architecture included exposed concrete, which gave a cold Answer Question 1[input] .
