Hi! Can someone help me get started with these 6 problems, please? Would be a huge help! :D 1. A biologist studied the populations of common guppies and Endler’s guppies over a 6-year period. The biologist modeled the populations, in tens of thousands, with the following polynomials where x is time, in years. Common guppies: 3.22 + 5 + 0.2 Endler’s guppies: 4.42 − 5.1 + 1 What polynomial models the total number of common and Endler’s guppies? 2. A family is building a circular fountain in the backyard. The yard is rectangular and measures 10x by 15x and the fountain is going to be circular with a radius of 4x. Once the fountain is built, what will be the area of the remaining yard? 3. A sports team is building a new stadium on a rectangular lot of land. The lot measures 8x by 12x and the field will be 3x by 6x. How much land will be left for the bleachers, restrooms, and other parts of the stadium? 4. A cylinder has a radius of + 2 and a height of + 4. Which polynomial in standard form best describes the total volume of the cylinder? Use the formula = 2ℎ for the volume of a cylinder. 5. A sphere has a radius of 2 + 3. Write the polynomial in standard form that best describes the total surface area of the sphere? Use the formula = 42 for surface area of a sphere. 6. A carpenter is putting a skylight in a roof. If the roof measures (10x + 9) by (7x + 7) and the skylight measures (x + 5) by (3x + 3), what is the area of the remaining roof after the skylight is built?
