3. Russell Wilson is famous for his long deep passes during a Seahawks game. This image is taken from week 2 of our current season when Wilson threw to Lockett for an 80-yard touchdown. On the field below I have drawn the approximate path of the ball in that game and coordinates of some points on the graph of the parabola it formed. According to DESMOS, the equation that will describe the path of the ball shown is approximately...

y = -0.029x2 - 0.324x + 14

A. Use the Quadratic Formula and a calculator to solve the equation. Your answers should show that x is approximately -28 or 17. 4 points Show all work here.

How do the number line graphs of the solutions sets of -23 > x and x-23 differ?

If 7x=9y, y/z = 7/5 , then x/z = (a) 2/7 (b) 7/9 (c) 9/5 (d) 9/7 (e) 5/9

Submarines control how much they float or sink in the ocean by changing the volume of air and water contained in large ballast tanks. when the tanks are completely full of water, the submarine increases its overall mass and sinks down to the bottom. when the tanks are completely full of air, the submarine reduces its overall mass and floats to the surface. depending on the density of the seawater surrounding the submarine, it will pump seawater in or out of the tanks in order to achieve the same overall density as the sea water and float neutrally in the water. the volume of the submarine never changes. when the tanks are completely full of water, a submarine with a volume of 7.8\times10^3\text{ m}^37.8×10 3 m 3 7, point, 8, times, 10, start superscript, 3, end superscript, space, m, start superscript, 3, end superscript has a total mass of 8\times10^6\text{ kg}8×10 6 kg8, times, 10, start superscript, 6, end superscript, space, k, g. the density of the seawater is 10^3\text{ kg/m}^310 3 kg/m 3 10, start superscript, 3, end superscript, space, k, g, slash, m, start superscript, 3, end superscript. to make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that submarine need to subtract from its tanks?
