Taylor is building a rectangular garden. Due to the space available, the area of the A (in square feet), can be expressed by the function A garden, where W represents the width of the garden (in feet). = w(75 - w), Based on this function, the width of the garden must be more than A feet wide and less than A feet wide.

Red aerial mini-flares are used by some boaters in an emergency. The flight of one brand of flare, when fired at an angle of 70° to the horizontal is modelled by the function h = -9t^2 + 72t + 2, where h is the height, in metres and t is the time, in seconds, since the flare was fired. Write an equation in the standard form. What is the maximum height of the flare?

cameron launches a toy plane from the roof of the school building, which is 84 feet high. the plane height above the ground is modeled by the function h=-16t^2+32t+84. how high does the plane get to the air ?

Suppose a company sells kids bicycles. The company's profit can be represented by the function P = x2 +3x -5250, where x is the number of bikes sold. If the company sells 150 bicycles, what is the company's profit?

The area of a rectangle can be explained by the function A (x) = 8x + 20x . Give two different possible combinations of length and width of the rectangle.

Suppose that a ball is thrown from the top of a 44-foot building. The function h(t) = - 16t2 + 80t +44 models the height in feet, h, of the ball t seconds after it is thrown. a) When does the ball hit the ground? The ball hits the ground after seconds b) Find the time(s) the ball will be 108 feet above ground. You may use fractions or decimals. Use a comma to separate values, if necessary} The ball is 108 feet above ground after seconds O c) The ball will be at its highest point after t = 2.5 seconds. Find the height of the ball at that time. The height of the ball after 2.5 seconds is feet
