The standard distance between bases is 90 feet and the infield is a perfect square.Coach Stevens found one sprinkler that sprays a maximum distance of 50 feet. If Coach Stevens placed the sprinkler on the pitcher's mound, would the water spray so that the entire infield was watered? Justify your response.

(a) Find the coordinates of the centre and the length of the radius for the circle x2 + y2 − 4x − 8y − 5 = 0.

Read the statements carefully and answer the questions as directed.Problem 1:A satellite dish is shaped like a paraboloid. If the dish is 2 meters wide and 0.5 meters deep, find the equation of the parabola representing the shape of the dish.*4 pointsy^2 = 4xx^2 = 2yy = x^2/4x^2 = 4yProblem 2:An artist wants to create a fountain with a circular pool. If the pool has a radius of 6 feet, what is the equation of the circle representing the pool?*4 pointsx^2 + y^2 = 6x^2 + y^2 = 36x^2 - y^2 = 36y = √(36-x^2)Problem 3:A company designs a water slide in the shape of a hyperbola. The distance between the vertices is 10 meters, and the distance between the foci is 8 meters. Find the equation of the hyperbola.*4 pointsx^2/25 - y^2/16 = 1y^2/25 - x^2/16 = 1x^2/16 - y^2/25 = 1y^2/16 - x^2/25 = 1Problem 4:A cylindrical tank has an elliptical base with semi-major and semi-minor axes of lengths 8 feet and 5 feet, respectively. Write the equation of the ellipse representing the tank's base.*4 pointsx^2/64 + y^2/25 = 1x^2/25 + y^2/64 = 1x^2 + y^2 = 64x^2/16 + y^2/9 = 1

Instructions: Use the given information to answer the questions and interpret key features. Use any method of graphing or solving.  Round to one decimal place, if necessary.An irrigation system (sprinkler) has a parabolic pattern. The height, in feet, of the spray of water is given by the equation h(x)=−x2+10x+7.5ℎ(𝑥)=−𝑥2+10𝑥+7.5, where x𝑥 is the number of feet away from the sprinkler head (along the ground) the spray is.The irrigation system is positioned Answer 1 Question 6 feet above the ground to start.The spray reaches a Answer 2 Question 6 height of Answer 3 Question 6 feet at a horizontal distance of Answer 4 Question 6 feet away from the sprinkler head.The spray reaches all the way to the ground at about Answer 5 Question 6 feet away.
