Please answer and solve question 9 parts A,B, and C and show work if you can on how you figured out the number of zeros! Thanks so much!
5. You are competing in the Egg Toss Contest. Your partner tosses the egg to you at an initial velocity of 10 feet per second. You are standing 36 feet away. At what time () does it reach you? The Physies Prof says the formula for the egg flight is D-=-16t2 + vt (D-distance, v-initial velocity) 6. You are surveying a lot shaped like a right triangle. You measure the short leg as x and the longer leg as x+7. The hypotenuse measures 11 feet. How long is the short side? 7. You want to put down hard wood flooring in your den. The room measures 981 square feet. The length is 6 more than the width of the room. What is the width of the room? 8. A rock is tossed off the pier upward at an initial velocity of 14 ft/sec. If the pier is 18 feet above the water, how long does it take the rock to hit the water? H(t)-16t2+ vot + ho (H(t) = height, vo = initial velocity, ho = initial height) 9. How many real zeros would you expect in each of these equations? a. 3x2-5x-7=0 b. 3x2+7x +9-0 c. 4x2-8x + 4-0
