Answer:
x = 5
x = 0.5
Step-by-step explanation:
2x2 - 11x + 5 = 0
Roots: 5, 0.5
Root Pair: 11/4 ± 9/4
Factored: f(x) = 2(x - 5)(x - 0.5)
The first one is 2x^2+2x-2
the second one is 2x^2-2x-2
the third one is 6h+6k
To do this you want to divide 110 by 5 to get 22. Now you want to multiply 3 by 22. That means the caterer need 66 pounds of tomatoes.
7400 grams is the answer.
• The ball is at the same height as the building between 8 and 10 seconds after it is thrown. TRUE - the height is zero somewhere in that interval, hence the ball is the same height from which it was thrown, the height of the roof of the building.
• The height of the ball decreases and then increases. FALSE - at t=2, the height is greater than at t=0.
• The ball reaches its maximum height about 4 seconds after it is thrown. TRUE - the largest number in the table corresponds to t=4.
• The ball hits the ground between 8 and 10 seconds after it is thrown. FALSE - see statement 1.
• The height of the building is 81.6 meters. FALSE - the maximum height above the building is 81.6 meters. Since the ball continues its travel to a distance 225.6 meters below the roof of the building, the building is at least that high.
