Answer:
A
Step-by-step explanation:
Answer:
It hit the ground at t=2
It reaches its highest point at t=1
Its maximum height =16
Step-by-step explanation:
The graph of the function of the height will be a parapola opening downward where it's x intercepts = the time where the object hit the ground and its maximum point = the point with the maximum point
The x intercepts are 0 when the object was thrown and 2 when it landed
The x coordinate of the vertex is in the middle of the two x intercepts so it will be 1
Substituting the x coordinate of the vertex gives us the y coordinate of the vertex which is the maximum hight 16
Answer: 17x^2 + 11x + 16
Step-by-step explanation:
The first term is, 17x^2 its coefficient is 17 .
The middle term is, +11x its coefficient is 11 .
The last term, "the constant", is +16
Step-1 : Multiply the coefficient of the first term by the constant 17 • 16 = 272
Step-2 : Find two factors of 272 whose sum equals the coefficient of the middle term, which is 11 .
-272 + -1 = -273
-136 + -2 = -138
-68 + -4 = -72
-34 + -8 = -42
-17 + -16 = -33
-16 + -17 = -33
Answer:
x> -12/5
Step-by-step explanation:
Divide both sides (5x and 12) and re write
5x ÷ 5 > -12 ÷ 5
Thus the solution given above
