We are given with the function that expresses the height of the football over time in the equation <span>h(x) = -16t^2 + 64t. To determine the axis of symmetry, we determine the time when it reaches the maximum height. we derive the equation and equate to zero to get t. -32t +64 = 0. t is equal to 2 seconds. Substituting, to the original equation, h(x) is 64. Hence the axis of symmetry is y = 32. </span>
Answer:
Step-by-step explanation:
Yesterday, her rate was 8mph, her time was x hours.
Today, her rate was 13mph, her time was 13 - x hours.
So the total distance she biked on the two days is
d = 8x + 13(13 - x), or 169 - 5x
Answer: Your answer will be (13/52)(12/51)(11/50)
The reason is because each card is not replaced so the number of cards with hearts, as well as the overall card number goes down.
Divide 8/9 by 1/9 to get 8 meters per minute
The answer is D. x+y=4
