Answer:
a=4
Step-by-step explanation:
We can see that 64= 4*4*4= 4^3, replacing 64 with 4^3 in the equation:
A. In 8,326, the 8 is in the thousands place, while in 840,210, the 8 is in the hundred-thousands place.
B. In 2,008, the 8 is in the ones place, while in 28,420, the 8 is in the thousands place.
C. In 284, the 8 is in the tens place, while in 32.098, the 8 is in the thousandths place.
D. In 48.97, the 8 is in the ones place, while in 32.80, the 8 is in the tenths place.
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>
