An automobile is driven on a straight road, and the distance traveled by the automobile after time t=0 is given by a quadratic f
KengaRu [80]

Answer:

See Explanation

Explanation:

The question is incomplete as the value of s(t) is missing;

However, the following explanation will guide you;

I'll continue my explanation with the following assumption that:

s(t) = 64 + 4(t-6)

Required

Determine the velocity at t = 8

To do this; first calculate s(t) by substituting 8 for t in s(t) = 64 + 4(t-6)

s(8) = 64 + 4(8- 6)

s(8) = 64 + 4(2)

s(8) = 64 + 8

s(8) = 72

Next, is to calculate the velocity by dividing s(t) by t where t = 8

i.e.

Velocity = \frac{s(t)}{t}

Substitute 8 for t

Velocity = \frac{s(8)}{8}

Substitute 72 for s(8)

Velocity = \frac{72}{8}

Velocity = 9\ ft/s

<em>So: all you need to do is first calculate s(8), then divide the resulting value by 8 to get your result</em>

Why is corn in so much of our food today
prisoha [69]

Answer:

"Why we grow so much corn (about 87 million acres each year) is because we can. ... Anti-ethanol advocates also like to pick on corn. They thrust with a two pronged argument: that too much good food producing corn is being used for fuel, and that ethanol is driving up the cost of corn and, thus, food."
