If anyone could help out with this one i would really appreciate it <br><br> f(2)=?
algol13

Answer:

f(2) = 0

Step-by-step explanation:

Function f(t) is defined in three different ways depending on the value of t.

For t = 8, function f(t) is -64/t.

For t = 10, function f(t) is 14 - t.

We are not asked about f(8) or f(10). We are asked about f(2). The third definition of function f(t) is for all values of t that are not 8 or 10. 2 is not 8 or 10, so use the third definition of function f(t) and plug in 2 for t.

f(t) = t^2 - 3t + 2 for t not equal to 8 or 10.

f(2) = 2^2 - 3(2) + 2

f(2) = 4 - 6 + 2

f(2) = 0

Divide 28 cans into 2 groups so the ratio is 3 to 4
zysi [14]
\bf \cfrac{\textit{first group}}{\textit{second group}}\qquad 3:4\qquad \cfrac{3}{4}\implies \cfrac{3\cdot \frac{28}{3+4}}{4\cdot \frac{28}{3+4}}\implies \cfrac{3\cdot \frac{28}{7}}{4\cdot \frac{28}{7}}\implies \cfrac{12}{16}

Simplify the fraction 4t ^ 2 - 16 ÷8 ÷ t - 2 ÷6
Sedaia [141]

4t ^ 2 - 16 ÷8 ÷ t - 2 ÷6

=(4t ^ 2)-(16 ÷8 ÷ t)-(2 ÷6)

=(4t ^ 2)-(2/t)-1/3

=4t ^ 2-2/t-1/3

The distance that an object falls from rest, when air resistance is negligible, varies directly as the square of the time that i
eimsori [14]

Since the distance varies directly as the square of time, then its expression looks like this:

d\text{ = k}\cdot t^2

Where d is the distance, "k" is the proportionality constant and t is the time the object is falling. We know that after 6 seconds the stone travels 304 feet. With this information we can determine the value of "k".

\begin{gathered} 304=k\cdot(6)^2 \\ 304=k\cdot36 \\ k=\frac{304}{36} \\ k=8.44 \end{gathered}

Therefore the complete expression is:

d=8.44\cdot t^2

We want to know the distance after 7 seconds, therefore t = 7.

\begin{gathered} d=8.44\cdot(7)^2 \\ d=8.44\cdot49=413.56\text{ feet} \end{gathered}

The stone will travell approximatelly 314 feet in 7 seconds.
