The function g(t)=−16t2+vt+h represents the height of an object, g, in feet, above the ground in relation to the time, t, in sec

kow [346]

Answer:

A) g(t) = - 16*t² + 80*t

B) domain is ( 0 ≤ t ≤ 5 )

Step-by-step explanation:

A) for the model rocket

h = 0 and v = 80 feet/sec

Then the equation g(t) = -16*t² + v*t + h

became

g(t) = - 16*t² + 80*t + 0 g(t) = - 16*t² + 80*t

B) The equation g(t) = - 16*t² + 80*t is defined for all real numbers then the domain interval for t is ( -∞ , ∞ ). Now in our case, a model rocket was launched is not possible to get negative values for g(t) then the biggest value for t = 5 from

-16*t² + 80*t ≥ 0

-16*t ≥ -80 16*t ≤ 80

t ≤ 5

And the domain is ( 0 ≤ t ≤ 5 )

Find the indicated limit, if it exists. (2 points) limit of f of x as x approaches 5 where f of x equals 5 minus x when x is les

Tamiku [17]

It looks like we have

$f(x)=\begin{cases}5-x&\text{for }x5\end{cases}$

and we want to find $\lim\limits_{x\to5}f(x)$ .

Since $x$ is approaching 5, we don't care about the value of $f(x)$ when $x=5$ .

We do care about how $f(x)$ behaves to either side of $x=5$ . If $x\to5$ from below, then $f(x)=5-x$ , so that

$\displaystyle\lim_{x\to5^-}f(x)=\lim_{x\to5}(5-x)=5-5=0$

On the other hand, if $x\to5$ from above, then $f(x)=x+3$ , so that

$\displaystyle\lim_{x\to5^+}f(x)=\lim_{x\to5}(x+3)=5+3=8$

The one-sided limits do not match, since 0 ≠ 8, so the limit does not exist.
