What is the equation of the asymptote? f (x) = 3^x-5+1<br> y=?

Natasha_Volkova [10]

The equation of the asymptote is $y=1$

Explanation:

The given equation is $f(x)=3^{x-5}+1$

We need to determine the horizontal asymptote of the equation.

The given equation is of the exponential function of the form $f(x)=c \cdot n^{a x+b}+k$ and has a horizontal asymptote $y=k$

Hence, from the above equation, the value of k is 1.

Therefore, we have,

$k=1$

Thus, the horizontal asymptote is $y=1$

Therefore, the asymptote of the equation is $y=1$

A ball travels on a parabolic path in which the height (in feet) is given by the expression $-25t^2+75t+24$, where $t$ is the ti

evablogger [386]

Answer:

The height of the ball is at it's maximum 1.5 units of time after launch.

Step-by-step explanation:

Suppose we have a quadratic function in the following format:

$h(t) = at^{2} + bt + c$

If t is negative, the maximu value of h(t) will happen at the point

$t_{MAX} = -\frac{b}{2a}$

In this question:

$h(t) = -25t^{2} + 75t + 24$

$a = -25, b = 75, c = 24$

Then

$t_{MAX} = -\frac{b}{2a} = -\frac{75}{2*(-25)} = 1.5$

The height of the ball is at it's maximum 1.5 units of time after launch.
