Task 1:
laiz [17]

Answer:

The toy's maximum height is 10.12\ \text{feet}.

Step-by-step explanation:

The equation that models the toy's height in feet from the ground at t seconds after  he threw it is given by :

h = -2t^2 + 7t + 4 .....(1)

It is required to find the toy's maximum height. For maxima or minima, put

\dfrac{dh}{dt}=0

Plugging the value of t in above equation,

\dfrac{d(-2t^2 + 7t + 4)}{dt}=0\\\\-4t+7=0\\\\t=\dfrac{7}{4}\\\\t=1.75\ s

Now put t = 1.75 s in equation (1) such that,

h = -2(1.75)^2 + 7(1.75) + 4\\\\h=10.12\ \text{feet}

So, the toy's maximum height is 10.12\ \text{feet}.

Solve: 2 in 3= in (x-4)<br> A: x=9<br> B: x=10<br> C: x=13
Margaret [11]

Answer:

x = 13

Step-by-step explanation:

Please use " ln " for the "natural logarithm," not " in. "

Then you have:    2 ln 3= ln (x-4)

We need to get rid of the " ln " operator.  Rewrite 2 ln 3 as ln 3² = ln (x - 4).

Then 3² = x - 4, or 9 = x - 4, or  x = 13

Select the correct answer. If f(x) = |x| - 4, which translation is applied fo f(x) to get g(x)?
solmaris [256]

Answer:

It is a vertical translation of f(x) four units downward.

Step-by-step explanation:

We are given the original equation f(x) = |x| and the transformed function is g(x) = |x| - 4.

It is clear that the transformed function that g(x) = f(x) - 4.

So, the y-value in g(x) is reduced by 4 units from the y-value of f(x) i.e. the transformation is by 4 units down of function f(x).

Therefore, it is a vertical translation of f(x) four units downward. (Answer)
