Hello, I need help with a calculus FRQ. My teacher has given a hint that this last part has to do with the intermediate value th

lesya [120]

Answer:

Yes, at a time t such that (√2)/2 ≤ t ≤ 2.

Explanation:

To answer the question

Therefore, where the domain of the function is the set of all real numbers x for which f(x) is a real number we have

For Chloe's velocity

$C(t) = t\times e^{4-t^2} \ for \ 0\leq t\leq 2$

Finding the boundaries of the function gives;

$0\times e^{4-0^2} = 0$ and $2\times e^{4-2^2} = 2$

At t = 1, we have $1\times e^{4-1^2} = e^{3} = 20.086$

We find the maximum point as follows;

$\frac{\mathrm{d} \left (t\times e^{4-t^2} \right )}{\mathrm{d} x}=0$

From which we have;

$\frac{\mathrm{} e^{4-t^2} - t\times e^{4-t^2} \times2\times t }{(e^{4-t^2} )^2}=0$

$e^{4-t^2} - t\times e^{4-t^2} \times2\times t }=0$

$e^{4-t^2}(1 - t\times2\times t })=0\\e^{4-t^2}(1 - 2\times t^2 })=0\\$

$e^{4-t^2}=0$ or $(1 - 2\times t^2 })=0$

∴ 1 = 2·t² and from which t = (√2)/2

Hence the function C(x) is decreasing from t = (√2)/2 to t = 2

For Brandon

For 0 ≤ t ≤ 1, 1 ≤ B(t) ≤8 and for 1 < t ≤ 2, 8 < B(t) ≤ 1.5

1 ≤ f(x) ≤ 1.5

Given that the function B(t) is differentiable, therefore, continuous, there exists a point at which the function C(t) and B(t) intersects given that;

For 0 ≤ t ≤ (√2)/2, 0 ≤ C(t) ≤ 23.416 for (√2)/2 < t ≤ 2, 23.416 > C(t) ≥ 2

and for 0 ≤ t ≤ 0 1 ≤ B(t) ≤ 8 and for 1 < t ≤ 2, 8 > B(t) ≥ 1.5

Therefore, the curves intersect at in between (√2)/2 ≤ t ≤ 2.

What is a parallel universe, and could there potentially be ones that contain doppelgängers of everyone on Earth?

Inessa [10]

Answer:

A parallel universe is a universe that sits alongside many other parallel universes in what is known as a universe. It is a theory, which means there isn’t much evidence to back it up.

In this theory, there is an infinite number of universes, so yes, there is one with doppelgangers of everyone on earth. There is one where an asteroid hits the earth every year and wipes out any possible life in the process. There is another where the earth doesn’t exist.

Using specific details and examples from the article, explain both site and

Diano4ka-milaya [45]

The site and situation factors that are considered by industries in their decision to move their manufacturers south of the border into Mexico is given below:

Situation factors :

This includes costs linked with the set up transportation networks that is only accessible from a particular place.

Skilled labor and rapid delivery to market.

Site factors

costs linked with Land, labor, and capital.

<h3>Why are situation factors vital?</h3>

They are known to be vital because factories finds ways to identify a location that best suit the pint where their production cost is said to be minimized.

Note that the critical industrial location costs are part of some situation factors that firms do consider along with site factors when setting up an industry.
