A child builds two wooden train sets. The path of one of the trains can be represented by the function y = 2cos2x, where y repre

Svet_ta [14]

Using a trigonometric equation, it is found that it will take 2.28 minutes until the two trains are first equidistant from the child.

<h3>What is the distance of each train to the child?</h3>

The distance of the first train is:

$y_1 = 2\cos^{2}x$

The distance of the second train is:

$y_2 = 3 + \cos{x}$

<h3>When are the trains equidistant to the child?</h3>

When $y_1 = y_2$ , hence:

$2\cos^{2}x = 3 + \cos{x}$

The following substitution is made:

$z = \cos{x}$

Hence:

$2z^2 = 3 + z$

$2z^2 - z - 3 = 0$

Which is a quadratic equation with coefficients $a = 2, b = -1, c = -3$ , hence:

$\Delta = b^2 - 4ac = (-1)^2 - 4(1)(-3) = 13$

$z_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{1 + \sqrt{13}}{4} = 1.5$

$z_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{1 - \sqrt{13}}{4} = -0.65$

Then, applying the trigonometric equation, considering that $-1 \leq z \leq 1$ due to the range of the cosine function:

$z_2 = \cos{x_2}$

$x_2 = \arccos{z_2} = \arccos{-0.65} = 2.28$

It will take 2.28 minutes until the two trains are first equidistant from the child.

nolan completely fills a glass with water and then pours the water into a bowl. he does this until the bowl is completely filled

Firdavs [7]

Answer:

$\bold{3\dfrac{1}{2 }}$ full glasses of water the bowl holds.

Step-by-step explanation:

Full glass of water holds $1\frac{1}{3}$ cups of water.

Full bowl of water holds $4\frac{2}{3}$ cups of water.

To find:

How many full glasses of water does the bowl hold ?

Solution:

Let us convert the unit of cups of water to glass of water.

Given that

$1\frac{1}{3}$ or $\frac{4}{3}$ cups of water is equivalent to 1 full glass of water

Now, let us use unitary method to find the answer.

$\frac{4}{3}$ cups of water is equivalent to 1 full glass of water

1 cups of water is equivalent to $\frac{3}{4}$ full glass of water

$4\frac{2}{3}$ or $\frac{14}{4}$ cups of water is equivalent to $\frac{3}{4}\times \frac{14}3 = \frac{14}{4}$ full glass of water

$\dfrac{14}{4} = \dfrac{7}{2} = \bold{3\dfrac{1}{2}}$ full glass of water is the quantity the bowl holds.
