Lillian had 2 two-liter bottles of soda, which she distributed equally between 10 glasses.

alexgriva [62]

<u><em>Answers:</em></u>

a. $\frac{2}{5}$ liters/glass

b. 0.4 liters/glass

c. 400 ml/glass

<u><em>Explanation:</em></u>

<u>Part a:</u>

We are given that two bottles each holding 2 liters of soda

This means that the total amount of soda = 2 * 2 = 4 liters

To get the amount of soda in each glass, we will simply divide the amount of soda by the number of glasses (given the number of glasses is 10)

<u>Therefore:</u>

Amount of soda in each glass = $\frac{4}{10} = \frac{2}{5}$ liters/glass

<u>Part b:</u>

We are now asked to express the amount in fraction. The simplest way to do this is to make the denominator a multiple of 10. The number of zeroes in the denominator will be equal to the number of digits after the decimal point

<u>Therefore:</u>

$\frac{2}{5}=\frac{4}{10}=0.4$ liters/glass

<u>Part c:</u>

Now, we know that 1 liter is equivalent to 1000 ml

<u>Therefore:</u>

0.4 liters = 0.4 × 1000 = 400 ml/glass

Hope this helps :)

Determine o período e o conjunto imagem, construindo o gráfico de um período completo para cada função dada.a) por f(x) = 1+ 4 s

nataly862011 [7]

Answer:

The given functions are

$f(x)=1+4sinx$

$f(x)=2sin(x-3)$

The sine function has a standard period of $2 \pi$ by definition. However, this might change if we use a factor as coefficient of the x-varible, but in this case we don't have that.

Therefore, the period of both trigonometric functions is $2 \pi$ .

Now, the images of each function is the y-variable set values that defines each function.

So, the function $f(x)=1+4sinx$ has an image defined by the set $[-3,5]$ . It's impotant to notice that the range of a standard function is [-1,1], however, in this case, the function was shifted 1 unit up and it was streched by a factor of 4, that's why the standard image changes to $[-3,5]$ .

About the second function $f(x)=2sin(x-3)$ , the image set is $[-2,2]$ , because the function was streched by a factor of 2.

Additionally, the image attached shows the graph of the given functions.

Please help with this AP Calculus question !

melomori [17]

Answer:

C. $\displaystyle \frac{cos(x)}{x} - ln(x)sin(x)$

General Formulas and Concepts:

<u>Calculus</u>

Differentiation

Derivatives
Derivative Notation

Derivative Rule [Product Rule]: $\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Trig Derivatives

Logarithmic Derivatives

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

$\displaystyle f(x) = ln(x)cos(x)$

<u>Step 2: Differentiate</u>

Derivative Rule [Product Rule]: $\displaystyle f'(x) = \frac{d}{dx}[ln(x)]cos(x) + ln(x)\frac{d}{dx}[cos(x)]$
Logarithmic Derivative: $\displaystyle f'(x) = \frac{1}{x}cos(x) + ln(x)\frac{d}{dx}[cos(x)]$
Trig Derivative: $\displaystyle f'(x) = \frac{1}{x}cos(x) + ln(x)[-sin(x)]$
Simplify: $\displaystyle f'(x) = \frac{cos(x)}{x} - ln(x)sin(x)$
