What is the average value of latex: y=\tan\left(\frac{x^2}{9}\right) y = tan ⁡ ( x 2 9 ) on the closed interval [1.25, 2]?

german

For this case we have the following function:
$f(x) = tan(\frac{x^2}{9})$
The average rate of change is given by:
$AVR = \frac{f(x2) - f(x1)}{x2- x1}$
Evaluating the function for the given interval we have:
For x = 1.25:
$f(1.25) = tan(\frac{1.25^2}{9})$
$f(1.25) = 0.18$
For x = 2:
$f(2) = tan(\frac{2^2}{9})$
$f(2) = 0.48$
Then, replacing values we have:
$AVR = \frac{0.48 - 0.18}{2 - 1.25}$
$AVR = 0.4$
Answer:
the average value of on the closed interval [1.25, 2] is:
$AVR = 0.4$

Express the ratio in the simplest form. 20 gallons to 0.75 gallons

expeople1 [14]

ANSWER

The ratio in the simplified form is

80:3

EXPLANATION

We want to express 20 gallons to 0.75 gallons as a ratio in its simplest form.

We obtain the ratio as follows:

$20:0.75$

This is the same as

$20: \frac{3}{4}$

We multiply each term in the ratio by 4 to obtain;

$20 \times 4:0.75 \times 4$

This gives us,

$80:3$
