Step-by-step explanation:

The 2 lines are parallel to each other which means that angle #5 and 93° are alternate interior angles so by definition, they are equal. Hence angle 5 = 93°

Which function is the inverse of f(x) = -5x-4?

tankabanditka [31]

Step-by-step explanation:

$f(x) = - 5x - 4$

$\:$

<u>Inverse</u>

$y = - 5x - 4$

$x = - 5y - 4$

$x + 4 = - 5y$

$y = - \frac{(x + 4)}{5}$

${f}^{ - 1} (x) = - \frac{(x + 4)}{5}$

Question 14(Multiple Choice Worth 5 points)

ddd [48]

Answer:

Find all polar coordinates of point P where P = (5 , -pi+%2F6 ).

There are two sets of possibilities.

(1) Same (positive) magnitude and an angle that is the same as the given angle, or differs from the given angle by an even multiple of pi:

P = (5, -pi%2F6%2B2n%2Api )

(2) Opposite (negative) magnitude and an angle that differs from the given angle by an odd multiple of pi:

(-5, -pi%2F6%2B%282n%2B1%29pi)

answer is: (5,-pi%2F6+%2B+2n%2Api) or (-5, -pi%2F6%2B%282n%2B1%29pi)

What is the average rate of change of the amount of the element over the 10-minute experiment? *

Dima020 [189]

Answer:

$-2.7 g/min$

Step-by-step explanation:

Given: a graph

To find: the average rate of change of the amount of the element over the 10-minute experiment

Solution:

A rate of change of one quantity with respect to another quantity is known as rate of change. If y is the dependent variable and x is the independent variable then average rate of change = change in y /change in x.

From the graph,

change in x (time) = $10-0=10$ minutes

change in y ( amount of the element) = $3.22-30=-26.78$ g

So, average rate of change = $\frac{-26.78}{10} =-2.7 g/min$
