F(x) = 4 - 2x                   Domain = x = -4, 0, 5

f(x) = 4 - 2(-4) = 4 - (-8) = 12  

f(x) = 4 - 2(0) = 4 - 0 = 4

f(x) = 4 - 2(5) = 4 - 10 = -6

f(x) = 12, 4, -6

The range is C.

Find the value of the expression if x=-7
LUCKY_DIMON [66]

Answer: -16

Step-by-step explanation:

49 would be the result of -7 squared. Due to the fact it is negative, it would cancel out to be positive.

For the numerator, 49-1 is equivalent to 48.

48/x+4

-7+4 = -3

48/-3

= -16

A 2-column table has 4 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1. The second column is label
JulijaS [17]

The growth factor of the exponential function represented by the table is 5.

The correct option is c.

<h3>What is the growth factor of the exponential function?</h3>

The growth factor of the exponential function is the ratio of the two consecutive terms (y-values).

The growth factor of the exponential function is given by;

\rm Growth\ factor=\dfrac{y(x_2)}{y(x_1)}\\\\

As per given, we have a table;

x         y

-2     0.004

-1       0.02

0       0.1

1        0.5

The value  \rm x_2 is -2 and \rm x_1 is -1.

Therefore,

the growth factor of the exponential function represented by the table would be :

\rm Growth\ factor=\dfrac{y(x_2)}{y(x_1)}\\\ \rm Growth\ factor=\dfrac{y(-1)}{y(-2)}\\\\\rm Growth\ factor=\dfrac{0.02}{0.004}\\\\ \rm Growth\ factor=5

Hence, the growth factor of the exponential function represented by the table is 5.

Answer:

\theta = 40.59^\circ

Step-by-step explanation:

Given

The question is illustrated with the attached image

Required

Find \theta

To do this, we use sine formula

i.e.

\sin(\theta) = \frac{Opposite}{Hypotenuse}

So, we have:

\sin(\theta) = \frac{10.8}{16.6}

\sin(\theta) = 0.6506

Take arc sin

\theta = \sin^{-1}(0.6506)

\theta = 40.59^\circ

Using the given points, determine the slope. <br><br> (0, 32) and (100, 212)
Allushta [10]
Hi!

To find the slope of two given points, subtract the y values, and subtract the x values, or..

\frac{(y2 - y1)}{(x2 - x1)}

\frac{(212 - 32)}{(100 - 0)}

\frac{180}{100}

The answer is 9/5 or 1.8.

Hope this helps! :)
