Answer:

f(5) = 11 inches

Step-by-step explanation:

<em>The function we could use to solve this is </em> $f(x) = 2\frac{1}{5} x$ !

Since x is our input value and is used to represent the time/days passed, we can substitute the x value in the equation for 5!

$f(5) = 2\frac{1}{5}(5)\\2\frac{1}{5} *5= 11!$

So the height in 5 days should be 11 inches!

Which of the following explains why f(x) = log4^x

AVprozaik [17]

Answer:

There is no power of 4 that is equal to 0.

Step-by-step explanation:

$f(x) = log \: {4}^{x} \\ \\ plug \: x = 0 \\ \\ f(0) = log \: {4}^{0} \\ \\ f(0) = log \: 1 \: ( \because \: {n}^{0} = 1) \\ \\ f(0) = 0 \: ( \because \: log \: 1 = 0)$

Hence, f(x) = log4^x

does not have a y-intercept.

What is the answer to this math question?

oksano4ka [1.4K]

Answer:

The answer is option 3.

Step-by-step explanation:

First we have to find the area of both rectangle and triangle :

Rectangle,

$area = base \times height$

Let base = 9,

Let height = 3,

$area = 9 \times 3 \\ area = 27 \: {m}^{2}$

Triangle,

$area = \frac{1}{2} \times base \times height$

Let base = 3,

Let height = 3,

$area = \frac{1}{2} \times 3 \times 3 \\ area = \frac{1}{2} \times 9 \\ area = \frac{9}{2} \\ area = 4.5 \: {m}^{2}$

Lastly, in order to find the shaded region you have to substract the area of triangle from the area of rectangle :

$area = 27 - 4.5 \\ area = 22.5 \: {m}^{2}$
