Graph the function shown g(x)=-|x-4|
il63 [147K]

Using translation concepts, the graph of g(x) = -|x - 4| is shown at the end of the answer.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The graph of g(x) = -|x - 4| is the graph of f(x) = |x| with these following changes:

  • Reflection over the x-axis.
  • Shift right of 4 units.

At the end of the answer, the graph shows functions f(x) in red and g(x) in blue.

Tara and Veronica are in charge of making a banner for the volleyball game this Saturday.How much poster paper will they need fo
lesantik [10]
The answer is 21 7/8.

The quantity of the paper needed is the area of parallelogram with a height 3 1/2 and base 6 1/4. The area of a parallelogram (A) is the product of its height (h) and base (b):
A = h * b

We have:
h = 3 \frac{1}{2} = 3 + \frac{1}{2} = \frac{3}{1} +\frac{1}{2}= \frac{3*2}{1*2}+\frac{1}{2}=\frac{6}{2}+\frac{1}{2}=\frac{7}{2} \\ \\ b = 6 \frac{1}{4} = 6 + \frac{1}{4} = \frac{6}{1} +\frac{1}{4}= \frac{6*4}{1*4}+\frac{1}{4}=\frac{24}{4}+\frac{1}{4}=\frac{25}{4}


Thus, the area of paralleogram is:
A = b * h =  \frac{7}{2} *  \frac{25}{4} =  \frac{7*25}{2*4} =  \frac{175}{8} =  \frac{168+7}{8} = \frac{168}{8} + \frac{7}{8} = 21+ \frac{7}{8}=21\frac{7}{8}

Factorise<br><br>a² - 144<br>Please factorise this​
charle [14.2K]

Answer:

  • \bf\pink{(a-12)\times (a+12)}

Step-by-step explanation:

<h2><u>Given Expression</u> :-</h2>

  • \bf\blue{a^{2} - 144}

<h2><u>Steps to factorise</u> :-</h2>

\longrightarrow\:\:\bf\red{a^{2} - 144}

  • Write the number in the exponential form with an exponent of 2

\longrightarrow\:\:\bf\orange{a^{2}-12^{2}}

  • Using a²-b² = (a-b)(a+b), factor the expression.

\longrightarrow\:\:\bf\purple{(a-12)\times (a+12)}

(<u>Refer the attachment for graph representation</u>)

<h2><u>Graph Details</u> :-</h2>

\bigstar\:\:\bf{y=a^{2}-144}

  • \rm{ Roots \:\:(-12,\:0)\:(12,\:0)}

  • \rm{Domain \:\:a \in {\mathbb{R}}}

  • \rm{Range \:\:y\in \bigg( -144,\:+\infty \bigg) }

  • \rm{Minimum \:\: (0,\:-144)}

  • \rm{Vertical\: Intercept\:\:(0,\:-144)}

Len [333]
11.81 dollars the way i got this is 5.25 multiplied by 2 is 10.30 and 15 divided by 60 is 4 so 1/4 times 5.25 is 1.31 which was rounded that is why it is 11.81 dollars.
