Graph the result of the following transformation on f(x)

pshichka [43]

The graph would be the normal parent function of f(x) but all points would be 6 units up.

There's an upward vertical shift of 6. To graph this, you need to graph the function f(x) and then add 6 units to all the y values.

3. A rock club's profit from booking local bands depends on the ticket price, Using past receipts, the owners find that the prof

jarptica [38.1K]

$p=-10t^2\text{ + 500t + 60}$

Part A

To find the ticket price when the price is $16

Let us substitute the value of t = 16

p = -10 x (16 x16) + 500 x 16 + 60

p = -2560 + 8000 + 60

p =$ 5500

Part B

To get the maximum profit, we will have to differentiate P with respect to t

$\begin{gathered} p=-10t^2\text{ + 500t + 60} \\ \frac{dp\text{ }}{dx}=\text{ -20t + 500} \end{gathered}$

The maximum profit will be obtained when the derivative is zero

-20t + 500 = 0

20t = 500

t = 500/20

t = 25

This means that the ticket price has to be $25 so as to obtain the maximum price

Part C

The maximum profit will be obtained by substituting t = 25 into the original equation

$\begin{gathered} p=-10t^2\text{ + 500t + 60} \\ p\text{ = -10 x 25 x 25 + 500 x 25 + 60} \\ p\text{ =}6310 \end{gathered}$

An account earns simple interest. Find the interest earned. $1200 at 2.8% for 30 months

sasho [114]

let's bear in mind that a year has 12 months, so 30 months is really 30/12 years.

$\bf ~~~~~~ \textit{Simple Interest Earned}
\\\\
I = Prt\qquad
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\dotfill & \$1200\\
r=rate\to 2.8\%\to \frac{2.8}{100}\dotfill &0.028\\
t=years\to \frac{30}{12}\dotfill &\frac{5}{2}
\end{cases}
\\\\\\
I=(1200)(0.028)\left( \frac{5}{2} \right)\implies I=84$

Becky is tossing a six-sided nbee cube labeled 1,2,3,4,5, and 6.What is the probability of tossing 6 two times in a row?

GenaCL600 [577]

Odds of rolling a 6 is 1/6. the odds of rolling another 6 is still 1/6. the number on the first toss has no effect on the second (this is called independent events) so you multiply the probabilities together

1/6 * 1/6 = 1/36
