Anything added or subtracted from x INSIDE a perentesis will shift our graph to the left (if subtracted) or to the right (if added).
we need to find Ks that shift our graph to the right (we need Ks that are ultimately ADDED to x).
so just plug in the options and see which ones work. hint: they are -130, -458, -214
(keep in mind that there is a negetive before k in f(x) so any negetive will be positive and any positive will be negetive

$\bf \textit{volume of a cylinder}=v=\pi r^2 h\qquad 
\begin{cases}
r=radius\\
h=height\\
---------\\
r=6\\
v=864\pi^3
\end{cases}
\\\\\\
864\pi^3=\pi\cdot 6^2\cdot h\impliedby \textit{solve for "h"}$

I can't see the price for shoe rentals but the expression should be
total cost in dollars (y)=(number of games (3) X the price of a game ($4)) + price of shoes. Plug in your values and you should get y=$12+shoes.

Please may someone help with c

Step-by-step explanation:

Distance between two villages = d

$(a) \: \frac{4}{5} \: of \: d = \frac{4}{5} d \\ \\ (b) \: \frac{3}{4} \: of \: d = \frac{3}{4} d \\ \\ (c) \: \frac{4}{5} d - \frac{3}{4} d = 1.5 \\ \\ \therefore \: \bigg(\frac{4}{5} - \frac{3}{4} \bigg) d = 1.5 \\ \\ \therefore \: \bigg(\frac{4 \times 4 - 3 \times 5}{5 \times 4} \bigg) d = 1.5 \\ \\ \therefore \: \bigg(\frac{16- 15}{20} \bigg) d = 1.5 \\ \\ \therefore \: \bigg(\frac{1}{20} \bigg) d = 1.5 \\ \\ \therefore \: d = 1.5 \times 20 \\ \\ \: \: \: \: \: \huge \orange{ \boxed{{ \therefore \: d = 30}}}$

Examine the data below for a stalk of corn. Logarithmic regression Use logarithmic regression to find an equation of the form y

masya89 [10]

The value of a and b for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.

<h3>What is logarithmic regression?</h3>

Logarithmic regression is a type of regression which is used to model the statement in which the growth or decay initially at rapid rate, and then slow down with respect to time.

The data of the table for the day and height of the stalk of corn is listed below.

Day (x) 9 12 22 40

Height (y) in 5 17 45 60

Mean of x values,

$m_x=\dfrac{9+12+22+40}{4}\\m_x=17.5581$

Mean of y values,

$m_y=\dfrac{5+17+45+60}{4}\\m_y=31.75$

For the above table, the value of correlation coefficient is 0.99133. For these values, the logarithmic regression can be given as,

$y = -76.2038+37.6735\ln(x)$

Compare it with the following logarithmic regression equation, we get

$y = a+b\ln(x)$

$a=-76.2038\\b=37.6735$

Hence, the value of a and b for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.
