Which equation defines the graph of y=x^2 after it is shifted vertically 3 units down and horizontally 5 units left? A) y=(x-5)^

jeka94

The answers is B because you set x+5=0 and x=-5 so that means that the graph needs to be shifted 5 units to the left because 5 is negative and to move 3 units down you just put a -3 at the end of the equation like this y=(x+5)-3

The new iPhone 3.14 is being sold at the UT Math Department. The original price is $1200 (day 0), but they are going to decrease

Marat540 [252]

$\bf \qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{accumulated amount}\dotfill&50.14\\ P=\textit{initial amount}\dotfill &1200\\ r=rate\to r\%\to \frac{r}{100}\dotfill\\ t=\textit{elapsed time}\dotfill &16\\ \end{cases}$

$\bf 50.14=1200(1-r)^{16}\implies \cfrac{50.14}{1200}=(1-r)^{16}\implies \sqrt[16]{\cfrac{50.14}{1200}}=1-r \\\\\\ r=1-\sqrt[16]{\cfrac{50.14}{1200}}\implies r\approx 0.18\implies \stackrel{\textit{converting to percent}}{r\approx 0.18\cdot 100}\implies r\approx \stackrel{\%}{18}\quad \leftarrow x$

1 - 4 please help !!!!

dusya [7]

We can use the slope formula for each of these.

$\frac{y.2 - y.1}{x.2 - x.1} = m$

1. 5 - 1 / 4 - 2

4 / 2

2

The slope is 2, and it is rising because it is positive.

2. -5 - 0 / 3 - (-1)

-5 / 4

The slope is -5/4, and it is falling because it is negative.

3. 1 - 1 / -3 - 2

0 / -5

0

The slope is 0, and it is a horizontal line. The value of y is not changing per value of x.

4. -5 - 2 / -1 - (-1)

-7 / 0

Undefined

The slope is undefined because it fails the vertical line test.

Translate the following into an expression: 40% off the price of r dollars 40(0)

Darina [25.2K]

Answer:

0.4r

Step-by-step explanation:

40% of the price of r dollars

To translate into an expression, we outline te keywords

Percentage of price = 40%

The price in question = $r

Hence, the expression will calculate, 40% of the price

Hence, we'll have :

40% of price

(40 / 100) * r

0.4 * r

= 0.4r
