A hat is marked down 45% and its new price is $69. What was the original price rounded to the nearest cent?

Alex Ar [27]

Answer:

$106.95

Step-by-step explanation:

45% = 0.45

1.00 - 0.45 = 0.55

$69 x 0.55 = 37.95

$69 + 37.95 = $106.95

A system of equations is shown below. Which of the following statements describes the graph of this system of equations in the (

katovenus [111]

Answer:

C

Step-by-step explanation:

3y - 5x = 15 ... A

y = 5/3 * X +15 .... slope 3/5 , y intercept 15

6y - 10x =30

(6y - 10x) /2 = 30 / 2

3y - 5x = 15 ... B

y = 5/3 * x + 15 ..... slope 3/5 , y intercept 15

∴ Answer is C

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line.

Elza [17]

Answer:

$\frac{\pi}{18}(e^{10} - e^8) \approx 3324$

Step-by-step explanation:

We begin by solving for x in term of y

$y = ln(3x)$

$e^y = 3x$

$x = \frac{e^y}{3}$

We can use the disk method to calculate the volume of rotation around the y axis

$V = \int\limits^5_4 {\pi r^2} \, dy$

Where $r = x = \frac{e^y}{3}$

$V = \int\limits^5_4 {\pi \left(\frac{e^y}{3}\right)^2} \, dy\\V = \frac{\pi}{9}\int\limits^5_4 {e^{2y}} \, dy\\\\V = \frac{\pi}{9}\left[\frac{e^{2y}}{2}\right]^5_4\\V = \frac{\pi}{9}(e^{10}/2 - e^8/2) = \frac{\pi}{18}(e^{10} - e^8)\\ V = \frac{\pi}{18}19045.5 \approx 3324$
