Can someone help me round 621x29

1 answer:

Your rounded number is 18010

The reason for this is because when you multiply 621X29, you get 18009. When you round numbers, you want to see how the numbers are. If a number is 4 or below, you will make that number a zero or not count it, whereas numbers above 5 will go up. I hope this helps and if you have any questions, let me know

Describe the region enclosed by the circle x^2 +y^2 = 11x in polar coordinates.

vivado [14]

Answer:

the region of the circle in polar coordinate can be expressed as:

$\mathbf{- \dfrac{\pi}{2} \leq \theta \leq \dfrac{\pi}{2} , 0 \leq r \leq 11 cos \theta}$

Step-by-step explanation:

Given that:

$x^2 +y^2 = 11x$

This implies that :

$(x-5.5)^2 + y^2 = 5.5^2$

center (5.5, 0) and radius = 5.5

The relation between the cartesian coordinates (x,y) and the polar coordinates (r, θ) is as follows:

x = rcosθ

y = rsinθ

Thus, $x^2 + y^2 = r^2$

$x^2 + y^2 = 11x$

$(rcos \theta)^2 + (r sin \theta)^2 = 11(rcos \theta)$

$r^2 = 11r cos \theta$

Thus, the angle θ runs between $- \dfrac{\pi}{2}$ to $\dfrac{\pi}{2}$

Therefore, the region of the circle in polar coordinate can be expressed as:

$\mathbf{- \dfrac{\pi}{2} \leq \theta \leq \dfrac{\pi}{2} , 0 \leq r \leq 11 cos \theta}$

you buy 70 of your favorite songs from a web site that charges 0.97 for each song. what is the cost of 70 songs?

Lelechka [254]

Answer:

$67.90

Step-by-step explanation:

One song = 0.97

You buy 70 songs

0.97 * 70 = 67.9

Since it deals with money you have two decimal places and add the $

So it will come to $67.90
