Answer:

Step-by-step explanation:

3.4 rounded to the nearest whole number would be 3 because the tenths place is under .5 therefore it would be rounded to 3 instead of 4.

If it was 3.5 or higher it would be rounded to 4 because it is .5 or higher.

hope this helps!!

(solve for x ) −28−1/5n=3/5n

almond37 [142]

Answer:

$- 28 - \frac{1}{5} n = \frac{3}{5} n \\ - 28 = \frac{1}{5} n + \frac{3}{5} n \\ - 28 = \frac{4}{5} n \\ n = \frac{( - 28) \times 5}{4} \\ n = ( - 7) \times 5 \\ \boxed{ n = - 35}$

<u>n=-35</u> is the right answer.

Find the equation for the set of points whose distance from the y-axis equals the distance from the xz-plane.

julia-pushkina [17]

Answer:

$x_1^2 + z_1^2 = y_1^2$

Step-by-step explanation:

Let $p(x_1, y_1, z_1)$ be the point.

Any point on y-axis is (0, y, 0)

So, distance is

= $\sqrt{x_1^2+0 + z_1^2}$

= $\sqrt{x_1^2 + z_1^2}$ ......(1)

Now any point on x-z plane is $( x_1, 0, z_1 )$

Distance from p to this point is

= $\sqrt{0+y_1^2 + 0}$

= $\sqrt{y_1^2}$ .........(2)

Equating (1) and (2), we get

$\sqrt{x_1^2 + z_1^2} = \sqrt{y_1^2}$

$x_1^2 + z_1^2 = y_1^2$

This is the required equation.
