Answer:

N (-1, -2), L (-3, 2), M (0, 4)

Step-by-step explanation:

When a point is reflected over the x-axis, <em>the y value simply becomes negative when it was positive, and vise-versa</em>.

The y-values of N', L', and M' are <em>1, 3, and 0</em>, respectively.

If they become negative, they are now <em>-1, -3, and 0</em>.

The x- values stay the same, which are -2, 2, and 4.

Their original coordinates are (-1, -2), (-3, 2), and (0, 4)

Which pair of angles are vertical angles?

Vlad1618 [11]

ANSWER

$< \: WRS \: \:and \: < \: \: VRT$

EXPLANATION

Vertical angles face each other directly opposite just like the angles formed on the opposite sides of the letter X.

Vertical angles, also called vertically opposite angles are equal.

From the above diagram,
$< \: WRS= < \: VRT$

because they are vertically opposite to each other.

The correct answer is B.

Find the partial derivatives of the function w=4r2+6s2+

lyudmila [28]

I'm taking the liberty of editing your function as follows: <span>w=4r^2+6s^2, where I use " ^ " to indicate exponentiation.

The partial of w with respect to r is 8r. That with respect to s is 12s.</span>

<h2>Alex accidentally forgot to stock up on toilet paper before the stay-at-home order. Now he has to buy toilet paper on the black market. Though the price of toilet paper on the black market has mostly stabilized, it still varies from day to day. The daily price of a generic brand 12-pack, X, and the daily price of a generic brand 6-pack, Y, (in rubles) jointly follow a bivariate normal distribution with: </h2><h2>μx = 2,470, σx = 30, μy = 1,250, σ = 25, p = 0.60. </h2><h2>(a) What is the probability that 2 (two) 6-packs cost more than 1 (one) 12-pack? (b) To ensure that he will not be without toilet paper ever again, Alex buys 7 (seven) 12-packs and 18 (eighteen) 6-packs. What is the probability that he paid more than 40,000 rubles? </h2><h2>(c) Suppose that today's price of a 12-pack is 2,460 rubles. What is the probability that a 6-pack costs less than 1,234 rubles today? [1 US dollar is approximately 75 rubles ]</h2>
