If the mean of the four numbers 2x and 12 is 10, then x is

Lelu [443]

Answer:

4

Step-by-step explanation:

The mean of 2x and 12 is (2x+12)/2, so we get the equation:

(2x+12)/2 = 10 =>

x+6=10

x = 10-6 = 4

* Your question states four numbers, but you write only two... the answer could be wrong because of that.

Point A(2, 2) and point D(−4, −3) are located on the grid. Which measurement is closest to the distance between point A and poin

Virty [35]

Answer:

B

Step-by-step explanation:

The distance formula is $D=\sqrt{(y_2-y_1)^{2}+(x_2-x_1)^{2}}$

Where $(x_1,y_1)$ is the first coordinate (our case, point A(2,2)) & $(x_2,y_2)$ is the second coordinate (our case, point D(-4,-3))

<em>Plugging these in into the formula gives us:</em>

$D=\sqrt{(y_2-y_1)^{2}+(x_2-x_1)^{2}} \\D=\sqrt{(-3-2)^{2}+(-4-2))^{2}} \\D=\sqrt{(-5)^{2}+(-6)^{2}}\\ D=\sqrt{25+36} \\D=\sqrt{61} \\D=7.81$

Answer choice B is closest.

V125BC [204]

Answer:

f(2,2,4) = 8e^4 - 4

Step-by-step explanation:

Note that by integrating each entry of "f" with respect to the proper variable:

∇(yze^(x^2) + C) = {^(x^2), ze^(x^2), ye^(x^2) }

Hence, f(x,y,z) = yze^(x^2) + C

So, the Fundamental Theorem of Calculus for line integral yields

∫c f(x,y,z) · dr, where C is a path from (0,0,0) to (2,2,4)

= (yze^(x^2) {from (0,0,0) to (2,2,4)}

= 8e^4.

Now, let's solve for C, using f(0,0,0) = -4:

-4= 0 + C ⇒ C = -4.

So, f(x,y,z) = yze^(x^2) - 4

⇒ f(2,2,4) = 8e^4 - 4.
