The answer is D.

To find the mean you add all the numbers together and divide them by how many numbers there are.

22 + 37 + 49 + 15 + 72 = 195

195/5 = 39

Therefore, the answer is 39.

Answer: L' is (2,4) M' is (3,1) N' is (0,4)

Step-by-step explanation:

For each ordered pair, you add 2 to the x (the first number, which is horizontal on the graph) and 3 to the y (the second number, which is vertical).

L is (0,1) so you add 2 to the 0 and 3 to the 1 to get L' (2,4)

M is (1,-2), so you add 2 to the 1 and 3 to the -2 to get M' (3,1)

N is (-2,1), so you add 2 to the -2 and 3 to the 1 to get N' (0,4)

ANSWER ASAP! Geometry 10A

The coordinates of the vertices of each image are:

W' = (1 , 3) , X' = (4 , 2) , Y' = (1 , -3) , Z' = (-3 , 0) ⇒ C

Step-by-step explanation:

Let us revise the rotation about the origin

If point (x , y) rotated about the origin by angle 90° counterclockwise, then its image is (-y , x)
If point (x , y) rotated about the origin by angle 180° counterclockwise, then its image is (-x , -y)
If point (x , y) rotated about the origin by angle 270° counterclockwise, then its image is (y , -x)
If point (x , y) rotated about the origin by angle 90° clockwise, then its image is (y , -x)
If point (x , y) rotated about the origin by angle 180° clockwise, then its image is (-x , -y)
If point (x , y) rotated about the origin by angle 270° clockwise, then its image is (-y , x)
There is no difference between rotating 180° clockwise or counterclockwise around the origin

∵ The vertices of the figure are W (-3 , 1) , X (-2 , 4) , Y (3 , 1) , Z (0 , -3)

∵ The figure is rotated 90° clockwise (270° counterclockwise)

about the origin

- Change the sign of the x-coordinate of each point and switch the

two coordinates as the 3rd or 4th rule above

∴ W' = (1 , 3) , X' = (4 , 2) , Y' = (1 , -3) , Z' = (-3 , 0)

The coordinates of the vertices of each image are:

W' = (1 , 3) , X' = (4 , 2) , Y' = (1 , -3) , Z' = (-3 , 0)

Use l'Hôpital's Rule to find the following limit. ModifyingBelow lim With x right arrow 0StartFraction 3 sine (x )minus 3 x Ove

steposvetlana [31]

Answer:

$\lim_{x \to 0} \frac{3sinx-3x}{7x^3}=-\frac{1}{14}$

Step-by-step explanation:

The limit is:

$\lim_{x \to 0} \frac{3sinx-3x}{7x^3}=\frac{0}{0}$

so, you have an indeterminate result. By using the l'Hôpital's rule you have:

$\lim_{x \to 0} \frac{a(x)}{b(x)}= \lim_{x \to 0} \frac{a'(x)}{b'(x)}$

by replacing, and applying repeatedly you obtain:

$\lim_{x \to 0} \frac{3sinx-3x}{7x^3}= \lim_{x \to 0}\frac{3cosx-3}{21x^2}= \lim_{x \to 0}\frac{-3sinx}{42x}= \lim_{x \to 0}\frac{-3cosx}{42}\\\\ \lim_{x \to 0} \frac{3sinx-3x}{7x^3}=\frac{-3cos0}{42}=-\frac{1}{14}$

hence, the limit of the function is -1/14
