Answer:

Step-by-step explanation:

The coordinates of A(- 2, 1 )

3 units right → + 3

2 units down → - 2

Add 3 units to the x-coordinate of A and subtract 2 from the y- coordinate

A' = (- 2 + 3, 1 - 2 ) = (1, - 1 ) → C

What is the distance from Cto D?

IRINA_888 [86]

Given:

The two points C(2,-1) and D(5,3) on a coordinate plane.

To find:

The distance from C to D.

Solution:

The distance between two points is defined by the distance formula.

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The two points are C(2,-1) and D(5,3). Using the distance formula, we get

$CD=\sqrt{(5-2)^2+(3-(-1))^2}$

$CD=\sqrt{(3)^2+(3+1)^2}$

$CD=\sqrt{(3)^2+4^2}$

On further simplification, we get

$CD=\sqrt{9+16}$

$CD=\sqrt{25}$

$CD=5$

The distance from point C to D is 5 units. Therefore, the correct option is A.

A spinner is divided into 10 equal sections numbered 1 through 10. If the arrow is spun once, what is the probability it will la

yarga [219]

The correct answer is A) 2/5

That is because the probability of it is equal to the number of numbers larger than 6 divided by 10, which is 4/10, or 2/5 when reduced.

Step-by-step explanation:

$\int _{2.2}^{+\infty \:}\frac{10.648}{x^2}dx = 10.648 \int _{2.2}^{\infty \:}\frac{dx}{x^2}$

$= - \frac{10.648}{x} | _{2.2}^{ \infty} = 4.84$
