Answer:

True False True

Step-by-step explanation:

1. A circle has 360 degrees in its interior. 360 - 130 (this is given) degrees = 230 degrees. This means it's TRUE

2. The area of the shaded sector is the degrees in the central angle that contains the sector, multiplied by the area of the circle. This means that the area is pi*r^2*angle. The radius is 10, and the angle is 230 degrees, so the answer is 100*230/360 pi = 23000/360 pi, which simplifies to 575/9 pi. This is FALSE.

3. The area of the shaded sector is area of the circle - area of the shaded sector. The area of the circle is pi r^2, which is 100 pi. 100 pi - 575/9 pi = 325pi/9, so this is TRUE

Which equation would you use to find how high the bird is flying

lisov135 [29]

Hi there! The fourth answer is correct.

In the picture we have to deal with facts:
1. The angle of 45°
2. The length of the opposite side
3. The length of the adjacent side.

Since we have to use the opposite and the adjacent side, we have to use the tangent of the angle. In a formula:
$\tan( \alpha ) = \frac{opposite}{adjecent}$

Filling in this formula, brings us to the following answer.
$\tan(45) = \frac{x}{1100}$

Find the coordinates of the image after a translation of the figure below using (x, y) (x + 3, y + 2).

vekshin1

You have not provided the coordinates of the original points, therefore, I cannot give exact answers.
However, I can help you with the concept.

We are given that the translation rule here is:
(x,y) ................> (x+3 , y+2)

This means that:
x coordinate of the translated point can be obtained by adding 3 to the x coordinate of the original point
y coordinate of the translated point can be obtained by adding 2 to the y coordinate of the original point

Examples:
point (2,3) after translation would become (2+3 , 3+2) which is (5,5)
point (-1,0) after translation would become (-1+3 , 0+2) which is (2,2)

Hope this helps :)
