Seo-Yun hosted a party. She had 50 party favors to give away, and she gave 3 party favors to each of her guests
fgiga [73]

Answer:

Arithmetic sequence

Step-by-step explanation:

-We notice that the difference between the number of favors already given out between any two consecutive number of party guests has an additive increment.

-This increment is called the Common Difference and has a value of 3.

-The number of tickets available is 50.

Hence, the number of tickets already given out can be calculated using the formula:

a_n=-dn+S_n\\\\n= n^{th} \ guest\\d=common \ difference\\S_n=Total \ tickets \ available\\\\\therefore a_n=-3n+50

Hence, this is an Arithmetic Sequence.

PLEASE HELP ME I DONT UNDERSTAND
Vlad1618 [11]

Answer:

Picture #1: x=16 ; y=10

Picture #2: x=21 ; y=15

Picture #3: x=18

Step-by-step explanation:

Picture #1:

(8x-14)* and (5x+34)* are Alternate Exterior Angle so they are congruent. And (8x-14)* and (5y+16)* are supplementary so they equal 180*.

Picture #2:

(6x+7)* and (3x-16)* are supplementary so they equal 180*. And (6x+7)* and (11y-32)* are Vertical Angles so they are congruent.

Picture #3:

(7x-6)* and (4x-7)* are supplementary so they equal 180*.

Find the radius of a circle, given that the center is at (3,-3) and the point (7,6) lies on the circle.
Alenkasestr [34]

Answer:

\large\boxed{radius=\sqrt{97}}

Step-by-step explanation:

The radius is the distance between the center and any point on the circle.

The formula of a distance between two points:

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

We have the center (3, -3) and other point on the circle (7, 6).

Substitute:

r=\sqrt{(6-(-3))^2+(7-3)^2}=\sqrt{9^2+4^2}=\sqrt{81+16}=\sqrt{97}
