Rotation in mathematics involves movement of a figure along a given point and a given angle. It is described by giving a the center of rotation and the angle of rotation, the angle indicates the direction of rotation whether clockwise or anticlockwise, such that if the angle is positive then the rotation is to the anticlockwise direction and if the angle is negative then the direction of rotation is clockwise. In our case the center of rotation is origin (0,0) and the angle of rotation is +180 degrees thus the direction of rotation is anticlockwise. Therefore if an object DEFG is rotated to an image D'E'F'G' , assuming point G was in the first quadrant then its image G' will fall on the third quadrant of the Cartesian plane.

For every $5 tent saved, his his dad will contribute $2 to his saving account. How much will Trent have to put into the account

KonstantinChe [14]

Answer:

$40

Step-by-step explanation:

Trent contributes 5/(5+2) = 5/7 of the amount in his account. For an amount of $56, he must contribute ...

(5/7)×$56 = $40

Trent will have to put $40 into the account before he can buy a $56 skateboard.

What is the recursive formula for this geometric sequence?<br> -2, -16, -128, -1024,

<h3>Answer: Choice A</h3>

The first line shown in choice A is $a_1 = -2$ which means "the first term is -2"

The next line in choice A means "the nth term ( $a_n$ ) is found by multiplying the prior term ( $a_{n-1}$ ) by 8". Put another way: multiply each term by 8 to get the next term.
