In 2005, 8.1 x 10^10 text messages were sent in the United States. In 2010, the number of annual text messages had risen to 1,810,000,000,000. About how many times as great was the number of text messages in 2010 than 2005?

2.23456790123 x 10 ^ 2

Step-by-step explanation:

8.1 x 10^10 = 810,000,000,00( 10 Bounces from the decimal point) ( think of it as frog jums each jump is a single multiplication of 10 ^ 1)

1,810,000,000,000 = 1,81 x 10 ^12

1,81 x 10^ 12 - 8.1 x 10^ 10 =22.3456790123 = 2.23456790123 x 10 ^ 2

Hope i helped

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.
