Answer:

(d) No, the figures are different sizes

Step-by-step explanation:

Congruent figures have corresponding sides the same length. A'''B''' is not the same length as AB, so the figures cannot be congruent.

Congruence is sometimes shown by identifying rigid transformations that map one figure onto another. Rigid transformations preserve size. The sizes these figures are different, so rigid transformations cannot be used to map one figure to the other. The appropriate statement of this is choice D.

1.4x+3.5y please i need help ;-;

Step2247 [10]

If it’s only 1.4x + 3.5y then that’s the answer because you can’t do anything with them. Since one has an x variable and the other has a y variable you can’t combine them together.

The population of a town increases by 4 % every year . In the last year the population of the town was 110000.

TEA [102]

Answer:

114,400 and 118,976.

Step-by-step explanation:

Let's represent this using a function. Let's let:

$P(y)$ represent the total population, and $y$ represent the total number of years since last year.

We know that the population grows by 4% every year or 0.04 every year. This is exponential growth. We can write this as:

$P(y)=110000(1.04)^y$

Note that the coefficient is 110000 because that is the year we are starting with. Also, note that it is 1.04 because we are essentially adding .04 to the original population.

Anyways, to find the present population, set y equal to 1 (because 1 year after last year is the present year)

$P(1)=110000(1.04)^1=114400$

The present population is 114,400 people.

For next year, set y equal to 2 (2 years after last year is next year)>

$P(2)=110000(1.04)^2=118976$

The population next year will be 118,976 people.
