I need help with this geometry question, matching the right ones to each other.

The transformations and their respective descriptions are:

A. (x, y) ⇒ (3x, y) implies horizontal stretch by a scale factor of 3

B. (x, y) ⇒ (x+3, y) implies translation 3 units right

C. (x, y) ⇒ (x, 3y) implies vertical stretch by a factor of 3

D. (x, y) ⇒ (x, y+3) implies implies translation 3 units up

E. (x, y) ⇒ (3x, 3y) implies dilation with a scale factor 3

<h3>What is Translation?</h3>

Translation is an algebraic transformation of a shape by moving the vertices some units along the x or y axis.

When a shape is translated it may move to a new position depending on the orientation of the translation.

Analysis:

For A, the x coordinate was transformed three times its initial value stretching it horizontally.

For B, the x coordinate moved 3 units further away from its initial value making the new value x+3 and y remaining the same.

For C, the y coordinated was transformed to a value three times what it was, making it to be stretched vertically, since the y-axis is a vertical axis.

For D, the y coordinate was moves 3 units away from its initial position making it to be translated up, since 3 is positive.

For E, both coordinates were stretched 3 units as much as their original value making the shape to dilate.

Use the distributive property to write an equivalent expression 4(5+19)=

wolverine [178]

$4 ( 5 + 19 ) \\ = 4(24) \\ = 4\times 24 \\ = \boxed{96 }$

Use distribute property & then multiply.
If you want an expression then, 96 = <u>2⁵ × 3</u><u>.</u>

A town has a population of 15000 and grows at 4.5% every year. To the

madreJ [45]

Answer:

In 8 years the population will reach 35900.

Step-by-step explanation:

Given : A town has a population of 15000 and grows at 4.5% every year.

To find : How long will it be until the population will reach 35900?

Solution :

The population growth can be identified by using $N=N_oe^{rt}$

Where,

N=35900 is future population

$N_o=15000$ is the initial population

t is the time taken

4.5%=0.045 is the rate of the growth

Rephrasing the formula to get the value of t,

$t=\frac{log(\frac{N}{N_0})}{r}$

Substituting the values,

$t = \frac{log(\frac{35900}{15000})}{0.045}$

$t = \frac{log(2.393)}{ 0.045}$

$t = \frac{0.3789}{ 0.045}$

$t =8.42$

$t\approx 8$

Therefore, In 8 years the population will reach 35900.
