A science experiment begins with a bacterial population of 12. After 1 hour, the population is 18. After 2 hours, the population

is 27. Which best describes the relationship between the time, in hours, and the population of the bacteria? What is the y-intercept of the function? What is the rate of change of the function?

So it starts with 12 in the bacterial population. After 1 hour, 6 are added. After another hour passed, 9 are added. 12/1, 18/6, 27/9.

Answer:

We can show that ∆ABC is congruent to ∆A′B′C′ by a translation of (x-2, y) unit(s) and a across the x-axis.

Step-by-step explanation:

The triangle ABC is shown in the image attached. The coordinates of the triangle are A(8, 8), B(10, 4), C(2, 6), while the triangle A'B'C' is at A'(6, -8), B'(8, -4), C'(0, -6).

A transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, dilation and rotation.

If a point O(x, y) is translated a units on the x axis and b units on the y axis, the new coordinate is O'(x+a, y+b).

If a point O(x, y) is reflected across the x axis, the new coordinate is O'(x, -y)

Hence if triangle ABC is translated -2 units on the x axis (2 units left), the new coordinates are A*(6, 8), B*(8, 4), C*(0, 6). If a reflection across the x axis is then done, the new coordinates are A'(6, -8), B'(8, -4), C'(0, -6).

Please, i need help :(

Answer:

First of all, find x from the Pythagorean theorem a^2+b^2=c^2, which c is the hypotenuse. 

7^2+24^2=c^2

49+576=c^2

c^2=625

c=25 or x=25

Next, we have to figure out the value of y and z. So, you need to use inverse trigonometric functions.

arctan(\frac{7}{24})=y=16.3 degrees. arctan(\frac{24}{7})=z=73.7 degrees.

All in all, the values are

x=25

y=16.3

z=73.7

Hope this helps and have a nice day!
