Answer:

60

Step-by-step explanation:

You have the proper formula. You just need to swap some things around so we aren't solving for C. C is always the hypotenuse, the diagonal line opposite the right triangle. A and B can be either side unless specified.

1. The side we're solving for can either be called a or b. Let's call it A.

2. Now, switch around the theorem to solve for a: C^2-B^2=A^2\\

3. Plug in what we know: 8^2-2^2=a^2

4. It simplifies down to 60=a^2

5. The  "a^2 " means to square the a. We need to undo that to get a by itself. The opposite of squared is the square root

6. This leaves us to take the square root of both sides, which isolates a.

7. \sqrt{60} is the answer. It's asking for it in the square root so we don't need to simplify it.

A country's population in 1992 was 103 million. in 1997 in was 108 million. estimate the population in 2004 using the exponentia
BartSMP [9]
108=103e^(5k)

108/103=e^(5k)  take the natural log of both sides

ln(108/103)=5k

k=ln(108/103)/5

k≈0.00948

P=103e^(12*0.00948)

P≈115 million (to nearest million)

Answer:

5. y=-1 (the line of reflection)

6. 90 degrees CCW

7. move the figure 4 units right

8. Increase or multiply the figure by two...

Step-by-step explanation:

7.(add 4 to every x value) and 6 down (subtract 6 from every y-value)

8.J is 2 units up and one unit left of the origin so you'd multiply it by 2 so that it is 4 units up and 2 units left of the orgin. Repeat this for every point of the triangle
