How many significant digits are in 80,000

Answers

Answer 1
Answer: 2 because the equation can be reduced to: 8.0 x 10^4.
Answer 2
Answer: Actually it's 5 because there is no decimal space and if you only include 8 then that means the number is actually 8.

  • Distance Formula: d = √((x_2-x_1)^2+(y_2-y_1)^2)

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point A (-4, 2)

Point B (8, 6)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

  1. Substitute [DF]:                    d = √((8+4)^2+(6-2)^2)
  2. Add/Subtract:                       d = √((12)^2+(4)^2)
  3. Exponents:                           d = √(144+16)
  4. Add:                                      d = √(160)
  5. Simplify:                                d = 4√(10)
  6. Evaluate:                              d = 12.6491
  7. Round:                                 d \approx 12.6

Can you have 2 vertical asymptotes?

Answers

YES. you can have 2 vertical asymptotes.

So I'll set the denominator equal to zero and solve. Since I can't have a zero in the denominator, then I can't have x = –4 or x = 2 in the domain. This tells me that the vertical asymptotes (which tell me where the graph can not go) will be at the values x = –4 or x = 2. hope this helped.:)
