Can someone please help me 1. Write an equation to represent the relationship between the step number and the number of dots in the pattern.
2. Describe how each part of the equation relates to the pattern
3. Is the pattern in the previous question an example of a linear, exponential, or quadratic relationship?

c

step-by-step explanation:

c

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
