Solve for the distance between (13,55) and (61,22). Round your answer to the nearest hundredth.​
Neporo4naja [7]

Answer:

Step-by-step explanation:

position 1: (13,55)

position 2: (61,22)

distance = \sqrt{(p_{x2}-p_{x1})^{2} + (p_{y2}-p_{y1} )^{2}}

distance = \sqrt{(61-13)^{2} + (22-55)^{2}}

distance = \sqrt{(48^{2} + (-33)^{2} }

distance = \sqrt{2304 + 1089}

distance = \sqrt{3393}

distance = 58.25

You invest $600 in an account that has a annual interest rate of 7%, compounded quarterly for four years. What is the equivalent
alexandr402 [8]

Answer:

  • equivalent rate: 7.186%
  • compounded 16 times

Step-by-step explanation:

The equivalent interest rate is the rate that would have to be applied so it would earn the same amount in 1 year. It is computed from ...

  requiv = (1 +r/n)^n -1

  requiv = (1 +0.07/4)^4 -1 ≈ 7.186%

__

"Compounded quarterly" means interest is compounded 4 times per year. In 4 years, it will be compounded 4·4 = 16 times.

__

The balance in the account after 4 years is ...

  $600·(1 +.07/4)^(4·4) ≈ $791.96
