Frank Green purchased a home with a 10.25% rate mortgage for 25 years. His total monthly payments were $509.85. At the end of 3 years he owes the bank $55,000. Now that interest rates have gone up to 12.75%, the bank wants to renew the mortgage at this rate or Frank can pay $55,000. Frank decides to renew the mortgage, which will make his payments $610.50 a month. You can ignore the small amount of principal that has been paid.

i dont know i just need points

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
