Rotation 90 degrees counterclockwise about the origin​

Mathematics
1 answer:
nataly862011 [7]3 years ago
3 0

Answer:

  • Point W = (-3, 3)
  • Point X = (-3, 2)
  • Point V = (-2, 3)

<em>The rotation rule states that rotation 90° counterclockwise means (x, y) = (-y, x)</em>

<u>The new points would be equal to:</u>

  • Point W' = (-3, -3)
  • Point X' = (-2, -3)
  • Point V' = (-3, -2)

Try graphing it to see if the new points make sense<em>(because I'm not too sure :\)</em>

find the present value of an investment that is worth $19,513.75 after earning 3percent simple interest for 5.5 years
Dahasolnce [82]

Answer:

present value = $16750

Step-by-step explanation:

The simple interest formula allows us to calculate A, which is the final amount. According to this formula, the amount is given by A = P (1 + r*t), where P is the principal, r is the annual interest rate in decimal form, and t is the loan period expressed in years

simple interest formula:

t: time

P: present value

A: amount

r : anual interest

A = P (1 + r*t)

P = A / (1 + r*t)

P = 19,513.75 / (1 + 3/100 * 5.5)

P = 19,513.75/ (1 + 0.165)

P = 19,513.75 / 1.165

P = 16750

present value = $16750
