dem82 [27]

Answer: R(t) = 750 + 0.04t

Step-by-step explanation:

Here's the complete question:

Ebuka's monthly rent is $750. If Ebuka pays the rent late, his landlord charges 4% interest per week that the payment is late. Write a function that gives the total cost R(t), in dollars, of Ebuka's rent if he pays it t weeks late.

The above question will be represented by:

R(t) = $750 + (4% × t)

R(t) = 750 + (4/100 × t)

R(t) = 750 + 0.04t

Answer:

49.4 (rounded to the nearest tenth)

Step-by-step explanation:

You need to use the Pythagorean theorem -> a^{2} + b^{2} = c^{2} -> c^{2} is the hypotenuse

         a^{2} + b^{2} = c^{2}

(7x + 7)^{2} + 5x = c^{2}

(7x7)^{2} + (5x7) = c^{2}

      49^{2} + 35 = c^{2}

          2436 = c^{2}

         \sqrt{2436} = c

                 c = 49.355850717

                 c = 49.4 (round to the nearest tenth)

hope this helps, sorry if it is not right
