Answer:
just say something inspiring and formal
Since they are right triangles use Pythagorean Theorem.
a^2 + b^2 = c^2 where c is the hypotenuse.
a. 12^2 + b^2 = 13^2
144 + b^2 = 169
subtract 144 from both sides
b^2 = 25
take the square root of both sides
t = 5 This is also know as a Pythagorean Triple 5-12-13
b. a^2 + 9^2 = 12^2
a^2 + 81 = 144
subtract 81 from both sides
a^2 = 63
take the square root of both sides
a = √63
a = √(9 * 7)
a = 3√7
c. 6^2 + 9^2 = c^2
36 + 81 = c^2
117 = c^2
take the square root of each side
c = √117
c = √(9*13)
x = 3√13
i got 180x + 9 but idk if it is the correct answer
Answer:
$354,600
Step-by-step explanation:
The PV (present value) of a USD 100,000 outcome at the end of each year for the next four (4) years is USD 354,600.
Present value (PV) of annuity = USD 100,000 at 5% for 4 years
Present Value of Annuity of $1
= 3.546 × USD 100,000
= $354,600
