Can someone me i really need to pass this

a ≈ 5.3

Step-by-step explanation:

Using Pythagoras' theorem

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + 6² = 8², that is

a² + 36 = 64 ( subtract 36 from both sides )

a² = 28 ( take the square root of both sides )

a = ≈ 5.3 ( to the nearest tenth )

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
