p*r*t/100=si

let us replace the formula
43500*2.25*5/100=si
97875*5/100=si
489375/100=si
4893.75=si

4893.75+43500=a

Brainliest and 50 points
Annette [7]

Answer:

Using the distance formula, when I plugged in the information, the answer I got was the square root of 85. (B)

explanation:

C(x₁ , y₁) and T(x₂ , y₂) OR C(0,4) and T(-6,-3)

CT=√[(x₂ - x₁)² + (y₂ - y₁)²] =√[(-6-0)² + (-3 - 4)²]

CT=√[(36) + (49)} = CT = √85
