Correct Answer

A. (H(t)=11+12t)

Step 1

Concept

The rate is \(\frac{119-47}{9-3}=12\). From (47=a+12(3)), (a=11).

Step 2

Why this answer is correct

The correct answer is A. (H(t)=11+12t). The rate is \(\frac{119-47}{9-3}=12\). From (47=a+12(3)), (a=11).

Step 3

Exam Tip

दर \(\frac{119-47}{9-3}=12\) है। (47=a+12(3)) से (a=11) मिलता है।
