किसी पौधे की ऊंचाई (t=3) पर (34) सेमी और (t=9) पर (82) सेमी है। यदि वृद्धि रेखीय है तो सही मॉडल क्या होगा?
A plant's height is (34) cm at (t=3) and (82) cm at (t=9). If the growth is linear then what is the correct model?
Explanation opens after your attempt
A. (H(t)=10+8t)
Concept
The rate is \(\frac{82-34}{9-3}=8\). From (34=a+8(3)), (a=10).
Why this answer is correct
The correct answer is A. (H(t)=10+8t). The rate is \(\frac{82-34}{9-3}=8\). From (34=a+8(3)), (a=10).
Exam Tip
दर \(\frac{82-34}{9-3}=8\) है। (34=a+8(3)) से (a=10) मिलता है।
