यदि (Q(t)=320-8t), तो (Q(5)+Q(17)) किस एक (Q(k)) के दोगुने के बराबर है?
If (Q(t)=320-8t), (Q(5)+Q(17)) is equal to twice which (Q(k))?
Explanation opens after your attempt
C. (Q(11))
Concept
In a linear model the midpoint of (5) and (17) is (11). Therefore (Q(5)+Q(17)=2Q(11)).
Why this answer is correct
The correct answer is C. (Q(11)). In a linear model the midpoint of (5) and (17) is (11). Therefore (Q(5)+Q(17)=2Q(11)).
Exam Tip
रेखीय मॉडल में (5) और (17) का मध्य (11) है। इसलिए (Q(5)+Q(17)=2Q(11)) होता है।
