A plant's height is (H(t)=24+5t) cm. What will be the height at (t=4)?

Answer and explanation

Correct answer: 44 cm

Given \(H(t)=24+5t\). Substituting \(t=4\), \(H(4)=24+5(4)=24+20=44\) cm. Therefore, 44 cm is correct. The value 49 cm would result from an error in multiplication or addition. Exam tip: To evaluate a linear expression, substitute the given value for the variable and calculate step by step.
