1. CBQ - Growth of plants

Exercise condition:

4 m.

Suppose a plant has height\(h\) of \(1.69 \text{feet}\) and it grows by \(0.5 \text{feet}\) each month.

(i) Find the height after \(4\) months.

3.69
1.69
4
None of the above

(ii) Find the height after \(6\) months.

4.69
1.69
4
None of the above

(iii) Find an expression that relates \(h\) and \(t\),

\(h = 0.5t +1.69\)
\(h = - 1.69 t +0.5\)
\(h = -0.5 t - 1.69\)
None of the above

(iv) Explain why it represents linear growth.

It represent linear growth because the plant grows at a non - constant rate.
It represent linear growth because the plant grows at a constant rate.
It represent linear growth because the plant grows at a variable rate.
It represent linear growth because the plant grows at a fluctuating rate.
