Question

Plants A boojum is a very slow-growing cactus. One fifty-year-old boojum is 1.5 meters tall and has been growing about 0.03 meter each year. Assume the growth pattern continues.

a. Write an expression for the height in meters of the boojum y years from now.

b. Apply How tall will the boojum be in 50 years?

Short answer

(a)The value of the expression, for height of boojum in meters for y years from now,$0.03\times y=0.03y\text{meters}$

(b)The value of the expression, for how tall the boojum be in the50 years,$0.03\times y=1.5\text{meters}$

Step-by-step solution

Step-1 – Order of operations

To evaluate any expression involving more than one operation, follow the below order of operations:

• First evaluate expressions inside grouping symbols like parentheses ( ) or brackets [ ].
• Evaluate the exponents.
• Perform Multiplication and division from left to right.
• Perform addition and subtraction from left to right.

Step-2 – Given

Consider, the expression for height of boojum in meters for y years from now,$0.03\times y$

Step-3 – Calculation

The value of the expression, for height of boojum in meters for y years from now,$\begin{array}{l}0.03\times y\\ 0.03\times y=0.03y\end{array}$

Therefore, the value of the expression, for height of boojum in meters for y years from now,$0.03\times y=0.03y\text{meters}$

Step-2 – Given

Consider, the expression for height of boojum in meters for y years from now,$0.03\times y$

Step-3 – Calculation

The value of the expression, for how tall the boojum be in the50 years,

$\begin{array}{l}0.03\times y\\ 0.03\times y=0.03\times 50\left[\text{substitute}y\text{for50}\right]\\ 0.03\times y=1.5\left[\text{multiply}\right]\end{array}$

Thus, the value of the expression, for how tall the boojum be in the50 years is 1.5 meters.
