The height of water in a cylindrical tank is 3 m at the start of summer. The height h m at the end of t months is given by the linear function h(t) = 3 – 0.5t.
The height of water in the tank at the start of summer is 3 metres. According to the function h(t) = 3 minus 0.5t, the water level decreases by 0.5 metre every month. For example, after 1 month, the height becomes 2.5 metres and after 2 months, it becomes 2 metres. Since the height decreases by theRead more
The height of water in the tank at the start of summer is 3 metres. According to the function h(t) = 3 minus 0.5t, the water level decreases by 0.5 metre every month. For example, after 1 month, the height becomes 2.5 metres and after 2 months, it becomes 2 metres. Since the height decreases by the same amount every month, the pattern represents linear decay. The variable t shows the number of months, while h gives the water height.

See lessSuppose a plant has height 1.75 feet and it grows by 0.5 feet each month. (i) Find the height after 7 months. (ii) Make a table of values for t varying from 0 to 10 months and show how the height, h, increases every month. (iii) Find an expression that relates h and t and explain why it represents linear growth.
The plant is initially 1.75 feet tall and grows by 0.5 feet every month. After 7 months, its height becomes 1.75 plus 0.5 multiplied by 7, which equals 5.25 feet. A table from 0 to 10 months will show a regular increase of 0.5 feet each month. If t represents the number of months and h represents thRead more
The plant is initially 1.75 feet tall and grows by 0.5 feet every month. After 7 months, its height becomes 1.75 plus 0.5 multiplied by 7, which equals 5.25 feet. A table from 0 to 10 months will show a regular increase of 0.5 feet each month. If t represents the number of months and h represents the height, then the relation is h = 1.75 + 0.5t. This represents linear growth because the increase is constant every month.

See lessA mobile phone is bought for rupees 10,000. Its value decreases by rupees 800 every year. (i) Find the value of the phone after 3 years. (ii) Make a table of values for t varying from 0 to 8 years and show how the value of the phone, v, depreciates with time. (iii) Find an expression that relates v and t and explain why it represents linear decay.
The mobile phone is bought for 10000 rupees and loses 800 rupees in value every year. After 3 years, the value decreases by 800 multiplied by 3, which equals 2400 rupees. Therefore, the remaining value becomes 10000 minus 2400, which equals 7600 rupees. If t represents the number of years and v reprRead more

If t represents the number of years and v represents the value of the phone, then the expression is v = 10000 minus 800t. This represents linear decay because the decrease remains constant every year.
