Answer:

1

Step-by-step explanation:

Method 1: Graph, then look at positive zero because time cannot be negative.

Method 2: You just want to find time when the height is zero, so if you set h at zero, you find it is a quadratic; from there you can factor, graph, or use the quadratic formula to solve.

Lily pads increase by 25% every 10 days.lf a pond starts with 22 lily pads,how many will there be after 50 days?
Fantom [35]

We conclude that after 50 days, there will be 67 lily pads.

<h3>how many will there be after 50 days?</h3>

We know that the number increases by 25% every 10 days.

In 50 days we have 5 groups of 10 days, so there will be five increases of 25%.

We know that the initial number is 22 lily pads, if we apply five consecutive increases of the 25% we get:

N = 22*(1 + 25%/100)*...*(1 + 25%/100%)

( the factor (1 + 25%/100%) appears five times)

So we can rewrite:

N = 22*(1 + 25%/100%)⁵

N = 22*(1 + 0.25)⁵ = 67.1

Which can be rounded to the nearest whole number, which is 67.

So we conclude that after 50 days, there will be 67 lily pads.
