For an experiment, a scientist designs a can, 20 cm in height, that can hold water. A
1 answer:
Step-by-step explanation:
The height of the water in the can is a function of time, because it depends on the time the water flows out each minute.
The height h in cm is a function f of time t in minutes since poking the hole, h= f(t)h=f(t). The expression for f(t) = 20. \frac{2}{3}^{t}f(t)=20.

The values of f -> f(0) = 20f(0)=20; f(1) = \frac{40}{3}f(1)=

The value of f(5) = \frac{640}{243}f(5)=

640
The level of water approaches close to the x-axis as time moves on. It does not completely approach zero.

<em>Question Continuation:</em>
<em>Glenn bought 3 pounds of tomatoes. He used 5/8 of them to make sauce. </em>
<em>Make an equation that shows the number of pounds of tomatoes Glenn used for the sauce.</em>
<em></em>
Answer:
Step-by-step explanation:
Given
Weight of Tomato = 3 lb
Used Proportion = 5/8
Required
Determine the portion used
To solve this we simply multiply the used proportion by the weight of the tomato bought
Represent the used portion with y.
So:
