At the beginning of a storm, a pond was 16 cm deep. during the storm, the depth increased by 1.5 cm every hour for 8 h. what graph represents the depth of the pond over this time period?

Let's assume

depth of pound over time  is h cm

time in hours as t

We are given

At the beginning of a storm, a pond was 16 cm deep

so, we get

so,

we can use formula

the depth increased by 1.5 cm every hour for 8 h

so, we get

so, we can plug these values

and we get

now, we can draw graph

Graph:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
