A teacher needs 70 lengths of string cut to 40 cm each. If balls of string are 10 m long, how many balls will be needed.
artcher [175]
Three balls will be needed. You will need 70 pieces of the 40 cm string so 70 multiplied by 40 equals 2800. Next you need to convert the 2800 cm into meters and 2800cm= 28 meters, so if each ball of string is 10 meters long you will need 3 of them which will give you 30 meters so you will have enough with a little extra. Hope this helped!

natta225 [31]
The answer is:

The rate of change is not constant and increases then decreases over time. The height of the ball above ground gets larger until 1.25 seconds and then gets smaller after that time.


Here's how:

The rate of change of the function is defined and calculated as (refer to the statement beloew):

r = [change in height] / {change in time]


For the Table:

refer to the attached picture.

The table shows the calculations for the rate of change (r) for each interval given.


And for the Conclusion,

Refer to the table and notice that in the third ans fifth columns show that:

The rate of change is not constant and increases then decreases over time. The height of the ball above ground gets larger until 1.25 seconds and then gets smaller after that time.
