Part a)
we have that
<span>√72
</span>√72-----> √(2*36)=√2*√36 is not 2*√36------> this is the error
√2*√36=√2*√6²-----> √2*(6)----> 6√2
<span>
</span><span>alternative method</span><span>
72 is equal to-------> 2</span>³*3²
therefore
√72-----> √[2³*3²]----->√ 2³*√3²-------> (2√2)*(3)-----> 6√2
Part b)<span>Estimate the square root of 72 to the nearest tenth
</span>
we know that
√2 is equal to 1.41
so
√72=6√2------> 6*1.41-----> 8.46----> 8.5
the answer Part b) is 8.5
Answer:
The average rate of change of the function in this interval is of 18.
Step-by-step explanation:
The average rate of change of a function in an interval from a to b is given by:
In this question:
Where x goes from 5 to 7.
This means that . So
The rate of change is:
The average rate of change of the function in this interval is of 18.
To solve this you just have to do the division from left to right. -48 divided by -4 is 12 and 12 divided by -4 is -3, which is your answer. Hope this helps!

We want to find 5 weeks to 22 days as a fraction.
Because there are 7 days n a week,
5 weeks = 5*7 = 35 days
Therefore
(5 weeks)/(22 days) = 35/22
Answer: 35/22
