Let us recall the Associative Property of Addition: given three real numbers
,
and
the following equality holds:
.
Let us remark that the Associative Property of Addition tells us that we can perform the sums in any order. So,
.
In the other options there was used the Commutative Property of Addition.
C. 3x^2+6 is the answer:)
Answer:
4
Step-by-step explanation:
When moving to the right of the decimal place, the place values are (in order):
- tenths
- hundredths

Therefore, the 4 is in the thousandths place.
It is given in the question that the end of a pendulum with a length of 21 cm travels an arc length of 24 cm.
So here radius is 21 cm and the arc length is 24 cm .
Now we use the arc length formula , which is

Where s is the arc length and r is the radius.
Substituting these values, we will get

And now we need to convert radian to degree, and for that we have to multiply by 
That is
