Answer:
looks like A, first answer, is correct when using n such that it names what value of the sequence to use like a1 = 4 and so on.
Step-by-step explanation:
Yes because you use the distributive property
Formula for finding circumference of a circle is 2πr.
Step-by-step explanation:
- The given question says what is the circumference of a circle that is 9cm.
- As radius is required for finding circumference of a circle, the formula is 2πr.
- Therefore taking the formula and substituting radius (r)= 9 cm. We get 2πr as 2×π×9 = 18π cm OR
- If we substitute the value of π as 3.14 we will get⇒ 2×3.14×9= 56.52 cm.
- So the circumference of the given circle would be 18π or 56.52 cms.
Answer:
Step-by-step explanation:
<u>Solution 1:</u>
Notice the 
coordinate of both points are equal, meaning both points are on a vertical line. The distance between two points on a vertical line is the absolute difference of their y-coordinates. The absolute difference between 
and 
is 
.
<u>Solution 2:</u>
The distance between two points 
and 
is:
Plugging in given values, we have:
.
