Answer:
2048
Step-by-step explanation:
Time to use recursive formula :)
Since a of 1 = 4 and -the recursive formula is
-2(a of n-1) We know that the r = -2
Convert that to explicit is
f(n) = -2 * 4^n-1
Let's use that to get the value for a of 6.
f(6) = -2 * 4^6-1
= -2 * 4^5
= -2048
-3 degrees
To find the average temperatures, you add them all together (-5 + -7 + -2 + 2 + -3 = -15) and divide that number by the number of terms added together (-15/5 = -3)
The last two numbers are five and four.
Answer:
0.16
Step-by-step explanation:
We can convert 4 / 25 to 16 / 100. Since 100 ends in 2 zeroes, we know that there will be 2 digits after the decimal point, therefore, the answer is 0.16.
Circles don't have volume, but they do have area.
The area of any circle is ...
(pi) x (the circle's radius)² .
The circle's radius is 1/2 of its diameter.
So for the circle in the question,
Radius = 30-ft
Area = (pi) x (900 square ft) = <em>2,827 square feet</em> (rounded)
