Answer:
Step-by-step explanation:
The characteristic of geometric sequences is that any term divided by the previous term is a constant, called the common ratio. Each term in this sequence is 2 times the previous term. In this case the sequence is an=2(2)^x.
If it were an arithmetic sequence any term subtracted by the previous term would be constant, called the common difference.
Answer:
c.s.a of cone = pie r^2 + pie r l
radius = diameter/2 = 13/2
slant height (l) = 17
pie (13/2)^2 + pie 13/2 * 17
3.14 * 169/4 * 3.14 * 13/2 * 17
368246/8
= 46030
K is 1/4. So his height is 1/4 times 4 which is 1.
His new height is 1 ft
Answer:
8 and 9.
Step-by-step explanation:
Let the two unknown numbers be a and b.
When added together, they equal 17. In other words:
a + b = 17.
The <em>difference</em> between five times the first number and three times the second number is 13. In other words:
5a - 3b = 13.
We have a system of equations. We can use substitution. From the first equation, we can derive a = 17 - b. Let's substitute this in:
5(17 - b) - 3b = 13
85 - 5b - 3b = 13
-8b = -72
b = 9
a = 17 - b.
a = 17 - 9 = 8.
Thus, the two numbers are 8 and 9.
