why are radioactive isotopes not useful for dating sedimentary rocks?
Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years. So in order to date most older fossils, scientists look for layers of igneous rock or volcanic ash above and below the fossil.

decide whether the sequence is artithemetic, geometric or neither 2,6,10,16
Answer:
We conclude that the sequence is NEITHER geometrc nor arithmetic.
Step-by-step explanation:
Given the sequence
[tex]2,6,10,16,...[/tex]
As we know that
An arithmetic sequence has a constant difference d and is defined by:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
Computing the differences between all adjacent terms:
[tex]6-2=4,\:\quad \:10-6=4,\:\quad \:16-10=6[/tex]
The difference is not constant
Hence, the sequence is NOT arithmetic.
NOW, let's check whether is a geometric sequence or not
A geometric sequece has a constant common ration r and is defined by:
[tex]a_n=a_0\cdot r^{n-1}[/tex]
Computing the common ratios between all adjacent terms:
[tex]\frac{6}{2}=3,\:\quad \frac{10}{6}=1.66666\dots ,\:\quad \frac{16}{10}=1.6[/tex]
The ratio is not constant
Hence, the sequence is NOT geometric.
Therefore, we conclude that the sequence is NEITHER geometrc nor arithmetic.

Answer:
$10 an hour
Step-by-step explanation:
You go to the one hour than go up to where the line is and find out what the number is
Answer:
Step-by-step explanation:
Ok, so to solve this problem, you need to find the slope of the line. You know this is what you need to find because units for slope is the y-axis units (dollars) divided by the x-axis units (hours), and your answer must be in dollars per hour based on the question. To find your slope, you use the formula (y2-y1)/(x2-x1). Basically, pick any two points on the graph. I will use (2,20) and (4,40). Now, find the change in x (4 - 2, or 2) and the change in y (40 - 20, or 20) and divide the change in y by the change in x (20/2) to get your answer.

-d^2-12d+4=-6d^2
Answer:
d=25 or d=2
Step-by-step explanation:
hope that helps!
Answer:
d=2/5 or d=2
Step-by-step explanation:
Step 1: Subtract -6d^2 from both sides.
−d2−12d+4−−6d2=−6d2−−6d2
5d2−12d+4=0
Step 2: Factor left side of equation.
(5d−2)(d−2)=0
Step 3: Set factors equal to 0.
5d−2=0 or d−2=0
d= 2/5 or d=2

Answer:
TriangleJXP = Triangle HCD
Side XJ = side HC
Side CD = side JP
Side PX = HD
Step-by-step explanation:
Looking at both of the triangles you use the lines on “top” of the side. These lines represent congruence meaning that they are similar to each other.
So looking at side JP u can see that there are two lines meaning that this is the second side that is congruent to another side, side CD.
Hope this helps.

Answer:
a. 121
b. 32100
c. 0.2
d. 400
Step-by-step explanation:
a. Quick disclaimer: If there's a decimal point on the divisor, in this case it would be .05, you have to move the decimal point until it has no decimal, in this case .05 would become 5.0 or just 5. The other number also has to have it's decimal point moved as much as the divisor, in this case two times, so it would be from 6.05 to 605. So with this in mind: 605/5 = 121
b. 96.3/.003 = 96300/3 = 32100
c. 0.12/0.6 = 1.2/6 = 0.2
d. 3.2/.008 = 3200/8 = 400

2/3 of all your books are fiction. 1/6 of those are historical fiction.
What fraction of all your books are historical fiction?
A.1/9
B.1/18
C.1/3
D.1/2
Answer:
1//18
Step-by-step explanation:
2/3 * 1/6= 1/18
You first do 2*1
Then 3*6
Answer: A. 1/9
Step-by-step explanation:
to find what fraction of all your books is historical fiction, you would multiply how the fraction of all your books that are fiction by the fraction of fictional books that are historical fiction.
this gives you 2/3 times 1/6.
from there you simply multiply the numerators (2x1=2)
and the denominators (3x6=18)
leaving you with 2/18
but that can be simplified, giving you the final answer of 1/9

Answer: Choice (3) which is the sequence –2, –7, –12, ...
Here we start with -2 and subtract off 5 each time we need a new term
-2-5 = -7
-7-5 = -12
and so on.
The notation f(n+1) = f(n) - 5 tells us "subtract 5 from the nth term, called f(n), to get the next term f(n+1)"
