The different units of measurement (millimeters, centimeters, meters and kilometers) are used to measure from very short distances such as the amount of a medicine in a syringe to long distances between cities.
<h3>What are units of measure?</h3>
Measurement units are a series of references that are used to measure different elements and factors. Specifically, the units of measure for distance measure the distance between two points.
However, not all units of measure work for all situations, for example:
- Millimeters are a unit of measurement for very short distances such as millimeters of medication in a syringe.
- Centimeters are a unit of measurement for average distances such as the height of a person or the size of some objects.
- Meters are a unit of measurement for large distances such as the dimensions of a house.
- Kilometers are a unit of measurement for very large distances such as the distance between two cities or countries.

Answer:
15549 yrs old
Step-by-step explanation:
To find the decay constant r we use the formula
t1/2 = 0.693/r
t1/2 is the half-life 5700
5700 = 0.693/r
r = 0.693/5700 = 0.000122 per sec
For the 15% remaining from an initial value of 100%, time t is calculated from
N = Noe^(-rt)
0.15 = 1e^(-0.000122t)
we take natural log of both sides
Ln 0.15 = Ln e^(-0.000122t)
-1.897 = -0.000122t
t = -1.897/-0.000122 = 15549.18 yrs

X^2+3x
(3/2)^2=9/4 must be added to complete the square
Answer:
y=-0.078x^2+8.407x+-92.892
Step-by-step explanation:
but your x and y in desmo than go under the table do y1=ax^2 then under the 2 put a 1 than +bx1+c than you round your a b and c to the nearest thousandth than after that add a b and c then after you get your answer than but x^2 behind a than x behind b then nothing behind c hope this works for you
50 and 90 cause you can see it on the graph
