A measurement of 0.6 grams means that the 'true' answer lies between
<span>0.55 and 0.65 </span>
In general, the uncertainty in a single measurement from a single instrument is half the least precise decimal given for the instrument.
The precision for this measurement is in the tenths place.
so we take 0.1 /2 = 0.05, and divide by the measurement
<span>0.05 / 0.6 = 0.08333 = 8.3 %</span>
Answer:
-1 or 4
Step-by-step explanation:
f(x) = g(x)
-x^2 + 4x + 12=x + 8
-x^2+3x+4=0
(x+1)(x-4)=0
x=-1,x=4
You can use the cosine rule for this - you might have to change some of the letters around for it to make sense though. Hope this helps!
The 7th term of the sequence to the nearest thousandth is 223.949
<h3>What are geometric sequences?</h3>
These are sequence that increases in an exponential form.
The formula for calculating the nth term of a geometric sequence is expressed as:
Tn = ar^n-1
Given the following parameters
a = 75
r = 1.2
n = 7
Substitute the given parameter into the formula
T7 = 75(1.2)^6
T7 = 223.949
Hence the 7th term of the sequence to the nearest thousandth is 223.949
