Answer:
a) rounded to the ones place and 2 significant figures.
b) rounded to tenths place and 1 significant figure.
Step-by-step explanation:
Significant figures are the number of needed place values for accuracy. Round each number according to the least number of significant figures within the problem.
A. 9 cm+2.8 cm = 11.8 cm rounds to 12 which has 2 significant figures. Round to the ones place value since 9 has the least number of significant figures.
B. 0.135 atm+0.6 atm = 0.735 atm rounds to 0.7 atm which has 1 significant figure. Zero preceding the value is not considered significant. Round to the tenths place value since 0.6 has the least number of significant figures.
Answer:
30
Step-by-step explanation:
44 - 14 = 30 more
Solution:
As given , g(x)= f(x) + k --------(1)
As also given : f(x) = 
(x+2)
g(x) = (x+5)
Putting the value of f(x) and g(x) in equation (1).
→ (x+5) = (x+2) + k
→ ![\frac{1}{3}[x+5-x-2]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%5Bx%2B5-x-2%5D)
= k
→ k = 
So , the value of k is 1.
The
formula 
, where r! is 1*2*3*...r
is the
formula which gives us the total number of ways of forming groups of r objects out of n objects.
for
example, given 10 objects, there are C(10,6) ways of forming groups of 6, out
of the 10 objects.
<span>Thus, there are C(6, 3) many ways of forming different triples out of 6.</span>
Answer: A.20
42 - 19 = 23
the difference between 42 and 19 is 23
