Answer:
\/226 is te exact form
Step-by-step
/(x2-x1)^2 +(y2-y1)^2
/((-8)-7)^2 + ((-5)-(-4))^2
/226
Decimal form is 15.03329637
So 15.03
Step-by-step explanation:
1/2(7x+48) = 7x ÷2 +48÷2 = 7x÷2 + 24
and
-(1/2x-3)+4(x+5) = 7x ÷2 + 46÷2 = 7x÷2 +23
The required simplified expression for 9(m - 9) - 4(10m + 2) is -31m - 90.
Given that,
To rewrite in simplest terms: 9(m-9)-4(10m+2).
<h3>What is simplification?</h3>
The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Question asked to simplify the term 9(m-9)-4(10m+2).
= 9(m - 9) - 4(10m + 2)
= 9m - 81 - 40m - 8
= -31m - 90
Thus, the required simplified expression for 9(m - 9) - 4(10m + 2) is -31m - 90.

0.003 is one tenth of .03
The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r), s(n)=nth sum, a=initial value, r=common ratio, n=term #
In this case we are told that a=6 and r=1/3 so:
s(n)=6(1-(1/3)^n)/(1-1/3)
s(n)=6(1-(1/3)^n)/(2/3)
s(n)=9(1-(1/3)^n), so the sum of the first 5 term is:
s(5)=9(1-(1/3)^5))
s(5)=9(1-(1/243))
s(5)=9(242/243)
s(5)=2178/243
s(5)=242/27
s(5)=8 26/27 ...if you wanted an approximation s(5)≈8.96 to the nearest hundredth...
