Answer:
Step-by-step explanation:
if the base=x
length of one leg is =4x-6
length of the other leg is also =4x-6 (isosceles)
P=x+4x-6+4x-6=51
9x-12=51
9x=51+12
9x=63
x=63/9=7
x=7
Best to write this problem as shown below:
<span>562.34
-64.89
----------- First, estimate the correct answer. It would be 562-65 = 497.
Must borrow from the tenths column, because 9 is greater than 4. We end up with 5 under the 4 and 9. We must borrow again to obtain the next digit:
12-8=4, so the result is now .45
11-4=7, so the result is now 7.45
55-6=9, so the result is now 97.45.
Finally, 4-0=4, so the final result is 497.45. Compare this to the estimate (497).
Here we've had to borrow 4 times.</span>
Answer:
The signa notation to represent the first five ten f(x) is given by 
Step-by-step explanation:
Given sequence is -5, -9, 13...
Let f(x) be the given sequence and is denoted by
Let the first term be 
term be 
ie, 
To find the common difference d:
Therefore the common difference d is -4 for given sequence f(x) with 
and d=-4, the seqence f(x) is an arithmetic sequence
By defintion of arithmetic sequence
Now to find 
:
put n=4 in equation (1)
[since a=-5, d=-4]
in equation (1)
[since a=-5, d=-4]
Therefore and
Therefore 
Now to represent the sum of the first five terms of f(x) using sigma notation as below
where
