Answer:
<h2>73</h2>
Step-by-step explanation:
The Ruler Postulate:
A distance between a number A and a number B:
AB = |B - A|
We have A = -60, and B = 13. Substitute:
|13 - (-60)| = |13 + 60| = |73| = 73
Given:
The sequence is:

To find:
The formula for the nth term in the given sequence.
Solution:
We have,

The given sequence can be written as

The sign are alternative and the absolute value of each term can be defined by the expression
, where n is a natural number.
So, the required formula is:

Therefore, the formula for nth term in the given sequence is
.

Step-by-step explanation:
Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³
Answer:
x=4
Step-by-step explanation:
19+3x=3(x-5)
do rainbows
19+3x=3x-15
subtract 19 on other side
3x=3x+4
divide out the 3s
x=4
