To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles.
Answer:
The maximum width must be 
Step-by-step explanation:
Let
L ----> the length of the rectangular pool
W ---> The width of the rectangular pool
we know that
so
----> inequality A
we have
substitute the value of L in the inequality A
simplify
The maximum width must be
Answer:after multiplying , u then count the number of decimal places in the question and fix it in the answer,it should be from the right to the left
Step-by-step explanation:
43644+65466=698304
Then=6.98304
Answer:
The is A as you say lol i don't know
<span>my answer to you would be that for this kind of a sequence, there is a fixed way of finding the nth term value
let's get these basics straight first:
1) Un= the nth term value
for eg. U1 = 1st term value
2) a = first term
3) d = difference
Ok now the first step to finding the nth term is finding the constant difference
in the example that you gave the constant difference is 1.5
ie 1.5 is being added on each time
now the fixed rule for finding the nth term is :
Un = a + d(n-1)
why?
because let's take a common example of a linear sequence, a sequence with a constant first term ( so called because it forms a line when drawn in a graph):
first term is a so,
a, a+d, a+2d, a+3d......a(n-1)d
(because the coefficient of d is one less than the term number)
so putting this into your q:
a = 5.5
d=1.5
Un=a + d (n-1)
Un=5.5 + 1.5(n-1)
Un=5.5 + 1.5n - 1.5
Un=4+ 1.5n
there you go it works...
for other types like quadratic cubic and geometric progression, its a totally different story
