The formula for the area of a triangle is A=1/2bh
Answer: The answer should be 0.
Step-by-step explanation:
Remove your parenthesis: 4x times 3x times 0 times -7x²
4 times x= 4
4 times 3= 12
12 times 0= 0
0 times 7x²=0
we have been asked to find the sum of the given geometric series
A geometric sequence has a constant ratio "r" and is given by
The first term of the sequence is
Sum of the sequence is given by the formula
Plug in the values we get
On simplification we get
Hence sum
Answer:
h(n+1) = h(n) - 7
Step-by-step explanation:
Our objective is to write the expression for h(n+1) in terms of h(n) which equals -31 -7(n-1)
So we use the given formula to find what h(n+1) is:
h(n+1) = -31 -7((n+1)-1)
h(n+1) = -31 -7(n+1-1)
we now re-arrange the order of terms inside the parenthesis without combining like terms:
h(n+1) = -31 -7(n-1+1)
and use distributive property to multiply "-7" times the "+1" term and get it extracted from inside the parenthesis:
h(n+1) = -31 -7(n-1) -7
Notice that this way we were able to preserve the form of the term h(n) "-31 -7(n-1)" , and see what is the modification introduced to it when finding the term h(n+1). We now replace "-31 -7(n-1)" by "h(n)" in the above equation:
h(n+1) = -31 -7(n-1) -7
h(n+1) = h(n) - 7
And this is the recursive formula that tells us how to construct the following term of a sequence by knowing the previous one.
K=7
Hope this helps!! Can I please have brainliest?
