The recursive rule for a sequence is an=an-1+7, where a1=15.What is the explict rule for this sequence

posledela

well, the recursive rule of aₙ = aₙ₊₁ + 7, where a₁ = 15, is simply saying that

we start of at 15, and the next term is obtained by simply adding 7, and so on.

well, that's the recursive rule.

so then let's use that common difference and first term for the explicit rule.

$\bf n^{th}\textit{ term of an arithmetic sequence} \\\\ a_n=a_1+(n-1)d\qquad \begin{cases} a_n=n^{th}\ term\\ n=\textit{term position}\\ a_1=\textit{first term}\\ d=\textit{common difference}\\ \cline{1-1} a_1=15\\ d=7 \end{cases} \\\\\\ a_n=15+(n-1)7\implies a_n=15+7n-7\implies a_n=7n+8$

What is the average rate of change of f over the interval [-1, 4] Give an exact number.

Sonbull [250]

Answer:

1.4

Step-by-step explanation:

The average rate of change is the "rise" divided by the "run".

rise/run = (f(4) -f(-1))/(4 -(-1)) = (0 -(-7))/(4+1)

rise/run = 7/5 = 1.4

The average rate of change on the interval [-1. 4] is 1.4.

Factor x3 – 7x2 – 5x + 35 by grouping. What is the resulting expression?

Aliun [14]

Answer:

$(x-7)(x-\sqrt{5})(x+\sqrt{5})$

Step-by-step explanation:

The given expression is

$x^3-7x^2-5x+35$

Factor the first two and the last two.

$x^2(x-7)-5(x-7)$

$(x-7)(x^2-5)$

Apply difference of two squares to the leftmost factor.

$(x-7)(x-\sqrt{5})(x+\sqrt{5})$

I need help with all of it

When you bring something up or move something down, you have to multiply the exponent by -1. So in this case, you are bringing up the exponent. Multiply 5 by -1 and your answer should be x^5/1.
