Complete the recursive formula of the geometric sequence -0.6, 3, -15, 75, ...
lara [203]

Answer:

\boxed{Un = 3(-5)^{n - 2}}

Step-by-step explanation:

We know that

a = -0,6 = -\frac{3}{5} and r = \frac{3}{-0,6} = -5

.

So

Un = ar^{n - 1}

Un = (-\frac{3}{5} )(-5)^{n - 1}

Un = (3)(-5)^{-1}(-5)^{n - 1}

Un = 3(-5)^{n - 2}

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms. Third-degree, with zeros of −3
RSB [31]

Answer:

\Large \boxed{-\dfrac{5}{4}(x+3)(x+1)(x-2)}

Step-by-step explanation:

Hello,

Based on the indication, we can write this polynomial as below, k being a real number that we will have to identify (degree = 3 and we have three zeroes -3, -1, and 2).

   \Large \boxed{k(x+3)(x+1)(x-2)}

We know that the point (1,10) is on the graph of this function, so we can say.

k(1+3)(1+1)(1-2)=10}\\\\4*2*(-1)*k=10\\\\-8k=10\\\\k=\dfrac{10}{-8}=-\dfrac{5}{4}

Then the solution is:

\large \boxed{-\dfrac{5}{4}(x+3)(x+1)(x-2)}

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
