How can an expression or process be determined for a geometric sequence?

1 answer:

8 0

Examine the given terms of the sequence. Is every term the same multiple of the previous term? If so, that multiplier is called the "common ratio," r

If "a" is the first term of the sequence, then a_n = (a)(r)^(n-1).

Something that you should remember is that the sum of the angles of a triangle add up to 180°.

Since we are given 100° and that the other two angles are equal, we can set up an equation like this:

$180=100+2x$ , where x is the 2 angles.

Doing the math, the measure of each unknown angles is 40°.

Answer:

x = -0.17 and x = -5.83

Step-by-step explanation:

We are asked to solve the quadratic equation

$x^2+6\,x+1=0$

We use the quadratic formula using a = 1, b = 6 and c = 1

for a general quadratic equation of the form: $ax^2+bx+c=0$

Then, the solutions are given by;

$x=\frac{-6+/-\sqrt{36-4\,(1)\,(1)} }{2} =\frac{-6+/-\sqrt{32} }{2}$

which produces the two following answers (rounded to two decimals):

x = -0.17 and x = -5.83
