This has been a huge controversy in the vast world of mathematics. It can be 0 and it can also be 1. That's why mathematicians formally recognize it as an ambiguous number or an indeterminate number. There is no need to be worried or have a fear of this coming up on a standardized test; most test makers avoid asking controversial questions. But if they do ask it, hopefully, there will be an option saying something like indeterminate/ambiguous/undefined.

After the first term in a sequence, the ratio of each term to the preceding term is r. If the first term is a, what is the third

irinina [24]

Answer:

The 3rd term is

$ar^2$

Step-by-step explanation:

From the given information, the first term of the sequence is

$a_1=a$

The common ratio of the sequence is

$r$

The explicit formula for a geometric sequence is :

$a_n=a_1(r^{n-1})$

To find the third term, we put n=3 to get:

$a_n=a(r^{3-1})$

This simplifies to:

$a_3=ar^2$

Answer:

1). g(-9) = -81.914

2). Last option

Step-by-step explanation:

1). f(x) = x²

For x = -9

f(-9) = (-9)² = 81

g(x) = $\frac{32}{2x-17}$

g(-9) = $\frac{32}{[2(-9)-17]}$

= $\frac{32}{-35}$

= - $\frac{32}{35}$

(g - f)(-9) = g(-9) - f(-9)

= $-\frac{32}{35}-81$

= $\frac{-32-2835}{35}$

= $-\frac{2867}{35}$

= -81.914

2). The relation is not a function because this function doesn't passes a vertical line test.

Last option will be the answer.

ANSWER

B. 1

EXPLANATION

The given function is

$f(x) =\left \{ {{x^{2} +3 (if) -5 \leq x< 1} \atop {x (if) 1 \leq x \leq 5 }} \right.$

This is a piece-wise defined function.

We want to find f(1)

We substitute x=1 into f(x)=x because, 1 belongs to the interval,

1≤x≤5

f(1)=1

The correct answer is B.
