Consider the sequence 16,-8,4,-2,1,

1 answer:

5 0

This is a geometric progression pattern with the common ratio of negative 0.5.

The next three would be -0.5, followed by 0.25, followed by -0.125

Answer:

${f}^{ - 1} (x) = 9x + 18$

Step-by-step explanation:

$f(x) = \frac{1}{9}x - 2$

$y = \frac{1}{9} x - 2$

$x = \frac{1}{9}y - 2$

$x + 2 = \frac{1}{9}y$

$9x + 18 = y$

${f}^{ - 1} (x) = 9x + 18$

Which property is shown?

melisa1 [442]

We are given a tasked to find the geometric property of a triangle that satisfies the given conditionm∠abc=m∠cbd, then m∠cbd=m∠abc.

It can be observed that if the first value is equal to the second value then the second value is also equal to the first value. This kind of characteristics describes the Symmetric Property.

Is (x-1) a factor of 2x3 - 15x2 + 22x + 15

Advocard [28]

Answer:

Step-by-step explanation:

If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?

f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15

f(1) = 2 - 15 + 22 + 15

f(1)= 24.

No the result is not zero. So x - 1 is not a factor.

However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.

The numbers that do make this zero are -0.5, 3, 5

Which mean that the factors are (2x+1)(x-3)(x - 5)
