\text{The explicit rule of geometric sequence}\\\\a_n=a_1 r^{n-1}\\------------------------------\\\text{We have the recursive form}\ a_1=3,\ a_n=\dfrac{1}{2}\cdot a_{n-1}.\\\\\text{Therefore}\ r=\dfrac{1}{2}.\ \text{Substitute:}\\\\\boxed{a_n=3\left(\dfrac{1}{2}\right)^{n-1}}

Kobe Bryant is shooting free throws. Making or missing free throws doesn't change the probability that he will make his next one
aliina [53]

Answer:

b)0.83^6

probability of Kobe Bryant making all of his next 6 free throw attempts

=probability of Kobe Bryant making first free throw attempts x

probability of Kobe Bryant making second free throw attempts x

probability of Kobe Bryant making third free throw attempts x

probability of Kobe Bryant making fourth free throw attempts x

probability of Kobe Bryant making fifth free throw attempts x

probability of Kobe Bryant making sixth free throw attempts

= P(make 1) x P(make 2nd) x P(make 3rd) x P(make 4th) x P(make 5th)x P(make 6th) = 0.83^6

What is the scale factor for the transformation of the pre-image<br> STAR shown in the graph?
Olin [163]

Option third is correct enlarged by a factor of 4 because the distance between two dots is 1.

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a star showing in the picture.

We are considering the small star as the original image.

And the big star is the pre-image.

As we know,

The scale factor =

(length of the big star in the x-direction from the origin)/(length of the small star in the x-direction from the origin)

The distance between two dots is 1.

Scale factor = 8/3

As the scale factor is greater than 1 it means the image will be enlarged.

Thus, option third is correct, enlarged by a factor of 4 because the distance between two dots is 1.

I rlly need help im struggling in math rn and i need to study for regents pls answer
Rufina [12.5K]
The answer is choice 4. You can do this to ways. One is factoring. To factor you do 2x^2-2x+3x-3. 2x(x-1)+3(x-1). (2x+3)(x-1). You could do that or multiply each answer choice out. Either way you get answer choice 4.
