Answer:
x times 2x divide by 2 or 2xsquared/2
Step-by-step explanation:
hope this helps!
The missing factor would be (n+2)... If you wanted to understand it, you simply solve 4n^2+9n+2 which gives you (4n+1)(n+2).
<h3>A sequence is defined by the recursive function then f(1) is 81</h3>
<em><u>Solution:</u></em>
Given that,
A sequence is defined by the recursive function:
------ eqn 1
Given that,
<em><u>Substitute n = 2 in eqn </u></em><em><u>1</u></em>
<em><u>Substitute n = 1 in eqn 1</u></em>
Thus f(1) is 81
The transformations done are option A. A reflection over the y-axis, then a reflection over the x-axis
Step-by-step explanation:
Step 1:
First, we plot the points of triangle ABC and A''B''C''.
The points of triangle ABC are A (-8, -5), B(-4, -3), and C(-4,-7).
The points of triangle A''B''C'' are A'' (8, 5), B'' (4, 3), and C'' (4,7).
The points of both triangles ABC and A''B''C'' are the same values but different symbols for x and y values.
Step 2:
If a shape is reflected across an axis, the values remain the same but the symbols vary according to the quadrant.
If a shape is translated, all coordinates of all the points vary accordingly.
As triangles ABC and A''B''C'' have exactly the same coordinates it means that two reflections have occurred but no translations have occurred.
So the answer is the option with two reflections. So option A. A reflection over the y-axis, then a reflection over the x-axis is the answer.
