Answer:
F# Code:
let rec prefix n list =
//Extracting head and tail elements
let valHead = (Listhead list)
let valTail = (Listtail list)
// Checking n value
match n with
| 0 -> []
| _ -> [valHead] at (prefix (n-1) valTail) // Creating list recursively
//Testing function
let lstT = [1; 2; 3; 4; 5]
printfn "%A" (prefix 3 lstT)
printfn "%A" (prefix 2 lstT)
printfn "%A" (prefix 4 lstT)

Answer:
a. 30
Step-by-step explanation:
There’s a property that’s says that when 2 lines are parallel and an other is secant then if the alternate interior angle are the same . So I think that’s it I’m really sore if it’s total nonsense but I tried my best .
<span> A: y=2x 15 (or whatever variables you choose to represent the colony growth and time)
B: y=2(3.5) 15;
22 colonies
C: substitute 584 with y into the original equation, so:
584=2x 15
569=2x
284.5=x; therefore, after 284.5 hours</span> Hope this helps! :D
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.
