Step-by-step explanation:
-2x -6 = -2x -2 -4
-2x -6 = -2x -6
Collect like terms
-2x +2x = - 6 +6
0 = 0
From this, you can choose your correct answer
Answer: C) all real numbers except n Pi, where n is any integer
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Question 1</u>
<u />
Given integral:
Using <u>Integration by parts</u>:
Therefore:
<u>Question 2</u>
<u />
Rewrite the given integral:
Use the trig identity to rewrite :
<u>Integration by substitution</u>
Therefore:
Finally, substitute back in:
To answer this question, first you need to find the (g°f) function. It will be found by inserting the f(x) into g(x). It should be:
<span>g(x) = x^4
</span><span>(g°f)(x)= (2x+8)^4
</span><span>(g°f)(-3)= (2*-3+8)^4
</span><span>(g°f)(-3)= (8-6)^4= 2^4= 16</span>
Answer:
The scale factor is 4
Step-by-step explanation:
This question requires an attachment; I'll answer this question using the attached figure
From the attachment
<em>Length OA = 3 units</em>
<em>Length OA' = 3 units + 9 units</em>
<em>Length OA' = 12 units </em>
<em></em>
Scale Factor is calculated as follows;
Given that the original shape is ABC, the original side will be OA
Hence, Original Side = 3 units
New Side = OA' = 12 units
The formula becomes
<em>Hence, the scale factor is 4</em>
