Answer:
3
Step-by-step explanation:
(f O g) this basically means that the input x first goes trough the function g and then f. Like f(g(x)).
So when x went trough g, you got the output g(x) and then this went trough f and you got f(g(x)) = -8 = 'f(x)'.
With this in mind you can retrace your steps by first looking at what input can get -8 as an output, for f this is -4. this means g(x) = -4
Then you look at what input (this is the x you're looking for) gets you the ouput -4. Looking at the second image you'll picture see that it's the input 3.
Answer:
<u>Question 11:</u>






<u>Question 12:</u>
,
,
and 
<u>Question 13: </u>
AC and BD are perpendicular lines, and they are diagonals
Step-by-step explanation:
<u>Question 11</u>
Given


See attachment for Rhombus
Required
Determine the indicated sides
Solving (a): 
Diagonal CA divides
into 2 equal angles
i.e

So:

Solving (b): 
The angles at E is 90 degrees because diagonals AC and BD meet at a perpendicular.
So:

Solving (c): 
First, we calculate
, considering
:





To calculate
, we have:



Solving (d): 
From the rhombus

Where

So:


Solving (e): 
To do this we consider 
Using the tan formula

and 
So:



Solving (f): 
This is calculated as:

Where



<u>Question 12: Isosceles Triangle</u>
In the rhombus, all 4 sides are equal;
So, the isosceles triangle are:
,
,
and 
<u>Question 13: </u>
AC and BD are perpendicular lines, and they are diagonals
2x^-6x-4 that is the answer
Ivan's annual earnings for this bond is $45.00
<h3>What is a bond?</h3>
A bond is a pledge, made by a borrower to pay a loan taken back to the lender with an interest.
Ivan's annual interest earning would be :
= $1,000 x 4.5 %
= $45 per year
Hence, Ivan's annual earnings for this bond is $45.00
