Answer:
D. 420
The area of a triangle is

half of(base× height)
10×16= 160
160÷2=80
That is the surface area of ONE triangle.
multiply 80 by 4 to get 320
then find the surface area of the square by doing length×width to get 100
Finally add them together
320+100=420
The functions have been arranged in ascending order from the least to the highest value below
- 3x
- 3x + 8
- x^2
- x^2 + 6
- 4^x
- 4^x + 3
<h3>What is meant by ascending order?</h3>
This is used in mathematics as well as other disciplines to explain the order by which values are arranged. This arrangement is usually done in such a way that the smallest value would come first and continue to climb till we get to the value that is the highest.
The values here have been arranged in this order in such a way that the smallest values came first while the bigger values are at the end.

Answer:
OPTION C: Sin C - Cos C = s - r
Step-by-step explanation:
ABC is a right angled triangle. ∠A = 90°, from the figure.
Therefore, BC = hypotenuse, say h
Now, we find the length of AB and AC.
We know that: 
and 
Given, Sin B = r and Cos B = s
⇒ 
⇒ 
Hence, the length of the side AC = rh
Now, to compute the length of AB, we use Cos B.

⇒ 
Hence, the length of the side AB = sh
Now, we are asked to compute Sin C - Cos C.

⇒ 

= s
Sin C = s


⇒ Cos C = 
Therefore, Cos C = r
So, Sin C - Cos C = s - r, which is OPTION C and is the right answer.
Inequalities are used to show the relationship between unequal expressions
- <em>The set notation of (5) and (6) are: </em>
<em> and </em>
<em>.</em> - <em>See attachmen</em>t for the graphs
The following should be notated when plotting the graph of an inequality
- < and > are represented with open circles, while
and
are represented with closed circles - The arrows of
and
point to the left, while the arrows of
and
point to the right.
So, we have:

Rewrite as:
The graph of
will point to the right, and it will use an open circle

Split the inequality:
and 
<em>It is not possible for -6 to be less than x and at the same time, x is greater than or equal to -2.</em>
<em />
Hence.
cannot be represented on a graph

Split the inequality:
and 
means that -4 is less than x or x is greater than -4.
So, we have:
and 
If
and
, then we make use of
because it contains more values of x.
The graph of
will point to the right, and it will use an open circle
