Answer:
the total area is 15.6 square units
Step-by-step explanation:
hello, 
you can  find the total area  dividing the shape into two known shapes
total area= area of the trapezoid +area of the semicircle
then          
step one
find the area of the isosceles trapezoid using

where
a is the smaller base
b is the bigger base
h is theheight
A is the area
let
a=2
b=5
h=4
put the values into the equation

Step two 
find the area of the semicircle
the area of a circle is given by

but, we need the area of  half circle, we need divide this by 2

 now the diameter of the semicircle is 2, put this value into the equation

find the total area
total area= area of the trapezoid +area of the semicircle

so, the total area is 15.6 square units
Have a good day.
 
        
             
        
        
        
Answer:
In a discrete probability distribution of a random variable X, the mean is equal to the sum over every possible value weighted by the probability of that value; that is, it is computed by taking the product of each possible value x of X and its probability p(x), and then adding all these products together, giving. .

I really hope this helps have a wonderful day
 
        
             
        
        
        
Answer:
Angle C measures:  
Step-by-step explanation:
When you know the length of the three sides of the triangle and not a single angle, the law of sines is of no use. You need to use the law of cosines. In your case, since you want to find angle "C", you use the following;

 
        
             
        
        
        
Using proportions, it is found that the coordinates of point B are given as follows:
A. (1.6, 0).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Point B is 3/4 of the way from AB to AC, hence:

The points are:
Then, to find the x-coordinate:

x + 2 = 3.6.
x = 1.6.
For the y-coordinate:

y + 3 = 3
y = 0.
Hence option A is correct.
