Answer:

42.5 units^2

Step-by-step explanation:

We can split up this shape into smaller ones.

First we can start with the large rectangle on top

We know its 9 by 3.5

9x3.5=31.5

The large rectangle is 31.5, at the end we'll add them all together

Next we can work on the small triangle on the bottom left

Area= bh/2

Both the base and height are 2, 2x2=4   4/2=2, The area of that triangle is 2

Now we can work on the triangle on the bottom right. This time the base is 5

5x2=10   10/2=5, The area of that triangle is 5

Now we need to figure out the square/rectangle at the bottom. We only know one side is 2. We can figure out the top side. Since the very top of the shape is 9, we know that the bottom side of the large rectangle also has to add to 9. We know the values 2 and 5. 2+5+x=9, the missing length that's there is 2.

Now we know the small square is 2 by 2. 2x2=4 The square's area is 4

Now we add them all up.

31.5+2+5+4=42.5

Given the parent function f(x)=x^2 describe the graph of y=(0.2x)^2
Yanka [14]
We have the following function:
 f (x) = x ^ 2
 We have the following transformation:
 Expansions and horizontal compressions
 The graph of y = f (bx):
 If 0 <b <1, the graph of y = f (x) expands horizontally by the factor of 1 / b. 
 Applying the transformation:
 y = (0.2x) ^ 2
 The factor is:
 1 / b = 1 / 0.2 = 5
 Answer:
 
b. expanded horizontally by a factor of 5

The functions r and s are defined as follows.
Arlecino [84]

Answer:

r o s(3)=?

s(x)= x²-1

x=3

s(3)= 3²-1

s(3)= 9-1

s(3)=8

r(8)

r(x)= -2x-1

x=8

r(8)= -16-1

r(8)= -17

r(s(3))= -17

I will keep uploding more picks stay tonned
Alexus [3.1K]

To find the area of a trapezoid it (top length + bottom length)/ 2 times height

Top length is 9

Bottom length is 19

(9+19)/2 x height = area

Area=168

14x height=168

Height =12
