Answer:

Step-by-step explanation:
The area of trapezoid is given by the formula:

Where
A is the area
b_1 is base 1
b_2 is base 2, and
h is the height
Looking at the figure, base 1 is the left line which goes from y = 3 to y = 3, so 6 units. Also, base 2 is the right line which goes from y = -3 to y =5, so 8 units.
The height is the horizontal distance in the middle, which goes from x = -2 to x = 3, so 5 units. Hence area of trapezoid is:

Now, area of semicircle is:

Where
A is the area
r is the radius
Looking at the figure, the diameter (twice radius) goes from y = -3 to y = 3, so 6 units. But radius is half of that, so 3 units. Hence area of semicircle is:

Total area of the figure is 
Answer:
a1 = 1
an = an-1 * -5

Answer:
C $0.40
Step-by-step explanation:
to find how much one pound of potatoes is, you have to divide the the cost of the bad by the number of pounds ($3.98 divided by 10 pounds)
$3.98 : 10 = $0.398 = $0.40
Answer:
52
Step-by-step explanation:
f(6)= (8 × 6) + 4
= 48 + 4
= 52
