Answer:
d. 944 mm^3
Step-by-step explanation:
The area of a circle is given by ...
A = πr² . . . . . where r is the radius, half the diameter
The area of a circle with diameter 9 mm is ...
A = π(4.5 mm)² = 20.25π mm²
The area of the semi-circular end of the prism is half this value, or ...
semicircle area = (1/2)(20.25π mm²) = 10.125π mm² ≈ 31.809 mm²
__
The area of the rectangular portion of the end of the prism is the product of its width and height:
A = wh = (9 mm)(6 mm) = 54 mm²
Then the base area of the prism is ...
base area = rectangle area + semicircle area
= (54 mm²) +(31.809 mm²) = 85.809 mm²
__
This base area multiplied by the 11 mm length of the prism gives its volume:
V = Bh = (85.809 mm²)(11 mm) ≈ 944 mm³
The volume of the composite figure is about 944 mm³.
Answer:
B should be the answer but it could but C
The value of given expression when x=-4 and y=4 is 1250.
The expression is missing in the question which is 
.
We have to solve it for x= -4 and y = 4.
Now putting the value of x and y we get,
Hence the value of given expression when x=-4 and y=4 is 1250.

Answer:
x = - 3.42443 or 6.42443
Step-by-step explanation:
The recursive formula that models the amount owed is
an = a(n-1) -75; a1 = 600.
This formula is for AFTER the first month of payment, this is why the first term is 700-100 = 600. This also means that n > 1.
