Answer:
A =166.025 ft^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) h
where (b1+b2) is the sum of the bases and h is the height
A = 1/2 (22.9)*14.5
A =166.025 ft^2
The sequence is decreasing by 3 each time
So the formula would be y =27-3(x-1)
Plug in 43
Y =27-3(43-1)
Y = 27-3(42)
Y = 27-126
Y = -99
The 43rd term of the sequence would be -99
Hope this helps :)
Answer:
Both the radius and height of the cylinder are 2.48 cm.
Step-by-step explanation:
V = π r2 h
(where r is the radius and h is the height.)
However, in the problem statement, we were told that the radius equals the height or "r = h"
So, we can rewrite the above equation as:
V = π r2*r = π r3
Now we just have to solve for r
r3 = V/π
r = (V/π)1/3
r = (48/π)1/3=2.48 cm

Answer:
A. 2x^2 +4
B. 5x^3 -4x^2 +3x -12
C. addition and subtraction of polynomials result in polynomials (closed)
Step-by-step explanation:
A. The total of the two side lengths is ...
(3x^2 -4x -1) +(-x^2 +4x +5) = (3 -1)x^2 +(-4+4)x +(-1+5) = 2x^2 +4
__
B. The length of the third side is the difference between the total for all three sides and the total for the given two sides:
(5x^3 -2x^2 +3x -8) - (2x^2 +4) = 5x^3 +(-2-2)x^2 +3x +(-8-4)
= 5x^3 -4x^2 +3x -12
__
C. Addition of the two polynomials results in a polynomial. Subtraction of the two polynomials results in a polynomial. There is nothing here to indicate the set of polynomials is not closed under addition and subtraction.
