We are given the statement that the strength, S, of a beam of width w andheight h is proportional to wh2. hence using k as the proportionality constant, the equation is S = k wh2. the exact width and height can be determined by applying optimization to the problem. optimization is taking the first derivative of an equation and equating then to zero
Are those answer options or the side lengths? And where is the trapezoid?
Answer: m = n-1
Step-by-step explanation:
7m+2 = 7n-5
7m = 7n-5-2
7m = 7n - 7
Divide both sides by 7,
m=n-1
(4x+5)(-3x-1)=
-12x²-19x-5
So, you answers would be:
A. (-16x²+10x-3) + (4x²-29x-2)
D. (2x²-11x-9) - (14x²+8x-4)

Answer: 376.8m^2
Step-by-step explanation:
The surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, given as 3.14; h is the height, given as 7m and r is radius, given as 5m.
Therefore, rh = 5 x 7= 35m while r^2 =5×5 = 25m.
Slot the values into the formula:
V= 2 x3.14 (35) + 2 x 3.14 (25)
V = (6.28 × 35) + (6.28 x 25)
V = 219.8 + 157
V= 376.8m
I hope this helps
