Answer:
14
Step-by-step explanation:
the four smaller rectangles of each of the corners: 2*1=2. since there are four of them, 2*4=8
the middle, larger rectangle: (6-2-2)*(1+1+1) = 2*3 =6
add small and big rectangles: 8+6 = 14
I think it's b I hope these helpes
The cost function is a quadratic. The basic form of a quadratic equation is ax^2 + bx + c = 0. You must find the values of the coefficients a, b and c.
Use the given data to construct 3 simultaneous linear equations in x:
5 = a(2)^2 + b(2) + c
143 = a(4)^2 + b(4) + c
869 = a(10)^2 + b(10) + c
You must solve for a, b and c and then write the quadratic equation
y = ax^2 + bx + c that governs the production costs. Then let x=7 and calculate y, which is the figure you want.
Using matrices, I found that a=6.5, b=30 and c=-81.
Can you now write the quadratic equation and evaluate it at x = 7?

Answer:
16.7
Step-by-step explanation:
Following SOHCAHTOA, we see that Sine = Opposite/Hypotenuse is appropriate for this question. Since the sine of 33 is approximately 0.54, we see that the Opposite(9) / Hypotenuse(x) should be 0.54.
9 / x = 0.54
9 = 0.54x
9/0.54 = x
16.7 = x
