To find the angle, we will simply divide 360 by the number of sides
Number of sides = 8
That is;
Angle = 360 / 8 = 45 degree
Answer:
9(4 +5)
Step-by-step explanation:
there is a common factor of 9 in both 36 and 45
9*4 = 36
9*5 = 45
by factoring 9 out of both 36 and 45, we get 9(4 + 5)
Answer:
Step-by-step explanation:
Since we are finding a parallel line, the slopes will be the same, so the second equation will also have a slope of -5.
Then, to find the y-intercept, we can use the point given and plug in.
So the equation comes out to be
We can check by plugging in the given point again.
Volume = are base*height
32 = x^2*h --> h = 32/x^2
surface area = 4x(32/x^2) + x^2
SA = 128/x + x^2
SA' = -128/x^2 + 2x = 0
2x = 128/x^2
2x^3 = 128
x^3 = 64
x = 4
surface area minimized when length of base is 4 in.
hope this help
