F(6) = 6(5 - 6) = 6(-1) = -6
f(6.1) = 6.1(5 - 6.1) = 6.1(-1.1) = -6.71
f'(6) ≈ (-6.71 - (-6))/(6.1 - 6) = -0.71/0.1 = -7.1
Answer:
10
Step-by-step explanation:
We know that interior plus exterior angles add to 180.
1/5 of 180 = 36
36 degrees = exterior angles
180-36=interior angles
180-36=144
To find the number of sides of a polygon you have to do 360/exterior angles
360/36=10
<span>8 is a common factor for all coeficients so we factor it out first: 8(2x^2 + x + 4). Now we have to check can we factor the quadratic equasion in the brackets to linear factors. To do that we need to check is the discriminant D=b^2 - 4ac > 0 where a=2, b=1 and c=4. When we insert our numbers, we get: D= -31. We see that D < 0 so 8(2x^2 + x + 4) is the completely factored form.</span>
Y = mx + b
y - b = mx
(y - b) / x = m
so its : m = (y - b) / x.....or m = (y/x) - (b/x)
