Answer:
root estimate = 1.75
error bound = 0.25
Step-by-step explanation:
f is a polynomial, so it is continuous in R (real numbers). Then you can use Bolzano's theorem.
f(0) = -3.1 < 0
f(2) = 4 - 3.1 = 0.9 > 0
Then there exists c in [0, 2], for which f(c) = 0
In the bisection method you generate a sequence 
of approximations of a root. If you have a bracketing interval [a, b], such that
f(a) and f(b) have opposite signs, then you use approximate the root as 
In this case:
Then:
The error bound is half the width of the interval [1.5, 2]
Answer:
Step-by-step explanation:
2.) −$180/year
its C
Step-by-step explanation:
- 2\sqrt5
this is the tan©
but you have to multiply by sqrt 5
so its become -2sqrt5/5
Answer:
6.7
x 2.5
2 x 6 =53
Step-by-step explanation:
1. Which polygon or polygons are regular?
A regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
Therefore your answer is:
A. equilateral triangle
C. square
2. Which polygon is always irregular?
traingle - NOT (equilateral triangle)
trapezoid - YES
square - NOT
hexagon - NOT (regular hexagon)
