Find 3x2+xx+1
Given x4+3x3-16x2-27x+63, show if x+3 is a factor of the quartic polynomial.
Using synthetic substitution, evaluate f(-7) if f(x)=5x4+30x3-40x2+36x+14.
If f(x)=x3-x2-11x+6 and x+2 is a given factor of the cubic polynomial, rewrite f(x) in factored form.
Use the given graph of f(x)=5x3-7x2-49x+51 to find a possible linear factor of f(x). Then use it with synthetic division to completely factor f(x).
If f(x)=(2x2-3+11)(x+4)-41, then -41 is the remainder of f(x) divided by (x+4).
True or False? Explain.
There exists a polynomial function f(x) such that f(-5)=0. For each statement say if the statement is true or false.
x-5 is a factor of f(x).
x= -5 is a zero of f(x).
x+5 is a factor of f(x).
-5 is an x-intercept of f(x).
f(x)(x+5) has a remainder of zero.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
