if △stu ~ △xyz, which statements must be true? check all that apply.

startfraction s t over x y endfraction = startfraction t u over y z endfraction
startfraction x y over s t endfraction = startfraction su over x z endfraction
∠s ≅ ∠x
∠t ≅ ∠y
st = xy
su = xz

Step-by-step explanation:

Given:

So, from the similarity we deduct that three pair of angles are congruent: ∠S ≅ ∠X, ∠T ≅ ∠Y and ∠U ≅ ∠Z.

Similarly, sides are proportional, this means that corresponding sides are in the same relation:

We ignore the reasons why this triangles are similar, but once they are similar we can deduct all.

Therefore, the correct answers are:

ST/XY = TU/YZ

∠S ≅ ∠X

∠T ≅ ∠Y

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
