Let T: ℝm → ℝn and S: ℝn → ℝp be linear transformations. Then S ∘ T: ℝm → ℝp is a linear transformation. Moreover, their standard matrices are related by [S ∘ T] = [S][T]. Verify the theorem above by finding the matrix of S ∘ T by direct substitution and by matrix multiplication of [S][T]. T x1 x2 = x2 −x1 , S y1 y2 = y1 + 5y2 2y1 + y2 y1 − y2

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

its an acute right triangle
