Rina8888 [55]

Answer:

A. 16.12 ft  B.  9.64 ft

Step-by-step explanation:

For both of these, you need Pythagorean's Theorem because we have right triangles.  In part A, we are given 2 legs and are asked to find the length of the hypotenuse:

14^2+8^2=PR^2 and

196+64=PR^2

and PR = 16.12 ft

In part B, we are given the length of the hypotenuse and side PQ remains the same:

14^2+QR^2=17^2 and

196+QR^2=289

QR^2=289-196 so

QR = 9.64 ft

Suppose A and B are square matrices of the same size. Which of the following are necessarily true?
kiruha [24]

Answer:

c. (A + B)^2-A^2 + 2AB + B^2

Step-by-step explanation:

Given that:

a.

(A-B)^2 = A^2 - 2AB + B^2

If and only if AB = BA

Then;

(A-B)^2 = (A -B ) (A - B)

(A-B)^2 = A^2 - AB-BA + B^2    (FALSE)

b.

(AB)^2=A^2B^2

on true if any only if AB =BA

(AB)^2= (AB) (AB)

c.

(A+ B)^2 =  A^2 + 2AB + B^2

(A+ B)^2 = (A + B) (A+B)

(A+ B)² = A × A + A × B + B × A + B × B

(A+ B)^2 = A^2 + A*B + B*A + B^2

This is true

What can be concluded about the polygon?
cupoosta [38]

You can conclude that the sides are parallel because the slope of the opposites are the same. (Second option).


You can conclude that the polygon is a rectangle since it has 4 90º angles, and 4 sides, each one parallel to the other and of the same lenght as it's parallel. (Last option).


Answer:


\boxed{\bf~The~second~and~last~options~are~correct.}



Hope it helped,


Happy homework/ study/ exam!
