Answer:

Hi! The trouble here is converting the minutes and seconds of the angles. Complimentary angles total 90 degrees. There are 60 minutes in one degree, so you actually have 89 degrees and 60 minutes. There are 60 seconds in a minute, so now you have 89 degrees, 59 minutes, and 60 seconds. Now you can subtract:

89-27 = 62 degrees

59-35 = 24 minutes

60-15 = 45 seconds

So the compliment is 62024'45"

The same logic happens for the supplement except you have 179 degrees 59 minutes and 60 seconds.

179-27 = 152

59-35 = 24

60-15 = 45

So the supplement is 152024'45"

Hope this helps

Which of the following would be a line of reflection that would map ABCD onto itself?

Lady bird [3.3K]

When a shape is rotated, it must be rotated over a line.

<em>The square must be reflected over line </em> $x +y = 4$ <em>, for it to be mapped onto itself.</em>

<em />

<u>The points are given as:</u>

$A = (3,1)$

$B = (3,3)$

$C = (1,3)$

$D = (1,1)$

To map the square onto itself, it must be reflected over its diagonal

The diagonals of the square are: AC and BD

<u>Using AC, we have:</u>

$A = (3,1)$ ---- $(x_1,y_1)$

$C = (1,3)$ ---- $(x_2,y_2)$

Start by calculating the slope (m)

$m = \frac{y_2 - y_1}{x_2 -x_1}$

So, we have:

$m = \frac{3-1}{1-3}$

$m = \frac{2}{-2}$

$m = -1$

The equation is then calculated as:

$y = m(x - x_1) + y_1$

This gives:

$y = -1(x - 3) + 1$

$y = -x + 3 + 1$

$y = -x + 4$

Rewrite as:

$x +y = 4$

So, the square must be reflected over line $x +y = 4$ , for it to be mapped onto itself.

See attachment for square ABCD and its line of reflection.

Consider polynomial function f(x) = (x+ 1)(x−2)(x−3).

Paladinen [302]

A) f(x) = 0 <=> x = -1 or x = 2 or x = 3;
b) x∈(-oo, -1) => f(x) < 0;
x∈(-1, 2) => f(x) > 0;
x∈(2, 3) => f(x) < 0;
x∈(3, +oo) => f(x) > 0;
