1. A square ABCD has the vertices A(n, n), B(n, -n), C(-n, -n), and D(-n, n). Which vertex is in Quadrant III?

andrew-mc [135]

The four quadrants and the sign of coordinates is given as follows:

Quadrant I : (n, n ) both x and y positive.

Quadrant II : ( -n,n) = x negative and y positive.

Quadrant III : ( -n,-n) = both x and y negative.

Quadrant IV: (n, -n) = x positive and y negative.

So Based on the above concept , we can say that vertex C (-n,-n) has both x and y negative and so it lies in quadrant III.

Answer is Vertex C (-n,-n)

4. What affects the size of an angle? A. Its location B. The amount of rotation of one side C. The length of its sides D. The nu

earnstyle [38]

The correct answer is
<span>D. The number of degrees in its supplement

The size of the sides and the rotation is irrelevant and would still keep the angle having the same size. The number of degrees in the supplement decides how big an angle is because the larger the supplementary angle the smaller the angle we're observing will be, and vice versa.</span>

Mac has 1/4 hour left of track practice and must be completed 8 laps around the track before he leaves which equation can be use

telo118 [61]

Answer:

(a) $Unit = \frac{1}{4}/8$

Step-by-step explanation:

Given

$Time = \frac{1}{4}$

$Lap = 8$

Required

Determine the time in each lap

The unit time in each lap is calculated by dividing the total time by the number of laps; i.e.;

$Unit = \frac{Time}{Lap}$

Substitute values for Time and Lap

$Unit = \frac{1}{4}/8$

Which equation is related to √x+10-1=x ? The square root is over the x+10

Sergio [31]

Answer:

(b) x + 10 = x^2 + 2x + 1

Step-by-step explanation:

The equation can be transformed to one without the radical by isolating the radical and squaring both sides.

$\sqrt{x+10}-1=x\qquad\text{given}\\\\\sqrt{x+10}=x+1\qquad\text{add 1 to both sides}\\\\x+10=(x+1)^2\qquad\text{square both sides}\\\\\boxed{x+10=x^2+2x+1}\qquad\text{eliminate parentheses}$

<em>Additional comment</em>

In typeset formulas, radicals, fraction bars, and superscript formatting serve to group expressions. In plain text, the only available grouping symbol is parentheses.

$\sqrt{x+1}}\ \Rightarrow$ √(x+1)
