What is the measure of Arc A U?
elixir [45]

Answer:

50°

Step-by-step explanation:

m(arc ADQ)=2 \times \angle AUQ \\   \hspace{64 pt}= 2\times \: 111 \degree \\  \hspace{64 pt}= 222 \degree \\ m(arc ADQ) + m(arc QU) \\+m(arc AU) = 360° \\  \therefore \: 222 \degree + 88 \degree +m(arc AU) = 360° \\ \therefore \: 310 \degree +m(arc AU) = 360°  \\ \therefore \: m(arc AU) = 360°  - 310 \degree  \\   \huge \red{ \boxed{\therefore \: m(arc AU) = 50°}} \\

Use technology to find points and graph the line -4y=-x+20<br><br> plotting on a graph
valina [46]

Step-by-step explanation:

First we need to isolate the y, by dividing -4 on both sides. This will give you y = 1/4x - 5.

Now you can properly graph the equation:

Since -5 is the y-intercept (the point in which the line intercepts the y-axis), we will place our first point at (0,-5) on the graph.

In order to find the next point, we will use the slope of the line and do rise/run. So we will go upwards 1 unit and to the right 4 units.

(Image of graph will be attached above⤴⤴⤴)

Hope this helps you :)

4. Find the distance between the two points. Round to the nearest tenth if necessary.
Archy [21]

Answer:

Distance = 7.8 units

Step-by-step explanation:

In coordinate geometry, the distance between the 2 points is given by

Distance = \sqrt{(x1-x2)^{2} + (y1-y2)^{2} }

where (x1,y1) and (x2,y2) are coordinates of the 2 points.

Above the 2 points given are, (-2,-1) and (3,5).

<em>x1 = -2 , y1 = -1 , x2 = 3, y2 = 5</em>

<em>Distance = \sqrt{((-2)-(3))^{2} + ((-1)-(5))^{2} }</em>

<em>Distance = \sqrt{61}</em>

<em>Distance = 7.8102 units</em>

To the nearest tenth, Distance = 7.8 units
