Answer:

Range = 45

Median = 75

Step-by-step explanation:

Based on the attached box and whisker plot :

From the plot :

Maximum value = 95

Minimum value = 50

The median value can be obtained from the box and whisker plot. The median value from the plot is ; the green dotted point inside the box :

This point is marked 75.

Hence, median value = 75

Range = maximum - minimum

Range =. 95 - 50 = 45

Answer:

<u> </u>x = 90, 199.5, 270, 340.5 degrees

Step-by-step explanation:

cos2x + 2sinx = sin^2x

<em>Change cos2x to 1 - 2sin^2x:</em>

1 - 2sin^2x + 2 sinx = sin^2x

<em>Shift the terms to make it a quadratic equation:</em>

3 sin^2x - 2sinx - 1 = 0

<em>F</em><em>a</em><em>c</em><em>t</em><em>o</em><em>r</em><em>i</em><em>s</em><em>e</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>q</em><em>u</em><em>a</em><em>d</em><em>r</em><em>a</em><em>t</em><em>i</em><em>c</em><em> </em><em>e</em><em>q</em><em>u</em><em>a</em><em>t</em><em>i</em><em>o</em><em>n</em><em>:</em>

(sinx - 1)(3sinx + 1) = 0

sin x = 1 or sin x = -1/3

<em>S</em><em>o</em><em>l</em><em>v</em><em>e</em><em> </em><em>f</em><em>o</em><em>r</em><em> </em><em>s</em><em>i</em><em>n</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>:</em>

From graph of sin x, x = 90 and 270 degrees when sin x = 1.

<u>x</u><u> </u><u>=</u><u> </u><u>9</u><u>0</u><u>,</u><u> </u><u>2</u><u>7</u><u>0</u><u> </u><u>d</u><u>e</u><u>g</u><u>r</u><u>e</u><u>e</u><u>s</u>

<em>S</em><em>o</em><em>l</em><em>v</em><em>e</em><em> </em><em>f</em><em>o</em><em>r</em><em> </em><em>s</em><em>i</em><em>n</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>-</em><em>1</em><em>/</em><em>3</em>

Sin x = -1/3

Basic angle = sin inverse (1/3)

= 19.471 degrees

Since sin x < 0, x is in the 3rd or 4th quadrant

x = 180 + 19.471, 360 - 19.471

<u>x</u><u> </u><u>=</u><u> </u><u>1</u><u>9</u><u>9</u><u>.</u><u>5</u><u>,</u><u> </u><u>3</u><u>4</u><u>0</u><u>.</u><u>5</u>

Hence, <u>x</u><u> </u><u>=</u><u> </u><u>9</u><u>0</u><u>,</u><u> </u><u>1</u><u>9</u><u>9</u><u>.</u><u>5</u><u>,</u><u> </u><u>2</u><u>7</u><u>0</u><u>,</u><u> </u><u>3</u><u>4</u><u>0</u><u>.</u><u>5</u><u> </u><u>d</u><u>e</u><u>g</u><u>r</u><u>e</u><u>e</u><u>s</u>

Over what interval is the graph of y=−2 +|x− 2| increasing?
Zepler [3.9K]

Answer:

(2, ∞)

Step-by-step explanation:

An absolute value graph at (0, 0) is an up facing V shape graph. After a few transformation, according to the equation y = −2 + |x− 2|, we have our vertex at (0, - 2). It remains at up facing V graph.

x - h,

x - 2,

x - (+ 2),

h = 2

Therefore our slope is 2, with out vertex at (0, - 2). If we plot our graph, you can see that on the interval (2, ∞) the graph increases...
