Write an inequality for the graph.

morpeh [17]

Answer:

Step-by-step explanation:

x $\geq$ -3 i hope this helps

since it a close circle It's either less than or equal to or greater than or equal to but since the arrow is pointing to the right it means that X is greater than or equal to negative 3

Find the area of the shaded region if the dimensions of the unshaded region are 20ft x 35ft . use 3.14 for π as necessary.

Westkost [7]

Area of the shaded region is 1397.46 square feet.

<h3>what is area of shaded region?</h3>

The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded part can occur in two ways in polygons. The shaded region can be located at the center of a polygon or the sides of the polygon.

We are to find the area of the shaded region. For that, we will divide the figure into smaller shapes, find their areas separately and then add them up.

From the given figure, we can see that there are two semi circles or say one whole circle if we combine them at the ends while 2 rectangles at the top and bottom.

Radius of circle = $\frac{20+7+7}{2}$ = 17

Area of circle = $\pi r^{2}$

= $\pi( 17)^{2}$

= 907.92 square ft.

Area of rectangles =2×(l×b)

= 2×20×35

= 490 square ft

Then,

Area of the shaded region = 907.92 +490

= 1397.46 square ft

Hence,Area of the shaded region is 1397.46 square ft.

Help me please ?! Finding coordinates of vertices of polygons. What’s A and B ?

ohaa [14]

Answer:

A is (0,-s) and B is (r, 0)

Step-by-step explanation:

Assuming this is symmetrical, point A and point B are direct opposites from the points on the same axis as them

So point A has the same distance from (0,0) as point C.

Lets say point C is (0, 5). That would make point A (0, -5) because it has the same distance from (0,0) as does C, and theyre direct opposites.

Johnny spends half of his weekly paycheck on

Morgarella [4.7K]

Answer:

$ 322

Step-by-step explanation:

x = his paycheck

x - 1/2x + 55 = 216

1/2x + 55 = 216

1/2x = 216 - 55

1/2x = 161

x = 161 * 2

x = $ 322 <===

Use the calculator to graph the function y = 2x2 25x + 3. What are the coordinates of the turning point of the graph to the near

olga2289 [7]

Use the calculator to graph the function y = $2x^2+ 25x + 3$

In the graph , the coordinates of the vertex is the turning point of the graph.

Given function is the quadratic function. For quadratic function the graph will be U shaped parabola.

There will be only one turning point for parabola

Turning point is the vertex

To find vertex we use formula x= $\frac{-b}{2a}$

y = $2x^2+ 25x + 3$

a=2, b= 35

$x =\frac{-25}{2*2} =\frac{-25}{4}$ = -6.25

Now plug in $\frac{-25}{4}$ in f(x)

$y= 2(\frac{-25}{4})^2+ 25(\frac{-25}{4}) + 3$

Take common denominator

$y= \frac{625}{8}+ (\frac{-625}{4}) + 3 =\frac{625-1250+24}{8} =-\frac{601}{8}$ = -75.125

So coordinates of turning point is (-6.25, -75.13)

The graph is attached below.
