The measure of an angle is 8 times the measure of its complement. tina writes an equation and finds the correct measure of each

pogonyaev

One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)

With all this information, you should have the equation:

n + 8n = 90

To solve, combine like terms to get:

9n = 90

Divide by 9 on both sides to isolate the variable n.

n = 10

Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.

Which is the graph of the function f(x) = x2 + 2x + 3?

blagie [28]

Dy/dx=2x+2

So velocity will be zero when 2x+2=0, x=-1

Since d2y/dx2=2, it has a constant positive acceleration of 2, so that when dy/dx=0 it is at an absolute minimum value for f(x), which is also the vertex.

y(-1)=1-2+3=2

So the vertex is at (-1,2), which is an absolute minimum so the parabola opens upwards.

And by symmetry we can say that f(0)=f(-2)=3 so you have another two points that you can see (-2,3) and (0,3)

Use the Polygon tool to draw an image of the given polygon under a dilation with a scale factor of 14 and center of dilation (0

puteri [66]

The points are (168, 168) , (168,56) , (112,0) , (70,112)

Given a scale factor is 14 and the center of dilation (0,0)

We need to find the Points using the scale factor and polygon tool

Now to find the new points the equation is

(old points - dilation center)*scale factor + dilation center

As we know the origin is the dilation center which simplifies to

(old point)*dilation center

(12,12) * 14 = (168,168)

(12,4) * 14 = (168, 56)

(8,0)*14 = (112, 0)

(5,8) *14 = (70, 112)

Hence the new points are (168, 168) , (168,56) , (112,0) , (70,112)

The dog spa in Champlin has an outside play area. Each play area is in

RoseWind [281]

Answer: $12,723.45

Step-by-step explanation:

Details of each play area :

The radius of circle = 18 feet long

Cost of fake grass per square foot = $12.50

Therefore,

We can obtain the Area of the play area by calculating the area of the circle:

Area of a circle = πr^2

Area = π × 18^2

Area = 1,017.876ft^2

Since the cost per square foot is $12.50

Therefore, Cost of 1,017.876 ft^2 equals

Cost per square foot × Area of play area

($12.50 × 1,017.876)

= $12,723.45
