According to the graph, what is the value

patriot [66]

Answer:50

Step-by-step explanation:

Height = constant/width

Constant = height × width

From the graph, there are 4 points which were used to plot the graph

The Points are

Height. Width. Constant = h × w

4 2.5. 50

5 10. 50

10 5. 50

20 2.5. 50

The constant is the same at all points

David designs floor tiles. His latest design is shaped as a regular pentagon. Write a formula for the perimeter of the tile in t

alexira [117]

If one side is 3 inches, the perimeter would be 5x3 which is 15. In terms of algebra, if one side is y, then the perimeter is 5y.

The graph of the equation x^2+6x+y^2-16y=-9 is a circle. Choose True or False for each statement

BigorU [14]

Answer:

see the explanation

Step-by-step explanation:

we have

$x^2+6x+y^2-16y=-9$

Convert the equation of the circle in center radius form

Group terms that contain the same variable

$(x^2+6x)+(y^2-16y)=-9$

Complete the square twice. Remember to balance the equation by adding the same constants to each side

$(x^2+6x+9)+(y^2-16y+64)=-9+9+64$

$(x^2+6x+9)+(y^2-16y+64)=64$

Rewrite as perfect squares

$(x+3)^2+(y-8)^2=8^2$

The center of the circle is (-3,8)

The radius of the circle is 8 units

Verify each statement

A. The center of the circle is (3,-8).

False

The center of the circle is (-3,8)

B. The circle is tangent to the x-axis

True

The circle is tangent to x=5 and x=-11 and is tangent to y=0 and y=16

Remember that y=0 is the x-axis

C. The circle has a radius of 64

False

The radius of the circle is 8 units

I mark brainliest for all my questions that are answered right :) thx for helping me

The correct answer is y= 0.513(1.833)^x

Explain

We will use the equation on this form

Y=ab^x

Let’s us plug in the coordinates of first point

(X, y) , ( 9, 120)

We will have

Y=ab^x

120= ab^9

Our equation for a will be

Ab^9 = 120

ab ^9 / b^9 = 120/ b^9

a = 120/ b^9

So will have

Y= 120/ b^9 • b^x

Then we will plug in coordinates for the second point

( x,y) = ( 10, 220)

We will have

Y= 120/b^9 • b^x

220 = 120/b^9 • b^10-9

220= 120b

Divide both side by 120

B= 11/6

B= 1.833333 = 1.833

Let’s plug in the value b=11/6 to our equation for a

A= 120/b^9

A= 120/ 11/6^9

A= 120/11^9/6^9

A=120 • 6^9 / 11^9

= 0.51285 which equal to 0.513

So therefore the answer is

Y= 0.513(1.833)^x

I hope this help you
