Answer:

(x+1)²+(y-5.5)²=11.25

Step-by-step explanation:

1) the common view is:

(x-x₀)²+(y-y₀)²=r², where x₀, y₀ - coordinates of the centre, r - the length of the radius;

2) the coordinates of the centre can be calculated:

[tex]x_0=\frac{2-4}{2}=-1; \ y_0=\frac{4+7}{2}=5.5.[/tex]

3) the length of the radius is:

[tex]r=\sqrt{(-1-2)^2+(5.5-4)^2}=\sqrt{11.25}.[/tex]

4) if the centre is (-1;5.5) and r²=11.25, then it is possible to make up the required equation:

(x+1)²+(y-5.5)²=11.25

Answer:

The other answer is WRONG. INCORRECT. NON-RIGHT! My answer is correct, do NOT delete it.  The correct answer is (x+1)^2 + (y-11/2)^2 = 45/4.  This is how the system wants it! Want proof? I have this question and all others screenshoted for your convenience.

HERE IS PROOF YOU MORON WHO DELETED MY ANSWER

First you need to find the length. To do this, you need to find what two numbers, when doubled, equal 36. I just tried trial and error until I got to 3. So 3 times 5 equals 15. Then you have two 15's and two 3's which equals 36. Now that you know the length and width you can then find the area. The formula to find area is L*W=A. Following this the expression would be 15*3=45. So the area is 45

Her recent math test

Step-by-step explanation:

on the math test she scored 51 out of 60 points which is 51/60. this equals 0.85 which when converted to a percentage is 85%. on the science test she scored 72 out of 90 points which is 72/90. this equals 0.8 as a percentage is 80%  

Answer:

h = 40.5 m

A) 1 : 9

B) 1 : 3

C) 40.5 m

Step-by-step explanation:

Let the height of the larger triangle be h

Therefore,

[tex] \frac{10}{90}= \frac{4.5}{h}\\\\

\frac{1}{9}= \frac{4.5}{h}\\\\

h = 9\times 4.5\\\\

h = 40.5\:m\\[/tex]

A)

The ratio of the area of small triangle to the large triangle

[tex] =\frac{10}{90}=\frac{1}{9}=1 : 9[/tex]

B)

The ratio of the side length of small triangle to the side length of large triangle

[tex] =\sqrt{\frac{10}{90}} =\sqrt {\frac{1}{9}} =1 : 3

[/tex]

C) The height of the larger triangle is 40.5 m

Answer:

The vault of h is 10

Step-by-step explanation:

Since the whole triangle is 27 and the one side is 9 we know the other side must be 18. You multiply by 2 to get get from 9. That means they are similar and you just multiply 5 by 2 to get h=10.

Answer:

The ratio of apple trees to cherry trees is 14a to 1c

Step-by-step explanation:

Answer:

L = 2 4/5 feet

Step-by-step explanation:

A = L x W

6 = L x 2 1/7

divide both sides by 2 1/7

6 divided by 2 1/7 = L (is the same as multiplying by the reciprocal)

6 x 7/15 = L

L = 14/5 or 2 4/5

Answer:

There are 592 soft cover books.

Step-by-step explanation:

Let there are 8x soft cover books and 3x hard cover books. There are 222 hard cover books.

It means,

3x = 222

x = 74

Soft cover book = 8x

Put x = 74 in 8x as follows :

8x = 8(74)

= 592

Hence, there are 592 soft cover books.

Answer:

25, 21, 13, 9

Step-by-step explanation:

All you do here is plug in the X from the table to the X in the equation so,

y=29 - 4 x 1 = 25

y=29 - 4 x 2 = 21

y=29 - 4 x 4 = 13

y=29 - 4 x 5 = 9

Step-by-step explanation:

Answer:

Average rate of  change for the function for the interval (6, 12] is 500 people per year.

Option A is correct.

Step-by-step explanation:

We need to find the average rate of  change for the function for the interval

(6, 12]

The formula used to calculate Average rate of change is:

[tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}[/tex]

We are given a=6 and b=12

Looking at the graph we can see that when x=6 y= 3000 so, f(a)=3000

and when x=12, y=6000 so, f(b)=6000

Putting values in formula and finding Average rate of change:

[tex]Average \ rate \ of \ change=\frac{f(b)-f(a)}{b-a}\\Average \ rate \ of \ change=\frac{6000-3000}{12-6}\\Average \ rate \ of \ change=\frac{3000}{6}\\Average \ rate \ of \ change=500[/tex]

So, average rate of  change for the function for the interval (6, 12] is 500 people per year.

Option A is correct.
