The endpoints of the diameter of a circle are (-7,3) and (5,1) . What is the center of the circle
Kazeer [188]

Answer:

The center is the point (-1,2)

Step-by-step explanation:

we know that

The center of the circle is equal to the midpoint of the endpoints of the diameter

so

The formula to calculate the midpoint between two points is equal to

M(\frac{x1+x2}{2},\frac{y1+y2}{2})

substitute the values

M(\frac{-7+5}{2},\frac{3+1}{2})

M(\frac{-2}{2},\frac{4}{2})

M(-1,2)

therefore

The center is the point (-1,2)

In his will, Mr. Banks left 50% of the value of his property to his
Rashid [163]

The value of Mr Banks's property was $250,000

What percentage of the property is left for charity?

The percentage of property left for charity can be determined as the 100% of the property minus all percentages given to others

% left for charity=100%-50%-22%-16%

% left for charity=12.00%

12.00% of the property=$30,000

1.00% of the property =$30,000/12

1.00% of the property =$2,500

100.00% of the property=$2500*100

100.00% of the property=$250,000

Solve for w.<br> - 2w – 14= 2(w+1)<br> Simplify your answer as much
snow_tiger [21]

Answer:

w = -4

Step-by-step explanation:

<u>Step 1:  Distribute</u>

-2w - 14 = 2(w + 1)

-2w - 14 = 2w + 2

<u>Step 2:  Add 2w to both sides</u>

-2w - 14 + 2w = 2w + 2 + 2w

-14 = 4w + 2

<u>Step 3:  Subtract 2 from both sides</u>

-14 - 2 = 4w + 2 - 2

-16 = 4w

<u>Step 4:  Divide both sides by 4</u>

-16 / 4 = 4w / 4

<em>-4 = w</em>

<em />

Answer:  w = -4

Someone told me the answer was 39?? Is this true? Why ? please help.
Ira Lisetskai [31]
The problem has the equation:

f(x) = (3) ^ (x/2)

In order to get the average increase in the number of flowers being pollinated from day 4 to day 10, then we need to use the equation substituting x with 4 to 10

f(4) = 9
f(5) = 12.59
f(6) = 27
f(7) = 46.77
f(8) = 81
f(9) = 140.30
f(10) = 243

Then add all the values and divide it by 7
 = 559.66 / 7
= 79.95

So the correct answer is 79.95
