The endpoints of a diameter of a circle are (4,-2) and (3,6). The area of the circle in terms of pi is 65pi
First, is to get the length of the diameter by getting the distance of the two points: (4, -2) and (3, 6)
dis = sqrt( (x2-x1)^2 + (y2-y1)^2)
dis = sqrt( (3-4)^2 + (6--2)^2 )
dis = sqrt( 1 + 64 )
dis = sqrt(65)
Next, is to find the area of the circle:
A = pi * r^2
A = pi * (sqrt(65))^2
A = 204.20 square units
If the number of ice cream sandwiches is x
And the number of cookies is y
Then
1.75x + 0.75y = 12.25
and
x + y = 11
y = 11 - x
1.75x + 0.75 (11 - x) = 12.25
1.75x + 8.25 - 0.75x = 12.25
x + 8.25 = 12.25
x = 12.25 - 8.25
x = 4
if x = 4
4 + y = 11
y = 11 - 4
y = 7
x = 4, y = 7
40+5= 45
45-32=13
13/9= 1.44
1.44x2=2.89
Answer:
f(-2)=-9
Step-by-step explanation:
Since x=-2, therefore you would replace x with -2 with the equation provided.
f(-2)=4(-2)-1
f(-2)=-8-1
f(-2)=-9
Using the arrangements formula, it is found that 907,200 arrangements can be formed using the letters in the word FORGETTING.
<h3>What is the arrangements formula?</h3>
The number of possible arrangements of n elements is given by the factorial of n, that is:
When there are repeating elements, with the number of times given by 
, the number of arrangements is given by:
In this problem, the word FORGETTING has 10 letters, of which G and T repeat twice, hence the number of arrangements is given by:
