Answer:
Step-by-step explanation:
The standard equation for a circle is given by:
Where (h, k) is the center and r is the radius.
We know that the center is (-4, 8). So, substitute -4 for h and 8 for k:
Simplify:
Now, we will need to find r.
We know that it passes through the point (-2, -1). So, we can substitute -2 for x and -1 for y and solve for r. So:
Evaluate:
Square:
Add:
So, r squared is 85.
We don’t actually have to solve for r itself, since we will have to square it anyways.
So, we have:
Substituting 85 for r squared, we get:
And we have our equation.
Xy (less than or equal to sign) 4
V = a^3
729 = a^3
9^3 = a^3
9 = a
answer. side length = 9 in
So since only 20 dollar bills and the other one is a 50
then
so we find some combos that will work
five 20's make 100
we
notice that we can only have 20's in multipules of 5 to make 100's
becauause 4 20's makes 80 and 3 20's make 60 and 2 20's make40 and none
of those add to 50 evenly to make 100's
(probably confusing but I hope you understand if you think about it)
so we have
5 20's =100
10 20's=200
15 20's=300
20
25
30
35
40
45 20's=900
50 20's=1000
so how many multiplules did we have?
10
but wait, if we havve 1000 in all 20's we still need at least one 50 so we subtract 100
900:9
answe ris 9 stacks
answer is 9 stacks or A
Answer:
(-3 ,2.5)
Step-by-step explanation:
midpoint formula is
x1+x2 y1+y2
(___ , _____ )
2 2
(-7,-2) -7 is x1 i.e the first x point and -2 is y1 1st y point
(1,7) 1 is x2 i.e the second x point and 7 is y2 the second y point
now we use input the numbers to the formula
-7+1 -2+7
(____ , --------)
2 2
we the signs are different you subtract and use sign of greater number
-6 5
__ , ___
2 2
Now you divide
and here is the ordered pair for midpoint.
(-3 ,2.5)
