Answer:
1: Graph 4
2: Graph 2 (the first one in the third picture)
3: I got $422, so $420, is probably the correct answer.
Step-by-step explanation:
If I helped, a brainliest would be greatly appreciated!
n = 1
Here we have the following Geometric Sequence:
Where:
The first term occurs when . Next the second term occurs when , the third term when and so on. Therefore, the appropriate value of n that lies on the domain for n is
Equation of Sphere = + + - 18x - 4/3y +10z + 142/3 = 0
Data Given:
P = (x,y,z)
Distance from P to A (-3,6,3) = Twice the distance from P to B(6,2,-3)
Solution:
Find the equation of the sphere:
It is given that:
PA = 2PB
Squaring both sides:
+ + = 4 x + +
Solving the above equation:
+ + = 4 x { + + }
+ 9 + 6x + + 36 - 12y + + 9 - 6z = 4 { + 36 - 12x + + 4 - 4y + + 9 + 6z}
+ 9 + 6x + + 36 - 12y + + 9 - 6z = 4 + 144 - 48x +4 + 16 - 16y + 4 + 36 + 24z
Putting the right hand side = 0 and solving the equation:
- 4 + - 4 + - 4 + 6x + 48x - 12y +16y -6z - 24z + 9 + 36 + 9 -144 - 16 - 36 = 0
-3 - 3 -3 + 54x + 4y -30z -142 = 0
Taking (-) common
- ( 3 + 3 + 3 - 54x - 4y +30z + 142) = 0
3 + 3 + 3 - 54x - 4y +30z + 142 = 0
dividing the whole equation by 3
+ + - 54/3x - 4/3y +30/3z + 142/3 = 0
+ + - 18x - 4/3y +10z + 142/3 = 0
First answer is 4 and the next is 120
$161.88
1, 425 * 0.05 = 71.25 = yearly
71.25 / 12 = 5.94 = monthly
5.94 * 2 = 11.88 = for two months
11.88 + 150 = 161.88 = the amount he is expected to pay
Tell me if I'm wrong :)
