1st
Make a right triangle with legs 5, 12, and hypotenuse D. D is the distance you need.
Pythagorean Th
25 +144 = D^2
169 = D^2
D = 13
2. Plug in all the points...
B, D, F work
Let's start by first remembering what a "geometric sequence" is. A geometric sequence is a sequence of numbers that multiply by the same number each time. For example,
2, 4, 8, 16
is a geometric sequence since each number is multiplied by 2 from one to the next, but
2, 4, 6, 8
is NOT a geometric sequence. We are adding 2 each time, but not multiplying, so it doesn't count. We have to be multiplying to have a geometric sequence.
[A] Let's look at A, are we multiplying by the same thing?
6*3 = 18
18*3 = 54
54*3 = 162
162*3 = 486
Yes! We are multiplying by 3 each time. This is a geometric sequence!
[B] Are we multiplying by the same thing?
2*3/2 = 3
3*3/2 = 9/2 which is not 5.
NOPE
[C] Are we multiplying by the same thing?
2*5/2 = 5
5*5/2 = 25/2 which is not 8
NOPE
[D] Are we multiplying by the same thing?
-4*1/2 = -2
-2*1/2 = -1
-1*1/2 = -0.5
-0.5*1/2 = -0.25
-0.25*1/2 = -0.125
Yep, we are multiplying by 1/2 each time! This is a geometric sequence!
This is in the 3rd quadrant, so -12 is the adjacent side of the 5,12,13 triangle.
Cot(theta) = -12/(-13) = 12/13
Answer:
x=4
Step-by-step explanation:
first lets move it over
3x = 12
x=4
check:
14*4 = 56
-5 =
51
7+ 11x=
11*4 = 44
44+7 = 51
51 = 51
hope this helps :D
D. $ 3x30
Since $2.87 round to $3 and 27 rounds to 30 you would multiply the cost of each bag ($3) by the amount of people (30) meaning your estimate would be 30x3 which equals $90
