What is the recursive formula for the geometric sequence with this explicit formula?
For the given geometric sequence, we have:
[tex]a_1 = 9\\\\a_n = (-1/3)*a_{n-1}[/tex]
So the correct option is B.
Which is the recursive formula?Here we have the geometric sequence:
[tex]a_n = 9*(-\frac{1}{3} )^{(n - 1)}[/tex]
To get the initial value of the geometric sequence, we just need to replace n by 1, so we get:
[tex]a_1 = 9*(-\frac{1}{3} )*(1 - 1) = 9[/tex]
Now, notice that the common ratio is (-1/3), this means that each term of the sequence is (-1/3) times the previous term.
[tex]a_n = (-1/3)*a_{n-1}[/tex]
Then the correct option is B.

One car travels 30 meters east in 5 seconds. A second car travels 42 meters west in 7 seconds. During their respective periods of travel, the cars must have had the same _______________.
The cars must have had the same Average Speed
Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.
The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:
[tex]\frac{Total distance covered by the object}{Total time taken}[/tex]
Given :-
Distance covered by A = 30 metersTime taken by A = 5 secondsDistance covered by B = 42 metersTime taken by B = 6 secondsSubstituting the given values in the formula for A and B respectively we get
Average Speed of A = [tex]\frac{30}{5}[/tex] m/s = 6 m/s
Average Speed of B = [tex]\frac{42}{7}[/tex] m/s = 6m/s
Thus the cars must have had the same Average Speed.

For choice A, order matters. This is because of the positions of first place and second place are different from one another. Since order matters, we have a permutation for choice A and can rule it out.
Choices C and D are ruled out for the same reason.
Choice B is a combination. It doesn't matter what the order of the CDs are. All that matters is the group overall rather than the individual CDs.
helpp. The Eiffel Tower in Paris, France is 1063 feet tall. If you took an elevator 3/4 the way up the tower, how far from the ground would you be in feet?
If the Height of Eiffel Tower in Paris is 1063 feet tall and we took an elevator 3/4 up the tower then we would be 797.25 feet from the ground.
Given The height of the Eiffel Tower is 1063 feet tall. We have taken an elevator that is 3/4 up the tower.
Height is the measurement of someone from head to foot or from base to top. It is the distance upward.
Height of The Eiffel tower is 1063 feet.
We have taken 3/4 up the elevator.
Then the height from ground to us can be calculated by multiplying 1063 by 3/4 which will be as under:
=1063*3/4

Answers:
Lower bound = 41.3
Upper bound = 41.5
===========================================================
Explanation:
49.15 is the smallest f can be while 49.24 is the largest it can be. Well technically we could have something like 49.2499 or 49.24999 and so on. We slowly approach 49.25 but never actually get there
So the variable f is between 49.15 and 49.25 inclusive of the first value but excluding the second value. We can write it as [tex]49.15 \le f < 49.25[/tex]
For similar reasoning, [tex]7.75 \le g < 7.85[/tex]
-----------------
If we wanted to subtract those variables and get the smallest result possible, then we need to pick values that are closest together. It might help to set up a number line.
This means we'd go for f = 49.15 and g = 7.85
The lower bound for f-g is f-g = 49.15-7.85 = 41.3
In contrast, the upper bound is when the two variables are spaced as far apart as possible. The upper bound is f-g = 49.25 - 7.75 = 41.5
Answer:
See below
Step-by-step explanation:
49.2 could be 49.15 <= f < 49.25
7.8 could be 7.75 <= f < 7.85
Lower bound of f- g would then be 49.15 - 7.85 > 41.3
upper bound 49.25 - 7.75 < 41.5
41.3 < f-g < 41.5

Find the measure of the exterior angle.
Answer:
The exterior angle is 77
Step-by-step explanation:
The measure of the exterior angle of a triangle is equal to the sum of the two opposite interior angles.
2x+11 = x +44
First we need to find x
Subtract x from each side
2x+11-x = x+44
x +11 = 44
Subtract 11 from each side
x+11-11 = 44-11
x =33
Now we can find the exterior angle
2x+11 = 2(33)+11 = 66+11 = 77
The exterior angle is 77

The completed construction of regular hexagon is shown below explain why act is a 30-60-90 triangle
In a 30°-60°-90° triangle, the length of the longer leg is √3 times the length of the shorter leg and length of the hypotenuse is twice the length of the shorter leg.
How to explain the reasonACF is a 30º-60º-90º triangle because of the following reasons;
Based on a theorem, in a 30°-60°-90° triangle, it is said that the length of the longer leg is √3 times the length of the shorter leg and length of the hypotenuse is twice the length of the shorter leg,
1 → short leg = 1
2 → hypotenuse = 2
√3 → long leg = √3
Using the Pythagorean theorem., we have that
a² + b² = c²
1² + b² = 2²
b² = 2² - 1²
b² = 4 - 1
b² = 3
√b² = √3
b = √3
Thus, in a 30°-60°-90° triangle, the length of the longer leg is √3 times the length of the shorter leg and length of the hypotenuse is twice the length of the shorter leg.
