Please help! find the common ratio of the geometric sequence. -1/4, 1/16, -1/64, 1/256,... A. 1/64 B. -1/4 C. -1/16 D. 1/16 E. 1/4
Answer:
B -1/4
Step-by-step explanation:
To find the common ratio, divide any term by the previous term.
1/16 ÷ -1/4 = 1/16 * -4 = -4/16 = -1/4
=====================================================
Explanation:
Pick any term of the sequence that isn't the first term. Divide whatever you picked by the previous term. That will compute the common ratio. This applies to geometric sequences only.
So let's say we pick on term 3 and divide it over term 2. That will get us...
[tex]r = \left(\text{3rd term}\right) \div \left(\text{2nd term}\right)\\\\r = -\frac{1}{64} \div \frac{1}{16}\\\\r = -\frac{1}{64} \times \frac{16}{1}\\\\r = \frac{-1*16}{64*1}\\\\r = -\frac{16}{64}\\\\r = -\frac{16}{16*4}\\\\r = -\frac{1}{4}\\\\[/tex]
Where r is the common ratio.
As another example, let's say we picked on term 4 and divided it over the third term
[tex]r = \left(\text{4th term}\right) \div \left(\text{3rd term}\right)\\\\r = \frac{1}{256} \div -\frac{1}{64}\\\\r = \frac{1}{256} \times -\frac{64}{1}\\\\r = \frac{1*(-64)}{256*1}\\\\r = -\frac{64}{256}\\\\r = -\frac{64}{64*4}\\\\r = -\frac{1}{4}\\\\[/tex]
We get the same result. I'll let you try dividing the second term over the first term. You should get r = -1/4 after simplifying.
-------------
Because the common ratio is r = -1/4, this means that we multiply each term by the common ratio to generate the next term.
For instance,
term 3 = (term 2)*(common ratio)
term 3 = (1/16)*(-1/4)
term 3 = -1/64
which matches with the given sequence

crikey expression to show whether it is equivalent to 3 * 9 or to 2x3x9
Answer:
See the matching below
Step-by-step explanation:
Given data
We have two expressions to match
3 * 9 and 2x3x9
3 * 9= 9*3
3 * 9=3*(4+5)
2x3x9= (2*3)*9
2x3x9= 9*3*2

What is Coordinate Geometry?By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.
As per the given data:
We are given a graph, and we have to find the reflection of the points in the graph over the y-axis.
From the graph given, the points are as as follows:
Let's assume the points as A, B, C and D
A = (-5, 4)
B = (-2, 2)
C = (1, 3)
D = (5, 1)
The reflection over the x-axis are as follows:
A' = (-5, -4)
B' = (-2, -2)
C' = (1, -3)
D' = (5, -1)
Hence, the reflection of the given points over the x-axis is:
(-5, -4), (-2, -2), (1, -3), (5, -1)

Then find the values of x and y.
Answer:
y = 4
x = 104°
Step-by-step explanation:
3y = y + 8
-y -y
2y÷2 = 8÷2
2y÷2 cancels out so
8 ÷ 2 = 4
y = 4
all sides are congruent so all angles are congruent so that means that all the angles are 104°

An exponential function is a nonlinear function
The multiplicative rate of change of the function is 1/5
From the table, we have the following ordered pairs
(x,y) = (1,2) and (2,2/5)
Divide the y values, to calculate the rate (r)
[tex]r = \frac 25 \div 2[/tex]
This gives
[tex]r = \frac 15[/tex]
Hence, the multiplicative rate of change of the function is 1/5
