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
HELP ASAP!!.
50/5+2- [3+9] -3+7
Please show work
Answer:
4
Step-by-step explanation:
50/5+2-[3+9]-3+7
=10+2-12-3+7
=12-12-3+7
=-3+7
=4
Answer:
the correct answer is 4
Step-by-step explanation:
first your going to calculate the parentheses
[3+9]=12
which leaves the equastion as
50/5+2-12-3+7
then multiply and divide going left-right
50/5=10
which makes the equastion
10+2-12-3+7
then add and subtract going left to right so it would be
10+2=12-12=0-3=-3+7=4

Answer:
37.5
Step-by-step explanation:
∠ABC (x) is an inscribed angle with arc AC being the arc it intercepts
An inscribed angle is equal to half the measure of its intercepted arc.
If arc AC = 75
Then x = [tex]75\frac{1}{2}[/tex]
75 / 2 = 37.5
Hence, x = 37.5
I need to find the value of x
Answer:
15°
Step-by-step explanation:
x= 89-44-30= 15°
:))
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 aquarium has the dimensions shown in the net below. What is the surface area of the aquarium?
A. 27 Square Feet
B.45 Square Feet
C. 28.5 Square Feet
D. 57 Square feet
(the top of the rectangle is 2 if you can’t see it.)
Answer:
C
Step-by-step explanation:
Answer:
D. 57 Square feet
Step-by-step explanation:
So first you do 4.5x2=9.0 then you times that by 2 so 9.0x2= 18
Next, you do 4.5x3= 13.5 then you times that by 2 so 13.5x2= 27
Lastly, you do 2x3 on one side and 2x3 on the other side. For both of those you get 6, so you do 6+6 and you get 12
Finally you do
18+27+12=57

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)
