The 5th term in a geometric sequence is 140. The 7th term is 35. What are the possible values of the 6th term of the sequence?
Answer:
±70
Step-by-step explanation:
Using a geometric sequence, it is found that the possible values of the 6th term of the sequence are -70 and 70.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
The nth term can also be written as a function of the mth term, as follows:
[tex]a_m = a_1q^{n-m}[/tex]
In this problem, considering that we have the 5th and the 7th term, we have that:
[tex]a_7 = a_5q^2[/tex]
Since [tex]a_5 = 140, a_7 = 35[/tex]:
[tex]q^2 = \frac{a_5}{a_7}[/tex]
[tex]q^2 = \frac{35}{150}[/tex]
[tex]q^2 = \frac{1}{4}[/tex]
[tex]q = \pm \frac{1}{2}[/tex]
[tex]\pm \frac{1}{2}[/tex] of 140 is [tex]\pm 70[/tex], hence the possible values of the 6th term of the sequence are -70 and 70.

The number 47 is decreased to 44. What is the percentage by which the number was decreased, to the nearest tenth of a percent?
Answer:
6.38298% or 6.4%
hope this helps
To calculate the percentage decrease from 47 to 44, the difference is divided by the original number and then multiplied by 100. The result is approximately a 6.4% decrease.
Explanation:To calculate the percentage decrease of the number from 47 to 44, we use the following formula for percentage decrease:
Percentage decrease = ((Original Value - New Value) / Original Value) × 100%
In this case, the original value is 47 and the new value is 44. So the calculation would be:
Percentage decrease = ((47 - 44) / 47) × 100%
Percentage decrease = (3 / 47) × 100%
Percentage decrease = 0.0638 × 100%
Percentage decrease = 6.38%
To give the answer to the nearest tenth of a percent, we round 6.38% to 6.4%. So, the number 47 is decreased by about 6.4% to become 44.

A bag contains 7 red marbles, 4 blue marbles and 5 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be green?
The probability of drawing three green marbles consecutively without replacement from a bag containing different colored marbles is approximately 0.018 when calculated step by step.
Explanation:The question is about calculating the probability of drawing three green marbles in a row from a bag that contains multiple colored marbles. To find this probability, we need to use the concept of probability without replacement.
First, calculate the probability of drawing one green marble. There are 5 green marbles out of a total of 16 (7 red + 4 blue + 5 green), so the probability is 5/16. When we draw a green marble, we do not replace it, so there are now 4 green marbles left out of 15 total marbles. The probability for the second draw is then 4/15. Lastly, for the third draw, there are 3 green marbles out of 14, making the probability 3/14.
To find the overall probability of all three events occurring, calculate the product of the individual probabilities: (5/16) * (4/15) * (3/14). This gives us 60/3360, which simplifies to 1/56. To the nearest thousandth, that is approximately 0.018.
So the probability that all three marbles drawn will be green, to the nearest thousandth, is 0.018.

Kiran, Mai, Jada, and Tyler went to their school carnival. They all won chips that they could exchange for prizes. Kiran won as many chips as Jada. Mai won 4 times as many chips as Kiran. Tyler won half as many chips as Mai.
Write an expression for the number of chips Tyler won. You should only use one variable: , which stands for the number of chips Jada won.
Answer:
Mai, Tyler Kiran,Jada ratio = 4,2,1,1Tyler is double that of Jada
So expression could be f(t) 2 x 1t x 5 = 10
Step-by-step explanation:
The expression for the number of chips Tyler won, based on the number of chips Jada won, is 2j.
Explanation:In this problem, we are asked to develop an expression for the number of chips Tyler won based on the amount Jada won. The relationships between the chips won are as follows: Kiran won as many chips as Jada (so if Jada won j chips, Kiran also won j chips), Mai won 4 times as many chips as Kiran (so Mai won 4j chips), and Tyler won half as many chips as Mai (so Tyler won 1/2 * 4j = 2j chips).
So, using j to represent the number of chips Jada won, the expression for the number of chips Tyler won would be 2j.

Desenhe em uma folha dois quadrados de lado 1dm. Trace uma diagonal em cada um e recorte-os
Answer:
The given question is
Draw two 1 dm squares on a sheet of paper. Draw a diagonal on each one and cut them out.
So, you need to draw square with sides of 1 dm. However, first, you need to transform from dm to cm.
We know that 1 decimenter (dm) equals 10 centimeters (cm).
That means the square sides are 10 centimerers long. So, you need to draw two squares like the first image attached shows.
Then, to draw their diagonals, you need to draw a line segment from one corner to its opposite corner, you should have an inclined line acroos each square. As the second image attached shows.
There you have it. Two squares of 1 dm side with on diagonal each.

What is the domain of the function y= 3Vx
Based on the graph, the domain of the function [tex]y=3\sqrt{x}[/tex] is [0, ∞].
In Mathematics and Euclidean Geometry, a domain is the set of all real numbers (x-values) for which a particular relation or function is defined.
The horizontal section of any graph is typically used for the representation of all domain values. Additionally, all domain values are both read and written by starting from smaller numerical values to larger numerical values, which means from the left of a graph to the right of the coordinate axis.
By critically observing the graph shown in the image attached below, we can logically deduce the following domain:
Domain = [0, ∞], {x|x ≥ 0}.

This net can be folded to make a square pyramid. What is the surface area of the pyramid?
Answer:
[tex]85in^2[/tex]
Step-by-step explanation:
to find the surface area we need to find the followng areas:
area of the square area of a triangle and multiply it by 4 (because there are 4 triangles)And once we have those areas, we add them to find the surface area.
Area of the square:
the formula to find the area of a square is:
[tex]a_{square}=l^2[/tex]
where [tex]l[/tex] is the length of the side: [tex]l=5in[/tex]
thus the area of the square is:
[tex]a_{square}=(5in)^2\\a_{square}=25in^2[/tex]
Area of the triangles:
the are of 1 triangle is given by
[tex]a_{triangle}=\frac{b*h}{2}[/tex]
where [tex]b[/tex] is the base of the triangle: [tex]b=5in[/tex] (the base of the triangle is the side of the square)
and [tex]h[/tex] is the height of the triangle: [tex]h=6in[/tex]
thus, the area of 1 triangle is:
[tex]a_{triangle}=\frac{(5in)*(6in)}{2}\\ a_{triangle}=\frac{30in^2}{2}\\ a_{triangle}=15in^2[/tex]
the area of the 4 triangles is (we multiply by 4):
[tex]a_{4-triangles}=4(15in^2)\\a_{4-triangles}=60in^2[/tex]
finally we add the area of the square and the area of the 4 triangles to find the total surface area:
[tex]Surface=25in^2+60in^2\\Surface=85in^2[/tex]

0.004906 × 100% = 4.9%Given the function f(x) = -2x2 + 4x - 7, find f(-4).
-55
-7
25
Answer:
f(-4)= -55
Step-by-step explanation:
We want to find f(x), or y, when x is equal to -4.
Therefore, we can substitute -4 in for x in the function.
f(x) = -2x^2 + 4x - 7
Substitute -4 in for x
f(-4) = -2(-4^2) + 4(-4) - 7
Evaluate the exponent
f(-4)=-2(16)+4(-4)-7
Multiply -2 and 16
f(-4)= -32+4(-4)-7
Multiply 4 and -4
f(-4)=-32-16-7
Subtract
f(-4)=-55
