Answer:
the pattern seems to be to multiply by 4 so the answer would be 524,288
Step-by-step explanation:
8×4= 32×4= 128×4= 512×4= 2048×4= 8192×4= 32768×4= 131072×4= 524,288
The 9th term of the given geometric sequence is 524288.
What do we mean by geometric progression?Geometric Progression is a series/sequence in which every term is a product of its previous term and a constant. The first term is taken as 'a' and the constant is taken as 'r'. So the series goes on like a, ar, ar², ar³, ......, arⁿ⁻¹, where arⁿ⁻¹ represents the nth term.
How do we solve the given problem?We are said that the given sequence is a geometric progression.
We take the first term as a.
∴ a = 8.
The second term is given as 32. This term is the product of the first term 'a' and the constant 'r', that is, this term is ar. To find the value of r, we divide this term by a.
r = ar/a = 32/8 = 4.
The 9th term in the sequence can be found using the formula of the nth term given by,
nth term = arⁿ⁻¹.
∴ 9th term = 8*4⁹⁻¹ = 8*4⁸ = 8*65536 = 524288.

Which operations are commutative and
associative?
addition
O subtraction
multiplication
division
Answer:
additionmultiplicationStep-by-step explanation:
When learning about commutative and associative properties, we learn that ...
a + b = b + a . . . . . addition is commutative
ab = ba . . . . . . . . . multiplication is commutative
But we also know that ...
a - b ≠ b - a . . . . . . subtraction is not commutative
a/b ≠ b/a . . . . . . . . division is not commutative
__
We also learn that ...
a + (b+c) = (a+b) +c . . . . addition is associative
a(bc) = (ab)c . . . . . multiplication is associative
And of course, ...
a - (b -c) ≠ (a -b) -c . . . . subtraction is not associative
a/(b/c) ≠ (a/b)/c . . . . . . . division is not associative
_____
However, you can use associative and commutative properties in problems involving subtraction and division if you write the expression properly:
a - (b - c) = a +(-(b -c)) = a +((-b) +c) = (a +(-b)) +c . . . . keeping the sign with the value makes it an addition problem, so the associative property can apply
(a/b)/c = (a(1/b))(1/c) = a(1/b·1/c) = writing the division as multiplication by a reciprocal makes it so the associative property can apply

PLZ HURRY! Which mapping diagram represents a function from x → y?
A function from x to y represents a situation where each x value is linked to a unique y value. This can be represented in a mapping diagram, such as with the points (1,5), (2,10), (3,7), and (4,14). Such a diagram showcases the fact that different x values trigger different y values, demonstrating the dependence of y on x.
Explanation:A function from x to y implies that when the value of x changes, it directly influences the value of y. One way to represent this is through a mapping diagram.
A mapping diagram that represents a function can be visualised as each value of x corresponding to a unique value of y. For example, refer to the following points: (1,5), (2,10), (3,7), and (4,14). Here, every x value is paired with a unique y value. When these points are plotted, there's no x value that corresponds to more than one y value, demonstrating the dependence of y on x.
Therefore, a function from x to y is represented by a mapping diagram where different x values are linked to unique y values, showing the dependency of y values on the x values.

(889 x 27) + 50 is
than 889 x 27
Final answer:
The expression (889 x 27) + 50 is greater than 889 x 27, because adding 50 to any product will always result in a larger number.
Explanation:
The student's question is asking to compare the result of the expression (889 x 27) + 50 with 889 x 27, without actually calculating the precise values.
First, let's evaluate the structure of the expressions. When we have an expression of the form (a x b) + c, adding any number c to the original product of a and b will always result in a value greater than the original product. This is a basic property of arithmetic progression.
Based on this property, we know that (889 x 27) + 50 is definitely greater than 889 x 27 because we are adding a positive number (50) to the original product, hence the sum must be larger.
In the figure, angle D measures 31⁰ and angle A measures 27⁰
1.The measurement of angle B is
A.59⁰
B.63⁰
C.90⁰
2. The measurement of angle F is
A.59⁰
B.63⁰
C.90⁰
Answer:
1)B:63°
2)A:59°
Step-by-step explanation:
1.ABC is a right triangle at C then angle ACB=90°(right angle)
Angle CAB=27°(see the given)
measure of the angles in any triangle is 180°
then angle CBA=
measure of all the angles - (measure ACB+measure CAB)
=180°-(90°+27°)
=63°
2. Same explanation of angle B:
in the right triangle DEF: angle DEF=90°
angle D=31°(given)
Then measure of angle A=180°-(angle E + angle D)
=180-(90+31)=59°

Step-by-step explanation:
Hello!
Slope is measured by lattice points on the graph, and the formula is Rise/Run.
To calculate the slope of this graph, we must find two points that intersect coordinates. I will choose coordinates (0,2) and (1,-1).
Now to find the rise, we must find the difference in the y coordinates.

HELP!! which is the measure of wx shown in the diagram below
Answer:
A. 25°
Step-by-step explanation:
We are given a circle and two intersecting lines of circle meets at s and form an angle 34° at S.
Also, we have W and X points on circle that form a minor arc and T and R makes a major arc of angle 93°.
In order to find the value of minor arc WX, we need to apply following formula:
Subtends angle on intersection of lines = [tex]\frac{Major Arc- Major Arc} {2}[/tex]
Plugging values in above formula, we get
34= [tex]\frac{93 - x }{2}[/tex]
On cross multiplication, we get
34 × 2 = 93-x
68 = 93 -x
x = 93-68
x= 25.
Therefore, measure of arc WX = 25°.Hope this helps and you understand !!!!!!
Teri bought 360 rubber band 2 make a bracelet
15% of the bands were white and the rest were red. After using 140 bands to make her 1st bracelet , 20% of the remaining bands were white
How many red bands did teri use on the bracelet
Answer:
Step-by-step explanation:
No. of white bands = 15% of 360 = (15/100)*360= 54
No.of red bands = 360 - 54 = 306
No. bands remaining = 360 - 140 = 220
No. of remaining white bands = 20% of 220= (20/100)*220 = 44
No. of remaining red bands = 220 - 44 = 176
No. of red band used = No.of red bands - No of remaining bands
= 306 - 176 = 130

1. If two nonvertical lines are parallel, what do we know about their slopes? If two lines are perpendicular and neither is parallel to an axis, what do we know about their slopes? Why must the lines be nonvertical?
Non-vertical parallel lines have equal slopes, while slopes of non-vertical, non-horizontal perpendicular lines are negative reciprocals of each other. Vertical lines are defined as having an infinite slope, thus they must be non-vertical to consider their slopes.
Explanation:When considering the slopes of lines on a graph with perpendicular axes, like the x-axis and the y-axis, we can draw several conclusions about parallel and perpendicular lines. If two non-vertical lines are parallel, their slopes are equal, because the tilt of the lines with respect to the horizontal axis is the same. For example, if we have two equations of lines in the form y = mx + b, where m represents the slope and b represents the y-intercept, parallel lines would have the same value of m.
If two lines are perpendicular and neither line is parallel to an axis, then their slopes are negative reciprocals of one another. This holds true because the product of the slopes of two perpendicular lines is -1. For example, if the slope of one line is a, the slope of the line perpendicular to it will be -1/a.
It is necessary for the lines to be non-vertical because a vertical line does not have a well-defined slope; its slope is considered infinite. Therefore, the definition of perpendicular lines in terms of slope only applies to non-vertical lines.

Number of books. 10 15 25 50
A. Yes the table represents a proportional relationship
B. The constant of proportionality is 1.2
Step-by-step explanation:
Two quantities are proportional if:
One of them is equal to the constant times the other oneIf x and y are proportion, then y = k x, where k is constant∵ Total wight in pounds ⇒ 12 , 18 , 30 , 60
∵ Number of books ⇒ 10 , 15 , 25 , 50
- Divide each two corresponding data to check if all they give
the same constant or not
∵ 12 ÷ 10 = 1.2
∵ 18 ÷ 15 = 1.2
∵ 30 ÷ 25 = 1.2
∵ 60 ÷ 50 = 1.2
- That means the total wight is equal to constant times the
number of books
∴ Total wight = 1.2 Number of books
∴ The total wight and the number of books are in a proportional
relationship
A. Yes the table represents a proportional relationship
