The geometric sequence 128,32,8,2 has a common ratio
The recursive definition of the geometric sequence is [tex]a_n = 4a_{n-1}[/tex] where a1 = 128
How to determine the recursive definition?The geometric sequence is given as:
128,32,8,2
Start by calculating the common ratio (r)
[tex]r = \frac{a_{n}}{a_{n-1}}[/tex]
Substitute 2 for n
[tex]r = \frac{a_2}{a_1}[/tex]
Substitute known values
[tex]r = \frac{128}{32}[/tex]
Evaluate the quotient
[tex]r = 4[/tex]
Substitute 4 for r in [tex]r = \frac{a_{n}}{a_{n-1}}[/tex]
[tex]4 = \frac{a_{n}}{a_{n-1}}[/tex]
Cross multiply
[tex]a_n = 4a_{n-1}[/tex]
Hence, the recursive definition of the geometric sequence is [tex]a_n = 4a_{n-1}[/tex] where a1 = 128

A cashier samples the transaction of every 10th person who goes though the line at a craft store out of 40 people, 32 used a coupon. If 750 people go to this store each day, how many people would you expect to use a coupon?
If 750 people go to this store each day, 75 people would be sampled and 60 people would be expected to use a coupon
What is probability?Probability is the likelihood of occurrance of an event. It is given by:
Probability = number of occurrence / total number of possible occurence
A cashier samples the transaction of every 10th person who goes though the line at a craft store out of 40 people, 32 used a coupon.
Probability of using coupon = 32/40 = 0.8
Hence if 750 people go to this store each day, number of people sampled = 75.
Number of people expected to use the coupon = 75 * 0.8 = 60
If 750 people go to this store each day, 75 people would be sampled and 60 people would be expected to use a coupon

The total weight of a delivery truck is equal to the weight of the empty truck plus
the weight of the packages. The truck weighs 8,200 lb when empty.
Write an equation that shows how to use the total weight of the truck to
find the weight of the packages. Show your work.
The weight of the package is an illustration of a linear function
The total weight of the package is p = 8200 - T
How to determine the total weight of the package?The given parameter is:
Weight of empty truck = 8200 lb
Represent the total weight of the truck with T, and the weight of the package with p.
So, we have:
T = 8200 + p
Make p the subject
p = 8200 - T
Hence, the total weight of the package is p = 8200 - T

The diagram shows two straight lines. Both lines intersect at point A. У y = 4x A х A y = -2 Identify the coordinates of point A. (3-2) (-2,-5) , -8 (-2,2) () (2-2 ) A B D
Answer:
Point [tex]A[/tex] is at [tex](-1/2,\, -2)[/tex].
Step-by-step explanation:
The intersection [tex](x,\, y)[/tex] of two lines in a plane could be found by solving a linear system of two unknowns ([tex]x[/tex] and [tex]y[/tex]) and two equations (one for each line.)
In this question, the equation of the two lines are [tex]y = 4\, x[/tex] and [tex]y = -2[/tex], respectively. The corresponding system of equations would be:
[tex]\left\lbrace \begin{aligned} & y = 4\, x \\ & y = -2\end{aligned} \right.[/tex].
Solve this system for [tex]x[/tex] and [tex]y[/tex]:
[tex]y = (-2)[/tex].Substitute [tex]y = (-2)[/tex] into the first equation and solve for [tex]x\![/tex]: [tex]x = (-1/2)[/tex].Therefore:
[tex]\left\lbrace \begin{aligned} & x = -\frac{1}{2} \\ & y = -2\end{aligned} \right.[/tex].
Thus, the coordinates of this intersection [tex](x,\, y)[/tex] would be [tex](-1/2,\, -2)[/tex].

Find the missing vertical angles.
Answer:
L1 = 113°
L4 = 67°
Step-by-step explanation:
L1 + L2 = 180°
L1 = 180° - L2
L1 = 180° - 67°
L1 = 113°
L3 + L4 = 180°
L4 = 180° - L3
L4 = 180° - 113°
L4 = 67°
Proof-
Combination of L1,L2,L3 and L4 should be 360°
113°+67°+113°+67° = 360°

Sanjay is standing on level ground 70 meters away from a flag pole. The angle of elevation to the flagpole is 38 degrees. The height of Sanjay's eyes are 167cm from the ground. How tall is the flag pole in meters?
The height of the pole is 53 m
What is the height of the pole?The angle of elevation is the angle formed between a horizontal line and a line of sight or an upwardly inclined line from an observer to an object or point. It is used to describe the angle at which an object is viewed from a particular position
Let the height of the pole be x
We know that;
Tan 38 = 1.67 + x/70
Tan 38 * 70 = 1.67 + x
x = (Tan 38 * 70 ) - 1.67
x = 53 m
Thus we can see that the height of the pole is about 53 m

Given that points Q, R, S lies between O and P meaning that the points are between 0 and 3
OQ = QR = RS = SPDraw a number line and find three equal points
so points:
Q = 0.75R = 1.5S = 2.25Answer:
[tex]\sf Q=\dfrac34, \ R=\dfrac32, \ S=\dfrac94[/tex]
Step-by-step explanation:
Given information:
O = 0P = 3Points Q, R and S are between O and POQ = QR = RS = SPTherefore, there are 4 segments of equal distance between points O and P.
Length of OP = 3 - 0 = 3
⇒ Length of each segment = 3/4
To find the point of Q, R and S, add 3/4 to each point:
Point O = 0
⇒ Point Q = 0 + 3/4 = 3/4
⇒ Point R = 3/4 + 3/4 = 3/2
⇒ Point S = 3/2 + 3/4 = 9/4
Point P = 9/4 + 3/4 = 3
Therefore,
[tex]\sf Q=\dfrac34, \ R=\dfrac32, \ S=\dfrac94[/tex]
Sorry forgot to post pictures of the question on last post (here there are)
For question 4 and 5 You have to find what the equation would look like on a graph. brainly wouldn't let me post all the answer options for those questions sorry!
Answer:
See below for answers and explanations
Step-by-step explanation:
Problem 1
[tex]x=-3+2cos\theta,\:y=5+2sin\theta\\\\x+3=2cos\theta,\: y-5=2sin\theta\\\\(x+3)^2=4cos^2\theta,\: (y-5)^2=4sin^2\theta\\\\(x+3)^2+(y-5)^2=4cos^2\theta+4sin^2\theta\\\\(x+3)^2+(y-5)^2=4(cos^2\theta+sin^2\theta)\\\\(x+3)^2+(y-5)^2=4(1)\\\\(x+3)^2+(y-5)^2=4[/tex]
Thus, the first option is correct. Trying all the other options will not get you the desired rectangular equation.
Problem 2
[tex]x=3-6cos\theta,\: y=-2+3sin\theta\\\\x-3=-6cos\theta,\: y+2=3sin\theta\\\\\frac{x-3}{-6}=cos\theta,\: \frac{y+2}{3}=sin\theta\\ \\ \frac{(x-3)^2}{36}=cos^2\theta,\: \frac{(y+2)^2}{9}=sin^2\theta\\ \\ \frac{(x-3)^2}{36}+\frac{(y+2)^2}{9}=cos^2\theta+sin^2\theta\\\\ \frac{(x-3)^2}{36}+\frac{(y+2)^2}{9}=1[/tex]
Therefore, the first option is correct. This equation is in the form of an ellipse with a horizontal major axis length of 12 (half is 6) and a vertical minor axis length of 6 (half is 3), with its center at (3,-2).
Problem 3
Not sure which equation needs to be used for this problem
Problem 4
[tex]x=-7cos\theta ,\:y=5sin\theta\\\\-\frac{x}{7}=cos\theta,\: \frac{y}{5}=sin\theta\\ \\ \frac{x^2}{49}=cos^2\theta,\: \frac{y^2}{25}=sin^2\theta\\ \\\frac{x^2}{49}+\frac{y^2}{25}=cos^2\theta+sin^2\theta\\ \\ \frac{x^2}{49}+\frac{y^2}{25}=1[/tex]
This equation is in the form of an ellipse with a horizontal major axis length of 14 (half is 7) and a vertical minor axis length of 10 (half is 5). See attached graph.
Problem 5
Eliminate the parameter:
[tex]x=-t^2-2,\:y=-t^3+4t\\\\x+2=-t^2\\\\-x-2=t^2\\\\\pm\sqrt{-x-2}=t\\\\y=-t^3+4t\\\\y=-(\pm\sqrt{-x-2})^3+4(\pm\sqrt{-x-2})[/tex]
Attached below is the graph of the curve, which corresponds with the first option.
