The graph shows the function of f(x)=(3.5)^x
Which graph represents the function g(x)=(3.5)^x-1?
Answer:
The graph of the function is the last graph.
Step-by-step explanation:
To know which graph represents the function [tex]g(x)=3.5^{x-1}[/tex] you should give values to x and compare it with the values on the graphs, as follows:
When x=-3
[tex]g(-3)=3.5^{-3-1}[/tex]
[tex]g(-3)=3.5^{-4}[/tex]
[tex]g(-3)=0.007[/tex]
So, the first point is (-3, 0.007)
When x=-2
[tex]g(-2)=3.5^{-2-1}[/tex]
[tex]g(-2)=3.5^{-3}[/tex]
[tex]g(-2)=0.02[/tex]
So, the second point is (-2, 0.02)
When x=-1
[tex]g(-1)=3.5^{-1-1}[/tex]
[tex]g(-1)=3.5^{-2}[/tex]
[tex]g(-1)=0.08[/tex]
So, the third point is (-1, 0.08)
When x=0
[tex]g(0)=3.5^{0-1}[/tex]
[tex]g(0)=3.5^{-1}[/tex]
[tex]g(0)=0.29[/tex]
So, the fourth point is (0, 0.29)
When x=1
[tex]g(1)=3.5^{1-1}[/tex]
[tex]g(1)=3.5^{0}[/tex]
[tex]g(1)=1[/tex]
So, the fifth point is (1, 1)
When x=2
[tex]g(2)=3.5^{2-1}[/tex]
[tex]g(2)=3.5^{1}[/tex]
[tex]g(2)=3.5[/tex]
So, the fourth point is (2, 3.5)
If you compares all the points, the graph of the function is the last graph.

what is the explicit formula and recursive formula of the numbers 4,7,10,13,16...i don't even know how to start this problem. i just need a bit of help or the answer because I'm running out of time.
An arithmetic sequence is a sequence with a constant
increase or decrease also known as the constant difference
In the sequence 10, 40, 70, 100, ….
The constant difference between the terms is 30
A recursive formula for a sequence would be:
a1= first term in the sequence
an = term you are trying to find
an-1 = previous term in the sequence
d = constant difference
Explicit Formulas:
A formula that allows you to find the nth term of the sequence by substituting known values in the expression.
Formula : an = a1 + d( n - 1)
a1= first term in the sequence
an = current term in the sequence
d = constant difference
n = term number
Solution:
Write the explicit formula of the sequence 4, 7, 10, 13, 16 ….
Formula for explicit term:
an = ___ + ___( n - 1)
Simplify: an = ___ + ___n
In the sequence 4, 7, 10, 13, ….
To find the 11th term explicitly, I plug in the into the formula I just made:
an = 1 + 3n
a11 = 1 + 3(11)
a11 = 34
Find the 15th term of the sequence using the formula: an = 1 + 3n
Write the recursive formula of the sequence 4, 7, 10, 13, ….
Recursive formula:
a1 =
an = a n - 1
In the sequence 4, 7, 10, 13, 16 ….
To find the 5th term recursively, I plug it into the formula I just made:
an = an-1 + 3
a5 = a5-1 + 3 in words: 5th term equals the 4th term plus 3
a5 = 13 + 3
a5 = 16

The manager of a sawmill wants to find out what percentage of the boards that the mill produced are defective. Which sampling methods are likely to be biased? Select each correct answer.
A.Every 40th board produced over the course of 1 week is selected and examined.
B. On 1 day, an hour after the sawmill begins production, 30 boards in a row are selected and examined.
C. The manager selects 20 boards at random each day for 5 days and examines them.
D. The manager sends an email to 20 customers who buy lumber from the mill, asking each how many of the boards they bought the past week were defective. Results from the first 5 customers to respond are tallied.
Sampling is the choosing of a group of individuals from within a statistical population to estimate attributes of the entire population. Options C & D are right.
What is the sampling method ?Sampling is the choosing of a group of individuals from within a statistical population to estimate attributes of the entire population in statistics, quality assurance, and survey methods.
The following options are right;
C. The manager selects 20 boards at random each day for 5 days and examines them.
Reason;
This method, which involves sampling 30 boards in a row an hour after manufacturing begins, does not yield a significant sample size.
Furthermore, if a component of the equipment fails later in the day, the statistics will be deceptive. Similarly, statistics will be deceptive if the gear is only defective until it "warms up."
D. The manager sends an email to 20 customers who buy lumber from the mill, asking each how many of the boards they bought the past week was defective. Results from the first 5 customers to respond are tallied.
Reason;
These technique, a voluntary survey, is likely to elicit replies solely from those who have strong feelings about their product.
Hence Options C & D are right.

https://brainly.com/question/15125943
Methods B and D are biased for determining defective boards, while methods A and C minimize bias. Random sampling across different times and responses reduces bias in data.
The goal is to determine which sampling methods are likely to be biased when finding the percentage of defective boards produced by a sawmill.
A. Every 40th board produced over the course of 1 week is selected and examined. Bias: This method minimizes bias as it spreads out samples over time.B. On 1 day, an hour after the sawmill begins production, 30 boards in a row are selected and examined. Bias: This is likely biased as it does not account for variations in production quality at different times of the day.C. The manager selects 20 boards at random each day for 5 days and examines them. Unbiased: This method reduces bias by randomly sampling boards each day.D. The manager sends an email to 20 customers who buy lumber from the mill, asking each how many of the boards they bought the past week were defective. Results from the first 5 customers to respond are tallied. Bias: This method is extremely biased as it relies on customer responses, which can be non-representative and influenced by response rate.In summary, method B and method D are likely to introduce bias in sampling. Methods A and C are designed to minimize bias and provide a more accurate representation of defective boards.

Determine if the properties define a Ray or a line segment
A ray in geometric optics represents the path of light as a straight line originating from a point, while a line segment is a part of a line with two endpoints and a measurable length. The properties mentioned can be used to determine if they define a ray or a line segment.
Explanation:A ray in geometric optics is a straight line that originates at some point. In the context of light, a ray represents the path of light as it travels. When light encounters objects or changes media, it may change direction but it continues to travel in a straight line or as a ray. We can think of a ray of light as a straight line or a laser ray.
A line segment, on the other hand, is a part of a line with two endpoints. It has a definite length and can be measured. In the context of light, a line segment would indicate a finite path of light.
Given the properties mentioned, we can determine if they define a ray or a line segment. If the properties describe a straight line with no defined endpoints, it is a ray. If the properties suggest a line with two endpoints and a measurable length, it is a line segment.

Solving Systems of Equations by Elimination
3) 7x + 3y= 22 4y= 20
4) -2x + y= 10 4x - y= -14
Answer:
3) [tex]x=1\\ y=5[/tex]
4) [tex]x=-2\\ y=6[/tex]
Step-by-step explanation:
3) For this system of equation you already has one variable in the second equation. Therefore, you only need to solve for [tex]y[/tex] in the second one and substitute its value into the first equation to calculate [tex]x[/tex]:
[tex]\left \{ {{7x + 3y= 22} \atop {4y=20}} \right. \\[/tex]
[tex]y=\frac{20}{4} \\ y=5[/tex]
[tex]7x + 3(5)= 22\\ 7x=7\\x=1[/tex]
4) You must add both equations to cancel the variable [tex]y[/tex] and solve for [tex]x[/tex]. Then, susbstiute the value of this variable into one of the original equations to calculate [tex]y[/tex]:
[tex]\left \{ {{-2x+y=10} \atop {4x-y=-14}} \right.[/tex]

A jar lid has a diameter of 42 millimeters. What is the circumference of the lid? Use 22/7 for π.
A. 924 mm
B. 114 mm
C. 66 mm
D. 132 mm
Final answer:
The circumference of the lid is approximately 132 millimeters, Thus, option D is correct.
Explanation:
To find the circumference [tex](\( C \))[/tex] of the lid, we use the formula for the circumference of a circle:
[tex]\[ C = \pi \times d \][/tex]
Where [tex]\( d \)[/tex] is the diameter of the circle.
Given that the diameter (\( d \)) of the lid is 42 millimeters and using the value of [tex]\( \pi \)[/tex] as [tex]\( \frac{22}{7} \)[/tex], we can calculate the circumference as follows:
[tex]\[ C = \frac{22}{7} \times 42 \][/tex]
[tex]\[ C = \frac{22 \times 42}{7} \][/tex]
[tex]\[ C = \frac{924}{7} \][/tex]
[tex]\[ C \approx 132 \, \text{mm} \][/tex]
Therefore, the circumference of the lid is approximately 132 millimeters, which corresponds to option D.
