Which one of these is NOT a step used when constructing an inscribed hexagon using technology? (5 points)
Connect the point with a line through the center of the circle.
Mark the points of intersection between the two circles.
Create another circle with the same radius as the original.
Create a circle using the center with given point tool.
Answer:
the answer is A, connect the point with a line through the center of the circle
Step-by-step explanation:
Create another circle with the same radius as the original. Technology doesn't require this step. Lines, intersections, and circles with the centre and provided point are the steps.
When building an inscribed hexagon with technology, this step is skipped: Make a circle with the same radius as the first.
The following steps are used to build an inscribed hexagon: Create a circle using the centre with a point tool to illustrate the circumscribed circle.
Connect the point with a line through the circle's centre to create its diameter.
Mark the intersections of the two circles (the hexagon's vertices).
Form the inscribed hexagon by connecting the marked spots.
The typical method for building an inscribed hexagon does not involve making a circle with the same radius.

Identify the graph of ƒ(x) = x2 + 6x – 7 from the choices below.
f(x) = x^2 + 6x - 7
y = x^2 + 6x - 7

A group of 55 football players was polled about which synthetic grass they like to play on, Chemgrass or Chemstrand. The data from the survey is shown in the Venn diagram. Use the Venn diagram to find the missing values in the frequency table. A circle labeled chemstrand 15 overlaps a circle labeled chemgrass 17. Overlap is labeled 13. 4-column table with 3 rows. First column has no label with entries likes chemgrass, does not like chemgass, total. Second column is likes chemstrand with entries x, z, 28. Third column is does not like chemstrand with entries y, 10, 27. Fourth column is total with entries 30, 25, 55. What are the values of x, y, and z? x = 17, y = 15, and z = 13 x = 13, y = 15, and z = 17 x = 15, y = 13, and z = 17 x = 13, y = 17, and z = 15
Answer:
From the Venn diagram: 15 players like Chemstrand, 17 players like Chemgrass, 13 players like both Chemstrand and Chemgrass while 10 players like neither Chemstrand nor Chemgrass.
The missing values in the frequency table are x - representing the number of players that like both Chemstrand and Chemgrass, y - representing the number of players that like Chemgrass but do not like Chemstrand and z - representing the number of players likes Chemstrand but do not like Chemgrass.
The number of players that like both Chemstrand and Chemgrass is 13. The number of players that like Chemgrass but do not like Chemstrand is 17. The number of players likes Chemstrand but do not like Chemgrass is 15.
Therefore, x = 13, y = 17 and z = 15
The values of x, y, and z from the Venn diagram are:
x = 13, y = 15, and z = 17.
What is a Venn diagram?A Venn diagram is an overlapping circle to describe the logical relationships between two or more sets of items.
We have,
From the Venn diagram, we can see that:
The total number of players who like Chemgrass is 17 + 13 = 30.
The total number of players who like Chemstrand is 13 + 15 = 28.
The total number of players who do not like Chemgrass is 10 + 13 = 23.
The total number of players who do not like Chemstrand is 10 + 17 = 27.
The total number of players is 55.
Now,
We can fill in the missing values in the frequency table using the information above:
The value of x (the number of players who like both Chemgrass and Chemstrand) is the overlap between the two circles, which is 13.
The value of y (the number of players who like Chemstrand but not Chemgrass) is the number of players who like Chemstrand (28) minus the number of players who like both (13), which is 15.
The value of z (the number of players who like Chemgrass but not Chemstrand) is the number of players who like Chemgrass (30) minus the number of players who like both (13), which is 17.
Therefore,
The values of x, y, and z are x = 13, y = 15, and z = 17.

Answer:
16 seconds
Step-by-step explanation:
You basically have to do all numbers times 2
The required time the electric clock would take to sound 6 times is 16 seconds at 6:00.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
It takes 8 seconds for an electric clock to sound 3 times, so it takes,

Max invests some money in a savings bond.
The savings bond pays interest at a rate of 2% per year.
At the end of the first year, his savings bond is worth £5763
(b) How much money did Max invest in the savings bond?
Answer:
£5650
Step-by-step explanation:
The money max invested in the saving bond = x
After one year the intrest will be 2% of x
Amount = £5763
Amount = Principcal + Interest
= £5763 = x + 2% multiplied x
£5763 = x + 2x/100
= 50x/50 + x/50 = 5763
= 51x/50 = £5763
51x = 5763x50
51x = 288, 150
x = 288,150/51
x = 5650
So the money max invested = £5650

The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 185 grams of a radioactive isotope, how much will be left after 6 half-lives?
Use the calculator provided and round your answer to the nearest gram.
Answer:
Approximately 3 grams left.
Step-by-step explanation:
We will utilize the standard form of an exponential function, given by:
[tex]f(t)=a(r)^t[/tex]
In the case of half-life, our rate r will be 1/2. This is because 1/2 or 50% will be left after t half-lives.
Our initial amount a is 185 grams.
So, by substitution, we have:
[tex]\displaystyle f(t)=185\big(\frac{1}{2}\big)^t[/tex]
Where f(t) denotes the amount of grams left after t half-lives.
We want to find the amount left after 6 half-lives. Therefore, t = 6. Then using our function, we acquire:
[tex]\displaystyle f(6)=185\big(\frac{1}{2}\big)^6[/tex]
Evaluate:
[tex]\displaystyle f(6)=185\big(\frac{1}{64}\big)\approx2.89\approx 3[/tex]
So, after six half-lives, there will be approximately 3 grams left.

1 x 3250 = 3250
2 x 1625 = 3250
5 x 650 = 3250
10 x 325 = 3250
13 x 250 = 3250
25 x 130 = 3250
26 x 125 = 3250
