A school club uses a telephone chain to inform members of changes in plans. The club president calls 2 members, each of whom calls 2 members, and so on. The process must be repeated 5 times. How many members are in the club?
Answer:
63 members
Step-by-step explanation:
Since each person calls 2 persons each, there is an exponential increase of 2 for each level. Since it starts with the president as 1 person, and increases exponentially by 2 for each level of phone call, we have a geometric progression of first term, a = 1 and common ratio r = 2. Since the process of phone calls must be repeated 5 times, our last term is 2⁵. So, our geometric progression is 2⁰ + 2¹ + 2² + 2³ + 2⁴ + 2⁵ = 1 + 2¹ + 2² + 2³ + 2⁴ + 2⁵
We now sum the geometric progression
The sum of a geometric progression with r > 1 is
S = a(rⁿ - 1)/(r - 1)
substituting r = 2, a = 1 and n = 6 since we have 6 terms, we have
S = 1(2⁶ - 1)/(2 - 1)
= (64 - 1)/1
= 63
So, we have 63 members in the club.
We could have also found this by summing up individually the terms in the series. We have 1 + 2¹ + 2² + 2³ + 2⁴ + 2⁵ = 1 + 2 + 4 + 8 + 16 + 32 = 63

Find the area. Simplify your answer.
Answer:
area = x² - 7x
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 2x and h = x - 7 , thus
A = [tex]\frac{1}{2}[/tex] × 2x(x - 7) = x(x - 7) = x² - 7x
Answer:
a=x^2-7x
Step-by-step explanation:
a=1/2bh
a=1/2(x-7)(2x)
a=1/2(2x^2-14x)
a=x^2-7x

Determine which of the lines are parallel and which of the lines are perpendicular. ROW1 Parallel Perpendicular DRAG & DROP THE ANSWER Lines c and d Lines a and c Lines a and b Lines b and c
Answer:
a & b are parallel to each other. c and d are also parallel to each other
a & c are perpendicular; b and c are also perpendicular
Explanation: Perpendiculars are when two lines meet to make a 90 degrees right angle. Parallel are two lines that never meet at all. Instead, they have the same distance apart across . Think about it as two different streets.

Adam gets a bonus of 30% of £80 Katy gets a bonus of £28
what is the difference between the bonus Adam gets and the bonus Katy gets?
Answer:
£4
Step-by-step explanation:
Adam: 30% of £80
Katy: £28
First, let's fund Adam's bonus. We know that 30% is equal to 0.3. Then, we can multiply £80 by 0.3. This results in £24.
We also know that Katy made £28. Now we need to find the difference.
The difference between Adam and Katy is £4.

A line with slope -3 passes through the points (5,2) and (9,y). Find y.
plz help!
Answer:
y is 10
Step-by-step explanation:
first take your imformation and put it into the y intercept from.
Which is y=mx+b
so take the cordinates (5,2) and put it into the y-intercept form.
the 5 is x and the 2 is the y, so
2=m*5+b
Then take the slope of -3 and put it in the y-intecept from
2=-3*5+b
then solve for b
2=-3*5+b
2=-15+b
+15 on both sides
17=b
now you know the equation of the line is
y=-3x+17
now plug in your x to find the y of that cordinate
on the line.
y=-3*9+17
solve
y=-3*9+17
y=-27+17
y=10

Answer:
Step-by-step explanation:
For the first part:
[tex](x-7)^2=36\\\sqrt{(x-7)^2}=\sqrt{36}\\[/tex]
(x-7)=±6
so lets take +6 first
x-7=6
x=6+7
x=13
now lets take -6
x-7=-6
x=-6+7
x=1
For the second part:
[tex](x-1)^2=50\\\sqrt{(x-1)^2}=\sqrt{50}\\[/tex]
x-1=±7.07
so lets take +7.07
x-1=7.07
x=7.07+1
x=8.07
now lets take -7.07
x-1=-7.07
x=-7.07+1

What value of n makes
(5^n)(5^2)=5^16 true?
Answer:
14
Step-by-step explanation:
By following the exponent rule, when multiplying two numbers of the same term with exponents, you simply add them together.
Therefore, to make (5^n)(5^2)=5^16 true, n must equal 14 since:
14 + 2 = 16
Answer:
n = 14
Step-by-step explanation:
Recall the rule:
[tex] a^m \times a^n = a^{m + n} [/tex]
[tex] (5^n)(5^2) = 5^{16} [/tex]
[tex] (5^n)(5^2) = 5^{n + 2} = 5^{16} [/tex]
[tex] n + 2 = 16 [/tex]
[tex] n = 14 [/tex]

Answer:
x≥12, Michael must grow for 12 more months (a year) before he can ride a roller coaster.
Step-by-step explanation:
The inequality to represent how tall you must be to go on a roller coaster is
x≥48 because you must be a minimum of 48 inches tall, 'x' represents how tall you must be
If Michael is already 42 inches tall, that is his base point but you need to know how many more months he will need to grow for.
1/2x represents the amount of months Michael needs to grow, x is the unknown variable we need to solve for which represents the months he needs to grow, 1/2 is how many inches he grows in 1 month
42+1/2x≥ 48
subtract 42 from each side) 1/2x≥6
multiply both sides by 2) x≥12

Is the trend line linear? If so, write a linear equation that represents the trend line. Show your work.
A graph showing the fat and calories content has increased in the number of calories with the increasing number of fat.
A linear trend is the best fit straight line that is showing a positive relationship as it's going upwards. As the plotted residues represent a line that is almost straight and these data points resemble a line. This trend shows an increase in the data correlation. For example, the increased in distance will lead to an increase in time and this can be positively correlated within the graph. The equation of y = MX + b and y = 10x + 0 for a and b.Thus the graph shows a linear trend and in increasing order.

Answer:
The equation is "Y = 56.36*X + 56.47"
Step-by-step explanation:
The form of the equation is y=mx+b, m = slope and b = intercept.
You have to find the slope of the trend line or you can use the plot points, but identifying the slope in the trend line is much easier.
It seems there are two points that are outliers and need no paying attention to, this is because outliers can make predictions unreliable and also make the trend line unreliable overall as well.
