We can see a pattern:
Days >> Pennies1 >> 1= 2^02 >> 2= 2^13 >> 4 = 2^24 >> 8 = 2^3...n >> 2^(n-1)So
January 5 fall on n = 5, therefore 2^4 = 16 penniesJanuary 10 falls on n = 10, therefore 2^9 = 512 penniesJanuary 31 falls on n = 31, therefore 2^30 = 1073741824 penniesWhich of the following ratios is closest to the golden ratio? a. 5/3
b. 7/5
c. 10/8
d. 14/11
Answer:
A 5/3
Step-by-step explanation:
The fraction closest to the golden ratio is a. 5/3.
What is a golden ratio?The golden ratio is a ratio between two numbers that approximate 1.618.
It is sometimes referred to as the golden number, the golden proportion, or the divine proportion.
It is closely related to the Fibonacci sequence, a set of numbers where each number is added to the previous one and is typically written as the Greek letter Ф.
From the given options,
5/3 = 1.66.
7/5 = 1.4.
10/8 = 1.25.
14/11 = 1.27.
So, the closest ratio is 1.6 which is 5/3.

Find the x and y intercepts of the line
Answer:
The x-intercept of the line is [tex]-\frac{3}{7}[/tex]
The y-intercept of the line is 3
Step-by-step explanation:
If the equation of a line is y = m x + b, then
The x- intercept is the value x at y = 0, (that means, the line intersect the x-axis at point (x, 0)The y-intercept is the value of y at x = 0, (that means, the line intersect the y-axis at point (0, y)Let us use these facts to solve the question
∵ y = 7x + 3
→ Substitute y by 0 to find the x-intercept
∵ y = 0
∴ 0 = 7x + 3
→ Subtract 3 from both sides
∵ 0 - 3 = 7x + 3 - 3
∴ -3 = 7x
→ Divide both sides by 7 to find x
∵ [tex]-\frac{3}{7}[/tex] = [tex]\frac{7x}{7}[/tex]
∴ [tex]-\frac{3}{7}[/tex] = x
∴ The x-intercept of the line is [tex]-\frac{3}{7}[/tex]
∵ y = 7x + 3
→ Substitute x by 0 to find the y-intercept
∵ x = 0
∴ y = 7(0) + 3
∴ y = 0 + 3
∴ y = 3
∴ The y-intercept of the line is 3

Piper used 1/5 meter of ribbon to create a border around a triangle if each side of the triangle is the same length how much ribbon did Piper use for each side?
Answer:
[tex]\frac{1}{15}[/tex]
Step-by-step explanation:
as said in the question that the triangle has three equal sides. i.e. this is an equilateral triangle. So,
let us consider one side of the triangle to be x . and 3x( x+x+x) should be equal to 1/5
[tex]x+x+x = \frac{1}{5}\\3x=\frac{1}{5}\\x = \frac{1}{5} / 3\\x = \frac{1}{5} * \frac{1}{3}\\x = \frac{1}{15}[/tex]
Slope of (3, -9) (3, 18)
Answer:
Undefined.
Step-by-step explanation:
To calculate the slope between two points on a graph, we use [tex]\frac{y2-y1}{x2-x1}[/tex].
Once we substitute in the provided points, this becomes [tex]\frac{18-(-9)}{3-3}[/tex].
Simplify to [tex]\frac{27}{0}[/tex].
This does not give us a number and instead results in an undefined slope, aka a vertical line.

What percent of 438 is 106? Let p= the percent.
Let's create a simple proportion.
p = Percent
p/100 = 106/438
Now, cross multiply.
438p = 10,600
Divide both sides by 438 to isolate p.
p ≈ 24.200913242
Therefore, 106 is approximately 24.201 percent of 438.
106 is 24% of 438.
What is percentage?A relative value indicating hundredth parts of any quantity.
Given that, a number 438
Let p be the percent,
p% of 438 = 106
p = 106*100/438
p = 24%
Hence, 106 is 24% of 438.

A researcher conducts a hypothesis test using a sample of n = 40 from an unknown population. What is the df value for the t statistic?
a. 38
b. 39
c. 40
d. 41
Answer:
Correct option: b 39.
Step-by-step explanation:
A one-sample (or one mean) t-test is applied to test whether the population-parameter is significantly different from some hypothetical value.
The degrees of freedom of the t-test is:
df = n - 1
It is provided that the sample size is, n = 40.
Compute the degrees of freedom as follows:
df = n - 1
= 40 - 1
= 39
Thus, the correct option is b.

The graph the formula representing the compound interest will be exponential function.
What is graph?
In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".
Given is the equation representing compound interest.
The equation representing the compound interest is -
C = P( 1 + r/n )ⁿˣ
Where -
[P] is principle amount.
[r] is rate.
[x] is time.
The exponential function is eˣ, where [x] is a variable. Similarly, we can graph the formula representing the compound interest as shown in the figure attached. The graph will be exponential in nature.
Therefore, the graph the formula representing the compound interest will be exponential function.
