The second graph does not represent the y as a function of x.
What is the function?
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
The x value of a point where a vertical line intersects a function represents the input for that output y value.
If we can draw any horizontal line that intersects a graph more than once, then the graph does not represent a function because that y value has more than one input.
If we draw a line parallel to the y-axis it cuts the graph in more than one point.
So, that does not represent a function.
Here, we have given four graphs
Among this, the second graph intersects the x-axis two times,
Hence, the second graph does not represent y as a function of x.

The solution to the given exponential equation is 0.791.
What is a logarithm?
The logarithm is the inverse function of exponentiation in mathematics. That is, the exponent to which b must be raised to produce x is the logarithm of a number x to the base b.
Given exponential function is
5x⁻² = 8
Divide both sides by 5:
x⁻² = 8/5
x⁻² = 1.6
Taking logarithm of base x:
[tex]log_x(x^{-2})=log_x1.6[/tex]
-2 [tex]=log_x(1.6)[/tex]
Now applying the logarithm of change of base formula:
-2 = log 1.6/log x
Divide both sides by -2:
1 = log 1.6/( -2log x)
Multiply both sides by log x:
log x = log 1.6/-2
log x = -0.1021
Now applying the formula [tex]log_xa = b[/tex] implies [tex]a = x^b[/tex]:

Given that a is an odd multiple of 1183, find the greatest common divisor of 2a^2+29a+65 and a+13
Answers
The solution is 26, since gcd (26, a + 13) = 26 when a = 1183k, and k = 1,3,5,7,9...
Let d = [tex](2a^{2} +29a + 65, a+ 13)[/tex]
Now, we can split [tex]2a^{2} + 29a + 65[/tex] in the following way, so that it becomes easier to factorise.
[tex]2a^{2} + 29a + 65 = (2a^{2} + 29a + 39) + 26[/tex]
From this, we can quantify and notice that -13 is one root of this equation, while the other root is -3/2.
Therefore, [tex]2a^{2} + 29a + 39 = (a+13)(2a+3)+26[/tex]
Thus, [tex]d = ((a+13)(2a+3)+26, a+ 13)[/tex]
The greatest common divisor (GCD) of two or more numbers is the greatest common factor number that divides them, exactly. It is also called the highest common factor (HCF).
Now, we can use Euclid's Algorithm.
[tex]= gcd (2a^{2} + 29a + 65, a + 13)\\= gcd (2a^{2} + 29a + 65 - 2a(a+13), a+13)\\= gcd (3a + 65, a + 13)\\= gcd (3a + 65 - 3a(a+13), a+13)\\= gcd (26, a + 13)[/tex]
This is necessarily 1, 2, 13, or 26, which we can see by just looking at the first term. By factoring 1183 and considering that [tex]a[/tex] is an odd multiple, then we should be able to conclude the answer.
Hence, the conclusion is that the solution is 26, since gcd (26, a + 13) = 26 when a = 1183k, and k = 1,3,5,7,9...

Answers
9,900 codes that are available for reckha.
There are a total of 10,000 possible three-digit codes when each digit is in the set {0,1,2,3,4,5,6,7,8,9}. Since each digit can take 10 different values, we can use the formula 10^3 = 1000 to calculate the total number of codes.
However, since reckha cannot choose a code that is the same as yours or one that is the same as yours except for switching the positions of two digits, we have to subtract these possibilities from the total. We can calculate the number of codes forbidden by subtracting the number of codes with the same digits in all three positions (10) and the number of codes with the same digits but different positions (90) from the total. This leaves us with 10,000 - (10 + 90) = 9,900 codes that are available for reckha.

Answers
The approximate percentage of daily phone calls numbering between 46 and 82 is 95%.
The Empirical Rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations, and approximately 99.7% falls within three standard deviations.
In this case, the mean is 64 and the standard deviation is 9. Therefore, approximately 68% of the daily phone calls answered by each receptionist fall between 64 - 9 = 55 and 64 + 9 = 73.
Additionally, approximately 95% of the data falls between 64-18 = 46 and 64 + 18 = 82.

how many integers $n$ less than $1000$ can be written as the sum of $j$ consecutive positive odd integers from exactly 5 values of $j\ge 1$?
Answers
The number of integers N less than 1000 that can be written as the sum of j consecutive positive odd integers from exactly 5 values of j ≥ 1 is 15.
Arithmetic sequence is a sequence of numbers/terms that has a fixed pattern, based on the operation of subtraction or addition. Thus, each sequence of numbers will have a common difference.
Formula: aₙ = a₁ + (a - 1)d,
where aₙ is the nᵗʰ term and a₁ is the first term in the sequence, and d is the common difference between terms
Sum of n terms = n (a₁ + aₙ) / 2
We want to know the number of integers N less than 1000 that can be written as the sum of j consecutive positive odd integers from exactly 5 values of j ≥ 1
First, we determine:
- the first odd integer in the list: 2n + 1, where n ≥ 1
- the last odd integer in the list: 2n + 1 + 2(j - 1) = 2(n + j) - 1
These odd integers form a sequence with the following sum:
N = n (a₁ + aₙ) / 2
= j (2n + 1 + 2(n + j) - 1) / 2
= j (2n + 1 + 2n + 2j - 1) / 2
= j (4n + 2j) / 2
= j (2n + j)
We also know that there are exactly 5 values of j that satisfy the equation, there must be either 9 or 10 factors of N.
This means N = p₁².p₂² or N = p₁.p₂⁴
If N is odd, then j is also odd, which means that 2n+j is also odd. It is valid for all odd j. Given the boundary of 1000, the possibilities of odd N are (3².5²), (3².7²), (3⁴.5), (3⁴.7), and (3⁴.11) ---> 5 possibilities
If N is even, then j is also even. If we substitute j = 2k into the N, we get:
N = j (2n + j)
= 2k (2n + k)
= 4k (n + k)
N/4 = k (n + k)
This formula implies that the new upper bound is 250. So the possibilities of even N are (2².3²), (2².5²), (2².7²), (3².5²), (2⁴.3), (2⁴.5), (2⁴.7), (2⁴.11), (2⁴.13), and (3⁴.2) ---> 10 possibilities
Thus, the total number of integer N is 5 + 10 = 15

The first 60 miles of the journey would be represented by a straight line with a slope of 60/1=60, since the car is traveling at a constant speed of 60 mph.
The point where the first 60 miles ends would be (1,60) which is the time of one hour from London, the distance of 60 miles from London.
After the 30-minute break at the motorway services, the car would continue its journey at a constant speed of 70 mph. This part of the journey would be represented by a straight line with a slope of 70/1=70.
The point where the whole journey ends would be (4,200) which is the time of 4 hours from London, the distance of 200 miles from London.

the perimeter of an isosceles triangle (2 equal sides) pqr is 9 cm. the length of side p is 4 cm and the lengths of q and r are equal
Answers
The lengths of q and r are 2.5 , 2.5 respectively if the perimeter of an isosceles triangle pqr is 9 cm.
What is a triangle ?
triangle can be defined in which it consists of three sides , three angles and the sum of three angles is always 180 degrees.
Given ,
The perimeter of an isosceles triangle (2 equal sides) pqr is 9 cm.
the length of side p is 4 cm
Let the lengths of q and r are x and y respectively.
The perimeter of an isosceles triangle = (p+2q)
So,
p+2q = 9
4+2q = 9
2q = 9-4
2q = 5
q = 5/2
q = 2.5 cm
Hence , the lengths of q and r are 2.5 , 2.5 cm respectively .

Suppose you know that the amount of time it takes your friend Susan to get from her residence to class averages 50 minutes, with a standard deviation of 5 minutes. What proportion of Susan's trips to class would take less than 40 minutes? What proportion of Susan's trips to class would take more than 50 minutes or less than 40 minutes?
Answers
Answer:
To solve this problem, we will use the following steps:
Step 1: We know that the amount of time it takes Susan to get from her residence to class averages 50 minutes, with a standard deviation of 5 minutes. So we can use this information to calculate the proportion of Susan's trips to class that would take less than 40 minutes.
Step 2: To calculate the proportion of Susan's trips to class that would take less than 40 minutes, we need to find the z-score for the value of 40 minutes. We can use the following formula to find the z-score:
z = (x - μ) / σ
Where x is the value we are interested in (40 minutes), μ is the mean (50 minutes), and σ is the standard deviation (5 minutes).
z = (40 - 50) / 5 = -2
Step 3: We can use a standard normal table or a calculator to find the proportion of Susan's trips to class that would take less than 40 minutes.
The proportion of Susan's trips to class that would take less than 40 minutes is 0.0228 or 2.28%.
Step 4: To calculate the proportion of Susan's trips to class that would take more than 50 minutes or less than 40 minutes, we need to find the proportion of Susan's trips to class that would take more than 50 minutes and add it to the proportion of Susan's trips to class that would take less than 40 minutes.
Step 5: To find the proportion of Susan's trips to class that would take more than 50 minutes, we need to find the z-score for the value of 50 minutes.
z = (50 - 50) / 5 = 0
Using a standard normal table or a calculator, the proportion of Susan's trips to class that would take more than 50 minutes is 0.5 or 50%.
Step 6: Finally, we can add the proportion of Susan's trips to class that would take more than 50 minutes and the proportion of Susan's trips to class that would take less than 40 minutes to find the proportion of Susan's trips to class that would take more than 50 minutes or less than 40 minutes.
0.50 + 0.0228 = 0.5228 or 52.28%
Final Answer: The proportion of Susan's trips to class that would take more than 50 minutes or less than 40 minutes is 0.5228 or 52.28%.
