5. The sum of two numbers is 56. The difference of the two numbers is 9. What is theproduct of the two numbers?What are you being asked to find?What are you given?Define your variables.?Create & solve a system.Explain your solution.
Answers
Define your variable:
Let x and y be two numbers.
What are you given?
We know that,
\(\begin{gathered} x+y=56 \\ \text{and} \\ x-y=9 \end{gathered}\)Create and solve a system.
The system is
\(\begin{gathered} x+y=56 \\ x-y=9 \end{gathered}\)Explain your solution.
We can solve this systemn by elimination method. If we add both equation, we obtain
\(x+x=56+9\)because y-y=0. Then, we have
\(\begin{gathered} 2x=65 \\ x=\frac{65}{2} \\ x=32.5 \end{gathered}\)Now, we must substitute this value into the first equation. It yields,
\(\begin{gathered} 32.5+y=56 \\ y=56-32.5 \\ y=23.5 \end{gathered}\)Therefore, the answer is x=32.5 and y=23.5
5. If you were told that a specific tire could roll 200 yards in 27.28 revolutions, what is the radius of the tire?
Answers
The number of revolutions = Total distance divided by its circumference
The radius of the tire is 1.167 yards.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of
2πr.
The area of a circle is given as πr².
We have,
The number of revolutions = Total distance divided by its circumference
Total distance = 200 yards
Revolutions = 27.28
A tire is in the form of a circle.
So,
The circumference of the tire.
= 2πr
Now,
27.28 = 200 yards / 2πr
2πr = 200 yards / 27.28
r = 200/(27.28 x 2 x 3.14)
r = 200 / 171.32
r = 1.167 yards.
The radius of the tire is 1.167 yards.

Find the second differences
Answers
The second difference of the given number table is: Option A: -2
How to find the second differences?The second difference method can be used to determine a quadratic model. In order for us to calculate the second difference, we will select 3 consecutive y-values, and then subtract the first y-value from the second and the second y-value form the third. Then we will find the difference of these two resulting values. That difference is what we refer to as the second difference.
Thus, Applying the second difference concept to our problem, we have:
First difference:
-4 - (-9) = 5
-1 - (-4) = 3
Thus, second difference is:
3 - 5 = -2

What is the domain of f(x)=(1/2)^x
Answers
The required domain of the exponential function \(f(x) = (1/2)^x\) is all real numbers i.e. x = (-∞ , ∞)
Given that,
\(f(x) = (1/2)^x\),
The domain for the above-given function is to be determined.
The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable that exists in the range of the function.
In the question,
The equation \(f(x) = (1/2)^x\) is an exponential function with the independent variable x on the exponent of base 1/2.
Since this function is defined in any value on the x-axis, so the domain is all real numbers.i.e. x = (-∞, ∞)
Thus, the required domain of the exponential function \(f(x) = (1/2)^x\) is all real numbers i.e. x = (-∞ , ∞).

When Tyee runs the 400 meter dash, his finishing times are normally distributed with a mean of 61 seconds and a standard deviation of 1.5 seconds. If Tyee were to run 39 practice trials of the 400 meter dash, how many of those trials would be faster than 62 seconds, to the nearest whole number?
Answers
To find out how many of the 39 practice trials would be faster than 62 seconds, we need to calculate the proportion of trials that fall within the range of more than 62 seconds.
We can use the z-score formula to standardize the values and then use the standard normal distribution table (also known as the z-table) to find the proportion.
The z-score formula is:
z = (x - μ) / σ
Where:
x = value (62 seconds)
μ = mean (61 seconds)
σ = standard deviation (1.5 seconds)
Calculating the z-score:
z = (62 - 61) / 1.5
z ≈ 0.6667
Now, we need to find the proportion of values greater than 0.6667 in the standard normal distribution table.
Looking up the z-score of 0.6667 in the table, we find the corresponding proportion is approximately 0.7461.
To find the number of trials faster than 62 seconds, we multiply the proportion by the total number of trials:
Number of trials = Proportion * Total number of trials
Number of trials = 0.7461 * 39
Number of trials ≈ 29.08
Rounding to the nearest whole number, approximately 29 of the 39 practice trials would be faster than 62 seconds.

And please clarify your answers in a simple language
Answers
Given the equations a × b = 5742 × 6368, a × c = 5748 × 6362, and c × b = 5738 × 6372, we need to determine the relationship between the three variables a, b, and c.
By comparing the given equations, we notice that the numbers on the right-hand side of each equation are very close to each other, differing only by small amounts. This suggests that a, b, and c are approximately equal.Since a × b, a × c, and c × b involve the same numbers with slight variations, we can conclude that a, b, and c are all very close in value.
Therefore, the inequality we can infer from this information is a ≈ b ≈ c, indicating that a, b, and c are approximately equal.
In simple terms, based on the given equations, it suggests that the values of a, b, and c are very similar or approximately equal to each other.

Use Pythagoras' theorem to calculate the length of FG. Give your answer in centimetres (cm) to 1 d.p. 8 cm H 13 cm G
Answers
The length of FG is approximately 15.3 cm.
To calculate the length of FG using Pythagoras' theorem, we need to find the length of the hypotenuse (FG) of a right triangle. Let's denote the length of FG as x.
According to Pythagoras' theorem, in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, we have:
\(FG^2 = GH^2 + FH^2\)
Given that GH = 8 cm and FH = 13 cm, we can substitute these values into the equation:
\(x^2 = 8^2 + 13^2\)
\(x^2 = 64 + 169\)
\(x^2\) = 233
To find x, we take the square root of both sides:
x = √233 ≈ 15.26 cm (rounded to 1 decimal place)
Therefore, the length of FG is approximately 15.3 cm.
