Option b) p = -8 is correct, when p³ = 518.
Define cube root.A integer y such that y3 = x is known as the cube root of a number x in mathematics. All nonzero complex numbers have three different complex cube roots, while all nonzero real numbers have exactly one real cube root and two complex conjugate cube roots. We are aware that adding three times to any number yields the cube of that number. Additionally, the inverse action of cubing a number is known as the cube root of a number. For instance, 63 has a cube value of 216. In that case, 216's cube root is equal to 6.

The equation that would represent the gold medals won by the United States is 1 + 4F = 7 + F.
The gold medals won by France is 2.
The gold medals won by the United State is 9.
How many gold medals were won by each country?The equation that would represent the gold medals won by the United States would be a linear function. A linear function is a function that has a single variable that is raised to the power of one. A linear equation is a straight line that slopes either upward or downward when drawn on a coordinate plane.
The equation that represents the gold medals won by the United States is:
1 + ( 4 x F) = 7 + F
1 + 4F = 7 + F
In order to determine the value of F, take the following steps:
Combine similar terms together: 4F - F = 7 - 1
Add similar terms: 3F = 6
Divide both sides of the equation by 3 : F = 6 / 3
F = 2

What is the quotient of 1.232 x 10⁸ and 3.85 x 10 expressed in scientific notation?
Answer:
3.2 x 10⁶
Explanation:
Given the quotient:
[tex]\frac{1.232\times10^8}{3.85\times10}[/tex]We can rewrite the expression by removing the decimals as follows:
[tex]=\frac{1232\times10^{-3}\times10^8}{385\times10^{-2}\times10}[/tex]Next, we rewrite the powers of 10 so we can cancel out common terms.
[tex]\begin{gathered} =\frac{1232}{385}\times\frac{(10^{-2}\times10^{-1})\times(10\times10^7)}{10^{-2}\times10} \\ \frac{1232}{385}\times10^{-1}\times10^7 \end{gathered}[/tex]Next, express the first fraction in the lowest possible form:

In a sale, normal prices are reduced by 10%.
David bought a pair of trainers in the sale for £36.
What was the original price of the trainers?
In a sale, if the normal prices are reduced by 10% and David bought a pair of trainers in the sale for £36 then the marked price of these trainers was £40.
What is original price?Original price is said to be as the price that was fixed by the MSRP (i.e said to be the Manufacturer’s Suggested Retail Price).
In most of the case scenario, the original price would taken to be as always lower than the current price and then also in some other cases, original price and current price can be taken as the same.
How do you calculate the original price?First you have to convert the total percent discount to a decimal by dividing by 100% . Step 2: Set up the equation P=(1−d)x P = ( 1 – d ) x to find the original price of the item where P is the sale price, d is the discount as a decimal, and x is the original price of the item.
The selling price, may be that of a product or a service, is said to be as the customer or client’s final price
How do you find the original price from a discounted price calculator?To calculate the exact original price of a selected item, you have to divide the sale price by the value of 1 minus the entire value of the percentage off and then divided by 100.

Speed of Driver A is 30 km/h.
Speed of Driver B is 40 km/h
Define speed.The speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.
Given Data
Driver A and B have two different routes. Driver A's route is 80km, and driver B's route is 100km. Driver B travels 10km/h faster than driver A and finishes 10 minutes earlier.
Distance = Speed (Time)
Distance for Driver A: 80 kilometers
Consider Driver A's speed to be A km/h.
Driver A's time was [tex]\frac{80}{A}[/tex] hours.
Distance for Driver B is 100 kilometers
Speed of Driver B: A + 10 km/h
Driver B's time was equal to 100/(A + 10) hours.
Arrived 10 minutes early, or [tex]\frac{10}{60}[/tex], or [tex]\frac{1}{6}[/tex]hour.
100/(A + 10) = [tex]\frac{80}{A}[/tex] - [tex]\frac{1}{6}[/tex]

Write an equation of the line that passes through the pair of points (-4,-6) (5,-6)
The equation of the line passing through (-4,-6), (5,-6) will be y = -6
In the given question, it is stated that the line passes through points (-4,-6), and (5,-6). We need to find out an equation of the line that satisfies the given condition.
Firstly, we will need to find out the slope of the line. We can find the slope by using the point-slope form which is represented by:
=> [tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]
Putting values (x₁, y₁) = (-4,-6) and (x₂, y₂) = (5,-6) we get:
=> [tex]m = \frac{-6+ 6 }{5+ 4 }[/tex]
=> m = 0
We get slope m = 0. Now, putting the value of slope into the point-slope form and taking (x₁, y₁) = (-4,-6), we get values:
=> y - y₁ = m(x - x₁)
=> y + 6 = 0(x + 4)
=> y = -6
Hence, we get the equation of line y = -6

What is the graph of 5y- 15x =30
A graph of this linear function (y = 3x + 6) is shown in the image attached below.
What is a graph?A graph can be defined as a type of chart that is commonly used for the graphical representation of data on both the horizontal line (x-axis) and vertical line (y-axis) of a cartesian coordinate.
Next, we would simplify the given linear function by dividing all through by 5 as follows:
5y - 15x = 30
5y/5 - 15x/5 = 30/5
y - 3x = 6
Rearranging the linear function, we have:
y = 3x + 6
In this context, we can reasonably and logically deduce that only the graph of a proportional relationship such as a linear function is always characterized by a straight line with all of the data points passing through the origin (0, 0).
In conclusion, a graph which represents the given linear function does not show a proportional relationship between the value of x and y.

The hypotenuse of a right-angled triangle is 1 cm longer than twice the shorter side and is 2 cm longer than the other side.
Find the perimeter of the triangle.
Answer:
The perimeter is 40 cmStep-by-step explanation:
Let the sides be:
Hypotenuse = a,Short leg = b,Long leg = c.According to question are given:
a = 2b + 1 ⇒ b = (a - 1)/2,a = c + 2 ⇒ c = a - 2.Use Pythagorean to find the length of hypotenuse:
a² = b² + c²a² = [(a - 1)/2]² + (a - 2)²a² = (a² - 2a + 1)/4 + a² - 4a + 40 = (a² - 2a + 1)/4 - 4a + 4a² - 2a + 1 - 16a + 16 = 0a² - 18a + 17 = 0a² - a - 17a + 17 = 0a(a - 1) - 17(a - 1) = 0(a - 1)(a - 17) = 0a - 1 = 0 and a - 17 = 0a = 1 and a = 17The first option is discarded, as all sides should be positive. With a = 1 we get negative value for c.
So a = 17 cm.
Find the other sides:
b = (17 - 1)/2 = 8 cmc = 17 - 2 = 15 cmFind the perimeter:
P = a + b + c = 17 + 8 + 15 = 40 cmAnswer:
40 cm
Step-by-step explanation:
Pythagoras Theorem
[tex]a^2+b^2=c^2[/tex]
where:
a and b are the legs of the right triangle.c is the hypotenuse of the right triangle.Let a be the shorter leg.
If the hypotenuse is 1 cm longer than twice the shorter side then:
[tex]\implies c = 2a + 1[/tex]
If the hypotenuse is 2 cm longer than the other side then:
[tex]\implies c = b + 2[/tex]
Equate the two expressions for c and solve for b:
[tex]\implies b+2=2a+1[/tex]
[tex]\implies b=2a-1[/tex]
Substitute the expression for c involving a, and the expression for b involving a, into Pythagoras Theorem and solve for a:
[tex]\implies a^2+(2a-1)^2=(2a+1)^2[/tex]
[tex]\implies a^2+4a^2-4a+1=4a^2+4a+1[/tex]
[tex]\implies a^2-4a=4a[/tex]
[tex]\implies a^2-8a=0[/tex]
[tex]\implies a(a-8)=0[/tex]
[tex]\implies a=0, \quad a=8[/tex]
Since the length of a side cannot be zero, a = 8.
The perimeter of a two-dimensional shape is the distance around the outside. Therefore, the perimeter of the triangle is the sum of its sides:
[tex]\begin{aligned} \implies \textsf{Perimeter}&=a+b+c\\&=a+(2a-1)+(2a+1)\\&=5a\end{aligned}[/tex]
Substitute the found value of a into the expression for the perimeter:
[tex]\begin{aligned} \implies \textsf{Perimeter}&=5(8)\\&=40\sf \; cm\end{aligned}[/tex]
Therefore, the perimeter of the triangle is 40 cm.
