Step-by-step explanation:
Answer:
If x^3+1\x^3=18, then what is the value of x?
x^3 +1/x^3= 18.
Formula:-
(x +1/x)^3 = x^3. +1/x^3 + 3.(x +1/x).
Let (x+1/x)= p.
or, p^3 =18 +3p.
or, p^3 -3.p -18 =0.
Putting p=3 , remainder = 3^3–9–18 = 0 , (p-3) is a factor.
or, p^2.(p-3)+3.p^2-3p-18=0
or, p^2.(p-3)+3.p.(p-3)+6.(p-3)=0.
or, (p-3).(p^2+3p+6)=0
Either p-3=0.
or, p = 3. , putting p = x +1/x.
or, x +1/x = 3. ……………….(1).
And, (x -1/x)^2 = (x+1/x)^2 - 4. = 3^2 - 4 = 5.
Thus, x -1/x = +/-√5. …………….(2).
Adding eqn.(1) and (2).
2.x = 3+/-√5.
or, x = (3+/-√5)/2. Answer.

Answer:
4 inches wide
Step-by-step explanation:
We see that 984 ÷ 328 = 3, so the real Eiffel Tower is 3 times as tall as it is wide. So the scale model must also be 3 times as tall as it is wide. If the scale model is 12 inches tall, then it is 12 ÷ 3 = 4 inches wide.

The answer is 8 so its a direct proportion
I think...
The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

Answer the questions below:
The circumference of the scaled copy is twice the circumference of the original circle.
The area of the scaled copy is four times the area of the original circle.
How to draw a scaled copy of the circle using a scale factor of 2?
a. To draw a scaled copy of the circle with a scale factor of 2, multiply the radius of the original circle by 2, and then draw a circle with this new radius centered at the same point as the original circle.
For example, if the original circle has a radius of 4 units, the scaled copy will have a radius of 2 × 4 = 8 units.
b. The circumference of a circle is given by the formula C = 2πr,
where C is the circumference and r is the radius of the circle.
Thus, the circumference of the original circle is C₁ = 2πr₁ and the circumference of the scaled copy is C₂ = 2πr₂.
Since the scale factor is 2, we have r₂ = 2r₁, so the circumference of the scaled copy is C₂ = 2π(2r₁) = 4πr₁ = 2C₁.
This means that the circumference of the scaled copy is twice the circumference of the original circle.
c. The area of a circle is given by the formula A = πr²,
where A is the area and r is the radius of the circle.
Therefore, the area of the original circle is A₁ = πr₁² and the area of the scaled copy is A = πr₂²
Since the scale factor is 2, we have r₂ = 2r₁, so the area of the scaled copy is A₂ = π(2r₁)² = 4πr₁ ² = 4A₁ . This means that the area of the scaled copy is four times the area of the original circle.

Step-by-step explanation:
For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:
4 eggs were left over
Step-by-step explanation:
initial number of eggs = 12
number of eggs used to bake 1 loaf of challah:
= 2 eggs
total number of eggs used to bake 4 loaves of challah:
= 4 × 2 = 8 eggs
hence to find the number of remaining eggs:
initial egg number - total number of eggs used
= 12 - 8
= 4
therefore 4 eggs were left over

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)
