Write an equation that shows how the width (w) depends on the length (l) for rectangles with an area of 24inches squared.
Write 4 equations.
Thank you so much and if you can explain!
The equation that shows how the width depends on the length for rectangles with an area of 24 inches squared is w = 24/l.
Explanation:To find the equation that shows how the width (w) depends on the length (l) for rectangles with an area of 24 inches squared, we need to set up a proportion using the formula for the area of a rectangle. The area of a rectangle is equal to the length multiplied by the width, so we have the equation: l * w = 24.
Now let's solve for w in terms of l:
Divide both sides of the equation by l: w = 24/lSo the equation that shows how the width depends on the length for rectangles with an area of 24 inches squared is: w = 24/l.By substituting different values for l, we can find corresponding values for w and see how they are related.

Which point is a solution to the inequality shown in this graph? (0,1) (3,-1)
All points in the shaded area are answers to the inequality. Thus you need to find the point which is in the shaded area of the graph.
Only the point (3, -1) is within range. Thus answer D is correct.
Answer:
Option D, (3, -1)
Step-by-step explanation:
In the inequality shown in the graph all the points which lie above the line (in the shaded part) will be the solution.
Option A) (0, -5)
Since this point lies below the line so it is not the solution.
Option B) (0, 0)
It's below the line again therefore not the solution.
Option C) (5, -5)
It lies below the line. Therefore it is not the solution.
Option D. (3, -1)
This point lies on the line therefore satisfies the condition.
Therefore Option D. (3, -1) is the only solution.

Could someone please list all of the basic derivative rules?
Answer:
The sum rule is f' + g'
The difference rule is f' − g'
The product rule is f g' + f' g
The quotient rule is (f' g − g' f )/g2
Final answer:
The basic rules for computing derivatives include the Constant, Power, Constant Multiple, Sum, Difference, Product, Quotient, and Chain rules. These rules are crucial for finding the rate of change of functions and can be applied in various combinations to handle more complex functions.
Explanation:
Basic Derivative Rules
When calculating derivatives, there are several basic rules that are often used. These are foundational tools in calculus that help us find the rate at which functions change. Here's a list of the basic derivative rules:
Constant Rule: The derivative of a constant is zero.
Power Rule: For any real number n, the derivative of xⁿ is [tex]nx^{(n-1)}[/tex]. This rule can be applied multiple times to terms that are added together, yielding the sum of their derivatives.
Constant Multiple Rule: The derivative of a constant multiplied by a function is the constant multiplied by the derivative of the function.
Sum Rule: The derivative of a sum of functions is the sum of the derivatives of each function.
Difference Rule: The derivative of a difference of functions is the difference of the derivatives of each function.
Product Rule: The derivative of the product of two functions is the first function times the derivative of the second plus the second function times the derivative of the first.
Quotient Rule: The derivative of a quotient of two functions is the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the square of the denominator.
Chain Rule: The derivative of a composite function can be found by taking the derivative of the outer function evaluated at the inner function, and then multiplying it by the derivative of the inner function.
Each of these rules follows our intuition about how functions change and can be confirmed through examples and experiences. We can use these rules to methodically find derivatives of more complex functions.

How many yards does a band member move across the football field if he or she takes 30 1/2 steps?
5/8⋅30 1/2=
Express your answer as a fraction in simplest form.
After taking 30 1/2 steps, each covering 5/8 yard, a band member moves a total of 19 1/16 yards across the football field.
Explanation:The student asks how many yards a band member moves across the football field if he or she takes 30 1/2 steps where each step covers 5/8 yard. To find the total distance covered, we multiply the number of steps by the distance per step. Here's the calculation:
First, convert 30 1/2 to an improper fraction: (30 × 2) + 1 = 61/2.Now, multiply 61/2 by 5/8 to find the total yards covered: (61/2) × (5/8) = 305/16.To simplify, divide 305 by 16: the quotient is 19 with a remainder of 1, so the simplified fraction is 19 1/16 yards.The band member moves 19 1/16 yards across the football field after taking 30 1/2 steps at a 8-to-5 step interval.
The price of a mountain bike increased by 20% in the past year the value is $150 what was the value of the mountain bike last year
I hope I am reading the problem right: The price of a mountain bike increased by 20% in the past year. The value is $150. What was the value of the mountain bike last year?
Let's simplify this. One year, there was this radical mountain bike that used to have an unsaid price, x. That year, that price of x increased by 20% more than it was before, or 120% times the original value. Because of that, it's now $150.
We can equation this.
1.20x = 150
x = 150/1.2
x = 125
The bike, I believe, cost $125 last year. Hope this helps!
Final answer:
To find the value of the mountain bike last year, we can use the concept of percentage increase and decrease.
Explanation:
To find the value of the mountain bike last year, we can use the concept of percentage increase and decrease. If the price of the bike increases by 20%, then the current value is 120% of the previous value.
To find the previous value, we can set up an equation: 120% of the previous value is equal to $150. Mathematically, this can be written as 1.2x = 150, where x is the previous value.
Solving the equation, we divide both sides by 1.2 to isolate x: x = $125. Therefore, the value of the mountain bike last year was $125.
