The value of derivative dx/dt = 12t³ and dy/dt = 4-2t.
To find the derivatives of x and y as functions of t, we'll calculate dx/dt and dy/dt.
For x=3t⁴, the derivative dx/dt is 12t³. For y=4t-t², the derivative dy/dt is 4-2t.
Now, let's break down the steps in the explanation:
1. Identify the functions x and y: x=3t⁴, y=4t-t².
2. Calculate the derivative of x with respect to t:
dx/dt = d(3t⁴)/dt = 3 * d(t⁴)/dt = 3 * (4t³) = 12t³.
3. Calculate the derivative of y with respect to t:
dy/dt = d(4t-t²)/dt = d(4t)/dt - d(t²)/dt = 4 - 2t.
4. Write the final derivatives: dx/dt = 12t³, dy/dt = 4-2t.

Choose the correct verb form that completes this sentence: Nosotros _____ la ventana. Select one: a. compartimos b. abro c. escribimos d. abrimos
Answer: abrimos
Step-by-step explanation: That's what it is on my quiz.
In the sentence "Nosotros _____ la ventana", the correct verb form is "abrimos". The best answer is option D.
The verb "abrir" is a Spanish verb that means "to open", and the first person plural form of this verb is "abrimos". So the sentence "Nosotros abrimos la ventana" translates to "We open the window".
The other verb forms in the options ("compartimos", "abro", and "escribimos") do not fit the context of opening the window. "Compartimos" means "we share", "abro" means "I open" (first person singular), and "escribimos" means "we write". So these forms are not the correct form to complete the sentence.

At her ranch, Georgia starts an animal shelter to save cats. After the first three days, she has 34 male cats and 13 female cats. She decides to only accept cats in male-female pairs from then on. In this problem, we find the largest number of pairs of cats she can accept to her shelter and still have at least 60% of her dogs be male.
(a) Let d be the number of pairs of cats she accepts. How many male cats will she have total? Female cats? Total cats?
(b) Write an inequality that means that the percentage of cats at her shelter that are male is at least 60%.
(c)Solve the inequality and determine the largest number of pairs of animal she can accept to her shelter and still have at least 60% of her dogs be male.
Step-by-step explanation:
I know that both sides of the cats, males and females, receive the same # of new cats.
I write an equation, (not an inequality though):
3((34+2x)/5)=2((13+2x)/5)
From here on, I solve for x. I get x = -38. I know we can't have negative pairs and we're only bringing in more cats, and not taking any away. I add 38, and try to see what percentage of cats are male, and I get fairly close, getting to about 62.5% I think. Then, I divide 38 by 2, getting 19, and see what else I can get. I try to find a value between the 38 and lesser 19 so as to find a value which will give me a male cat percentage of 60%. I get about 57.5% with 19 plugged in, which is when I see that hey, the differences are the same. What I then do is find the average of 19 + 38, which is 57.5. I round that to 58, and I get the right answer.
I see that perhaps my solution wasn't really orthodox or anything, but with a little bit of trial and error and a bit of my creative thinking, I guess I managed to solve the problem. What worries me though is this is the first problem in the "questions" section of the inequalities section of AoPS, so I'm definitely struggling to deal with the concepts.

The number π is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159.It is an irrational number, meaning that it cannot be expressed exactly as a ratio of two integers, although fractions such as 22/7 are commonly used to approximate it. Consequently, its decimal representation never ends, nor enters a permanently repeating pattern. It is a transcendental number, meaning that it cannot be a solution of an equation involving only sums, products, powers, and integers.The transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straightedge.

Describe the transformation that is needed to obtain the graph of g(x)=3x−5 from the graph of g(x)=3x
Answer:
The graph of g(x) = 3x−5 is obtained from the graph of g(x) = 3x by applying the transformation (f(x) = f(x) + b) where b = -5. This transformation is a vertical shift of the graph of g(x) = 3x downward by 5 units.
The graph of g(x) = 3x is a line with a slope of 3 and y-intercept of 0. By subtracting 5 from each y-coordinate, the y-intercept of the graph is shifted downward by 5 units, resulting in a y-intercept of -5. The slope of the graph remains the same as the original function, 3. So the graph of g(x)=3x−5 is the same line as g(x)=3x, but shifted downward 5 units.

The owner of Nuts2U Snack Shack mixes cashews worth $6.25 a pound with peanuts worth $2.10 a pound to get a half-pound mixed nut bag worth $1.90. How much of each kind of nut is included in the mixed bag?
Answer:
I have solved it and attached in the explanation.
Step-by-step explanation:
The amount of Cashew nuts is 0.205
The amoun of Peanuts is 0.295
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Amount of Cashew nuts = x
Amoun of Peanuts = y
Now,
We can make two equations.
x + y = 1/2 ____(1)
x = 1/2 - y _____(20
Substituting (2) in (3)
6.25x + 2.10y = 1.90 _____(3)
6.25 (1/2 - y) + 2.10y = 1.90
3.125 - 6.25y + 2.10y = 1.90
3.125 - 4.15y = 1.90
3.125 - 1.90 = 4.15y
y = 1.225/4.15
y = 0.295
And,
x = 1/2 - y
x = 1/2 - 0.295
x = 0.205
Thus,
Amount of Cashew nuts = 0.205
Amoun of Peanuts = 0.295
