Find dy/dx by implicit differentiation. 3x + y = 8 + x2y2

Answers

Answer 1
3 +dy/dx = 0+ 2x²ydy/dx + 2xy²
dy/dx - 2x²ydy/dx = 2xy² -3
(1 - 2x²y) dy/dx = (2xy²-3)/(1-2x²y)
Answer 2
Final answer:

To find dy/dx by implicit differentiation, differentiate both sides of the equation with respect to x, apply the chain rule and product rule, isolate the terms involving dy, and simplify the equation to find dy/dx.

Explanation:

To find dy/dx by implicit differentiation, we need to differentiate both sides of the equation with respect to x. Using the chain rule and product rule, we can simplify the equation and solve for dy/dx. Starting with 3x + y = 8 + x^2y^2:

Step 1: Differentiate each term with respect to x.

Step 2: Apply the chain rule and product rule to simplify the equation.

Step 3: Solve for dy/dx by isolating the terms involving dy.

Step 4: Simplify the equation and rearrange to get dy/dx.

Answers

The proper perpendicular slope should be -1/4 instead of positive 1/4. The y intercept is also incorrect

Let's call the y intercept b for now
m = -1/4 is the perpendicular slope
(x,y) = (16,1) is the point the perpendicular line goes through
breaking this down further means x = 16 and y = 1 pair up together

y = mx+b
y = (-1/4)*x+b ... replace m with -1/4
y = (-1/4)*16+b .... replace x with 16
1 = (-1/4)*16+b .... replace y with 1
1 = -4+b ... multiply -1/4 and 16 to get -4
1+4 = -4+b+4 ... add 4 to both sides
5 = b
b = 5
So the y intercept is 5 (not 4)

since m = -1/4 and b = 5  we go from 
y = mx+b
to
y = (-1/4)x+5

So the final answer is y = (-1/4)x+5 which can be written as [tex]y = -\frac{1}{4}x+5[/tex]

As a check, we can plug x = 16 into the equation to get...
y = (-1/4)*x + 5
y = (-1/4)*16 + 5
y = -4 + 5
y = 1
so that confirms we have the right answer.

Lisa had 1750 stamps. Mark had 480 fewer stamps than Lisa. Lisa gave some stamps to Mark. Now Mark has three times as many stamps as Lisa. How many stamps did Mark have at first? How many stamps does Lisa have now? Explain.

Answers

Given that Lisa had 1,750 stamps and Mark had 480 fewer stamps than Lisa.

Thus, the number of stamps Mark had is 1,750 - 480 = 1,270

Given that Lisa gave some stamps to Mark which makes Mark to have three times as many stamps as Lisa.

Let the number of stamps that Lisa gave to Mark be x, then

[tex]3(1,750 - x) = 1,270 + x \\ \\ \Rightarrow5,250-3x=1,270+x \\ \\ \Rightarrow x+3x=5,250-1,270 \\ \\ \Rightarrow 4x=3,980 \\ \\ \Rightarrow x= \frac{3.980}{4} =995[/tex]

Thus, Lisa gave Mark 995 stamps.

Therefore, the number of stamps that Lisa have now is 1,750 - 995 = 755.

Pi × radius^2. Radius=20 m Pi × 20^2 Area= 400pi m^2

Answer:  The required area of the given circle is [tex]400\pi~\textup{m^2}.[/tex]

Step-by-step explanation:  We are given that the diameter of a circle i 40 m.

We are to find the area of the circle in terms of pie.

We know that

the AREA of a circle with radius of length r units is given by

[tex]A=\p r^2.[/tex]

Since the diameter of the given circle is 40 m, so the length of the radius is given by

[tex]r=\dfrac{40}{2}=20~\textup{m}.[/tex]

Therefore, the AREA of the circle is given by

[tex]A=\pi r^2=\pi\times 20^2=400\pi~\textup{m}^2.[/tex]

Thus, the required area of the given circle is [tex]400\pi~\textup{m}^2.[/tex]

What is the volume in cubic yards of a greenhouse that is 35 feet long, 10 feet wide, and 10 feet high?

Answers

Final answer:

To determine the volume of a greenhouse, multiply its length, width, and height to find its volume in cubic feet, then convert to cubic yards using the conversion factor of 1 cubic yard being equivalent to 27 cubic feet. The volume for the given dimensions is approximately 129.63 cubic yards.

Explanation:

The volume of a structure, including a greenhouse, is calculated by multiplying its length by its width by its height. The first step is to calculate the volume in cubic feet, then convert cubic feet to cubic yards knowing that 1 cubic yard equals 27 cubic feet. Here's how to calculate the volume of the given greenhouse:

Multiply the length, width, and height in feet to get the volume in cubic feet: 35 ft x 10 ft x 10 ft = 3500 cubic feet.Convert cubic feet to cubic yards using the conversion factor (1 cubic yard = 27 cubic feet): 3500 cubic feet
divided by

27 = 129.63 cubic yards.

Therefore, the volume of the greenhouse is 129.63 cubic yards.

Find p((5 on green die and 3 on red die) or (3 on green die and 5 on red die)). (enter your answer as a fraction.)

Answers

1/72 This is because the odds that, on two dice, two specific numbers get rolled is 1/36. But since the number has to be rolled on a specific dice, that doubles the fraction.

The probability of rolling a 5 on the green die and a 3 on the red die, or a 3 on the green die and a 5 on the red die is calculated by summing their individual probabilities, leading to a final probability of 1/18.

To solve this probability question, we will use the fundamental counting principle and basic probability rules. We have two six-sided dice, one green and one red. The question specifies two separate events:

The green die shows a 5 and the red die shows a 3.

The green die shows a 3 and the red die shows a 5.

Since each face on a fair six-sided die has an equal chance of appearing, the probability of getting any specific number is 1/6. When we roll two dice, the probability of any specific outcome is (1/6) x (1/6), which simplifies to 1/36.

Since there are two independent events that satisfy the question, we can add the probabilities of each event occurring:

Probability of a 5 on green die and 3 on red die = 1/36

Probability of a 3 on green die and 5 on red die = 1/36

Adding them up, we get 1/36 + 1/36 = 2/36, which simplifies to 1/18. Therefore, the probability of getting either a (5 on the green die and 3 on the red die) or (3 on the green die and 5 on the red die) is 1/18.

calculate gas mileage of car that drives 283 miles on 12.3 gallons of gas andround to nearest tenth of a mpg

Answers

283 divided by 12.3 = 23.008 and rounded it will just be 23.
Final answer:

The gas mileage of a car that drives 283 miles on 12.3 gallons of gas is approximately 23.0 miles per gallon, when rounded to the nearest tenth.

Explanation:

Gas mileage is determined by dividing the total miles driven by the gallons of gas consumed. In this scenario, 283 miles were covered using 12.3 gallons of gas. The calculation yields approximately 22.97 miles per gallon (mpg), but rounding to the nearest tenth results in 23.0 mpg. This figure represents the efficiency of the vehicle in terms of fuel consumption, offering a quick and easy measure for assessing its economic and environmental impact. Monitoring gas mileage is crucial for budgeting and understanding the ecological footprint of transportation choices, promoting conscientious and efficient use of fuel resources.

Lisa wants to buy a phone card for $5. Company X charges $0.49 for the first minute and $0.16 for each additional minute. Company Y charges $0.57 for the first minute and $0.12 for each additional minute. If Lisa makes just one call, which phone company gives her more minutes for $5? How many more minutes?

Answers

So for $5, let's calculate each company's minutes for that much money.

Company X: First subtract the time for the first minute.

5 - 0.49 = 4.51

Then divide by 0.16, and you get about 28 minutes.

28 + the original 1 minute = 29 minutes

Company Y: $5 - 0.57 = 4.43

4.43 / 0.12 = about 36 + the original one minute = 37 minutes

So Company Y gives her more minutes for 5 dollars, and also 8 more.
