Let V=ℝ3 and let H be the subset of V of all points on the plane 7x−3y+6z=−21. Is H a subspace of the vector space V?

Answers

No, H doesn't have the zero vector, since

7•0 - 3•0 + 6•0 = 0 ≠ -21

so H is not a subspace of V.

The function f(x,y) = x² + y² has a minimum value of 0 at the point (0,0) and has no maximum value.

What is a function?

A function is a relation between a set of inputs and a set of possible outputs, with the property that each input is related to exactly one output.

The function f(x,y) = x² + y² represents the sum of the squares of the variables x and y. To find the extreme values of this function, we need to take the partial derivatives with respect to x and y and set them equal to zero.

∂f/∂x = 2x = 0

∂f/∂y = 2y = 0

From these equations, we can see that the critical point occurs at (x,y) = (0,0).

To determine whether this is the maximum or minimum, we can use the second partial derivative test. The second partial derivatives are:

∂²f/∂x² = 2

∂²f/∂y² = 2

∂²f/∂x∂y = 0

At (0,0), ∂²f/∂x² > 0 and ∂²f/∂y² > 0, so the critical point is a minimum.

Therefore, the function f(x,y) = x² + y² has a minimum value of 0 at the point (0,0) and has no maximum value.

About % of babies born with a certain ailment recover fully. A hospital is caring for babies born with this ailment. The random variable represents the number of babies that recover fully. Decide whether the experiment is a binomial experiment. If it is, identify a success, specify the values of n, p, and q, and list the possible values of the random variable x. Is the experiment a binomial experiment?

Answers

Answer:

This is a binomial experiment .

Step-by-step explanation:

As the percent is not indicated the success is the amount of percent (if given) say it is 10 % . So p will be equal to = 0.1 and q will be = 1-0.1= 0.9

and n would be five or any number as a binomial experiment is repeated for a fixed number of times.

And x would take any value of n i.e.

X= 0,1,2,3,4,5

If it is 20 % . So p will be equal to = 0.2 and q will be = 1-0.2= 0.8

The probability is the number of the percent indicated. But as it is not indicated we assume it to be 10 % or 20 % .Or suppose any number for it to be a binomial experiment.

The number of trials n would be fixed .

The success remains constant for all trials.

All trials are independent.

Pablo used a total of 5 3/4 gallons of gas while driving his car. Each hour he was driving, he used 5/6 gallons of gas. What was the total number of hours he was driving? Write your ans

Answers

Let x be the number of hours Pablo was driving.

We know that he used 5/6 gallons of gas per hour of driving.

So, the total amount of gas he used is 5/6 * x.

We also know that he used a total of 5 3/4 gallons of gas.

So, we can set up the equation:

5/6 * x = 5 3/4

To solve for x, we can first convert 5 3/4 to an improper fraction:

5 3/4 = 23/4

Then, we can multiply both sides of the equation by the reciprocal of 5/6:

x = (5 3/4) / (5/6)

x = (23/4) / (5/6)

x = (23/4) * (6/5)

x = 27.6/4

x = 6.9

Therefore, Pablo was driving for a total of 6.9 hours.

The perimeter of the pond is 2.92 meters.

What s a right-angle triangle:

A right-angled triangle is a triangle in which one of the angles measures exactly 90 degrees, also known as a right angle.

The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs.

The perimeter of a right-angled triangle is the sum of the lengths of its three sides.

Here we have

The Hypotenuse of the triangle is 1.46 m

The angle between hypotenuse and perpendicular height = 73°

From triagonometric ratios,

=> cos A = Perpendicular height/ Hypotenuse.

=> cos (73) = Perpendicular height/1.46

=> Perpendicular height = 1.46 × 0.29 = 0.42 m

As we know from Pythagoras' theorem,

Hypotenuse² = side² + side²

Side = √Hypotenuse² - side²

= √[(1.46)²- (0.42)²] = 1.04

Therefore, the sides of the pond are 1.46 m, 0.42 m, and 1.04

Hence, perimeter of the pond = 1.46 + 0.42 + 1.04 = 2.92 meters

Therefore,

The perimeter of the pond is 2.92 meters.

How many particles in
9.89 moles of Carbon?

Answers

The number of particles in 9.89 moles of carbon is solved to be

5.95 x 10^24 particles

How to find the number of particles in 9.89 moles of carbon

To determine the number of particles in 9.89 moles of carbon, we can use Avogadro's constant, which is defined as the number of particles (atoms or molecules) in one mole of a substance.

Avogadro's constant is approximately 6.02 x 10^23 particles per mole.

So, the number of particles in 9.89 moles of carbon is:

= 9.89 moles x (6.02 x 10^23 particles/mole)

= 5.95 x 10^24 particles

Therefore, there are approximately 5.95 x 10^24 particles in 9.89 moles of carbon.

A system of equations is made up of an ellipse and a hyperbola.

Answers

Ok, so

We want to find the equation of an ellipse centered at the origin with a horizontal major axis of 8 units and a minor axis of 6 units.

For this, let's remember the form of the equation of an ellipse:

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1$

Where the center of the ellipse is located at the point (h,k).

If the ellipse is centered at the origin, then, h=0 and k=0, so the form of our equation will be:

$\frac{x^2}{a^2}+\frac{y^2}{b^2}=1$

Now, we're given that our ellipse has a horizontal major axis of 8 units and a minor axis of 6 units. Since the major and minor axis are given by the parameters 2a and 2b, then, a=4 and b=3. the greater number will divide the x² term and a>b.

So, the equation of this ellipse is:

$\frac{x^2}{16}+\frac{y^2}{9}=1$

The graph of this ellipse will be something like:

Answers

Each half hour, the candle burns away 3/4 inch of its length. Therefore, after 1 hour, the candle would have burned away 1.5 inches (2 half-hour periods * 3/4 inch burned in each period), leaving it with a length of 0.5 inches.

After 2 hours, the candle would have burned away another 1.5 inches (4 half-hour periods * 3/4 inch burned in each period), leaving it with a length of 0 inches. At this point, the candle has completely burned down.

Therefore, after 4 hours, the length of the candle would be 0 inches.

Work out how far from town A they will be when they pass each other

Answers

They will be when they pass each other at 44 4/9 mins.

This is a classic question on Speed, time, & distance.

1. When time traveled in each segment is constant, then average speed is simple mean of speeds.

2. When distance traveled in each segment is constant, then average speed is reciprocal of simple mean of reciprocal of speeds. It is basically called Harmonic mean.

So this question falls in the category of 2.

=> So, average speed = Reciprocal of mean of reciprocals of 40 & 50.

=> Average speed = Reciprocal of mean of 1/40 & 1/50.

=> Average speed = Reciprocal of (1/40 + 1/50)/2

= Reciprocal of (5+4)/400

= 44 4/9 mins

Hence, they will be when they pass each other at 44 4/9 mins.
