I really need help!!

Answer:

none of these

Step-by-step explanation:

none of these is the correct answer because if this is pemdas it would be 24.818

and if it is not pemdas it would still be 3.818.

The way pemdas would be solved is 62 divided by 22 first which is 2.818

and then 2.818 + 22 which= 24.818.

But if your just doing it in order and it isn't pemdas than you would do 22 + 62 which=84 and then 84 divided by 22=3.818

So your answers are wrong I wanted to let you know that is there an option od none of theres or is there more to the question I can help you with.

I hope I can help and that this helps have a awesome day:)

Infinitely many position vectors with length 2 in xyz-space are orthogonal to the nonzero position vector v. (D)

A position vector in xyz-space is a vector that starts at the origin and ends at a point in xyz-space. The length of a position vector is the distance from the origin to the point it ends at.

If we want to find position vectors with length 2 that are orthogonal (perpendicular) to a given nonzero position vector v, we can use the dot product.

Let w be a position vector with length 2 that is orthogonal to v. Then, the dot product of v and w must be zero, since they are orthogonal. That is, v · w = 0. Since the length of w is 2, we can write w as 2u for some unit vector u. Thus, v · w = v · (2u) = 2(v · u) = 0.

This means that v and u are orthogonal as well, since the dot product of two vectors is zero if and only if they are orthogonal.

There are infinitely many unit vectors u that are orthogonal to v, and therefore, there are infinitely many position vectors with length 2 that are orthogonal to v. Therefore, the answer is (d) infinitely many.

Answer:

(-0.5,2.5)

Step-by-step explanation:

The given equations are ,

\(\implies x + y - 2 = 0 \)

\(\implies 3x - y +4 = 0 \)

The point of intersection will be the solution of the given system of equations. Adding both , y will get cancelled . So that ,

\(\implies 4x +2 = 0 \)

Now solve for x , we have ,

\(\implies 4x = -2 \\\\\implies x =\dfrac{-2}{4}\\\\\implies x = -0.5 \)

Now put this value in any equation and solve out for y , we have ,

\(\implies -0.5 + y - 2 = 0 \\\\\implies y = 2.5 \)

Therefore , the point of intersection will be ,

Step-by-step explanation:

The mean of the numbers in the list is 16.

A. To work out the numbers in the list, we simply list the given numbers:

17, 21, 14, 17, 12, 15, 16.

B. To work out the mean of the numbers in the list, we sum up all the numbers and divide by the total count.

Mean = (17 + 21 + 14 + 17 + 12 + 15 + 16) / 7

Calculating the sum: 17 + 21 + 14 + 17 + 12 + 15 + 16 = 112

Now, dividing the sum by the count:

Mean = 112 / 7 = 16.

Mean, also known as the average, is a measure of central tendency that represents the typical or average value of a set of numbers.

It is calculated by summing up all the numbers in the set and then dividing the sum by the total count of numbers in the set.

Mathematically, the mean is represented as:

Mean = (Sum of all numbers) / (Total count of numbers).

Well for every 1/2 cup of sugar its 1 cup of flour

Step-by-step explanation:

Just make a table like for example 5 1/2 cup of sugar brings you 11 cups of flour

Anoter example could be 5.5 cups of flour could be 3 cups of sugar yk?

For 3/4 cups of sugar. 3/2 cups of flour will be added,7/2 cups of sugar is added for  \(1\frac{3}{4}\)  cups of flour, 1 cup of sugar, 2 cups of flours is added and 5 cups of sugar is added for \(2\frac{1}{2}\) cups of flour.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

A recipe calls for 1/2 cup sugar and 1 cup flour

Now we need to calculate for 3/4 cups of sugar how much of flour should be added.

Let the flour will be x

1/1/2=x/3/4

2/1=4x/3

Apply cross multiplication

6=4x

x=6/4

x=3/2

So for 3/4 cups of sugar. 3/2 cups of flour will be added.

Now for \(1\frac{3}{4}\)  cups of flour, the amount of sugar added is

7/4/2=14/4=7/2

So 7/2 cups of sugar is added for  \(1\frac{3}{4}\)  cups of flour

For 1 cup of sugar, 2 cups of flours is added.

Now for \(2\frac{1}{2}\) cups of flour, the amount of sugar added is

5/2/2=10/5=5

5 cups of sugar is added for 2 1/2 cups of flour.

Hence for 3/4 cups of sugar. 3/2 cups of flour will be added,7/2 cups of sugar is added for  \(1\frac{3}{4}\)  cups of flour, 1 cup of sugar, 2 cups of flours is added and 5 cups of sugar is added for \(2\frac{1}{2}\) cups of flour.

The empire state building is taller than a chair seat by three orders of magnitude.

Orders of magnitude refer to the classification based on the sizes of two objects against each other.

Orders of magnitude range in the power of 10 or 10ⁿ.

Orders of Magnitude:

100x = 2nd order of magnitude

1000x = 3rd order of magnitude

Empire State Building = 1,500 feet

Chair seat = 1.5 feet

The equation of the line that contains the point (3,-4)and has a slope of 5/7 is 7y = 5x-43

When two points on a line, we can write an equation for that line by finding the slope between those points, then solving for the y-intercept in the slope-intercept equation y=mx+b.

Given that, a line contains the point (3,-4)and has a slope of 5/7

The standard equation of a line is given by, y = mx+c

Finding c, put x = 3 and y = -4

-4 = 5/7×3+c

-4-15/7 = c

c = -43/7

Putting c = -43/7 in equation y = mx+c

y = 5x/7-43/7

or, 7y = 5x-43

Hence, we get the equation of the line, 7y = 5x-43

The perimeter of a polygon is given by the sum of all the lengths of the outside edges of the polygon.

For this problem, the outside edges are given as follows:

Danielle's mistake is that she did not consider two outside edges, one of length 6x - 4 and the other of length 12x + 3. Considering all the edges, the perimeter is given by:

P = 2(6x - 4) + 2(12x + 3) + 14x + 13

P = 12x - 8 + 24x + 6 + 14x + 13

In polar coordinates, the radial distance "r" is defined as the distance from the origin to a point in the plane. Since distance cannot be negative, we only consider the positive square root of 3 in the range for this problem. So, the correct range for "r" is 0 ≤ r ≤ √3, and negative square root of 3 is not included because it doesn't represent a valid distance in polar coordinates.

To find the volume of the given solid enclosed by the hyperboloid −x2 − y2 + z2 = 6 and the plane z = 3 using polar coordinates, we need to express the equation of the hyperboloid in terms of polar coordinates.

Substituting x = rcosθ and y = rsinθ, we get:

−r2cos2θ − r2sin2θ + z2 = 6

Simplifying, we get:

z2 = 6 - r2

Since the plane z = 3 intersects the hyperboloid, we have:

3 = √(6 - r2)

Solving for r, we get:

r = √3

Hence, the range for r is 0 ≤ r ≤ √3.

In summary, the negative square root of 3 is not included in the range of r because r represents a distance and cannot be negative. The volume of the solid can be found by integrating the function f(r,θ) = √(6 - r2) over the range 0 ≤ r ≤ √3 and 0 ≤ θ ≤ 2π using polar coordinates. The result will be in cubic units and can be obtained by evaluating the integral.

The values of the given trigonometric ratios are:

cos (2x) = -16/25

tan (2x) =  -3/2

There are three main trigonometric ratios which are:

sin x = opposite/hypotenuse

cos x = adjacent/hypotenuse

tan x = opposite/adjacent

We are given that:

cot (x) = 3/4

We know that cot(x) = 1/tan x

Thus:

tan x = 4/3

Thus, using the knowledge of Pythagoras theorem:

sin x = 4/5

cos x = 3/5

Thus:

sin (2x) = 2 sin x cos x

= 2 * (4/5) * (3/5) = 24/25

Similarly:

cos (2x) = cos²x - sin²x

= (3/5)² - (4/5)²
