Answer:

The system of equations as described:

y = (-3/4)x + 3

y = -12

Combining two equations, we have:

=> -12 = (-3/4)x + 3

=> -15 = (-3/4)x

=> x = -15 x (-4/3) = 20

=> Solution is (20, -12)

=> Option A is correct.

Hope this helps!

:)

Step By Step:

The equations given to us are:

y = (-3/4)x + 3

y = -12

Now that we have y we can change that to -12

-12 = (-3/4)x + 3

-15 = (-3/4)x

x = -15 x (-4/3) = 20

This would give us (20, -12)

Those are the only one I know, sorry :/

The range of f(x) = 3x + 9 is: {y|All real numbers}

The equation of the function is given as:

f(x) = 3x + 9

The above function is a linear function, and the range of a linear function is the set of all real numbers

Hence, the range of f(x) = 3x + 9 is: {y|All real numbers}

Answer: A. 330 m/s

Just took a test on it

Answer: A

Step-by-step explanation:

Upon calculating the volume of the given cylinder and comparing it with each option, it is determined that none of the provided cylinders have the same volume as the cylinder with a height of 32 meters and a diameter of 20 meters.

The question is asking which cylinders have the same volume as a cylinder with a height of 32 meters and a diameter of 20 meters. To find this out, we first calculate the volume of the given cylinder. The formula for the volume of a cylinder is[tex]V = \(\pi r^2h\)[/tex], where V is the volume, [tex]\(r\) i[/tex]s the radius of the base, and h is the height of the cylinder. In this case, the radius (half of the diameter) is 10 meters, so the volume is:

[tex]V = \(\pi (10)^2 \times 32\) = 320\(\pi\) cubic meters.[/tex]

Now, let's check each option:

Therefore, none of the provided options have the same volume as the given cylinder.

The cylinders with heights and diameters of 16 meters and 40 meters, and 128 meters and 10 meters, respectively, have the same volume as the given cylinder.

To find cylinders with the same volume as the given cylinder (height = 32m, diameter = 20m), we calculate its volume and compare it with the volumes of the listed cylinders. Cylinders with heights and diameters of 16 meters and 40 meters, and 128 meters and 10 meters, have the same volume as the given cylinder.

The question involves finding which cylinders have the same volume as a cylinder with a height of 32 meters and a diameter of 20 meters. To solve this, we first calculate the volume of the given cylinder using the formula for the volume of a cylinder, V = πr²h, where r is the radius (half of the diameter) and h is the height.

The volume of the given cylinder is V = π(10²)(32) = 320π cubic meters. We then apply the same formula to each of the listed cylinders, converting dimensions to the same units where necessary, to identify which ones have the same volume.

Therefore, the cylinders with heights and diameters of 16 meters and 40 meters, and 128 meters and 10 meters, respectively, have the same volume as the given cylinder.

Answer:

x= 3, y= -1

Step-by-step explanation:

Let's solve your system by substitution.

2x−5y=11 and −2x+3y=−9

Solve x in 2x-5y=11

2x-5y=11 (add 5y to both sides)

2x = 5y + 11 (divide 2 by both sides)

x=5/2y + 11/2

substitute 5/2y+11/2 for x in -2x+3y=-9

-2x+3y=9

-2 (5/2y+11/2)+3y=-9

-2y-11=-9 (simplify both sides)

-2y-11=-9 (add 11 to both sides)

-2y=2 (divide both sides by -2)

y=-1

substitute your y (-1) in x = 5/2y + 11/2

x = 5/2y + 11/2

x=5/2(-1)+11/2

x=3

therefore, y= -1 and x = 3

C. The set of all points in a plane for which the sum of the distances

to two fixed points equals a certain constant is the best definition.

An ellipse is a curve formed by a plane, that intersects a cone at an angle with respect to the base. It is a curve surrounded by two focal points. Ellipse is a locus of points, the sum of whose distances from two foci is constant.

An ellipse is a circle that has been stretched in one direction, to give it the shape of an ova

An ellipse has an eccentricity less than one, and it represents the locus of points, the sum of whose distances from the two foci of the ellipse is a constant value. A simple example of the ellipse in our daily life is the shape of an egg in a two-dimensional form and the running tracking in a sports stadium.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity

An ellipse has a simple algebraic solution for its area, but only approximations for its perimeter (also known as circumference), for which integration is required to obtain an exact solution.

The standard equation for an ellipse, x 2 / a 2 + y2 / b 2 = 1, represents an ellipse centered at the origin and with axes lying along the coordinate axes. In general, an ellipse may be centered at any point, or have axes not parallel to the coordinate axes.

Answer:

Step-by-step explanation:

Answer: Is true sometimes.

Step-by-step explanation:

I guess that here we have two matrices, A and B, that are nxn.

We can see that if those matrices can conmutate, then we can try it with some simple matrices.

[tex]A = \left[\begin{array}{ccc}1&0\\0&-1\end{array}\right] . B = \left[\begin{array}{ccc}2&0\\1&1\end{array}\right][/tex]

Here, we would have that:

[tex]AB = \left[\begin{array}{ccc}2&0\\-1&-1\end{array}\right][/tex]

[tex]BA = \left[\begin{array}{ccc}2&0\\1&-1\end{array}\right][/tex]

You can see that AB and BA are different, then the statement is not always true.

But it is true sometimes, if A or B are the identiti, then I*A = A*I, in this case would be true.

It is also true if A and B are diagonal matrices, let's prove it:

[tex]A = \left[\begin{array}{ccc}a&0\\0&b\end{array}\right] , B = \left[\begin{array}{ccc}c&0\\0&d\end{array}\right][/tex]

[tex]AB = \left[\begin{array}{ccc}ac&0\\0&bd\end{array}\right] = BA[/tex]

Answer:

(-5, -2)

Step-by-step explanation:

3x+4y=-23

x=3y+1

since we have what x is, we need to subsitute

3( 3y+1) + 4y= -23

no we need to multiply the number inside the parenthesis by 3

9y + 3 + 4y= -23

combine like terms ( add the numbers or variables that look alike)

9y+4y is 13y

13y+3= -23

since we need to get the y alone we need to subtract 3 on both sides since its the opposite of adding

13y+3-3=-23-3

13y= -26

now we divide 13 on both sides to get Y alone

13y/13= -26/13

y= -2

now since we have y we need to substitute it to find x

x= 3y+1

x= 3( -2) +1

now we mutliply 3 with -2

x= -6 +1

x=-5

y= -2

Answer: About 2.875 times more than a hummingbird

Step-by-step explanation: The way you can solve this problem is just by dividing 82,800 by 28,800. If you want to check your work multiply 28,800 and 2.875.

A bee flaps its wings approximately 3 times faster than a hummingbird.

Bee: 82,800 times/hour ≈ 8.3 × 10^4 times/hour

Hummingbird: 28,800 times/hour ≈ 2.9 × 10^4 times/hour

Now, let's compare the two estimates:

8.3 × 10^4 (bee) is approximately 3 times faster than 2.9 × 10^4 (hummingbird).

So, a bee flaps its wings about 3 times faster than a hummingbird.
