Is the volume of the resulting sugar mixture equal, more than or less than the sum (20 mL sugar +50mL water ) of the volumes of the unmixed sugar and water?

Answer:

It is not clear what you mean by "pre-image" in this context. However, based on the given information, we can say that the second triangle is a dilation of the first triangle.

A dilation is a transformation that changes the size of an object, but not its shape. In this case, the second triangle has the same shape as the first triangle, but its sides are scaled up by a factor of 8/3, which is greater than 1. Therefore, the second triangle is an enlargement (or a magnification) of the first triangle.

Answer: Your welcome!

Step-by-step explanation:

The transformation of the triangle is a reduction. This is because the side of the triangle that was 3 cm has been reduced to 8 cm, while the other two sides have stayed the same. This reduction has resulted in the triangle being smaller than the original triangle.

All the roots of all the polynomials in {f1, ..., fn}.

(a) Let E be an intermediate field of the extension K⊂F and assume that E=K(u1,…,ur) where the ui are (some of the) roots of fεK [x]. Then F is a splitting field of f over K if and only if F is a splitting field of f over E.

(b) We can extend part (a) to splitting fields of arbitrary sets of polynomials by first noting that the field E must contain the coefficients of all the polynomials in the given set. This implies that for a given set of polynomials {f1, ..., fn}, the field F is a splitting field over K if and only if it is a splitting field over E, where E is the smallest field containing the coefficients of {f1, ..., fn}. In other words, F must contain all the roots of all the polynomials in {f1, ..., fn}.

Answer:

We can use the properties of logarithms to simplify this expression:

log2(9x^10/y²) = log2(9) + log2(x^10) - log2(y²)

Now we can apply the power rule of logarithms to the second term:

log2(x^10) = 10 log2(x)

Substituting back into the original expression:

log2(9x^10/y²) = log2(9) + 10 log2(x) - log2(y²)

This is the simplified form of the expression.

The inverse of f(x)=−8x+9 is y = (-x + 9)/8.

The inverse of a function is found by switching the x and y variables and solving for y. This is done to find the function that will undo the original function.

To find the inverse of f(x)=−8x+9, we will follow these steps:

1. Switch the x and y variables: x = -8y + 9
2. Solve for y by isolating the y variable on one side of the equation:
x - 9 = -8y
(x - 9)/-8 = y
3. Simplify the equation by dividing the numerator and denominator by -1:
y = (-x + 9)/8

Therefore, the inverse of f(x)=−8x+9 is y = (-x + 9)/8.

Note that we do not need to use parentheses around the denominator since it is a single term. We also do not need to use the term "inverse" in our answer since we are simply finding the inverse of the function. The terms "denominator" and "parentheses" are also not needed in our answer since they do not apply to this specific problem.

Answer:

  27 cm

Step-by-step explanation:

You want the distance from the vertex of an ellipse to the opposite focus if the semi-major axis is 15 cm, and the minor axis is 18 cm.

The square of the distance from the center to either focus is the difference of the squares of the semi-axes. The semi-minor axis is half the  diameter of the ellipsoid.

  c² = 15² -(18/2)² = 225 -81 = 144

  c = √144 = 12 . . . . . cm

The distance from the vertex (V) to the opposite focus is the distance from vertex to center plus the distance from center to focus:

  15 cm +12 cm = 27 cm

The kidney stone should be located 27 cm from the vertex for greatest effect.

Taking into account the definition of molarity, the mass of MgBr₂ in 215 mL of a 0.350 M solution of MgBr₂ is 13.85 grams.

Molarity is a measure of the concentration of a solution expressed in the number of moles dissolved per liter of solution.

This is, the molarity indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

molarity= number of moles of solute÷ volume

Molarity is expressed in units moles/L.

The molar mass of substance is a property defined as the amount of mass that a substance contains in one mole.

In this case, you have:

Replacing in the definition of molarity:

0.350 M= number of moles of solute÷ 0.215 L

Solving:

0.350 M× 0.215 L= number of moles of solute

0.07525 moles= number of moles of solute

Being the molar mass of MgBr₂ 184.11 g/mole, the mass of the compound is calculated as:

mass of MgBr₂= 0.07525 moles× 184.11 g/mole

mass of MgBr₂= 13.85 grams

For 175÷2, the quotient is 87 and remainder is 1

When dividing 175 by 2, we can use long division to find the quotient and remainder.

First, we will divide 2 into the first digit, 1. Since 2 does not go into 1, we will move to the next digit, 7. 2 goes into 7 three times, so we will write 3 above the 7.

Next, we will multiply 3 by 2 to get 6, and subtract this from 7 to get a remainder of 1.

We will then bring down the next digit, 5, and divide 2 into 15. 2 goes into 15 seven times, so we will write 7 above the 5.

Finally, we will multiply 7 by 2 to get 14, and subtract this from 15 to get a remainder of 1.

Therefore, the quotient is 87 and the remainder is 1.

The intersection point of ℓ and Q is (1, 1, 2.5) is not in any of the option.

To find the intersection point of ℓ and Q, we need to find a point that lies on both the line and the plane. We can do this by finding the equation of the line and the equation of the plane, and then solving for the point where they intersect.

First, let's find the equation of the line ℓ. We can use the formula for a line passing through two points:

(x - x1) / (x2 - x1) = (y - y1) / (y2 - y1) = (z - z1) / (z2 - z1)

Plugging in the points (1, 1, 1) and (2, 0, 1), we get:

(x - 1) / (2 - 1) = (y - 1) / (0 - 1) = (z - 1) / (1 - 1)

Simplifying, we get:

x - 1 = -y + 1 = 0

So the equation of the line is x + y = 2.

Next, let's find the equation of the plane Q. We can use the formula for a plane passing through three points:

| x - x1  y - y1  z - z1 |
| x2 - x1  y2 - y1  z2 - z1 | = 0
| x3 - x1  y3 - y1  z3 - z1 |

Plugging in the points (0, 0, 0), (1, 2, 2), and (1, 0, 1), we get:

| x   y   z |
| 1   2   2 | = 0
| 1   0   1 |

Expanding the determinant, we get:

x(2 - 0) - y(2 - 1) + z(0 - 2) = 0

Simplifying, we get:

2x - y - 2z = 0

So the equation of the plane is 2x - y - 2z = 0.

Now we can solve for the intersection point of the line and the plane by substituting the equation of the line into the equation of the plane:

2(x + y) - y - 2z = 0

2x + 2y - y - 2z = 0

2x + y - 2z = 0

Since x + y = 2, we can substitute 2 for x + y:

2(2) + y - 2z = 0

4 + y - 2z = 0

y - 2z = -4

Now we can solve for y in terms of z:

y = 2z - 4

And substitute this back into the equation of the line:

x + (2z - 4) = 2

x = 2 - 2z + 4

x = 6 - 2z

Now we have two equations with two unknowns:

y = 2z - 4
x = 6 - 2z

We can solve for z by setting the two equations equal to each other:

2z - 4 = 6 - 2z

4z = 10

z = 2.5

And then solve for x and y:

y = 2(2.5) - 4 = 1
x = 6 - 2(2.5) = 1

So the intersection point of ℓ and Q is (1, 1, 2.5).

Therefore , the solution of the given problem of function comes out to be Nolan dropped the ball from a height of 12 units at the beginning.

The study of mathematics includes numbers, symbols, and their parts, as well as anatomy, building, and both actual and hypothetical geographic locations. The relationships between different components, each of which has a corresponding result, are described by a function. A function is made up of a variable of distinct components that, when put together, produce specific results for each input.

Here,

Assume that h represents the original height at which Nolan threw the ball. The object bounces once and rises to a height of 4, so after the bounce it has a height of h + 4.

=> h = k f(1) (1)

where k is a constant that denotes how much energy the object retains after each bounce.

=> h = k(4) (4)

The knowledge that the ball returns to a height of 4 on the first bounce must be used to determine the value of k:

=> 4 = k f(1) (1)

=> 4 = k (4/3)

=> k = 3

When we put this number of k back into the equation as a replacement for h, we get:

=> h = k(4) = 3(4) = 12
