The value of x for the similar triangles is 57.5 units.

The value of x is determined by applying the principle of similar triangles as shown below.

In the given diagram, we can assume the following for the similar triangles;

length 46 is congruent to length (16 + 46)

length 20 + x is congruent to length x

So we will have the following equation;

46/x = (16 + 46 ) / ( 20 + x )

46/x = ( 62 ) / ( 20 + x )

46 ( 20 + x ) = 62x

920 + 46x = 62x

920 = 16x

x = 920 / 16

x = 57.5

The height (in inches) of a triangle with an area of 720 square inches and base of 32 inches is 45 inches.

The height of a triangle can be found using the formula for the area of a triangle: A = (1/2)bh, where A is the area, b is the base, and h is the height.

In this case, we are given the area (720 square inches) and the base (32 inches) and are asked to find the height.

First, we can plug in the given values into the formula:

720 = (1/2)(32)(h)

Next, we can simplify the equation by multiplying both sides by 2:

1440 = 32h

Finally, we can solve for the height by dividing both sides by 32:

h = 45 inches

Therefore, the height of the triangle is 45 inches.

Looking at the table, we can see that the addends follow a pattern where each subsequent pair of addends adds up to 1/5. Specifically, the missing addend is 2/5 - 3/10, which equals 1/10. The missing sums are 1/2 and 4/10.

The addends in the table are as follows:

1/10 + 1/5 = 3/10, 1/5 + 1/5 = 2/5

3/10 + 1/5 = 1/2

We can observe that the first two pairs of addends add up to 1/5 less than the subsequent sums. This pattern indicates that the missing addend must be

1/5 - 1/10 = 1/10

which would make the third pair of addends add up to

1/2 - 1/10 = 4/10

Therefore, the missing sums are 1/2 and 4/10, respectively. This pattern can be helpful in solving similar problems where pairs of addends add up to a specific sum or difference.

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

Answer:

14.75 + 18.75x ≤ 425

Step-by-step explanation:

Total amount they have is $425

Parking for the entire group = $14.75

If x is the number of persons in the group, the cost of x tickets at $18.75 per head
= 18.75x

The total cost incurred
= Parking Cost + Ticket Cost

= 14.75 + 18.75x

This has to be less than equal to 425

So the inequality is

14.75 + 18.75x ≤ 425

Using the given functions, the product of (g*f)(x) is 2x³ - 11x² + 12x + 9.

A relation between a set of inputs having one output each is called a function. The product of (g*f)(x) can be found by multiplying the functions f(x) and g(x) together.

Since f(x) = 2x² - 5x - 3 and g(x) = x - 3, then the product of (g*f)(x) can be solved as follows:

(g*f)(x) = g(x)*f(x) = (x - 3)(2x² - 5x - 3)

Use the distributive property:

(g*f)(x) = 2x³ - 5x² - 3x - 6x² + 15x + 9 = 2x³ - 11x² + 12x + 9.

Therefore, the correct answer is 2x³ - 11x² + 12x + 9.

The monthly revenue for the route, R, as a function of the ticket price, x, can be expressed as R(x) = (9000 + 50(150 - x))x.

The airline carries 9000 passengers per month, and each pays $150, so the initial monthly revenue is R(150) = 9000 x $150 = $1,350,000.

If the ticket price is decreased by $1, the airline will gain 50 passengers, so the new monthly revenue can be calculated by adding the revenue gained from these additional passengers to the initial revenue, and subtracting the revenue lost from the decrease in ticket price. The revenue gained from the additional passengers is 50(x - $150), since each passenger pays the new ticket price x instead of $150. The revenue lost from the decrease in ticket price is 9000($150 - x), since each of the 9000 passengers pays $150 - x instead of the initial price of $150.

Putting these together, we get:

[tex]R(x) = R(150) + 50(x - $150) - 9000($150 - x)[/tex]

R(x) = (9000 x $150) + 50x - 50($150) - 9000($150) + 9000x[tex]R(x) = R(150) + 50(x - $150) - 9000($150 - x)[/tex]

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}.

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.

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.

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.

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.
