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.

Answer:

Step-by-step explanation:

We separate into 2 congruent triangles. Both have a base of 3.5 and a height of 9 inches. Using pythagoran theorum, we will square 9 and 3.5

81 and 12.25

Add them up and it's 93.25

[tex]\sqrt{93.25}[/tex]=9.65660395791

Now since it's isosceles, the other side will also be 9.65660395791.

9.65660395791 + 9.65660395791 + 7 =26.3132079158

You want it rounded to the nearest tenth, so 26.3

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]

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

Thus, the monthly revenue for the route, R, as a function of the ticket price, x, is [tex]R(x) = (9000 + 50(150 - x))x[/tex]

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.

Answer:

The difference between the LCM and the GCF of 30 and 55 are that the LCM is the smallest positive integer that is divisible and the GCF is the largest positive integer that divides each of the integers.

Step-by-step explanation:

The intersection point on the graph has an approximate x-value of 1a.

Making the curve that represents a function on a coordinate plane is the process of graphing a function. If the curve (or graph) represents the function, then each point on the curve will satisfy the function equation.

The line, also called the "curve," has a point at each point that fulfils the function.

The three lines are contemporaneous if they all cross at the same point.

From the second equation,

x = 8y + 19

Putting value of x,

2(8y + 19) + 3y = 0                              9(8y + 19) + 5y = 17

16y + 38 + 3y = 0                                 72y + 171 + 5y = 17

19y = -38                                                77y = -154

 y = -2                                                      y = -2

You'll see that the y value for the answer is the same for the two equations. Simply evaluate the second equation now to find x. Hence, we are aware that the y-coordinate is negative two at some x number.

x = 8(-2) + 19

x = -16 + 19

x = 3

The single point that these three equations share is (3, -2).

4x - 3y = 13                     eq1

-6x + 2y = -7                   eq2

Use the elimination method. Multiply eq1 by eq2 and multiply eq2 by eq3.

8x - 6y = 26                eq1

-18 + 6y = -21              eq2

Adding the equations to eliminate the y terms.

-10x = 5

 x = -1/2

Substituting this value of x into any of the equations to solve for the value of y.

Substituting the first equation into the second equation. In terms of x, this will translate the second equation. From that freshly created equation, find x. Once you solved for x, substitute that value of x into the first equation to solve for y.

You have a vertical line that passes all points that have the x coordinate 7 and you have a horizontal line that passes all point that have the y coordinate -5.

If you were to graph these two lines, they will be intersecting at (7, -5).

Now, draw the following lines on a coordinate system:

i) A vertical line passing through the points (3, 0).

ii) A horizontal line passing through the point (0, 6).

iii) A line passing through the points (0,0) and (1, -3).

Once you have drawn these lines, look for 3 points of intersection.

Area = (base × height) / 2

Lines that have the same slope never intersect.  Put both equations in y=mx+b  form where the slope is the coefficient of x.

2x + 3y = > 3y = -2x + 23

y = (-2 / 3) x + 23/3

7x + py = 8

py = -7x + 8

y = (-7 / p) x + 8/p

Set the slopes equal to each other.

-2 / 3 = -7 / p

Cross-multiply.

-2p = -21

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.

The empirical norm therefore states that 68% of 7-year-old kids are between 47 and 51 inches tall.

A column in a table is a collection of cells which are arranged vertically. A field, like the received field, is a sort of element that contains only one item of data. A column in a table usually contains the values for just a single field.

The empirical rule states that in a normal distribution, 68% of the data fall within one average standard deviation. In this instance, the mean difference is 2 inches, while the average height of 7-year-old kids is 49 inches.

We must identify the range among heights that is within one average standard deviation in order to apply the scientific rule. To accomplish this, we can add and subtract the standard variance from the median as follows:

Mean ± (Standard Deviation) = 49 ± 2

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.
