Based on the derivative, a function can cross the x-axis a certain number of times depending on the number of times the derivative changes sign.

A derivative is a mathematical tool that measures the rate of change of a function at a specific point. Specifically, it is the slope of the tangent line to the function at that point. The derivative can be used to determine where a function is increasing, decreasing, or reaching a maximum or minimum value.
When a function crosses the x-axis, it means that the y-value of the function is equal to zero. In order for a function to cross the x-axis, it must change sign from positive to negative or vice versa. This happens when the function passes through a maximum or minimum point.
If the derivative of the function is positive at a point, it means that the function is increasing at that point. If the derivative is negative, the function is decreasing. If the derivative is zero, it means that the function is neither increasing nor decreasing, and it could be at a maximum or minimum point.
Therefore, the number of times a function can cross the x-axis depends on the number of times the derivative changes sign. If the derivative changes sign twice, the function can cross the x-axis twice. However, if the derivative changes sign an odd number of times, the function can only cross the x-axis once.

Angle-Angle (AA) similarity postulate,  if two angles of one triangle are congruent to two angles of another, then the triangles are similar.

Similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other. Similar triangles look the same but the sizes can be different.

As per the diagram,

Triangles RPQ & RST are similar since

∠P = ∠S & ∠Q = ∠T

Side - side - side (SSS) similarity theorem - If the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.

#3, the one with the straight line --> linear bc its a constant slope

The unit tangent vector t(1) at t = 1 is:

t(1) = (4 i + 6 j + 3 k) /\(\sqrt{(61)}\)

To find the unit tangent vector,

we need to calculate the derivative of the position vector r(t) with respect to the parameter t, and then normalize the resulting vector.

Given the position vector r(t) = 4t i + 3t^2 j + 3t k,

we can find the derivative:

r'(t) = d(r(t))/dt

     = 4 i + 6t j + 3 k

Now, we can evaluate r'(t) at t = 1:

r'(1) = 4 i + 6(1) j + 3 k

      = 4 i + 6 j + 3 k

To obtain the unit tangent vector,

we need to normalize r'(1):

t(1) = r'(1) / ||r'(1)||

where ||r'(1)|| represents the magnitude or length of r'(1).

The magnitude of r'(1) is given by:

||r'(1)|| = \(\sqrt{((4^2) + (6^2) + (3^2))}\)

       = \(\sqrt{61}\))

This is the normalized vector representing the direction of the tangent to the curve at the point where t = 1.

g(x) = (x+2-3) + 4 = (x-1)+4

Answer:

\(y = \frac{5}{4}x\)

Step-by-step explanation:

1. The slope-intercept form of a linear equation is y = mx + b! Y is the y-coordinate, is the slope, x is the x-coordinate, and b is the y-intercept.

2. To find the slope, let's take any two points from the line, such as (0,0) and (400,500), and plug their values into this formula: \(\frac{y_2-y_1}{x_2-x_1}\)

3. The slope is 5/4, so the equations looks like this so far: \(y=\frac{5}{4}x + 0\)

4. Because b is the y-intercept, b = 0 because the line intersects with the y-axis at (0,0).

5. Now that we have our slope (5/4) and y-intercept (0), we plug in those values to the slope-intercept form and get the equation of: \(y= \frac{5}{4}x\)

Answer:

I believe it is x^2-9

Step-by-step explanation:

Since we don't have a specific "number" you use x. It says it's squared to put an exponent of 2. It also says that 9 is subtracted by it so put -9.

The values of x, RM, RT, and MT are 15, 84, 168, and 84 respectively.

simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

Given a system of equations Where RM = 5x + 9 and MT = 8x - 36.

Since,

M is the midpoint of RT

Thus,

RM = MT

5x + 9 = 8x - 36

3x = 45

x = 15

So,

1) RM = 5x + 9

RM = 75 + 9 = 84

2) MT = 8x -36

MT = 120 - 36 = 84

3) RT = RM + MT

RT = 84 +84 = 168

Therefore, The values of x, RM, RT, and MT are 15, 84, 168, and 84 respectively.

A) add the two elevations together:

6900 + 8100 = 15,000 meters.

B) Divide the total distance by 2:

15,000 / 2 = 7,500 meters.

Because the distance to the halfway point is larger than the elevation of Ojos del Salado, the elevation would be below seal level.

C Add the halfway point from part B to the lowest elevation:

Part 1: Kate should buy 100 coats to maximize profits.Part 2: The probability that the coats sell out is 0.25 (25%), and the probability that they do not sell out is 0.75 (75%).

To maximize profits, Kate should consider the scenario where she sells all the coats without any left over at the end of the season.

Since the sales are uniformly distributed between 100 and 400, buying 100 coats ensures that she meets the minimum expected sales of 100. Purchasing more than 100 coats would increase costs without a guarantee of higher sales, potentially leading to excess inventory and lower profits.

Given that the sales are uniformly distributed between 100 and 400 coats, Kate's purchase of 100 coats covers the minimum expected sales.

The probability of selling out can be calculated by finding the proportion of the range covered by the desired sales (100 out of 300). Therefore, the probability of selling out is 100/300 = 0.25 or 25%. The probability of not selling out is the complement, which is 1 - 0.25 = 0.75 or 75%.

Answer:-55

Step-by-step explanation:

-11 times 5= -55

The number of adult tickets sold more than the children's tickets are 65.

It is given in the question that the charge of an adult ticket and a children's ticket is $8 and $6 respectively.

It is also given that, on a certain day the number of tickets sold are 255 at a total cost of $1,850.

We have to find the number by which children's ticket were sold more than adult tickets.

Let the number of children tickets sold on that particular day be x.

Let the number of adult tickets sold on that particular day be y.

Hence, according to the question,

x + y = 255  ...(1)

Also,

6*x + 8*y = 1850

Dividing 2 from both sides, we get

3x + 4y = 925  ...(2)

Multiplying (1) by 3, we get

3x + 3y = 765  ...(3)

(2) - (3)

(3x - 3x) + (4y - 3y) = 925 - 765

0 + y = 160

y = 160

Hence, the number of adult tickets sold are 160.

We know that,

x + y = 255

Hence,

x + 160 = 255

x = 255 - 160

x = 95

Hence, the number of children's tickets sold are 95.

The number of adult tickets sold more than the children's ticket are =

160 - 95 = 65 tickets.

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

Here, we have

Given: 3a - 5b = -26, a + 2b = 6

We have to solve this equation.

3a - 5b = -26...(1)

a + 2b = 6...(2)

Now we multiply equation (1) by 2 and equation (2) by 5 and we get

6a - 10b = -52....(3)

5a + 10b = 30....(4)

After solving equations (3) and (4), we get

11a = -22

a = -2

Now we put the value of 'a' in equation(3) and we get

6(-2) - 10b = -52

-10b = -52 + 12

-10b =  -30

b = 3

Hence, the value of a = -2 and b = 3.

The value of f[g(x)] is - 64x³ - 336x² - 588x - 340 and the value of g[f(x)] is -4x³ + 19

The functions are as follows; f(x) = -x³ +3 and g(x) = 4x+7

The value of f[g(x)] is obtained by replacing every x in f(x) with the value of g(x) as given below

f[g(x)] = f(4x + 7) = - (4x + 7)³ + 3

When we expand (4x + 7)³, it gives us 64x³ + 336x² + 588x + 343

Then

f[g(x)] = - 64x³ - 336x² - 588x - 340

Similarly, g[f(x)] is obtained by replacing every x in g(x) with the value of f(x) as shown below;

g[f(x)] = g(-x³ + 3) = 4(-x³ + 3) + 7g

[f(x)] = -4x³ + 19

Therefore,

f[g(x)] = - 64x³ - 336x² - 588x - 340

g[f(x)] = -4x³ + 19
