Answer:

Step-by-step explanation:

The correct application of the quotient rule is  f'(x) = [(3x - 2)2x - (x²+5)(3)]/[(3x - 2)]²

The derivative of a function f'(x) is the rate of change of the function with respect to a variable.

Since we have f(x) = (x²+5)/(3x-2), to find its derivative f'(x), we use the quotient rule.

Given a function f(x) = u(x)/v(x) then the derivative of f(x) which is f'(x) = [v(x)du(x)/dx - u(x)dv(x)/dx]/[v(x)]²

So, with f(x) = (x²+5)/(3x-2)

u(x) = (x²+5) and v(x) = (3x-2)

So, du(x)/dx = d(x²+5)/dx

= d(x²+5)/d(x²+5) × d(x²+5)/dx

= 2x

and

dv(x)/dx = d(3x - 2)/dx

= d3x/dx - d2dx

= 3 - 0

= 3

Since  f'(x) = [v(x)du(x)/dx - u(x)dv(x)/dx]/[v(x)]², substituting the values of the variables into the equation, we have that

f'(x) = [v(x)du(x)/dx - u(x)dv(x)/dx]/[v(x)]²

f'(x) = [(3x - 2)2x - (x²+5)(3)]/[(3x - 2)]²

So, the quotient rule is  f'(x) = [(3x - 2)2x - (x²+5)(3)]/[(3x - 2)]²

The speed rate at which the aircraft is gaining altitude is;

dx/dt = 250 miles per hour

Since the aircraft is climbing at 30° to the horizontal. it means there will be a vertical component which will be the altitude and also a horizontal component which will be the horizontal distance covered. while the hypotenuse will be how far it has climbed.

Let us call the vertical component x and the hypotenuse component z.

Thus, from trigonometric ratios, we can say that;

sin 30 = x/z

We are looking for how fast the aircraft is gaining altitude. Thus, using Liebniz notation, we can say this rate is; dx/dt. Thus;

sin 30 = (dx/dt)/(dz/dt)

0.5 = (dx/dt)/(dz/dt)

0.5 × (dz/dt) = dx/dt

Its' speed is 500 mph. This means dz/dt = 500

Thus;

dx/dt = 0.5 × 500

dx/dt = 250 mph

Hence, the speed rate at which the aircraft is gaining altitude is;

dx/dt = 250 miles per hour

Step-by-step explanation:

Answer:

a) TPR

b) NM

c) x=6

Step-by-step explanation:

a) since the angle K is the middle letter on in the first triangle, the second triangle's middle letter will be P since they correspond

b) TR is congruent to NM because if you flipped TR upside down, it would match directly with NM

c) 4x-3=21

4x=24

x=6

this is because TR and NM are congruent, so 4x-3 is equal to 21

Answer:

Step-by-step explanation:

To graph the equation y-2=2/3(x+4), you can follow these steps:

Begin by isolating the y term on one side of the equation. To do this, you can add 2 to both sides of the equation:

y-2+2=2/3(x+4)+2

y=2/3(x+4)+2

Next, you can simplify the right side of the equation by multiplying 2/3 by (x+4):

y=2/3(x+4)+2

y=(2/3)x+(2/3)4+2

y=(2/3)x+8/3+2

y=(2/3)x+14/3

This is the standard form of the equation y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is m=2/3 and the y-intercept is b=14/3.

To graph the equation, you can use the slope and y-intercept to plot the first point on the graph. The y-intercept is the point where the graph crosses the y-axis, so you can plot the point (0,14/3) on the graph.

From this point, you can use the slope to find the next point on the graph. The slope is the change in y over the change in x, so you can use the slope to find the change in y and the change in x between two points on the graph. For example, you could choose a point that is 1 unit to the right of the y-intercept, or (1,0). The change in y between these two points is (14/3)-0=14/3 and the change in x is 1-0=1. Using the slope, you can find the y-coordinate of the next point on the graph:

y2=y1+m(x2-x1)

y2=14/3+2/3(1-0)

y2=14/3+2/3

y2=20/3

You can repeat this process to plot additional points on the graph. For example, you could choose a point that is 2 units to the right of the y-intercept

The minimum number of people that would need to be at the party to guarantee that at least three people share the same birth date, birth month, and birth year is Three (3).

To find the number of people that would need to be at the party to guarantee that at least three people share the same birth date, birth month, and birth year, we need to consider the number of possible birthdays that exist within the given age range (18 to 24 inclusive).

There are 12 months in a year, and each month has between 28 and 31 days (depending on the month). Therefore, there are a total of 12 * 31 = 372 possible birthdays within a given year.

There are 7 possible birth years within the given age range (18 to 24 inclusive), which means there are a total of 7 * 372 = 2596 possible birthdays within the given age range.

Since we want to guarantee that at least three people share the same birthday, we need at least 3 people to be at the party.

Answer:

length is 4 units

width is 2 units

Perimeter is 12 units

Area is 8 sq units

Step-by-step explanation:

Since you have a graph of the points, you can see the shape is a rectangle. Count to find the measure of the length and width.

Perimeter is the distance all the way around the shape.

length + width + length + width

Area is

length × width

The slope intercept form of equation of required line is

[tex]y = \frac{2}{3}x - 2[/tex]

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Slope of the required line = [tex]\frac{2}{3}[/tex]

The line passes through (0, -2)

Equation of the required line =

Answer:

Step-by-step explanation:

To find the centroid of a triangle with vertices A, B, and C, we can use the following formula:

centroid = (x1 + x2 + x3) / 3, (y1 + y2 + y3) / 3

where (x1, y1), (x2, y2), and (x3, y3) are the coordinates of the vertices A, B, and C, respectively.

In this case, we have A = (-3, 1), B = (-2, 4), and C = (5, -2), so the centroid of the triangle is:

centroid = ((-3) + (-2) + 5) / 3, (1 + 4 + (-2)) / 3 = (0, 1/3)

Therefore, the coordinates of the centroid of ABC are (0, 1/3).

The probability that 2 of the 9 voters will prefer Candidate A is 0.30033

Given that 25 % of voters prefer candidate A

In this question, we used binomial distribution to find the probability that 2 of the 9 voters will prefer candidate A.

The binomial distribution follows the probability  mass function of:

⁹C₂ * (0.25) ² *  (0.75)⁷ =>

⁹C₂  = (9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1)/ (7 * 6 * 5 * 4 * 3 * 2 * 1) (2 * 1) =>

The equation of the circle for all the given values is obtained as  x² + y² + 8x + 2y + 8 = 0.

The equation for a circle can be written by knowing the coordinates of its centre and the length of its radius.

Since the radius is the distance from the centre to a point on the circle, the equation can be written by distance formula as s (x - h)² + (y - k)² = r² where (h, k) is the coordinate of the centre.

The coordinates of the centre of the circle is given as (-4, -1).

And, the radius is 3.

The general equation of the circle for centre at (h, k) and radius r is given as (x - h)² + (y - k)² = r².

Substitute the corresponding values to obtain,

(x - h)² + (y - k)² = r²

=> (x - (-4))² + (y - (-1))² = 3²

=> (x + 4)² + (y + 1)² = 9

=> x² + 8x + 16 + y² + 2y + 1 = 9

=> x² + y² + 8x + 2y + 8 = 0

Hence, the required equation for the circle is given as  x² + y² + 8x + 2y + 8 = 0.

What is a differentiable function:

A function with a differentiable value of one real variable is one whose domain contains a derivative. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.
