HELP ASAP.Next time, the rabbit from the previous problem started at 10 where on the number line can he be after the same three jumps?

This is the previous problem: A rabbit started at point 0 and made 3 jumps a jump of 4 units then a jump of 2 units and then a jump of 1 unit we do not know the direction of either jump where on the line could the rabbit be.

Answer:y = (5/4)x - 3/2

Step-by-step explanation:

The coordinates of point c on the coordinate plane are (4, 1)

From the question, we have the following parameters that can be used in our computation:

B = (10, 7)

M = (7, 4)

The midpoint formula for two points (x1, y1) and (x2, y2) is:

(x1 + x2) / 2 = x_midpoint

(y1 + y2) / 2 = y_midpoint

So, for points B and C, we have:

x_midpoint = 7

y_midpoint = 4

Also, we have

x_B = 10

y_B = 7

The coordinates of C are calculated as

x_C = 2 * x_midpoint - x_B = 2 * 7 - 10 = 4

y_C = 2 * y_midpoint - y_B = 2 * 4 - 7 = 1

The coordinates of point C are (4, 1).

The lowest score for the normally distribution with mean 72 and standard deviation 8 is equal to 82.

Mean of the normally distributed data 'μ' = 72

Standard deviation 'σ ' = 8

Lowest score with 10% ( 90percentile )

z = InvNorm(0.90)

 = 1.28

Let 'X' be the lowest score for the normal distribution

z = ( X - μ ) / σ

Substitute the values we get,

⇒ 1.28 = ( X - 72 ) / 8

⇒ X - 72 = 1.28 × 8

⇒ X = 10.24 + 72

⇒ X = 82.24

⇒ X = 82 ( round to an integer )

Therefore, the lowest score for normally distribution which will place manage on 90th percentile with given mean and standard deviation is equal to 82.

The linear equation that represents the given literal problem is  3x+12= 28.50 (letter D) and Ava pays $5.5 (letter B)  for each pumpkin.

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=9x+5. Where:

m= the slope.

b= the constant term that represents the y-intercept.

For the given example: m=9 and b=5.

The exercise presents two questions, before solving them, you should convert the given text information into equations.

Data question

     1) Question 1

     Here you should write a linear equation that represents the given problem. Thus, you can write

    3x+12= 28.50

    Since 3x represents the payment of pumpkins and the value 12 is the difference between the total of Ava´s money and the total cost of pumpkins.  

    Therefore, the answer to question 1 is the letter D ( 3x+12= 28.50)

   2) Question 2

As you know the equation that represents the problem, for solving this question you need to find the value of x.

    3x+12= 28.50

     3x=28.5-12

    3x=16.5

      x=16.5/3

      x=5.5 (letter B)

Answer:

y = 4/5 x + 5

Step-by-step explanation:

Slope

Change in y over the change in x

[tex]\frac{1-5}{-5-0}[/tex] = [tex]\frac{-4}{-5}[/tex] = [tex]\frac{4}{5}[/tex]

The slope is [tex]\frac{4}{5}[/tex]

The y-intercept is 5.  It comes from the point (0,5).

Given the problem: Linear equation that passes through the points of (0,5) and (-5,1).

First, whenever you are asked to find a linear equation that passes through two points, remember its going to be slope intercept equation, or y=mx+b. m is the slope, b is the y-intercept.

The y-intercept is where the line crosses the y-axis. The slope can be written as rise/run. Rise and run right is positive, drop and run left is negative.

So in this case, looking at the first point: (0,5), we can see that the y-intercept is 5. Now let's find the slope. We will start at (-5,1) and go to (0,5). Count how many units we rise/drop and how many units we run. Rise 4, run right 5. So the slope is 4/5. Now put all the information into y=mx+b.

Your answer is y=4/5x+5

The equation of the profit function is P(x) = 269x - 4x^2 - 128

The profit function P(x) can be found by subtracting the cost function C(x) from the revenue function R(x), where R(x) = p * x:

So, we have

P(x) = R(x) - C(x)

Substitute the known values in the above equation, so, we have the following representation

P(x) = (285 - 4x) * x - (128 + 16x)

So, we have

P(x) = 285x - 4x^2 - 128 - 16x

Evaluate the like terms

P(x) = 269x - 4x^2 - 128

To find the profit for making and selling 3 million fans, we substitute x = 3 into the profit function P(x):

P(3) = 269(3) - 4(3)^2 - 128

P(3) = 643

For other number of fans, we have

P(5) = 269(5) - 4(5)^2 - 128

P(5) = 1117

P(9) = 269(9) - 4(9)^2 - 128

P(9) = 1969

P(12) = 269(12) - 4(12)^2 - 128

P(12) = 2524

Hence, the profits are 643, 1117, 1969 and 2524

For the first case, we  have the differential  equation governing the height of the water, where the volume of a cone  is  V= 1/3 πr^2h by the similar triangles  we can conclude that  what the  value  will be  for the height, the cone  shape will always have the same relation  with the  radius of the water r/h=8/20⟹r=2/5h⟹r^22=4/25h^2, so V= 4/75πh^3, we will  take the derivative of the  height  of with respect to time t

dV/dt=4/25πh2 dh/dt, now converting into inches  we get  :

dV/dt=−cAh√2gh=−3/5(π(1/6)^2)√64h=−24π/5⋅36 √h=−2π/15√h.

now adding  both the  equations of   dV/dt,

425πh^2dhdt=−2π15√h⟹dhdt=−56h−3/2.

since the tank is empty m  it will happen in at h=0, so for the value of t  we will solve for h(t). after  solving  this differential equation using  the separation of  variables : dh h^3/2=−5/6dt, after  integration of both sides, we get: 25h5/2=−5/6t+C0⟹h5/2=−25/12t+C, since  here the intial height is  20 feet , so h(0)=20, Therefore  20^5/2=−25/12(0)+C⟹C=20^5/2, so h(t)=(−25/12t+20^5/2)^2/5.so  when  h  will be 0 , then −25/12t+20^5/2=0⟺25/12t=205/2⟺t=12/25 20^5/2≃858.65 s=14.31 min.

For the second case, the relationship between the height and radius is different, here the angle between the side of the tank and the vertical is  30 degrees, and the ratio of the radius and height of the tank is √3:1, which is also the ratio of height and radius of the water.  

1/√3=r/h⟹r=h/√3⟹r^2=h^2/3.

V=1/3πr^2h=π/9h^3, to solve it  we need to for dVdt, to  find the height and  rate of  change of height :dV/dt=π/3h^2dhdt here c is 0.6 and Ah=1/9π, dVdt=−35⋅19π⋅8√h, adding up those equations we get dV/dt, we have   π/3h^2dh/dt=−8π/15√h⟹dh/dt=−8/5h^−3/2,  now apply the separation of variables:

h^3/2dh=−8/5dt⟹2/5h^5/2=−8/5t+C, here the initial was at t=0, h is 11, C will be 2/5 11^5/2, therefore h(t)=−8/5t+2/5 11^5/2, so the time when the tank is empty will be  0=−8/5t+2/5 11^5/2⟺85t=25 11^5/2⟺t=1/4 11^5/2= 100.33 s=1.67 min.

The equation of the surface of the sphere is

z = √(100 - (x - 4)² - (y + 3)²). The solution has been obtained by using equation of sphere.

What is a sphere?

A sphere has a round shape and symmetrical arrangement. This three-dimensional solid's surface points are evenly spaced apart from the centre. It has both a volume and a surface area, depending on the radius. It has no faces, corners, or edges.

We know that general form of an equation of sphere is

(x - a)² + (y - b)² + (z - c)² = r²

where a, b, c are the coordinates and r is the radius.

The equation of the sphere is

(x - 4)²+ (y + 3)² + z² = 10²

So, the equation of the bottom hemisphere of sphere is

z = √(100 - (x - 4)² - (y + 3)²)

The height of the vase is 45 inches. To the nearest tenth of an inch, this is 45.0 inches.

A hyperbola is a type of conic section that is the result of intersecting a right circular cone with a plane that is perpendicular to one of its sides, and is oblique to the other. It is defined by two curves that are mirror images of each other and are each a set of all points such that the difference of their distances from two fixed points, called the foci, is a constant value.

A hyperbola can be represented in standard form as an equation, where the x and y terms are squared and the constant terms have opposite signs. It can also be graphed in the coordinate plane, where it appears as a set of two open curves, each going off to infinity in opposite directions.

The height of the vase can be found by using the formula for the height of a hyperbolic paraboloid, which is given by:

h = e × c × √(1 + (2a/c)²)

where h is the height of the vase, e is the eccentricity, a is the width at the narrowest point (4 inches), and c is the average width of the opening and base (6 inches).

Plugging in the values, we get:

h = 2.5 × 6 × sqrt(1 + (2 × 4 / 6)²)

h = 2.5 × 6 × sqrt(1 + (2 × 2)²)

h = 2.5 × 6 × sqrt(1 + 8)

h = 2.5 × 6 × sqrt(9)

h = 2.5 × 6 × 3

h = 45
