Lysera enjoys exploring her land on horseback with its lush green valleys and ancient forests. She can cover a great deal of ground on her horse, Princess Grey Dawn, traveling at 9 km/h. Unfortunately Lysera has allergies. How far would Lysera and Princess Gray Dawn have moved while Lysera’s eyes were shut for 0.50 s during a hard sneeze? (answer in kilometers)

Answers

Answer 1
Answer:

Answer:

0.00125 km.

Step-by-step explanation:

Given,

  • Speed of the horse on which princess travelling, v = 9km/h
  • Time taken by Lysera to sneeze = 0.5 s

As we know

     1 hour = 3600 seconds

=>\ 1\ second\ =\ (1)/(3600)\ hour

=>\ 0.50 second\ =\ (1)/(3600)* 0.50

                             =\ 1.38* 10^(-4)\ hour

So, time taken by Lysera to sneeze can be given by,

t\ =\ 1.38* 10^(-4)\ hour

According to definition of speed,

Speed\ =\ (distance)/(time)

=>distance = speed x time

                  =\ 9\ km/h* 1.38* 10^(-4)\ hour

                  = 0.00125 km

Hence, Princess Gray down will moved by 0.00125 km.

The accompanying summary data on total cholesterol level (mmol/l) was obtained from a sample of Asian postmenopausal women who were vegans and another sample of such women who were omnivores.Diet Sample Size Sample Mean Sample SD
Vegan 85.00 5.20 1.08
Omnivore 91.00 5.65 1.10

Calculate a 99% CI for the difference between the population mean total cholesterol level for vegans and population mean total cholesterol level for omnivores. (Use μvegan−μomnivore). Round to three decimal places.)
Interpret the interval.

a. We are 99% confident that the true average cholesterol level for vegans is less than that of omnivores by an amount within the confidence interval.
b. We are 99% confident that the true average cholesterol level for vegans is greater than that of omnivores by an amount within the confidence interval.
c. We are 99% confident that the true average cholesterol level for vegans is greater than that of omnivores by an amount outside the confidence interval.
d. We cannot draw a conclusion from the given information.

Determine the equivalent system for the given system of equations.4x − 5y = 2
3x − y = 8

4x − 5y = 2
13x − 8y = 4
4x − 5y = 2
10x + 3y = 15
4x − 5y = 2
13x − 8y = 26
4x − 5y = 2
7x + 6y = 10

Answers

Answer:

4x − 5y = 2

13x − 8y = 26

Step-by-step explanation:

The equivalent system must have the same solution as the given system of equations:

4x − 5y = 2

3x − y = 8

Here we have that:

y = 3x - 8

4x - 5y = 2

4x - 5(3x - 8) = 2

4x - 15x + 40 = 2

-11x = -38

x = (38)/(11)

y = 3x - 8 = (3*38)/(11) - (88)/(11) = (26)/(11)

Now, we have to verify which of these systems have this answer:

4x − 5y = 2

13x − 8y = 4

13x - 8y = 4

13(38)/(11) - 8(26)/(11) = (286)/(11) \neq 4

4x − 5y = 2

10x + 3y = 15

10x + 3y = 15

10(38)/(11) + 3(26)/(11) = (458)/(11) \neq 15

4x − 5y = 2

13x − 8y = 26

4x - 5y = 2

4(38)/(11) - 5(26)/(11) = (22)/(11) = 2

13x - 8y = 26

13(38)/(11) - 8(26)/(11) = (286)/(11) = 26

This is the correct answer

So this is the correct answer

4x − 5y = 2

7x + 6y = 10

Answer:

The answer is

(4x - 5y = 2) and (13x - 8y =26)

What is the transformations of f(x) = - 2lx - 3| + 1 from the parent function f(x) =|x|

Answers

The transformations of f(x) = - 2lx - 3| + 1 from the parent function f(x) =|x|

Horizontal Shift: Right 3 Units

Vertical Shift: Up 1 Units

Reflection about the x-axis: Reflected

Vertical Stretch: Stretched

What is Transformation equation ?

Transformation of an equation into another equation whose roots are. reciprocals of the roots of a given equation we replace x→x1. 2.

Given,

Parent function f(x) = |x|

f(x) = - 2 lx - 3| + 1

Assume that f(x) = |x| is y = |x|  and,

f(x) = - 2 lx - 3| + 1 is g(x) = - 2 lx - 3| + 1

The transformation from the first equation to the second one can be found by finding a, h, and k

y = a |x−h| + k

find a, h, k in f(x) = - 2lx - 3| + 1

a = -2, h = -3, k = 1

Horizontal shift depends on the value of h,

g(x) = f(x + h) ---- The graph is shifted to the left h units.

g(x) = f(x - h) ---- The graph is shifted to the right h units.

so, h = -3 then horizontal shift will be right 3 units

The vertical shift depends on the value of k,

g(x) = f(x) + k  -------  The graph is shifted up k units.

g(x) = f(x) - k   --------  The graph is shifted down k units.

so, k = 1 then the vertical shift will be 1 unit up

The sign of a describes the reflection across the x-axis,

−a means the graph is reflected across the x-axis.

Reflection about x-axis is reflected

The value of a describes the vertical stretch or compression of the graph

a > 1,  vertical stretch will be narrower

a < 1, vertical stretch will be wider

so, vertical stretch is Stretched

Hence, The transformations of f(x) = - 2lx - 3| + 1 from the parent function f(x) =|x|

HorizontalShift: Right 3 Units

Vertical Shift: Up 1 Units

Reflection about the x-axis: Reflected

Vertical Stretch: Stretched
