What is the maximum height the cricket reaches? Round to the nearest thousandth.

Answer:

Our mass is not great enough to have enough pull to actually move the pencil.

Objects like a pencil aren't noticeably pulled towards you because the gravitational force between objects with relatively small masses, like you and the pencil, is very weak compared to the Earth's gravitational pull.

The reason why other objects, like your pencil, aren't being pulled towards you is due to the relative mass of the objects and the distance between them.

Although every object with mass exerts a gravitational force on other mass objects, this force is extremely weak unless at least one of the objects is very massive, like Earth.

According to Newton's universal law of gravitation, the force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Given that both you and the pencil have relatively small masses, the gravitational attraction between you is minuscule compared to the gravitational pull of the Earth, which is why the pencil falls to the floor when dropped instead of being pulled towards you.

A control group is beneficial as a comparison reference to isolate the effects of the treatments. Parrots should be randomly assigned to avoid selection bias. Blocking by parrot breed would likely be more effective than by sanctuary, because breed potentially has a greater influence on cognitive health.

The inclusion of a control group provides a reference point for comparison and helps to identify the effects of the medicines by isolating other variables. Without a control group, it would be challenging to discern whether the observed improvements in the parrots' cognitive health were solely due to the medicines or external factors.

The best way to randomly place the parrots into the three groups is by using a random number generator or similar method to ensure equal and unbiased chance of being allocated to any group. This would mitigate any potential bias and ensure the findings are due to the effect of the Medicines and not the selection process.

Blocking by breed might be more beneficial as biological differences among breeds could influence cognitive health and the response to medication. Blocking by sanctuary would be less ideal as cognitive health could be influenced by a variety of situational factors, such as diet and care, which could introduce bias in the results.

Answer:

Answer:

Part 1) m∠EOD=20°

Part 2) m∠AOD=80°

Step-by-step explanation:

Part 1) Find the measure of angle EOD

we know that  °

m∠EOD=m∠EOX-m∠DOX

we have

Observing the figure

m∠EOX=140°

m∠DOX=120°

substitute

m∠EOD=140°-120°=20°

Part 2) Find the measure of angle AOD

we know that  °

m∠AOD=m∠DOX-m∠AOX

we have

Observing the figure

m∠AOX=40°

m∠DOX=120°

substitute

m∠AOD=120°-40°=80°

Step-by-step explanation:

The sum of the internal angle is 360 degrees. Then the measure of angle B is 115°.

It is a polygon that has four sides. In a parallelogram, opposite sides are parallel and equal. And its diagonals intersect at mid-point.

The quadrilateral shown is a parallelogram. The angle A is 65°.

∠D and ∠B are equal because they are alternate angles.

∠A and ∠C are equal because they are alternate angles.

Then the sum of the internal angle is 360 degrees.

∠A + ∠B + ∠C + ∠D = 360

∠A + ∠B + ∠A + ∠B = 360

                 ∠A + ∠B = 180

                          ∠B = 180 - 65

                          ∠B = 115

Thus, the measure of angle B is 115°.

Answer:

I beleive it is C I might be wrong.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

∠ BEF and ∠ CFE are alternate angles and congruent, thus

3x + 20 = 2x + 50 ( subtract 2x from both sides )

x + 20 = 50 ( subtract 20 from both sides )

x = 30

Thus

∠ CFE = 3x + 20 = 3(30) + 20 = 90 + 20 = 110°

∠ CFE and ∠ AEF are same- side interior angles and are supplementary, thus

∠ AEF = 180° - 110° = 70° → B

2) going towards right from 8 with an open circle at 8

Answer:

see below

Step-by-step explanation:

l -4 +2x l -3 > 9

Add 3 to each side

l -4 +2x l -3+3 > 9+3

l -4 +2x l  > 12

We Separate into two inequalities, remembering to flip the negative inequality

 -4+2x>12        or            -4+2x<-12    

Add 4 to each side

  -4+4+2x>12+4   or                  -4+4+2x<-12 +4

2x> 16                      or                     2x< -8

Divide each side by 2

2x/2 > 16/2                  or              2x/2 < -8/2

x > 8    or                                x < -4

Answer:

[tex]sin(-x)[/tex]

Step-by-step explanation:

Odd functions follow the relation of

[tex]f(-x)=-f(x)[/tex]

Lets check for the most trivial value, does

[tex]sin(-0) = -sin(0)[/tex]

Well these values both equal 0, so this is correct!

What about another value?

[tex]sin(- \frac{\pi}{2})=-1\\-sin(\frac{\pi}{2})=-1[/tex]

In-fact this is strictly defined for all values of sin. Meaning that this is an odd function.

The example of an odd trigonometric function is sin(-x).

All functions that involved trig functions could be even, odd, or not. A function could be odd  if f(-x) = - f(x)

So, for sin, it is

sin (-0) = -sin(0)

Since these values both equal 0, so this is right

So, here sine be the odd function and cos is an even function.

Therefore, The example of an odd trigonometric function is sin(-x).

Answer:

17 = 13 cent stamps

9 = 22 cent stamps

Step-by-step explanation:

Here is what we know:

a = 13 cent stamps

b = 22 cent stamps

Total stamps: 26

Total cost $4.19

Now we make equations based on what we know.

a + b = 26

13a + 22b = 419

Now we have to change the first equation so we can solve for the second. To do this, we have to find a similar factor for one of the variables. Let's change a.

Multiply the first equation by 13

13(a + b) = 13(26)

13a + 13b = 338

Now we put the two equations together and subtract. (Don't forget to change all the signs when you subtract)

   13a + 22b = 419

 - 13a -  13b  = - 338

=   0   +  9b   = 81

Solve for b.

9b = 81

b = 9

Plug b into the first equation to get a.

a + b = 26

a + 9 = 26

a = 17

17 = 13 cent stamps

9 = 22 cent stamps

You are done!

Hope this helped! :)

The number of each type of spend should be

17 = 13 cent stamps

9 = 22 cent stamps

Given that,  

Based on the above information, the calculation is as follows:

a + b = 26

13a + 22b = 419

Multiply the first equation by 13

13(a + b) = 13(26)

13a + 13b = 338

 13a + 22b = 419

 0   +  9b   = 81

9b = 81

b = 9

Plug b into the first equation to get a.

a + b = 26

a + 9 = 26

a = 17

Step-by-step explanation:

The equation 2x² - 6x - 20 = 0 is in standard form for a quadratic formula.

The general equation for standard form is: y = ax² + bx + c

We know the area is 36, so we can substitute that in

36=s^2

Take the square root of both sides

6=s

s= 6 feet

One side is 6 feet, so that is how long the board should be cut.

Answer:

No.

Step-by-step explanation:

When you distribute the two factors it would become a perfect square binomial because the -x and the x would cancel out leaving only x^2 -1, which is the difference of two squares.

Answer:

No because the when you distribute it out it would be (x^2 -1) which is not a perfect square trinomial equation. Also it cannot be a perfect square trinomial because one binomial has negative 1 and the other has positive 1 which indicates that it is not a perfect square.

Given:

A composite figure consisting of a cylinder with radius r and height h and a half-sphere with a radius r.

To find:

The total volume of the composite figure.

Solution:

To determine the total volume of the figure, we add the volume of the cylinder and the volume of the half-sphere.

The volume of a cylinder, [tex]V= \pi r^{2} h.[/tex]

The given cylinder has a radius of 3.9 units and a height of 4.3 units. Assume π equals 3.14.

The volume of the cylinder, [tex]V = (3.14)(3.9^{2} )(4.3)= 205.36542[/tex] cubic units.

The volume of a half-sphere, [tex]V= \frac{2}{3} \pi r^{3} .[/tex]

The given half-sphere has a radius of 3.9 units, assume π equals 3.14.

The volume of the half-sphere, [tex]V= \frac{2}{3} (3.14)(3.9^{3} ) = 124.17444[/tex] cubic units.

The total volume of the composite figure [tex]= 205.36542+124.17444=329.53986[/tex] cubic units.

The number of months Landon used the streaming service is given by the equation x = 18 months

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Let the number of months be x

A streaming video company charges $27.50 to set up an account and $12 per month to enjoy the service

Let the total cost be represented as y

So , the value of y = $ 243.50

The inequality equation is 12x + 27.50 < 243.50

12x + 27.50 < 243.50   be equation (1)

On simplifying the equation , we get

Subtracting 27.50 on both sides of the equation , we get

12x < 216

Divide by 12 on both sides of the equation , we get

x < 18

So , the value of x = 18 months
