Answer:

The given expression is equivalent to 3(2^(3/8))x.

Step-by-step explanation:

The given expression (3 root 8^1/4 x) can be written as:

3√(8^(1/4))x

we know that 2^3 = 8

= 3√(2^(3/4))x

We know that √x = (x)^(1/2)

= 3(2^((3/4)(1/2))x

Powers multiply with each other, 3*1/4*2 = 3/8

= 3(2^(3/8))x

For one uniform 15/4 m of cloth is needed, since we need 26 uniforms week need 26 time that much cloth. Set up and multiply the equation like so...

Answer:

y = - [tex]\frac{1}{3}[/tex] x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 9, 6)

m = [tex]\frac{6-2}{-9-3}[/tex] = [tex]\frac{4}{-12}[/tex] = - [tex]\frac{1}{3}[/tex], hence

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 9, 6), then

6 = 3 + c ⇒ c = 6 - 3 = 3

y = - [tex]\frac{1}{3}[/tex] x + 3 ← in slope- intercept form

The percentage of bags contain between 65 and 85 potato chips is 95%.

Step-by-step explanation:

A probability distribution that is symmetric and the data near the mean are more frequent than far is known as a normal distribution. Normal distributions are important in statistics and are often used to represent real-valued random variables.

The formula for finding the percentage of bags using normally distributed is given as

f(x) = (1 / sigma * square root 2 *pi) * e^((-1/2)*((x-u)/sigma))

Substituting the values of mean and standard deviation,

The percentage of bags contain between 65 and 85 potato chips is 95%.

Final answer:

Using the empirical rule, approximately 95% of potato chip bags will contain between 65 and 85 chips, as this range spans two standard deviations away from the mean in a normal distribution.

Explanation:

The question is regarding the percentage of potato chip bags that contain a specific number of chips based on a normal distribution. With a mean of 75 and a standard deviation of 5, the range of chips in the bags is between 65 and 85. To find this percentage, we use the empirical rule, sometimes referred to as the 68-95-99.7 rule, which states that approximately 68% of the data within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.

Since the range from 65 to 85 chips spans two standard deviations from the mean (65 is 10 chips away from 75 which is two standard deviations as 5*2=10, and the same logic applies for 85), we can say that approximately 95% of the bags will contain between 65 and 85 potato chips.

Answer:

Step-by-step explanation:

This problem is quite simple; that is, if you know the proper formula that must be applied in finding the distance. The formula for finding the distance between two coordinate points is: √(x2-x1)^2+(y2-y1)^2. Now, obviously, (x2-x1)^2 and (y2-y1)^2 are both under the radical, where x2 and y2 represent the xy coordinates of point A (7,4) and x1 and y1 represent the xy coordinates of point B (-8,4). Now, all you must do is plug the points into the distance formula to get the answer, 15.

The distance between the two points is 15 units.

The coordinate points are A (7, 4) and B (-8,4).

The formula to find the distance between two coordinate points is Distance=[tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2}}[/tex].

Now, the distance between two coordinate points=[tex]\sqrt{(-8-7)^{2} +(4-4)^{2}}[/tex]

=√225

=15 units

Therefore, the distance between the two points is 15 units.

ANSWER

C) (6,-8)

EXPLANATION

The equations are:

[tex]y = \frac{1}{3}x - 10[/tex]

and

[tex]2x+y=4[/tex]

We substitute the first equation into the second equation to get:

[tex]2x + \frac{1}{3}x - 10 = 4[/tex]

We multiply through by 3 to get:

[tex]6x + x - 30= 12[/tex]

Group similar terms,

[tex]6x + x = 30 + 12[/tex]

[tex]7x = 42[/tex]

Divide both sides by 7 to get,

[tex]x = \frac{42}{7} = 6[/tex]

Put this value of x into the first equation to get;

[tex]y = \frac{1}{3} (6) - 10[/tex]

[tex]y = 2 - 10 = - 8[/tex]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut-off point with the y axis

[tex]m = \frac {y2-y1} {x2-x1}[/tex]

We have the following points:

[tex](x1, y1): (- 7,25)\\(x2, y2): (- 4,13)[/tex]

Substituting the values:[tex]m = \frac {13-25} {- 4 - (- 7)} = \frac {-12} {- 4 + 7} = \frac {-12} {3} = - 4[/tex]

Thus, the line is of the form:

[tex]y = -4x + b[/tex]

We substitute one of the points and find "b":

[tex]13 = -4 (-4) + b\\13 = 16 + b\\b = 13-16 = -3[/tex]

Finally we have to:

h = (10 ft)(4.01) = 40.1 ft

Step-by-step explanation:

The tangent function relates this elevation to the horizontal distance (10 ft) and the angle of elevation (76 degrees):

                               opp           h

tan 76 degrees = --------- = ------------- = 4.01

                                adj         10 ft

Therefore , h = (10 ft)(4.01) = 40.1 ft

Answer: 40 ft

Step-by-step explanation:

You can find the height of the statue by solving the right triangle.

In this case the adjacent side of the triangle is the horizontal distance to the statue (10 ft). The height of the statue is the opposite side to the angle of 76 °.

By definition, the tangent of an angle is:

[tex]tan(\theta) = \frac{opposite}{adjacent}[/tex]

In this case

[tex]\theta=76\°\\\\opposite = h\\\\adjacent = 10\ ft[/tex]

Therefore

[tex]tan(76) = \frac{h}{10}[/tex]

[tex]h=tan(76) * 10\\\\h=40\ ft[/tex]

Answer:

y = 2x + 2

Step-by-step explanation:

Start at point (2, 6).

Go up 2 units up (rise = 2) and 1 unit right (run = 1). Now you are at point (3, 8) which is on the graph.

slope = rise/run = 2/1 = 2

The slope of the graph is 2. m = 2

Now look at point (0, 2). The y-intercept is 2. b = 2

The equation is

y = mx + b

y = 2x + 2

Answer:

y = 2x + 2

Step-by-step explanation:

Here we're asked to come up with a linear function relating x and y.

First we find the slope of the line.  As we move from (0, 2) to (3, 8), x increases by 3 and y by 6.  Thus, the slope is

m = rise / run = 6 / 3 = 2.  

Plugging givens into the slope-intercept formula y = mx + b, we find b:

2 = 2(0) + b, so that b = 2.

Then the desired relationship between x and y is y = 2x + 2.

To solve this you must use Pythagorean theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 5

b = 8

c = x

^^^Plug these numbers into the theorem

[tex]5^{2} +8^{2} =x^{2}[/tex]

simplify

25 + 64 = [tex]x^{2}[/tex]

89 = [tex]x^{2}[/tex]

To remove the square from x take the square root of both sides to get you...

Step-by-step explanation:

Points to remember

Pythagorean theorem

For a right triangle,

Base² + Height² = Hypotenuse²

To find the vale of x

From the figure we can see a right triangle,

Base = 8 units and height = 5 units

Hypotenuse² = Base² + Height²

x² = 8² + 5²

 = 64 + 25

 = 89

x = √89

Answer:

f(x)=4(3)^2

(2,36)

36=4(3)^2

36=4(9)

36=36

Step-by-step explanation:

Answer: Hi! here you want a function that pases through the point (2,36)

it means, a function f(x) so f(2) = 36.

Also, f(x) must be an exponential function, this means that f(x) = [tex]a^{x}[/tex]

where a is a real number.

then  [tex]a^{2}[/tex] = 36

so a = [tex]\sqrt{36}[/tex] = ± 6.

then your function can be f(x) = [tex]-6^{x}[/tex] or [tex]6^{x}[/tex].

Notice that i used a very simplest example of exponential function. You actually can found lots of exponential functions F(x) that passes through the point (2,36).

We know that the whole angle of the triangle is 73. Since the known angle is 45 degrees, we need to find out what the other is.

Subtract 45 from 73 to find the angle of the unknown triangle.

73-45=28.

Now that we know the value of the unknown triangle, solve for x

Make an equation.

2x+5=28

Subtract 5 on both sides.

2x=23

Divide 23 by 2 to isolate x.

Answer:

The volume of the sphere is 24 cm³

Step-by-step explanation:

* Lets explain the difference between the cylinder and the sphere

- The cylinder has two circular bases and a curved surface

- The bases of the cylinder have radius r and the curved surface has

 a height h

- The volume of the cylinder = area of its base × its height

∵ The area of the circle is πr²

∴ The volume of the cylinder is V = π r² h

- A sphere is a perfectly round geometrical object in three-dimensional

 space

- It the set of points that are all at the same distance r from a given point

 that means its radius equals its height

- The volume of the sphere = 4/3 π r³

* Now lets solve the problem

∵ The cylinder and the sphere have the same radius and height

∵ The volume of the cylinder is 18 cm³

- Lets equate the rule of the volume of the cylinder by 18

∵ The volume of the cylinder = π r² h

∴ π r² h = 18 ⇒ divide both side by π

∴ r² h = 18/π

- The sphere and the cylinder have the same radius and height

∴ The radius and height of the sphere have the same value of the

   cylinder

∵ The the height of the sphere is its radius

∴ r²h of the cylinder = r³ in the sphere

∴ r³ = 18/π

- Substitute this value in the rule of the volume of the sphere

∵ The volume of the sphere = 4/3 π r³

∴ The volume of the sphere = 4/3 π (18/π) ⇒ cancel π's

∴ The volume of the sphere = 4/3 (18) = 24 cm³

* The volume of the sphere is 24 cm³
