The square root of (-5x)^3, for which values of x does this expression make sense?

Answer:

√53 or 7.28

Step-by-step explanation:

To find the length of the line segment from the point (4, 2) to the point (-3, 4), you can use the distance formula, which is:

distance = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the coordinates of the two points, you get:

distance = √((-3 - 4)^2 + (4 - 2)^2)

Simplifying this expression gives:

distance = √((-7)^2 + (2)^2)

Which simplifies to:

distance = √(49 + 4)

Which simplifies to:

distance = √53

So the length of the line segment from the point (4, 2) to the point (-3, 4) is approximately 7.28.

There are 2 hours of television must you watch in the eighth week to meet your goal.

What is television?

The transmission of audio and video data electronically between a source and a recipient.

The primary use of television is to transmit shows for entertainment, information, and education. Television is a system for transmitting visual images and sound that are reproduced on screens.

Given: You want to limit the amount of television you watch to an average of at most 1.5 hours per week during an 8-week period.

Suppose x is the hours of watching television in the 8th week.

Let the average of watching television per week is 1.5.

⇒

[tex]\frac{1 + 1.5 + 0.5 + 3 + 1.5 + 2 + 0.5 + x}{8} = 1.5\\ \frac{10+x}{8}=1.5 \\10+x = 12\\x = 12-10\\x = 2[/tex]

Hence, there are 2 hours of television must you watch in the eighth week to meet your goal.

The number of adults who can still enter will be determined by the linear equation solution.

let

20c = 15a ; 5 divided by both sides

4c = 3a

Another 3 kids can enter the elevator if there are already 17 in it.

The fact that;

3c =  9/4 a

3c =  9/4 a

3c = 2.25 a

The amount invested at 8% and 6% is 1000 and 1900 respectively.

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, The person invested $2900 in two mutual funds and the total profit is $194.

Let the amount invested at 8% is x, then the amount invested at 6% is:

2900-x

Since the total profit is $194, it follows:
8% of x + 6% of (2900 - x) = 194

8x/100 + 6(2900 - x)/100 = 194

8x + 17400 - 6x = 19400

2x = 19400 - 17400

2x = 2000

x = 1000

The amount invested at 6% is:
2900 - 1000

= 1900

Hence, the amount invested at 8% and 6% is 1000 and 1900 respectively.

The question is an illustration of equation of circles.

The equation of the dartboard circle is:  [tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]

Brian's dart lands on the dartboard because D = 11.5 feet , 5 feet is within the circumference of the dartboard.

Given that,

h = 5 feet 8 inches ---- the height at which the dartboard was hung

d = 18 inches in diameter ---- the diameter of the dartboard

B = 12 feet --- the bull's eye

D = 11.5 feet , 5 feet --- Brian's dart

Equation of the circle

First, we convert all units to feet

This is done by dividing inches units by 12

h = 5 feet 8 inches

h = 5 ft + 8/12 ft

h = 5 ft + 2/3 ft

Take LCM

h = [tex]\frac{15+2}{3}[/tex] ft

h = [tex]\frac{17}{3}[/tex] ft

d = 18 inches

d = [tex]\frac{18}{12}[/tex] ft

d = [tex]\frac{3}{2}[/tex] ft

Divide by 2 to calculate radius

r = [tex]\frac{3}{2*2}[/tex] ft

r = [tex]\frac{3}{4}[/tex] ft

To find the equation of a circle when you know the radius and centre, use the formula as [tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex] , where represents the centre of the circle, and is the radius.

The equation of the circle is represented as:

[tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex]

In this case:

a = B = 12 feet -- the distance between the bull's eye and the wall

b = h = [tex]\frac{17}{3}[/tex] ft  ---- the height at which the dartboard was hung

So, we have:

[tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex]

[tex](x-12)^{2} +(y-\frac{17}{3}) ^{2} = (\frac{3}{4}) ^{2}[/tex]

Evaluate the exponents

[tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]

Hence, the equation of the circle is:

[tex](x-12)^{2}+(y-\frac{17}{3}) ^{2} =\frac{9}{16}[/tex]

Does Brian’s dart land on the dartboard?

Yes her dart lands on the dartboard because

D = 11.5 feet , 5 feet is within the circumference of the dartboard

Step-by-step explanation:

The mean , standard deviation, and the variance of each binomial experiment using given probability and sample of restaurant owners surveyed is equal to 54.52 , 1.808, 3.2712 respectively.

As given in the question,

Let success be defined by health department inspection is passed by restaurant

Probability of success rate 'p' = 0.94

Value of ' 1 - p ' = 1 - 0.94

                        = 0.06

Number of owners of restaurant which are surveyed 'n' = 58

For the given binomial experiments calculation of the following distributions are:

Mean 'μ' = np

             = 58 × 0.94

             = 54.52

Standard deviation 'σ' = √ np (1 - p)

                                   = √ 58 × 0.94 × 0.06

                                   = √3.2712

                                   = 1.808

Variance 'σ²' =  np( 1 - p )

                    = 58 × 0.94 × 0.06

                   = 3.2712

Therefore, the mean , standard deviation , and the variance from the given probability and sample size is equal to 54.52 , 1.808, 3.2712 respectively.

Answer: 1452 units^3

The required volume of the cylinder with a height of 12 units and radius of 11 units is 1452π cubic units.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

The formula for the volume of a cylinder is given as:

V = πr²h

Where V is the volume of the cylinder, r is the radius of the cylinder, and h is the height of the cylinder.

Substituting the given values, we get:

V = π(11)²(12)

= π(121)(12)

= 1452π cubic units

Therefore, the volume of the cylinder with a height of 12 units and radius of 11 units is 1452π cubic units.

The values of x and w on the triangle are given as follows:

w = 14.4, x = 11.2.

The values of x and w are obtained applying the trigonometric ratios, as the triangle is a right triangle.

The three trigonometric ratios are given as follows:

For the angle of 48º, we have that:

Hence:

tan(48º) = 16/w

w = 16/tan(48º)

w = 14.4.

For the angle of 32º, we have that:

Hence:

tan(32º) = 16/(14.4 + x)

tan(32º)(14.4 + x) = 16

x = (16 - 14.4tan(32º))/tan(32º)

x = 11.2.

Answer:

Step-by-step explanation:

^

Sine and cosine are the fundamental trigonometric functions associated to the sides of a right triangle and tangent is a derivate trigonometric function.

Let be a right triangle, whose features are introduced in the figure attached below. The side with measure y is the side opposite to the angle θ, whereas the side with measure x is the side adjacent to the angle θ. The side with measure r represents the hypotenuse of the right triangle, which can be found by means of Pythagorean theorem:

r = √(x² + y²)

Trigonometric functions are trascendent functions that relates two sides of the right triangle. There are two fundamental trigonometric functions and four derivate trigonometric functions:

Fundamental

sin θ = y / r = (Opposite side) / (Hypotenuse)

cos θ = x / r = (Adjacent side) / (Hypotenuse)

Derivate

tan θ = sin θ / cos θ = y / x = (Opposite side) / (Adjacent side)

cot θ = 1 / tan θ = cos θ / sin θ = x / y = (Adjacent side) / (Opposite side)

sec θ = 1 / cos θ = r / x = (Hypotenuse) / (Adjacent side)

csc θ = 1 / sin θ = r / y = (Hypotenuse) / (Opposite side)
