Which ratio is greater than StartFraction 5 Over 8 EndFraction?

The set the describes the domain of P(h) is (b)  {h| 0 ≤ h ≤ 60}

In this case, the domain represents the set of hours he is permitted to work

From the question, we understand that he cannot work more than 60 hours

This means that, the least number of hours to work is 0, and the highest is 60

So, the domain is 0 to 60

When represented properly, the domain of P(h) is (b)  {h| 0 ≤ h ≤ 60}

Answer:

768

Step-by-step explanation:

let C represent cost and w weight, then the equation relating them is

C = kw² ← k is the constant of variation

To find k use the condition w = 20, C = 4800, that is

4800 = k × 20² = 400k ( divide both sides by 400 )

12 = k

C = 12w² ← equation of variation

When w = 8, then

C = 12 × 8² = 12 × 64 = 768

Answer:

25.5x

Step-by-step explanation:

Simply convert the fraction into a decimal and add.

21/2x = 10.5x

10.5x + 15x = 25.5x

If you want to keep it in fraction form, 15 is 30/2, so,

30x/2 + 21x/2 = 51x/2

Answer:

51x/2

Step-by-step explanation:

Add it like a normal fraction equation

Have them both with the same denominator of 2

30/2 + 21/2

Add the numerators

51/2

Now put the x into the numerator since it started as in the numerator

Answer:

Brian = 55

Son = 29

Step-by-step explanation:

Let the ages of Brian and his son be

x +26 and x

Given that :

x + x + 26 = 84

2x + 26 = 84

2x = 58

x = 29.

We know that x is the age of Brian's son. so, Brian's age is 29 + 26 = 55

Answer:  A) 7 real zeros and 6 turning points at 0, 2, 4

Step-by-step explanation:

x⁷ - 6x⁶ + 8x⁵

The degree (largest exponent) is 7 so the maximum number of real zeros is 7.

Factor out x⁵

x⁵(x² - 6x + 8)

Factor the quadratic

x⁵(x - 2)(x - 4)

Set each factor equal to 0 and solve for x

x⁵ = 0         --> x = 0  (multiplicity of 5)

x - 2 = 0     --> x = 2

x - 4 = 0     --> x = 4

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete answer.

A given line has the equation 2x + 12y = −1.

What is the equation, in slope-intercept form, of the line that is perpendicular to the given line and passes through the point (0, 9)?

General formula of equation of a line is exspressed as y = mx+c

m = gradient or slope  

c = intercept

Step 1: we need to first get the slope of the given equation of a line by rewriting the equation in standard form y = mx+c

2x + 12y = −1

12y = -1-2x

y = -1/12-2x/12

y = -1/6 x - 1/12

From the equation above, it can be seen that the slope (m) of tghe line is -1/6.

Since both lines are perpendicular, the slope of the unknown line will be;

M = -1/m

M = -1/(-1/6)

M = 6

Step 2: We will find the intercept c by substituting the point (0,9) and the slope into the equation y = mx+c

9 = 6(0)+ c

c = 9

Stwp 3: We will find the equation of the line perpendicular to the given line by substituting the value of m and c into the equation y = mx+c

y = 6x+9

y-6x = 9

The equation in slope-intercept form, of the line that is perpendicular to the given line and passes through the point (0, 9) is y-6x = 9

Answer:

y-6x=9

Answer: A) 20.9 ; B) 34years

Step-by-step explanation:

Given the following :

AGE (X) - - - - - - - 19 - -20 - - - 21 - - - 22 - - - 23

FREQUENCY (F) - 2 - - 3 - - - - 1 - - - - 4 - - - - 1

A)

MEAN(X) = [AGE(X) × FREQUENCY (F)] ÷ SUM OF FREQUENCY

F*X = [(19 * 2) + (20 * 3) + ( 21 * 1)+(22 * 4)+(23 * 1)]

= 38 + 60 +21 + 88 + 23 = 230

SUM OF FREQUENCY = 2 + 3 + 1 + 4 + 1= 11

MEAN(X) = 230 / 11

X = 20.9

B)

WHEN A NEW PLAYER WAS ADDED :

MEAN (X) = 22

Let age of new player = y

Sum of Ages = 19 + 19 +20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 + y

Number of players = 11 + 1 = 12

Mean(x) = sum of ages / number of players

New mean (x) = 22

x = (230 + y) / 12

22 = (230 + y) / 12

Cross multiply

264 = 230 + y

y = 264 - 230

y = 34 years

Amount in account after one year, two and three years are respectively  $2,060 , $2,121.8 and $2,185.45

Given:

Principal amount = $2,000

Rate of interest = 3% = 0.03

Amount in account after one year

A = P(1+r)ⁿ

A = 2,000(1+0.03)¹

A = 2,000(1.03)¹

A = 2,000(1.03)

A = $2,060

Amount in account after two year

A = P(1+r)ⁿ

A = 2,000(1+0.03)²

A = 2,000(1.03)²

A = 2,000(1.0609)

A = $2,121.8

Amount in account after three year

A = P(1+r)ⁿ

A = 2,000(1+0.03)³

A = 2,000(1.03)³

A = 2,000(1.092727)

A = $2,185.45

Answer:

Slope = [tex]-\frac{3}{4}[/tex]

y-intercept = 2

Equation of the line 't': [tex]y=-\frac{3}{4}x+2[/tex]

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is represented by,

Slope 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Since line 't' is passing through two points (0, 2) and (8, -4),

Slope of the line 't' = [tex]\frac{2+4}{0-8}[/tex]

                           m = [tex]-\frac{6}{8}[/tex]

                           m = [tex]-\frac{3}{4}[/tex]

Since y-intercept of a line is the value of 'y' for x = 0 [from point (0, 2) lying on this line]

Therefore, Y-intercept of line 't' = 2

Slope intercept of an equation is,

y = mx + b

where m = slope of the line

b = y-intercept

Therefore, equation of the line 't' will be,

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

A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Given:

y = negative x + 3

The above phrase can be written as,

y = -x + 3

Calculate the slope as shown below,

Slope = -1

The x-intercept can be calculated as,

0 = -x + 3  (y is zero at the x-axis)

x = 3

The x-intercept can be calculated as,

y = 0 + 3 (y is zero at the x-axis)

y = 3

Mark the coordinates (0, 3) and (3, 0) on the graph and join the points you will get the graph.

Answer:

Step-by-step explanation:

2/3y + 15 = 9

Subtract 15 from each side

2/3y + 15-15 = 9-15

2/3y = -6

Multiply each side by 3/2 to isolate y

3/2 * 2/3y = -6 *3/2

y = -9

Answer:

y = - 9

Step-by-step explanation:

2/3y + 15 = 9

Subtract 15 on both sides.

2/3y = 9 - 15

2/3y = - 6

Multiply both sides by 3/2.

y = - 6 × 3/2

y = -18/2

y = -9

Mean: 12.9

Standard deviation: 14.8

Step-by-step explanation:

The mean is calculated adding all of the values and dividing by the number of elements:

[tex]m=\frac{2+3+7+12+1+4+27+49+11}{9}=\frac{116}{9}=12.9[/tex]

to find the standard deviation, we first find the variance (which is defined as the sum of all the elements subtracting the mean and squared and then dividing by the total amount of elements):

[tex]v=\frac{(2-12.9)^2+(3-12.9)^2+(7-12.9)^2+(12-12.9)^2+(1-12.9)^2+(4-12.9)^2+(27-12.9)^2+(49-12.9)^2+(11-12.9)^2}{9}\\[/tex]

[tex]v=\frac{1978.89}{9}\\[/tex]

[tex]v=219.88[/tex]

Noe that we have the variance, we can calculate the standard deviation.

The stardard deviation is defined as the squared root of the variance:

[tex]standardDeviation=\sqrt{v}[/tex]

we substitute the variance:

[tex]standardDeviation=\sqrt{219.88} \\standardDeviation=14.8[/tex]

Answer:

Length is 11.052cm

Width is 3.684cm

Height is 7.386cm

Step-by-step explanation:

Let length be x, width y and height Z

Width (y) = X/3 , height (z) = 2x /3

volume =xyz

volume = x(x/3)(2/3)x

Volume = (2/9)x³

But Volume =300

300= (2/9)x³

300/(2/9) = x³ (make x³ the subject to find x )

1350 = x³

x=3√(1350)

x=11.052cm

Length is 11.052cm

Width = x/3 =11.052 /3

= 3.684cm

Height = 2x/3 = 2(11.052) /3

= 7.368cm

You can check it by multiplying LWH to see if you get 300 (the volume)

[tex]\frac{x}{x^2+3x+2}[/tex] + [tex]\frac{3}{x+1}[/tex]

Before we can add the fractions we require them to have a common denominator.

Factor the denominator of the first fraction

[tex]\frac{x}{(x+1)(x+2)}[/tex] + [tex]\frac{3}{x+1}[/tex]

Multiply the numerator / denominator of the second fraction by (x + 2)

= [tex]\frac{x}{(x+1)(x+2)}[/tex] + [tex]\frac{3(x+2)}{(x+1)(x+2)}[/tex] ← fractions now have a common denominator

Add the numerators leaving the denominators
