Answer:

h(x) = 10x

Step-by-step explanation:

given:

f(x) = 3x-1 and g(x)= 4x-2

h(x) = 2 f(x) + g(x)

= 2 (3x+1) + (4x-2)

= 6x + 2 + 4x - 2

= 10x

The question revolves around combining functions in mathematics. To solve for h(x) when h(x) is equal to 2f(x) + g(x), we substitute f(x) and g(x) values into the equation for h(x) and simplify the resulting expression. Our calculated function h(x) = 10x - 4.

This is a question about combining function operations. We have been given two functions f(x) = 3x-1 and g(x) = 4x-2, and asked to find h(x) = 2f(x) + g(x).

To solve it, we must substitute f(x) and g(x) into our equation for h(x):

So, the function h(x) when h(x) is = 2f(x) + g(x) is h(x) = 10x - 4.

Answer:

The sum of the first 5 terms of the series is 77.

Step-by-step explanation:

1. Let's review the information provided to us for solving the sum of the first 5 terms of the series:

1st term = 7

2nd term = - 14

3rd term = 28

4th term = - 56

2. Let's solve the sum of the first 5 terms of the series:

Aₙ = Aₙ₋₁ * -2 ; A₁ = 7

A₁ = 7

A₂ = A₁ * -2 = 7 * - 2 = - 14

A₃ = A₂ * - 2 = -14 * - 2 = 28

A₄ = A₃ * - 2 = 28 * - 2 = - 56

A₅ = A₄ * - 2 = -56 * - 2 = 112

Sum of the first 5 terms of the series = 7 - 14 + 28 - 56 + 112

Sum of the first 5 terms of the series = 77

Answer:

Average rate of change= 3

Step-by-step explanation:

Recall the definition of average rate of change of a function [tex]f(x)[/tex] in an interval [tex][a,b][/tex]:

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

In your case:

[tex]f(x) = 3x+4[/tex], and the interval  [tex][a,b][/tex] i  [tex][2,6][/tex], therefore:

Average rate of change = [tex]\frac{f(6)-f(2)}{6-2}=\frac{f(6)-f(2)}{4}[/tex]

Now we evaluate the function at the two requested points:

[tex]f(x)=3x+4\\f(6)=3(6)+4=18+4=22\\f(2)=3(2)+4=6+4=10[/tex], then [tex]f(6)-f(2)=22-10=12[/tex]

So finally the Average rate of change is: [tex]\frac{f(6)-f(2)}{6-2}=\frac{12}{4} =3[/tex]

Answer:  The second one is not clarified give us the full clarification please....

Step-by-step explanation:

Let's evaluate the two inequalities:

1. 9g - 6 > 12g + 1

Subtracting 9g from both sides gives:

-6 > 3g + 1

Subtracting 1 from both sides gives:

-7 > 3g

Dividing both sides by -3 (and flipping the inequality sign) gives:

g < 7/3

1. 4 > + 8

This inequality is not correct, as it is missing a term on the right-hand side. It should be something like:

4 > x + 8

Subtracting 8 from both sides gives:

-4 > x

Without more information, we can't determine the value of x.

Answer:

The rate of interest paid on the principal amount is 8%.

Step-by-step explanation:

Here, Principal Amount = $2,000

Time = 3 months = (3/ 12 ) Years = 0.25 years

Rate = R

Interest Amount  = $40

Now, as we know :

Simple Interest  = [tex]\frac{P \times R \times T}{100}[/tex]

⇒[tex]40  = \frac{2,000 \times R \times 0.25}{100}\\\implies R = \frac{40 \times 100}{2000 \times 0.25}   =8[/tex]

or, R = 8%

Hence, the rate of interest paid is 8%.

All computers are on sale for 10% off the original price. If x is the original price of the computer, then the function that represents the price after only a 10% discount is: P(x) = x - 0.1x P(x) = 0.9x The function that gives the price, C, if only a $150 coupon is used is: C(x) = x - 150 Choose the composition function that gives the final sale price after a 10% discount is followed by a $150 coupon

The final price of the computer after both discounts is T(x) = 0.9x - 150

We have been given that all computers are on sale for 10% off the original price. If x is the original price of the computer, then the function that represents the price after only a 10% discount is:

P(x) = x - 0.1x

P(x) = 0.9x  

The function that gives the price, C, if only a $150 coupon is used is:

C(x) = x - 150  

We need to choose the composition function that gives the final sale price after a 10% discount is followed by a $150 coupon.

So, we have to formulate a function to combine both the discounts.

The price after 10% discount is 0.9x and the price after $150 coupon is x-150.

So, the composite function that gives the final sale price after 10% discount followed by $150 is given as follows:

Let the final price be denoted as T(x)

Therefore,

T(x) = original price - 10% discount - $150 coupon

T(x) = x - 10% of x -150

T(x) = x - 0.1x - 150

T(x) = 0.9x -150

Hence the final price of the computer after both discounts is T(x) = 0.9x-150

[tex]\int\frac{x^{4}}{x^{4} -1}dx = x + \frac{1}{4} ln(x-1) - \frac{1}{4} ln(x+1)-\frac{1}{2} arctanx + c[/tex]

Step-by-step explanation:

[tex]\int\frac{x^{4}}{x^{4} -1}dx[/tex]

Adding and Subtracting 1 to the Numerator

[tex]\int\frac{x^{4} - 1 + 1}{x^{4} -1}dx[/tex]

Dividing Numerator seperately by [tex]x^{4} - 1[/tex]

[tex]\int 1 + \frac{1}{x^{4}-1 }\, dx[/tex]

Here integral of 1 is x +c1 (where c1 is constant of integration

[tex]x + c1 + \int\frac{1}{(x-1)(x+1)(x^{2}+1)}\, dx[/tex]----------------------------------(1)

We apply method of partial fractions to perform the integral

[tex]\frac{1}{(x-1)(x+1)(x^{2}+1)}[/tex] = [tex]\frac{A}{x-1} + \frac{B}{x+1} + \frac{C}{x^{2} + 1}[/tex]------------------------------------------(2)

[tex]\frac{1}{(x-1)(x+1)(x^{2}+1)} = \frac{A(x+1)(x^{2} +1) + B(x-1)(x^{2} +1) + C(x-1)(x+1)}{(x-1)(x+1)(x^{2} +1)}[/tex]

1 = [tex]A(x+1)(x^{2} +1) + B(x-1)(x^{2} +1) + C(x-1)(x+1)[/tex]-------------------------(3)

Substitute x= 1 , -1 , i in equation (3)

1 = A(1+1)(1+1)

A = [tex]\frac{1}{4}[/tex]

1 = B(-1-1)(1+1)

B = [tex]-\frac{1}{4}[/tex]

1 = C(i-1)(i+1)

C = [tex]-\frac{1}{2}[/tex]

Substituting A, B, C in equation (2)

[tex]\int\frac{x^{4}}{x^{4} -1}dx[/tex] = [tex]\int\frac{1}{4(x-1)} - \frac{1}{4(x+1)} -\frac{1}{2(x^{2}+1) }[/tex]

On integration

Here [tex]\int \frac{1}{x}dx = lnx and \int\frac{1}{x^{2}+1 } dx = arctanx[/tex]

[tex]\int\frac{x^{4}}{x^{4} -1}dx[/tex] = [tex]\frac{1}{4} ln(x-1)[/tex] - [tex]\frac{1}{4} ln(x+1)[/tex] - [tex]\frac{1}{2} arctanx[/tex] + c2---------------------------------------(4)

Substitute equation (4) back in equation (1) we get

[tex]x + c1 + \frac{1}{4} ln(x-1) - \frac{1}{4} ln(x+1) - \frac{1}{2} arctanx + c2[/tex]

Here c1 + c2 can be added to another and written as c

Therefore,

[tex]\int\frac{x^{4}}{x^{4} -1}dx = x + \frac{1}{4} ln(x-1) - \frac{1}{4} ln(x+1)-\frac{1}{2} arctanx + c[/tex]

Answer:

55.19 degrees

Step-by-step explanation:

See the given diagram of the triangle attached to this question.

This is a right triangle and one of its angles other than 90° is x degrees.

Now, if we assume c is the hypotenuse and a is the perpendicular, then we can write that  

[tex]\sin x = \frac{\textrm{Perpendicular}}{\textrm {Hypotenuse}} = \frac{a}{c}[/tex]

Now, it is given that a = 7.8 cm and c = 9.5 cm.

Therefore, [tex]\sin x = \frac{7.8}{9.5} = 0.821[/tex]

⇒ [tex]x = \sin^{-1} (0.821) = 55.19[/tex] degrees. (Answer)

Answer:

Angle = 135°

Supplement of the Angle = 45°

Step-by-step explanation:

The complement of an angle, say "x", would be 90 minus that angle:

90 - x

The supplement of an angle, say "y", would be 180 minus that angle:

180 - y

Since we have 1 angle, let it be "x", and that angle is 3 TIMES the SUPPLEMENT of that angle, we can write:

x = 3(180 - x)

Now, we solve for the angle x:

[tex]x = 3(180 - x)\\x = 540 - 3x\\x + 3x = 540\\4x = 540\\x = \frac{540}{4}\\x=135[/tex]

So, the angle is 135°

The supplement of the angle is  180 - 135 = 45°

The measure of the smaller angle is 45 degrees, and the larger angle, which is three times the size of the smaller one, measures 135 degrees.

The subject of this question falls under the branch of Mathematics, specifically geometry. The question deals with supplementary angles, which are pairs of angles that add up to 180 degrees.

Let's denote the smaller angle as 'x.' According to the problem, the larger angle is three times the size of the smaller, thus it is 3x. Because these are supplementary angles, they add up to form 180 degrees. So, we can create this equation: x + 3x = 180.

By simplifying and solving for x, we get: 4x = 180, hence x = 45 degrees. Therefore, the larger angle, which is three times the smaller, is 3*45 = 135 degrees.

In conclusion, the measure of the smaller angle is 45 degrees while the larger angle measures 135 degrees.

Ages of Mark, Brett and Carl are 80 years, 60 years and 70 years respectively.

Solution:

Given that

Brett is 18 years younger than Mark.

Carl is 10 years younger than Mark.

The sum of the ages of Brett, Mark, and Carl is 212

Need to determine age of Brett, Mark, and Carl.

Let assume age of mark in years be represented by variable x

As it is given that Brett is 18 years younger than Mark , so if we subtract 18 from the age of Mark we will get age of Brett ,

=> Age of Brett = x – 18

Also given that Carl is 10 years younger than Mark , so if we subtract 10 from the age of Mark we will get age of Carl ,

=> Age of Carl = x – 10

Given sum of ages of Brett, Mark, and Carl is 212

=> Age of Mark + Age of Brett + Age of Carl = 212

=> x + ( x – 18 ) + ( x – 10) = 212

=> 3x – 28 = 212

=> 3x = 212 + 28

Age of Mark = x = 80 years

Age of Brett = x – 18 = 80 – 18 = 62 years

Age of Carl = x – 10 = 80 – 10 = 70 years

Hence Ages of Mark , Brett and Carl are 80 years, 60 years and 70 years respectively.

The question is missing the figure. So, the figure is attached below.

Answer:

237.375 ft³

Step-by-step explanation:

Given:

Side length of bigger cube is, [tex]S_1=8\ ft[/tex]

Side length of smaller cube is, [tex]S_2=6.5\ ft[/tex]

Now, volume of the bigger storage unit is given as:

[tex]V_1=S_1^3\\V_1=S_1\times S_1\times S_1\\V_1=8\times 8\times 8=512\ ft^3[/tex]

Volume of the smaller storage unit is given as:

[tex]V_2=S_2^3\\V_2=S_2\times S_2\times S_2\\V_2=6.5\times 6.5\times 6.5=274.625\ ft^3[/tex]

Now, difference in the volume of the two storage units is given as:

[tex]V_1-V_2=512-274.625=237.375\ ft^3[/tex]

Therefore, the difference in their volumes is 237.375 ft³.

To find the difference in volume between two cube-shaped storage units, determine the length of one side for each cube, calculate their volumes with the formula 'Volume = side length cubed', and subtract one volume from the other.

To calculate the difference in volume between the two cube-shaped storage units, follow these steps:

For example, let's assume the side length of cube 1 is 2 meters and the side length of cube 2 is 3 meters. The volume of cube 1 will be 2^3 or 8 m³ and the volume of cube 2 will be 3^3 or 27 m³. The difference in volume between the two cubes would be 27 m³ - 8 m³ = 19 m³.
