The fourth option,

[tex](f-g)(x)=11x[/tex]

To solve the problem, we must remember the following property of the functions:

Subtraction of functions:

We have that,

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

We are given the functions:

[tex]f(x)=4x+3[/tex]

and

[tex]g(x)=3-7x[/tex]

So, calculating we have:

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

[tex](f-g)(x)=(4x+3)-(3-7x)[/tex]

[tex](f-g)(x)=4x+3-3+7x[/tex]

[tex](f-g)(x)=4x+7x+3-3=11x[/tex]

Hence, the answer is the fourth option,

[tex](f-g)(x)=11x[/tex]

Have a nice day!

Answer:

(D) (f-g)(x) = 11x

Step-by-step explanation:

You have:

f(x) = 4x + 3

g(x) = 3 - 7x

You want to do f(x) - g(x)... you simply do the operation on their definition...

f(x) - g(x) = 4x + 3 - (3 - 7x) = 4x + 3 - 3 + 7x = 11 x + 0

So, (f-g)(x) = 11x

You can verify it by placing a value for x in both equations.  Let's take x = 3

f(x) = 4x + 3 = 4(3) + 3 = 15

g(x) = 3 - 7x = 3 - 7(3) = -18

f(x) - g(x) = 15 - -18 = 33

(f - g)(x) = 11x = 11 (3) = 33

Yes, (f(x) - g(x)) = (f - g)(x) = 33

Answer:

[tex]3 \sqrt[3]{162} = 3 \sqrt[3]{27} \sqrt[3]{6} = 3(3 \sqrt[3]{6} ) = 9 \sqrt[3]{6} [/tex]

Final answer:

The simplest form of 3 cube root of 162 is 9 cube root 2, with a=9 and b=2 after factoring out the perfect cube within 162.

Explanation:

The student has asked about simplifying the expression 3 cube root of 162 into the form a3 cube root b. The cube root of 162 can be simplified by factoring out cubes. The number 162 is equal to 2 * 81, where 81 is a perfect cube (3³). Thus, we can rewrite 162 as 2 * 3³. When taking the cube root, the cube root of 3³ is 3, and it comes out of the cube root symbol leaving us with 2 inside the cube root. Multiplying this by 3 outside the cube root, we get:

3 * 3 cube root 2 = 9 cube root 2

Therefore, the expression in its simplest form is 9 cube root 2, which follows the format a3 cube root b with a=9 and b=2.

Step-by-step explanation:

Final answer:

A table can simultaneously display yes/no (Boolean) and numeric data. Yes/No fields in databases are often checkboxes representing binary choices, while other columns can store numeric data. The data types assigned to these fields determine how they are sorted and displayed in the table.

Explanation:

Yes, it is entirely possible for a table to display both yes/no and numeric data at the same time. The yes/no data is often referred to as binary, Boolean, or Yes/No datatype, and in databases, it commonly appears as a checkbox. These Yes/No fields contain only two possible values, such as Yes/No, True/False, or On/Off. On the other hand, the numeric data represents quantitative information that can be measured and written down with numbers.

Tables are quite versatile and can conveniently organize complex numerical information, alongside qualitative categories, in a structured format using rows and columns. For example, a table can be used to compare different models of a product using criteria represented by both text and numbers, such as product features ('Yes' for having a feature and 'No' for not having it) and specifications like price or weight (numeric data).

It's important to keep in mind that when designing a database, every field is assigned a datatype based on what type of data it holds. For fields containing text, a 'text' datatype is used; whereas for fields containing numeric values, a 'number' datatype is chosen. The datatype affects how the data is sorted and processed within the table.

For this case we must solve the following questions:

Question 1:

We must solve the following quadratic equation:

[tex]x ^ 2 + 1 = 0[/tex]

We subtract 1 from both sides of the equation:

[tex]x ^ 2 + 1-1 = -1\\x ^ 2 = -1[/tex]

We apply square root to eliminate the exponent:

[tex]x = \pm \sqrt {-1}[/tex]

The solution is not real.

[tex]x_ {1} = + i\\x_ {2} = - i[/tex]

Answer:

[tex]x_ {1} = + i\\x_ {2} = - i[/tex]

Option D

Question 2:

We must solve the following quadratic equation:

[tex]x ^ 2-10x + 24 = 0[/tex]

We factor the equation, that is, we must look for two numbers that when multiplied give as result 24 and when summed with -10. These numbers are -6 and -4:

[tex]-6-4 = -10\\-6 * -4 = 24\\(x-6) (x-4) = 0[/tex]

The roots are:

[tex]x_ {1} = 6\\x_ {2} = 4[/tex]

ANswer:

[tex]x_ {1} = 6\\x_ {2} = 4[/tex]

Option D

Question 3:

We must complete squares of the following expression:

[tex]x ^ 2-18x = 7[/tex]

We add [tex](\frac {b} {2}) ^ 2 = (\frac {-18} {2}) ^ 2 = (- 9) ^ 2[/tex]

Then:

[tex]x ^ 2-18x + (- 9) ^ 2 = 7 + (- 9) ^ 2\\x ^ 2-18x + (- 9) ^ 2 = 7 + 81\\x ^ 2-18x + (- 9) ^ 2 = 88\\(x-9) ^ 2 = 88[/tex]

Then, to complete the square, add it to both sides [tex](-9) ^ 2 = 81[/tex]

Answer:

Option C

Answer:

Option B [tex]\frac{24}{25}[/tex]

Step-by-step explanation:

we know that

[tex]sin(2\theta) = 2 sin(\theta) cos(\theta)[/tex]

In this problem we have

[tex]cos(\theta)=\frac{4}{5}[/tex]

Find the value of [tex]sin(\theta)[/tex]

Remember that

[tex]sin^{2} (\theta)+cos^{2} (\theta)=1[/tex]

substitute the value

[tex]sin^{2} (\theta)+(\frac{4}{5})^{2}=1[/tex]

[tex]sin^{2} (\theta)=1-\frac{16}{25}[/tex]

[tex]sin^{2} (\theta)=\frac{9}{25}[/tex]

[tex]sin(\theta)=\frac{3}{5}[/tex]

Find the value of [tex]sin(2\theta)[/tex]

[tex]sin(2\theta) = 2 (\frac{3}{5})(\frac{4}{5})[/tex]

[tex]sin(2\theta) = \frac{24}{25}[/tex]

Answer:may 5cm

Step-by-step explanation:

Option 2 in the given figure will have a maximum volume of 5120π cubic meters.

Volume is defined as the space occupied by any object in the three-Dimensions. To find out the volume of the cylinder we need the length and diameter of the cylinder.

The volume of the first figure:-

V = ( π / 4 ) ( d² ) L

V  = ( π / 4 ) ( 10² ) 64  = 1600π cubic meters

The volume of the second figure:-

V = ( π / 4 ) ( d² ) L

V  = ( π / 4 ) ( 32² ) 20  = 5120π cubic meters

The volume of the third figure:-

V = ( π / 4 ) ( d² ) L

V  = ( π / 4 ) ( 10² ) 128  = 3200π cubic meters

We can see that the volume of the third figure is maximum.

Therefore Option 2 in the given figure will have a maximum volume of 5120π cubic meters.

Answer:

The total gain at the end of the second year for both accounts combined is $509.09.

Step-by-step explanation:

Amount saved = $8500

40% of 8500 is saved in saving account; [tex]0.4\times8500=3400[/tex]

Remainder amount in stock plan; [tex]8500-3400=5100[/tex]

Working for savings plan:

[tex]A=p(1+\frac{r}{n})^{nt}[/tex]

Here, p = 3400 ; n = 1 , t = 2 , r = 0.042

Putting values in formula:

[tex]A=3400(1+\frac{0.042}{1})^{2}[/tex]

[tex]A=3400(1+0.042)^{2}[/tex]

A = $3691.60

We get a gain of [tex]3691.60-3400=291.60[/tex] dollars

Working for stock plan:  

The stock plan decreases 3% in the first year and increases 7.5% in the second year.

[tex]5100\times 0.97=4947[/tex]

When increases;

[tex]4947\times1.075=5318.03[/tex]  dollars

So, we get a gain of [tex]5318.03-5100=218.03[/tex] dollars  

Therefore, we have a total gain of [tex]291.06+218.03=509.09[/tex] dollars.

The correct answer is first option

X = 10.53

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = opposite side/Adjacent side

From the figure we can see a right angled triangle, with one angle is  29 degree, one side is 19 and hypotenuse is x

To find the value of x

Tan θ = Opposite side/Adjacent side

Tan 29 = 19/x

x = 19 * Tan 29

 = 19 * 0.5543

 = 10.53

Therefore the correct answer is first option

Answer:

41.5 ft

Step-by-step explanation:

From the information given, and definition of midpoint, we know that:

AB = BC = ½ AC

AC = CE = ½ AE

CD = DE = ½ CE

GF = FE = ½ GE

HG = GE = ½ HE

AI = IH = ½ AH

AJ = JI = ½ AI

We also know:

AH = 20

HE = 14

GD = 4

Therefore:

AI = IH = 10

HG = GE = 7

AJ = JI = 5

GF = FE = 7/2

Next, since JB and IC are parallel with HE, we know that AJB and AIC are similar to AEH.  So:

JB / 5 = 14 / 20

JB = 7/2

IC / 10 = 14 / 20

IC = 7

And since DF and CG are parallel to AH, then DFE and DGE are similar to AHE.  So:

DF / (7/2) = 20 / 14

DF = 5

CG / 7 = 20 / 14

CG = 10

Next we know that AIB and AHC are similar, and DEG and CEH are similar.

IB / 10 = CH / 20

CH / 14 = 4 / 7

CH = 8, IB = 4.

We've found all the lengths inside triangle AEH.  Adding them up:

JB + IB + IC + CH + CG + DG + DF

7/2 + 4 + 7 + 8 + 10 + 4 + 5

41.5

The total length of the inside bars is 41.5 ft.

James is 1 meter and 63 centimeters tall

Step-by-step explanation:

James is 1 meter and 63 centimeters tall. The first step will be to subtract 1 from his height;

1.63 - 1 = 0.63 meters

The 1 subtracted is equivalent to 1 meter. The next step is to convert the remaining height in meters to centimeters by multiplying by 100;

0.63 * 100 = 63 centimeters

We can thus say, James is 1 meter and 63 centimeters tall or equivalently 163 centimeters tall
