Answer:

f(g(x)) = 72x^2+1

Step-by-step explanation:

f(x) = 2x^2 +1

g(x) = -6x

f°g(x) means f(g(x))

Take g(x) and substitute it in for x in f(x)

f(g(x)) = 2(g(x))^2 +1

           =2(-6x)^2 +1

          =2(36x^2) +1

           =72x^2 +1

Answer:

[tex]-\frac{4m^{4}n^{2}}{9}[/tex]

Step-by-step explanation:

The given expression is

[tex]=\frac{(2m^3n^2)^3}{-18m^5n^4}[/tex]

Use the power rule of indices on the denominator;[tex](a^m)^n=a^{mn}[/tex]

[tex]=\frac{8m^9n^6}{-18m^5n^4}[/tex]

We apply the quotient rule of indices; [tex]\frac{a^m}{a^n} =a^{m-n}[/tex]

[tex]=\frac{8m^9n^6}{-18m^5n^4}[/tex]

[tex]=-\frac{4m^{9-5}n^{6-4}}{9}[/tex]

Simplify

[tex]=-\frac{4m^{4}n^{2}}{9}[/tex]

Answer:

The correct answer is

(2m³n²)³/(-18m⁵n⁴) = - m⁴n²/9

Step-by-step explanation:

It is given an expression,

(2m³n²)³/(-18m⁵n⁴)

Points to remember

Identities

1).  (xᵃ)ᵇ  =  xᵃᵇ

2).  xᵃ/xᵇ = xᵃ⁻ᵇ

To solve the expression

(2m³n²)³/(-18m⁵n⁴) = -2m⁹n⁶/18m⁵n⁴    (Using identity 1)

 = -2/18(m⁹⁻⁵n⁶⁻⁴)     (Using identity 2)

 = -1/9(m⁴n²)

 = - m⁴n²/9

Therefore the simplified form of given expression is given by,

(2m³n²)³/(-18m⁵n⁴) = - m⁴n²/9

What are four common denominators for 1/4 & 1/2

Answers

I am pretty sure that it is 8,12,16 and 20

if not plz forgive me

The common denominators for 1/4 and 1/2 are:

8421

These denominators are found by identifying the multiples of the denominators of 1/4 and 1/2.

The question at hand involves finding four common denominators for the fractions 1/4 and 1/2. A common denominator is a shared multiple of the denominators of two or more fractions. This task is essential for operations like addition, subtraction, or comparison of fractions.

4: This is the most obvious choice since 4 is the denominator of one of the fractions, and 2 is a factor of 4. Hence, 1/2 can be expressed as 2/4.

8: Doubling the first common denominator gives us 8. In this case, 1/4 becomes 2/8 and 1/2 is 4/8.

12: Multiplying the denominators 4 and 2 gives us another common denominator, 12. Thus, 1/4 can be expressed as 3/12 and 1/2 as 6/12.

20: Choosing a higher number that is divisible by both 4 and 2. Here, 1/4 is 5/20 and 1/2 becomes 10/20.

These examples show how to scale the numerators accordingly to maintain the value of the original fractions while having the same denominator.

20) Use the distributive property to factor the expression. 10xz − 20yz
A) z(10x − 20y)
B) 10(xz − 2yz)
C) 10z(x − 2y)
D) xyz(10 − 20)

Answers

Answer:

C. 10z(x - 2y)

Step-by-step explanation:

10xz − 20y

Factor the terms

Factors of   10xz =          2 ×      5 × x ×        z

Factors of -20yz = (-1) × 2 × 2 × 5 ×       y × z

Identify their greatest common  factor

The common factors are 2, 5, and z. The greatest common  factor is 10z.

Rewrite them with the GCF as a factor

 10xz = 10z ×      x

-20yz = 10z × (-2y)

Replace the terms in the original expression with the factored terms

10xz − 20yz = 10z(x) + 10z(-2y)

Use the distributive property to isolate the greatest common factor

10z(x) + 10z(-2y) = 10z(x - 2y)

Answer:

C. 10z(x - 2y)

ABEF=CBED. The perimeter of CBED is 17. Find the length of BE

Answers

2.7. Because of the CPCTC theorem, like CB is equal to 5.9 so if you add the lengths of CB, CD, and ED and subtract this by 17, you find the length of BE which is 2.7

Answer:

Option B, 2.7 is the answer.

Step-by-step explanation:

Perimeter of CBED = CD + ED + BC + BE

                         17   =  5.6 + 2.8 + 5.9 + BE

[Since ABEF ≅ CBED  so  AB = BC = 5.9]

Now      17   =  14.3 + BE

             BE =  17 - 14.3

                 = 2.7

Therefore, Length of BE = 2.7

Option B, 2.7 is the answer.

In the same circle, chord AB determines a 115° arc and chord AC determines a 43° arc. Find m∠BAC.

Answers

Answer:

36° or 101°

Step-by-step explanation:

Consider the figures given in the attachment.

Point C can be between A and B as shown in the left image of the attachment or outside AB chord as shown in the right image.

In both figures, ∠AOB = 115° and ∠AOC = 43°.

Both the triangles are isoceles triangle as OC and OA side is equal in ΔAOC and OA and OB is equal in ΔAOB.

In ΔAOC,

∠A + ∠O + ∠C = 180°

∠A = ∠C

∴ 2 ∠A =180-43=137°

∴∠A = 68.5

In ΔAOB,

∠A + ∠B + ∠O = 180°

∠A = ∠B

∴2 ∠A = 180-115=65°

∴∠A = 32.5°

For figure on the left side,

∠BAC = ∠OAC - ∠OAB = 68.5 - 32.5 =36°

For figure on right side,

∠BAC = ∠OAC + ∠OAB = 68.5 + 32.5 =101°

if it takes 5 men 20hours to brick a house, how long will it take 2 men to do the job if they work at the same rate?

Answers

To find the contribution of each man (this is a sexist problem as women could work as well, but that’s besides the point) take 5/2 and then multiply that value by 20 and you’ll find it takes 50 hours for two men to do it.

Answer: 50 hours

Answer:

50 hours.

Step-by-step explanation:

To solve these type of question we should always remember that man power is inversely proportionate to the work done.

That means if we double the manpower work done will be half. and when we reduce the manpower to the half time take to complete the work will be double.

It takes 5 men to brick a house = 20 hours

so 1 man will brick the house = 20 × 5

                                                = 100 hours

Therefore, 2 men will brick the house =  [tex]\frac{100}{2}[/tex]

                                                               = 50 hours.

What is the percent of decrease from 10 to 3?
Write your answer using a percent sign (%).

Answers

Final answer:

The percent of decrease from 10 to 3 can be calculated by finding the difference between the two numbers, dividing this difference by the original number, and multiplying the result by 100. This method gives us a decrease of 70%.

Explanation:

The question is looking to find the percent of decrease between two numbers, specifically from 10 to 3. To calculate this, we first find the difference between the two numbers (which is 10 - 3 = 7), then divide this difference by the original number (7 divided by 10 equals 0.7) and finally multiply the result by 100 to convert it to percentage form. This gives us a 70% decrease.

Here are the step-by-step calculations:

Find the difference between the two numbers: 10 - 3 = 7.Divide the difference by the original number: 7 / 10 = 0.7.Multiply the result by 100 to convert to a percentage: 0.7 x 100 = 70%.

So, the decrease from 10 to 3 is 70%.

It simplifies to 17x + 36y + 5.

Step-by-step explanation:

In this situation, there are four different items being purchased. This means their will be a sum of 4 terms. Each term will be the number of the item times its cost. When added together, the four terms will represent the total cost.

7 pens at $x is 7x

5 pens at $(2x+3) is 5(2x+3)

y pens at $6 is 6y

(3y-1) pens at $10 each is 10(3y-1)

All together the cost expression is 7x + 5(2x+3) + 6y + 10(3y -1).

Simplify by applying the distributive property and combine like terms.

[tex]y = 3x - 3[/tex]

EXPLANATION

Let

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

be the equation.

We can choose any two ordered pairs to determine the equation of the relation.

[tex](6,15) \: and \: (8,21)[/tex]

We find m using the formula;

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

[tex]m = \frac{21 - 15}{8 - 6} = \frac{6}{2} = 3[/tex]

The equation becomes

[tex]y = 3x + c[/tex]

When x=6, y=15.

This implies that,

[tex]15 = 3(6) + c[/tex]

[tex]15= 18 + c[/tex]

[tex]15 - 18= c[/tex]

[tex]c = -3[/tex]

If y = 2x - 1 and (3, 5) and (4, 7) are part of the pattern then what is the y coordinate of (5, __ )? A) 8 B) 9 C) 10 D) 11

Answers

Answer:

(5, 9)

Step-by-step explanation:

Substitute the x- coordinate of the point into the equation to evaluate the y- coordinate, that is

x = 5 : y = (2 × 5 ) - 1 = 10 - 1 = 9 → B

Hence the coordinates of the point are (5, 9 )

Final answer:

Using the equation y = 2x - 1, the y-coordinate for the point (5, __) is calculated to be 9 by substituting x = 5 into the equation, resulting in the value that fits the identified pattern.

Explanation:

The question asks for the y-coordinate of the point (5, __) based on the pattern described by the equation y = 2x - 1. We see that the given points (3, 5) and (4, 7) fit this pattern, as plugging x = 3 into the equation gives y = 2(3) - 1 = 5, and plugging x = 4 into the equation gives y = 2(4) - 1 = 7. To find the y-coordinate for the point where x = 5, we can follow the same arithmetic pattern.

Using the equation, we plug in x = 5:

y = 2(5) - 1
= 10 - 1
= 9

Therefore, the y-coordinate for the point (5, __) is 9, which corresponds to option B.

In ΔVWX, the measure of ∠X=90°, XV = 27 feet, and WX = 57 feet. Find the measure of ∠V to the nearest degree.

Answers

Answer:

[tex]<V=65\°[/tex]

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle VWX

[tex]tan(V)=\frac{WX}{XV}[/tex] -----> opposite side angle V divided by the adjacent side angle V

substitute the values

[tex]tan(V)=\frac{57}{27}[/tex]

[tex]<V=arctan(\frac{57}{27})=65\°[/tex]

Final answer:

To find the measure of ∠V, we take the ratio of XV to WX (opposite to adjacent side) and use the tangent function. By calculating tan(∠V) = 27/57 and taking the inverse tangent, we get ∠V ≈ 25° to the nearest degree.

Explanation:

To find the measure of ∠V in ∆VWX, where ∠X=90°, XV = 27 feet, and WX = 57 feet, we use the trigonometric ratios, specifically the tangent function, since we are dealing with a right-angled triangle and we have the lengths of the opposite side (XV) and the adjacent side (WX) to ∠V.

Step by Step Solution:

Use the definition of the tangent function: tan(∠V) = opposite/adjacent.

Substitute the known values: tan(∠V) = XV/WX = 27/57.

Calculate tan(∠V) = 0.4737.

Find the angle whose tangent is 0.4737 using an inverse tangent function on a calculator: ∠V ≈ 25° (to the nearest degree).

Therefore, the measure of ∠V is approximately 25°.
