[tex]\frac{f(x)}{g(x)}=3x^2+6x-2-\frac{12}{3x+1}[/tex]

Step-by-step explanation:

The first function is [tex]f(x)=9x^3+21x^2-14[/tex]

The second function is [tex]g(x)=3x+1[/tex].

[tex]\frac{f(x)}{g(x)}=\frac{9x^3+21x^2-14}{3x+1}[/tex]

We perform the long division as shown in the attachment to obtain the quotient as: [tex]Q(x)=3x^2+6x-2[/tex] and remainder [tex]R=-12[/tex].

5500% of 4600% is 2530

Order of Operations in Mathematics follow this following rule :

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem.

This problem is about Percentage.

Given:

What percent of 4600% is 2530?​

We can translate above questions into mathematical equation as follows:

[tex]x\% \times 4600 \% = 2530[/tex]

[tex]x\% \times \frac{4600}{100} = 2530[/tex]

[tex]x\% \times 46 = 2530[/tex]

[tex]x\% = 2530 \div 46[/tex]

[tex]x\% = \frac{55}{1}[/tex]

To convert above fraction , we could multiply with 100% :

[tex]x\% = \frac{55}{1} \times 100\%[/tex]

[tex]x\% = \boxed{ 5500 \% }[/tex]

Another Example:

50% of 4600 is 2300

80% of 4600 is 3680

100% of 4600 is 4600

120% of 4600 is 5520

Grade: Middle School

Subject: Mathematics

Chapter: Percentage

Keywords: Linear , Equations , 1 , Variable , Line , Gradient , Point , Multiplication , Division , Exponent , PEMDAS , percentange , percent

The 2530 is 55% of 46. This means that 2530 is 55% of 4600%, as 4600% is equivalent to 46 in decimal form.

To find what percent 2530 is of 4600%, we first need to understand that 4600% is equal to 46. Hence, we need to determine what percent of 46 is 2530.

Let x be the percentage we are trying to find. We can set up the equation:

x% of 46 = 2530

To solve for x, we divide both sides by 46:

x% = 2530 / 46

x% = 55

So, 2530 is 55% of 46.

To summarize, 2530 is 55% of 46. This means that 2530 is 55% of 4600%, as 4600% is equivalent to 46 in decimal form.

Step-by-step explanation:

where h is the vertical height of pyramid a is the length of base ..this formula is applicable for square based pyramid only.

Answer:

1/3 A h.

Step-by-step explanation:

The volume of a pyramid is 1/3 * area of the base * height = 1/3 A h.

So for example the area of a square-based  pyramid = 1/3 s^2 h where s is the length of a side of the square.

The equation of the circle is [tex](x+8)^{2} +(y -15)^{2} = 289[/tex].

The general equation of the circle is [tex](x-h)^{2} +(y-k)^{2} = r^{2}[/tex].

Where, (h, k) is the center and r is the radius of the circle.

Let the equation of the circle be

[tex](x-h)^{2} +(y-k)^{2} =r^{2}..(i)[/tex]

According to the given question.

The center of the circle is (-8, 15).

⇒ (h, k) = (-8, 15)

And, the circle is passing through origin i.e. (0, 0).

Since, the center of the circle is (-8, 15).

So, the equation (i) can be written as

[tex](x-(-8))^{2} +(y - 15)^{2} = r^{2}[/tex]

Also, the circle is passing through (0, 0).

Therefore,

[tex](0+8)^{2} +(0-15)^{2} = r^{2}[/tex]

[tex]\implies 64+ 225 = r^{2} \\\implies 289 = r^{2} \\\implies r=\sqrt{289} \\\implies r = 17[/tex]

So, the radius of the circle is 17 unit and its center is (-8, 15).

Therefore, the equation of the circle is

[tex](x+8)^{2} +(y-15)^{2} = 289[/tex]

Hence, the equation of the circle is [tex](x+8)^{2} +(y -15)^{2} = 289[/tex].

Answer:

(TZ - 2P)/2 = S

Step-by-step explanation:

Multiply both sides by Z

T*Z = Z*2(S + P)/Z

TZ = 2*(S + P)                    Divide by 2

TZ/2 = 2(S + P)/2              Do the division

TZ/2 = S + P                      Subtract P from both sides

TZ/2 - P = S                       That's one answer. You could refine it.

Multiply P by 2 so that you can put TZ - 2P over a common denominator.

Answer:

Something close to (1.8,2.6)

Step-by-step explanation:

y=2x-1

y=-1/4 x+3

Since y=2x-1 and y=-1/4 x +3 then 2x-1=-1/4 x +3.

I'm going to multiply both sides by 4 to get rid of the fraction:

8x-4=-x+12

Add x on both sides:

9x-4=12

Add 4 on both sides:

9x=16

Divide both sides by 9:

x=16/9 is approximately 1.8 when put into calculator.

Now if x=16/9 and y=2x-1, then y=2(16/9)-1=32/9-1=32/9-9/9=(32-9)/9=23/9.

y=23/9 is approximately 2.6 when put into calculator.

Answer:

Option 1 is correct. i.e  2 hours walking; 12 hours running

Step-by-step explanation:

We are given the equations

3w + 6r ≥ 36

3w + 6r ≤ 90

We will check which of the option satisfy the above equations.

1)  2 hours walking; 12 hours running

w = 2 and r =12

3w + 6r ≥ 36

3(2) + 6(12) ≥ 36

6+72 ≥ 36

78 ≥ 36

3w + 6r ≤ 90

3(2) + 6(12) ≤ 90

6+72 ≤ 90

78 ≤ 90

Both equations are satisfied. Option 1 is correct.

2) 4 hours walking; 3 hours running

w = 4 and r =3

3w + 6r ≥ 36

3(4) + 6(3) ≥ 36

12+18 ≥ 36

30 ≥ 36 (this equation doesn't hold as 30 < 36 and not < or equal to 36)

3w + 6r ≤ 90

3(4) + 6(3) ≤ 90

12+18 ≤ 90

30 ≤ 90

So, Option 2 is incorrect.

3) 9 hours running 12 hours walking

w = 9 and r =12

3w + 6r ≥ 36

3(9) + 6(12) ≥ 36

27+72 ≥ 36

99 ≥ 36

3w + 6r ≤ 90

3(9) + 6(12) ≤ 90

27+72 ≤ 90

99 ≤ 90 (this equation doesn't hold because 99 is greater than 90 and not less than 90)

Option 3 is incorrect.

4) 12 hours walking; 10 hours running

w = 12 and r =120

3w + 6r ≥ 36

3(12) + 6(10) ≥ 36

36+60 ≥ 36

96 ≥ 36

3w + 6r ≤ 90

3(12) + 6(10) ≤ 90

36+60 ≤ 90

99 ≤ 90 (this equation doesn't hold because 96 is greater than 90 and not less than 90)

Option 4 is incorrect.

Answer:

A large pizza costs $5 and a small pizza costs $3.

Let 'x' be the number of large pizzas and 'y' the number of small pizzas. We have that:

x + y = 150

5x + 3y = 570

Solving the system of equations:

x + y = 150 → 3x + 3y = 450 → 3y = 450 - 3x

5x + 3y = 570 → 5x + 450 - 3x = 570

2x = 120

x = 60

y = 150 - 60 = 90

Therefore. Carmen y Carlos will make 60 large pizzas and 90 small pizzas.

Answer:

Acute triangle

Step-by-step explanation:

A isosceles triangle is a triangle that has two equal sides.

It would not be a scalene triangle because in scalene triangles all the sides have different lengths.

It might be an acute triangles because all the angles in an acute triangle would be acute angles.

it wouldn't be an obtuse triangle because in an obtuse triangle there is at least one obtuse angle and the other 2 angles would be either acute, right, or obtuse.

It could be an isosceles triangle but that wouldn't make sense since its already an isosceles triangle.

Answer:

c = sqrt( 29x^2 + 44x + 52)

Step-by-step explanation:

This is an application of the Pythagorean theorem

c = sqrt(a^2 + b^2)

a = 2x - 4

b = 5x + 6

c = sqrt( (2x - 4)^2 + (5x + 6)^2 )                           Substitute and expand

c = sqrt( 4x^2 -  16x + 16 + 25x^2 + 60x + 36)     Collect like terms

c = sqrt( 4x^2 + 25x^2 - 16x + 60x + 16+36)        Combine the like term pairs.

c = sqrt( 29x^2 + 44x + 52)

This does not factor into anything very nice.

Answer:

Madeline is standing 2x - 4 feet from the base of a tree, and the height of the tree is 5x + 6

Now we want to know the distance from Madeline's feet to the top of the tree.

You could picture it as a triangle rectangle, where the cathetus is the distance between Madeline and the tree and the distance between the floor and the top of the tree, in this case the distance between Madeline's feet and the top of the tree is the hypotenuse of such triangle rectangle, and can be obtained using the Pythagorean theorem: "the square of the hypotenuse is equal to the sum of the square cathetus"

then:

[tex]H^2 = (2x - 4)^2 + (5x + 6)^2[/tex]

[tex]H^2 = (4x^2 -16x + 16) + (25x^2  + 60x +36)[/tex]

[tex]H^2 = (29x^2 + 44x + 52)[/tex]

[tex]H = \sqrt{ (29x^2 + 44x + 52)}[/tex]

this is the distance from Madeline's feet to the top of the tree in terms of x.

When a matrix is multiplied by its inverse the result will be the identity matrix. If we multiply two matrix with the same size, the resulting matrix will have the same dimension.

Therefore, if we multiply the matrices X and Y we will get a 2x2 identity matrix, as follows:

[tex]\left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right][/tex]

Answer:

[tex]\left[\begin{array}{ccc}1&0\\0&1\end{array}\right][/tex]

Step-by-step explanation:

We are asked find the matrix that represent the product of matrices X and Y both measures [tex]2\times 2[/tex] and inverse of each other.

For a matrix multiplication to be defined, the number of columns in the first matrix must be equal to number of rows in the second matrix.

Since the both matrices are [tex]2\times 2[/tex] (same number of column and row), then the product of both matrices would result in [tex]2\times 2[/tex] matrices.

We also know that the multiplication of a matrix with its inverse results in identity matrix.

Therefore, our matrix would be a [tex]2\times 2[/tex] identity matrix as:

[tex]\left[\begin{array}{ccc}1&0\\0&1\end{array}\right][/tex].

Answer:

tan O = √3/ 3.

Step-by-step explanation:

The tangent is  positive in quadrant 3.

The adjacent side has length  √((2^2 - (-1)^2)

= -√3.

So tan O  = -1 / -√3

= 1 / √3

= √3/ 3.

To determine tan(θ) for an angle θ where sin(θ) = -1/2 and θ is in quadrant III, we perform the following steps:
1. **Understand the given information:** When sin(θ) = -1/2, it means the opposite side to angle θ in a right triangle is -1 and the hypotenuse is 2. Since θ lies in the third quadrant, both sine and cosine values are negative, implying that the adjacent side length must also be negative.
2. **Use the Pythagorean theorem:** For a right triangle:
  \[ \text{hypotenuse}^2 = \text{opposite}^2 + \text{adjacent}^2 \]
  Substituting hypotenuse and opposite side values:
  \[ 2^2 = (-1)^2 + \text{adjacent}^2 \]
  Simplify and solve for the adjacent side:
  \[ 4 = 1 + \text{adjacent}^2 \]
  \[ 3 = \text{adjacent}^2 \]
  \[ \text{adjacent} = \sqrt{3} \] or \[ \text{adjacent} = -\sqrt{3} \]
  Since the angle is in the third quadrant where cosine is also negative, we must take the negative square root:
  \[ \text{adjacent} = -\sqrt{3} \]
3. **Calculate tan(θ):** By definition,
  \[ \tan(θ) = \frac{\text{opposite}}{\text{adjacent}} \]
  Substitute the known side lengths:
  \[ \tan(θ) = \frac{-1}{-\sqrt{3}} \]
4. **Simplify the expression:**
  \[ \tan(θ) = \frac{1}{\sqrt{3}} \]
  To rationalize the denominator:
  \[ \tan(θ) = \frac{1}{\sqrt{3}} \times \frac{\sqrt{3}}{\sqrt{3}} \]
  \[ \tan(θ) = \frac{\sqrt{3}}{3} \]
Thus, if sin(θ) = -1/2 and θ is in quadrant III, then tan(θ) = √3/3. Note that in the context of trigonometry, it is often assumed that the angle and the ratios are dimensionless, so a negative 'opposite' simply reflects the direction along the coordinate axis rather than a literal negative length.

Answer:

The correct option is A

Step-by-step explanation:

The expression is

2y3 - 27 + 5y2 + (25 / 5)

Substitute the value of y=2 in the expression:

=2(2)³-27+5(2)²+(25/5)

We know that 2³ means multiply 2 three times

2³= 2*2*2=8

Likewise 2²=2*2=4

=2(8)-27+5(4)+(25/5)

=16-27+20+25/5

Now take the L.C.M which is 5

=80-135+100+25/5

Solve the values in the numerator:

=70/5

=14

Thus the correct option is A....

The equation for the situation where Carla withdraws $7 and is left with an $89 balance is: B - $7 = $89. So Carla's initial balance was $96.

When writing an equation based on the statement that after withdrawing $7 from a checking account, Carla’s balance was $89, we are essentially working out what Carla's balance was before she made the withdrawal.

If we let the variable B represent Carla's initial balance, then after she withdraws $7, her new balance is B - $7.

Since it's given that her balance after the withdrawal is $89, we can write the following equation to represent the situation:

B - $7 = $89

To find the value of B, we would add $7 to both sides of the equation, which would give us:

B = $89 + $7

B = $96

So, Carla's initial balance before the withdrawal was $96.

Answer:

b=2

Step-by-step explanation:

9x + 12y = 21

6x + 8y = 7b

To have an infinite number of solutions, the two equations must be equal

Take the first equation and divide by 3, since it is a factor of all the terms

9x/3 + 12y/3 = 21/3

3x+4y = 7

Then multiply by 2 to get the x term equal

2*3x + 2*4y = 2*7

6x +8y = 7*2

Comparing this to the second equation

6x + 8y = 7b

b must equal 2
