Answer:

-3c

Step-by-step explanation:

The given expression is:

[tex]\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}}[/tex]

We need to simplify this expression. The rational expression in the denominator can be multiplied to numerator by taking its reciprocal as shown below:

[tex]\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}} \\\\ =\frac{6c^{2}+3c}{-4c+2} \times \frac{4c-2}{2c+1}\\\\=\frac{3c(2c+1)}{-(4c-2)} \times \frac{4c-2}{2c+1}\\\\ =-3c[/tex]

Thus, the given expression in simplified form is equal to -3c

Answer:

-3c

Step-by-step explanation:

We are given that an expression

[tex]\frac{\frac{6c^2+3c}{-4c+2}}{\frac{2c+1}{4c-2}}[/tex]

We have to find an expression which is equal to given  expression

Taking common 3c from nominator and -2 from denominator in dividened  and 2 common in divisor then we get

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

[tex]\frac{3c(2c+1)}{-2(2c-1)}\times \frac{2(2c-1)}{(2c+1)}[/tex]

By reciprocal divisor

By canceling same factor

Then ,we get

[tex]\frac{\frac{6c^2+3c}{-4c+2}}{\frac{2c+1}{4c-2}}[/tex]

Answer:

The function reveals that the maximum earning from ticket sales will be $6480 after 2 ($0.50) price increases

Step-by-step explanation:

* Lets explain how to solve the problem

- The function f(x) = -20x² + 80x + 6400 represents the total

 earnings from ticket sales and x represents the number of $0.50

 price increases

∵ f(x) is a quadratic function

∵ The coefficient of x² is -20

∴ The function has a maximum value

- The vertex of the quadratic function f(x) = ax² + bx + c is (h , k),

 where h = -b/2a and k = f(h)

* Lets find the maximum point of f(x)

∵ a = -20 , b = 80

∵ h = -b/2a

∴ h = -(80)/2(-20) = -80/-40 = 2

∵ k = f(h) and h = 2

∴ f(2) = -20(2)² + 80 (2) + 6400

∴ f(2) = -80 + 160 + 6400

∴ f(2) = 6480

∴ k = 6480

* The function reveals that the maximum earning from ticket sales

  will be $6480 after 2 ($0.50) price increases

Answer:

maximum, 6480, two

The probability of an event and its complement add up to 1. If the probability of an event is 0.3, the probability of its complement is 0.7.

The probability of an event and its complement always add up to 1. So, if the probability of an event is 0.3, the probability of its complement can be calculated by subtracting the probability of the event from 1. In this case, the probability of the complement would be 1 - 0.3 = 0.7. Therefore, the probability of the complement is 0.7.

Answer:

135°

Step-by-step explanation:

To convert from radian measure to degree measure

degree measure = radian measure × [tex]\frac{180}{\pi }[/tex], so

degree = [tex]\frac{3\pi }{4}[/tex] × [tex]\frac{180}{\pi }[/tex]

Cancel π on numerator/denominator and 4, 180 by 4, leaving

degree = 3 × 45 = 135°

Answer:

1 radian = 180 / PI degrees

3 PI / 4 radians * 180 / PI the "PI's" cancel and we get

3 / 4 * 180 = 135 degrees

Answer:

6x + 8 = 32

Step-by-step explanation:

Let the number be= x

So 6 times a certain number is added to 8 which gives the answer 32.

6( x ) + 8 = 32

6x + 8 = 32

Hence this is the equational form.

On further solving we get,

6x = 32 - 8

6x = 24

x = 24 / 6

x = 4....

Answer:

The required equation is 6x+8=32

Step-by-step explanation:

Consider the provided information.

6 times a certain number is added to 8, the result is 32

Let the number is represents by x.

6 times of a number can be written as: 6x

Add 8 to the above expression.

6x+8

The expression is equal to 32.

Thus, the required equation is 6x+8=32

Answer:

The mass of 150 books = 41.7kg

The number of books that have mass 20kg = 72 books

Step-by-step explanation:

(I) Number of identical books = 108

Mass of  books = 30 kg

Mass of 150 books = ?

Let the mass of 150 books = x kg

To find the mass of 150 books we will use ratio and proportion:

108 books: 30kg = 150 books: x kg

You can also write it like this because ratio can be written in division:

108/30 = 150/x

By cross multiplication:

108x = 150*30

108 x= 4500

Divide both sides by 108

108 x/108 = 4500/108

x= 41.7

Thus the mass of 150 books = 41.7kg

( ii ) The number of books that have a mass of 20 kg = ?

Let assume that the number of books of mass 20 kg = y books

We will again use ratio and proportion method.

108 books: 30kg = y: 20kg

We can write it as:

108/30 = y/20

By cross multiplication:

108 *20 = 30y

2160= 30y

Divide both the terms by 30

2160/30 = 30y/30

72 = y

Therefore the number of books that have mass 20kg = 72 books ....

A p e x

Answer:212.5

Step-by-step explanation:85/100×250

=212.5

85 percent of 250 results in 212.5.

To find 85 percent of 250, follow these steps:

Change the percentage to a decimal by dividing by 100: 85% = 85 / 100 = 0.85

Multiply the decimal by the number: 0.85 x 250

Calculate the product: 0.85 x 250 = 212.5

Therefore, 85 percent of 250 is 212.5.

For example, if 250 students are surveyed, then 212.5 students would represent 85 percent of the surveyed group.

Answer:

C; The left end goes up; the right end goes down

Step-by-step explanation:

If you expand the function, you end up with a polynomial with a negative coefficient and it has an odd power. According to polynomial behaviors of a function that is odd negative, the graph will rise to the left (y → ∞ and x → -∞) and falls to the right (y → -∞ and x → ∞).

ANSWER

C. The left end goes up; the right end goes down.

EXPLANATION

The given function is

[tex]f(x) = - 2( {x - 2)}^{5} [/tex]

We analyze the end behavior of this function using the leading term.

The leading term of this function is:

[tex] - 2 {x}^{5} [/tex]

Since the degree(5) is odd and the leading coefficient (-2) is negative, the graph rises on the left and falls on the right.

In other words, the left end of the graph goes up and the right end goes down.

The correct option is C.

Answer:

Up down and side to side on the graph

Step-by-step explanation:

If a is 1, since it is positive the parabola moves up. If a is -1, since it is negative the parabola moves down. (not sure about side to side because I can't back that one up but I'm 100% sure about up and down)

When a is between 0 and 1, the parabola gets wider.

A parabola is a mathematical curve that is defined by a point and a line. The point is known as the focus, and the line is called the directrix. The parabola has the property that all points on it are equidistant from the focus and the directrix.

Here,

When a is negative, the parabola flips 180°.

When |a| is less than 1, the parabola opens wider.

When |a| is greater than 1, the parabola opens more narrow.

When a is between 0 and 1, the parabola gets wider, when it is greater than 1, it gets narrower, and when it is less than 0 it is reflected across the x-axis.

Therefore, when a is between 0 and 1, the parabola gets wider.

The correct option is b). The statement is False, it incorrectly describes the method for converting minutes to seconds.

To convert minutes to seconds, you multiply by 60 because there are 60 seconds in one minute.

So, to convert 5.25 minutes to seconds:

[tex]\[ 5.25 \text{ minutes} \times 60 \text{ seconds/minute} = 315 \text{ seconds} \][/tex]

Therefore, 5.25 minutes is equal to 315 seconds.

Regarding your original question about the statement:

To convert 5.25 minutes to seconds, you would use the ratio  [tex]\( \frac{1 \text{ second}}{60 \text{ minutes}} \).[/tex]

This statement suggests using a ratio, which is not correct for converting minutes to seconds. Instead, you should use multiplication by 60 seconds per minute.

The radius is the distance from the center of the circle to its edge.

The diameter is the distance from one point on the edge to the opposite point on the edge, so it is twice as much as the radius.

Answer:

(-12, 0) and (5, 0)

Step-by-step explanation:

f(x) = x² + 7x − 60

Here, a = 1, b = 7, c = -60.  Using the AC method, we need to find factors of a×c that add up to b.

12 × -5 = -60

12 + -5 = 7

The factors are 12 and -5.

f(x) = (x + 12) (x − 5)

The zeros are:

x + 12 = 0, x − 5 = 0

x = -12, x = 5

The zeros are (-12, 0) and (5, 0).

[tex]x^2+7x-60 =0\\x^2-5x+12x-60=0\\x(x-5)+12(x-5)=0\\(x+12)(x-5)=0\\x=-12 \vee x=5[/tex]

Answer:

Therefore we have:

[tex]log_{7}7 - 2log_{7}x[/tex]

→ [tex]log_{7}7 - log_{7}x^{2}[/tex]

→ [tex]log_{7} \frac{7}{x^{2} }[/tex]

The solution is: [tex]log_{7} \frac{7}{x^{2} }[/tex]
