Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Both A and B are similar but the difference is that muckrakers did not present facts to encourage more investigation, they presented facts to make a change. There are many examples but one major one is Upton Sinclair and his book "The Jungle". It exposed the meat industry and how corrupted it was. This led to many changes such as new food safety laws.

I hope this helps you:))

P.S. Might I recommend a good online calculator for these types of problems. It's called Symbolab. I use it every day and it's a lifesaver. It shows the step-by-step and has a plethora of different actions like simplifying, inverse, and line.

f • g denotes the product of f and g, so that

[tex](f\cdot g)(x)=f(x)\cdot g(x)=(3x-8)(-2x+5)[/tex]

Without computing the whole product, just look at the first terms, [tex]-6x^2[/tex]. This tells you that f • g is quadratic, and its graph is a stretched parabola that opens downward.

You can treat the product g • s similarly:

[tex](g\cdot s)(x)=(-2x+5)(4x^2-9x+2)[/tex]

The leading term is [tex]-8x^3[/tex], so the graph should resemble a stretched cubic curve reflected across the x axis.

The leading term is , so the graph should resemble a stretched cubic curve reflected across the x axis.

Answer:

-18

Step-by-step explanation:

d(1) = 1/12

d(2)=d(1) • (-6)=-1/2

d(3)=d(2)•(-6)=3

d(4)=d(3)•(-6)=-18

Answer:

43/160

Step-by-step explanation:

To find the relative frequency,

We just have to know things:

1. The data for asked event

2. Total number of data.

With these 2 points, we can create a fraction that is formed like this:

Data of event / Total data

In this case it is:

43/160

Answer:

C

Step-by-step explanation:

We start with the second line;

3x -2y + 4 = 0

3x + 4 = 2y

divide through by 2

3x/2 + 2 = y

Comparing this with standard form of y = mx + c

where m is slope

This means 3/2 is slope of the line

Since this line is perpendicular to the other line, then the product of their slopes is -1

3/2 * slope of second line = -1

Slope of second line = -1 divided by 3/2 = -2/3

We use the point slope form to find the equation of the other line

y-y1 = m(x-x1)

where m = -2/3 and (x1,y1) = (2,-3)

y-(-3) = -2/3 (x-2)

y + 3 = -2/3 (x -2)

3(y + 3) = -2(x-2)

3y + 9 = -2x + 4

3y + 5 = -2x

3y + 2x + 5 = 0

Answer:

m∠1 + m∠2 = 180°

Step-by-step explanation:

An interior angle and its exterior angle are supplementary (they add up to 180°).

Answer:

The result is 0.36b

Step-by-step explanation:

Here. we want to translate the wordings into an expression of algebra.

Firstly, we decrease b by 40%

40% is same as 40/100 = 0.4

So decreasing b by 40% = b-0.4(b) = b-0.4b = 0.6b

Now we want to decrease 0.6b by another 40%

= 0.6b -0.4(0.6b)

= 0.6b - 0.24b

= 0.36b

Answer:

[tex]profit \: percent = \frac{sp - cp}{cp} \times 100 \: percent[/tex]

where,

SP=Selling price

CP=Cost price

Given,

Selling price(SP)= 1000

Cost price(CP)=800

Now,

[tex]profit \: percent = \frac{sp - cp}{cp} \times 100 \: percent \\ = \frac{1000 - 800}{800} \times 100 \\ = \frac{200}{800} \times 100 \\ = 25 \: percent[/tex]

Hope this helps...

Good luck on your assignment..

Step-by-step explanation:

Plug in -2 whenever u see x

3(-2) -7= 5(-2-1)

-6-7= -10-1

-13 = -11

Therefore, x is not equal to -2.

Answer:

36

Step-by-step explanation:

Let's call the # of boys and girls 5x and 3x respectively. We can write:

5x = 3x + 24

2x = 24

x = 12 so the # of girls = 12 * 3 = 36

Answer:

solution,

Let the number of girls be X

Number of boys be 'x+24'

Now,

[tex] \frac{x + 24}{x} = \frac{5}{3} \\ or \: 3(x + 24) = 5x \\ or \: 3x + 72 = 5x \\ or \: 3x - 5x = - 72 \\ or \: - 2x = - 72 \\ or \: x = \frac{ - 72}{ - 2} \\ x = 36[/tex]

hope this helps..

Good luck on your assignment..

Answer:

Approximately 3.2362.

Step-by-step explanation:

Recall that definition of cosecant and sine:

[tex]\displaystyle \sin(\theta) = \frac{1}{ \csc(\theta) }\text{ and } \csc(\theta)=\frac{1}{\sin(\theta)}[/tex]

Since we are given that sin(θ) ≈ 0.3090, this means that cosecant will be:

[tex]\displaystyle \csc(\theta)\approx \frac{1}{0.3090} = 3.2362[/tex]

Answer:

3.236

Step-by-step explanation:

csc=1/sinФ

csc=1/0.3090= 3.236

Answer:

x = -45.

Step-by-step explanation:

-x - y = 30

-x - 15 = 30

x + 15 = -30

x = -45

To check we are correct...

-(-45) - y = 30

45 - y = 30

-45 + y = -30

y = 15

So, x = -45.

Hope this helps!

Answer:

x = -45

Step-by-step explanation:

-x - y = 30

Let y = 15

-x - 15 = 30

Add 15 to each side

-x-15+15 = 30+15

-x = 45

Multiply each side by -1

x = -45

Answer:

C.

Step-by-step explanation:

Slope = m = (y2 - y1)/(x2 - x1) = (5-(-1))/(4 - 2) = 6/2 = 3

Slope - point form:

y - y1 = m(x -x1)

y - 5 = 3(x - 4)

y - 5 = 3x - 12

- 3x + y = - 12 + 5

- 3x + y = - 7

Answer:

Option C is the correct option.

Step-by-step explanation:

A line passes through ( 2 , -1 ) and ( 4 , 5 )

The equation of line:

[tex] \frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1} [/tex]

Plug the values

[tex] \frac{ y - ( - 1)}{x - 2} = \frac{5 - ( - 1)}{4 - 2} [/tex]

When there is a ( - ) in front of an expression in parentheses, change the sign of each term in the expression

[tex] \frac{y + 1}{x - 2} = \frac{5 + 1}{4 - 2} [/tex]

Add the numbers

[tex] \frac{y + 1}{x - 2} = \frac{6}{4 - 2} [/tex]

Subtract the numbers

[tex] \frac{y + 1}{x - 2} = \frac{6}{2} [/tex]

Reduce the numbers with 2

[tex] \frac{y + 1}{x - 2} = 3[/tex]

Apply cross product property

[tex]3x - 6 = y + 1[/tex]

Move variable to L.H.S and change its sign

Similarly, Move constant to R.H.S and change its sign

[tex]3x - y = 1 + 6[/tex]

Add the numbers

[tex]3x - y = 7[/tex]

[tex] - 3x + y = - 7[/tex]

Hope this helps...

Question:

Found a picture which relates to the question asked. It can be found in the attachment below.

Answer:

b. c2 + b2 = a2

Step-by-step explanation:

According to Pythagoras rule :

The longest side of the triangle is the hypotenus

The opposite and adjacent sides depends on the particular angle provided or one which is to be calculated.

The opposite side is one drawn across a given angle, while the side next to the Given angle is called the adjacent side.

FROM △ABC ;

THE longest side is 'a' = hypotenus

Opposite side = c

Adjacent = b

From Pythagoras :

(Hypotenus)^2 = (Opposite)^2 + (adjacent)^2

Hence,

a^2 = c^2 + b^2

8.533333

Step-by-step explanation:

9^(− 1/ 2 )+25− 1 2 +32^ (3/ 5) = 9 (−1 /2) +25(− 1 /2) +32 ^(3 /5)

=0.333333+25^(− 1/ 2) +32 ^(3 /5)

=0.333333+25 ^(−1 /2) +32 ^(3/ 5)

=0.333333+0.2+32^ (3/ 5)

=0.533333+32 ^(3 /5)

=0.533333+8

=8.533333

Answer:

  D)  3x − 2y < 7

Step-by-step explanation:

We note that the x- and y-intercepts are about 2.3 and -3.5, respectively.

In "intercept form," the equation of the line can be written ...

  x/x-intercept +y/y-intercept = 1

Using the given intercepts, this is ...

  x/2.3 +y/(-3.5) = 1

The answer choices suggest that we should multiply this by 7. When we do, we get ...

  3x -2y = 7 . . . . the equation of the boundary line

__

The next trick is to figure the comparison symbol. We note that x-values are less than those on the line, and y-values are greater than those on the line. It is convenient to consider the term with a positive coefficient, so we don't get confused with minus signs and reversed comparisons.

As we said, x-values are less than those on the line, so the shaded area is ...

  3x -2y < 7 . . . . matches choice D
