Answer:

New coordinates:

A = (-2, 1)

B = (0, 1)

C = (2, -3)

D = (0, -3)

Step-by-step explanation:

First, determine the ordered pairs for ABCD.

A = (2, 4)

B = (4, 4)

C = (6, 0)

D = (4, 0)

Horizontal movement will only affect the x coordinates of the ordered pairs. Horizontal movement includes moving to the right and left.

Vertical movement will only affect the y coordinates of the ordered pairs. Vertical movement includes moving up and down.

The question asks us to translate 4 units to the left. Moving left on the graph means we will subtract 4 from the x coordinates. The question also asks us to translate 3 units down. Moving down also means subtraction, but from the y coordinate.

New A = (2 - 4, 4 - 3) = (-2, 1)

New B = (4 - 4, 4 - 3) = (0, 1)

New C = (6 - 4, 0 - 3) = (2, -3)

New D = (4 - 4, 0 - 3) = (0, -3)

The new translation will have A at (-2, 1), B at (0, 1), C at (2, -3), and D at (0, -3).

Answer:

1.5 pounds of beans are in each nag

Solution :

It is given that the distance between the two lights is 30 feet.

The angle of elevation of the upper light from the boat, ∠ ABP = 32 degree

The angle of elevation of the lower light from the boat, ∠ ABQ = 14 degree

∴ ∠ PBQ = ∠ ABP - ∠ ABQ

              = 32 - 14

              = 18 degree

In triangle PAB

∠ PAB = 180 - (90 + 32)

           = 58 degree

Similarly in triangle AQB

∠ AQB = 180 - (90 + 14)

           = 76 degree

Now considering triangle PBQ and applying the sine theorem,

[tex]$\frac{PQ}{\sin 18}=\frac{BQ}{\sin 58}$[/tex]

we know PQ = 30 feet

∴ [tex]$BQ =\frac{\sin 58}{\sin 18} \times 30$[/tex]

        = 82.33 feet

Again taking the right triangle ABQ and applying sine theorem,

[tex]$\frac{BQ}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

[tex]$\frac{82.33}{\sin 90}=\frac{AB}{\sin 76}$[/tex]

∴ [tex]$AB = 82.33 \times \sin 76$[/tex]

         = 79.88 ft

         = 80 feet

Answer: 3

Answer: 35

Step-by-step explanation:

Answer:

Option C represents an exponential function

Step-by-step explanation:

Generally, we have an exponential function in the form ;

y = a.b^x

Where in fact, a is not 0

In this case, let us have a as 1 and b as 2

So we have;

for x = -1

y = 2^-1 = 1/2

for x = 0

y = 2^0 = 1

for x = 1

y = 2^1 = 2

for x = 2

y = 2^2 = 4

So the correct choice here is the third option

Answer:

According to the model, in 2025 the world population will be 8,493,750,000

Step-by-step explanation:

Rate at which population was growing per year = 0.09125 billion

Initial population figure in 1990 = 5.3 billion

World population prediction in 2010 ;

Predicted population figure :

Initial population + (population growth value per year * number of years)

number of years = (2025 - 1990) = 35 years

Predicted population figure in 2025 :

5.3 + (0.09125 * 35)

5.3 + 3.19375

= 8.49375 billion.

8,493,750,000 by 2025

Statement B and statement D are true

Step-by-step explanation:

A game has green and blue pieces. The ratio of

green game pieces to total pieces is 5:12.

Select all the statements that are correct about the game pieces.

A. The ratio of green pieces to blue pieces is 7:5.

B. The ratio of total pieces to blue pieces is 12:7,

C. There must be 7 more blue pieces than green pieces.

D. The ratio of total pieces to green pieces is 12:5.

Ratio of green pieces = 5

Ratio of total pieces = 12

Ratio of blue pieces = Ratio of total pieces - Ratio of green pieces

= 12 - 5

= 7

Ratio of blue pieces = 7

A. The ratio of green pieces to blue pieces is 7:5.

Green pieces : blue pieces = 5 : 7

A is not true

B. The ratio of total pieces to blue pieces is 12:7

Total pieces : blue pieces = 12 : 7

B is true

C. There must be 7 more blue pieces than green pieces.

Blue = 7

Green = 5

There are 2 more blue pieces than green pieces

C is not true

D. The ratio of total pieces to green pieces is 12:5

Total pieces : green pieces = 12 : 5

D is true

5/6+1/15+1/12in on minute

Emma's best record is 59/60 kilometers per minute.

Given that, Emma personal record was 5/6 of a kilometer in one minute.

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Given, after six months, she improved her record by 1/15 of a kilometer. After a year, she further improved her record by 1/12 of a kilometer.

Now, 5/6 + 1/15 + 1/12

LCM of denominators 6, 15 and 12 is 60.

50/60 + 4/60 + 5/60

= 59/60

Therefore, Emma's best record is 59/60 kilometers per minute.

Answer:

27

Step-by-step explanation:

1. Using PEMDAS, you would start with all numbers inside the parentheses

2. Next inside the parentheses are exponents

3² = 3*3 = 9

2³ = 2*2*2 = 4*2 = 8

2² = 2*2 = 4

3. Go back inside the parenthese now that everything is multiplied out

[tex]\frac{9 *(8+4) }{4}[/tex] = 9* ( 12)/4 = 108/4

4. Simplify the fraction by dividing 108 by 4

108 ÷ 4 = 27

The rectangular form of the given equation r= 2 / 7sinθ−cosθ which is in polar form is  7x - y = 2 and the slope-intercept form is y = 7x - 2

To convert from polar form to rectangular form we simply take the following steps:

The slope-intercept form is,

y = mx +c

where m is the slope made and c is the intercept both made by the straight line.

In the given question let's first rearrange it,

r × (7sinθ − cosθ) = 2

Multiplying the term (7sinθ−cosθ) with r we get,

7rsinθ - rcosθ = 2

Now we will follow the steps discussed above which is we will put x and y respectively in place of rsinθ and rcosθ.

7x - y = 2

So, the slope-intercept form will be,

y = 7x - 2

Therefore, the rectangular form is 7x - y = 2 and the slope-intercept form is y = 7x - 2.

The slope of the line as shown in the graph of the linear function in the image below is: negative.

The slope of a line of a linear function = change in y/change in x.

The value of the slope would be positive if the graph increases upwards from your left to your right.

The value of the slope would be negative if the graph decreases downwards from your left to your right.

Thus, the slope of horizontal lines are always zero while the slope of vertical lines are undefined.

Therefore, the slope of the line as shown in the graph of the linear function in the image below is: negative.

Answer:

when using elimination you "eliminate one variable by adding the equations", so basically in this equation 2y-2y cancel out when you add the equations together. so, you'll find x first. once you find the value of x, then you plug x into one of the equations to find the ordered pair solution, which happens to be (-1,0) in this solution.

Answer:

There are 12 6th graders

Step by Step Explanation:

Because there are 28 students, you have to make a fraction wuth a denominator of 28. To do that, you have to multiply the denominator of 3/7 by 4 to get 3/28. To get an equivalent fraction, you need to multiply the numerator by 4 too, because whenever you do something to the denominator of a fraction, you must mirror it for the numerator and vice versa. so 3/7 × 4 equals 12/28. So 12 out of the 28 students are 6th graders.
