The coordinates of endpoint B are (-7, 11)

From the question, we are to determine the coordinates of the endpoint B

If the coordinates of the endpoints of a line, AB, are A(x₁, y₁) and B(x₂, y₂), then the coordinates of the midpoint is given by

((x₁+x₂)/2, (y₁+y₂)/2)

From the given information,

The coordinates of A are (3, 7) and the coordinates of the midpoint are (-2, 9)

Let the coordinates of endpoint B be (x, y)

Then,

(3+x)/2 = -2

3 +x =-4

x = -4 -3

x =  -7

and

(7 + y)/2 = 9

7 + y = 18

y = 18 - 7

y = 11

Hence, the coordinates are (-7, 11)

[tex]19\%[/tex]

Percentages are evaluated values that say how much of a whole is occupied by that value. For example, if we were to say 75% of a strawberry pie remained, we could also see this as 3/4, or three-fourths.

To solve this particular problem, we will need to divide two values and convert a decimal to a percentage.

First, set up the fraction of economics majors that are freshman students to the total number of freshman students.

[tex]\displaystyle \frac{1634}{8600}[/tex]

Then, divide the two using a calculator or long division.

[tex]\displaystyle \frac{19}{100}[/tex]

Finally, to convert this to a decimal, use a calculator.

[tex]0.19[/tex]

To convert a decimal to a percentage, multiply the decimal by 100.

[tex]0.19 \times 100 = 19\%[/tex]

The final answer is [tex]19\%[/tex].

19%

Key Points:

In order to find the percentage of freshman majoring in economics, we must divide the econ major students by the overall size of the freshman class.

[tex]\frac{1634}{8600}[/tex]

Our next step is to grab a calculator and input 1634 ÷ 8600. You can alternatively use the long division method but a calculator would work best. After calculating, your answer should come out to be 0.19

Now, you need to multiply it by 100 so that you can create a percentage.

0.19 × 100 = 19%

Therefore, 19% of the freshman class are economics majors.

a. The slope of a line that is parallel to y = 3/5x + 7 is: 3/5.

b. The slope of a line that is perpendicular to y = 3/5x + 7 is: -5/3.

Given a line is represented by the equation, y = 3/5x + 7, the slope (m) of the line is 3/5.

Any line that is parallel to y = 3/5x + 7 will have a slope (m) = 3/5 [same slope value].

On the other hand, any line that is perpendicular to y = 3/5x + 7 will have a slope of -5/3 [negative reciprocal].

Therefore:

a. The slope of a line that is parallel to y = 3/5x + 7 would be: 3/5.

b. The slope of a line that is perpendicular to y = 3/5x + 7 would be the negative reciprocal of 3/5, which is: -5/3.

yes, if the value of the coin is 1 dollar, then it will exceed the million dollars within 28 days.

It will depend on the original value of the coin, value that we don't know, so I will assume that the value of the coin is $1.

If this coin doubles each day, then the day zero its value is $1.

After one day its value is 2*$1 = $2

After another day its value is 2*$2 = $4

And so on, this is modeled by the exponential equation:

y = $1*(2)^x

Where y is the total value and x is the number of days.

After 28 days (this means we use x = 28) the value will be:

y = $1*(2)^28 = $268,435,456

Answer:

x=1 y=3

Step-by-step explanation:

Hello!

So, this says to use the substitution method. The substitution method is where you set one equation equal to one of the letters, and then put that whole equation in the other equation.

So->

3x-y=0

if we move the y to the other side we have:

3x=y

then we have our second equation:

2x+y=5

Now, we don't know what NUMBER y is yet, but we do know that it is equal to 3x. Thus, we can put it into the equation like this.

2x+(3x)=5

Then, we can add like terms and get:

5x=5

Dividing each term by five, we get

x=1

We could have also done this be solving for x in the equations and then substituting that in instead of y.

Now that we have x, we can easily put it into the equations and solve for y.

3x-y=0

3(1)-y=0

3=y

So now we know that x is equal to 1 and y is equal to 3.

Answer: (Looking back, I may have gotten this question wrong, but if I haven't then nice.)

a) 13 degrees

b) acute angle

Step-by-step explanation:

Given that we know a triangle is 180 degrees. Lets recall what an obtuse, acute, right and reflex angle are.

Obtuse: An angle greater than 90 degrees

Acute: An angle less than 90 degrees

Right: An angle that is 90 degrees

Reflex: An angle in between 180-360 degrees

Since we know that two of the three angles are 54 and 113 degrees, we can say that 54+113+x=180. That means that the missing angle, x, is 13 degrees.

Knowing that 13 is less than 90, we can also say that the third angle is an acute angle.

Step-by-step explanation:

Given the ordered pairs (t, P(t)) = (2, 3590) and (9, 4500), you want a linear model that describes the relation. You also want the value of P(16).

We can write the formula for P(t) starting with the point-slope equation for P in terms of t. To do that, we need the slope:

  m = (P2 -P1)/(t2 -t1)

  m = (4500 -3590)/(9 -2) = 910/7 = 130

The point-slope equation will be ...

  P -P1 = m(t -t1)

  P -3590 = 130(t -2)

Solving for P, we find ...

  P = 130t -260 +3590 . . . . . eliminate parentheses, add 3590

  P(t) = 130t +3330

The value of P(16) will be ...

  P(16) = 130(16) +3330 = 2080 +3330 = 5410

The moose population is predicted to be 5410 in 2006.

Given the ordered pairs (t, P(t)) = (2, 3590) and (9, 4500), you want a linear model that describes the relation. You also want the value of P(16).

A.) Linear model

We can write the formula for P(t) starting with the point-slope equation for P in terms of t. To do that, we need the slope:

Solving for P, we find

 P = 130t -260 +3590 . . . . . eliminate parentheses, add 3590

 P(t) = 130t +3330

B.) Prediction

The value of P(16) will be

 P(16) = 130(16) +3330 = 2080 +3330 = 5410

The moose population is predicted to be 5410 in 2006.
