Answer:

y=5441t+123,000

Step-by-step explanation:

5441 is the population increase per year and 123,000 is when we start added the population increase. to get this equation i found the population increase between 2007 and 1990 which is 215,500-123,000 which is 92,500. to find the population increase per year you divide that by 17 which is the difference between 2007 and 1990 and you would get 5441.176. but since you can have part of a person i rounded it to 5441.

Answer: y=5441t+123000

We know the population was 215500 in 2007

We also know the population was about 123000 in 1990

So first we want to find the slope (m=y2-y1/x2-x1), we subtract those two numbers 215500-123000 and subtract 2007-19990. Leaving us with 92500/17, once you divide that you’ll get 5441.17647 . But since we are talking about people you round to the nearest whole number leaving us with 5441.

(-1, -2), (-2, -1) and (2, -4) are solutions to the inequality

The given inequality is:

-x - 2y  >  3

To know which of the points given as options are the solutions to the given inequality, substitute the given points into -x - 2y, anyone that gives a result greater than 3 is a solution to the inequality

For (-1, -2)

Substitute x = -1, and y = -2 into -x - 2y

-(-1) - 2(-2)

= 1 + 4

= 5

Since 5 > 3, (-1, -2) is a solution to the inequality

For (1, -2)

Substitute x = 1, and y = -2 into -x - 2y

-(1) - 2(-2)

= -1 + 4

= 3

Since the result is not greater than 3, (1, -2) is not a solution to the inequality

For (-2, -1)

Substitute x = -2, and y = -1 into -x - 2y

-(-2) - 2(-1)

= 2 + 2

= 4

Since  4 > 3, (-2, -1) is a solution to the inequality

For (2, -4)

Substitute x = 2, and y = -4 into -x - 2y

-(2) - 2(-4)

= -2 + 8

= 6

Since   6 > 3, (2, -4) is a solution to the inequality

Therefore, (-1, -2), (-2, -1), and (2, -4) are solutions to the inequality

Answer:

√65

Step-by-step explanation:

We know that √64 is 8

So, the square root of the number closest to 64 in the list will be the closest to 8

In the List, √62 = √(64-2)       [difference of 2]

√65 = √(64 + 1)                       [difference of 1]

Since √65 has the least difference from √64, we can say that √65 will be the closest to 8 in the given list

The value of the impulse will be 30 Newton-second. And the value of the momentum will be 30 kg-m/s.

A strong and ignorant passion or drive to act is known as an impulse.

A traveling body's momentum is measured as the combination of its mass and velocity.

A 6.00 N force acts for 5.00 seconds on a 1.50 kg mass.

Then the impulse is given as

Impulse = Force x Time

Impulse = 6 x 5

Impulse = 30 N-sec

Then the value of the momentum will be

P = m x dv

We know

F = ma

6 = 1.5a

a = 4 m/s²

Then the velocity will be

dv = a x t

dv = 4 x 5

dv = 20 m/s

Then the momentum will be

P = 1.5 x 20

P = 30 kg-m/s

1     f(1)   (1, f(1) )

and so on

Answer:

c

Step-by-step explanation:

Answer:

Written in Python

def sums(n):

    total = 0

    for i in range(1,n+1):

         if i%2 == 0:

              total = total + i*2

         else:

              total = total + i

    return(total)

Step-by-step explanation:

The function is written in Python

def sums(n):

This initializes total to 0

    total = 0

This iterates through the integers that makes up n i.e. 1,2,3.....n

    for i in range(1,n+1):

This checks if current digit is even

         if i%2 == 0:

If yes, it adds the double of the digit

              total = total + i*2

         else:

If otherwise, it adds the digit

              total = total + i

This prints the calculated sum or total

    return(total)

To call the function from main, use the following:

print(sums(n))

Answer:

1. [tex]y = 3x[/tex]

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

3. [tex]y = -\frac{2}{3}x - 4[/tex]

4. [tex]y = 4[/tex]

5. [tex]y = x + 5[/tex]

6. [tex]y= \frac{5}{2}x[/tex]

7. [tex]y = -7x -16[/tex]

8. [tex]y = x + 4[/tex]

Step-by-step explanation:

The steps to solving these questions involve

1. Calculate slope using: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

2. Calculate the line equation using point slope formula: [tex]y - y_1 = m(x - x_1)[/tex]

We'll apply the steps above in solving 1 through 8

Solving (1):

When x = 0; y = 0

When x = 1; y = 3

i.e.

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (1,3)[/tex]

Calculate slope:

[tex]m=\frac{3 - 0}{1 - 0}[/tex]

[tex]m=\frac{3 }{1 }[/tex]

[tex]m = 3[/tex]

Next, we calculate the equation

[tex]y - y_1 = m(x - x_1)[/tex]

Where:

[tex](x_1,y_1) = (0,0)[/tex] and [tex]m = 3[/tex]

[tex]y - 0 = 3(x - 0)[/tex]

[tex]y = 3x[/tex]

Solving (2):

When x = 0; y = 1

When x = 3; y = -1

i.e.

[tex](x_1,y_1) = (0,1)[/tex]

[tex](x_2,y_2) = (3,-1)[/tex]

Calculate slope:

[tex]m=\frac{-1 - 1}{3 - 0}[/tex]

[tex]m= -\frac{2}{3}[/tex]

Next, we calculate the equation

[tex]y - y_1 = m(x - x_1)[/tex]

Where:

[tex](x_1,y_1) = (0,1)[/tex] and [tex]m= -\frac{2}{3}[/tex]

[tex]y - 1 = -\frac{2}{3}(x - 0)[/tex]

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

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

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

Solving (3):

When x = 0; y = -4

When x = -3; y = -2

i.e.

[tex](x_1,y_1) = (0,-4)[/tex]

[tex](x_2,y_2) = (-3,-2)[/tex]

Calculate slope:

[tex]m=\frac{-2 - (-4)}{-3 - 0}[/tex]

[tex]m=\frac{-2 +4}{-3 - 0}[/tex]

[tex]m=\frac{2}{-3}[/tex]

[tex]m=-\frac{2}{3}[/tex]

Next, we calculate the equation

[tex]y - y_1 = m(x - x_1)[/tex]

Where:

[tex](x_1,y_1) = (0,-4)[/tex] and [tex]m= -\frac{2}{3}[/tex]

[tex]y - (-4) = -\frac{2}{3}(x - 0)[/tex]

[tex]y +4 = -\frac{2}{3}(x)[/tex]

[tex]y +4 = -\frac{2}{3}x[/tex]

[tex]y = -\frac{2}{3}x - 4[/tex]

Solving (4):

When x = 0; y = 4

When x = 4; y = 4

i.e.

[tex](x_1,y_1) = (0,4)[/tex]

[tex](x_2,y_2) = (4,4)[/tex]

Calculate slope:

[tex]m=\frac{4 - 4}{4 - 0}[/tex]

[tex]m=\frac{0}{4}[/tex]

[tex]m = 0[/tex]

Next, we calculate the equation

[tex]y - y_1 = m(x - x_1)[/tex]

Where:

[tex](x_1,y_1) = (0,4)[/tex] and [tex]m = 0[/tex]

[tex]y - 4 = 0(x - 0)[/tex]

[tex]y - 4 = 0[/tex]

[tex]y = 4[/tex]

Solving (5):

When x = -4; y = 1

When x = -1; y = 4

i.e.

[tex](x_1,y_1) = (-4,1)[/tex]

[tex](x_2,y_2) = (-1,4)[/tex]

Calculate slope:

[tex]m=\frac{4 - 1}{-1 - (-4)}[/tex]

[tex]m=\frac{4 - 1}{-1 +4)}[/tex]

[tex]m=\frac{3}{3)}[/tex]

[tex]m = 1[/tex]

Next, we calculate the equation

[tex]y - y_1 = m(x - x_1)[/tex]

Where:

[tex](x_1,y_1) = (-4,1)[/tex] and [tex]m = 1[/tex]

[tex]y - 1 = 1(x - (-4))[/tex]

[tex]y - 1 = 1(x +4)[/tex]

[tex]y - 1 = x +4[/tex]

[tex]y = x +4 + 1[/tex]

[tex]y = x + 5[/tex]

Solving (6):

When x = 0; y = 0

When x = 2; y = 5

i.e.

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (2,5)[/tex]

Calculate slope:

[tex]m=\frac{5 - 0}{2 - 0}[/tex]

[tex]m=\frac{5 }{2 }[/tex]

Next, we calculate the equation

[tex]y - y_1 = m(x - x_1)[/tex]

Where:

[tex](x_1,y_1) = (0,0)[/tex] and [tex]m=\frac{5 }{2 }[/tex]

[tex]y - 0 = \frac{5}{2}(x - 0)[/tex]

[tex]y - 0 = \frac{5}{2}(x)[/tex]

[tex]y= \frac{5}{2}x[/tex]

Solving (7):

When x = -2; y = -2

When x = 2; y = 5

i.e.

[tex](x_1,y_1) = (-2,-2)[/tex]

[tex](x_2,y_2) = (-3,-5)[/tex]

Calculate slope:

[tex]m=\frac{5 - (-2)}{-3 - (-2)}[/tex]

[tex]m=\frac{5 +2}{-3 +2}[/tex]

[tex]m=\frac{7}{-1}[/tex]

[tex]m =-7[/tex]

Next, we calculate the equation

[tex]y - y_1 = m(x - x_1)[/tex]

Where:

[tex](x_1,y_1) = (-2,-2)[/tex] and [tex]m =-7[/tex]

[tex]y - (-2) = -7(x - (-2))[/tex]

[tex]y +2 = -7(x +2)[/tex]

[tex]y +2 = -7x -14[/tex]

[tex]y = -7x -14 - 2[/tex]

[tex]y = -7x -16[/tex]

Solving (8):

When x = -3; y = 1

When x = 0; y = 4

i.e.

[tex](x_1,y_1) = (-3,1)[/tex]

[tex](x_2,y_2) = (0,4)[/tex]

Calculate slope:

[tex]m = \frac{4 - 1}{0 - (-3)}[/tex]

[tex]m = \frac{4 - 1}{0 +3}[/tex]

[tex]m = \frac{3}{3}[/tex]

[tex]m = 1[/tex]

Next, we calculate the equation

[tex]y - y_1 = m(x - x_1)[/tex]

Where:

[tex](x_1,y_1) = (-3,1)[/tex] and [tex]m = 1[/tex]

[tex]y - 1 = 1(x - (-3))[/tex]

[tex]y - 1 = 1(x +3)[/tex]

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

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

[tex]y = x + 4[/tex]
