Answer: C.  A Ball Rolls from top to the bottom of a Hill

Step-by-step explanation: In order for this to be a displacement of 0, we need a vector quantity, so we need to specify a magnitude and direction in order to fully characterize it. Unlike distance, which can only get larger on any path taken, displacement can be positive, negative, or zero. Displacement is zero when you start and end at the same spot.

[tex]\displaystyle \tan A=\frac{4}{3}[/tex]

Step-by-step explanation:

Funciones Trigonométricas

La identidad principal en trigonometría es:

[tex]sen^2A+cos^2A=1[/tex]

Si sabemos que A es un ángulo agudo (que mide menos de 90°), su seno y coseno son positivos.

Dado que Sen A = 4/5, calculamos el coseno:

[tex]cos^2A=1-sen^2A[/tex]

Sustituyendo:

[tex]\displaystyle cos^2A=1-\left(\frac{4}{5}\right)^2[/tex]

[tex]\displaystyle cos^2A=1-\frac{16}{25}[/tex]

[tex]\displaystyle cos^2A=\frac{25-16}{25}[/tex]

[tex]\displaystyle cos^2A=\frac{9}{25}[/tex]

Tomando raíz cuadrada:

[tex]\displaystyle cos\ A=\sqrt{\frac{9}{25}}=\frac{3}{5}[/tex]

La tangente se define como:

[tex]\displaystyle \tan A=\frac{sen\ A}{cos\ A}[/tex]

Substituyendo:

[tex]\displaystyle \tan A=\frac{\frac{4}{5}}{\frac{3}{5}}[/tex]

[tex]\displaystyle \tan A=\frac{4}{3}[/tex]

Answer:

7/10

Step-by-step explanation:

Answer: [tex]-\frac{7}{10}[/tex]

Step-by-step explanation:

Ordered pairs are written as (x,y)

The difference between the x coordinates is -10

The difference between the y coordinates is -7

Slope is written as [tex]\frac{rise}{run}[/tex]

So, the slope is [tex]-\frac{7}{10}[/tex]

Answer:

48,400 yd²

Step-by-step explanation:

(220+180)/2*260=52000

1/2(180)(60)=5400

So the total area is 52000+5400=57400

Basketball court=2400

Picnic area = 4200

Playground = 40x50 + 10x40=2400

2400+4200+2400=9000

57400-9000=48400

Answer:

[tex]y = 7x - 3.5[/tex]

Answer:

25520 yds

Step-by-step explanation:

Answer:

25,520

Step-by-step explanation:

The formula for yards to miles is that you have multiply the length value by 1760.

So 14.5 * 1,760 = 25,520

Step-by-step explanation:

For no 1

25 - 3x = 40

- 3x = 40 - 25

- 3x = 15

- x = 15 / 3

Therefore x = - 5

Now for no. 2

1/3 ( x - 10) = - 4

( x - 10 ) = - 12

x = - 12 + 10

Therefore x = - 2

Hope it will help :)

Answer:

4x+2y

Step-by-step explanation:

Answer:

Step-by-step explanation:

1).b).  2x - 3y > 5

   For (2, 1),

   2(2) - 3(1) > 5

    1 > 5

    False.

   So the answer is NO.

c). For (6, 2),

    2(6) - 3(2) > 5

    12 - 6 > 5

    6 > 5

    True.

    Therefore, the answer is YES.

2). a). 3y + x ≤ 12

    For (3, -2),

    3(-2) + 3 ≤ 12

    -6 + 3 ≤ 12

     -3 ≤ 12

     True.

     Therefore, answer is YES.

b). For (4, 6),

    3(6) + 4 ≤ 12

     18 + 4 ≤ 12

     22 ≤ 12

     False.

     Therefore, answer is NO.

c). For (-1, -2),

    3(-2) + (-1) ≤ 12

     -6 - 1 ≤ 12

     -7 ≤ 12

     True.

     Therefore, answer is YES.

3). a). y < 3x - 15

      For (5, -3),

      -3 < 3(5) - 15

      -3 < 0

       True.

      Therefore, answer is YES.

 b). For (7, 5),

      5 < 3(7) - 5

      5 < 21 - 5

      5 < 16

      True.

      Therefore, answer is YES.

  c). For (3, -5),

       -5 < 3(3) - 5

       -5 < 9 - 5

       -5 < 4

        True.

       Therefore, answer is YES.

Step-by-step explanation:

So I didnt really understand the beginning but what I did was $325x24=$7800 payed in 24 months if we are adding the $4500 it would be

$7800+$4500=$12300

Step-by-step explanation:

So I didnt really understand the beginning but what I did was $325x24=$7800 payed in 24 months if we are adding the $4500 it would be

$7800+$4500=$12300

−10x+5y=10

x−5y=−28

Rewrite equations:

x−5y=−28

−10x+5y=10

Step: Solve:

x−5y=−28

x−5y+5y=−28+5y(Add 5y to both sides)

x=5y−28

Step: Substitute:

−10x+5y=10

−10(5y−28)+5y=10

−45y+280=10(Simplify both sides of the equation)

−45y+280+−280=10+−280(Add -280 to both sides)

−45y=−270

−45y

−45

=

−270

−45

(Divide both sides by -45)

y=6

Step: Substitute:

x=5y−28

x=(5)(6)−28

x=2(Simplify both sides of the equation)

Answer:

x=2 and y=6

Answer:

slope = ⅔

y intercept = -2

so
