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.

Answer:

C

Step-by-step explanation:

it is trust me

−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:

45km

Step-by-step explanation:

Given data

Average Speed= 15km/h

Time = 3 hours

Required

The distance traveled

Speed= distance/time

Distance= speed*time

Distance= 15*3

Distance= 45km

Hence the lower bound of the distance is 45km

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:

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:

Sack A will require more water because it is larger.

Answer:

-3 i think

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:

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:

[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]
