djyliett [7]

Complete Question:

ABCD Is a rectangle that represents a park.

The lines show all the paths in the park.

The circular path is in the centre of the rectangle and has a diameter of 15m.

Calculate the shortest distance from A to C across the park,using only the lines shown.

*See attachment for the diagram showing the paths in the park.

Answer:

Shortest distance from A to C through the paths only = 102.9 m

Step-by-step explanation:

Length of park = 80 m

Width of park = 50 m

Diameter of the circular path in the center of the park = 15 m

Therefore:

Shortest distance between from A to C across the park if we're to follow only the lines showing the oaths would be = (length of diagonal AC - diameter of the circular path) + (½ of the circumference of the circular path)

✔️Use pythagorean theorem to find AC:

AC = √(80² + 50²) =  √8,900

AC = 94.3398113 ≈ 94.34 m (nearest hundredth)

✔️Diameter of circular path = 15 m

✔️½ of the circumference of the circular path = ½(πd)

d = 15 m

½ of the circumference = ½(π*15) = 23.5619449 ≈ 23.56 m (nearest hundredth)

✔️Shortest distance = (94.34 - 15) + 23.56 = 79.34 + 23.56 = 102.9 m

il63 [147K]

Change in speed  = (end speed) - (start speed)

                             =    (22 m/s)    -   (4 m/s)   =   18 m/s .


Magnitude of average acceleration =

                         (change in speed) / (time for the change) .

                     =                (18 m/s)  /  (3 sec)  =  6 m/s² .


That's about 0.61 G.

What is the rate of change and initial value for the linear relation that includes the
Aleonysh [2.5K]

Answer:

The initial value of the function is 25 and the rate of change is - 5.

Step-by-step explanation:

The table gives the ordered pairs of linear relation and they are (1,20) and (3,10).

Now, the equation of the linear relation that includes those ordered pairs will be  

\frac{y - 10}{10 - 20} = \frac{x - 3}{3 - 1}

⇒ y - 10 = - 5(x - 3)

⇒ y - 10 = - 5x + 15

⇒ y = - 5x + 25

Therefore, the initial value of the function is 25 and the rate of change is - 5. (Answer)

Find the value(s) of x such that f''(x)=0
Goryan [66]
f(x)=\dfrac x{x^2+2}\implies f'(x)=\dfrac{2-x^2}{(x^2+2)^2}\implies f''(x)=\dfrac{2x^3-12x}{(x^2+2)^3}

The denominator is always positive, so any x for which f''(x)=0 is determined only by the numerator:

2x^3-12x=0\implies f''(x)=0
2x^3-12x=2x(x^2-6)=2x(x-\sqrt6)(x+\sqrt6)=0\implies x=0,\pm\sqrt6
