The value of x is 25 degrees if XY is parallel to the BC option (b) 25 degrees is correct.

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

A circle is given:

XY ║ BC

x = angle XYB

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

Angle BAX = Angle XYB

In triangle AXY, Angle XAY = 90 degrees

Angle BAX = 90 - Angle BAY

x = Angle BAX = 90 - 65

x = 25 degrees

Thus, the value of x is 25 degrees if XY is parallel to the BC option (b) 25 degrees is correct.

The graph below describes the journey of a train between two cities.
Veseljchak [2.6K]

Answer:

[A] Acceleration in first 15 min = 200  km/h²

[B] Distance between two cities = 125 km

[C] Average Speed of journey =  62.5  km/hr

Step-by-step explanation:

To Solve:

Acceleration in first 15 min

Distance between two cities  

Average speed of journey

Solve:

[A] Work out the acceleration, in km/h?, in the first 15 mins.

Each horizontal block is 1/8 hr = 7.5 min

Each vertical block is 10 km/hr

Time                     Velocity  km/hr

0 Min  ( 0 hr)            0

15 Min (1/4 hr)           50

45 Min (3/4 hr)         50

60 MIn  ( 1 hr)            100

90 Min  ( 3/2 hr)        100

120 Min ( 2hr)            0

Acceleration in first 15 min  (1/4 hr)  =  (50 - 0)/(1/4 - 0)  = 50/(1/4)

= 200  km/h²

Hence, Answer for [A] = 200  km/h²

[B] Work out the distance between the two cities. $60 Velocity (in km/h)

= (1/2)(0 + 50)(1/4 - 0)  + 50 * (3/4 - 1/4)  + (1/2)(50 + 100)(1 - 3/4)  + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)

=  25/4  + 25 + 75/4   + 50 + 25

= 125

Distance between two cities = 125 km

[C] Work out the average speed of the train during 20 the journey.

Average Speed of journey = 125/2  = 62.5  km/hr

The function, f(x)=70n-400, models the profit the instructor of guitar class per month, where n is the number of students enroll
densk [106]
The instructor wants the profit to be positive, so
  f(n) > 0
  70n -400 > 0
  n - 400/70 > 0
  n > 5 5/7

The instructor must enroll at least 6 students to make a profit.
