When you look at the graph, the X is the x value and the one on the f(x) is the y value, imagian it is on a graph and x is the steps you have to walk then imagain a ladder you have to go as high as the f(x) value says, then mark them. if they follow a pattern then write it down, if it does not then write incosentant.

Have a nice day.

A trapezoid has base lengths of 12 centimeters and 13 centimeters. The other sides have lengths of 5 centimeters and 10 centimet
r-ruslan [8.4K]

Answer:

The area of the composite figure is 392.12cm^{2}.

Step-by-step explanation:

The area of the composite figure = area of trapezoid + area of rectangle

Area of trapezium = \frac{1}{2} ( a +b)h

Where: a is the length of the first base, b the length of the second base and h is the height of the trapzium.

Applying Pythagoras theorem, the height, h, is;

h = \sqrt{5^{2} - 1^{2}  }

  = \sqrt{24}

h  = 2\sqrt{6}

Area of trapezium = \frac{1}{2} ( a +b)h

                              = \frac{1}{2} (13 + 12) × 2\sqrt{6}

                              = 156\sqrt{6}

                              = 382.12cm^{2}

Area of trapezium is 382.12cm^{2}

Area of rectangle = length × width

                             = 5 × 2

                             = 10 cm^{2}

Area of rectangle = 10 cm^{2}

Therefore,

area of the composite figure = 382.12 + 10

                                               = 392.12cm^{2}

Determine the mechanical energy of this object a 1kg pendulum at a height of 1-meter
Lemur [1.5K]

Answer:

A

Step-by-step explanation:

Mechanical energy (ME) is Kinetic energy + potential energy

Where

Kinetic Energy (KE) = 1/2 * m * v^2

where m is the mass (in kg) and v is the speed of the object (in m/s)

and

Potential Energy (PE) = m*g*h

Where m is the mass (in kg) and g is the gravitational constant (9.81 m/s) and h is the height (in meters)

Hence

ME = KE + PE (note the pendulum DOES NOT have any speed, so v = 0, and thus KE = 0)

So,

ME=KE+PE\\ME=\frac{1}{2}mv^2+mgh\\ME=\frac{1}{2}(1)(0)^{2}+(1)(9.81)(1)\\ME=0+9.81\\ME=9.81

Hence, Mechanical Energy is 9.8 Joules (rounded to 1 decimal place). Correct answer is A.

Is the following situation proportional? Justify your answer. At an arcade, Aisha pays $2 for each game she plays.
Over [174]

Yes, the situation as described is proportional.

Discussion:

According to the question:

  • We are required to determine if the situation described in the question is proportional.

Since, Aisha pays $2 for each game she plays at the arcade.

In essence, the total amount of money paid by Aisha will depend on the number of games she plays. On this note, the situation is proportional.
