Answer:

Your answer is D

Step-by-step explanation:

f(2) This means that x is 2, so you can plug in 2 for "x" in the equation

f(x) = 3x - 12

f(2) = 3(2) - 12

f(2) = 6 - 12

f(2) = -6

Answer:

10 people

Step-by-step explanation:

Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.

The amount spent on just tickets is therefore:

= 243.25 - 15.75

= $227.50.

If $227.50 was for tickets alone, the number of tickets they could buy is:

= Total amount left/ Price of tickets

= 227.50 / 22.75

= 10 people

Twice a number decreased by 11 is -23
strojnjashka [21]

Twice a number decreased by 11 is -23

Let the number be x

So we get the equation

2x -11 = -23

Add 11 to both sides

2x = -12

Divide both sides by 2

x = -6

So the number is -6

Negative 6

The graph shows the distance y, in centimeters, a pendulum moves to the right (positive displacement) and to the left (negative
AVprozaik [17]

Time required for the pendulum to swing from its position furthest to the right to its position furthest to the left: 1.25 seconds

Step-by-step explanation:

A pendulum is a system consisting of a rod/string connected to a mass which is left free to oscillate back and forth around its equilibrium position, straight vertical.

The period of a pendulum is the time the pendulum takes to complete one full oscillation, that means it is the time the pendulum takes to go from its furthest position on the left to the same position again. It is calculated as

T=2\pi \sqrt{\frac{L}{g}}

where L is the length of the pendulum and g the acceleration of gravity.

The figure in this problem represents the position of the pendulum. We observe that the time it takes for the pendulum to do one complete oscillation is 2.5 seconds.

The time it takes for the pendulum to swing from its position furthest to the right to its position furthest to the left is half the period: therefore, it is

\frac{T}{2}=\frac{2.5}{2}=1.25 s
