In displacement-time graph, Scale factors:
20 Feet & 0.5 second for each instant

1) Velocity = Final position - Initial position / Final time - Initial time
v = 100 - 60 / 1 - 0
v = 40 / 1
v = 40

In short, Your Answer would be 40 ft/sec

2) Velocity = 0 - 60 / 4 - 0
v = -60 / 4
v = -15

In short, Your Answer would be -15 ft/sec
[ Negative sign indicates that it is decreasing due to opposite direction ]

Dominick weighs 30 pounds more than his sister. Together they weigh 330 pounds. How much does Dominick weigh?
german

Domik weights 30 pounds more than his sister

Together they weigh 330 pounds

Let "x" represent the weight of Dominik's sister, then his weight can be expressed as "x+30"

And their total weight can be calculated as:

x+(x+30)=330

From this expression you can calculate the value of x:

\begin{gathered} 2x+30=330 \\ 2x+30-30=330-30 \\ 2x=300 \\ \frac{2x}{2}=\frac{300}{2} \\ x=150 \end{gathered}

x=150 pounds

x+30=150+30=180 pounds

Dominik weights 180pounds and his sister 150 pounds

According to the equation, which choice represents the fixed cost of
kodGreya [7K]

Answer:

A) 3500

Step-by-step explanation:

C(x) = 0.75x + 3500

C(x) = Total cost

0.75x = variable cost

3,500 = fixed cost

The fixed cost of the function = 3,500

Variable cost refers to cost of production that changes during production such as cost of raw material, wages of workers etc.

Fixed cost are cost of production that remains the same (does not change) with the production process such as building, machineries etc

Total cost is the addition of all cost of production, that is, the addition of fixed cost and variable cost
