<h3><u>
Answer:</u></h3>
Option: C is the correct answer.
$ 1.50 is the cost of 1 eraser.
<h3><u>
Step-by-step explanation:</u></h3>
Alicia bought a notebook and several erasers at the student store.
Let the cost of 1 eraser=$ x.
Now from the scatter plot we could see that when Alicia did not bought any eraser then her total cost =$ 2.
That means cost of a notebook=$ 2.
Now when she buys a notebook and two eraser then she pays=$ 5.
i.e.
Total cost=cost of notebook+ 2× cost of 1 eraser
Total cost=cost of notebook+2×x
i.e.
5=2+2x
⇒ 2x=5-2
⇒ 2x=3
⇒ x=1.5
Hence, cost of one eraser is:
$ 1.50
The calculated distance would be in square units instead of linear units.
Answer: Option C.
<u>Explanation:</u>
The Distance Formula itself is actually derived from the Pythagorean Theorem. This is the formula where c is the longest side of a right triangle (also known as the hypotenuse) and a and b are the other shorter sides (known as the legs of a right triangle).
The distance formula is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse. The hypotenuse of the triangle is the distance between the two points.
Answer:
r= -sec(θ) x ∛2
θ=0
Step-by-step explanation:
The initial deceleration is 4 m/s^2, so this means that considering the first line segment, 
.
The total distance traveled is 4 km, which is equal to 4000 meters. This is equal to the area under the graph, so 
.
