Answer:
EF = ≈ 5.83
Step-by-step explanation:
Calculate EF using the distance formula
d =
with (x₁, y₁ ) = E(1, 3) and (x₂, y₂ ) = F(- 2, 8)
EF =
=
=
= ≈ 5.83 ( to 2 dec. places )

Answer: The distance is 15
Step-by-step explanation:
To find the distance between L and Y find the difference in the x and y coordinates then square them and add them to find their square root.
-7-5= -12
0-9 = -9
12^2 + 9^2 = d^2 where d is the distance
144 + 81 = d^2
225 = d^2
d=
d= 15
Answer:
Silver
Step-by-step explanation:
Find the volume of the coin
<u>Volume of a cylinder</u>
Given:
- r = 1.5 cm
- h = 0.25 cm
Substituting given values into the formula to find the volume:
Find the density of the coin given it has a measured mass of 18.54 g
<u>Density formula</u>
where:
= density
- m = mass
- V = volume
Given:
- m = 18.54 g
Substituting given values into the density formula:
Given:
Therefore, as the coin is made from silver.
