Answer:
2nd option
Step-by-step explanation:
Substitute the values of x from the domain into f(x) for range
f(2) = 2³ + 1 = 8 + 1 = 9
f(3) = 3³ + 1 = 27 + 1 = 28
f(4) = 4³ + 1 = 64 + 1 = 65
range is {9, 28, 65 }
Brian as 8 cards.
The fraction that show how many are baseball cards is 5/8, because 5 cards from the total amount are baseball cards. Good luck !

Answer:
![c=0.4\ J/g^{\circ} C](https://tex.z-dn.net/?f=c%3D0.4%5C%20J%2Fg%5E%7B%5Ccirc%7D%20C)
Step-by-step explanation:
Given that,
Mass of a sample, m = 12 g
Heat absobed by the sample, Q = 96 J
It was heated from 20°C to 40°C.
We need to find the specific heat of a material. The heat absorbed by a sample is given by :
![Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{96}{12\times (40-20)}\\\\=0.4\ J/g^{\circ} C](https://tex.z-dn.net/?f=Q%3Dmc%5CDelta%20T%5C%5C%5C%5Cc%3D%5Cdfrac%7BQ%7D%7Bm%5CDelta%20T%7D%5C%5C%5C%5Cc%3D%5Cdfrac%7B96%7D%7B12%5Ctimes%20%2840-20%29%7D%5C%5C%5C%5C%3D0.4%5C%20J%2Fg%5E%7B%5Ccirc%7D%20C)
So, the specific heat of the material is
.
The amount of metal used to make the can = surface area of cylindrical can, which is: D. 42π in².
<h3>What is the Surface Area of a Cylinder?</h3>
A can is a cylinder.
Surface area of a cylinder = 2πrh + 2πr²
Thus:
Amount of metal used to make the can = surface area of the can
r = 6/2 = 3 in.
h = 4 in.
Therefore:
Surface area = 2×π×3×4 + 2×π×3²
Surface area = 24π + 18π
Surface area = 42π in².
