Answer is
B.) As x approaches negative infinity, f(x) approaches positive infinity.
The mass of the rock is 3020.27 grams , if a rock is in the shape of a sphere with a radius of 5.08 centimeters and the rock has a density of 5.5 grams per cubic centimeter,
Step-by-step explanation:
The given is,
Radius of the rock is 5.08 cm (Sphere)
Density of rock 5.5 grams per cubic centimeters
Step:1
Formula for volume of sphere,
..........................(1)
Where, r - Radius of sphere
From the given values,
r = 5.08 cm
Equation (1) becomes,



V = 549.14 cubic centimeters
Step:2
Mass of rock = Volume of rock × Density of rock
= 549.14 × 5.5 ( ∵
)
= 3020.27 grams
Mass of the rock = 3020.27 grams
Result:
The mass of the rock is 3020.27 grams , if a rock is in the shape of a sphere with a radius of 5.08 centimeters and the rock has a density of 5.5 grams per cubic centimeter,
Answer:
3n+5
Step-by-step explanation:
Like terms are the terms that can be added together, in this example, 7 and -2. There aren't any other like terms so if you add them together, the answer would be 3n+5.

Answer:

Step-by-step explanation:






The volume and surface area of the pyramid will be 392 / 3 cubic units and 189 square units. Then the correct option is A.
The complete question is attached below.
<h3>What is the volume and surface area of the pyramid? </h3>
Suppose the base of the pyramid has length = L units, width = W units, slant height = K units, and the height of the pyramid is of H units.
Then the volume of the pyramid will be
V = (L × B × H) / 3
The surface area of the pyramid will be
SA = 2(1/2 × B × K) + 2(1/2 × L × K) + (L × B)
Then the volume will be
V = (7 × 7 × 8) / 3
V = 392/3 cubic units
Then the surface area will be
SA = 2(1/2 × 7 × 10) + 2(1/2 × 7 × 10) + (7 × 7)
SA = 189 square units
Then the correct option is A.
