Answer:
The slope is 3
Step-by-step explanation:
Rise / Run
3 / 1
= 3
For this case we have that by definition, a linear function is of the form
We have the following options:
A)
Rewriting:
It's a quadratic function!
B)
Rewriting:
It's a linear function!
C)
Rewriting:
It's a cubic function.
D)
Rewriting:
It's a quadratic function!
E)
Rewriting:
It's a cubic function!
Answer:
The linear function is option B

Answer:
- slant height: 2.1 cm
- pencil area: 51.12 cm^2
Step-by-step explanation:
The slant height (s) is the hypotenuse of the right triangle with legs of 2 cm and 0.5 cm.
s^2 = 2^2 + 0.5^2 = 4 + 0.25
s = √4.25 ≈ 2.0616 ≈ 2.1
The slant height is about 2.1 cm.
__
The surface area of the whole pencil is the sum of the areas of the circular base, the lateral area of the cylindrical part, and the lateral area of the cone.
A = πr^2 +2πrh +πrs
A = πr(r +2h +s) = (3.14)(0.5 cm)(0.5 cm + 2×15 cm + 2.1 cm)
A ≈ 51.12 cm^2
The area of the whole pencil is about 51.12 cm^2.
You just gotta do 3.14 • 8^2
