Answer:
x =34.56°
Step-by-step explanation:
adjacent/ hypotenuse =cosx
cosx = 14/17
x = 
(14/17)
x =34.56°
A line parallel to y=2x+4 that contains the point (3,-2) is y=2x-8. The line is parallel because it has the same slope as AB, and we can find the intercept by plugging in (3,-2) into slope-intercept form and solving for b.
Answer:
The volume of the cone is 128π mm³ ⇒ answer (C)
Step-by-step explanation:
* Lets study the cone
- Its base is a circle
- Its height the perpendicular distance from its vertex to
the center of the base
- The length of its slant height = √(h² + r²)
- The volume of the con is 1/3 the volume of the cylinder
∵ The volume of the cylinder = πr²h
∴ The volume of the cone = (1/3) πr²h
* In our problem:
- r = 4 mm
- h = 24 mm
∴ Its volume = (1/3) × π × (4)² × 24 = 128π mm³
* The volume of the cone is 128π mm³
