What is the y intercept of f(x)=(1/2)*
9966 [12]

Answer:

B. (0,0)

Step-by-step explanation:

The y-intercept of the equation f(x) = 1/2x lies on the y-axis.

This means we need to set x = 0 and solve for y

1/2(0) = 0

Therefore, (0,0) is the y-intercept of this equation.

Consider it this cone with a diameter of 19 cm use the drop-down menus to describe the con measurements
MAVERICK [17]

Answer:

1) Radius of the cone = 9.5 cm

2) BA = 90.25 π cm²

3) SA = 384.7 π cm²

Step-by-step explanation:

1) Radius of the cone = 9.5 cm

2) Base Area of the cone = \pi r^2

BA = (π)(9.5)²

BA = 90.25 π cm²

3) Surface Area of Cone = \pi r(r+\sqrt{h^2+r^2)}

SA = π(9.5)(9.5 + √(29.5)²+(9.5)²)

SA = 9.5π(9.5 + 31)

SA = 9.5π(40.5)

SA = 384.7 π cm²
