A cone is formed from a 300-degree sector of a circle of radius 18 by aligning the two straight sides. what is the result when t

vampirchik [111]

The radius of the completed cone is

... 18×(300°/360°) = 15

The height of the completed cone is found from the Pythagorean theorem:

... 15² + h² = 18²

... h = √99 = 3√11

The volume is given by

... V = (1/3)πr²·h = (1/3)π·15²·3√11

Dividing this value by π gives 225√11 cubic units.

Answer:

(a) y = -4x + 4 (b) y = 2x + 3

solving steps:

note: m refers to slope and y₁ to y point and x₁ to x point

coordinates: (2,-4)

slope: -4

equation:

y - y₁ = m(x - x₁)

y - -4 = -4(x-2)

y = -4x + 8 - 4

y = - 4x + 4

coordinates: (1,5), (-1,1)

slope: $\sf \dfrac{y-y_1}{x-x_1}$

$\sf \dfrac{1-5}{-1-1}$

equation:

y - y₁ = m(x - x₁)

y - 5 = 2(x - 1)

y - 5 = 2x - 2

y = 2x - 2 + 5

y = 2x + 3

Solve the radical equation. Be sure to check all solutions to eliminate extraneous solutions.

tatyana61 [14]

Answer: $\large\boxed{\text{No Solution}}$

Step-by-step explanation:

Given equation

$\sqrt{t+1}+9=7$

Subtract 9 on both sides

$\sqrt{t+1}+9-9=7-9$

$\sqrt{t+1}=-2$

Conclusion

$\text{Since radical values are always positive, it is false that }\sqrt{t+1}\text{ will equal to -2}$

$\text{Therefore, it is }{\large\boxed{\text{No Solution}}}\text{ in the context of real numbers}$

Hope this helps!! :)
