Answer:
x = 3, x = -
Step-by-step explanation:
Since x = 2 is a root then (x - 2) is a factor
2x³ - 3x² - 23x + 42 ÷ (x - 2)
= (x - 2)(2x² + x - 21)
solve 2x² + x - 21 = 0 for remaining roots
(2x + 7)(x - 3) = 0
equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
2x + 7 = 0 ⇒ x = -
Answer:
The volume of the sphere with radius 8 cm is 2143.573 centimeters³
Step-by-step explanation:
Given as :
The radius of the sphere = r = 8 cm
Let The volume of sphere = v cm³
<u>Now, According to question</u>
Volume of sphere = × π × radius³
where r is radius of sphere
π = 3.14
Or, v = × 3.14 × r³
Or, v = × 3.14 × 8³
Or, v = × 1607.68
Or, v =
∴ v = 2143.573 cm³
So, The volume of the sphere = v = 2143.573 cm³
Hence, The volume of the sphere with radius 8 cm is 2143.573 centimeters³ Answer
