Step-by-step explanation:
Given expression is x⁴-kx²+4 =0
x−2 is a factor of the given expression.
So, x=2
Substitute in the equation, we get
2⁴-k(2)²+4
⇒16+4k+4=0
⇒4k=−20
⇒k=−5
Answer:
sometimes
Step-by-step explanation:
Answer:
A: The height of the cylinder is 3.4 ft.
C: The diameter of the cylinder is about 3 ft.
E: A right cylinder with the same height and radius as this oblique cylinder would also have a volume of 24 ft3.
Step-by-step explanation:
4:12 equals 2:6 equals 1:3.
The ratio is 1 banana to 3 oranges.
(0,5)(3,-1)
slope = (-1 - 5) / (3 - 0) = -6/3 = -2
y = mx + b
slope(m) = -2
(use either of ur points...(0,5)...x = 0 and y = 5
now we sub and find b, the y int
5 = -2(0) + b
5 = b
so ur line is : y = -2x + 5
