Answer:
x = -8 or x + 8 = 0
Step-by-step explanation:
As the slope is undefined, the line is parallel to y-axis
The equation of the line : x = -8
Answer:
x³ + 2x² -3x +6
Step-by-step explanation:
We need to find the polynomial whose roots are ,
Say of we have zeroes as , α , β and γ , then the polynomial is ,
=> p(x) = k[ (x - α ) ( x - β) ( x - γ) ]
- where k is constant. Substituting the respective values , we have ,
=> p(x) = k [ ( x - (-2)) ( x - √3) ( x -√3)]
=> p(x) = k[ (x+2)(x² - 3)]
=> p(x) = k[ x(x² - 3) + 2(x² - 3) ]
=> p(x) = k[ x³ - 3x + 2x² - 6 ]
=> p(x) = k[ x³ + 2x² - 3x - 6 ]

Answer:
c
Step-by-step explanation:
with a fractional exponent, the denominator becomes the root number. so we need a root of 3, which only b and c have.
between those two, b has no negative present whereas c does. since the original exponent was -5/3 we know our answer should have one.
thus c is our answer.
Make them have common denominators: -2/8 - 3/8 - 6/8 - 7/8 =
Now just do subtraction with numerators: -5/8 - 6/8 -7/8 = -11/8 - 7/8 = -18/8 =
Simplify: -9/4 =
Make it a mixed fraction: -2 1/4 (D)
Answer:
The formula to find the volume of a cylinder is V = πr2h
The diameter divided by 2 is the radius. 5.5 divided by 2 is 2.75
v = π2.752 16.5
V = 391.8
The answer is 391.8
