Which of the following quartic functions has x=-1 and x=-2 as its only two real zeros

Mathematics

Brums [2.3K]3 years ago
4 0
Quartic is 4th degree
the factors of an equation with roots r1,r2 is
(x-r1)(x-r2)
4th degree
it could be
(x-r1)¹(x-r2)³ or
(x-r1)²(x-r2)² or
(x-r1)³(x-r2)¹


roots or zeroes at x=-1 and x=-2
(x-(-1)) and (x-(-2))
(x+1) and (x+2)

the function could be factored into
(x+1)¹(x+2)³ or
(x+1)²(x+2)² or
(x+1)³(x+2)¹

expanded would be
x⁴+7x³+18x²+20x+9 or
x⁴+6x³+13x²+12x+4 or
x⁴+5x³+9x²+7x+2
one of those is the answer

What is the equation in point-slope form of the line that passes through the point (-1, -4) And has a slope of -3?
Reptile [31]
Point-slope form is y- y_{1} =m(x- x_{1} ) where y1 and x1 are your points from the coordinate and m is the slope.  So yours would look like this: y-(-4)=-3(x-(-1)) or y + 4 = -3(x + 1)

Assume that BC is tangent to circle A. Find the value of x. Round your answer to the nearest tenth
Natalija [7]

Answer:

x ≈ 9.6

Step-by-step explanation:

Δ ABC is right with ∠ C = 90° ( angle between tangent and radius )

Using Pythagoras' identity in the right triangle

x² + 14² = 17²

x² + 196 = 289 ( subtract 196 from both sides )

x² = 93 ( take the square root of both sides )

x = \sqrt{93} ≈ 9.6 ( to the nearest tenth )
