NEED HELP. WILL MARK BRAINLIST. DO NOT SPAM

Mathematics
1 answer:
Tcecarenko [31]3 years ago
5 0

Answer:

  a) x = {-2, 1, 3} are the zeros

  b) y = (x +2)(x -1)(x -3)

  c) y = x^3 -2x^2 -5x +6

Step-by-step explanation:

a) The zeros are the values of x where the graph crosses y=0. Those values are x = -2, x = 1, x = 3.

__

b) If "a" is a zero, then (x-a) is a factor. The factored polynomial is ...

  y = (x +2)(x -1)(x -3)

__

c) This can be multiplied out using the distributive property several times.

  y = (x +2)(x(x -3) -1(x -3))

  = (x +2)(x^2 -3x -x +3)

  = (x +2)(x^2 -4x +3)

  = x(x^2 -4x +3) +2(x^2 -4x +3)

  = x^3 -4x^2 +3x +2x^2 -8x +6

  y = x^3 -2x^2 -5x +6

_____

The supplied graph apparently scales this vertically by a factor of 1/2, since its y-intercept is at (0, 3), not (0, 6).

Find the equation of the line The line has a slope of 1.3 and passes through the point (-2.3, -3.2)
irga5000 [103]

Answer:

y=1.3 x - 0.21

Step-by-step explanation:

y = (slope) \times x + (constant)

set (-2.3,-3.2) in above

- 3.2 = 1.3 \times ( - 2.3) + c

then c=-0.21

babunello [35]

Answer:

e║f.

Step-by-step explanation:

1) the pointed vectors of the given lines are:

for line e: (3-10;5-8)=(-7;-3);

for line f: (10-3;4-1)=(7;3);

2) -7/7=-3/3=-1, it means the lines are parallel.

Find the surface area of a cylinder with the following dimensions. Use 3. 14 for $. Round your answer to the nearest
kupik [55]

Answer:

b

Step-by-step explanation:

r=d/2=11.4/2=5.7

slant surface area=2πr*h=11.4×3.14×4.4=157.5024 cm^2

area of base and top=2(πr²)=2×3.14×(5.7)²=204.0372 cm²

total surface area=157.5024+204.0372=361.5396=361.5 sq. cm

1. Evaluate -3x^3 -2y^2 when x=-5 and y =3
-Dominant- [34]

Answer:

357

Step-by-step explanation:

A) We replace x = - 5 and u = 3 into -3x^3 -2y^2

and we have -3x^3 -2y^2= -3*(-5)^3 -2*3^2= -3*(-125)- 2*9

or -3x^3 -2y^2 = 375-18= 357

The answer is 357.

B) Replace h = -2 into h^2-3h+2

we have h^2-3h+2 = (-2)^2 -3*(-2) +2 = 4 +6 + 2= 12

The answer is 12

Have a good day.
