Find algebraically the zeros for p(x)=x^3+x^2-4x-4

Mathematics
1 answer:
raketka [301]4 years ago
3 0
One  zero is - 1
because p(-1) =  (-1)^3 + (-1)^2 -4(-1)- 4 = 0
So one factor of p(x) is x + 1
Dividing  p(x) by  x + 1  gives the quotient
x^2 - 4
x - 2)(x + 2) = 0

x = 2, -2


The zeroes are -2,-1 and 2

An attacker at the base of a castle wall 4 m high throws a rock straight up with speed 7.5 m/s from a height of 1.5 m
Sergeu [11.5K]

Answer:

a) Yes, b) v\approx 2.686\,\frac{m}{s}, c) v_{o} \approx 7.002\,\frac{m}{s}

Step-by-step explanation:

a) The maximum height reached by the rock is:

\Delta y = \frac{\left(0\,\frac{m}{s} \right)^{2}-\left(7.5\,\frac{m}{s} \right)^{2}}{2\cdot \left(-9.807\,\frac{m}{s^{2}} \right)}

\Delta y = 2.868\,m

y = 1.5\,m + 2.868\,m

y = 4.368\,m

Yes, the rock will exceed the top of the wall.

b) The speed when the rock reaches the top of the wall:

v = \sqrt{\left(7.5\,\frac{m}{s} \right)^{2}+2\cdot \left(-9.807\,\frac{m}{s^{2}} \right)\cdot (4\,m-1.5\,m)}

v\approx 2.686\,\frac{m}{s}

c) The initial speed required so that stone does not exceed the top of the wall is:

v_{o} = \sqrt{\left(0\,\frac{m}{s} \right)^{2}-2\cdot \left(-9.807\,\frac{m}{s^{2}} \right)\cdot (4\,m-1.5\,m) }

v_{o} \approx 7.002\,\frac{m}{s}

Why did most Americans reject Marxism in the early 1900s? They believed that a government-run economy was best for all. They bel
Nadusha1986 [10]

Answer:

They believed in a system owned and run by the individual

Step-by-step explanation:

In the early 1900's the majority of the Americans rejected the Marxist ideology, and they saw it as usurpation of their country and its foundations. The majority of the Americans favored the capitalism, and they saw their country as the country of opportunities where everyone can achieve everything if the person is smart enough and works hard enough. The Marxism suggested the total opposite of it, that everyone should be equal, have the same earnings, there's no prosper on a career level, so for the Americans was not attractive, and we can comfortably say that they made the right choice considering what happened in the countries that adopted this ideology.
