What it means that [If x is a factor of p(x), what is the value of k?]

kompoz [17]

Answer:

$k = -4$

Explanation:

Given

$P(x) = (3x^2 - 5)(x + k) - 20$

x is a factor

Required

Solve for k

x is a factor means that the polynomial can be divided successfully by x.

In other words, x is a zero of the polynomial.

i.e.

$x = 0$ and $P(x) = 0$

Substitute 0 for x in P(x)

$P(x) = (3x^2 - 5)(x + k) - 20$

$P(x) = (3*0^2 - 5)(0 + k) - 20$

$P(x) = (0- 5)(k) - 20$

$P(x) = (-5)(k) - 20$

$P(x) = -5k - 20$

Substitute 0 for P(x)

$0 = -5k - 20$

Collect Like Terms

$5k = - 20$

Divide both sides by 5

$k = -4$

A student places a set of books with a force of 25 n on a lab table with a force of 150 n. What is the normal force pushing upwa

abruzzese [7]

The normal force acting on the legs of the table is 175 N

The weight of the books is the force exerted by the books on the table, and it is given as:

$W =25N$

The force exerted by the table is given as:

$F = 150N$

The parameters above imply that:

The table and the books are stationary,
The force exerted by both act in the same downward direction.

So, the normal force acting on the legs of the table is calculated as follows:

$F_N =F +W$

Substitute known values

$F_N = 150N + 25N$

$F_N = 175N$

Hence, the normal force acting on the legs of the table is 175 N
