No. A parallelogram has 2 sets of parallel lines, each the same length. This doesn't mean that the angles are perpendicular.

P(x)=x2-1;x=-2 find wheter the following zeroes of the pollynomials are indicated towsrds them

Talja [164]

Given:

The polynomial is:

$p(x)=x^2-1$

To find:

Whether $x=-2$ is a zero of the given polynomial or not.

Solution:

If $x=c$ is a zero of a polynomial, then $f(c)=0$ .

We have,

$p(x)=x^2-1$

Putting $x=-2$ in the given polynomial.

$p(-2)=(-2)^2-1$

$p(-2)=4-1$

$p(-2)=3$

Since $p(-2)\neq 0$ , therefore $x=-2$ is not a zero of the given polynomial.

A square is inscribed in a circle with a diameter of 12 cm. If a point in the circle is chosen at random, what is the probabilit

Daniel [21]

P(shaded) = A of circle - A of square all divided by total outcomes which is A of circle = pi r^2 = pi(6)^2 = 36pi
estimate the sides of the square, 12 minus 4 = 8
A of square = s^2 = 64
P= 64/36pi = 0.56 .Choice C
Hope this helps=)
