What are the zeroes of f(x) = x2 − x − 2? (4 points) a x = −2, 1 b x = 2, −1 c x = −2, −1 d x = 2, 1

Korvikt [17]

Answer:

x=2, x=-1

Step-by-step explanation:

f(x) = x^2 − x − 2

Set equal to zero

0 = x^2 − x − 2

Factor

What 2 numbers multiply to -2 and add to -1

-2*1 = -2

-2+1 =1

0=(x-2) (x+1)

Using the zero product property

x-2 =0 x+1 =0

x=2 x=-1

A triangle has two sides measuring 16 and 21. The included angle is 116°. What is the length of the side opposite the 116° angle

Crank

Answer:

Length of the side opposite to angle $116^{\circ}$ is 31.49

Step-by-step explanation:

Included angle can be defined as the angle in between two sides of the triangle.

So angle $116^{\circ}$ is in between sides 16 and 21.

Refer to the attachment for triangle diagram.

To find the length of opposite side, use cosine rule as follows

$a^{2}=b^{2}+c^{2}-2\:b\:c\cos\left(A\right)$

From the diagram, $b = 21,c = 16,\angle A=116^{\circ}$

Substituting the values in the formula,

$a^{2}=\left(21\right)^{2}+\left(16\right)^{2}-2\left(21\right)\left(16\right)\cos\left(116\right)$

Simplifying,

$a^{2}=441+256-225792\left(-0.44\right)$

$a^{2}=991.59$

Taking square root on both sides,

$\sqrt{a^{2}}=\sqrt{991.59}$

$a=31.49$

Therefore length of third side is 31.49
