Find the length of AC.

xeze [42]

Answer:

D. 8 cm

Step-by-step explanation:

Reference angle = 60°

Opposite side = BC = 8√3

Adjacent side = AC = ?

Thus:

Tan (60) = opp/adj

Tan (60) = (8√3)/AC

AC*Tan(60) = 8√3

Divide both sides by tan (60)

AC = (8√3)/Tan(60)

AC = (8√3)/√3 (tan 60 = √3)

AC = 8 cm

Fins the zeros, multiplicity, and effect on the graph of the function in

tekilochka [14]

Answer:

See explanation

Step-by-step explanation:

Zeroe of the function is such velue of x at which f(x)=0.

1. Consider the function $f(x)=-x(3x-2)^2 (x+9)^5.$

Zeros are:

$-x(3x-2)^2(x+9)^5=0\\ \\x=0\text{ or }x=\dfrac{2}{3}\text{ or }x=-9.$

Zero $x=0$ has multiplicity of 1, zero $x=\dfrac{2}{3}$ has multiplicity of 2, zero $x=-9$ has multiplicity of 5.

At $x=0$ or $x=-9$ the graph of the function crosses the x-axis, at $x=\dfrac{2}{3}$ the graph of the function touches the x-axis.

2. Consider the function $f(x)=x^3+10x^2+25x=x(x^2+10x+25)=x(x+5)^2.$

Zeros are:

$x(x+5)^2=0\\ \\x=0\text{ or }x=-5.$

Zero $x=0$ has multiplicity of 1, zero $x=-5$ has multiplicity of 2.

At $x=0$ the graph of the function crosses the x-axis, at $x=-5$ the graph of the function touches the x-axis.
