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.

Solve 7x + 2 < 9x - 4
Alexus [3.1K]

Answer:

\boxed{\bold{x>3}}

Step By Step Explanation:

Subtract 2 From Both Sides

\bold{7x+2-2

Simplify

\bold{7x

Subtract 9x From Both Sides

\bold{7x-9x

Simplify

\bold{-2x

Multiply Both Sides By -1 (Reverse Inequality)

\bold{\left(-2x\right)\left(-1\right)>\left(-6\right)\left(-1\right)}

Simplify

\bold{2x>6}

Divide Both Sides By 2

\bold{\frac{2x}{2}>\frac{6}{2}}

Simplify

\bold{x>3}

Find the surface area of the triangular prism below?
aleksley [76]

Answer:

10 divided by 3 = 3.33 for each side of the triangle.

2 x 6 = 12(area of two triangles)

10(height) x 3.33(area of one side of the triangle) x 3(three rectangles) = 99.9

Add given areas:

99.9 + 12 = 111.9 rounded = 112 cm^2

Please wait for more responses to be sure, thank you.

What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?
Sindrei [870]

Answer:

-5cd

Step-by-step explanation:

<u>Simplifying:</u>

  • -3cd - d(2c - 4) - 4d =          ⇒ parenthesis
  • -3cd - 2cd + 4d - 4d =         ⇒ simplify like terms
  • -5cd                                     ⇒ answer

The first choice is correct one.
