Which identity is shown below: 12 • 1/12 = 1? Select one: a. multiplicative identity b. additive inverse c. additive identity d.
lutik1710 [3]
What you're seeing here is 12 being multiplied by its reciprocal. 12 * 1/12 = 1. This is an example of a multiplicative inverse; a multiplicative inverse is when you multiply a number by its reciprocal (1 over the number).

What is the multiple zero and multiplicity of f(x) = x3 + 10x2 + 25x?
elena-s [515]

Answer:

The multiple zero is x=-5.

The multiplicity is 2

Step-by-step explanation:

The given function is

f(x)=x^3+10x^2+25x

To find the zero of this function, we equate it to zero.

\Rightarrow x^3+10x^2+25x=0

We factor to obtain;

x(x^2+10x+25)=0

Observe that; the expression within the parenthesis is a perfect square.

This implies that;

x(x+5)^2=0

This implies that;

Either x=0 or (x+5)^2=0

(x+5)^2=0 has a multiple zero which is

x=-5 and its multplicity is 2.

Which is true?
makvit [3.9K]

A

Step-by-step explanation:

  1. To compare decimal numbers with the same whole digits, we have to check the numbers in the decimal points.
  2. We compare the numbers in the same decimal point in both numbers e.g the tenth, hundredth or thousandth decimal numbers.
  3. Whichever number has a bigger value for the lowest decimal point is the larger of the two.
  4. Whenever the lowest decimal point is the same between the two, go to the next decimal point and compare.

2.01 is less than 2.2 because the tenth decimal in the previous number (that of 0) is less than the tenth of the latter number (that is 2).

Find the approximate volume. Round to the hundredth when necessary.
Sedaia [141]

Answer:

Volume of Sphere is 33.51 ft^3

Volume of Cylinder is 37.7 m^2

Step-by-step explanation:

<u>Volume of a sphere formula:  V = 4 /3πr^3</u>

<u>Volume of a cylinder formula:  V = πr^2h</u>

<u />

<u>Step 1:  Find the volume of the sphere</u>

Since it shows the diameter, you need to divide 4 by 2 to get the radius:  2

V = 4/3*π*(2)^3

<em>V = 33.51 ft^3</em>

<em />

Answer:  Volume of Sphere is 33.51 ft^3

<u>Step 2:  Find the volume of the cylinder</u>

Since it shows the diameter, you need to divide 4 by 2 to get the radius:  2

V = π*(2)^2*(3)

<em>V = 37.7 m^2</em>

<em />

Answer:  Volume of Cylinder is 37.7 m^2
