Answer: 18 cubic units

Step-by-step explanation:

You can count the number of units on each side, one for height, which is 3 units, one for width, also 3, and one for length, 2 units. Volume is height*length*width, so 3*3*2 is 18.

Find the zeros (roots) of the following equations. f(x) = 2x5 - 9x4 + 12x3 - 12x2 + 10x - 3 = 0

Talja [164]

Hi,
$f(1)=2*1^5-9*1^4+12*1^3-12*1^2+10*1-3\\
=2-9+12-12+10-3\\
=0\\

f(x)=(x-1)(2x^4-7x^3+5x^2-7x+3)\\


g(x)=2x^4-7x^3+5x^2-7x+3\\

g(3)=2*3^4-7*3^3+5*3^2-7*3+3\\
=162-189+45-21+3\\
=0\\

g(x)=(x-3)(2x^3-x^2+2x-1)\\

h(x)=2x^3-x^2+2x-1\\

h( \dfrac{1}{2} )=2* \dfrac{1}{8} - \dfrac{1} {4}+1-1\\
=0\\

h(x)=(2x-1)(x^2+1)\\


f(x)=(x-1)(x-3)(2x-1)(x+i)(x-i)\\


$
Roots are 1,3,0.5,i,-i.

Given that f(x) = x2 – 3x – 28 and g(x) = x - 7, find

gregori [183]

Answer:

$(f-g)(x)=x^2-4x-21$

Step-by-step explanation:

We are given the two functions:

$f(x)=x^2-3x-28\text{ and } g(x)=x-7$

And we want to find:

$(f-g)(x)$

This is equivalent to:

$=f(x)-g(x)$

Substitute:

$=(x^2-3x-28)-(x-7)$

Distribute:

$=x^2-3x-28-x+7$

Rearrange:

$=(x^2)+(-3x-x)+(-28+7)$

Hence:

$(f-g)(x)=x^2-4x-21$

What does cpctc represent and when would you use it

faltersainse [42]

CPCTC represents is a succinct statement of a theorem regarding congruent trigonometry, defined as triangles either of which is an isometry of the other. CPCTC states that if two or more triangles are congruent, then all of their corresponding angles and sides are congruent as well. CPCTC is useful in proving various theorems about triangles and other polygons.
