Find the zeros of the function. f(x) = 9x^3 + 18 x^2 - 135x

1 answer:

6 0

Where f(x)=0 is the zeros of the funciton

factor out the common factor of all of them which is 9x
f(x)=9x(x^2+2x-15)
what 2 numbers multiply to get -15 and add to get 2?
5 adn -3

f(x)=(9x)(x+5)(x-3)
set to zero
9x=0
x=0

x+5=0
x=-5

x-3=0
x=3

zeroes at x=-5, 0,3

SOMEONE ANSWER PLEASE The trapezoid below is made up of a square and a triangle The total area of the trapezoid

vladimir2022 [97]

Solution:

Note that:

Area of trapezoid = Area of triangle + Area of square = 575 m²
Area of triangle = 32.5 m²
Area of square = s²

Finding the area of the square:

32.5 + Area of square = 575 m²
=> Area of square = 575 - 32.5
=> Area of square = 542.5
=> s² = 542.5
=> s = √542.5 ≈ 23.29

The length of the square is 23.29 meters.

Greeley [361]

Answer:

Valid

Step-by-step explanation:

3(x-4)=x+4 Given

3x-12=x+4 Distribute

2x=16 Subtract x from both sides and add 12 to both sides

x=8 Divide each side by 2.

Show that if u+v and u-v are orthognal, then the vectors u and v must have the same length.

pashok25 [27]

Answer with Step-by-step explanation:

We are given that

u+ v and u-v are orthogonal

We have to prove that u and v must have the same length.

When two vector a and b are orthogonal then

$a\cdot b=0$

By using the property

$(u+v)\cdot (u-v)=0$

We know that

$(a+b)\cdot (a-b)=\mid a\mid^2-\mid b\mid^2$

$\mid u\mid ^2-\mid v\mid^2=0$

$\mid u\mid^2=\mid v\mid^2$

Magnitude is always positive

When power of base on both sides are equal then base will be equal

Therefore,

$\mid u\mid=\mid v\mid$

Hence, the length of vectors u and v must have the same length.

I need to find the derivative. I’m not very good at this so I am answer asap would be sosososo helpful

Bingel [31]

Answer:

See below.

Step-by-step explanation:

First, notice that this is a composition of functions. For instance, let's let $f(x)=\sqrt{x}$ and $g(x)=7x^2+4x+1$ . Then, the given equation is essentially $f(g(x))=\sqrt{7x^2+4x+1}$ . Thus, we can use the chain rule.
