What dose a and x equal <br> 2³x 5- (√-1) a+ 5a - 3÷ x³

ser-zykov [4K]

The terms in which value of x when substituted leaves final value of p(x) = "0".

Here, x - 2 is factor. So value of x is 2.

Substituting value of x we get,

p(x) = x3 - 3x + 5a

p(2) = 2*3 - 3(2) + 5a

0+ 8-6 + 5a

-2 = 5a

a= -0.4

A circle has a radius of 5 in. A central angle that measures 150° cuts off an arc.

Slav-nsk [51]

Answer:

Part 1) The exact value of the arc length is $\frac{25}{6}\pi \ in$

Part 2) The approximate value of the arc length is $13.1\ in$

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference of a circle is equal to

$C=2\pi r$

we have

$r=5\ in$

substitute

$C=2\pi (5)$

$C=10\pi\ in$

step 2

Find the exact value of the arc length by a central angle of 150 degrees

Remember that the circumference of a circle subtends a central angle of 360 degrees

by proportion

$\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in$

step 3

Find the approximate value of the arc length

To find the approximate value, assume

$\pi =3.14$

substitute

$\frac{25}{6}(3.14)=13.1\ in$

determine the householder transformation that annihilates all but the first entry of the vector [1 1 1 1 ]t. specifically, if (

Stolb23 [73]

Answer:

v=a+ 2e1= [3 1 1 1] $x^{T}$ .

Step-by-step explanation:

Let a = $^{}$ $\left[\begin{array}{ccc}\\1&1&1\\\end{array}\right] ^{T}$ and we know that $\alpha$ =±║α║₂= 2.

As we have gone over in class, the formula for v is v= a- $\alpha$ e1

with the sign of chosen to avoid subtraction. This gives v=a+ 2e1= [3 1 1 1] $x^{T}$ .

Disclaimer ;The question is incomplete

Question:

Determine the Householder transformation that annihilates all but the first entry of the vector[1 1 1 1]>Specifically, if

$I-2vv^{T}/v^{T}v\left[\begin{array}{ccc}1\\1\\1\\1\end{array}\right]$ == $\left[\begin{array}{ccc}\alpha \\0\\0\\0\end{array}\right]$

what are the values of α and v?
