Find the characteristic polynomial and the eigenvalues of the matrix.
[5 3]
[-4 4]
Answer:
Step-by-step explanation:
Given the matrix
[5 3]
[-4 4]
The characteristic polynomial is expressed as |A - λI| = 0 where λ are the eigen values and I is am identity matrix A 2*2 identity matrix is expressed as;
[1 0]
[0 1]
Substitute into expression will give;
[tex]= \left[\begin{array}{cc}5&3\\-4&4\\\end{array}\right] - \lambda \left[\begin{array}{cc}1&0\\0&1\\\end{array}\right] = 0\\= \left[\begin{array}{cc}5&3\\-4&4\\\end{array}\right] - \left[\begin{array}{cc}\lambda &0\\0&\lambda \\\end{array}\right] = 0\\= \left[\begin{array}{cc}5-\lambda&3\\-4&4-\lambda\\\end{array}\right] = 0[/tex]
Find the determinant of the resulting matrix;
|A - λI| = (5- λ)(4- λ)- 3(-4) = 0
|A - λI| = 20-5 λ-4 λ+ λ²+12 = 0
|A - λI| = 20-9λ+λ²+12 = 0
-9λ+λ²+32 = 0
Rearrange;
λ²-9λ+32 = 0
Hence the characteristic polynomial is expressed as λ²-9λ+32 = 0
Get the eigen values by finding the roots of the equation;
λ = 9±√9²-4(1)(32)/2
λ = 9±√81-(128)/2
λ = 9±√-47/2
λ = 9±√-47/2
λ₁ = 9-√47 i/2 and λ₂ = 9+√47 i/2
45% of a school brought in permission slips for Skateland. If the school received 150 permission slips, how many students are there in the school?
Step-by-step explanation:
What is 45% of 150?
Y is 45% of 150
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 45% * 150
Converting percent to decimal:
p = 45%/100 = 0.45
Y = 0.45 * 150
Y = 67.5

2. A ladder 20 feet long leans a vertical building. If the bottom of the ladder slides away from the building
horizontally at a rate of 2 ft/sec, how fast is the ladder sliding down the building when the top of the
ladder is 12 feet above the ground?
-8/3 ft/s
Step-by-step explanation:We are given:
distance of the top of the ladder from the ground (h) = 12 ft
height of the ladder = 20 ft
rate of change of the distance of the base of ladder from the wall (dx/dt):
2 ft/s
Finding the distance of the base of the ladder from the wall:
From the Pythagoras's Theorem, we know that:
hypotenuse² = height² + base²
replacing the given values
20² = 12² + x²
400 = 144 + x²
x² = 256 [subtracting 144 from both sides]
x = 16 ft [taking the square root of both sides]
The rate of change of the height of the Ladder from the ground:
We know that:
h = 12 ft
([tex]\frac{dh}{dt}[/tex]) = ?
x = 16 ft
([tex]\frac{dx}{dt}[/tex]) = 2 ft/s
According to the Pythagoras's Theorem:
20² = x² + h²
differentiating both sides with respect to time
[tex]\frac{d(400)}{dt} = \frac{d(x^{2} + h^{2})}{dt}[/tex]
[tex]0 = \frac{d(x^{2})}{dt} + \frac{d(h^{2})}{dt}[/tex]
[tex]0 = \frac{d(x^{2})}{dx}(\frac{dx}{dt}) + \frac{d(h^{2})}{dh}(\frac{dh}{dt})[/tex]
[tex]0 = 2x(\frac{dx}{dt}) + 2h(\frac{dh}{dt})[/tex]
replacing the variables
[tex]0 = 2(16)(2) + 2(12)(\frac{dh}{dt})[/tex]
[tex]0 = 64 + 32(\frac{dh}{dt})[/tex]
[tex]-64 =32(\frac{dh}{dt})[/tex] [subtracting 64 from both sides]
[tex]\frac{-64}{32} =(\frac{dh}{dt})[/tex] [dividing both sides by 32]
[tex]\frac{dh}{dt} = \frac{-8}{3} ft/s[/tex]
Hence, the ladder will slide down at a speed of 8/3 feet per second

If f(x)=2x-3 find the following
f(7)=
f(-2)=
f(-4)=
Step-by-step explanation:
f(x)=2x-3
now,
f(7)=2× 7-3
=14-3
=11
f(-2)='-2×7-3
= -14-3
b= -17
f(-4)= -4×7-3
= -28-3
= -31
The value of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 respectively.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
Given,
f(x)=2x-3
f(7) so put x = 7
f(7) = 2(7) - 3
f(7) = 11
Now,
f(-2) so put x = -2
f(-2) = -2×7-3
f(-2) = -17
Now,
f(-4) so put x = -4
f(-4)= -4×7-3
f(-4) = -31
Hence,The value of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 respectively.

Step-by-step explanation:
first you would try to find the GCF of the two numbers, which is 28. to find this you need to divide the two numbers by the GCF, which may take a few tries. then you would have to divide those two numbers by the GCF. your answer should look like this: 28(3+1)
What is the rate of change ? Please help!
Answer:
It is 1000
Step-by-step explanation:
To find the unit rate, we divide y/x. In this case our y is the height (ft) and the x is the time(min).
If we divide 1000/1, we get 1000
If we divide 2000/2, we get 1000

Alyssa had the largest slice available and ate 1/4 of it
Bobby had the smallest slice available and ate 3/4 of it.
