Answer:
If Ax-2x for some scalar λ, then x is an eigenvector of A because the only solution to this equation is the trivial solution.
Step-by-step explanation:
The eigen vector is linear transformation which is a non zero vector which changes due to scalar factor. The eigen factor value is denoted by lambda. The eigen vector is a latent vector.
PLEASE HELP DUE IN 40 MINS!! Using the Law of Sines, find the exact answer for x.
45°
X
30°
12
Answer:
Step-by-step explanation:
Sin(30) / X = Sin(45) / 12
use algebra to isolate X
1 / X = [ Sin(45) / 12 ] / Sin(30)
flip both sides
X = Sin(30) / [Sin(45) /12 ]
invert the denominator on the right side
X = Sin(30) * 12/ Sin(45)
Do you know what Sin(30) is off the top of your head?
and also Sin(45) ?
these are worth remembering... and you can b/c they are just
sin(0) = 0/2
sin(30) = 1 / 2
sin(45) = [tex]\sqrt{2}[/tex]/2
sin(60)= [tex]\sqrt{3}[/tex] / 2
sin(90) = [tex]\sqrt{4}[/tex] / 2 (aka 1)
note the numerators just counts up 0, 1, 2, 3, 4 :)
Cos works the same way but counts from 90° back to 0 but exactly like sin other wise, hence why Cos and Sin both = [tex]\sqrt{2}[/tex]/2 at 45 °
anyway
X = 1 / 2 * 12/ [tex]\sqrt{2}[/tex]/2
X = 3[tex]\sqrt{2}[/tex]
A=3
B= 2

Find the length and width of rectangle DMLG, and calculate its area.
PLZ CACULATE ITS AREA PLZ!!
Answer:240 square feet
Step-by-step explanation:length of rectangle DMLG
= DM = LG = (25 + 5) = 30 feet
width of rectangle DMLG
= ML = 8 feet
area of rectangle DMLG
= length × width
= 30 × 8
= 240 square feet
Answer: length of rectangle DMLG
= DM = LG = (25 + 5) = 30 feet
width of rectangle DMLG
= ML = 8 feet

The answer is the point that does not have y equal to 7.
Note: (x, y) = (7, -1)
The point (7, -1) shows an x-value of 7 and a y-value of -1.
Answer: (7, -1).

Answer:
3x -4y = 12
Step-by-step explanation:
The x- and y-intercepts are easily read from the graph as 4 and -3, respectively. Then the intercept form of the equation of the line is ...
x/(x-intercept) +y/(y-intercept) = 1
x/4 +y/(-3) = 1
Multiplying by 12 will clear the fractions and give the standard form:
3x -4y = 12

A theater sells t tickets at a price of p dollars each. The theater conducts a survey and predicts that if the price of each ticket is changed by $2, the number of tickets sold will change by 15 tickets. If n is the number of times the theater changes the ticket price by $2, the expression (p+ 2n) (t-15n) can represent the theaters's total revenue, in dollars. In this expression, what does (t-15n) represent?
A. the number of tickets that the theater will sell If the ticket price is increased by $2
B. the number of tickets the theater will sell if the ticket prices increased by $2n
C.the number of tickets the theater will sell if the ticket price is decreased by $15
Answer:
B
Step-by-step explanation:
You have to look at the second term to be sure of the meaning of t - 15n
What the given term says is that the total number of tickets sold (p) will decrease by 15 times the number of increases that there are.
The other term says that the cost of 1 ticket will increase that each ticket will increase by 2 dollars for each change in the ticket prices providing that change is 2 dollars.
C is out of the question. The information talks about 2 dollars per increase which is the first term.
A is not quite correct. It implies there is exactly 1 ticket increase. The crorect answer is the ticket increases can be a number of times (n)

Answer:
x = 6
y = 4
Step-by-step explanation:
Apply the angle bisector theorem to solve for x and y respectively.
✔️4/(9 - x) = 8/x
Cross multiply
4*x = 8(9 - x)
4x = 72 - 8x
Add 8x to both sides
4x + 8x = 72
12x = 72
12x/12 = 72/12
x = 6
✔️y/2 = 6/3
Cross multiply
3*y = 6*2
3y = 12
3y/3 = 12/3
y = 4
Q and T are the midpoints of the legs, RV and SU , of trapezoid RSUV. If RS=3y+12, QT=y+25, and UV=2y+32, what is the value of y?
The value of y for the expression 3y + 12 = 2y + 32 is 20.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Trapezoid RSUV.
RS and VU are parallel to each other.
This means,
RS = UV
Now,
3y + 12 = 2y + 32
3y - 2y = 32 - 12
y = 20
Thus,
The value of y is 20.

A pair of shoes originally costs $60. They are on sale for 25% off and sales tax is 7%. Cost is calculated by first applying the discount, then sales tax.
What is the total cost of shoes including tax?
Answer:
$48.15
Step-by-step explanation:
60.00 x 25% = $15.00
60.00 - 15.00 = $45.00
45.00 x 7% = $3.15
45.00 + 3.15 = $48.15
