Answer 1

Answer:

2/9, 2/7, 1/10, 1/6, 1/4, 1/7, 1/16, 5/3

Step-by-step explanation:

A: 2/3 divided by 3

2/3 : 3 = 2/3*1/3 = 2/9

B: 6/7 divided by 3

6/7 : 3 = 6/7 *1/3 = 2/7

C: 2/5 divided by 4

2/5 : 4 = 2/5*1/4 = 1/10

D: 5/6 divided by 5

5/6 : 5 = 5/6*1/5 = 1/6

E: 10/8 divided by 5

10/8 : 5 = 5/4 * 1/5 = 1/4

F: 4/7 divided by 4

4/7 : 4 = 4/7*1/4 = 1/7

G: 5/8 divided by 10

5/8 : 10 = 5/8*1/10 = 1/16

H: 20/6 divided by 2

20/6 : 2 = 10/3 * 1/2 = 5/3

Let A,B, and C be square invertible matrices of the same size. If C has no eigenvalue equal to -1, then (AB + ACB)^-1 is equal to:

a. B^-1 (I + C)^-1*A^-1
b. (I + C)^-1*B^-1*A^-1
c. A^-1B*(I + C)^-1
d. (I + C)^-1*BA^-1

Answers

AB + ACB = A (B + CB) = A (I + C ) B

Taking the inverse gives

(A (I + C ) B)⁻¹ = B ⁻¹ (I + C )⁻¹ A ⁻¹

so the answer is (A)

A,B, and C are square invertible matrices of the same size.The correct option is a. [tex]\(A^{-1}(I + C)^{-1}B^{-1}\)[/tex].

Given A, B, and C as square invertible matrices of the same size, we want to find [tex]\((AB + ACB)^{-1}\)[/tex].

Step 1: Factor out B from the expression inside the parentheses:

[tex]\(AB + ACB = B(A + AC)\)[/tex]

Step 2: Use the property that [tex]\((X + Y)^{-1} = Y^{-1}X^{-1}\)[/tex] for invertible matrices X and Y:

[tex]\((AB + ACB)^{-1} = (B(A + AC))^{-1} = (A + AC)^{-1}B^{-1}\)[/tex]

Step 3: Now, use the distributive property of matrix inversion, which states that [tex]\((XY)^{-1} = Y^{-1}X^{-1}\)[/tex] for invertible matrices X and Y:

[tex]\((A + AC)^{-1} = A^{-1}(I + C)^{-1}\)[/tex]

Step 4: Substitute this back into the expression from Step 2:

[tex]\((AB + ACB)^{-1} = (A + AC)^{-1}B^{-1} = A^{-1}(I + C)^{-1}B^{-1}\)[/tex]

So, the correct option is: a. [tex]\(A^{-1}(I + C)^{-1}B^{-1}\)[/tex]

Step-by-step explanation:

Benny invests $960 yearly into an account that pays 8% interest, compounded
annually. Determine the amount in Benny's account after 10 years.

Answers

Answer:

$2,072.56

Step-by-step explanation:

Compound interest formula is expressed as;

A = P(1+r) ^ n

A = 960(1+0.08) ^ 10

A = 960(1.08)^10

A = 960(2.1589)

A = 2,072.56

Hence the amount in Benny's account after 10 years is $2,072.56

Answers

Answer:

  A.  (3, 3)

Step-by-step explanation:

The coefficients of y are opposites, so adding the two equations will eliminate y.

  (x +2y) +(3x -2y) = (9) +(3)

  4x = 12 . . . simplify

  x = 3 . . . . . divide by 4

Using the first equation, we can find y:

  3 +2y = 9 . . . . . .substitute for x

  2y = 6 . . . . . . . .  subtract 3

  y = 3 . . . . . . . . . . divide by 2

The solution is (x, y) = (3, 3).

The price of the tennis racket was 200 dollars. However, the actual price of the tennis racket was 400 dollars. What is the percent error?

Answers

Given,

The price of the tennis rocket = $200

The actual price of the tennis racket was $400

To find,

The percentage error in the price of the rocket.

Solution,

The percentage error is calculated as :

% = (final value-actual value)/actual value × 100

[tex]\%=\dfrac{400-200}{400}\times 100\\\\=50\%[/tex]

So, the percent error is 50%.

A boat's crew rowed 15 kilometers downstream, with the current, in 1 hours. The return trip upstream, against the current, covered the same distance, and it took 3 hours. Find the crew's rowing rate in still water.

Answers

b and c are the speeds of the boat (in still water) and the current.

Traveling with the current, the boat goes b+c km per hour.
1 hour * (b+c km)/hour = 15 km
b+c = 15

Traveling against the current, the boat goes b-c km per hour.
3 hours * (b-c km)/hour = 15
b-c = 5

Add the two equations
b = 10 km per hour

What is the quadratic function?

In algebra, a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic, is a polynomial function with one or more variables in which the highest-degree term is of the second degree.

Here we have the two quadratic functions:

f(x) = 4(x - 3)²+ 6

g(x) = -2(x + 1)²+ 4

The x-value of the vertex is the value of x such that the first term becomes equal to zero, so for f(x) the vertex is at x = 3, and the y-value of the vertex is:

f(3) = 0 + 6 = 6

So the vertex is (3, 6)

For g(x) we can see that the vertex is at x = -1, and:

g(-1) = 0 + 4=4

So the vertex is at (-1, 4)

Also, you can see that for g(x) and f(x) the leading coefficients are of different signs. Meaning that f(x) opens upwards and g(x) opens downwards.

Hence, options 1,2 and three are correct answers.

A. (x - 1)2 + (y - 11)2 = 5
B. (x + 2)2 + (y - 7)2 = 5
C. (x - 1)2 + (y - 11)2 = 25
D. (x + 2)2 + (y - 7)2 = 25

Answers

The answer to your question is C.


step by step:

The equation of a circle with center at  [tex]C(-2, 7)[/tex]  and Point [tex]P(1, 11)[/tex] will be   [tex](x+2)^2+(y-7)^2=25[/tex] .

What is equation of a circle ?

Equation of a circle is written in the form [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex]   is the center and  [tex]r[/tex]  is the radius.

We have,

Center at  [tex]C(-2, 7)[/tex]

i.e. [tex]h=-2[/tex], [tex]k=7[/tex],

And

Point [tex]P(1, 11)[/tex]

i.e. [tex]x=1[/tex], [tex]y=11[/tex]

Now,

To determine Radius of the circle;

[tex]r^2=(x-h)^2+(y-k)^2[/tex]

[tex]r^2=(1-(-2))^2+(11-7)^2[/tex]

[tex]r=\sqrt{3^2+4^2} =\sqrt{25}[/tex]

[tex]r=5[/tex]

So, radius of the circle is [tex]5[/tex] .

Now,

Equation of a circle ;

[tex](x-h)^2+(y-k)^2=r^2[/tex]

[tex](x-(-2))^2+(y-7)^2=5^2[/tex]

[tex](x+2)^2+(y-7)^2=25[/tex]

So, the Equation of a circle is  [tex](x+2)^2+(y-7)^2=25[/tex] .

Hence, we can say that the equation of a circle with center at  [tex]C(-2, 7)[/tex]  and Point [tex]P(1, 11)[/tex]  is   [tex](x+2)^2+(y-7)^2=25[/tex] .

Answers

Answer:

The jacket increase by 25% in price.

Step-by-step explanation:

Given that:

Sale price of jacket = $210

New cost of jacket = $262.50

Change = New cost - Sale price

Change = 262.50 - 210 = $52.50

Percent increase = [tex]\frac{Change}{Sale\ price}*100[/tex]

Percent increase = [tex]\frac{52.50}{210}*100[/tex]

Percent increase = 0.25 * 100

Percent increase = 25%
