Matrix are used to show data in rows and columns

The estimated time to efficiently solve the square matrix A is 4907.8125 seconds

The given parameters are:

Matrix size = 2000 by 2000

Time = 78125 seconds

Substitution time = 25 seconds

The time to solve the matrix is dependent on the size of the matrix, while the substitution time is fixed

The size of the similar matrix is 500 by 500

The similar matrix is 1/16 smaller than the original matrix of 2000 by 2000.

So, the time to factorize the matrix is:

[tex]Time = \frac{1}{16} * 78125\ seconds[/tex]

[tex]Time = 4882.8125\ seconds[/tex]

The estimate of the time to solve the new matrix is the sum of the time to factorize it and the substitution time.

So, we have:

[tex]Total = 4882.8125\ seconds + 25\ seconds[/tex]

This gives

[tex]Total = 4907.8125\ seconds[/tex]

Hence, the estimated time to efficiently solve the square matrix A is 4907.8125 seconds

• Equation:

The system of two quadratic equation is

x² + 6x + 9 = 0

x² - 9 = 0

"A quadratic equation is an algebraic equation of the second degree in 'x'. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a'(a ≠ 0) and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term."

The solution of the first equation in the system is (- 3, - 3).

Therefore, the equation will be

[x - (- 3)] [x - (- 3)] = 0

⇒ (x + 3)(x + 3) = 0

⇒ (x + 3)² = 0

⇒ x² + 6x + 9 = 0

The solution of the second equation in the system is (3, - 3).

Therefore, the equation will be

[x - 3] [x - (- 3)] = 0

⇒ (x - 3)(x + 3) = 0

⇒ (x)² - (3)² = 0

⇒ x² - 9 = 0

Angles and arcs' lengths are related to each other. The length of the minor arc SV is given by: Option A: [tex]20\pi \: \rm inches[/tex]

Whole circumference is covered by 360 degrees rotation.

[tex]2\pi^c = 360^\circ = \text{Full circumference}[/tex]

The superscript 'c' shows angle measured is in radians.

If radius of the circle is of r units, then:

[tex]1^c \: \rm covers \: \dfrac{circumference}{2\pi} = \dfrac{2\pi r}{2\pi} = r\\\\or\\\\\theta^c \: covers \:\:\: r \times \theta \: \rm \text{units of arc}[/tex]

The complete problem specifies radius of the circle as 24 in. and

θ = 5pi/6

Thus, we get the measurement of the arc length that angle covers as:

[tex]r \times \theta \: \rm inches = 24 \times \dfrac{5\pi}{6} = 20\pi \: \rm inches[/tex]

Percent counts the number of a quantity compared to another quantity's 100 amount. The amount each person would pay is given by: Option D: $9. 75

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For the given case,

Bill for lunch = $32.50

Tip  = 20% of bill = [tex]\dfrac{32.50}{100} \times 20 = \dfrac{32.50}{5} = 6.50[/tex] (in dollars)

Total amount = Bill + Tip = $39

This amount has to be divided in 4 equal part.

Thus, each part of those 4 parts would be [tex]\dfrac{39}{4} = 9.75[/tex] (in dollars).

Thus, the amount each person would pay is given by: Option D: $9. 75

Answer:

Step-by-step explanation:

when d = 0,  F = 110

when d = 100, F = 110 + (0.12 x 100) = 122

when d = 200, F = 110 + (0.12 x 200) = 134

etc.

Therefore, increase in price for every 100 meters climbed = 134 - 122 = 122 - 110 = 12

Explanation:

Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.

The actual slope is ...

  slope = Δy/Δx = 6/2 = 3

Answer:

Step-by-step explanation:

First, find the unit rate. Divide 4.5 by 3 to get 1.5. 3:4.5 = 1:1.5. Then, multiply 1.5 by any number to get an equivalent ratio. For example, 1.5 times 6 = 9, so an equivalent ratio is 6:9. Or, 1.5 times 10 = 15, so another equivalent ratio is 10:15.

Answer:

$1,650 profit

Step-by-step explanation:

It cost $15 to groom one animal, if you groom 95 animals you would do 95 animals x $15 = $1,425 profit. If you groom 110 animals and charge $15 per animal you would do the same equation. 110 animals x $15 =  $1,650. The equation for this problem is the number of animals groomed X the cost to groom one animal.

Hope this helps!

Answer and Step-by-step explanation:

I will try the best I can :3

if she started with 6, the first point you would put is (0,6)

this is how the equation would look:

y=___+6

(Tip: the number on the right is the y-intercept and the one on the left is the slope)

Now to find the slope: m=

y-y / x-x

Let’s use points (0,6) and points (2,8)

Rewrite to find slope: 8-6 / 2-0              =                 2/2 or 1

Now the equation should be:

y=1x+6

Answer:

JL ≈ 3.1

Step-by-step explanation:

Using the cosine rule

with JL = k , JK = l , KL = j , then

k² = j² + l² - (2jlcosK )

   = 6² + 8² - ( 2 × 6 × 8 × cos20° )

    = 36 + 64 - (96cos20°)

    = 100 - 96cos20° ( take square root of both sides )

k = [tex]\sqrt{100-(96cos20)}[/tex] ≈ 3.1 ( to the nearest tenth )

that is JL ≈ 3.1
