The Parks and Rec department has an opening for a Solver of Linear Equations. Since Leslie is great at solving systems of linear equations she zealously offers to give all candidates a quick demonstration. She finds the LU factorization of a 2000 x 2000 matrix in 78125 seconds. She then takes another 25 seconds to apply both triangular substitutions (backward and forward) to solve the system of equations Mx = y for a given vector Y.
The candidates are supposed to estimate (without actually running any code) the time it takes to factorize and efficiently solve a similar system of linear equations Ax =b, where A is a square matrix with dimension 500, given 30 different right-hand side b vectors.
Matrix are used to show data in rows and columns
The estimated time to efficiently solve the square matrix A is 4907.8125 seconds
How to estimate the time to solve matrix AThe 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

1 liter is equal to 1,000 milliliters. How many milliliters are in 4 liters, 356 milliliters?
Answer:
4,356 milliliter
Step-by-step explanation:
If 1 liter = 1,000 milliliter
Formula: Multiply the volume value by 1000
Then, 4 liter = 4,000 milliliter
4,000 + 356=4,356
Hence, there are 4,356 milliliter in 4 liters, 356 milliliter.

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 ...

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

What is the length of minor arc SV? 20π in. 28π in. 40π in. 63π in.
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]
How can we use a full rotation?Whole circumference is covered by 360 degrees rotation.
How to find the relation between angle subtended by the arc, the radius and the arc length?[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]
Thus, the length of the minor arc SV is given by: Option A: [tex]20\pi \: \rm inches[/tex]

(1) D. Generalize Explain your procedure for calculating the profit
for Grooming USA. Suppose you wanted to calculate the profit
for several different scenarios. How could you simplify your
process?
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.

F represents the fee (in dollars) for climbing d meters.
F = 110 +0.12d
What is the increase in price for every 100 meters climbed?
Answer:
$12
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

The quadrilaterals JKLM and PQRS are similar.
Find the length x of PQ.
PLS HELP ME and dont give me the answer 2.4 its wrong
Answer:
[tex]x[/tex] = 2.8
Step-by-step explanation:
If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:
KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7
JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7
LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7
This shows that the ratio of KJ : QP = 5/7
KJ : QP = 2 : [tex]x[/tex] = 2 / [tex]x[/tex]
Therefore, [tex]\frac{2}{x}=\frac{5}{7}[/tex]
cross multiply: 14 = 5[tex]x[/tex]
Divide both sides by 5: [tex]x[/tex] = 2.8
A group of friends goes out to lunch and decides to split the bill. Their bill is $32. 50, plus they want to leave a 20% tip. The final amount will be split 4 ways. What is the amount each person will pay? $7. 50 $8. 15 $9. 20 $9. 75.
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
How to find the percentage from the total value?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

what are some equivalent ratios to 3:4.5
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.
