To find the least-squares solution of Ax=b, we can use the normal equations A^T Ax = A^T b. In this case, A is given as 1 1 1 -1 0 and b is not given. Therefore, we cannot compute the exact least-squares solution. However, assuming that b is a vector of appropriate dimensions, we can solve the normal equations to obtain the least-squares solution À. Using this solution, we can then compute the projection of b onto the column space of A using the formula projcol(A)(b) = A À.
The least-squares solution of Ax=b is the vector À that minimizes the distance between Ax and b in the Euclidean sense. This solution can be obtained by solving the normal equations A^T Ax = A^T b. In this case, we have A = 1 1 1 -1 0 and we need to find b. Since b is not given, we cannot compute the exact least-squares solution. However, assuming that b is a vector of appropriate dimensions, we can solve the normal equations to obtain À. Using this solution, we can then compute the projection of b onto the column space of A using the formula projcol(A)(b) = A À.

A certain population is initially 8,951 but declines by 8% every second. Find an exponential formula that gives the population as a function of time. What will be the population after half of a minute?
9514 1404 393
Answer:
734
Step-by-step explanation:
The growth factor is 1 -8% = 0.92. This is the base of the exponential formula. The multiplier is the initial value, so you have ...
p = 8951×0.92^t
When t=30, this evaluates to ...
p = 8951×0.92^30 ≈ 733.68
The population after half a minute will be about 734.

At the circus, a clown is shot from a cannon. This situation can be modeled by the function: h = – 16t2 + 45t + 15, where 'h' is height in feet and 't' is time in seconds. Height of the clown
Answer:
t = 3.11 seconds
Step-by-step explanation:
Given that,
At the circus, a clown is shot from a cannon. This situation can be modeled by the function :
[tex]h = -16t^2 + 45t + 15[/tex]
Where
'h' is height in feet and 't' is time in seconds
We need to find how long did it take for the clown to reach his highest point. It can be calculated as follows :
[tex]-16t^2 + 45t + 15=0[/tex]
We need to solve for t. It can be calculated as follows :
[tex]t=\dfrac{-45\pm \sqrt{45^2-4(-16)(15)} }{2(-16)}\\\\t=-0.301\ \text{and}\ 3.11\ s[/tex]
So, the required time is 3.11 seconds.

Penelope eats 4 chocolates per day, because in one day, 20 chocolates are in the box. Then, after 2 more days, 8 chocolates are eaten. That means, if she eats an even amount of chocolates, she eats 4 chocolates per day. To check this pattern, on the fourth day, there are 8 chocolates left. 12 - 8 = 4, and the pattern would continue. On the fifth day, 4 chocolates would be left, and on the sixth day, 0 chocolates would be left.

Step-by-step explanation:
Enola is a waitress at a restaurant. Each day she works, Enola will make a guaranteed wage of $35, however the additional amount that Enola earns from tips depends on the number of tables she waits on that day. From past experiences, Enola noticed that she will get about $8 in tips for each table she waits on. How much would Enola expect to earn in a day on which she waits on 20 tables? How much expect to make in a day when waiting on t tables?
Answer:
1. 195
2. Y= 8t +35
Step-by-step explanation:
Answer:
$195; y=8t+35
Step-by-step explanation:
You can make an equation to find out how much Enola earns a day:
y=8t+35 ––This shows that "y" is the earnings for the day, "8t" represents $8 per table, and the "+35" represents the guarenteed $35 a day.
To answer the first question, the replace t with 20: y=8(20)+35
y=160+35
y=195
*For the second answer, I would put the equation because you do not know the number of tables because it is unspecified.
***You can change the "y" to whatever if you need to
A number, n, decreased by 5, is equal to 3 times the number plus 1. Determine the number.
Answer:
-3
Step-by-step explanation:
A number, n, decreased by 5: n - 5
3 times the number +1 = 3*n + 1 = 3n + 1
3n +1 = n -5
Subtract 1 from both sides
3n = n - 5 - 1
3n = n - 6
Subtract 'n' from both sides
3n - n = -6
2n = -6 {Divide both sides by 2}
n = -6/2
n = -3
The number = - 3
Vertical angles are a pair of opposite angles made by two intersecting lines and the angles are _________. *
2 points
Equal to each other
Equal to 90°
Equal to 180°
Equal to 360°
Answer:
[tex] \boxed{ \large{ \underline{\tt{Equal \: to \: each \: other}}}}[/tex]
Step-by-step explanation:
When two lines interesect , the angles formed opposite to each other are called vertically opposite angles. Vertically opposite angles [ V.O.A ] are always equal to each other.
Refer to the attachment! In the given figure , [tex] \angle[/tex] p and [tex] \angle[/tex] s are opposite to [tex] \angle[/tex]r and [tex] \angle[/tex]q respectively. Therefore [tex] \angle[/tex]p and [tex] \angle[/tex]r are vertical angles. Similarly , [tex] \angle[/tex]s and [tex] \angle[/tex]q are also vertical angles.
Hence , Our final answer : Vertical angles are a pair of opposite angles made by two intersecting lines and the angles are equal to each other .

Which is an example of a function?
the distance to school and the time you spend at school
the price of a piece of cloth and the length of the cloth
the price of a movie ticket and the height of the customer
the time it takes to mow a lawn and the age of the person mowing the lawn
Answer:
The price of a piece of cloth and length of cloth.
Step-by-step explanation:
A function must be measurable, attainable, and reasonable and the variables must complement each other
Measuring the distance to and time spend at school doesnt complement each other
The price of a movie ticket doesn't change based on height
Mowing a lawn doesnt matter how old you are
The price of cloth can change based on how long or short the cloth is.Shorter clothes are cheaper, while Longer clothes are more expensive.
Answer:
The example of a function is:
The price of a piece of cloth and the length of the cloth.
Step-by-step explanation:
We know that a function is a relation in which each element of a set is mapped to a single element of the other set.
i.e. an element has just one image.
1)
The time it takes to mow a lawn and the age of the person mowing the lawn.
This is not a example of function since, the time taken by two person's of different age may be same to mow a lawn.
This means that there is more than one image of a single element i.e. time.
2)
The distance to school and the time you spend at school.
The time one spend at school at different days may be different even if the distance to school is same.
3)
The price of a movie ticket and the height of the customer.
Two person's with different height will buy a movie ticket at the same cost.
Hence, this relation won't be a function.
4)
The price of a piece of cloth and the length of the cloth.
As we know that the price of a cloth is fixed according to the length.
Hence, the relation is a function.
( As corresponding to each price we have a unique length if a piece of clothing )

Answer:
[tex]\frac{3}{4}[/tex] of a sheet of paper
Step-by-step explanation:
Hi!
This isn't the easiest to explain with numbers but I'll do it with an example instead.
If you had 60 cookies and had to split it equally with you and one of your other friends, how would you do it?
You would do [tex]\frac{60}{2}[/tex], right? Because you have 60 cookies and you're dividing it amongst 2 people.
It's the same idea here!
We take the number of sheets of paper, and we divide it by the number of people we have to share it with.
so we do [tex]\frac{3}{4}[/tex]. You don't even have to simplify in this case because this is a fraction and this is the simplest form of this fraction as well
