Given:
The point P(-2, - 5) is rotated 90° about the origin, and then the image is reflected across the line x= 3.
To find:
The the coordinates of the final image P’’.
Solution:
The point P(-2, - 5) is rotated 90° about the origin. It means the point is rotated 90° counter clockwise about the origin
[tex](x,y)\to (-y,x)[/tex]
[tex]P(-2,-5)\to P'(-(-5),(-2))[/tex]
[tex]P(-2,-5)\to P'(5,-2)[/tex]
Then the image is reflected across the line x= 3.
[tex](x,y)\to (-x+6,y)[/tex]
[tex]P'(5,-2)\to P''(-5+6,-2)[/tex]
[tex]P'(5,-2)\to P''(1,-2)[/tex]
Therefore, the \coordinates of the final image P'' are (1,-2).

elana went to the store where you can scoop your own popcorn and buy as much as you want. She bought 10 ounces spicy popcorn for $2.50
how much dose popcorn cost per ounce
Answer:
each ouce is worth 25 cents
solution
in order to solve this you need to create proportions so
10 ounces
per $2.50
well you want this to be a unit rate so you would have
10 ounces = 1 ounce
2.50 x
to get to the unit rate, you can see that you divided 10 from 10 ounces so you would do the same to the bottom ...
2.50/10 which is equal to 0.25.

Tracy goes on a 3 day and night school band trip. There is no cost for travel and each band member only pays half the cost of the hotel room. However, each person is responsible for the cost of their own meals. His portion of the hotel bill is $49 per night and Tracy leaves a 10% tip for the maid service. Before tax, Tracy spends $32 per day on eating out plus 15% of this amount in tips. If Tracy spends a total of $280.74 on the band trip, what percent tax was Tracy charged on his food?
a.
6%
b.
7%
c.
8%
d.
9%
Answer:
D
Step-by-step explanation:
The service tax that is given on the food each day is 9 %.
What does service tax mean?
The government levies a service tax on particular service transactions carried out by the service provider. Suppose x% service tax is levied on a good on $n then the total amount that is to be paid is $(n(1+x/100)).
How to solve the problem?
Let the percent service tax that is charged on food be x%.
The situation is The total expenditure is $280.74 which is $49 per day on the hotel bill for 3 days on which a 10% tip was given for the maid services each day.
$32 was spent each day on food plus 15% of that amount was given as a tip each day.
And x% of $32 was given on tax.
Then, the equation that best represents the given situation is
280.74/3=49+(0.10)(49)+32+(0.15)(32)+(x/100)(32)
Then 93.58=90.7+(32)(x/100)
⇒32x=2.88×100
⇒x=288/32=9%
Thus, the service tax that is charged on the food each day is 9 %.

A store buys 8 sweaters for $72 and sells them for $288. How many profit does the store make per sweater?
Answer:
$27 per sweater
Step-by-step explanation:
To solve this, all we need to do is subtract the profit made by the amount the store bought the sweaters for:
288 - 72 = 216
Now, we can divide this number by 8 to find how much profit the store made per sweater:
216 / 8 = 27
So, the store made a profit of $27 per sweater.

Label the endpoints to round 49.672 to the nearest hundredth
Answer:
49.67 , you're welcome !
The round-off of the decimal number nearest to the hundredth is 49.67.
What is a round-off?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.
The accepted method for representing both integer and non-integer numbers is the decimal numeral system. Decimal notation is the term used to describe the method of representing numbers in the decimal system.
The given number is 49.672 will be rounded off as below:-
49.672 = 49.67
Therefore, the round-off of the decimal number nearest to the hundredth is 49.67.

Express each of these system specifications using predicates, quantifiers, and logical connectives, if necessary.
a. At least one console must be accessible during every fault condition.
b. The e-mail address of every user can be retrieved whenever the archive contains at least one message sent by every user on the system.
c. For every security breach there is at least one mecha- nism that can detect that breach if and only if there is a process that has not been compromised.
d. There are at least two paths connecting every two dis- tinct endpoints on the network.
e. No one knows the password of every user on the sys- tem except for the system administrator, who knows all passwords.
The system specification with predicates, quantifiers, and logical connectives are:
a. ∃C(x) ∀F(y) such that if F(y) is true, C(x) is true.
b. ∀U(x) (∃M(y) if ∀U(z), ∃M(w) is true, then E(x) is true).
c. ∀B(x) (∃D(y) D(y) can detect B(x) ↔ (∃P(z) ¬P(z) is true)).
d. ∀E(x, y) (∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect
E(x, y)).
e. ∀U(x) (¬P(x) is true, except for the system administrator who knows all passwords: ∀U(y) P(y) if y is the system administrator).
We have,
a.
Let C(x) be the predicate "x is a console" and F(x) be the predicate "x is a fault condition".
The specification can be expressed as:
∀F(x) ∃C(y) such that if F(x) is true, C(y) is true.
b.
Let U(x) be the predicate "x is a user" and M(x) be the predicate "x is a message".
The specification can be expressed as:
∀U(x) ∃E(y) such that if ∀U(x), ∃M(z) is true, E(y) is true.
c.
Let B(x) be the predicate "x is a security breach", D(x) be the predicate "x is a detection mechanism", and P(x) be the predicate "x is a compromised process".
The specification can be expressed as:
∀B(x) ∃D(y) such that D(y) can detect B(x) if and only if ∃P(z) such that ¬P(z) is true.
d.
Let E(x, y) be the predicate "x and y are distinct endpoints" and P(x, y) be the predicate "x and y are connected by a path".
The specification can be expressed as:
∀E(x, y) ∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect E(x, y).
e.
Let U(x) be the predicate "x is a user" and P(x) be the predicate "x knows the password".
The specification can be expressed as:
∀U(x) ¬P(x) is true, except for the system administrator who knows all passwords, which can be expressed as:
∀U(x) (x is the system administrator → P(x)).
Thus,
The system specification with predicates, quantifiers, and logical connectives are:
a. ∃C(x) ∀F(y) such that if F(y) is true, C(x) is true.
b. ∀U(x) (∃M(y) if ∀U(z), ∃M(w) is true, then E(x) is true).
c. ∀B(x) (∃D(y) D(y) can detect B(x) ↔ (∃P(z) ¬P(z) is true)).
d. ∀E(x, y) (∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect
E(x, y)).
e. ∀U(x) (¬P(x) is true, except for the system administrator who knows all passwords: ∀U(y) P(y) if y is the system administrator).

The answer is 3⁷ because when you are multiplying exponents with the same base, you keep the base and add the exponents. an example of this would be 4² x 4³. To simplify the expression you ignore the base, which is 4, and add the 2 and 3 to get 4⁵. So the answer to your question is 3⁷.
