Answer:
Q' (- 2, - 6 )
Step-by-step explanation:
a translation of 4 units left is in the x- direction and means subtract 4 from the x- coordinate.
a translation of 3 units down is in the y- direction and means subtract 3 from the y- coordinate.
Q (2, - 3 ) → Q' (2 - 4, - 3 - 3 ) → Q' (- 2, - 6 )
pH is measured on a scale of 0 to 14 and refers to the concentration of an acid or base in water. The recommended pH for a swimming pool is 7.2 to 7.8. Write an inequality that represents the recommended pH of the swimming pool.
Answer:
[tex]7.2\leq pH\leq 7.8[/tex]
(any variable can be used in place of "pH")
Step-by-step explanation:
Since the pH has to be between 7.2 and 7.8, it is more than 7.2 and less than 7.8.
The less than equal to sign was used because the pH can also equal 7.2 and 7.8.
Like mentioned, any variable like x can be used instead of the "pH" I put in the equation, but make sure to define your variable.

4) A bag contains one red marble and two
green marbles. You randomly pick a
marble and keep it to play with. Then
your friend picks a marble from the bag.
Answer:
{(Red , Green) ; (Green , Red) ; ((Green , Green)}
Step-by-step explanation:
Here ,we notice that we draw two marbles without replacement.
Then
The possible outcomes are :
• Red then Green
• Green then Red
• Green then Green
NOTE : we can’t have the outcome Red then Red ,because if you pick a red marble and keep it to play with. Then your friend has only the choice of picking a Green marble from the bag.
Therefore,
The sample space is {(Red , Green) ; (Green , Red) ; ((Green , Green)}.
Rewrite 8x + 64 using a common factor.
8x(x + 64)
8x(x + 8)
8(x + 64)
8(x + 8)
The expression (8x+64) can be rewritten as a common factor as 8(x+8).
According to the question,
We have the following expression:
(8x+64)
It is to be noted that a common factor is such a number including a variable that it can completely divide a term. For example, in this expression, 8 is such a number that it can divide both 8x as well as 64.
(This can be better understood using more examples. For example, 4 is a common factor in 4x+24 and 5 is a common factor in 5x+30.)
Now, taking 8 as a common factor:
8 (x+8)
Hence, the correct expression is D (the fourth one).

It takes 15 over 2 minutes to fill an empty aquarium to a depth of 3 over 5 meters. What is the unit rate in minutes per meter? Write your answer as a fraction or a mixed number in the simplest form. pls answer
The unit rate in minutes per meter is 12½ min./m if it takes 15 over 2 minutes to fill an empty aquarium to a depth of 3 over 5 meters.
It takes 15/2 mins to fill an empty aquarium to a depth of 3/5 meters.
In a situationism like this we can make a equation such as
15/2 = 3/5
Lets multiply 5 in both sides
15/2 × 5= 3/5 × 5
75/2 = 3
Now lets divide both sides with 3
(75/2)/3 =3/3
25/2 = 1
Thus, the unit rate in minutes per meter is 12½ min./m if it akes 15 over 2 minutes to fill an empty aquarium to a depth of 3 over 5 meters.
What is unit rate?Which car goes faster, a car that travels 42 miles in three hours or a car that travels 132 miles in seven hours? The solution is determined by the unit rate of each automobile. Rather than comparing the distances traveled in two or seven hours, compare how far each car drives in one hour.
A unit rate is just a ratio of two unit values, with the denominator always being one. This enables easy comparison of data values. To mention a few, common unit rates in the real world include miles per hour (MPH), price per unit, miles per gallon (MPG), revolutions per minute (RPM), and pay per year.

for a sequence(chapter3) of numbers, suppose that you attach 1, then 2, then 3, and so on up to n. what is the big-o time analysis for the combined time of attaching all n numbers?
The big-o time analysis for the combined time of attaching all n numbers i O(n).
The big-O running time gives the relationship between the steps taken for the algorithm and its running time. it is denoted by O(.), where . refers to the some f(n). f(n) is determined by the way of the algorithm in each step.
Here, we attach 1, then 2,then 3 and so on up to n to make a sequence of numbers. So at a time, only 1 number is attached and therefore one step of the algorithm is working. So we can say that the big-O time analysis for the combined time of attaching all n numbers is O(n).

$(500 x3 + 200 x2 + 600 x) ---(1)
If r= 2%, then x=(1 + 2/100), , substituting the value of x in (1)

A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator
descends 6 feet per second. The elevator for the miners descends 15 feet per second. One day, the equipment elevator begins to descend. After 33 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 12 seconds? At that time, which elevator is deeper?
i. The equipment elevator is at a depth of 270 feet (-270 feet), while the miners elevator is at a depth of 180 feet (-180 feet) below the surface.
ii. The equipment elevator is deeper than that of the miners elevator.
The speed of an object is the rate at which the object moves.
speed = distance / time.
Thus,
Speed of the equipment elevator = 6 feet per second
Speed of the miners elevator = 15 feet per second.
Time of descent of the equipment elevator = 33 + 12
= 45 seconds
So that, the distance of the elevator at this time is;
⇒ distance = speed x time
= 6 x 45
= 270 feet
distance = - 270 feet
The distance of the miners elevator after 12 seconds is:
⇒ distance = speed x time
= 15 x 12
= 180 feet
distance = - 180 feet
Thus after another 12 seconds, the equipment elevator is at a depth of 270 feet (-270 feet), while the miners elevator is at a depth of 180 feet (-180 feet) below the surface.
Therefore, the equipment elevator is deeper than that of the miners elevator.

A client asked Nathan to design a rectangular garden with an area of 22 square feet. The client also requested that the length of the garden be eight feet less than seven times the width
The length of the rectangular garden is 9.01 feet and width of the garden is 2.43 feet, if its area is 22 square feet.
Let the width of the garden be x units.
According to the given question.
The area of the rectangular garden is 22 square feet.
Also, the length of the garden be eight feet less than seven times the width.
⇒ length of the garden = 7x - 8
Thereofore, the area of the rectangular garden is given by
22 = x(7x - 8)
⇒ 22 = 7x^2 - 8x
⇒ 7x^2 - 8x - 22 = 0
⇒ x = [tex]\frac{8 \pm \sqrt{64 + 616} }{14}[/tex]
⇒ x = [tex]\frac{8 \pm \sqrt{680} }{14}[/tex]
⇒ x = [tex]\frac{8\pm 26}{14}[/tex]
⇒ x = 8 + 26/14
⇒ x = 34/14
⇒ x = 2.43 feet
So,
the length of the rectangular garden = 7(2.43) - 8 = 9.01 feet
Hence, the length of the rectangular garden is 9.01 feet and width of the garden is 2.43 feet, if its area is 22 square feet.
