From the division of quadrants in the xy-plane, it is found that letter K represents the second quadrant.
What are the signals of the coordinates in each quadrant?There are four quadrants of points (x,y), and their signals are given as follows:
Quadrant 1: x is positive(left of y-axis) and y is positive(above the x-axis).Quadrant 2: x is negative(right of y-axis) and y is positive(above the x-axis).Quadrant 3: x is negative(right of y-axis) and y is negative(below the x-axis).Quadrant 4: x is positive(left of y-axis) and y is negative(below the x-axis).In this problem, we want Quadrant 2, in which:
x is negative, that is, to the left of the y-axis.y is positive, that is, above the x-axis.Hence:
Letter K represents the second quadrant.

A pizza can be shared by (y + 6) friends. If there are (y2 + 6y + 8) pizzas, which expression represents each friend’s share?
Given that
There are (y^2 + 6y + 8) pizzas and it is to be shared among (y + 6) friends.
Explanation -
So to find each friend's share we have to use long division method.
On dividing it we have
Here the remainder is 8.
So the solution is y + 8/(y+6).If there are initially 5000 bacteria in a culture, and the number of bacteria triple each hour, the number of bacteria after t hours can be found using the formula y = 5000(3)^t. How long will it take the culture to grow to 80,000? Round to the nearest tenths.
Then it will take approximately 6.3 hours for the culture to grow to 80,000 bacteria
The given formula for the number of bacteria in a culture after t hours is:y = 5000(3)^tWe are required to find the number of hours it will take the culture to grow to 80,000.
This can be done by setting y equal to 80,000 and then solving for t.5000(3)^t = 80,000
Divide both sides by 5000:3^t = 16Now, we need to solve for t by taking the logarithm of both sides.
However, it is easier to use logarithmic properties to simplify the equation first.3^t = 2^4
Raise both sides to the power of (1/log3):log3(3^t) = log3(2^4)t = 4/log3(2)Using a calculator, log3(2) ≈ 0.631, so:t ≈ 4/0.631 ≈ 6.3.

It takes Evelyn, traveling at 36 mph, 45 minutes longer to go a certain distance than it takes Ricky traveling at 72 mph. Find the distance traveled.
If Speed = dist/time, then;
dist = speed * time
We also know that both of them travel the same distance, so we equate the distance travelled to each other
36 * x+45 = 72 * x
36x + 1620 = 72x
72x - 36x = 1620
36x = 1620
x = 1620/36

Step-by-step explanation:
Faith is working two summer jobs, making $13 per hour lifeguarding and $12 per hour washing cars. Last week Faith worked a total of 12 hours and earned a total of $150. Write a system of equations that could be used to determine the number of hours Faith worked lifeguarding last week (x) and the number of hours she worked washing cars last week (y).
if she worked "x" hours lifeguarding at $13 per hour, that means she earned a total of 13*x or 13x, if she worked washing cars for "y" hours at $12 per hour that means she made on those hours 12*y or 12y, and we know that whatever their sum combined is a grand total of $150.
Last week she worked a total of 12 hours doing both, namely x + y = 12.
\(\begin{cases} 13x+12y &= 150\\ x + y &= 12 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{using the 2nd equation}}{x +y = 12}\implies y = 12 -x \\\\\\ \stackrel{\textit{substituting on the 1st equation}}{13x+12(12-x) = 150}\implies 13x+144-12x = 150\implies x + 144 = 150 \\\\\\ \boxed{x = 6}~\hfill \stackrel{\textit{we know that}}{y = 12 -x}\implies \boxed{y = 6}\)
A motorboat travels 116 kilometers in 4 hours going upstream. It travels 164 kilometers going downstream in the same amount of time. What is the rate of the
boat in still water and what is the rate of the current?
Rate of the boat in still water:
Rate of the current:
9514 1404 393
Answer:
boat: 35 km/hcurrent: 6 km/hStep-by-step explanation:
Let b and c represent the rates of the boat and current, respectively. Then the upstream rate is ...
speed = distance/time
b -c = (116 km)/(4 h) = 29 km/h
b +c = (164 km)/(4 h) = 41 km/h
Adding these equations gives ...
2b = 70 km/h
b = 35 km/h
Substituting into the first equation, we have ...
35 -c = 29
c = 6
Rate of the boat: 35 km/h.
Rate of the current: 6 km/h

What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given:
The triangles are congruent.
That means, their corresponding angles are also congruent.
In ΔJKL,
the sum of all the angles of the triangle is 180°.
So,
x²-2x + x + 29 + 3x + 52 = 180
x² + 2x - 99 = 0
Solving the quadratic equation,
x² +11x - 9x - 99 = 0.
x (x + 11) -9 (x + 11) = 0
x = 9 and x = -11
Here, we take x = 9.

What is surface area?The area occupied by a three-dimensional object by its outer surface is called the surface area.
A prism is a solid shape that is bound on all its sides by plane faces.
The surface area of prism is expressed as;
SA = 2B +pH
where B is the base area , p is the perimeter and h is the height.
1. SA = 2B +ph
B = 1/2 × 6 × 8

p = 6+8+10 = 24m
h = 12m
SA = 2 × 24 + 24 × 12
= 48 + 288
= 336 cm²
2. SA = 2( 3× 2) + 3× 7)+ 2 × 7)

A kilowatt-hour is about 3.6 x 10⁶joules.
A kilowatt-hour is about 1 3.6 x 10⁶ joules.
How to express the number as a fixed-point notation?From the question, we have the following parameters that can be used in our computation:
A kilowatt-hour is about 3.6 x 10⁶joules.
The above statement means that we convert 3.6 x 10⁶joules from joules to kilowatt-hour
Using the above as a guide, we have the following:
The given parameter can be represented using the following equation
3.6 x 10⁶joules = x kilowatt-hour
Rewrite as
x kilowatt-hour = 3.6 x 10⁶joules
As a general rule of conversion, we have
1 kilowatt-hour = 3.6 x 10⁶joules
So, we have the following representation
x kilowatt-hour = 1 kilowatt-hour

A negative number on the x-axis (-a, b) would move in what direction?
A positive number on the x-axis (+a, b) would move in what direction?
A negative number on the y-axis (a, -b) would move in what direction?
A positive number on the y-axis (a, +b) would move in what direction?
Please answer for points and brainliest!
a) A negative number on the x-axis (-a, b) would move in the left direction by one unit.
To find out why, check point (0, b) on the y-axis and point (-a, b) on the x-axis.
The distance between these two points is a unit, meaning that the point (-a, b) is one unit to the left of the point (0, b).
b) A positive number on the x-axis (+a, b) would move in the right direction by a unit.
Again, let's look at the point (0, b) on the y-axis and the point (+a, b) on the x-axis.
The distance between the two points is also one unit, which means the point (+a, b) is one unit to the right of the point (0, b).
c) A negative number on the y-axis (a, -b) would move in the downward direction by b units.
Assume that point (a, 0) is on the x-axis and point (a, -b) is on the y-axis. The distance between them is b units, which means that the point (a, -b) is b units below the point (a, 0).
d) A positive number on the y-axis (a, +b) would move in the upward direction by b units.
Also, check the point (a, 0) on the x-axis and point (a, +b) on the y-axis. The distance between these two points is b units, which means that the point (a, +b) is b units above the point (a, 0).
