Player 1 and player 2 are running laps around a field. Player 1 runs 1 lap every 4 minutes, while player 2 runs 1 lap every 15 minutes. If player 1 and player 2 begin their run at the same time and location on the field, in how many minutes will they meet to begin their next lap together?
Answer:
15 min
Step-by-step explanation:
if it takes Player 1 one min he will meet player two at there second lap after 15 min
If player 1 and player 2 begin their run at the same time and location on the field, In 60 minutes will they meet to begin their next lap together.
What is LCM?The LCM of any two is the value that is evenly divisible by the two given numbers.
Given,
Player 1 and player 2 are running laps around a field
Player 1 runs 1 lap every 4 minutes,
player 2 runs 1 lap every 15 minutes
We need to find in how many minutes will they meet to begin their next lap together
We need to find the LCM of 4 and 15 to find the answer
4: 4, 8,12,16, 20,24,28,32,36,40,44,48,52,56,60
15: 15,30,45,60
The least common multiple of 4 and 15 is 60.
The two players meet at the same point after 60 minutes.
Hence If player 1 and player 2 begin their run at the same time and location on the field, In 60 minutes will they meet to begin their next lap together.

Which function displays this end behavior?
• As xapproaches negative infinity, y approaches positive infinity.
• As xapproaches positive infinity, yapproaches negative infinity.
A.) y = (x+ 2)^3 -9
B.) y = -2x^3-1
C.) y = -3x^3 + 4
D.) y = 3(x-1)^2
The functions that displays the behavior that as x approaches -∞, y approaches ∞ and as x approaches -∞, y approaches -∞ are:
Option B: [tex]y = -2x^3-1[/tex]Option C: [tex]y = -3x^3 + 4[/tex]How to find the value of the function as x approaches infinity(+ve or -ve)?If limits exist, we can take limits of the function, where x tends to -∞ or ∞, and that limiting value will be the value the function will approach.
Testing all the four functions listed for x tending to -∞ or ∞:
Case A: [tex]y = (x+ 2)^3 -9[/tex]1. For x approaching -∞
[tex]lim_{x \rightarrow -\infty} (y) = lim_{x \rightarrow -\infty} ((x+2)^3 - 9) = -9 + lim_{x \rightarrow -\infty} ((x+2)^3) \rightarrow - \infty[/tex]
(since cube of negative quantity is going to be negative)
Thus, function also tends to -∞. So this function doesn't satisfy first case, thus, we don't need to test other case as only that function is needed which can satisfy both the cases.
Case B: [tex]y = -2x^3-1[/tex]1. For x approaching -∞
[tex]lim_{x \rightarrow -\infty} (y) = lim_{x \rightarrow -\infty} (-2x^3 - 1) = -1 + lim_{x \rightarrow -\infty} (-2x^3) \rightarrow \infty[/tex]
(this time, negative sign was canceled by outer negative. So function approaches positive infinity as x approaches negative infinity.
2. For x approaching ∞
[tex]lim_{x \rightarrow \infty} (y) = lim_{x \rightarrow \infty} (-2x^3 - 1) = -1 + lim_{x \rightarrow \infty} (-2x^3) \rightarrow -\infty[/tex]
So function approaches negative infinity as x approaches positive infinity
Thus, the considered function behaves as needed.
Case C: [tex]y = -3x^3 + 4[/tex]Similar to above cases, we can see that negative sign and cube power will make this function go to positive infinity as x approaches negative infinity, and as x approaches positive infinity, the function will approach negative infinity.
Remember that finite constants added or subtracted from arbitrary large quantities(positive or negative infinity) can't affect them.
Case D: [tex]y = 3(x-1)^2[/tex]Here x is in square power, no matter if x approaches +ve or -ve infinity, the square term would make it positive. So this function cannot approach negative infinity.
Thus, only Option B and C are performing as needed. Therefore, the functions that displays the behavior that as x approaches -∞, y approaches ∞ and as x approaches -∞, y approaches -∞ are:
Option B: [tex]y = -2x^3-1[/tex]Option C: [tex]y = -3x^3 + 4[/tex]Learn more about limiting values of a function here:

What is the y-intercept of the quadratic function
f(x)= (- 8)(x +3)?
Answer:
-24
Step-by-step explanation:
The standard from of equation of a line is expressed as g(x) = mx+c where;
m is the slope
c is the y-intercept of the line.
Given the expression g(x)= (- 8)(x +3), rewriting in standard form first we have;
g(x)= (- 8)(x +3)
gx)= -8x - 24
On Comparing with g(x) mx+ c, we will see that;
c = -24
Hence the y-intercept of the quadratic function is -24
.The square of a real number c is 11 less than the square of 5.
In an earlier chapter we learned that
32=3⋅3=9
We said that 9 was the square of 3. The square of -3 is 9 as well
(−3)2=(−3)⋅(−3)=9
3 and -3 are said to be the square roots of 9.
All positive real numbers has two square roots, one positive square root and one negative square root. The positive square root is sometimes referred to as the principal square root. The reason that we have two square roots is exemplified above. The product of two numbers is positive if both numbers have the same sign as is the case with squares and square roots
a2=a⋅a=(−a)⋅(−a)
A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand.
a−−√
To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.
±9–√=±3
Zero has one square root which is 0.
0–√=0
Negative numbers don't have real square roots since a square is either positive or 0.
If the square root of an integer is another integer then the square is called a perfect square. For example 25 is a perfect square since
±25−−√=±5
If the radicand is not a perfect square i.e. the square root is not a whole number than you have to approximate the square root
±3–√=±1.73205...≈±1.7
The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers. The decimal form of an irrational number will neither terminate nor repeat. The irrational numbers together with the rational numbers constitutes the real numbers.
Example
irrationalnumber⇒19−−√≈4.35889...
rationalnumber⇒0.5=12
