The bottle rotates 180 degrees in 2 seconds.

I divided 270 by 3, which was 90. Then, I multiplied 90 by 2. Which was 180.<span />

270 / 3 = 90
90 sec per spin
then you multply by two for two spins

90x2=180

Answer is 180 per sec

It will take 24 minutes for Joe and Charmaine to meet again at the starting line.

[B] How many laps does Joe complete

Joe will complete 2 laps

[C] How many laps does Charmaine complete?

Describe the nature of the roots for this equation.<br> 3x^2+x-5= 0

m_a_m_a [10]

Answer:

<h2>This equation has no natural roots.</h2>

Step-by-step explanation:

$3x^2+x-5=0\\\\\text{Use the quadratic formula for}\ ax^2+bx+c=0\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\\text{For the given equation:}\\\\a=3,\ b=1,\ c=-5\\\\b^2-4ac=1^2-4(3)(-5)=1+60=61\\\\x=\dfrac{-1\pm\sqrt{61}}{(2)(3)}=\dfrac{-1\pm\sqrt{61}}{6}\notin\mathbb{N}$

Answer:

(n+3) × n =40

n^2 + 3n =40

n^2 + 3n - 40=0

(n+8)(n-5)=0

n=-8 or n=5

Please help ! posted picture of problem

For a linear function: The graph is a straight line
For a non-linear function: The graph is not a straight line

The given graph is not a straight line and is rather a curve with several turning points i.e several ups and downs. Hence the graph belongs to a Non-Linear Function.

A relation is non-function when it passes through same x value more than once. Since this cannot be observed in the given graph, the graph belongs to a function.

Therefore, the correct answer to this question is "Non-Linear Function"
