Answer:

Amplitude = 4

Step-by-step explanation:

The general form of a sine curve would be $y=ASin(bx)$ where A is the <u>"amplitude"</u>, or the "tallness" or "shortness" of the graph.

Technically, amplitude is the absolute value of the number that is multiplied in front of "Sin". So the amplitude is 4.

<u>Note:</u> The negative sign in front of 4 plays the role of "flipping" the curve upside down.

1. Convert 60° to radians.

hram777 [196]

Answer:

60° = $\frac{\pi }{3}$ radians

Step-by-step explanation:

To convert from degrees to radians

radian measure = degree measure × $\frac{\pi }{180}$

Thus 60° in radian measure

= 60 × $\frac{\pi }{180}$ ( divide ( cancel) 60 and 180 by 60 )

= $\frac{\pi }{3}$

If n lines are drawn in a plane, how many regions do they separate the plane into? induction

grandymaker [24]

Hello,

Let's assume i the number of lines,
u(i) the number of regions:

$u_0=1\\\\
u_1=2=1+1=1+u_0\\\\
u_2=4=2+u_1\\\\
u_3=7=3+u_2\\\\
u_4=11=4+u_3\\\\
u_5=16=5+u_4\\\\
...\\\\
\boxed{u_{n+1}=(n+1)+u_{n}}\\\\

u_{n+1}=(n+1)+n+(n-1)+...+1+u_0\\\\

\boxed{u_{n+1}= \dfrac{(n+1)*(n+2)}{2}+1 }$

Help please!!! Pre-calculus

Anvisha [2.4K]

Answer:

P ( 3, - pi/3 + 2 pi n) or P ( -3 , -pi/3 + pi(2 n +1))

Step-by-step explanation:

P ( 3, - pi/3)

We can circle 2pi n around the circle and be back at the same polar coordinate

P ( 3, - pi/3 + 2 pi n)

or we can flip the radius to a negative and add pi to the theta

P ( -3, - pi/3 + pi)

Then we can circle 2pi n around the circle and be back at the same polar coordinate

P ( -3 , -pi/3 + 2 pi n +pi)

P ( -3 , -pi/3 + pi(2 n +1))
