Answer:
3847
Step-by-step explanation:
To get your radius
diameter/2= 70/2=35.
Radius=35
Area=πr^2 =3.14x 35x35= 3846.5
approximately=3847
Rounding down the answer is.86
Answer:
amplitude = |-4| =4
period = 2 pi/3
phase shift = pi / 3
midline = 2
Step-by-step explanation:
f(x)=-4 cos (3x-pi)+2
The equation is in the form
f(x) = a cos (bx -c) +d where |a| is the amplitude
period is 2 pi /b
phase shift: c/b
midline = d
amplitude = |-4| =4
period = 2 pi/3
phase shift = pi / 3
midline = 2
Answer:
Step-by-step explanation:
<u>Given is the system of linear equations:</u>
<u>Convert both equations into slope intercept form:</u>
- nx + 3y = 6 ⇒ 3y = - nx + 6 ⇒ y = - 1/3nx + 2
- 12x - 6y = 0 ⇒ 6y = 12x ⇒ y = 2x
<u>The system has no solution if lines have equal slopes with different y-intercepts:</u>
