Answer:
Surface Area = 283
Step-by-step explanation:
Radius = 3
Height = 12
Formula for suface area is SA= 2πrh+2πr^2
let "r" be for radius
let "h" be for height
SA=2*π*3*12+2*π*3^2
SA=282.74
round to the nearest ones spot and that will make the surface area = 283
Answer:
A. x ≤ 
Step-by-step explanation:
-9x + 2 > 18 or 13x + 15 ≤ -4
-9x > 16 or 13x ≤ -19
x >
or x ≤ 
From the choices given, only x ≤
proves to be correct answer.
I don't know the answer I need help on it as well
Yes, felt that. thanks and have a lovely day!:D
Answer:
isosceles obtuse triangle
Step-by-step explanation:
The attached graph shows a plot of the three lines.
The triangle is an isosceles obtuse triangle in the 2nd quadrant.
_____
It is convenient to let a graphing calculator plot these lines. If you're going to plot them by hand, it usually works best to choose values of the variables for the variable that has the largest coefficient (3 in two of the equations). That way, you're not trying to plot coordinates that contain fractions.
