To find an area we use this equation:
a = r² · π
a = 8² · π
a = 64π
The answer is 64π
Hope this helps!! :)
Answer:
Step-by-step explanation:
price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00
4 years = 3×365 days + 366 days = 1461 days
cost of electricity = 1461 days × $0.06/day = $87.66
lifetime cost = purchase price + electricity + repairs
= $202.00 + $87.66 + 2·$29
= $347.66
Answer:
y=3x-5
Step-by-step explanation:
Slope intercept form is y=mx+b
m represents slope
b represents y-intercept
In the picture, 3 replaces m, so 3 is the slope of the line.
When (2,1) and (5,10) are graphed, the line intercepts -5 on the y axis.
-5 is the y-intercept.
So, (2,1) and (5,10) in slope-intercept form is 
Answer:
yes, the point (-1, 5) is in the solution set
Step-by-step explanation:
y ≥ 2x + 3
Is 5 ≥ 2(-1) + 3? Yes
y + x > 0
Is 5 + (-1) > 0? Yes
