Answer:
Length of arc is 2π
Step-by-step explanation:
Length of arc=¤/360 x 2πr
Where:
¤=angle
r=radius
length of arc=90/360 x 2xπx4
Length of arc=1/4 x 8π
Length of arc=8π ➗ 4
Length of arc=2π
I believe the answers are C. Acute (all angles less than 90 degrees) and E. Scalene (all 3 sides different values).
15% each yer
represented by
f(x)=60(1.15^x)
xintercept is when the function equals zero
since it increases only, it cannot equal zero and does not have an x intercept
after 4 years the investment value is 104
after 6 yaers value is 138.7
after 7.86 years the value is179.98 which is roughly 3 times of 60
8 years later183.54 close enough
answers
f(x)=60*1.15^x
after 7.86 years value is 3 times initioal value
after 8 years value is 184
A.
8z+3 > 3z-17
subtract 3 from both sides
8z > 3z -20
subtract 3z from both sides
5z > -20
divide both sides by 5
z > -4
