The last digit will simply be equal to 8^1000, since the 10 will not have any effect on the units digit. Take the first few powers of 8, examining only the last digit:
8^1=8
8^2=4
8^3=2
8^4=6
8^5=8
8^6=4
We see that it continues in this pattern. Powers evenly divisible by 4, therefore, end in 6. Since 1000 is divisible by 4, 8^1000 ends in 6, so 18^1000 also ends in 6.
Answer:
x>6.67
Step-by-step explanation:
3x+10>30
3x>30-10
3x>20
x>20/3
x>6.67
Answer:
5a-25=70
5a=70+25
a=95/5
a=19
Step-by-step explanation:
since a(b+c) = ab+ac
Y=tanx=sinx/cosx we cant divide by 0 so
cosx=0 would be a problm
cosx=0 when x=pi/2,3pi/2,...(2n+1)pi/2
(2n+1)pi/2=(2npi+pi)/2=2npi/2+pi/2=npi+pi/2
so its B
Answer:
14 meters
Step-by-step explanation:
The area of a circle can be found with the formula: πr^2
We can set up an equation to find the radius, and use that to find diameter.
πr^2=49π
Divide both sides by π.
r^2=49
r= 
r=7
Radius is half of diameter, which means 2r=d
d=2(7)
d=14
