Answer:
1. is b and 2. is c
Step-by-step explanation:
Answer:
15 meters
Step-by-step explanation:
................
First you would simplify the left side to get,
ln( ( 3x+1 ) / ( 5+x ) ) = ln 2
Then raise both sides as the power of e, so it would basically cancel out the ln's.
3x+1 / 5+x = 2
3x+1 = 2( 5+x )
3x+1 = 10+2x
x = 9
Answer:
Step-by-step explanation:
strategy: find the distance of the two points, take half of that, b/c that will be the radius, Then use the area of a circle formula to find the answer
P1 = (1,-1) in the form (x1,y1)
P2= ((3,3) in the form (x2,y2)
dist = sqrt [ (x2-x1)^2 + (y2-y1)^2 ]
dist = sqrt [ 3 -1 )^2 + 3-(-1)^2 ]
dist = sqrt [ 2^2 + 4^2 ]
dist = sqrt [ 4 + 16 ]
dist = sqrt [20]
r = /2
area of circle =
area of circle = ( /2)^2
area of circle = ( /2)( /2)
area of circle = (20 / 4)
area of circle = 5
area of circle = 5
2 .64
that 2 is ur whole number, it stays ur whole number
.64....the last digit (4) is in the hundredths place, so put it over 100
2 64/100 reduces to 2 16/25 <==
