Answer:
B
Step-by-step explanation:
The data of the poulation increased.
Y=ab^x
logab=x
log7(1/343)=-3
y=7(1/343)^-3
B is the y-intercept. in this example, b=50
The way to get the equation for the radius (r) is to get r by itself. So divide each side by 4pi
500/4pi=r^2
Now take the square root of each side to get the equation of r.
sqrt(500/4pi)=r
Answer:
x = 30
Step-by-step explanation:
by solving ;
- 18 / x = 6 / 10
- 1 / x = 6 / ( 18 × 10 )
- 1 / x = 6 / 180
- 1 / x = 1 / 30
- x = 30
