Answer:
<u><em>k = 0.2645</em></u>
Step-by-step explanation:
Given model:
y = 4070 
y = no. of hits website received = 9000 (in 3rd month)
t= no. of months website has been operational = 3
put in the above equation:
9000 = 4070 
=
=
<u><em>Taking natural logarithm on both sides, we get:</em></u>
=
= 3k ln<em>e</em>
ln<em>e</em>=1
= 3k
or k = 
k =(0.7936)
<em>k = 0.2645</em>

I think x=24 but not sure
Answer:
The total allowance is $18.5, and the amount spent daily is $3.2
Step-by-step explanation:
let T and x represent the total allowance and the amount spent daily respectively.
It was started that the amount remaining after 2 days is $12.10 , which implies the person has spend an equal amount for 2 days
T - 2x =12.10 (equation 1)
It was started that the amount remaining after 5 days is $2.50 , which also implies the person has spend an equal amount for 5 days
T - 5x =2.5 (equation 2)
subtract equation 2 from 1
T - 2x -( T - 5x ) = 12.10 -2.5
T - 2x -T + 5x = 9.6
3x =9.6
Divide both side by 3
x = 9.6/3 =3.2
from equation 1
T - 2x =12.10
T = 12.10 + 2x = 12.10 + 2*3.2
= 12.10 + 6.4 = 18.5
I’m not sure if it’s correct but I think you have to find the slope in order to get your answer
Answer:
Step-by-step explanation:
Since we are given the central angle in radians, we should use the following formula for the arc length.
Where <em>s</em> is the arc length, θ is the angle in radians, and <em>r</em> is the radius.
We know this circle has a radius of 9 inches and the central angle is 3.25 radians.
Substitute the values into the formula
Multiply.
The arc length is <u>29.25 inches. </u>
