The Answer is 21 because 7 and 3 can go in it as well
Answer:

-- Her equivalent weight on earth
Step-by-step explanation:
Given
The attached table
Required
Fill in the gaps
(a) The equation
First, we calculate the slope (m)

From the table, we can say that:


So, we have:




The equation is then calculated using:

This gives:




(b) When x = 54
Substitute 54 for x in 


Answer:
y=-50*0.2^x
Step-by-step explanation:
the formula for an exponential function is:
y=a*b^x
what do we multiply -50 by to get -10?
-50x=-10
x=-10/-50
x=1/5
x=2/10
x=0.2
This initial value here is -50, it is the first in the table
y=-50*0.2^x
Answer:
25.85 years
Step-by-step explanation:
Use the formula for continuous compounding amount:
A = Pe^(r*t), where r is the interest rate as a decimal fraction, P is the initial amount, and t is the time in years.
Here we have:
A = $200e^(0.0425*t) = 3($200) (this is triple the original amount)
Solve this for t. Divide both sides by $200 and then use natural logs:
1e^(0.0425*t) = 3
Then 0.0425*t = ln 3 = 1.0986
Dividing both sides by 0.0425 will isolate t:
1.0986
t = --------------- = 25.85 years
0.0425
Hi there!

1/3x = 6
Begin by multiplying both sides by 3 to cancel the fraction:
1/x = 18
Take the reciprocal of both sides:
x = 1/18
