Did u make this up? Because there are would be loads
Answer:
yes it is bcz if you do 6^2+8^2 you get 10
Answer: t ≈ 20 years
Step-by-step explanation:
Since it is compounded continuously , we will use the compound interest formula:
A = P![e^{rt}](https://tex.z-dn.net/?f=e%5E%7Brt%7D)
Where A is the amount when tripled
P is the initial amount
r is the rate
t is the time
since the investment is tripled , it means the A = 3P.
From the question:
A = 3P
P = $6000
r = 5.5%
t = ?
Substituting into the formula , we have
3P = P
, that is
3(6000) = 6000![e^{0.055t}](https://tex.z-dn.net/?f=e%5E%7B0.055t%7D)
Dividing through by 6000 , we have
3 = ![e^{0.055t}](https://tex.z-dn.net/?f=e%5E%7B0.055t%7D)
Take the In of both sides in order to remove the exponential , that is
In 3 = 0.055t
divide through by 0.055
t = In 3 / 0.055
Therefore :
t = 19.97476888
t≈ 20 years
Part A: The correlation
coefficient is 1. It means that the values of both x and y has a strong
relationship giving them a avalue of 1.
Part B: The value of the slope
of the graph is 0.5. the slope of the line represents how steep is the line of
your graph
Part C: The data presented is
correlation.
Answer:
10 km per hour
Step-by-step explanation:
Just set up a proportion:
2,000 meters x meters
---------------------- = -----------------------
12 minutes 60 minutes
Cross multiply:
12x = 120000
x = 10000 meters per hour
In km, it would be hmm... *thinks* 10 km per hour :D
