MAY i ASK where is the picture my good kind sir?
Answer:
54.7%
Step-by-step explanation:
Given the function :
y=2700(0.453)
y represents an exponential Decay function because :
For a growth function ; the function :
y = A(1 + r) where, A is the initial amount and r = growth rate
With this function ; the value in bracket will always be greater Than 1
Hence, when the value after the initial value is less than 1 ; then we have an exponential Decay ;
Where
y = A(1 - r)
Hence, rate, r equals :
1 - r = 0.453
1 - 0.453 = r
r = 0.547
= 0.547 * 100%
= 54.7%
4x^2 = 100
x^2 = 25
x = + or - 5
x = 5 or x = -5
Hope this helps.
Answer:
x1 = 275 miles (shorter)
x2 = 318 miles (longer)
Step-by-step explanation:
Let
x1 = be the shorter route
v1 = speed of the car in the shorter route
t1 = time it took to cover shorter route
x2 = the longer route
v2 = speed of the car in the longer route
t2 = time it took to cover longer route
x1 + 43 = x2 (1)
v2 = v1 -2 (2)
v2 = x2/t2 = x2/6
v1 = x1/t1 = x1/5
This means that
v2 = v1 -2 =>
x2/6 = x1/5 -2
The system of equations results
a. x1 -x2 = -43
b. x1/5 - x2/6 = 2
Solving this system of equations, we find that
x1 = 275 miles
x2 = 318 miles
First you have to find 1/3 of the marbles. That means in the twelve marvels she has, there are three even groups. Divide twelve by three and you get four. So if each group is four, it is simple from here on out. If she started out with twelve and she lost 1/3 of them(4) it would be 12-4. You know this because lost is another for for subtract. 12-4=8. She has 8 marbles left.
