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%
Answer:
When Amina is 18. Saad would be;
k. 14
Step-by-step explanation:
Let "x" represent Anita's current age and let "y" represent Saad's current age, we have;
Anita's age = 2 × Saad's age
Therefore;
x = 2 × y...(1)
In 4 years, we will get;
x + 4 = 1.5 × (y + 4)...(2)
Substituting the value of x in equation (1) into equation (2), we get;
2·y + 4 = 1.5·y + 1.5 × 4 = 1.5·y + 6
2·y + 4 = 1.5·y + 6
2·y - 1.5·y = 6 - 4 = 2
0.5·y = 2
y = 2/0.5 = 4
Saad's current age = y = 4 years
From equation (1), we have;
x = 2 × y = 2 × 4 = 8
Amina's current age = x = 8 years
When Amina is 18, we have;
18 = 10 + 8 = 10 + x
Therefore, Amina would be 18 in 10 years time from now, from which we have;
Saad would be 10 years + y = 10 years + 4 years = 14 years in 10 years from now
Therefore, when Amina would be 18 years in 10 years from now Saad would be 14 years.

The answer to the above question can be determined as -
Let the point on the left side of P be Q, thus coordinates of Q are (a,1) and point on the right side of P be R, thus coordinates of R will be, (a+4, 1).
Now, it given that, between x coordinates of Q and R is 4, and it can be seen that they are getting divided into half.
So, the x coordinate of P will be - a + 
i.e. a + 2
<u>Thus, the x coordinate of P will be a +2.</u>
