10^-3 means move decimal place 3 places to left or divide by 1000
move decimal place 3 places left
0.0030205 is normal form
It's the same because you're trying to find net price (end price)
You're going to take in both scenarios 100%-15%= 85%
You're always going to be paying only 85% of the price.
Answer:
Can you please provide a problem
The value of x is the final solution you get in your problem
Step-by-step explanation:
For example
10x = 50
X = 50/10
X = 5
The value of x is 5
The equation that represent the value of Alizeh’s investment after 20 years is y = 1000(b)^20
<h3>Exponential equation</h3>
The increase in the amount of his money can be represented using the exponential function as shown:
y = ab^x
Given the following
a = 1000
x = 20 years
Substitute
y = 1000(b)^20
Hence the equation that represent the value of Alizeh’s investment after 20 years is y = 1000(b)^20

The definite integral from x=2 to x=k of (6x-5) is
x^2
6*------- - 5x, [2,k] or 3[ k^2 -5k] - 3 [ 2^2 - 5(2) ]
2 or
3[k^2 - 5k] - 3[4-10] = 10 (as given)
3k^2 -15k + 18 = 10, or
3k^2 - 15k + 8 = 0
This is a quadratic equation; solve it using the quadratic formula:
-(-15) plus or minus sqrt( [-15]^2 - 4(3)(8) )
k = ------------------------------------------------------------
6
15 plus or minus 26.36
= ------------------------------------
6
