Answer:
The author sold a total of 30240 books following this trend.
Step-by-step explanation:
<em>Let's find 5% of 14400 first;</em>
14400 * 5%
14400 * 5/100
144 * 5
720 (So now we know that they are decreasing by 720 each month; therefore thats the constant)
<em>=> aₙ = a₁ + r(n - 1)</em>
=> a₂₃ = 14400 + 720(23 - 1)
=> a₂₃ = 14400 + 720(22)
=> a₂₃ = 14400 + 15840
<u>=> a₂₃ = 30240</u>

Answer:
Part a: 4 minutes
Part b: lap
Part c: 84 minutes or 1 hr and 24 minutes
Step-by-step explanation:
<em><u>Part a:</u></em>
Ok so you got part a right, it's 4 minutes.
<em><u>Part b:</u></em>
you would do that will give you .
So it's a quarter of a lap per minute.
<em><u>Part c:</u></em>
For this one we know that it takes her 4 minutes just to complete one lap, and if they're doing 21 laps that means we'll multiply 21 and 4. That gives us 84 minutes, or 1 hr and 24 min.
The value of x such that f(x) = g(x) is x = 3
<h3>Quadratic equation</h3>
Given the following expressions as shown
f(x) = x^3-3x^2+2 and;
g(x) = x^2 -6x+11
Equate the expressions
x^3-3x^2+2 = x^2 -6x+11
Equate to zero
x^3-3x^2-x^2+2-11 = 0
x^3-3x^2-x^2 + 6x - 9 = 0
x^3-4x^2+6x-9 = 0
Factorize
On factorizing the value of x = 3
Hence the value of x such that f(x) = g(x) is x = 3

Yes. That number is 0. When you subtract 0, it does nothing.
