Answer:
(3) the function is decreasing for all real numbers of x where x< 1.5
Step-by-step explanation:
The function given in this problem is
which can be rewritten as:
A function is:
- Increasing over a certain interval if the first derivative is positive in that interval
- Decreasing over a certain interval is the first derivative is negative in that interval
So we start by calculating the first derivative of this function. We get:
This function is positive when:
Which means, when x > 1.5.
So the function is:
- Increasing for x > 1.5
- Decreasing for x < 1.5
So the correct option is
(3) the function is decreasing for all real numbers of x where x< 1.5
The interest Ernesto will earn in 1 year to the nearest cent is 2200 cents.
<u>Given the following data:</u>
To calculate how much interest Ernesto will earn in 1 year to the nearest cent:
<h3>How to calculate
compound interest.</h3>
Mathematically, compound interest is given by this formula:
<u>Where:</u>
- P is the principal or starting amount.
- T is the time measured in years.
Substituting the given parameters into the formula, we have;
B = $22.
<u>To cents:</u>
B =
B = 2200 cents.

Answer:
The Answer Is 125.
Step-by-step explanation:
As, 18 More Than K Means
18 More Than 7
So, It's 25
Then Evaluate 25 With 5
It's 25(5)
Or 25 × 5
It's 125.
Since x is less than 0 we have to use -2x.
Substitute -3 for x.
f(x) = -2(-3)
f(x) = 6
Answer = 700000
