Answer:

<em>Correct answer: C.  (1,∞)</em>

Step-by-step explanation:

<u>First Derivative</u>

Given a real continuous function f(x), the first derivative f'(x) represents the slope of the tangent line for any value of x.

If the slope of the line is positive, then the function is increasing, if the slope of the line is negative, the function is decreasing.

The function to analyze is:

f(x)=x^2-2x+1

Computing the first derivative:

f'(x)=2x-2

The function will be increasing when:

2x-2>0

Dividing by 2:

x-1>0

Solving:

x > 1

This solution is represented by the interval (1,∞)

Correct answer: C.  (1,∞)

A jar has 32 marbles. Some are blue and the rest are green. There are three times as many green marbles as blue. How many green
ella [17]

Answer: 24

Step-by-step explanation:

Number of marbles in jar = 32

Let blue marbles be represented by b.

Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b

We then add them together. This will be:

3b + b = 32

4b = 32

b = 32/4

b = 8

There are 8 blue marbles

Since green is 3× blue. Therefore,

Green = 8 × 3 = 24 marbles

Here’s what you can do to make this very simple. Consider that the “missing” space between the rectangles isn’t there. Then, find the area:

10 x 9 = 90 mm

Now, find the area of the “missing” part.

5 x 2 = 10 mm

Finally, you deduct the missing part from the complete rectangle!

90 - 10 = 80 mm

The area of this whole thing is 80 mm!
