Pls help........
Zinaida [17]

Answer:

During the interval 0 < x < 2, height of the water balloon is increasing.

Step-by-step explanation:

Graph of the linear function represents the height f(x) of a balloon over the time 'x' seconds.

There are three intervals of the time in which height of the balloon has been given.

1). In the interval of 0 < x ≤ 2, height of the water balloon is increasing (Since slope of the line is positive or the line is slanting upwards).

2). In the interval 2 < x ≤ 3, height of the water balloon is constant (Since slope of the line is zero).

3). In the interval 3 < x ≤ 4, height of the water balloon is decreasing faster. (Since the given line is slanting downwards).

4). In the interval 4 < x < 6, height of the water balloon is decreasing (Since the given line in this interval is slanting downwards).

Therefore, during 0 < x < 2, height of the water balloon is increasing.

In a survey of 3000 people who owned a certain type of​ car, 2100 said they would buy that type of car again. What percent of th
Annette [7]

Answer:

<h2>70%</h2>

Step-by-step explanation:

Step one:

given data

we are told that the  number of people under the survey is 3000

and also that 2100 people would like to buy again, these 2100 people represent the number of people who are satisfied with the type of car.

Step two:

Therefore the percentage of this number related to the total people under the survey is given below

=2100/3000*100

=21//30*100

=7/10*100

=7*10

=70%

<u>Hence 70% of the people surveyed are satisfied with the type of car</u>

What’s the derivative of the function: A) f(x)= 1/x , in point 2. B) f(x)= 5x^2 , in point 3
bija089 [108]

Using the power rule, the derivatives are given as follows:

a) f^{\prime}(2) = -\frac{1}{4}.

b) f^{\prime}(3) = 30.

<h3>What is the power rule for a derivative?</h3>

Suppose we have a power function given by:

f(x) = x^n

The derivative of the function is given by:

f^{\prime}(x) = n \times x^{n-1}

Item a:

The function is:

f(x) = \frac{1}{x} = x^{-1}

Then the derivative is:

f^{\prime}(x) = -x^{-2} = -\frac{1}{x^2}

When x = 2, the derivative is:

f^{\prime}(2) = -\frac{1}{4}

Item b:

The function is:

f(x) = 5x^2

Then the derivative is:

f^{\prime}(x) = 10x

When x = 3, the derivative is:

f^{\prime}(3) = 30
