f(x) = x^3- 9x

What is the average rate of change of f over the interval [1, 6]

**Answer:**

**Step-by-step explanation:**

[tex]\frac{f(b)-f(a)}{b-a}[/tex] This is the formula for the average rate of change

over the interval (a, b)

a and b are x values

f(a) ad f(b) think of them as y values

Start calculating f(a) and f(b) **a=1 b=6**

replace all x's in formula with a, (1)

f(1)=1³-9(1) = 1-9= -8 f(1) = -8

Now do : b (6)

f(6) = 6³ - 9 (6) = 216-54=162 f(6) = 162

now plug everything into your equation

[tex]\frac{f(6)-f(1)}{6-1} =\frac{162- (-8)}{5} =\frac{170}{5} =34[/tex] average rate of change.

notice the 162 - (-8) In math there is no subtraction, and you would change it to + and when you do that you much change the sign of the next value making -8 a +8.

Hope this helps. Good luck!

**Answer:**

x = -0.25+√2.4375i or -0.25-√2.4375i

**Step-by-step explanation:**

The quadratic formula works for this. The quadratic equation ...

ax² +bx +c = 0

has solutions given by the quadratic formula:

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Your equation ...

2x² +x +5 = 0

has coefficients a=2, b=1, c=5, so the quadratic formula tells you the solutions are ...

[tex]x=\dfrac{-1\pm\sqrt{1^2-4\cdot2\cdot5}}{2\cdot2}=\dfrac{-1\pm\sqrt{-39}}{4}\\\\x=\left\{-\dfrac{1}{4}+\dfrac{\sqrt{39}}{4}i, -\dfrac{1}{4}-\dfrac{\sqrt{39}}{4}i\right\}[/tex]

The decimal equivalents are ...

x = -0.25+√2.4375i or -0.25-√2.4375i . . . . . . the 'i' is outside the radical

If a histogram of a sample of men's ages is skewed, what do you expect to see in the normal quantile plot?

Answer: Points are not following a straight-line pattern

Step-by-step explanation:

**Histograms **are used to show the distribution of a dataset.

If the **histogram **is **skewed**, then it means that the **points **do not follow a **straight-line pattern**, on the **normal quantile plot**.

From the question, we understand that:

The **histogram **is skewed

This means that:

The **data points **of the **histogram **are either concentrated on the **right **or on the **left-hand side **of the **histogram**.

The above highlight mean that:

The **points **on the **histogram **are **unequal**.

Hence, you would see that the **points **do not follow a **straight line pattern **on the **normal quantile plot**.

**Answer:**

**Step-by-step explanation:**

uh what’s ur question?

find the value of x

The answer is 150.

I need to show my work.

THANKSSSS

**Answer:**

x = 150

**Step-by-step explanation:**

We know a circle is **360°**, so the angles must add up to 60°.

Step 1: Set up equation

x - 120 + x - 120 = 60

Step 2: Solve for *x*

Step 3: Check

*Plug in x to verify it is correct.*

150 - 120 = 30°

150 - 120 = 30°

30° + 30° = 60°

60° + 300° = 360°

Part B

What is the value of x?

**Answer:**

**Step-by-step explanation:**

just add up both alternate internal angles as they are both equal

so, the equation is: 2x-10 = 65-x

**Answer:**

The right equation will be 2x - 10 = 65 - x (you were wrong lol)

**Step-by-step explanation:**

We have: 2x - 10 = 65 - x

=> 2x - 10 + x = 65

=> 3x = 65 + 10 = 75

=> x = 75/3 = 25

A TV show has 26 episodes. Due to the lack of time, you can onlywatch 5 of them. However, in order to get a gist of what the showis about, you do not want to watch any two consecutive episodes.How many selections of 5 episodes are there with no two consecutiveepisodes chosen? Assuming that the order of selection is irrelevant.(Hint:this is a Stars and Bars problem)

**Answer:**

**Step-by-step explanation:**

Recall that: The number of combination to select any k consecutive element from n consecutive term is given by the equation [tex]^{n-k+1}C_k[/tex]

[tex]= \begin {pmatrix} ^{n-k+1}_{k} \end {pmatrix}[/tex]

where:

n = 26

k = 5

[tex]^{n-k+1}C_k= \begin {pmatrix} ^{26-5+1}_{5} \end {pmatrix}[/tex]

[tex]^{n-k+1}C_k= \begin {pmatrix} ^{22}_{5} \end {pmatrix}[/tex]

[tex]^{n-k+1}C_k= \dfrac{22!}{5!(22-5)!}[/tex]

[tex]^{n-k+1}C_k= \dfrac{22!}{5!(17)!}[/tex]

[tex]\mathbf{^{n-k+1}C_k=26334}[/tex]

Therefore, there are 26334 selection of 5 episodes with no two consecutive episodes chosen

1. You are eating on a Tootsie Roll Lollipop that is in the shape of a sphere. It is giving up volume at a steady rate of 0.25 in3 /min. How fast will the radius be decreasing when the Tootsie Roll Pop is .75 inches across?

**Answer:**

**Step-by-step explanation:**

Since the Tootsie Roll lollipop is a sphere

volume of sphere= [tex]\frac{4}{3}piR^3[/tex] = -0.25 [tex]in^3/min[/tex]

the negative sign indicates that the volume is decreasing

upon differentiating

as the diameter given is =0.75 so radius will be = 0.375

[tex]dV/dt = 4piR^2*dR/dt[/tex]

so [tex]dR/dt = 0.25/4*3.14 *(0.375)^2[/tex]

So the radius is decreasing at the rate of dR/dt= 0.142in/min

what is 4/6+2/3.?(these are fractions, you're just adding fractions)

**Answer:**

4/3

**Step-by-step explanation:**

Multiply 2 by 2, and get 4, then we multiply 3 by 2 and get 6.

Since our denominators match, we can add the numerators. 4 + 4 = 8. That gives us the sum, which is 8/6. Then you divide by 2. So 8/6 / 2 gives you 4/3.

**Answer:**

4/3 or 1 1/3

**Step-by-step explanation:**

1. 4/6 + 2/3

2. 4/6 + 4/6 **You have to find the LCM (least common multiple) of the two denominators. In this case it would be 6. You have to multiply 3 by 2 to get 6. What you do to the bottom you also do to the top so you have to also multiply the numerator (2) by 2.**

3. 4/3 or 1 1/3 ** Afterward, you just have to add straight across without changing the denominator and then if you need to simplify you simplify. Without simplifying, you would get 8/6, but, most teachers will mark it as wrong if you don't simplify. You can then change the improper fraction into a mixed number depending on what your teacher wants.**
