[tex](-\infty,-4)\cup(8,\infty)[/tex]

Step-by-step explanation:

All real numbers on its own in interval notation is [tex](-\infty,\infty)[/tex], but if we are to exclude -4 and 8, then we would need two separate intervals joined in union.

Thus, [tex](-\infty,-4)\cup(8,\infty)[/tex] would be the correct notation

Answer: 9n - 2

Answer:

9n-2

Step-by-step explanation:

Using the critical point concept, it is found that f(x) has a horizontal tangent at x = 2 and at x = 7.

The critical points of a function are the values of x for which:

[tex]f^{\prime}(x) = 0[/tex]

At these points, the behavior of the function changes from increasing to decreasing or vice-versa, and the tangent is horizontal.

Looking at the graph given in this problem, we see that the behavior changes from increasing to decreasing at x = 2, and from decreasing to increasing at x = 7, hence these are the values of x for which the tangent is horizontal.

Answer:

The first factor of the mass of an average grain of rock salt 120 is 40 times the first factor of the mass of an average grain of table salt 3.

Step-by-step explanation: Answer from edmentum Hope it helped!

Answer:

From part D, the mass of an average grain of rock salt is 120 x 10^-4. The first factor is 120.

The mass of an average grain of table salt is 3 x 10^-4. The first factor is 3. Let x times the first factor of the mass of an average grain of table salt be equal to the first factor of the mass of an average grain of rock salt.

3x = 120

x = 120/3

x = 40

So, the first factor of the mass of an average grain of rock salt (120) is 40 times the first factor of the mass of an average grain of table salt (3).

57.4 millilitres

We know that the chemist has 332 milliliters of the solution of acid and water, and 17.3% of that solution is acid.

We can then persume that the amount of acid in the solution is equal to 332ml × 17.3%

This is equal to 57.436ml.

Then the question states to round the answer to the nearest tenth.

Rounding 57.436ml to the nearest tenth (.1) will equal to 57.4ml.

Therefore, there are 57.4ml of acid in the solution rounded to the nearest tenth.

Answer:

if you are asking us then probably a... hmmm -_- 3 yes
3 out of 10

Step-by-step explanation:

Answer: we’ll first to find how “smart” you are, we have to verify the level of unsmartness and see if there is any given number. Since the is no given number we will use x as our unknown number. Then we will subtract 1 from 10, therefore giving us the number 9 that we will use in our equation to determine the level of “smart”.

Now we will put 9 and x together:

9x

Now we will find the next part of our equation which will find by looking at how we got the number 9, which is: 10-1

Now we group the parts of this equation which will be:

9x÷10-1

First we will solve one side of our equation

10-1=9

Then we will insert the solved side of the equation

9x÷9

Now we will divide

9/9x
we are left with 1

x=1

Now we insert our solved number back into our previous equation with 1 replacing x

9⋅1÷10-1

Now after we have solved the equation

The answer is: -0.1 will be your level of “smart”

Answer:

Hunter and Maggie can both be correct because when the average rate of change is zero, the sum of all possible positive slopes and negative slopes on the interval will be zero. The sum of the possible positive slopes cancels out the sum of the possible negative slopes.

In this case the graph would be a parabola with the equation ax^2+bx+c where a is negative

According to hunter

In the interval [-2,2]

According to Maggie

They can be correct

Because

If sum of all positive and negative slopes is zero then average rate of change is zeRos

So there is only one possibility

Then they both are correct

The sum of the lemonade sold, the lemonade given to her cousins and

the amount left, gives the the amount of lemonade at the start.

Response:

Given:

The amount of lemonade Tiana sold at the sale = [tex]\dfrac{3}{4}[/tex]

The amount of lemonade Tiana gave to her cousins = [tex]\mathbf{\dfrac{3}{2}}[/tex] gallons

The amount of lemonade Tiana had left = [tex]\dfrac{7}{8}[/tex] of a gallon

Required:

The amount of lemonade, Tiana started with

Solution:

Let x represent the amount of lemonade Tiana started with, we have;

[tex]x = \mathbf{\dfrac{3}{4} \cdot x + \dfrac{3}{2} \ gallons + \dfrac{7}{8} \ gallons}[/tex]

[tex]\mathbf{x - \dfrac{3}{4} \cdot x} = \dfrac{3}{2} \ gallons + \dfrac{7}{8} \ gallons[/tex]

[tex]\dfrac{1}{4} \cdot x = \dfrac{3}{2} \ gallons + \dfrac{7}{8} \ gallons = \dfrac{19}{8} \ gallons[/tex]

[tex]x = \dfrac{19}{8} \ gallons \times 4 = \mathbf{9.5 \ gallons}[/tex]

The surface area of the prism is the amount of space occupied by the box

The surface area of the box of chocolates is 47 square units

The height of the prism is given as:

Length (L) = 7 inches

The dimension of the base of the prism is given as:

Base (B) = 3 inches

Height (H) = 4 inches

Slant height (s) = 5 inches

The surface area of the prism is then calculated as:

[tex]Area =B * H + S * L[/tex]

So, we have:

Answer:

0.99c + 9.99

Step-by-step explanation:

We know one part of the expression is going to be $0.99c, since it's $0.99 per custom skin, and c is the number of custom skins were getting.

Then we must add on the 9.99 on top of that, since that is the one-time membership fee. This is what the equation looks like :

0.99c + 9.99

Hope this helps :)

Answer:

5. y = $0.99c + $9.99

Step-by-step explanation:

To find the cost, let us solve the equation for y:

Plug 5 as a replacement for c

y = 0.99(5) + 9.99

y = 0.99 × 5 + 9.99               multiply

y = 4.95 + 9.99                     add

y = 14.94

Therefore, the answer to number 6 is $14.94, which is the cost of 5 skins.

Answer:

the correct answer would be 33
