If

m ≤ f(x) ≤ M

for

a ≤ x ≤ b,

where m is the absolute minimum and M is the absolute maximum of f on the interval [a, b], then

m(b − a) ≤

b


If

m ≤ f(x) ≤ M

for

a ≤ x ≤ b,

where m is the absolute minimum and M is the absolute maximum of f on the interval [a, b], then m(b − a) ≤ f(x) dx ≤ M(b − a).

f(x) dx ≤ M(b − a).

Use this property to estimate the value of the integral.

(10x − 20 sin(x)) dx

Answers

Answer 1

Use the fact that -1 ≤ sin(x) ≤ 1.

Then

20 ≥ -20 sin(x) ≥ -20 … … … (multiply each side by -20)

-20 ≤ -20 sin(x) ≤ 20 … … … (swap the endpoints)

10x - 20 ≤ 10x - 20 sin(x) ≤ 10x + 20 … … … (add 10x to each side)

and over the interval [7, 8], we have

7 ≤ x ≤ 8

70 ≤ 10x ≤ 80 … … … (multiply each side by 10)

so that the whole integrand is bounded by

70 - 20 ≤ 10x - 20 sin(x) ≤ 80 + 20

50 ≤ 10x - 20 sin(x) ≤ 100

Take m = 50 and M = 100. It follows that

[tex]50(8-7) \le \displaystyle \int_7^8 (10x-20\sin(x)) \, dx \le 100(8-7)[/tex]

which places the value of the integral between 50 and 100.

Since you’re solving, you can get rid of the denominator
6(x+5) = x - x + 4

Answers

Answer:

Domain: {-2,6,18}

Range: {-1,2,3}

This relation is not a function.

Step-by-step explanation:

The domain is all of the x values given listed in order from least to greatest and not repeating any numbers. The range is the same thing, but with the y values given. This is not a function because multiple ordered pairs have more than one output for the input. Let's take -2 in these ordered pairs. It has two different outputs, 3 and 2. Because of this, it is not a function.

How to subtract 32/10 and 7/5

Answers

The answer is 9/5
Explanation:
16/5 - 7/5
16 - 7/5

Basically, reduce the fraction of your equation, transform the expression & calculate.

Answer:

18/10 or 1 4/5

Step-by-step explanation:

32/10 - 7/5

Remember that in order to subtract fractions, you always need to have the same denominator.

The denominator of 32/10 is 10.

The denominator of 7/5 is 5.

Are the denominator the same? In other words, are 10 and 5 equal? No, so now we need to make the denominator the same so that they are equal. To do that, find the LCM of 10 and 5.

List the LCM:

10: 10, 20, 30

5: 5, 10, 15, 20

Do you see any numbers in the list of the two numbers that are the same? Yes, 10 and 20. But since we are finding the LCM (Least common multiple), we need to use the smallest common multiple, which is 10.

Now that we found the LCM, make the denominator of 7/5 the same as 32/10.

To do that, just multiply the numerator and the denominator of 7/5 by 2; 7 times 2 is 14, 5 times 2 is 10. The final fraction should be 14/10.

Do 14/10 and 32/10 have the same denominator now? Yes, right?

Now, it’s the simple part. We now have the expression, 32/10 - 14/10.

Just subtract across, but keep the 10 as the denominato. 32 - 14 is 18. Keep the denominator 10, and you get 18/10 as your answer.

Therefore, 18/10 or 1 4/5 (if turned into a mixed fraction and simplified) is the answer. Hope this helps!

A chemist is doing a new experiment to see if a new
medicine will kill the Corona virus. He starts the test with
10,000,000 virus cells, and after 12 hours there are 5,
000,000 virus cells. How many cells should he expect to be
left after one week? Create an equation.

Answers

Answer:

610 virus cells

Step-by-step explanation:

let 10,000,000 be y And 12hrs be z and the cells left at the end of the week be x

I.e

[tex]x = y { \binom {1} {2}} ^{ \binom{t}{tx} } [/tex]

where tx is how long it takes for 1/2 of it to decay and t is the number of hours it's supposed to decay

So

[tex]x \: = \: 10000000 \: \times {{\frac{1}{2}}} ^{ \frac{24 \times 7}{12} } [/tex]

t is 7 weeks × 24 to convert to hours

so, therefore, 24 × 7 ÷ 12 is 14 [tex]x = 10000000 \times \frac{1}{ {2}^{14} } [/tex]

so 10,000,000 ÷ 2^14

10,000,000 ÷ 16,348 = 610.4

therefore there are approximately 610 viruses left after one week

What is geometric transformation?

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have:

A square A shown in the picture is translated to square A'

As we can see in the picture.

The square A is translated as 1 unit left.

The transformation rule:

(x, y) → (x-1, y)

Thus, the transformation rule is (x, y) → (x-1, y) and the square A is translated as 1 unit left.

Contestants on a game show spin a wheel with 242424 equally-sized segments. Most of those segments show different prize amounts, but 222 of them are labeled "bankrupt":Suppose that a contestant is going to spin the wheel twice in a row, and the outcome of one spin doesn't affect the outcome of future spins. What is the probability that NEITHER of the spins land on "bankrupt"?

Answers

Using the principle of probability, the probability that the outcome of both spins does not land on "bankrupt" is 1/144

Given the Parameters :

Total Number of possible outcomes = 24 Number of outcomes labeled bankrupt = 2 Labels which aren't labeled bankrupt = 24 - 2 = 22

Recall :

P(A) = required outcome / Total possible outcomes

First spin :

P(not bankrupt) = 2 / 24 = 1/12

Second spin :

P(not bankrupt) = 2/24 = 1/12

P(neither lands on bankrupt) = 1/12 × 1/12 = 1/144

Therefore, the probability that neither lands on bankrupt is 1/144

The cost of admission to the Flemington Aquarium is $11.50 for each senior citizen, $14.75 for each adult, and $7.25 for each child. A family of 2 adults and 1 child plans to spend the day at the Flemington Aquarium. What if 2 more tickets for admission are purchased? If the additional tickets cost $14.50, determine what type of tickets the family purchases. Explain how you can determine the answer without calculating.

Answers

Answer:

Step-by-step explanation:

A) $51.5

B) two children tickets

Step-by-step explanation:

Given that the cost of admission for the Flemington Aquarium is $11.50 for each senior citizen, $14.75 for each adult and $7.25 for each child.

The cost of admission for the family of 3 adults and 1 child will be

(3 × 14.75) + (1 × 7.25)

44.25 + 7.25 = 51.5 dollars

What if two more tickets for admission are purchased for a total of $14.50?

Since there is no ticket of that amount, we can determine what type of tickets the family purchases by taking the amount of child tickets away from the amount. That is

14.5 - 7.25 = 7.25

The remaining money amount to child ticket again. We can therefore conclude that the two more tickets for admission purchased for a total of $14.50 are for 2 children tickets
