find the relative error of the number 8.6 if both of it's digits are correct​

Parameterize S by

[tex]\vec r(s, t) = (1-s)(1-t)\,\vec\imath + 6s(1-t)\,\vec\jmath + 6t\,\vec k[/tex]

with 0 ≤ s ≤ 1 and 0 ≤ t ≤ 1.

Take the normal vector to S to be

[tex]\vec n = \dfrac{\partial\vec r}{\partial s}\times\dfrac{\partial\vec r}{\partial t} = (36-36t)\,\vec\imath+(6-6t)\,\vec\jmath+(6-6t)\,\vec k[/tex]

with magnitude

[tex]\|\vec n\| = 6\sqrt{38}(1-t)[/tex]

Then the surface integral is

[tex]\displaystyle \iint_S xy\,\mathrm dS = 6\sqrt{38} \int_0^1\int_0^1 (1-t)\,\mathrm dt\,\mathrm ds = \boxed{3\sqrt{\frac{19}2}}[/tex]

Answer:

-7,3

Step-by-step explanation:

The point on y - axis has coordinates = (0, -4)

We have a point whose coordinates are -  P(-7, -4)

We have to find the point on the y-axis that is 7 units from the point.

The distance between two points -

[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]

According to the question, we have -

Coordinates of Point : P(-7, -4)

Since the other point is on y - axis, therefore its x - coordinate will be 0.

Let the point on y - axis have coordinates as - (0, k).

Using the formula discussed above -

7 = [tex]\sqrt {\left( {-7- 0} \right)^2 + \left( {-4 - k } \right)^2 }[/tex]

49 = [tex](-7)^{2}[/tex] + [tex](-4-k)^{2}[/tex]

[tex](-4-k)^{2}[/tex] = 0

[tex](k + 4)^{2}[/tex] = 0

Solve the quadratic equation, you will get -

k = -4

Hence, the point on y - axis has coordinates = (0, -4)

Explanation:

The stomach muscle helps digest food. The muscle isn't something a person can control at will. Instead, the body handles it automatically. This is why choice A is one of the answers.

The intestinal muscles work in a similar fashion to help pass nutrients into the blood stream and also pass waste out of the body. All of these processes are done automatically and you don't have to think about them. They just happen. Therefore, choice B is another answer.

Another example of an automatic or involuntary muscle doing its own thing is the heart muscle. It continuously pumps blood to help distribute nutrients and oxygen, and also dump waste byproducts (eg: carbon dioxide) out of the body. So choice C is the third and final answer.

An example of a muscle that's voluntary are the biceps. You can flex these muscles, and move them around at will. For example, when you pick up an item. So this allows us to rule out choice D.

I'm not sure why your teacher listed "brain". It has properties related to muscles such as the idea of practicing a topic to help retain it (similar to exercising to stay in shape); however, the brain itself isn't a muscle on a technical biological level.

Step-by-step explanation:

A relation with no repeated domain values is a function. Relations 1 and 3 are both functions. Relation 2 has the domain value 4 repeated, so is not a function.

Answer is C...Use calculator

Using function concepts, we have that:

The actual percentage of smokers in 2010 was of 23%, while the estimated was of 13%, thus, the model underestimated the percentage by 10%.

-----------------------------

The function is:

[tex]p + \frac{x}{2} = 33[/tex]

In which

The percentage can be written as a function of the number of years, that is:

[tex]p(x) = 33 - \frac{x}{2}[/tex]

-----------------------------

2010 is 2010 - 1970 = 40 years after 1970, thus, the estimate of the percentage in 2010 is:

[tex]p(40) = 33 - \frac{40}{2} = 33 - 20 = 13[/tex]

The actual percentage of smokers in 2010 was of 23%, while the estimated was of 13%, thus, the model underestimated the percentage by 10%.

Answer:

  D.  72sin(α)cos(α)

Step-by-step explanation:

Given two sides and the angle between, the area of a triangle can be found from the formula ...

  Area = (1/2)ab·sin(C)

Here, that translates to ...

  Area = (1/2)(12)(y)sin(α)

Using the trig relation ...

  Cos = Adjacent/Hypotenuse

we can find y:

  cos(α) = y/12

  y = 12·cos(α)

__

Substituting this into the area calculation above, we have ...

  Area = (1/2)(12)(12·cos(α))sin(α)

  Area = 72sin(α)cos(α)

Step-by-step explanation:

a. log_a 64 = log_a 4³ = 3 log_a 4

= 3 (1.585) = 4.755

b. log_a 1/16 = log_a 4`² = -2 log_a 4

= -2(1.585) = -3.17

c. log_a 36 = log_a 4×9 = log_a 4 + log_a 9

= 1.585 + log_a 9

Using translation concepts, it is found that:

a) For a translation 6 units horizontally, 6 is either added or subtracted to the x-coordinate of the ordered pairs.

b) For a translation 3 units vertically, 3 is either added or subtracted to the y-coordinate of the ordered pairs.

c) The coordinates of the vertices of the translated image will be given according to the following rule: (x,y) -> (x ± 6, y ± 3).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For a translation 6 units horizontally, we have that:

Hence 6 is either added or subtracted to the x-coordinate of the ordered pairs.

For a translation 3 units vertically, we have that:

Hence 3 is either added or subtracted to the y-coordinate of the ordered pairs.

The coordinates of the vertices of the translated image will be given according to the following rule: (x,y) -> (x ± 6, y ± 3).

Since the glass that holds 10.75 fluid ounces and Arpi drinks 4.5 glasses of water in one day, then the amount of water that Arpi drinks will be calculated thus:

= 10.75 ounces × 4.5 glasses

= 48.375 ounces

= 48.38 ounce to the nearest hundredths

Answer:

Step-by-step explanation:

Bonjour,

5+5+5 = 15

3+3+3 = 9

6+6+6 = 18

6+6 + (5+6+3) *3  = 12 +14*3= 12+ 42 =  54

Answer:

54

Step-by-step explanation:

The man represents 5, because three of him are fifteen (15 ÷ 3 = 5). The mask represents 3, because three of it are 9 (9 ÷ 3 = 3). The dümbbell represents 6, because three of it are eighteen (18 ÷ 3 = 6).

So, 2 dümbbells + (1 man + 1 mask + 1 dümbbell) × 1 mask

= 2(6) + (5 + 3 + 6) × 3

= 12 + 14 × 3

= 12 + 42

= 54

Answer:

$73.78

Step-by-step explanation:

$68 + (68*8.5%)

$68 + (68*0.085)

$68 + $5.78

$73.78

The total price of the sweater will be $73.78.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The percentage is just like the amount of that value but in between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given that,

Price of sweater = $68

Percentage tax on the price of sweater = 8.5%

Now,

8.5% of 68 will be

⇒ 8.5 × 68/100 = $5.78

So, the total price will be

⇒ 68 + 5.78 = $73.78

Hence "The total price of the sweater will be $73.78".

Answer:

I am almost positive that the answer is 64 miles in one hour.

Step-by-step explanation:

In an hour the truck driver will cover the distance of 64 miles.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. The speed is a scalar quantity and does not require direction to represent it.

Given that a truck driver drove 48 miles in 45 minutes. The distance covered by the truck in an hour will be calculated as below:-

45 minutes ⇒ 48 miles

1 minute ⇒ 48 / 45

60 minute ⇒ ( 48 x 60 ) / 45

1 hour ⇒ 64 miles

Therefore, in an hour the truck driver will cover the distance of 64 miles.
