Answer:

[tex]1) - 2n + 14[/tex]

[tex]2)- 5n + 30[/tex]

Step-by-step explanation:

[tex]n = a + (n - 1) \times d \\ = 12 + (n - 1) \times - 2 \\ = 12 - 2n + 2 \\ = - 2n + 14[/tex]

[tex]n = a + (n - 1) \times d \\ = 25 + (n - 1) \times - 5 \\ = 25 - 5n + 5 \\ = - 5n + 30[/tex]

The product of two complex numbers is SOMETIMES a complex number.

this is because you can add 2 complex numbers and get a whole number, which is not a complex number. However, you can add 2 complex numbers and sometimes get another complex number.

Answer:

The expression that belongs in the box is 8 x 4

Option C is correct answer.

Step-by-step explanation:

We need to find Which expression belongs in the box?

[tex](3 \times 8) \times 4= 3 \times (------)[/tex]

The property applied here is associative property of multiplication.

Associative property of multiplication states that:

[tex](a \times b)\times c = a \times (b \times c)[/tex]

So, if we apply the property to our question we have:

a = 3

b = 8

c = 4

So, the expression will become: [tex](3 \times 8) \times 4= 3 \times (8 \times 4)[/tex]

So, the expression that belongs in the box is 8 x 4

Option C is correct answer.

Answer:

8 hours

Step-by-step explanation:

A person came to work by 8:30 am

He went out to lunch 11:45 am and came back 12:30 pm

He closed 5:15 pm

Therefore the total hours worked that day can be calculated as follows

Time worked from 8:30 am to 11:45 am is 3 hours 15 mins

Time worked for 12:30 pm to 5:15 pm is 4 hours 45 mins

3 hours 15 mins + 4 hours 45 mins

= 8 hours

Hence the total hours worked that day is 8 hours

Answer:

  a factor of 2 is shown, but 4 was factored out

Step-by-step explanation:

The difference of squares is factored as ...

  a² -b² = (a +b)(a -b)

Then the given difference of squares factors as ...

  144x² -100 = (12x)² -10² = (12x +10)(12x -10)

Each of these factors has a factor of 2 that can be factored out:

  = (2(6x +5))(2(6x -5))

  = (2·2)(6x +5)(6x -5)

  = 4(6x +5)(6x -5)

The first factor should be 4, not 2.

Answer:

The temperature at 1,000 feet will be 56.4ºF; at 2,000 feet it will be 52.8ºF; and at 3,000 feet it will be 49.2ºF.

Step-by-step explanation:

Given that W. Altus is climbing 3,000 feet to the top of a mountain, starting at a temperature of 60ºF, which decreases 3.6ºF every 1,000 feet of elevation, to determine the temperature every 1,000 feet of elevation, the following calculations must be performed:

0 feet = 60ºF

1,000 feet = 60ºF - 3.6ºF = 56.4ºF

2,000 feet = 56.4ºF - 3.6ºF = 52.8ºF

3,000 feet = 52.8ºF - 3.6ºF = 49.2ºF

Thus, the temperature at 1,000 feet will be 56.4ºF; at 2,000 feet it will be 52.8ºF; and at 3,000 feet it will be 49.2ºF.

Answer:

Because they find it hard to pass in the past.

Step-by-step explanation:

Non-STEM majors detest taking algebraic courses at the collegiate level because based on their past experiences in high school, whereby they probably do not excel in algebra, numbers, or mathematical subjects in general, the thought of going through advanced numbers and equations can be overwhelming.

Nobody wants to have or at least start college with poor grades. Hence, because non-STEM students find algebraic courses hard to pass in the past, they detest taking the course that has to do with it at the college level.

Answer:

The directional derivate is given by: [tex]D_{u}(x,y) = \frac{6}{\ln{17}\sqrt{10}}[/tex]

Step-by-step explanation:

The directional derivative at point (x,y) is given by:

[tex]D_{u}(x,y) = f_{x}(x,y)*a + f_{y}(x,y)*b[/tex]

In which a is the x component of the unit vector and b is the y component of the unit vector.

Vector:

We are given the following vector: [tex]v = (3,1)[/tex]

Its modulus is given by: [tex]\sqrt{3^2 + 1^2} = \sqrt{10}[/tex]

The unit vector is given by each component divided by it's modulus. So

[tex]v_u = (\frac{3}{\sqrt{10}}, \frac{1}{\sqrt{10}})[/tex]

This means that [tex]a = \frac{3}{\sqrt{10}}, b = \frac{1}{\sqrt{10}}[/tex]

Partial derivatives:

[tex]f(x,y) = \ln{(2 + 3x^2 + 3y^2)}[/tex]

So

[tex]f_x(x,y) = \frac{6x}{\ln{(2 + 3x^2 + 3y^2)}}[/tex]

[tex]f_x(1,-2) = \frac{6(1)}{\ln{(2 + 3(1)^2 + 3(-2)^2)}} = \frac{6}{\ln{17}}[/tex]

[tex]f_y(x,y) = \frac{6y}{\ln{(2 + 3x^2 + 3y^2)}}[/tex]

[tex]f_y(1,-2) = \frac{6(-2)}{\ln{(2 + 3(1)^2 + 3(-2)^2)}} = -\frac{12}{\ln{17}}[/tex]

Directional derivative:

[tex]D_{u}(x,y) = f_{x}(x,y)*a + f_{y}(x,y)*b[/tex]

[tex]D_{u}(x,y) = \frac{6}{\ln{17}}\times\frac{3}{\sqrt{10}}-\frac{12}{\ln{17}}\times\frac{1}{\sqrt{10}}[/tex]

[tex]D_{u}(x,y) = \frac{18}{\ln{17}\sqrt{10}} - \frac{12}{\ln{17}\sqrt{10}}[tex]

[tex]D_{u}(x,y) = \frac{6}{\ln{17}\sqrt{10}}[/tex]

The directional derivate is given by: [tex]D_{u}(x,y) = \frac{6}{\ln{17}\sqrt{10}}[/tex]

Answer:

We should reject H₀   for values of | x₁| > 5,26     |x₁| > 6,12

Step-by-step explanation:

Sample mean    μ₀  =  5,7

Sample size       n₁  = 24

Sample standard deviation   s =  1

Significance level    α  = 0,05        CI = 95 %

Hypothesis criteria: Valves don´t meet the specification, which means pressure could be higher or lower than nominal

Normal Distribution where n < 30 we should use a two-tail t-student test

degree of freedom     df =  24 - 1  = 23

And with df = 23  and  α = 0,025 we find in t-tables the value for

t(c) =  - 2,0687     ( on the left tail )

Test Hypothesis:

Null Hypothesis                                       H₀            x  = μ₀

Alternative Hypothesis                           Hₐ            x  ≠ μ₀

To compute  t(s)

t(s) = ( x  -  μ₀ ) / s/√n

t(s) = ( x - 5,7 )*4,80

t(s) =  4,80*x  -  27,34

Then   for values of  t(s)   |t(s)| > 2,0687 we have to reject H₀

If we make   t(s)  =  t(c)  we find

-2,0687 = 4,8*x - 27,34

x  = ( 27,34 - 2,07 ) / 4,8      and on the other tail  x  = 6,12

x = 5,26

Therefore for values of 5,26 ( under )   and above 6,12 we shoud reject the Null hypothesis
