The temperature at 6000 meters would be -21.9°C.

The lapse Rate refers to the rate of decline in air temperature with relation to increase in altitude.

Here, the lapse Rate is given as follows-

for 0-1500 meters: 5.5 °C/1000m

for 1500-4000 meters: 12.1°C/1000m.

and above 4000 meters: normal lapse rate

The Normal lapse Rate is 6.5°C per 1000 meters.

Now,

surface temperature at sea level = 29.6°C

the decline in temperature up to 1500m would be-

5.5°C/1000×1500 = 8.25°C

So the temperature at 1500 meter is 29.6 - 8.25 = 21.35°C

Further, the decline in temperature up to 4000m would be-

12.1°C/1000×2500= 30.25°C

So Temperature at 4000 meters is 21.35 - 30.25 = -8.9°C

Now, above 4000 meters, decline in temperature would be-

6.5°C/1000×2000= 13°C

So temperature at 6000 meters would be

-8.9°C - 13°C = -21.9°C

Thus, the temperature at 6000 meters would be -21.9°C

Solution of the inequality is q> 1/4 and in interval notation is (1/4 , ∞ ).

According to the question we have been given the inequality that is

                3/4q - 2/3q < 5/12q - 1/12

Solving the equation step by step we get

First simplifying 3/4q - 2/3q which will get q/12

Therefore,         q/12 < 5/12q - 1/12

moving all the terms with q on the left hand side we get

                       q/12 - 5/12q < -1/12

                       (q-5q)/12 < -1/12

                          -4q/12 < -1/12

multiplying both sides by 12 we get

                            -4q/12 * 12 < -1/12*12

                                -4q < -1

multiplying -1 both sides we get

                                  4q>1

                                     q >1/4

Hence solution of the inequality we get

                  (1/4 , ∞ )

The equation of the parabola with the given focus and directrix is x² = 12( y - 4 ).

Since the directrix y = 1, it shows it is vertical, so we use the equation of the parabola that opens up or down.

( x - h )² = 4p( y - k )

Given the data in the question;

First, we determine the vertex.

The vertex ( h,k ) is half way between the directrix and the focus.

Find the y-coordinate of the vertex using;

y = ( y-coordinate of focus + directrix )/2

y =  (7+1)/2 = 8/2 = 4

The x-coordinate of the vertex is the same as that of the focus 0

Hence, the vertex is ( 0,4 )

Next, we determine the distance p from the focus to the vertex.

p = y-coordinate of focus - y-coordinate of vertex

p = 7 - 4

p = 3

Now, plug the known values into the equation and simplify

( x - h )² = 4p( y - k )

( x - 0 )² = 4(3)( y - 4 )

x² = 12( y - 4 )

Therefore, the equation of the parabola with the given focus and directrix is x² = 12( y - 4 ).

tan x = 1 / (cot x)

Tangent Formula Using Sin and Cos

We know that sin x = (opposite) / (hypotenuse), cos x = (adjacent) / (hypotenuse), and tan x = (opposite) / (adjacent). Now we will divide sin x by cos x.

(sin x) / (cos x) = [ (opposite) / (hypotenuse) ] / [ (adjacent) / (hypotenuse) ] = (opposite) / (adjacent) = tan x

Thus, the tangent formula in terms of sine and cosine is, 

tan x = (sin x) / (cos x)

by using inductive reasoning, we get the next 2 terms as 7 / 12 and 4 / 7.

We are given a sequence:

3 / 4, 2 / 3, 5 / 8, 3 / 5

We need to find the next two terms by using the inductive reasoning.

Now, we can also write this sequence as:

3 / 4, 4 / 6, 5 / 8, 6 / 10

Now, we can see that, in each term, the numerator is increasing by 1 and the denominator is increasing by 2 units.

So, the 5th term will be:

Numerator = 6+ 1 = 7

Denominator = 10 + 2 = 12

5th term = 7 / 12

And the 6th term will be:

Numerator = 7 + 1 = 8

Denominator = 12 + 2 = 14

6th term = 8 / 14 = 4 / 7

Therefore, by using inductive reasoning, we get the next 2 terms as 7 / 12 and 4 / 7.

Answer:

(-6, -8)

Step-by-step explanation:

We have the following system of equations:
[tex]y = 2x+4[/tex]    (1)

and

[tex]y=x-2[/tex]      (2)

Set (1) = (2) since the LHS is y in both

We get

[tex]2x + 4 = x - 2[/tex]

Subtract x from both sides:

[tex]2x + 4 - x = x - 2 -x[/tex]

[tex]x + 4 = -2[/tex]

Subtract 4 from both sides

[tex]x + 4 - 4 = -2 -4[/tex]

[tex]x = -6[/tex]

Substitute for x in Equation (2) to get
[tex]y = -6 - 2 = -8[/tex]

So the solution is (-6, -8)

Laine will take 30 minutes to read 25 pages.

Given Laine reads 200 pages in 240 minutes.

We need to find the time taken to read 25 pages, if Laine reads at the same rate.

First, let us find out the time taken to read one page.

240 minutes are taken to read 200 pages

This implies that the time taken to read 1 page = 240/200 minutes

This implies that the time taken to read 1 page = 6/5 minutes

Therefore, the time taken for 25 pages = 25 ×(6/5) minutes

⇒ The time taken for 25 pages = 30 minutes

Hence, Laine will read 25 pages in 30 minutes, if she reads 200 pages in 240 minutes.
