What is C’ T’ if there was a rotation ?

Answer: OPTION A.

Step-by-step explanation:

Given the equation [tex]\frac{c-1}{x}+d=cd[/tex], you need to solve for the variable "x":

Subtract "d" from both sides of the equation:

[tex]\frac{c-1}{x}+d-d=cd-d\\\\\frac{c-1}{x}=cd-d[/tex]

Multiply both sides of the equation by "x":

[tex](\frac{c-1}{x})x=x(cd-d)\\\\c-1=x(cd-d)[/tex]

Divide both sides of the equation by [tex](cd-d)[/tex]:

[tex]\frac{c-1}{cd-d}=\frac{x(cd-d)}{cd-d}\\\\\frac{c-1}{cd-d}=x[/tex]

Factor out "d" in the denominator and simplify. Therefore:

[tex]\frac{(c-1)}{d(c-1)}=x\\\\x=\frac{1}{d}[/tex]

The correct solution for the equation c-1/x+d=cd is x = -1/(cd - c - d). Unfortunately, none of the provided options, 1/d, d, or c/d match this solution.

To solve the equation c-1/x+d=cd, we first move the terms involving x to one side and the constant to the other side. So the equation becomes:

-1/x = cd - c - d.

We then take reciprocals on both sides (since we do not want x in the denominator) to get:

x = -1/ (cd - c - d). Thus, the solution of the given equation is x = -1/(cd - c - d).

Unfortunately, none of the options A) 1/d, B) d, or C) c/d match the obtained solution.

Step-by-step explanation:

[tex].\qquad y^2-25x^2=25\\\\\implies \dfrac{y^2}{25}-\dfrac{25x^2}{25}=\dfrac{25}{25}\\\\\\\implies \dfrac{y^2}{25}-\dfrac{x^2}{1}=1\\\\\\Center: (0, 0)\\Length\ of\ foci:25+1=c^2\implies \sqrt{26}=c\\Foci: (0,0\pm \sqrt{26})[/tex]

Step-by-step answer:

Given:

Distance = 2464 miles

downwind time = 14 hours

upwind time  = 16 hours

Solution:

downwind speed  = 2464 / 14 = 176 mph

upwind speed = 2464 / 16 = 154 mph

Average speed = still air speed

= (176+154)/2

= 330/2

= 165 mph

Time required

= 2464 / 165

= 14.933 hours

= 14 hours 56 minutes.

Final answer:

The plane's speed in still air is 165 mph, and the wind's speed is 11 mph.

Explanation:

To solve the problem of finding the plane's speed in still air, and the wind speed, we can set up two equations based on the given information. Let the plane's speed be 'p' and the wind's speed be 'w'.

With the wind, the effective speed of the plane is 'p + w', and it travels 2464 miles in 14 hours. So we can write the equation:

2464 miles = (p + w) × 14 hours

Into the wind, the effective speed of the plane is 'p - w', and it travels the same distance in 16 hours. The second equation is:

2464 miles = (p - w) × 16 hours

Dividing the distance by the time in each equation gives:

By solving these two equations simultaneously, we can find the plane's speed and the wind's speed.

First, calculate the speed with and against the wind:

Now, we can add these two equations to eliminate 'w' and solve for 'p':

2p = 330 mph

p = 165 mph

The plane's speed in still air is 165 mph. To find the wind's speed 'w', we subtract one equation from the other:

The wind's speed is 11 mph.

Answer:

(D) 30pi inches

Step-by-step explanation:

First, we use the given volume, the given height, and the formula of the volume of a cylinder to find the radius of the base. Then we use the radius of the base to find the circumference of the base.

[tex] volume = \pi r^2 h [/tex]

[tex] volume = 6750 \pi~in.^3 [/tex]

We set the formula equal to the volume and replace h with 30 in.

[tex] \pi r^2 h = 6750 \pi~in.^3 [/tex]

[tex] \pi r^2 \times 30 ~in. = 6750 \pi~in.^3 [/tex]

Divide both sides by 30pi in.

[tex] r^2 = 225 ~in.^2 [/tex]

Take the square root of each side.

[tex] \sqrt{r^2} = \sqrt{225 ~in.^2} [/tex]

[tex] r = 15~in. [/tex]

The radius of the base is 15 in.

Now we use the radius of the base and the formula of the circumference of a circle to find the answer.

[tex] circumference = 2 \pi r [/tex]

[tex] circumference = 2 \pi \times 15~in. [/tex]

[tex] circumference = 30 \pi ~in. [/tex]

Answer:

[tex]\large\boxed{y=\dfrac{1}{4}x+3}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept → (0, b)

From the graph we have the points (4, 4) and (0, 3) → b = 3.

We have the equation:

[tex]y=mx+3[/tex]

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Put the coordinates of the points:

[tex]m=\dfrac{3-4}{0-4}=\dfrac{-1}{-4}=\dfrac{1}{4}[/tex]

Finally we have:

[tex]y=\dfrac{1}{4}x+3[/tex]

Points P and Q are not the same due to their different positions in the division of the directed segment. Point P is closer to A while Point Q is closer to B.

Point P and Q are not the same point. In the directed segment from A to B, Point P divides the segment in a way that the ratio of AP to PB is 1:3, meaning Point P is closer to A. On the contrary, Point Q divides the segment from B to A in a way that the ratio of QB to QA is 1:3, implying that Point Q is closer to B. Therefore, P and Q have different positions on the segment.

https://brainly.com/question/30277001

#SPJ12

No, Point P and Q are not the same. P is closer to A because it partitions the directed segment from A to B, whereas Q is closer to B as it partitions the segment from B to A, taking into account the directionality of the segments.

In mathematics, partitioning points on a directed segment refers to dividing the segment into distinct parts according to a given ratio. Point P partitions the directed segment from A to B into a 1:3 ratio, which means P is one part from A and three parts from B. On the other hand, Point Q partitions the directed segment from B to A into a 1:3 ratio, indicating that Q is one part from B and three parts from A.

Given this, P and Q are not the same point. P is closer to point A and Q is closer to point B since the directionality of the segment is taken into account. The direction from A to B is not the same as the direction from B to A, so the points P and Q that partition these segments in a 1:3 ratio will end up at different locations.

Answer:

The elapsed time is 7hrs and 1 minute.

The elapsed time from 5 in the afternoon to 1 minute after midnight is 7 hours and 1 minute, taking into consideration the division of a day into a.m. and p.m.

The key to solving this question is first understanding how we measure time in day and night, which are demarcated by a.m. and p.m.. Each cycle of 24 hours is divided into two parts: 12 hours from midnight to noon (a.m.) and another 12 hours from noon to midnight (p.m.).

Let's calculate the elapsed time from 5 in the afternoon to 1 minute past midnight. From 5 p.m to midnight, there are 7 hours. Adding the 1 minute past midnight, the total elapsed time is 7 hours and 1 minute.

Answer:

V≈2.53×105^5

Step-by-step explanation:

Base edge:  54

Height:  260

Formula to find volume is: V=a^2h /3

Hope this helps!

For this case we have that by definition, the volume of a square base pyramid is given by:

[tex]V = \frac {1} {3} * L ^ 2 * h[/tex]

Where:

L: It's the side of the square base

h: It's the height of the pyramid

According to the data we have:

[tex]L = 54\m\\h = 260\m[/tex]

Substituting in the formula:

[tex]V = \frac {1} {3} * (54) ^ 2 * 260\\V = \frac {1} {3} * 2916 * 260\\V = \frac {1} {3} * (758160)\\V = 252,720 \ m ^ 3[/tex]

Thus, the volume of the building is [tex]252,720 \ m ^ 3[/tex]

[tex]\frac{\pi }{2}[/tex]

Step-by-step explanation:

In order to find the reference angle of a given angle, we have to determine its quadrant.

Since the angle given is:

[tex]\frac{3\pi }{2}[/tex]

The angle lies in third quadrant.

If the angle lies in the third quadrant, [tex]\pi[/tex] is subtracted from the given angle:

So,

[tex]Reference\ Agnle= \frac{3\pi }{2}-\pi\\= \frac{3\pi -2\pi }{2}\\=\frac{\pi }{2}[/tex]

So the reference angle for [tex]\frac{3\pi }{2}[/tex] is [tex]\frac{\pi }{2}[/tex] ..

Answer:

Step-by-step explanation:

First pull out  the common factor of ab

ab(8a^3 + (1/125)b^3)

This is basically the sum of cubes. The linear factor is

(2a + 1/5 b)

The other factor is these two factors squared and their multiplicand subtracted.

(2a^2 - 2/5 ab + 1/25b^2)

Now put  all this together and you get

ab(2a + 1/5 b)((2a^2 - 2/5 ab + 1/25b^2)

y - y1 = m(x - x1) is the general point slope form

y - 3 = 5(x - 4) plug in the given values

y - 3 = 5x - 20

y = 5x - 20 + 3

y = 5x - 17

The answer in slope intercept form is y = 5x-17

If you want to convert to standard form, then

y = 5x - 17

y+17 = 5x

17 = 5x - y

5x - y = 17 which is the answer in standard form (Ax + By = C)

Answer: [tex]x=-4[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Wow the wording of these questions keeps getting more like a version of clue than a school exam or test. Goodluck!

The largest number that should be added to -11 to obtain a sum less than -5 is 5.

To find the largest number that should be added to –11 to get a sum less than –5 you need to relate these two numbers. If you add a number to -11 that brings you exactly to -5, it means you're adding 6 (because -11 + 6 = -5). However, you need the sum to be less than -5. So the largest number you can add to -11 to get a number less than -5 would be 5 (because -11 + 5 = -6, and -6 is less than -5). So, the answer is 5.
