3D geometry is the study of shapes in 3D space using three coordinates: x-coordinate, y-coordinate, and z-coordinate. To discover the exact location of a point in 3D space, three criteria are required.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Answer:

2 is in the hundredths place

25 : 1,25,50,75,100,125,150,175,200

40: 1,40,80,120,160,200

They will meet again after 200 minutes.

[tex]x = \frac{200}{60} = 3 + \frac{20}{60} [/tex]

So they will meet again after 3 hours and 20 minutes;

9:30 + 3:20 = 12:50 p.m.

That's your answer

The next time where both bus A and bus B are together at a stop is

12:50 pm.

Given,

Bus A stops at a certain bus stop every 25 minutes.

Bus B stops at the same stop every 40 minutes.

If both buses are at the bus stop at 9:30 a.m.

We need to find when is the next time they will be there together again.

1 hour = 60 minutes.

Find the total minutes traveled by bus A after 8 stops.
We have,

1 stop = 25 minutes

Multiplying by 8 on both sides.

8 x 1 stop = 8 x 25 minutes

8 stops = 200 minutes

We see that at the 8th stop bus A has traveled for 200 minutes.

Find the total minutes traveled by bus B after 5 stops.
We have,

1 stop = 40 minutes

Multiplying both sides by 5.

5 x 1 stop = 5 x 40 minutes

5 stops = 200 minutes

We see that at the 5th stop bus B has traveled for 200 minutes.

We can say that after 200 minutes of traveling each bus has stopped at the same place.

We have,

Both buses are at the bus stop at 9:30 a.m.

So,

60 minutes = 1 hour

200 minutes

= 60 minutes + 60 minutes  + 60 minutes  + 20 minutes

= 3 hours 20 minutes

So,

9:30 am + 3 hours 20 minutes

= 12:50 pm

Thus the next time both the buses are together is 12:50 pm.

Answer: 40,320

Step-by-step explanation:

By Permutation,

The number of arrangements for n things is given by n!.

[Here order matters]

Given: Number of people will give a presentation in class  =8

Then, the number of different orders = 8!

= 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

= 40320

Hence,  the number of different orders = 40,320

Answer: 4th box

Step-by-step explanation:

Answer:

y = x/2 means that it's whatever x is and that divided by 2

Step-by-step explanation:

For example for 8 it would be y=8/2 which is 4

14 would be 7

3 would be y= 3 x 2 your multiplying because the value is y so it's 6

Answers (from top to bottom)

Reasoning:

The rule says if you know what x is, divide by 2 to get y

In the first row, if x = 8, then y = x/2 = 8/2 = 4.

In the second row, x = 14 leads to y = 7 since 14/2 = 7.

The third row has us go in reverse. We multiply the y value by 2 to find x

This is because y = x/2 solves to x = 2y. So if y = 3, then x = 2y = 2*3 = 6.

We can then check this to get y = x/2 = 6/2 = 3.

Answer:

y = (x - 5)^2 - 6

Step-by-step explanation:

If you slide a parabola up or down, that translation will show up in the equation just tacked on to the end of the equation. Down 6 will be a MINUS 6.

A horizontal shift will show up in the equation tucked in close to the x in a set of parenthesis. BUT it will look less intuitive...a right shift will be a MINUS.

Untransformed:

y = x^2

Shift down 6:

y = x^2 - 6

Shift right 5:

y = (x - 5)^2

Down6 AND Right5:

y = (x - 5)^2 - 6

While making a perfect square for the given quadratic equation [tex]\rm x^2+3x+c=\frac{7}{4} +c[/tex] the value of c is 9/4

It is given that the quadratic equation  [tex]\rm x^2+3x+c=\frac{7}{4} +c[/tex] while forming the perfect square.

It is required to find the value of c.

It is defined as the equation of polynomial of degree two. The standard form of the quadratic equation is as follows:

[tex]\rm ax^2+bx+c=0[/tex]  where [tex]\rm a\neq 0[/tex]

We have a quadratic equation:

[tex]\rm x^2+3x+c=\frac{7}{4} +c[/tex]

We know that we can make any quadratic equation into a perfect square by the perfect square trinomial method as follow:

[tex]\rm ax^2+bx+c=0\\\rm ax^2+bx=-c\\\rm ax^2+bx+(\frac{b}{2a})^2 =-c+(\frac{b}{2a})^2\\[/tex]

So, the value of 'c' would be:

[tex]\rm c=(\frac{b}{2a})^2\\[/tex]  here b=3 and a=1 by comparing the equation to the standard equation.

[tex]c=(\frac{3}{2\times1} )^2\\c=(\frac{3}{2} )^2\\c=\frac{9}{4}[/tex]

Thus,  while making a perfect square for the given equation the value of c is 9/4

Answer:

0.32km

Step-by-step explanation:

The speed that a tsunami can travel is modeled by the equation s = 356 StartRoot d EndRoot , where S is the speed in kilometers per hour and d is the average depth of the water in kilometers.

This is written mathematically as:

S = 356√d

What is the approximate depth of water for a tsunami traveling at 200 kilometers per hour?

S = 200km/hr

Hence:

200km/hr = 356√d

Divide both sides by 356

200/356 = 356√d/356

√d = 200/356

Square both sides

(√d)² = (200/356)²

d =(0.5617977528)²

d = 0.3156167151km

Approximately = 0.32km

Subtracting a negative is like adding

Answer:

y = 14

Step-by-step explanation:

Answer:

-1.4

Step-by-step explanation:

substitute 10 and -3y

so it should look like -3y=10-5.8

then simplify so its -3y=4.2

divide both sides by -3 and you get y = 4.2/-3

multiply both the numerator and denominator by 10 and you get                  y= 42/-30

reduce the fraction to lowest terms by extracting and canceling out 6.

you end up with - 7/5 which simplifies to -1.4 so y = -1.4
