Find AB given A(-4, 1) and B(3, -1).

Answer: The submarine would be 710 feet below the surface after it is finished diving.

Step-by-step explanation:

Given: Each move downward was of 355 feet

If the submarine dives below the surface, heading downward in two moves.

Then, the total distance moved by submarine = 2 (355) feet

= 710 feet

Therefore, the submarine would be 710 feet below the surface after it is finished diving.

Step-by-step explanation:

1. [tex]\sqrt{72}[/tex]  break it apart so you can solve

   [tex]\sqrt{2} *\sqrt{36}[/tex]

   [tex]\sqrt{2}[/tex] * 6

It's irrational. [tex]\sqrt{2}[/tex] can not be written as a ratio.

2.

         2.4222...    2/90 = .22222....     36/90 = .4    180/90 = 2

                            2+36+180 = 218/90 which is a ratio, so it's rational

   b.  [tex]\sqrt{8} = 2\sqrt{2}[/tex]  

          [tex]\pi[/tex]

3.

    6.51326.... and [tex]\sqrt{39}[/tex]

The [tex]\sqrt{39}[/tex] = 6.2445

Comparing to the 6.51326, it has a difference of 0.268262. Thus, 6.51326 is greater than square root of 39.

Answer:

The function is missing in the question. The function is [tex]$ C(x) = 0.8x^2 -544x +97410 $[/tex]

The answer is 4930

Step-by-step explanation:

Unit cost of a car is given as

[tex]$ C(x) = 0.8x^2 -544x +97410 $[/tex]

Cost will be minimum when

x = -(-544)/ 2 x 0.8

  = 340

Therefore, minimum cost for unit car is

[tex]$ C(x) = 0.8x^2 -544x +97410 $[/tex]

[tex]$ = 0.8(340)^2 -544(340) +97410 $[/tex]

=  4930

Answer:

6 and 7 sorry if im wrong

Step-by-step explanation:

The line that forms the hypotenuse includes line AB.

Gradient of line AB = Rise/Run = (5-2)/(0-4) = -3/4.

y = -3/4 * (x) + c

When x = 0, y = 5. Hence c is 5.

The equation is y = 5 - (3x/4).

Answer:

x = 4

Step-by-step explanation:

Given

3(4x - 7) = 27 ( divide both sides by 3 )

4x - 7 = 9 ( add 7 to both sides )

4x = 16 ( divide both sides by 4 )

x = 4

Answer:

x=4

Step-by-step explanation:

Distribute the 3 to the 4x and -7v

it will be 12x - 21= 27

you then take the 21 and add it to the 27 to isolate the 12x

it will be 12x = 48

to seperate the 12 from the x you divide on both sides so x/12 and 48/ 12

this will give you x= 4

Answer:   16,425   gallons are wasted a year

Step-by-step explanation:

First find out how many minutes there  are in a year then multiply it by how much oz the faucet leaks every years then convert it into gallons.

There are 525,600 minutes in a year now multiply it by 4.

525,600 * 4 = 2,102,400  So there are more than 2 million oz  wasted in a year so now convert it to gallons.

If there are 128 oz for every gallons the divide 2,102,400 by 128 to find out how many gallons are wasted a year.

2,102,400 / 128 = 16,425

Answer:

he has to start at 8:30 PM I think

Step-by-step explanation:

it's because you do 30*5 then you get the answer 150, then you will do 150/60 whitch will get you to 2.5 and I think 2.5 is 2 hours, and 30 minutes. Then you minius 2 hours, and 30 minutes to the 10 hours and you get 8:30 PM (I don't know if that's correct or not)

answer is BC=4

notice that the starting point is A and the endpoint is C, it stated that from A to B the value is 7 and from A to C the value is 11 we just need to subtract AC-AB to find the third value of it

AC-AB= 11-7 =4

Answer: 0.5, 3/4, 14/5

Step-by-step explanation:

The most likely next step in the series is Option B.

Option B is the correct answer.

A series of patterns is a sequence of related designs, shapes, colors, or other elements that follow a consistent and predictable order.

The patterns may repeat or vary in a systematic way, creating a sense of rhythm, symmetry, or harmony.

We have,

From the series of patterns, we see that,

The number of arrows is increasing in odd arithmetic numbers.

So,

1, 3, 5,

The next step must have 7 arrows.

And,

The color is alternated as:

Red, Blue, Red Blue.

So,

The next step in the series must be a blue color.

Thus,

The most likely next step in the series is Option B.

Answer:

-2 or 2

Step-by-step explanation:

So we have the equation:

[tex]x^2-4=0[/tex]

Add 4 to both sides:

[tex]x^2=4[/tex]

Take the square root of both sides:

[tex]x=\pm 2[/tex]

The confidence interval is  (0.1008, 0.1792)

Step-by-step explanation:

According to the question, the data provided is as follows

p′=0.14

sampling standard deviation of σp′= 0.02

Based on the above information

The computation of the 95% confidence interval for the true or correct proportion is

Here we apply the z value of 95% confidence interval i.e. 1.96

Now the confidence interval is

[tex]= (pcap - z\times sigma, pcap + z\times sigma)\\\\= (0.14 - 1.96\times 0.02, 0.14 + 1.96\times 0.02)\\\\= (0.1008, 0.1792)[/tex]

Sea level starts at 0m

Since we start at 0 and it is 20m above sea level, we can add.

0 + 20 = 20m

Therefore, the elevation is 20m

Answer:

Answer: The answer is (B) 48.5%.

Step-by-step explanation: Given that a number cube is rolled with the results that 64 ones, 67 twos, 73 threes, 59 fours, 72 fives, and 71 sixes appears. We are to calculate the experimental probability of rolling an even number.

The number of ways in which an even number is rolled is given by

and the total number of ways is given by

Therefore, the required probability is given by

Thus, (B) is the correct answer.
