A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers

Step-by-step explanation:

Final answer:

A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. Prime numbers have many interesting properties and applications in mathematics.

Explanation:

A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. In other words, it is a number that is only divisible by 1 and itself.

For example, the numbers 2, 3, 5, and 7 are prime numbers because they have no divisors other than 1 and themselves. On the other hand, the number 4 is not prime because it is divisible by 1, 2, and 4.

Prime numbers have many interesting properties and applications in mathematics, including their role in number theory and cryptography.

Answer:

75

Step-by-step explanation:

Geometric means you should think common ratio (words like multiplication or division).

First term=3

Second term=15

What can you multiply to first to give you second term? Please say 5! Yes 5! Why? Because 3*5=15.

So 5 is called the common ratio.  5 is the number that you will multiply to a term to find the very next term.

So the third term would be 15*5=75

The next value in the geometric sequence is 75.

A geometric sequence is a sequence of numbers in which each term can be found by multiplying the previous term by a fixed, non-zero number called the common ratio. In this case, to find the next value in the sequence, we need to determine the common ratio. We can divide the second term (15) by the first term (3) to find the common ratio:

Common ratio = 15/3 = 5

Now that we know the common ratio is 5, we can find the third term in the sequence:

Third term = Second term × Common ratio = 15 × 5 = 75

Step-by-step explanation:

it is opening downwards so the number multiplying the function must be negative (in this case it is -2)

Answer:

y = -2(x -­ 1)² + 2

Step-by-step explanation:

recall that the vertex form of a quadratic equation is :

y = a(x - h)² + k, where (h, k) is the coordinate of the vertex (i.e maxima point)

from the graph we can see that the vertex is at x = 1, y = 2

hence the answers that are valid would have h = 1 and k = 2

right away by observing the answers, we can see that the last 2 choices have h = (-1) and so these are NOT the answers.

To decide between the first 2 choices, we observe from the given graph, that when x=0, y=0.

The only choice which satisfies this is the 2nd option

Proof:

for y = -2(x -­ 1)² + 2, when x = 0,

y = -2(0 -­ 1)² + 2

y = -2(-­ 1)² + 2

y = -2(1) + 2 = -2 + 2 = 0 (Proven to be valid)

Sanity check: check the first choice

y = (x ­- 1)² + 2

when x = 0,

y = (0- 1)² + 2

y = 1 + 2 ≠ 0 (not the answer)

Answer:

The average power use is 806 watts....

Step-by-step explanation:

We all know that there are 31 days in May.

To find the total number of hours in 31 days, multiply the hours of one day by 31.

31*24 = 744 hours

Now we have given 600.kilowatt

To find average power, simply divide the given kilowatt by the total number of hours in 31 days.

= 600/744

Average power = 0.806 kilowatt

Since they have asked for the answer in watts we will convert kilowatt into watts.

We know that 1000 watts = 1 kilowatt, so we will multiply 0.806 by 1000 to convert it into watts

= 0.806*1000

= 806 watts.

Therefore the average power use is 806 watts....

               =3/4 !

Answer:

The value of P(S or T) is 3/4.

Step-by-step explanation:

It is given that S and T are mutually exclusive events. It means intersection of S and T is 0.

[tex]S\cap T=0[/tex]

[tex]P(S\cap T)=0[/tex]

We need to find the value of  P(S or T). It means we have to find the probability of union of S and T.

The 4th day so 21 miles the girls would have to run

Step-by-step explanation:

Answer:

Each girl would have ran a total of 21 miles and boys would have ran a total of 20 miles by the end of the fourth day before the couch order new javelins.

Step-by-step explanation:

Girls track team

First day of practice=3 miles

Days afterwards= 6 miles

Boys track team

Everyday= 5 miles

coach will order new javelins at the end of the day that each girl's total mileage surpasses each boy's.

First day

Each girl total mileage= 3 miles

Each boy total mileage= 5 miles

Second day

Each girl total mileage= 3miles+6miles=9 miles

Each boy total mileage=5 miles+5 miles= 10 miles

Third day

Each girl total mileage= 3+6+6=15 miles

Each boy total mileage=5+5+5=15 miles

Fourth day

Each girl today mileage= 3+6+6+6=21 miles

Each boy total mileage=5+5+5+5= 20 miles

Difference=girls-boys

=21-20= 1 mile

The fourth day is the day each girl's total mileage(21 miles) surpasses each boy's total mileage(20 miles) with a total of 1 mile

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

The equations;

–7x + 8y = 1

4x – 8y = 20

Now,

To solve this system of equations, we can use the elimination method. We can multiply the first equation by 2 and add it to the second equation to eliminate y:

-14x + 16y = 2 +4x - 8y = 20

-10x = 22

x = -2.2

Now that we have x, we can substitute it into either equation to solve for y. Let’s use the first equation:

-7x + 8y = 1 -7(-2.2) + 8y = 1 15.4 + 8y = 1 8y = -14.4 y = -1.8

Therefore, the solution to the system of equations will be (x, y) = (-2.2, -1.8) the y-coordinate will be -1.

Step-by-step explanation:

You can solve this by adding up .5 8 times to equal 4. Another way to look at it is that you have 4 individual pieces that are a foot long and you decide to split all of them in half. Let me know if you have any other questions.

Answer:

The equation that shows that is the division between 4 and 0.5 as:

[tex]\frac{4}{0.5}[/tex]

Step-by-step explanation:

First, it is necessary to know that one half foot is equivalent to 0.5 foot.

We can solve this using a rule of three in which we know that 1 piece has one half foot long, then 4 foot long how many pieces have. This is:

1 board -----------  0.5 foot

 X        ------------  4 foot

Where X is the number of pieces that he can get from a four foot long board.

Solving for X, we get:

[tex]X  = \frac{4*1}{0.5} = \frac{4}{0.5}[/tex]

So, the equation that shows how many one half foot pieces he can get from a four foot long board is:

Answer:

  x = 29° + n·120° . . . or . . . 261° +n·360° . . . . for any integer n

Step-by-step explanation:

Multiplying by the denominator, the equation becomes ...

  sin((x -3)°) = cos((2x+6)°)

The sine and cosine are equal when ...

  (x -3) + (2x +6) = 90 + n·360 . . . . . for any integer n

  3x +3 = 90 + n·360 . . . . . . . . . collect terms

  x +1 = 30 +n·120 . . . . . . . . . . . .divide by 3

  x = 29 + n·120 . . . . . . . . . . . . . . subtract 1

__

The sine and cosine are also equal when ...

  (x -3) -(2x +6) = 90 + n·360

  -x -9 = 90 +n·360

  x = -99 -n·360

Since n can be any integer, this can also be written as ...

  x = 261 + n·360

Possible values of x include {29, 149, 261, 269} +n·360 for any integer n.

Step-by-step explanation:

In this problem angle of 38 degrees and angle of 52 degrees are complementary angles

so

38°+52°=90°

therefore

cos(38°)=sin(52°)

we know that

see the attached figure with letters to better understand the problem

In the triangle ABD

cos(38°)=24/x ----> The cosine of angle of 38 degrees is equal to divide the adjacent side to angle of 38 degrees by the hypotenuse

Remember that

cos(38°)=sin(52°)

so

sin(52°)=24/x

In the right triangle ABC

cos(38°)=x/34 ----> The cosine of angle of 38 degrees is equal to divide the adjacent side to angle of 38 degrees by the hypotenuse

In the right triangle ABD

Applying the Pythagoras Theorem

[tex]BD=\sqrt{x^{2}-576}\ units[/tex]

[tex]cos(52\°)=(\sqrt{x^{2}-576})/x[/tex]----> The cosine of angle of 52 degrees is equal to divide the adjacent side to angle of 52 degrees by the hypotenuse

Answer:

16 N

Step-by-step explanation:

If the 7 N force is at 0°, and the 11 N force is at 60°, then the components of the resultant force are:

Fₓ = 7 cos 0° + 11 cos 60° = 12.5

Fᵧ = 7 sin 0° + 11 sin 60° ≈ 9.53

The magnitude of the resultant force is:

F = √(Fₓ² + Fᵧ²)

F ≈ 15.7

Rounded to the nearest whole number, the magnitude is 16 N.
