Positive integer A has 2 different prime factors: p and q (p<q) such that A = pq. Positive integer B is greater than A and the quotient A^2/B is an integer. How many possible values of B are there? PLEASE GIVE AN EXPLANATION WITH YOUR ANSWER! ​

Answer:

Option B R(2,4) is correct

Step-by-step explanation:

The equation of the circle is:

[tex](x-a)^2 + (y-b)^2 = r^2[/tex]

Where r = radius

a and b are coordinates of the center of circle.

To check which point lies on a circle, we need to verify the equation

[tex](x-6)^2 + (y-1)^2 = (5)^2[/tex]

We will check for each option.

Option A Q(1,11)

x=1 and y =11

[tex](1-6)^2 + (11-1)^2 = 25\\(-5)^2 + (10)^2 = 25\\25 + 100 = 25\\125 \neq 25[/tex]

So, Option A is incorrect

Option B R(2,4)

x =2 and y = 4

[tex](2-6)^2 + (4-1)^2 = 25\\(-4)^2 + (3)^2 = 25\\16 + 9 = 25\\25 = 25[/tex]

Option B is correct.

Option C S(4,-4)

x =4 and y =-4

[tex](4-6)^2 + (-4-1)^2 = 25\\(-2)^2 + (-5)^2 = 25\\4 + 25 = 25\\29 \neq 25[/tex]

Option C is incorrect

Option D T(9,-2)

x =9 and y =-2

[tex](9-6)^2 + (-2-1)^2 = 25\\(3)^2 + (-3)^2 = 25\\9 + 9 = 25\\18 \neq 25[/tex]

Option D is incorrect.

Answer:

B.

Step-by-step explanation:

The general equation of a circle is [tex](x-h)^{2}+(y-k)^{2} = r^{2}[/tex] where (h,k) is the center and r the radius. In this case, the general equation of the circle with radius 5 and center at (6,1) is [tex](x-6)^{2}+(y-1)^{2} = 5^{2}[/tex], so the point that satisfies the equation will be in the circle.

A.  [tex](1-6)^{2}+(11-1)^{2} = 25+100 = 125[/tex] this option is not correct.

B.   [tex](2-6)^{2}+(4-1)^{2} = 16+9= 25[/tex] this option is correct so is the answer.

Answer:

x>-18

Step-by-step explanation:

Answer:

Option D.

Step-by-step explanation:

We will solve the given equation and compare it with the solution of Amit's solution.

[tex]\frac{5}{12}=-\frac{x}{420}[/tex]

We will multiply by (-420) on both the sides of the equation.

[tex]\frac{5}{12}(-420)=-\frac{x}{420}(-420)[/tex]

-175 = x

By comparing the solutions we find that the product of [tex]\frac{5}{12}[/tex] and (-420) should have been the value of x, while Amit multiplied the equation by (420).

Therefore, Option D. is the correct option.

Answer:

A and B

Step-by-step explanation:

We can add 48 to both sides of the equation to get

3x^2 = 48

Dividing by 3 on both sides,

x^2 = 16

Taking the square root of both sides,

x = +/- 4

So A and B are our answers.

Answer: Option A and Option B

[tex]x=4[/tex] and [tex]x=-4[/tex]

Step-by-step explanation:

We must find the solutions of the following equation

[tex]3x^2-48=0[/tex]

Add 48 on both sides of the equality

[tex]3x^2-48+48=48[/tex]

[tex]3x^2=48[/tex]

Divide both sides of equality by 3

[tex]\frac{3}{3}x^2=\frac{48}{3}[/tex]

[tex]x^2=16[/tex]

Apply the square root on both sides of the equation

[tex]x=\±\sqrt{16}[/tex]

[tex]x=4[/tex] and [tex]x=-4[/tex]

Answer:

C. two thirds x + 10 = 21

Step-by-step explanation:

Given

Price of adult ticket = $21.00

Let x be the price of student ticket

Then

two third of the student ticket will be:

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

The statement $10.00 more than two third of student ticket:

[tex]\frac{2}{3} x+10[/tex]

As we are given in the question that the adult ticket price is $21.00 and the second explanation is th equation formed by the given statement

So, both will be equivalent

[tex]\frac{2}{3} x+10 = 21[/tex]

Solving this equation for x will give us the price for the student ticket.

Hence,

C. two thirdsx + 10 = 21 is the correct answer ..

y intercept = 5

Step-by-step explanation:

f(x)=5•(1/6)^x

The y intercept is when x =0

Let x =0

f(0)=5•(1/6)^0      

= 5* 1     = 5

The y intercept is 5

If the question is

f(x)=5•(1/6)x

although I have never seen the question written this way

The y intercept is when x =0

Let x =0

f(0)=5•(1/6)0      

= 5* 0     = 0

The y intercept is 0

Answer:

Many possible answers, including

Major Arc: JKM

Minor Arc: JM

Step-by-step explanation:

The answers you selected in this photo are correct. But let's see why.

A major arc is an arc that is bigger than a minor arc.

They are defined using a starting point and an ending point.  In this case, you have many reference points (J, K, L and M), and none is identified in the question.  However, the answers shown indicate they're using point J as starting point and M as ending point.

If you look at the positions of J and M on the diagram, you see you can take two routes to join them... the shortest route is the minor arc (going counter-clockwise direction from J to M).  While the other route, going clockwise passes through the points K and L is much longer.... and forms the major arc.

That major arc could be identified as JKM, JLM or JKLM, since it starts at J, ends in M, but passes through points K and L, in that order.

Answer:

40 MPH (Miles Per Hour)

Step-by-step explanation:

Well i will put it in simple terms. Put 2/3 into a decimal point, which for this fraction is 0.66666666667 (the 6 is infinite basically). Then you multiply it by 60, because you know it goes in that distance in one minute and 60 minutes makes a hour, which equals 40. So the answer is 40 MPH.

40 miles per hour.

To determine how many miles per hour a bird is flying when it covers 2/3 of a mile per minute, we can follow a simple conversion. Since there are 60 minutes in an hour, we need to multiply 2/3 by 60.

Let's do the calculation:

(2/3 mile/minute) times 60 minutes/hour = 40 miles/hour

This means that when a bird flies 2/3 of a mile per minute, it is equivalent to flying at a speed of 40 miles per hour.

In case you don't have answers to select from, you generally solve this sort of problem using elimination. You can also use Cramer's rule, a graphing calculator, an on-line equation solving tool, or any of a variety of other methods.

Here, we can find the variable x by subtracting twice the first equation from the second:

  (5x +8y +6z) -2(2x +4y +3z) = (4) -2(6)

  x = -8

This is sufficient to identify the correct answer choice.

We can substitute this into the last two equations to get ...

  -40 +8y +6z = 4 . . . . 8y +6z = 44

  -32 +5y +2z = 6 . . . . 5y +2z = 38

Subtracting the first of these from 3 times the second gives ...

  3(5y +2z) -(8y +6z) = 3(38) -(44)

  7y = 70 . . . . . . . simplify

  y = 10 . . . . . . . . divide by 7

Substituting this into the second of the above equations, we have ...

  5(10) +2z = 38

  25 +z = 19 . . . . . . divide by 2

  z = -6 . . . . . . . . . . subtract 25

_____

The choice of the combinations to use to eliminate variables can be ad hoc (as here), or it can be made according to some rules (as in Gaussian elimination).

My personal choice for solving systems like this is to use the matrix functions of a graphing calculator.

Answer:

x = 5; the slope is undefined

Step-by-step explanation:

A line perpendicular to the x-axis is a vertical line.

In a vertical line, every point has a different y-coordinate and the same x-coordinate. Since you want a line that is vertical and passes through the point (5, -3), then every point on the line must have x-coordinate 5 no matter what its y-coordinate is. The slope of a vertical line is undefined.

Answer: The equation is x = 5; the slope is undefined

Answer:

x = {4, 4}

Step-by-step explanation:

(x - 4)(x - 4) = 0 has two real, equal roots:  x = 4 and x = 4.  Notice that subbing 4 for x in this equation results in a TRUE equation.

The value of x in  (x - 4)(x - 4) = 0 is x = (4, 4) repeated roots.

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

Given (x - 4)(x - 4) = 0.

∴ Either (x - 4) = 0 or (x - 4) = 0.

x - 4 = 0 ⇒ x = 4 or x - 4 = 0 ⇒ x = 4.

So, x = (4, 4).

This is a case when a quadratic equation has real repeated roots.

The vertex of this graph of this quadratic equation just touches the x-axis.

Apollo Spas would require approximately 17.325 liters of muriatic acid to service all 105 hot tubs.

The student is looking to find out the total amount of muriatic acid, noted in liters, required to service all hot tubs. The problem states Apollo Spas needs to service 105 hot tubs, with each one requiring 165 mL of acid.

Firstly, we need to multiply the number of hot tubs by the amount of acid each one needs: 105 hot tubs * 165 mL/hot tub = 17325 mL.

However, the student needs the amount in liters, not milliliters. To convert mL to L, we need to divide the total mL by 1000 because there are 1000 mL in a liter.  Therefore, 17325 mL / 1000 =  17.325 L.

So, Apollo Spas will need 17.325 liters of muriatic acid to service all 105 hot tubs.

A. -5/4, 9

Step-by-step explanation:

The solution is in the picture

Answer:

A

Step-by-step explanation:

Given

4m² - 31m - 45 = 0

Consider the factors of the product of the coefficient of the m² term and the constant term which sum to give the coefficient of the m- term

product = 4 × - 45 = - 180 and sum = - 31

The factors are - 36 and + 5

Use these factors to split the m- term

4m² - 36m + 5m - 45 = 0 ( factor the first/second and third/fourth terms )

4m(m - 9) + 5(m - 9) = 0 ← factor out (m - 9) from each term

(m - 9)(4m + 5) = 0

Equate each factor to zero and solve for m

m - 9 = 0 ⇒ m = 9

4m + 5 = 0 ⇒ 4m = - 5 ⇒ m = - [tex]\frac{5}{4}[/tex]

Answer:

Clara's body eliminated the antibiotic at the same rate as Heidi's body.

Answer:

Option. B is the answer.

Step-by-step explanation:

Clara is taking a medicine for a common cold. Table that shows the amount f(t) that was present in Clara's body after time t is

t (hours)      1             2           3            4             5

f(t) (mg)   236.5   223.73   211.65    200.22   189.41

Now we will find the explicit formula of geometric sequence.

f(1) = 236.5

and f(2) = 223.73

Therefore, common ratio of the sequence = [tex]\frac{f(2)}{f(1)}=\frac{223.73}{236.5}[/tex]=0.946

So the equation will be f(t) = [tex]236.5(0.946)^{t}[/tex]------(1)

At the same time Heidi was administered 300 mg of same medicine of the same sample.

Amount of medicine in her body f(t) after time t is shown by the equation

f(t) = [tex]300(0.946)^{t}[/tex]----(2)

By comparing these equations 1 and 2, we find common ratio is same as (0.946), which reflects the rate of elimination of the antibiotic was same for both Clara and Heidi.

Answer:

8, 36, 81, 11, 7, 1000

Step-by-step explanation:

A

Lets start with number one.

x^2 = 64.

That means that x times x equals 64.

To find x's value, simply find the square root of 64, which is 8.

So x = 8.

For the second one, the square root of x is 6.

That means that 6 x 6 = x

6 x 6 = 36.

So, x = 36.

B

For the third one, the square root of x is 9.

That means that 9 x 9 = x

9 x 9 = 81

So, x = 81.

For the fourth one, x^2 = 121

That means x times x = 121

To find x's value, simply find the square root of 121, which is 11

So, x = 11.

C

For the fifth one, x^3 = 343.

That means that x times x times x = 343

To find x's value, simply find the square root of 343, which is 7.

So, x = 7.

For the sixth and last one, the cube root of x is 10.

That means 10 x 10 x 10 = x.

10 x 10 x 10 = 1,000

So, x = 1,000

I hope this helps! :)
