Factor the expression.
4xy + 18ry²

Answers

Answer 1

Answer:

2y ( 2x + 9ry)

Step-by-step explanation:

A.) Find the greatest common factor and factor out:

(2y x 2x) + (2y x 9ry) = 2y ( 2x + 9ry )

or

B.) Expand each expression:

4xy = ( 2 x 2 x X x y )

18ry^2 = ( 2 x 3 x 3 x r x y x y )

( 2 x 2 x X x y ) + ( 2 x 3 x 3 x r x y x y )

Then, take out like terms and put the expanded factors back together:

2y ( 2 x X + 3 x 3 x r x y ) = 2y ( 2x + 9ry )

Hope this helps!

a car valued at $28,000 depreciates at a rate of 20% per year. what will the car be worth after 6 years?

Answers

The value of the car after 6 years will be $7340  .

The Depreciation can be calculated using the formula

A = P( 1 - r/100)ⁿ

where , A = amount , P = principal , r = rate of deprecation , n = time period

In the question ,

it is given that

the value of the car (P) = $28000

rate of deprecation (r) = 20% per year

time period (t) = 6 years

Substituting the values in the Depreciation formula we get ,

Amount = 28000*( 1 - 20/100 )⁶

= 28000*(80/100)⁶

= 28000*(0.80)⁶

= 28000*0.26214

= 7339.92

≅ 7340

Therefore , the value of the car after 6 years will be $7340 .

a magician designed an unfair coin so that the probability of getting a head on a flip is $60\%$. if he flips the coin three times, what is the probability that he flips more heads than tails? express your answer as a common fraction.

Answers

Probability of getting a head is 60%

More heads than tails means these possibilities are

2 Heads - 1 Tail

3 Heads - 0 Tails

Probability of 2 Heads and 1 Tail =   C (3,2) (.60) ^2 (.40)  

=3 * (.36) (.40)  

=3 * .144

=3 (144/1000)  

=3 (18/125)

=54/125

Probability of 3 Heads = (.60) ^3

= .6 (.36)

= .216 = 216 / 1000

= 27 / 125

Hence, total probability =   54 / 125 + 27 / 125

= 81 / 125

Answers

The approximate angle will be made by the stairway with the ground is 46.24°.

As we are been given that, the length of the stairway from the ground is 18 feet, under the right angle triangle, that will be the length of the hypotenuse. Next, since the elevation of the top of the stairway from, the ground is 13 feet, which is considered to be the length of the perpendicular of the assumed right angled triangle.

Now, we are asked to find the angle x,

Since, we know  that

                      sin θ = perpendicular/ hypotenuse

So, substituting the required values the desired angle we get is :

                            sin θ = 13/18

                            sin θ = 0.7222

                              θ  = sin ⁻¹ (0.7222)

                                  = 46.2364

Which points are solutions of the inequality?

We want to find points of the form (x, y) that are solutions of the inequality:

Clearly x and y must be different than zero.

So, for example if x = -1, y can be any negative number, for example y= -3

Step-by-step explanation:

Let ς₁ be the circle of equation :

and ς₂ be the circle of equation :

ς₂ : (x + 2)² + y² = 4 

Consider the point M (x , y) ∈ ς₁∩ς₂

M  ∈ ς₁ ⇔ (x - 2)² + y² = 4

M  ∈ ς₂ ⇔ (x + 2)² + y² = 4

M (x , y) ∈ ς₁∩ς₂ ⇒ (x - 2)² + y² = (x + 2)² + y²

⇒ (x - 2)² = (x + 2)²

⇒ x² - 4x + 4 = x²+ 4x + 4

⇒  - 4x = 4x

⇒  8x = 0

⇒  x = 0

Substitute x by 0 in the first equation:

(0 - 2)² + y² = 4

⇔ 4 + y² = 4

⇔ y² = 0

⇔ y = 0

Conclusion:

The two circles intersect at one and only point A(0 , 0).

Event can be defined as a set of outcomes of an experiment. In other words, an event in probability is the subset of the respective sample space. So, what is sample space? The entire possible set of outcomes of a random experiment is the sample space or the individual space of that experiment

corporation uses trucks to transport bottles from the warehouse to different retail outlets. gasoline costs are per mile driven. insurance costs are per year. calculate the total costs and the cost per mile for gasoline and insurance if the truck is driven​ (a) miles per year or​ (b) miles per year. ​(round the cost per mile to the nearest​ cent, $x.xx.)

Answers

The total cost = $5000 (Option A) and $9400 (Option B)

Cost per mile = $0.33 (option A) and $0.25 (Option  B)

What is unitary method?

A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.

Given:

Cost of gasoline for each mile driven = $0.20Cost of insurance for each year = $2000

To find: Total costs and cost per mile, when the truck is driven (A) 15000 miles per year (B) 37000 miles per year.

Finding:

(A) By unitary method,

When the truck is driven 1 mile, cost of gasoline = $0.20

When the truck is driven 15000 miles, cost of gasoline = $ 0.20(15000) = $3000 in an year

Cost of insurance in an year = $2000

Thus, total cost = $ 3000 + $2000 = $5000

Now, for per mile cost:

Cost of gasoline = $0.20

Cost of insurance = $0.13

Thus, Cost per mile = $0.20 + $0.13 = $0.33

(B) Again, by unitary method,

When the truck is driven 1 mile, cost of gasoline = $0.20

When the truck is driven 37000 miles, cost of gasoline = $ 0.20(37000) = $7400 in an year

Cost of insurance in an year = $2000

Thus, total cost = $ 7400 + $2000 = $9400

Now, for per mile cost:

Cost of gasoline = $0.20

Cost of insurance = $0.5

Thus, Cost per mile = $0.20 + $0.5 = $0.25

A. divide 2x by 2

B. add 5 to both sides of the equation

C. divide both sides of the equation by 26

D. subtract 5 from the left side of the equation

Answers

Tom’s first step should be to add 5 to both sides to cancel it out and combine with the other constant of 26. He must do this to isolate the variable.

Find the distance between each pair of points. Round to one decimal place. A(-4, 6) and B(3, -7), and E(-6, -5) and F(2, 0).

Answers

To one decimal place, round. points A(-4, 6), B(3, -7), E(-6, -5) and F (2, 0).

The distance between AB is [tex]\sqrt{185}[/tex]=13.601 and EF is [tex]\sqrt{89}[/tex]=9.433.

Given that,

To one decimal place, round.

A(-4, 6), B(3, -7), E(-6, -5) and F (2, 0).

We have to find the distance between two points that are AB and EF.

1. The distance between 2 points A and B.

A(-4, 6) and B(3, -7).

Distance formula is [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

Here, x₁=-1,x₂=3 and y₁=6,y₂=-7

After substituting we get,

[tex]\sqrt{{(3 -(-1)} )^{2} +(-7 -6 )^{2} }\\[/tex]

[tex]\sqrt{{(3 +1} )^{2} +(-7 -6 )^{2} }\\[/tex]

[tex]\sqrt{{(4} )^{2} +(-13 )^{2} }\\[/tex]

[tex]\sqrt{16 +163}\\[/tex]

[tex]\sqrt{185}[/tex]

13.601

Therefore, the distance between AB is [tex]\sqrt{185}[/tex]=13.601.

2.The distance between 2 points E and F.

E(-6, -5) and F (2, 0).

Distance formula is [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

Here, x₁=-6,x₂=2 and y₁=-5,y₂=0

After substituting we get,

[tex]\sqrt{{(2 -(-6)} )^{2} +(0 -(-5) )^{2} }\\[/tex]

[tex]\sqrt{{(2 +6} )^{2} +(0 +5 )^{2} }\\[/tex]

[tex]\sqrt{{(8} )^{2} +(5 )^{2} }\\[/tex]

[tex]\sqrt{64 +25}\\[/tex]

[tex]\sqrt{89}[/tex]

9.433

Therefore, the distance between EF is [tex]\sqrt{89}[/tex]=9.433.

why does the inequality sign have to be flipped when dividing by a negative number?

Answers

The inequality sign have to be flipped when dividing by a negative number.

What is inequality?

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.

Given:

The given statement is the inequality sign have to be flipped when dividing by a negative number.

According to given question we have

A number that is larger when positive becomes "more negative," and thus smaller when negative, and vice versa.

Dividing by a negative number is the same as dividing by a positive number and then multiplying by −1. Dividing an inequality by a positive number retains the same inequality. But, multiplying by −1 is the same as switching the signs of the numbers on both sides of the inequality, which reverses the inequality:

a<b⟺−a>−b.

Ex:

when dividing both sides by a negative number, we reverse the inequality sign.

Take −3x<9

To solve for x, we divide both sides by −3 and get

x>−3.

Therefore, the inequality sign have to be flipped when dividing by a negative number.
