Answer:

[tex]x=-4\pm\sqrt5[/tex]

Step-by-step explanation:

So we have the equation:

[tex]x^2+8x+11=0[/tex]

First, subtract 11 from both sides:

[tex]x^2+8x=-11[/tex]

Now, add the c term. Divide 8 by 2 and then square it:

[tex](x^2+8x+16)=-11[/tex]

What we do to one side we must also do to the other. Thus:

[tex](x^2+8x+16)=-11+16[/tex]

Simplify:

[tex](x^2+8x+16)=5[/tex]

Perfect Square Trinomial:

[tex](x+4)^2=5[/tex]

Take the square root:

[tex]x+4=\pm\sqrt5[/tex]

Subtract 4:

[tex]x=-4\pm\sqrt5[/tex]

And that's our answer :)

Answer:

6

Step-by-step explanation: think of it this way. When you adding a positive to a negative, you simply taking the negative away from the positive. So in this case, you are subtracting 2 from 8 to get six. Or, its the difference between the positve and the negative!! Hope this helps!

the answer is -4

Step-by-step explanation:

Answer:

(x-1)²/64 + (y-2)²/144 = 1

Step-by-step explanation:

The standard equation of an ellipse is expressed as (x-h)²/a² + (y-k)²/b² = 1

Where the coordinate (h,k) is the centre of the ellipse.

a is the the difference of the x coordinates of the centre and the vertex.

b is the minor axis.

Given the centre to be (1,2), on comparing with the coordinate (h,k),

h = 1 and k = 2

The difference of the x coordinates of the centre and the vertex = -7-1 = -8

The minor axis as given in the equation is b = 12

Substituting the given parameters into the equation of an ellipse above we will have;

(x-1)²/(-8)² + (y-2)²/12² = 1

(x-1)²/64 + (y-2)²/144 = 1

The final equation gives the required standard form of the equation of the ellipse.

Answer:

For the code we have 3 selections.

The first selection is a digit that must be odd, so the options are {1, 3, 5, 7 ,9}

So we have 5 options.

The second selection is a letter from the set of all the letters (27) minus the set of the vowels (5)

So here we have 27 - 5 = 22 options

The third selection is also a letter from the previous set, but because each letter can be used only one time, and in the previous selection we already selected one of the letters, in this selection we have a letter less than in the previous selection.

Here we have 22 - 1 = 21 options.

The total number of combinations (of possible codes) is equal to the product of the number of options for each selection:

C = 5*22*21 = 2310.

There are 2310 different possible codes

Answer:

(0, -5) and (4, 3)

Step-by-step explanation:

I assume you're looking for the coordinates of the intersections, if any.

Solve by substitution:

x² + (2x − 5)² = 25

x² + 4x² − 20x + 25 = 25

5x² − 20x = 0

5x (x − 4) = 0

x = 0 or 4

So the coordinates are (0, -5) and (4, 3).

Answer:

Step-by-step explanation:

Let us denote probability of   spoilage as follows

Transformer spoilage = P( T ) ; line spoilage P ( L )

Both P ( T ∩ L ) .

Given

P( T )  = .05

P ( L ) = .08

P ( T ∩ L ) = .03

a )

For independent events

P ( T ∩ L ) =  P( T ) x  P ( L )

But  .03  ≠  .05 x .08

So they are not independent of each other .

b )

i )

Probability of line spoilage given that there is transformer spoilage

P L/ T ) = P ( T ∩ L ) / P( T )

= .03 / .05

= 3 / 5 .

ii )

Probability of transformer spoilage but not line spoilage.

P( T ) - P ( T ∩ L )

.05 - .03

= .02

iii )Probability of transformer spoilage given that there is no line spoilage

[ P( T ) - P ( T ∩ L ) ] / 1 - P ( L )

=  .02 / 1 - .08

= .02  / .92

= 1 / 49.

i v )

Neither transformer spoilage nor there is no line spoilage

= 1 - P ( T ∪ L )

1 - [  P( T ) +  P ( L ) - P ( T ∩ L ]

= 1 - ( .05 + .08 - .03 )

=  0 .9

Answer:

  centimeter

Step-by-step explanation:

Miles is a measure of distance, so the commensurable measure will also be a distance measure.

  acres - area measure

  kilograms - mass measure

  hours - time measure

  centimeter - distance measure

Using the commensurable units concept, it is found that centimetres is commensurable with miles.

Answer:

23,817$

Step-by-step explanation:

And you will have earned 13,817 in interest.

The final amount of money $10000 of 7.5% compound interest for 12 years is $23817.79.

Compound interest is applicable when there will be a change in principal amount after the given time period.

If you give anyone $500 at the rate of 10% annually then $500 is your principle amount.

Given that,

Principle amount P = $10000

Rate of interset R = 7.5% = 0.075

Time period T = 12 years

Compound interest formula ;

A = P[1+R]^T

A = 10000[1+0.075]¹²

A = $23817.79

Hence "The final amount of money $10000 of 7.5% compound interest for 12 years is $23817.79".

Answer:

The scale factor is 1/48

Step-by-step explanation:

First, we need to convert 60 feet to inches.

60 feet = 720 inches

Then, we divide 720 by 15

720/15= 48.

The scale factor is 1/48.

The scale factor of dilation is given by the proportion and A = 48

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

We can use the ratio of the lengths of the corresponding sides to find the scale factor or dilation factor used by the architect.

Let A be the factor of dilation used by the architect. Then we can set up the following proportion:

60 feet / A = 15 inches / 1

We can solve for x by cross-multiplying:

60 feet x 1 = A x 15 inches

A = (60 feet) / (15 inches)

We need to convert feet to inches to get the units to match:

A = (60 feet) / (15 inches) x (12 inches / 1 foot)

Simplifying, we get:

A = 720 / 15

A = 48

Hence , the architect used a scale factor of 48 when creating the scale drawing of the house

Answer:

x = 4

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write equation

4(x + 2) = x - 4

Step 2: Distribute

4x + 8 = x - 4

Step 3: Subtract 8 on both sides

4x + 8 - 8 = x - 4 - 8

4x = x - 12

Step 4: Subtract x on both sides

4x - x = x - x - 12

3x = 12

Step 5: Divide both sides by 3

3x/3 = 12/3

x = 4

Final Answer:

x = -4

Step-by-step explanation:

step 1 Simplify both sides of the equation:

4(x + 2) = x - 4

(4)(x) + (4)(2) = x + (-4)

4x + 8 = x + (-4)

step 2 Subtract x from both sides:

4x + 8 - x = x - 4 - x

3x + 8 = -4

step 3 Subtract 8 from both sides:

3x + 8 - 8 = -4 - 8

3x = -12

last step Divide both sides by 3:

3x      -12

Answer:

Ms. Rangtonsmith will get $30 after raise

Step-by-step explanation:

Current salary = $25

raise = 1/5 of current salary

substituting current salary with $25

raise in dollar value = 1/5 of $25 = 1/5 *$25 = $5

Thus, raise is $5

total salary after raise will be sum of current salary and raise

total salary after raise = $25 + $5 = $30

Thus, Ms. Rangtonsmith will get $30 after raise
