Answer:

x >= -7  ................(1a)

x >= 3   ...............(2a1)

Step-by-step explanation:

f(x) =  [tex]\sqrt{x+7}-\sqrt{x^2+2x-15}[/tex]  .............(0)

find the domain.

To find the (real) domain, we need to ensure that each term remains a real number.

which means the following conditions must be met

x+7 >= 0  .....................(1)

AND

x^2+2x-15 >= 0 ..........(2)

To satisfy (1),  x >= -7  .....................(1a) by transposition of (1)

To satisfy (2), we need first to find the roots of (2)

factor (2)

(x+5)(x-3) >= 0

This implis

(x+5) >= 0 AND (x-3) >= 0.....................(2a)

OR

(x+5) <= 0 AND (x-3) <= 0 ...................(2b)

(2a) is satisfied with x >= 3   ...............(2a1)

(2b) is satisfied with x <= -5 ................(2b1)

Combine the conditions (1a), (2a1), and (2b1),

x >= -7  ................(1a)

AND

(

x >= 3   ...............(2a1)

OR

x <= -5 ................(2b1)

)

which expands to

(1a) and (2a1)   OR  (1a) and (2b1)

( x >= -7 and x >= 3 )  OR ( x >= -7 and x <= -5 )

Simplifying, we have

x >= 3  OR ( -7 <= x <= -5 )

Referring to attached figure, the domain is indicated in dark (purple), the red-brown and white regions satisfiy only one of the two conditions.

Answer:

Hey there!

We have an=a1(r^n-1), which is the formula for a geometric sequence.

The common ratio is 3, and 2 is the 1st term.

Thus, we have a1=2(3)^(n-1)

Hope this helps :)

Answer:

The sample proportion, p, of gun owners who own gun for protection is 0.67

Step-by-step explanation:

The information given are;

The sample size = 3930

The number of individuals who reported that they owned guns at least on gun = 1269

The number of the self reported gun owners that said the reason they owned gun for protection = 850

The sample proportion, p, of gun owners who own gun for protection is given as follows;

p = (The number of the self reported gun owners that said the reason they owned gun for protection )/(The number of individuals who reported that they owned guns at least on gun)

p = 850/1269 = 0.6698 ≈ 0.670 (to three decimal places)

Therefore, the sample proportion, p, of gun owners who own gun for protection = 0.67.

Explanation : If 66 is a factor of this unknown value, then 22 must be as well considering that 22 is a factor off 66. Let's say that this large value is 330. It is a multiple of 66, as 66 [tex]*[/tex] 5 = 330. At the same time 22 [tex]*[/tex] 15 = 330, so 330 is a multiple of 22 as well - or vice versa, 12 is a factor of 330.

We can also tell that 15, 22 fit into 330 through another approach. 22 [tex]*[/tex] 3 = 66, and 66 [tex]*[/tex] 5 = 330, so 5 [tex]*[/tex] 3 = 15 - the same value. This proves that 22 will always be a factor of a value that is the factor of 66.

Answer:

Surface Area = 392 cm²

Step-by-step explanation:

Green (front):

SA = 1/2bh

= 1/2 (12) (8)

= 48 cm²

Green (left side):

SA = bh

= 5 (10)

= 50 cm²

Green (right side):

SA = bh

= 5 (10)

= 50 cm²

Green (back):

SA = 1/2bh

= 1/2 (12) (8)

= 48 cm²

Blue (front):

SA = bh

= 12 (4)

= 48 cm²

Blue (left side):

SA = cm²

= 5 (4)

= 20 cm²

Blue (right side):

SA = bh

= 5 (4)

= 20 cm²

Blue (back):

SA = bh

= 12 (4)

= 48 cm²

Blue (bottom):

SA = bh

= 12 (5)

= 60 cm²

Total:

48 + 50 + 50 + 48 + 48 + 20 + 20 + 48 + 60 = 392 cm²

Answer:

So we have a function such that:

Takes elements of Set A, and maps them into Set B.

So Set A is the domain, and Set B is the range.

Where the domain is defined as the set of all the possible inputs of a function, and the range is the set of the possible outputs.

In principle, yes, if f(x) maps Set A into Set B, all the elements of Set A should be used, why?

Because we need to check if there is a problem with Set A, for example the function f(x) = 1/x has a problem when x = 0, so we remove x = 0 from the domain of that function.

So, a function is only a function if it maps ALL the elements of its domain into only one element in the range.

Answer:

x^ -10

Step-by-step explanation:

x^2 * x ^ -12

We know that a^b * a^c = a^ (b+c)

x^2 * x^-12

x^(2+-12)

x^ -10

Answer:

[tex]\frac{1}{x^{10}}[/tex]

Step-by-step explanation:

The two "x" terms are being multiplied, so combine the terms

Subtract the power signs:

[tex]x^2 * x^-12[/tex] = [tex]x^2/x^{12}[/tex]

[tex]x^(2 - 12)[/tex] = [tex]x^-10[/tex]

[tex]x^-10[/tex] = [tex]\frac{1}{x^{10}}[/tex]

[tex]\frac{1}{x^{10}}[/tex] is your answer.

Answer:

pythagorean theorem - The length of the hypotenuse squared will always equal the sum of A squared and B sqaured. The equation is A^2 + B^2 = C^2.

Step-by-step explanation:

For Example

A = 4      A^2 = 16

B = 2      B^2 = 4

C = ?      C^2 = ?

16 + 4 = 20

[tex]\sqrt{20}[/tex] ≈ 4.5

C/Hypotenuse = 4.5

Answer:

[tex]\huge\boxed{x = 6 , y = -2}[/tex]

Step-by-step explanation:

[tex]\sf \frac{1}{2} x - 3y = 9-----------(1)\\5x + y = 28 ----------(2)[/tex]

Taking equation (1)

[tex]\sf \frac{1}{2} x -3 y=9[/tex]

Multiplying both sides by 2

[tex]\sf x-6y = 18[/tex]

Adding 6y to both sides

[tex]\sf x = 18+6y[/tex]

Putting this in (2)

5(18+6y) + y = 28

5(18+6y) + y = 28

90 + 30y+y = 28

31y+90-28 = 0

31 y + 62 = 0

31y = -62

Dividing both sides by 31

y = -2

Now,

x = 18 + 6y

x = 18+6(-2)

x = 18-12

x = 6

Answer:

y<-8

Step-by-step explanation:

y<-1 - 7

y<-8

Answer:

y < -8

Step-by-step explanation:

To solve an inequality, we must get the variable, y, isolated on one side of the inequality.

[tex]y+7 < -1[/tex]

7 is being added to the variable, y. The inverse of addition is subtraction. Subtract 7 from both sides of the inequality.

[tex]y+7-7< -1-7[/tex]

[tex]y < -1-7[/tex]

[tex]y < -8[/tex]

The solution to the inequality is: y< -8

Answer:

A

Step-by-step explanation:

A: 0^2+8=8

B: 1^2+8=9

C: 2^2+8=12

D: 3^2+8=17

as 8 is the smallest, A is the answer

Any rectangle is also a parallelogram (but not the other way around). So AB is parallel to CD. The angles BAC and ACD are alternate interior angles that are congruent due to the parallel sides mentioned.

(angle BAC) = (angle ACD)

3x+4 = x+28

3x-x = 28-4

2x = 24

x = 24/2

x = 12

So,

angle BAC = 3x+4 = 3*12+4 = 40 degrees

and

angle CAD = 90 - (angle BAC) = 90 - 40 = 50 degrees

With any rectangle, the four interior angles are always 90 degrees. So that's why angles BAC and CAD add to 90.

Answer:

three solutions:  {-3, -3, 0}

Step-by-step explanation:

This polynomial has already been factored, and the factors are x, x + 3 and x = +3.  To solve this equation, set each of the factors equal to zero separately and solve each of the resulting equations:

x = 0 is a solution; the given equation equals zero when x = 0.

The next factor is x + 3; setting this equal to 0 yields the solution x = -3.

The last factor is x + 3; x = -3 is the third solution.

In summary, (x + 3)(x = 3) = 0 has two solutions; we call them "repeated roots."    x(x + 3)(x = 3) = 0 has three solutions:  {-3, -3, 0} of which two are "repeated."
