Answer:

The answer to this problem is 170.300

Answer:

D.  x2 + x - 20.

Step-by-step explanation:

(x – 4)(x + 5).

= x(x + 5) -4(x + 5).

= x2 + 5x – 4x – 20.

= x2 + x - 20.

Answer:

Answer:

5

Step-by-step explanation:

Step-by-step explanation:

1a) The perpendicular bisectors pass through the midpoints of the sides of the triangle and are perpendicular to the sides.  They are the red lines.

1b) The angle bisectors pass through the vertices of the triangle and divide the angle into two equal parts.  They are the black lines.

1c) The inscribed circle is the circle inside of the triangle.  It is the blue circle.

1d) The circumscribed circle is the circle outside of the triangle.  It is the green circle.

2a) The circumcenter is the center of the circumscribed circle.  It is point H.

2b) The incenter is the center of the inscribed circle.  It is point I.

Answer:

[tex]x=140[/tex]

Step-by-step explanation:

Do not get grounded.

An angle at a point is 360°.

So, [tex]x+120+70+30=360[/tex]

[tex]x+220=360[/tex]

[tex]x=140[/tex]

Remember this All the angles around a point when added gives a 360° !

Thus,

30+ X +70+120 = 360

=> X + 220 = 360

Answer:

The way to represent this it is

[tex] 12.33 - \frac{0.27}{\sqrt{n} } < \mu < 12.33 + \frac{0.27}{\sqrt{n} } [/tex]

Step-by-step explanation:

From the question we are told that

The sample mean is

The standard deviation is

Given that the confidence level is 95% then the level of significance is mathematically represented as

[tex]\alpha = (100-95)[/tex]

[tex]\alpha = 0.05[/tex]

The critical value for [tex]\frac{\alpha }{2}[/tex] is obtained from the normal distribution table that value is

[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]

Now the margin of error is mathematically represented as

[tex]E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }[/tex]

[tex]E = \frac{0.27}{\sqrt{n} }[/tex]

Now the error range to show a 95% confidence is mathematically represented as

[tex]\= x - E < \mu < \= x + E[/tex]

           [tex] 12.33  -   \frac{0.27}{\sqrt{n} } <  \mu < 12.33  +   \frac{0.27}{\sqrt{n} } [/tex]

Here notice that the significant figure is keep to three to match the significant figure of the given values

Answer:

[tex]x^3y^5[/tex]

Step-by-step explanation:

[tex]\frac{(x^3y^2)^2(xy^2)}{x^4y} = \frac{(x^6y^4)(xy^2)}{x^4y}=\frac{x^7y^6}{x^4y} =x^3y^5[/tex]

Here , the general rules followed are :-

i) [tex]x^m * x^n =x^m^+^n[/tex]

ii) [tex](x^my^n)^z = (x^m^z)(y^n^z)[/tex]

iii) [tex]\frac{x^my^n} {x^ay^b} = (x^m^-^a)(y^n^-^b)[/tex]

Answer: 5-10x

I really hope this helps you, I tried my best to explain it!

Answer:

Step-by-step explanation:

(x+0)/2 = 4

x + 0 = 8

x = 8

(y+4)/2=6

y+4 = 12

y = 8

Hello your question is incomplete below is the complete question

Let R be a relation from A to B and S a relation from B to C.

(a) Prove that  . [tex]Dom(S \circ R) \subseteq Dom(R)[/tex]

(b) Find a counterexample to show that we don’t always have equality.

answer : (b) Dom ( S o R ) = [ 1 ] and Dom ( R ) = [ 1, ∝ ]

              hence: Dom ( S o R ) ≠ Dom ( R )

Step-by-step explanation:

Note : R ⊆ A * B and  S ⊆ B * C

A) To prove that [tex]Dom(S \circ R) \subseteq Dom(R)[/tex]

 we take note that : S o R ⊆ A x C

ATTACHED BELOW IS THE REMAINING PART OF THE SOLUTION

B) A counterexample to show that we don't always have equality

attached below is a assumptions and solution on how we arrived at the value below

Dom ( S o R ) = [ 1 ] and Dom ( R ) = [ 1, ∝ ]

hence: Dom ( S o R ) ≠ Dom ( R )

Step-by-step explanation:

perp. 3/2

y - 2 = 3/2(x - 2)

y - 2 = 3/2x - 3

y = 3/2x - 1

Answer: $372

Step-by-step explanation:

Let the original retail price be 'x'

Therefore, using the give information, we can form the following equation:

50/100x = 186

Now, solve for x

50/100x = 186

1/2x = 186

x = 186 * 2

x = 372

The original retail price is $372.

Check:

50/100(372) = 186

1/2(372) = 186

186 = 186

It's an odd function.

Step-by-step explanation:

Answer:

a. f(x) is an odd function.

Step-by-step explanation:

Answer: Less than.

Step-by-step explanation:

[tex]\sqrt{8}[/tex] is less than 4 because [tex]4^{2}[/tex] is 16. And [tex]\sqrt{8} ^{2}[/tex] is 8.

Answer:

The sample is the 728 first run movies released in 2011

Step-by-step explanation:

Because this is a multiplication equation, and we need to find one of the factors, we divide.

So 35/3=y

35/3=11.6666667

or 11.67/11.7

Hope it helps!
