What is equivalent to the polynomial (4x+3)(3x-8)

Mathematics 18/01/2020 12:17 PM
The equivalent polynomial is 12x^2 -23x - 24.

You can get this by multiplying the two parenthesis by each other.

 First start by multiplying the two front numbers:
4x * 3x = 12x^2

Then multiply the outermost numbers:
4x * -8 = -32x

Then multiply the innermost numbers:
3x * 3 = 9x

Then multiply the last numbers: 
3* -8 = -24

Now combine all of them to get the above polynomial. 

Solve (x + 1 < 4) ∩ (x - 8 > -7). {x | 1 < x < 3} {x | x < 3 or x > 1} {all real numbers}

Mathematics 18/01/2020 12:17 PM
When solved 
(x + 1 < 4) ∩ (x - 8 > -7) 
becomes:
(x+1-1 < 4-1) ∩ (x - 8 +8 >  -7+8 ) 
(x < 3) ∩ (x > 1).
and if you change places it will become even more obvious:
 ( 1<x ) ∩ ( x < 3 )
meaning:  x is set of all numbers greater than 1 and less than 3 or otherwise: 
{x | 1 < x < 3}

Help me please.........

Mathematics 18/01/2020 12:17 PM
The 2 red lines on the triangle mean that the 2 sides are equal.

Because the 2 sides are equal, Angle D is the same as angle C.

So now angle C & D are both 52 degrees, we can find Angle E

180 - 52 - 52 = 76 degrees

Angle DEF + Angle E need to equal 180 degrees

Angle DEF = 180 - 76 = 104 degrees

Which of the following means "the general willingness of businesses to make and sell a specific quantity of a product at various prices"? supply demand quantity supplied quantity demanded

Social studies 18/01/2020 12:17 PM

Answer: Supply

Explanation:

Thus, producers tend to produce and supply more goods and services as prices go higher in order to get more profits and revenue.

Write the equation in standard form then factor the left side of the equation 2x'2+7x=15

Mathematics 18/01/2020 12:17 PM
The equation in standard form should be 2x^2 + 7x - 15 = 0

Factored the expression is (2x - 3)(x + 5).

In order to find the factored portion, you must look for factors of the front number (2) to use in the front of the parenthesis and factors of the last number (-15) to go in the end. 

When we use the ones that we have above, it distributes to the overall end result. 

(2x - 3)(x + 5)
2x^2 - 3x + 10x - 15
2x^2 + 7x - 15

Joe buys a set of books that cost $45.58. He gives the cashier three (3) $20 bills and three (3) pennies. How much change should Joe get back?

Mathematics 18/01/2020 12:17 PM
Joe should get $14.45 back. 

This is because you must subtract the total cost from the total amount given. If we add the 3 $20 bills together, we get $60. Then is we add the 3 pennies together we get .03. If we add those two both together we get a total of $60.03.

Now we must subtract the cost given from the overall dollar given: 

60.03 - 45.58 = 14.45 

John has two sisters and two brothers. Three of the five children in the family have dark brown hair, one has red hair, and one has light brown hair. The variation in hair color is due to the input of multiple genes. What pattern of inheritance is exhibited here?

Biology 18/01/2020 12:17 PM
Polygenetic inheritance
This type of inheritance is controlled by a group of epi-static genes which regulate expression of one phenotypic trait, which is hair color in this case. Such genes are often large in quantity but small in effect. These genes could also be pleiotropic as well. Polygenes also exist in other organisms apart from humans. 

I don’t know what to do here

Mathematics 18/01/2020 12:17 PM
The answer is CD = √3

This is because of the fact that a 30-60-90 right triangle has proportions of 1-√3-2 based on the length opposite of the angle. Since we are given the segment opposite to the right angle as 2, we know that we can use the base numbers for the proportions to find the rest. Since CD is opposite of the 60 degree angle, it must be √3.

In a paragraph of 125 words, write a sample response to this behavioral interview question: Describe a team project in which you were not the leader. Evaluate the strengths and weaknesses of the leader. Suggest one thing you would have done differently.

Business 18/01/2020 12:17 PM
In the 10th grade, I was teamed up in a group of four. Our project was on Modern History. Altho it seemed super hard for many of us. Patrick Fleming took charge and showed us the understanding of this project.  His leadership showed great ethics and it taught me, personally, how to help others understand, not just to show them, but explain it thoroughly. And altho he was a great teacher I would have changed a few things. One being his attitude. Many times he would get frustrated and impatient with the group.  I think a leader I would have done exactly what he did but with much more patience and be there more to explain. Such as lunch learning. And giving everybody a chance to try to explain it in their head.
