the perimeter of a triangle is represented by 3x² +8x-9. Two of its sides are represented by (x²+11x+5) and (-2x²-4x+2) What expression would represented the third side​

Answers

Answer 1

Answer:

The third side has a length of 4x² + x - 16

Step-by-step explanation:

We can solve this by taking the value given for the perimeter, and subtracting the values of the other two sides:

3x² + 8x - 9 - (x² + 11x + 5) - (-2x² - 4x + 2)

= 3x² + 8x - 9 - x² - 11x - 5 + 2x² + 4x - 2

= (3 - 1 + 2)x² + (8 - 11 + 4)x - (9 + 5 + 2)

= 4x² + x - 16

Answer:

m<GKH + m<HKI = 180; m<HKI + m<IKJ = 180 - Angles forming a linear pair sum to 180

m<GKH + m<HKI = m<HKI + m<IKJ - Subsitution

m<GKH = m<IKJ - Algebra

<GKH ≅ <IKJ - Definition of congruence

Step-by-step explanation:

Angles that form a linear pair are supplementary because together they make a straight line. So, they must sum to 180.

In statement 2, m<HKI + m<IKJ replaces 180 degrees. This is allowed because m<HKI + m<IKJ is equivalent to 180 degrees, so it can be substituted.

In statement 3, m<HKI is subtracted from both sides. This is allowed through the property of equality, which is a part of algebra.

The definition of congruency is that two shapes that are equal are congruent. So if m<GKH = m<IKJ, then they must be congruent as well.

The number of positive solutions to this equation is ____
The approximate value of the greatest solution to the equation, rounded to the nearest hundredth, is _____

Answers

Answer:

1 solution

2.88

Step-by-step explanation:

Consider this quadratic equation.

x ^2+ 2x + 7 = 21

Subtract 7 from both sides

x ^2+ 2x + 7 -7= 21-7

x^2+2x = 14

x^2+2x -14 = 0

Factorize

x = -2±√2²-4(-14)/2

x= -2±√4+56/2

x = -2±√60/2

x = -2±7.75/2

x = -2-7.75/2 and -2+7.75/2

x = -9.75/2 and 5.75/2

x = -4.88 and 2.88

Hence there are 1 number of positive solution

A central angle of circle P is angle
The measure of RU is degrees.

Answers

Answer:

Step-by-step explanation:

RU=59 degrees

angle = TPQ

Central angle of circle P is a angle equals to 121° and 73°.

The measure of arc RU is 59 degrees

What is circle?

" A circle is closed two dimensional shape , whose all points on the surface are equidistant from its center."

Definition of arc measure

"In a circle, the degree measure of an arc is equals to the central angle present in the included arc."

According to the question,

∠TPU and ∠UPR are supplementary angles.

Given , ∠UPR = 59°

Therefore,

∠TPU = 180° - 59°

         = 121°

∠TPQ + ∠QPR = 180°

∠QPR = 107°

Therefore ,

∠QPR = 180° - 107°

          = 73°

As per the definition of arc measure, we conclude

The measure of arc RU is equals to 59degrees.

Hence, central angle of circle P is a angle equals to 121° and 73° and

measure of arc RU is 59 degrees.

Exercise 1.6 introduces a study on the relationship between socio-economic class and unethical behavior. As part of this study 129 University of (California Berkeley undergraduates were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. They were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. After completing some unrelated tasks, participants reported the number of candies they had taken. It was found that those who were identified as upper-class took more candy than others.
A. Identify the population of interest and the sample in this study.
B. Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.

Answers

Answer:

(A) Population: UCB undergraduates

Sample: The selected 129 UCB undergraduates

(B) Yes, they can be generalized to the population

No, the findings of this single study cannot be used to establish causal relationships between socio-economic classes and unethical behaviors.

Step-by-step explanation:

STUDY: Relationship between socio-economic class and unethical behavior.

The bases for determining social class here are:  money, education, and respected job.

RESULT: Those who identified as upper class took more candy than others.

(A) Identify the population of interest and the sample, in this study.

The population of interest in this study is UCB undergraduates.

The sample in this study is the 129 UCB undergraduates who were selected and who agreed to take part in the experiment. They were the participants who were divided into the two social classes before the experiment was conducted.

(B) The results of the study can be generalized to the population of UCB undergraduates since it's likely that the results would be same in another group of 129 UCB undergraduates.

The findings or results of the study cannot be used to establish causal relationships unless the study is conducted in more universities and majority of the results are same with this.

I'm not 100% sure, but I do think it is

0.042768

But it is asking for percentage, and says to round 3 decimal places, making it confusing whether you round 0.042768 first, or you round the percentage of 4.2768%. I would argue with your teacher, as the excuse of why this was turned in late.

Step-by-step explanation:

It is either 4.277% or 4.3%.

Yes, you may wonder why the second possibility is just a rounded form of the first answer. It is due to rounding to three decimal places first, as 0.042768 rounded to three places is 0.043 because the 7 is more than 4 blah blah blah kiddy rhymes from elementary school yeah.

That would become 4.3%.

But 0.042768 if you turn it to a percent first is 4.2768% which becomes 4.277% if you round it afterwards. Argue this to a teacher or something.

Let's solve for x.

25x+15y=17

Step 1: Add -15y to both sides.

25x+15y+−15y=17+−15y

25x=−15y+17

Step 2: Divide both sides by 25.

25x/25 = -15y+17/ 25

x equals...

x= -3/5 y + 17/25

Let's solve for x.

25x+15y=305

Step 1: Add -15y to both sides.

25x+15y+−15y=305+−15y

25x=−15y+305

Step 2: Divide both sides by 25.

25zx/25 = -15y305/25

Step-by-step explanation:

If you do 22.50 times 10 you get 225 then you add 6.50 which would give you 231.50. You cant add any more pairs of shoes because you would go over the $250 limit. For example if you added 22.50 one more time you would be at 254. Therefore it would be 10 pairs of shoes.

Given that M is the midpoint of line segment AC, AM = x + 20, and MC = 5x - 4. Find the lenght of AM.

Answers

Answer:

6 units

Step-by-step explanation:

AM = MC

AM = x + 20

MC = 5x - 4

x + 20 = 5x - 4

20 = 4x - 4

24 = 4x

x = 6

The required length of the AM is 27.

Given that,
M is the midpoint of line segment AC,
AM = x + 20, and MC = 5x - 4.
To find the length of AM.

What is the midpoint?

The midpoint is that point the line whose distance from both the ends of the line is equal.

Here,
M is the midpoint of line segment AC, i.e.
AM = AC                             - - - - - - - - - - -- - - (1)
AM = x + 20, and MC = 5x - 4
Put  AM and MC in equation 1

x + 20 = 5x - 4
5x - x = 20 + 4
4x = 24
x = 24 / 4

x = 7

Now,
Length AM =  x + 20
Length AM =  7 + 20
Length AM =  27

Thus, the required length of the AM is 27.

Susie can walk 7 dogs in 2.5 hours.

Meaning that if you add 8 dogs plus 7 dogs, you get 15 dogs.
