Simplify (-2n - 7n4 + 7n3) - (-2n4 - 6n3 + 6n)

Answers

Final answer:

The simplification of the given algebraic expression is -8n -5n^4 + 13n^3 by combining like terms.

Explanation:

The simplification of (-2n - 7n4 + 7n3) - (-2n4 - 6n3 + 6n) involves combining like terms and subtraction. First, change the signs of each term in the second parentheses due to the negative sign in front of the parentheses. This becomes: -2n - 7n4 + 7n3 + 2n4 + 6n3 - 6n. Now, combine like terms to simplify: (-2n - 6n) + (-7n4 + 2n4) + (7n3 + 6n3). The final answer is -8n -5n4 + 13n3.

Which reason supports the true statement that angle1 and angle8 are supplementary?
m || n with
transversal t

Answers

Because 1 and 8 are on a line and are a linear pair, that makes them supplementary. Linear pair definition is the reason.

Hope this helps!!

Angles 1 and 8 are created by line t intersecting with line m.

Line t is called a transversal line, because it intersects 2 parallel lines.

t divides the straight angle formed by m alone, forming the linear pair of angles (1) and (8), whose sum is 180 °, that is they are supplementary.

Answer: (1) and (8) are linear pairs

Given: E is the midpoint of DF
Prove: 2DE = DF

Answers

E is the midpoint so it's HALF of DF

Since it's half that means DE and EF have the same length.

Therefore DE multiplied by 2 is DF.

Considering DF is the full length.

Answer:

2DE = DF.

Hence Proved.

Step-by-step explanation:

Given : E is the midpoint of DF.

To Prove : 2DE = DF

Proof :

We have given a line DF .

D____________F.

Mid point = E

Mid point : It is that point that divide the line in to two equal parts .

D______E______F.

So, DE = EF.

We can say DE= [tex]\frac{1}{2}DF[/tex].

On multiplying both sides by 2.

2DE = DF.

Hence Proved.

Therefore, 2DE = DF.

Hence Proved.

Find an equation of the circle that satisfies the given conditions:

Endpoints of a diameter are P(-1,3) and Q(7,-7)

Answers

Given the two end of the diameter of the circle, we are able to compute the center of the circle as 0.5*[(-1,3)+(7,-7)]=(3,-2). The radius of the circle is 0.5*sqrt[(-1-7)^2+(3+7)^2]=sqrt(41). Therefore the equation of the circle is (x-3)^2+(y+2)^2=41.

Rita and Tina each make $11 an hour working as cashiers at a supermarket. Last week, Rita worked r hours while Tina worked t hours. Rita also worked overtime hours during the week, for which she was paid an extra $32 flat wage. Which expressions represent the total weekly wages of both Rita and Tina? Rita and Tina's total weekly wages can be represented as 11(r)(t) + 32 (11r + 32) + 11t (11t + 32r) + 11r , 11(r + t) + 32 11(r + t) + 32r 11(rt) + 32 , or 11r + 11t + 32 11rt + 32 11r + 32t + 11

Answers

The cost per hour is $11, at that point, the coefficient of the quantity of hours Rita and Tina had worked. With respect to Rita, she will get an additional $32 level wage for her extra hours. It wont be duplicated any further. Mathematically:

Rita's Total Wages = 11r + 32

Tina's Total Wages = 11t

"Rational numbers are numbers that can be written in fraction form. The numbers are all integers. Irrational numbers are numbers that cannot be written as a fraction. They are non-repeating and nonterminating decimals. For example 6.12385546972578945213666479952145412639854845256987452874526874125874........ Is an irrational number. And 1/6, 2,9, and 3/4 are all rational numbers."

Answers

You have a good response. The only critique I can think of is to reduce the size of that massive decimal number. It doesn't have to be huge as long as it's a random string of digits. For example, e = 2.71828182846... is irrational since it has no pattern in the decimal portion. The decimal portion also goes on forever.

The amount of jen's monthly phone bill is normally distributed with a mean of $76 and a standard deviation of $9. what percent of her phone bills are between $49 and $103

Answers

Final answer:

Approximately 99.73% of Jen's phone bills are between $49 to $103. This is calculated by transforming the prices into z-scores regarding the normal distribution and then checking these z-scores in a standard normal distribution table.

Explanation:

The problem is a question about the normal distribution. Using the properties of a normal distribution, we can solve it as follows:

First, transform the phone bill amounts into z-scores. The z-score is the number of standard deviations from the mean.For $49, the z-score is (49 - 76) / 9 = -3.For $103, the z-score is (103 - 76) / 9 = 3.Next, look up these z-scores in a standard normal distribution table or use a calculator that can calculate areas under the normal distribution.The table or the calculator will give you the percent of all observations falling below these two scores.The area to the left of z = 3 (or to the right of z = -3) is about 99.865%, and the area to the left of z = -3 is about 0.135%. Finally, subtract the percentages to get the percent of phone bills between $49 and $103.This is 99.865% - 0.135% = 99.73%.

In conclusion, about 99.73% of Jen's phone bills are between $49 and $103.

#SPJ3

99.74% of Jen's monthly phone bills are between $49 and $103.

To answer this question, we need to understand the properties of the normal distribution. For a normally distributed variable with a mean (μ) of $76 and a standard deviation (σ) of $9, we can use the Z-score formula:

[tex]Z = \frac{(X - \mu)}{\sigma}[/tex]

We now convert $49 and $103 to Z-scores:

For $49:

[tex]Z = \frac{(49 - 76)}{9} = -3[/tex]

2. For $103:

[tex]Z = \frac{(103 - 76)}{9} = 3[/tex]

Next, we use the Z-table to find the probabilities corresponding to these Z-scores:

For Z = -3, the probability is 0.0013 (or 0.13%)

For Z = 3, the probability is 0.9987 (or 99.87%)

To find the percentage of phone bills between $49 and $103, we subtract these values:

[tex]P(49 < X < 103) = 0.9987 - 0.0013 = 0.9974[/tex]

Finally, converting this to a percentage, we get:

[tex]0.9974 \times 100\% = 99.74\%[/tex]

Therefore, 99.74% of Jen's monthly phone bills are between $49 and $103.

What is 1507 million in standard form?

Answers

1,507,000,000

One billion, five hundred seven million

Answer:

1,507,000,000

Step-by-step explanation:

We are asked to write 1507 million in standard form.

We know that 1 million equals 1,000,000.

To convert 1507 million in standard form, we will multiply 1507 by 1,000,000 as shown below:

[tex]\text{1507 million in standard form}=1507\times 1,000,000[/tex]

[tex]\text{1507 million in standard form}=1,507,000,000[/tex]

Therefore, 1507 million in standard form would be 1,507,000,000.

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains
4

liters of natural oil for every
5

liters of synthetic oil. If
296

liters of natural oil are used, how many liters of Petrolyn oil will be made?

Answers

370 liters The problem states that you can make 5 liters of the synthetic oil for every 4 liters of natural oil. So you simply divide the amount of natural oil you have by 4 and then multiple the result by 5 to get the amount of synthetic oil produced. The formula is V = N/4 * 5 Substituting the known value of 296 for N gives V = 296 / 4 * 5 = 74 * 5 = 370 So you can make 370 liters of Petrolyn oil from 296 liters of natural oil.

Circle K has a diameter of 24 inches. Find the exact length of semicircle HJI. In your final answer, include all of your calculations.

Answers

When you say length, I am assuming you mean the circumference?

First find the circumference: [tex]c = 2\pi\r[/tex]
r = radius = 24/2 = 12
Now plugin 12 for r
[tex]c = 2\pi\r[/tex]
[tex]c = 2\pi12[/tex]
Now solve
[tex]c = 2\pi12[/tex]
Now divide in half
[tex]c = 2\pi12 = 75.398[/tex]
[tex]sim-c = \frac{2\pi12}{2} = 37.6991 [/tex]
OR
[tex]sim-c = \frac{75.398}{2} = 37.6991 [/tex]

Answer:

12 π inches

Step-by-step explanation:

1) Since semicircles = 180 degrees, semicircle HJI = 180 degrees.

2) Make a ratio: 180/360. Simplify it: 1/2.

3) Then do: 1/2 x π d --> 1/2 x π 24. You should get: 12 π.

4) So, the exact length of semicircle HJI = 12 π inches.

(The reason you are supposed to leave it 12 π centimeters is because only if the question asks you to find the approximate length of the arc, then you can use 3.14 instead of π. But if the question asks you to find the exact length of the arc, you have to leave it as said above because you would still have to round the answer (if you multiply 12 by pi), which makes it an approximate answer, not an exact answer.)

pi (π) = 3.14159265359......................

Pi is an endless number.

What is the length of hn¯¯¯¯¯¯ ? segment a n with point h between a and n. congruency markings on segment a h and segment h n. segment a n is labeled as being 38 units long enter your answer in the box?

Answers

the answer is #K12. hope this helps

Answer:

The length of HN is 19 unit.

Step-by-step explanation:

Consider the provided information:

It is given that the length of line segment AN is 38 units.

Now consider figure 1:

It is given that the point H is in between A and N. Also with the concurrency markings on segment AH and segment HN.

Therefore, the length of the segment AH = HN

AH + HN = AN

Consider the length of AH = HN = x

Therefore,

[tex]x+x=38[/tex]

[tex]2x=38[/tex]

[tex]x=\frac{38}{2}[/tex]

[tex]x=19[/tex]

Hence, the length of HN is 19 unit.

now, how do we get the coefficients? well, the first coefficient is 1, any subsequent is " the product of the current terms's coefficient and the exponent of the first element, divided by the exponent of the second element in the next term", now that's a mouthful, but for example,

how did get 210 for the 5th expanded term? well is just 120 * 7 / 4

how about 252 of the 6th term? 210 * 6 / 5.

how about 45 of the 9th one? 120 * 3 / 8.

of course, the exponents for each is simple, as you'd already know from the binomial theorem.

so, just expand away the 9th expanded term.

Given that cosθ = - and θ is in the second quadrant, find cscθ.

Since sin²x+cos²x=1, we can plug (-12/13) for cos(x) to get (-12/13)²+sin²x=1
= 144/169+sin²x=1. Subtracting 144/169 from both sides, we get 25/169=sin²x. Square rooting both sides, we get 5/13 as sinx (since √25=5 and √169=13,as well as that it's in quadrant 2 - if it was in quadrant 3 or 4, it would be -5/13). Since cscx=1/sinx, we can plug (5/13) in for sinx to get 13/5 as our answer
