Step-by-step explanation:

So we have the expression:

[tex]\sqrt{125a^2b^2}[/tex]

This is the same as:

[tex]=\sqrt{(5ab)^2\cdot5}[/tex]

Expand:

[tex]=\sqrt{(5ab)^2}\cdot\sqrt5[/tex]

The left term cancels:

[tex]=5|ab|\sqrt5[/tex]

Note that we need the absolute value bars because if a and/or b was negative in the original equation, they will turn positive. Thus, to keep things consistent, we must use the absolute value to make sure that a and b stays negative :)

Answer:

18.00 because 1 pound is 5.00, 1 plus 2 is 3 so 5 x 3 = 18

Step-by-step explanation:

6 pounds of a trail mix contains 2 more pounds of raisin than almonds

i.e.

Suppose:

6 pounds of trails will contain a pound of almond (a) and two more pounds of raisin i.e. (a +2)

∴

a + (a+2) = 6

2a + 2 = 6

2a = 6 -2

2a = 4

a = 2

It implies that there are:

= (a +2) pounds of raisins

= (2+2) pounds of raisins

= 4 pounds of rasins

Provided that:

∴

The total cost of the 6 pounds of trails mix will be:

= 2($4.00) + 2($5.00)

= $8.00 +$10.00

= $18.00

Therefore, we can conclude that the total cost of 6 pounds of trail mix is $18.00

Answer:

Diagram B

Step-by-step explanation:

This is because the line only goes through two points and many are dispered from the line, however diagram A and C have points fairly close to them

Visually inspecting the three scatterplots, the line of best fit does not accurately fit the points on the second graph. Hence, line of best fit should not have been drawn for the second graph as the relationship isn't linear.

The line of best fit minimizes the sum of the square of the mean distance between each point. Hence, the distance between the line and the best fit line should be as small as possible.

However, the second graph isn't linear, hence , a linear line cannot model the relationship.

The main table is at the top. This is what it would look like if you filled out your blank boxes. The second section below shows scratch work to help form the more complicated columns.

=========================================================

Explanation:

We have two atomic variables p and q. They can each take on values of True (T) or False (F).

There are 2*2 = 4 combinations of T and F as shown below

That takes care of the first two columns of the table. Note how there aren't any other ways to have two truth values together.

The third column ~q is where we flip everything in the q column. So if q is true, then ~q is false, and vice versa. A similar situation happens with the ~p column as well.

The ~p v q column is where we apply a disjunction to ~p with q. The V stands for "or". It means either ~p is true or q is true. If either are true, then (~p v q) is true. Otherwise it's false. Put another way, (~p v q) is only false when both ~p and q are false together.

The last column is the entire expression ~q ^ (~p v q). We apply a conjunction to the ~q column and the (~p v q) column. Both expressions must be true for the entire ~q ^ (~p v q) to be true, otherwise it's false.

Let me know if you have any questions. It's probably tricky to wrap your head around at first, but hopefully the table clears things up.

The scratch work section is to show how the fifth and sixth columns are formed.

Answer:

[tex]375001[/tex] police officers

Step-by-step explanation:

[tex]\frac{30,000}{25,000} = \frac{30}{25} = \frac{120}{100} = 1.2[/tex]

That's a 20% increase.

So increase the police by 20% gets you:

[tex]312500 * 1.2 = 375000[/tex]

Based on the wording of the question, if you want a greater percentage, the answer should be a single policeman more, thus 375,001.

Answer:

4/5

Step-by-step explanation:

80% is equivalent to 80/100

80/100 can be simplified into 8/10 by dividing both sides by 10

8/10 can be further simplified into 4/5 by dividing both sides by 2

4/5 can not be simplified any further

Answer:

To make equivalent fractions, what we have to do is multiplicate or divide the numerator or denominator by the same number.

In our case:

[tex]\frac{2}{5}=\frac{2*2}{5*2}=\frac{4}{10}[/tex]

[tex]\frac{2}{5}=\frac{2*6}{5*6}=\frac{12}{30}[/tex]

[tex]\frac{2}{5} = \frac{2*12}{5*12}=\frac{24}{60}[/tex]

That are only three examples, but there are infinite.

We could also obtain equivalent fractions dividing, for example, [tex]\frac{3}{9}[/tex]:

Segment CE is composed of CD and DE, both of which are equal to AB. In other words, AB = CD = DE. Because CD = DE, and the two segments add up to CE, this must mean that CE is twice as long as CD. Therefore, CE is twice as long as AB.

Answer:

A

Step-by-step explanation:

So we have the function:

[tex]f(x)=y=\sqrt[3]{x-2}+8[/tex]

To find the inverse of the function, we can flip x and y and then solve for y. Therefore:

[tex]x=\sqrt[3]{y-2}+8[/tex]

Solve for y to find our inverse.

Subtract 8 from both sides:

[tex]x-8=\sqrt[3]{y-2}[/tex]

Cube each side. The right cancels:

[tex](x-8)^3=y-2[/tex]

Add 2 to both sides:

[tex]y=(x-8)^3+2[/tex]

Answer:

-26

Step-by-step explanation:

Given the sequence:

16, 9, 2, –5, ...,

To find:

7th measurement, if the above sequence continues:

Solution:

Let us examine the given sequence first:

First term is 16

Second term = 9

Third term = 2

Fourth term = -5

Difference between 2nd and 1st term = 9 - 16 = -7

Difference between 3rd and 2nd term = 2 - 9 = -7

Difference between 4th and 3rd term = -5 - 2 = -7

We can see that there is a common difference of -7 between each term.

That means, the sequence is in Arithmetic Progression.

whose first term, [tex]a=16[/tex]

Common difference, [tex]d=-7[/tex]

To find:

7th term i.e. [tex]a_7=?[/tex]

Solution:

Formula for [tex]nth[/tex] term of an Arithmetic Progression is given as:

[tex]a_n=a+(n-1)d[/tex]

Let us put [tex]n=7[/tex]

[tex]a_7=16+(7-1)\times (-7)\\\Rightarrow a_7=16+6\times (-7)\\\Rightarrow a_7=16-42\\\Rightarrow \bold{a_7=-26}[/tex]

7th measurement will be -26.

Answer:

7th measurement= -26

Step-by-step explanation:

The sequence is 16, 9, 2, –5, ...,

First term( a)= 16

Second term=9

Common difference (d) = 9-16

Common difference= -7

The sequence is a arithmetic progression

For AP's ,the terms formula is

Term(n) = a + (n-1)d

Where n represent the term to be found

In this case,we Are looking for the 7th term , so n= 7

Term(7) = 16+ (7-1)-7

Term(7)= 16 +6(-7).

Term (7) = 16-42

Term(7) = -26

7th term =-26

Answer:

26

Step-by-step explanation:

The mean of a set of number is the average the set of number, it is the ratio of the total sum of the terms to the sum of terms.

The standard deviation is the variation of a set of numbers to their mean. A low standard deviation means the value are close to the mean and a high standard deviation means the values are far from the mean. The standard deviation is given as:

[tex]\sigma=\sqrt{\frac{\Sigma (x_i-\mu)^2}{n} }\\ \\\mu=mean,n=number\ of\ terms, \sigma=standard\ deviation[/tex]

Given the numbers:

86, 81, 87, 82. mean = μ = 84

[tex]\Sigma(x_i-\mu)^2=(86-84)^2+(81-84)^2+(87-84)^2+(82-84)^2=4+9+9+4=26[/tex]

Sum of squared deviations = 26

The sum of the squared deviations of the scores from the mean is 26.

-----------------------

Thus:

[tex]S_{ds} = (86-84)^2 + (81-84)^2 + (87-84)^2 + (82-84)^2 = 4 + 9 + 9 + 4 = 26[/tex]

The sum of the squared deviations of the scores from the mean is 26.

Answer:

(3x + 1)²

Step-by-step explanation:

Given

9x² + 6x + 1 ← is a perfect square of the form

(ax + b)² = a²x² + 2abx +  b²

Compare like terms to find a and b

a²x² = 9x² ⇒ a² = 9 ⇒ a = [tex]\sqrt{9}[/tex] = 3

b² = 1 ⇒ b = [tex]\sqrt{1}[/tex] = 1

and 2ab = 2 × 3 × 1 = 6

Thus

9x² + 6x + 1 = (3x + 1)²

Answer:

(3x + 1)^2

Step-by-step explanation:

The first and last terms are perfect squares. From its structure, this is a perfect square trinomial.

All of the symbols in the expression 9x2 + 6x + 1 are positive, so use the rule for the square of the sum of two terms.

In the given expression, a2 = 9x2 and b2 = 1, so a = 3x and b = 1.

2ab = 2(3x)

       = 6x

This result matches the middle term in the polynomial expression, 6x, so apply the rule for the square of the sum of two terms.

The expression 9x2 + 6x + 1 is equal to (3x + 1)2.
