What type of number is 25,747. whole number, integer, rational or irrational

Answer:

-1

Step-by-step explanation:

To find the slope, we use the formula

m = (y2-y1)/(x2-x1)

   = (5-7)/(-3--5)

   = (5-7)/(-3+5)

   = -2/2

  =-1

How many minutes are in 9 hrs

1 hr = 60 min

You must apply dimensional analysis (aka setting up fractions where the units you want will cancel out and the ones you want stay)

[tex]\frac{9 hr}{1} *\frac{60 min}{1hr}[/tex]

9 hrs is 540 min

Hope this helped!

Answer:

so since there is 60 minutes in 1 hour and 60 is divisible by 10 all you have to do is multiply 6 by 9 and you get 54 but since it's 60 than that changes the answer to 540 since it's divisible by 10

Rational Numbers

Step-by-step explanation:

According to the definition of rational numbers, the numbers which can be written in the form of p/q where p and q belong to the set of integers and q is not equals to zero are called rational numbers i.e 8/9, 9/6, -3/4

So, the answer to given question is:

Answer:

Choice B), [tex]f(x) = -3|x|[/tex].

Step-by-step explanation:

Each point on the graph of [tex]g(x)[/tex] can be represented as [tex](x, g(x))[/tex].

When the graph of [tex]g(x)[/tex] is reflected over the x-axis, each point on the graph is also reflected over the x-axis. The x-coordinate of each point will not change but the sign in front of the y-coordinate will flip. For example, [tex]1[/tex] (same as [tex]+1[/tex]) will become [tex]-1[/tex], and vice versa. In general, [tex](x, g(x))[/tex] will become [tex](x, -g(x))[/tex].

On the other hand, points on the graph of [tex]f(x)[/tex] can be represented as [tex](x, f(x))[/tex]. [tex]f(x)[/tex] is the reflection of [tex]g(x)[/tex], so [tex](x, -g(x))[/tex] and [tex](x, f(x))[/tex] shall be equivalent. In other words,

[tex]f(x) = -g(x) = - 3|x|[/tex].

Answer:

y^3 - 3y^2 + 9y

distribute 3

3y^2 - 9y + 27

add/combine like terms and order correctly

y^3 + (3y^2 - 3y^2) + (9y - 9y) + 27

answer

Answer:

[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

Using the rules of exponents

•  [tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]

• [tex]a^{\frac{m}{n} }[/tex] ⇔ [tex]\sqrt[n]{a^{m} }[/tex]

Hence

[tex]16^{-\frac{3}{4} }[/tex] = [tex]\frac{1}{16^{\frac{3}{4} } }[/tex]

= [tex]\frac{1}{\sqrt[4]{16^{3} } }[/tex] = [tex]\frac{1}{2^{3} }[/tex] = [tex]\frac{1}{8}[/tex]

The simplest basic geometric object is a point. It is named with a capital letter and symbolized by a dot. The correct option is C.

The simplest basic geometric object is a point. It is named with a capital letter and symbolized by a dot. A point has no size and solely represents the position (that is, zero length, zero width, and zero height).

Since a plane is a flat, endlessly long two-dimensional surface. A plane is a two-dimensional analog that can incorporate three dimensions of space, a line, and a point.

Now, the statement that will be true about the three points given is that only one plane can be drawn so it contains all three points.

Hence, the correct option is C.

Answer:

1. 13.98

2. 14.47

Step-by-step explanation:

The question is on sample standard deviation and population standard deviation

Arrange the data in increasing order

12,14, 16,16,17,19,21,26,35,37,42,43,45,46,56

n=15

Find the mean of the data set

[tex]mean = (12+14+ 16+16+17+19+21+26+35+37+42+43+45+46+56)/15[/tex]

mean= 29.67 ⇒30

Find the deviations

You subtract the value of mean from each of  the data set given

Deviations= -18, -16, -14, -14, -13,-11, -9,-4,5,7,12,13,15,16,26

Find squares of deviations

= 324, 256, 196, 196, 169, 121, 81, 16, 25, 49, 144, 196, 225, 256, 676

Find sum of squares of deviations

[tex]324+ 256+ 196+ 196+ 169+ 121+ 81+ 16+ 25+ 49+ 144+ 196+ 225+ 256+ 676 = 2930[/tex]

1. Treating the data set to represent an entire population then;

Variance= sum of squares of deviation/number of data set

Variance= 2930/15 = 195.33

Population standard deviation = √195.33 = 13.98

2. Treating the data set as a sample , the number of data set is reduced by one.i.e n= 15-1= 14

Sample Variance=2930/14 =209.29

sample standard deviation= √209.29 = 14.47

Answer:

Step-by-step explanation:

Nice work with the latex. It is a hard language to use.

Numerator:

take out x(x^2 + 7x + 10)

Factor the contents of the brackets: (x + 2)(x + 5)

Combine x * (x + 2) * (x + 5)

Denominator: Leave at is it is.

Combine

[tex]\dfrac{(x)(x + 2)(x + 5)}{x^4*(x + 2)}[/tex]

Be very careful with this next step. Cancel the x and the (x + 2) in the top and bottom. You are left with

[tex]\dfrac{(x +5)}{x^3}[/tex]

The reason you have to be so careful is that you have to (or you should) mention that these cancellations can take place only if x ≠ 0 or that (x + 2)≠ 0

Answer:

[tex]y=-3x+14[/tex]  or  [tex]3x+y=14[/tex]

Step-by-step explanation:

we have

[tex]y+1=-3(x-5)[/tex] ----> equation of the line into point-slope form

step 1

Convert to slope intercept form

The equation of the line into slope intercept form is equal to

[tex]y=mx+b[/tex]

so

[tex]y+1=-3(x-5)[/tex]

[tex]y+1=-3x+15[/tex]

[tex]y=-3x+15-1[/tex]

[tex]y=-3x+14[/tex] ----> equation of the line into slope intercept form

step 2

Convert to standard form

The equation of the line into standard form is equal to

[tex]Ax+By=C[/tex]

so

we have

[tex]y=-3x+14[/tex]

Adds 3x both sides

[tex]3x+y=14[/tex] ----> equation of the line in standard form

C) a ≥ 3 + 2j; j ≤ 14, a ≤ 35

D) a ≤ 3 + 2j; j ≤ 14, a ≤ 35

All the system of linear inequalities which can be used to find the possible ages of Anna, a, and Jamie, j are,

a < 3 + 3j

j ≥ 14

a ≤ 35

We have to given that,

Anna is no more than 3 years older than 2 times Jamie’s age.

Jamie is at least 14 and Anna is at most 35.

Let us assume that,

Age of Anna = a

Age of Jamie's = j

Hence, system of linear inequalities which can be used to find the possible ages of Anna, a, and Jamie, j are,

For Anna is no more than 3 years older than 2 times Jamie’s age.

a < 3 + 3j

And, Jamie is at least 14 and Anna is at most 35.

j ≥ 14

a ≤ 35

Thus, All the system of linear inequalities which can be used to find the possible ages of Anna, a, and Jamie, j are,

a < 3 + 3j

Answer:

y+3=-6(x +9)

Step-by-step explanation:

equation represents a line that passes through (-9, -3) and has a slope of -6is:

y+3=-6(x +9)

because : The equation of a linear function in point-slope form is:                    y – y1 = m(x – x1) ....m : the slope

The point is A (x1 , y1)

you have m = - 6      x1 = -9      y1 = -3

The equation represents a line that passes through (-9, -3) and has a slope of -6 is y+3 = -6(x+9).

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, a line is passing through the point (-9, -3) and the slope of -6,

We need to determine the equation of the line,

The general formula of a line passing through a point (x', y') and have slope m is given by,

y-y' = m(x-x')

Here, (x', y') = (-9, -3), m = -6,

Therefore, the equation of the asked will be =

y-(-3) = -6(x-(-9))

y+3 = -6(x+9)

Hence, the equation represents a line that passes through (-9, -3) and has a slope of -6 is y+3 = -6(x+9)
