Question 4:

A.) Documentation Files (Field Reports)

Explanation:

Archaeologists record their findings in documentation files or field reports because that would be the more formal and official to jot down important information.

Question 5:

B.) Information Collection and Review

Explanation:

Archaeologists verify existing archaeological records through the information collection and review stage. This one was a tricky question, because it's asking about existing records, not newly found records.

Answer:

16

Step-by-step explanation:

3 times 16 is 48

hope this helps :)

Final answer:

The value that will not make the inequality 3x < 45 true is 16, as any value greater than or equal to 15 does not satisfy the inequality.

Explanation:

To determine which values will not make the inequality 3x < 45 true, we first solve the inequality for x by dividing both sides by 3.

Dividing 45 by 3 gives us:

45 / 3 = 15

So the inequality becomes:

< 15

Any value for x that is 15 or greater will not satisfy the inequality. Looking at the provided options (12, 11, 16, -8), the number 16 is the only value that is greater than 15, and hence, will not make the inequality true.

Answer:

Step-by-step explanation:

If f(x)=x²

g(x) = (3x)²

because : g(0)=0 and g(1)= (3×1)² =3 passes  through A(1;3) and O(0;0).

Answer: g(x) = 3x²

Step-by-step explanation:

Since we have given that

[tex]f(x)=x^2[/tex]

So, the function of g(x) would be

[tex]g(x)=ax^2[/tex]

since we have given that

(1,3) on g(x means (x,ax)

Here, x = 1.

So, ax = 3

which implies that a = 3.

So, g(x) would look like

[tex]g(x)=3x^2[/tex]

and the graph of g(x) is compressed.

The slope of a line perpendicular to another is the negative reciprocal of the other line.

In this case, the slope of this line is just 0. It'll be better to think of it as instead of 0, something like 0/1, or 0/2, which are equivalent to 0 but work better with the explanation. I'm just going to use 0/1

Therefore, when you take the negative reciprocal of the slope of 0/1, then you end up with -1/0 as the slope of line n. When you divide by 0, the answer is always undefined. Therefore, the line has an undefined slope.

Another way to think about this is by thinking of Line m as a horizontal line. A line with a slope of 0 is just a horizontal line. Perpendicular lines are lines that meet at 90 degree angles. Therefore, the line that would meet with line m, line n, would be a vertical line. And since vertical lines have an undefined slope, line n would have an undefined slope.

Answer:

B. The mean study time of students in Class B is less than students in Class A.

Step-by-step explanation:

First step is to calculate the mean and median for both classes.

Class A: 2, 5, 7, 6, 4, 3, 8, 7, 4, 5, 7, 6, 3, 5, 4, 2, 4, 6, 3, 5

sorted data set: 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 6, 6, 6, 7, 7, 7, 8

total: 96

# of students: 20

Mean/average: 96 / 20 = 4.8

Median: By looking at the sorted data set, we see that the 10th value is the first 5, so median = 5

Class B: 3, 7, 6, 4, 3, 2, 4, 5, 6, 7, 2, 2, 2, 3, 4, 5, 2, 2, 5, 6

Sorted data set: 2, 2, 2, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7

Total: 80

# students: 20

Mean/average: 80 / 20 = 4

Median: By looking at the sorted data set, we see that the 10th value is the first 4, so median = 4

So, we can see that the mean study time for group B was less than the students of class A.  Answer B.

Final answer:

To calculate the area of a circle with a circumference of 31.4 units, first find the radius using the formula r = C / (2π), then use the area formula A = πr² to obtain an area of 78.5 square units when π is approximated to 3.14.

Explanation:

To find the area of a circle with a given circumference, we first need to find the radius of the circle. The formula to calculate the circumference (C) is C = 2πr, where r is the radius and π (pi) is approximately 3.14159. For a circle with a circumference of 31.4 units, we can rearrange the formula to solve for the radius: r = C / (2π). Substituting the given circumference, we have r = 31.4 / (2×3.14) which simplifies to r = 5 units.

Now, we can find the area (A) of the circle using the formula A = πr². Substituting the calculated radius, the area becomes A = 3.14×5² which equals A = 3.14×25. Therefore, the area of the circle is A = 78.5 square units.

This calculation assumes the value of π (pi) is rounded to 3.14 for ease of calculation, which is typically 'close enough' for most estimation purposes.

Answer:  [tex]h=8[/tex]

Step-by-step explanation:

To find the value of "h" you need to:

Remember the multiplication of signs:

[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-[/tex]

Distribute the positive sign that is outside the parentheses to  eliminate the parentheses:

[tex]4h + 9 = 3 -h + 46[/tex]

Add like terms on the righ side of the equation:

 [tex]4h + 9 = -h + 49[/tex]

Add h to both sides:

[tex]4h + 9+h = -h + 49+h[/tex]

[tex]5h + 9 =49[/tex]

Subtract 9 from both sides:

[tex]5h + 9-9=49-9[/tex]

[tex]5h =40[/tex]

Divide both sides by 5:

[tex]\frac{5h}{5}=\frac{40}{5}\\\\h=8[/tex]

Answer:

Explanation:

There are many types of symmetry presented at school time. Many of the symmetry we used during photo shop. The simple picture can be symmetrical by putting a mirror seeing an image in the mirror.

There has been seen half of the original image and half of the mirror reflection. It can be said that the original picture is symmetric with the help of the mirror. It is also called reflective symmetry.

The mirror symmetry also called a one-line symmetry. The horizontal line of symmetry cuts the picture in two left and right parts.

Answer:

One solution

Step-by-step explanation:

Expanding the equation, we get

-2w-12-6w=4w+12

Subtracting 4w from both sides, we get

-12w-12=12

Now adding 12 to both sides,

-12w=24

Solving for w, we get

w=-2

So there is only one solution to the equation.

The slope is [tex]\frac{3}{4}[/tex] and x-intercept is [tex]\frac{8}{3}[/tex] and y-intercept is -2 of the linear equation [tex]y=\frac{3}{4}x-2[/tex].

Slope intercept form is one of the forms used to calculate the equation of a straight line.

i.e. y = mx + b

Here, m= slope and y = intercept ,

We have,

[tex]y=\frac{3}{4}x-2[/tex]

Now,

Compare the given equation with the slope intercept form,

i.e.

y = mx + b

[tex]y=\frac{3}{4}x-2[/tex],

So,

Slope [tex](m)=\frac{3}{4}[/tex],

Now,

To know, the x-intercept,

put y = 0,

i.e.

[tex]0=\frac{3}{4}x-2[/tex]

⇒[tex]\frac{3}{4}x=2[/tex]

We get,

[tex]x=\frac{8}{3}[/tex],

Now,

To know, the y-intercept,

put x = 0,

i.e.

[tex]y=\frac{3}{4}*0-2[/tex]

We get,

y = -2

Hence, we can say that the slope is [tex]\frac{3}{4}[/tex] and x-intercept is [tex]\frac{8}{3}[/tex] and y-intercept is -2 of the linear equation [tex]y=\frac{3}{4}x-2[/tex].

Final answer:

The slope of the equation y = 3/4x - 2 is 3/4, and the y-intercept is -2.

Explanation:

The linear equation given is y = 3/4x - 2. In this equation, the coefficient of x represents the slope and the constant term represents the y-intercept. Therefore, the slope of the line is 3/4 and the y-intercept is -2. The slope indicates that for each unit increase in x, y increases by 3/4, while the y-intercept tells us that when x is 0, the value of y is -2, indicating the point at which the line crosses the y-axis.

Step-by-step explanation:

In order to find out the resulting matrix, we will have to multiply the identity matric and the scalar 3:

The 3x3 identity matrix is:

[tex]\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right][/tex]

Multiplying with scalar 3:

[tex]3\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right][/tex]

The scalar will be multiplied by each element of the matrix.

Multiplying zeros with scalar 3 will give us zero. So the resulting matrix will be:

[tex]\left[\begin{array}{ccc}3*1&0&0\\0&3*1&0\\0&0&3*1\end{array}\right] = \left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right][/tex]

The domain is "all real numbers."

The range is also "all real numbers."

Answer:

Domain of both given functions is the set of real numbers.

Range of both given functions is the set of real numbers.

Step-by-step explanation:

Given functions are

f(x)=5x  

And g(x)= 5x

First, we solve for f(x)

Both function are the same

Therefore , the domain of both function is same and range of both functions is same .

Hence,  the domain of  both functions is the set of real numbers and range of both functions is the set of real numbers.
