Answer:
the image is congruent with the original, angles and lengths are unchanged
Step-by-step explanation:
Translation, rotation, and reflection are known as "rigid transformations". Effectively, you can cut the figure from some rigid material, and move it according to any of these transformations without causing it to deform in any way.
All lengths and angles retain their measures when the figure is rotated about any point, through any angle. The rotated figure is congruent with the original.

Step by Step What do I do
Answer:
7:46
Step-by-step explanation:
The clock says 9:20. I am assuming that the question is related to the clock on the left. It asks for the time an hour and 34 minutes ago. One hour from 9:20 is 8:20. Now we work with the minutes. 8:20 minus 34 minutes is 7:46.

How can you estimaite [tex]\sqrt 40.[/tex]
9514 1404 393
Answer:
√40 ≈ 6 4/13 ≈ 6.31
Step-by-step explanation:
The estimate by linear approximation starts with the recognition that ...
40 = 36 +4 = 6² +4
and the difference from 36 to the next square, 7² = 49 is 49-36 = 13.
The linear approximation to √40 is ...
√40 ≈ 6 4/13 ≈ 6.31
__
There are various methods for improving this approximation. Perhaps the fastest improvement is obtained using the "Babylonian method." The next iteration is the average of this value and 40 divided by this value.
(82/13 +40/(82/13))/2 = 6 173/533 ≈ 6.3246 . . . . accurate to 4 decimal places
_____
Additional comment
When you write the value in terms of a square and a remainder:
n = s² +r
then the above linear approximation of √n can be written as ...
√n ≈ s +r/(2s+1)
Using the idea that a square root can always be represented by a continued fraction, we can continue the fraction one more iteration to give a slightly better approximation:
√n ≈ s +r(2s+1)/(2s(2s+1) +r)
For the case at hand, this gives √40 ≈ 6+52/160 = 6 13/40 = 6.325, accurate to 3 decimal places. Additional iterations using the continued fraction idea can be had using ...
n'' = s + r/(s +n') . . . . . where n' is an approximation of the root and n'' is a better approximation. This does not converge as fast as the Babylonian method, but may be easier to calculate on some calculators.
Find the slope- intercept form -5x+6y=30
Please show steps
Answer:
slope-intercept is 5/6x, y intercept is 5 and x intercept is -6
Step-by-step explanation:
-5x+6y=30
first you are going to move your thirty to the other side of the equation so your going to minus 30 from both sides.
-5x+6y(-30)= 30(-30)
-5x+6y-30=0
then move your y to the other side of the equation
-5x-30=6y
divide by 6 to get y alone
-5/6x -(30/6)=y
-5/6x-5=y
therefore your slope is 5/6x, your y intercept is 5 and your x intercept is -6

Answer:
the function is odd
Step-by-step explanation:
functions that are symmetric with respect to the y axis are even functions
functions that are symmetric with respect to the origin (the 0,0 point) are odd functions (which means that if you flipped it 180 degrees it will still look the same)

(2) Below is the graph of a function, y = f (x).
(a) Draw a secant line on the graph above from x = 0 to x = 4. (copy the graph if you are writing your answers on a separate paper)
(b) What is the average rate of change of f (x) from x = 0 to x = 4? Show how you get your answer.
Answer:
Step-by-step explanation:
a. To draw a secant line, just draw a straight line connecting the 2 points at x = 0 and x = 4.
b. The average rate of change of this line is going to be the change in y / the change in x. The equation will be (f(4) - f(0))/(4 - 0) = (0 - 3) / 4 = -3/4.

1hr=220÷8
1hr=22.5
According to the question,
The worker makes,
[tex]8 \ hours = 220[/tex]then,
Per hour, worker will make,
→ [tex]1 \ hour = \frac{220}{8}[/tex]
By applying division, we get

Which is the most reasonable measure of central tendency for the data set?
mean
mode
range
median
Answer:
I think its range I dont know
Step-by-step explanation:
The mean is the maximum often used as a degree of critical tendency because it makes use of all values inside the information set to give you an average. For statistics from skewed distributions, the median is higher than the implied because it isn't motivated through extremely big values.
The correct option is A.
Which is a better measure of center mean or median?The median is normally a better degree than the middle whilst there are intense values or outliers because it isn't always stricken by the right numerical values of the outliers. The suggestion is the maximum common measure of the middle. The phrases “mean” and “common” are regularly used interchangeably.

Dekalbs current population is 3,500 and it is increasing by 40 people pr year. Sycamores current population is 12,040 and it is decreasing by 100 people every year
Q: Write expressions for each population if x represents the number of years
And What is the current population of dekalb?
Answer:
Dekalb: 3500+40x = F
Sycamores : 12,040 - 100x = F
Step-by-step explanation:
These expressions can be used to explain each population
X = number of years for both expression
F = Final population
Dekalb: 3500+40x = F
Sycamores : 12,040 - 100x = F
The current population if 3500 if no years have gone by, plug in the year of numbers for X to find final population after the amount of years.

Show that x is not the factor of 2x*3-x*2-2x+1
Answer:
See explanation
Step-by-step explanation:
If we have a polynomial in x with x as a factor, we know that there will be no constant term. This arises because every term will be a multiple of x, and thus there will be know constant term.
Because there is a constant term in our polynomial, namely 1, x is not a factor of [tex]2x^3-x^2-2x+1[/tex], as desired.
Answer: You divide using polynomial long division or synthetic division and if the remainder is 0 then it is a factor.
