Answer:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection)

is 2.346982105 an irracional number?
Answer:
Step-by-step explanation:
Yes. because In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers
Answer:
yes
Step-by-step explanation:
Irrational numbers are numbers that simply are not rational, and cannot be written as a fraction, though they cna be written as a decimal. Irrational numbers msot of the time have a lnog row of non-repeating numbers after the decimal. So, yes.
2.346982105 is an irracional number

Step-by-step explanation:
Yes that is definitely possible. You will have to either double up on geometry and algebra II or algebra II and pre-calculus. At my high school, there were multiple people that did the latter. I also knew someone that doubled up on pre-calculus and calculus I, but I don't recommend that.
Solve:

Full working out please
Also does X have to be on the Left side always?
Answer:
x > -3.4
Step-by-step explanation:
1 < (x + 5.5) / 2
first multiply each side by 2
2 < x + 5.5
Then subtract 5.5 from each side
-3.4 < x
x has to be on the left so you switch the hole equation around to get
x > -3.4
Line l is the perpendicular bisector of segments ps. Unfortunately, s got lost
Mark point s
The perpendicular bisector of a line divides the line into two equal segments and is perpendicular to the line
The perpendicular distance of point P from the line l is equal to the distance of the lost point s from the line l and points P and s are on opposite sides of the line l
The point s can be marked by constructing the perpendicular to line l passing through P
The steps to construct a perpendicular line from a point to a line and mark point s are given as follows;
Place the compass at the point P, and draw an arc intersecting line l at two points, A and BPlace the compass at point A and draw an arc with a radius, r, larger than half the length of segment AB above and below line lPlace the compass point at point B, and with the same radius r draw arcs intersecting the the arcs drawn from point A above and below the lineMark the point of intersection of the two arcs above and below the line l as the points D and EJoin points D and E with the a line to form the line DE drawn with a straightedge and extend DE line such that it passes through point PMark the point of intersection of the line DE and line l as the point F on the line lPlace the compass at the point F, and with a radius FP, draw an arc to intersect the line DE on the other side of the line lMark the point of intersection of the line DE by the arc of radius FP as the point sThe constructed point s above is the required point and points P and s are located on opposite sides of the line l

1. Beth works at the mall for $12.75 per
hour. She works for 41 hours per day on
2 days each week. How much does she
make in 2 weeks? (before taxes)?
Answer:
$2091
Step-by-step explanation:
We know:
12.75 per hour (h)
41 hours each day twice a week: each week (41 x 2) = 82
Since it is asking for two weeks: 82 x 2 = 164 hours
164 x 12.75 = $2091

On average, a person’s heart beats about 4.2×107 times per year. There are about 7,600,000,000 people in the world. Use this data to approximate the number of heartbeats for all the people in the world per year. Expressing your answer in scientific notation in the form a×10 b , what are the values of a and b ?
A person heart beats is 4.2 x 10∧7
there are 7,600,000,000= 7.6 x 10∧9
the heartbeats for all the people here on earth= 4.2 x 10∧7 x 7.6 x 10∧9
choosing like terms
4.2 ×7.6×10∧7×10∧9
31.92x10∧(7+9)
31.92×10∧16
a=31.92
b=16
Answer:
[tex]3.192*10^1^7[/tex]
Step-by-step explanation:
To find this value, multiply the two values given:
4.2x10^7 = 4.2 x ( 10 x 10 x 10 x 10 x 10 x 10 x 10) = 42000000
42000000 x 7600000000 = 319200000000000000
Then convert 319200000000000000 into scientific notation:
319200000000000000 = 3.19200000000000000
Cut off all the zeroes and I moved the decimal 17 places to the left, so the exponent will be positive:
[tex]3.192*10^1^7[/tex]

!!I WILL MARK BRAINEST!! number 6 please. i did the question but i’m not sure if i even got the answer correct. please help me, thank you!
Step-by-step explanation:
If everything is kept in terms of x then:
For part A the general area would just be side times side.
Here it would be (30x)(4x)
=[tex]120x^{2}[/tex]
For part B since you have 5 sections divide the long side by 5.
[tex]\frac{30x}{5} =6x[/tex]
Then multiply by the other side of the rectangle to find the area of one section.
6x(4x)=[tex]24x^{2}[/tex]
Alternatively you could just divide the large area by 5 to get the area of one section.
[tex]\frac{120x^{2} }{5}=24x^{2}[/tex]

Richard tosses a ball into the altThe function b(t) = - 5t ^ 2 + 10t + 6 the the ball itDoes the a height of 12 m?
Answer:Nope
Step-by-step explanation:
The equation, b(t) = - 5t ^ 2 + 10t + 6, is a parabola with a vertex. We must find whether that vertex is equal to or exceeds 12m. One can graph the equation and find that the vertex is at (1,11), below the 12. It cannot reach 12 meters.
[One may also differentiate the equation and set it equal to zero (the point at which the slope of the parabola is zero, which will be at the vertex as it begins downward)].

A flash disk has the capacity of storing 1 megabyte of data. How many kilobytes of data can be stored in the same flash disk
For this sort of problem, you need to be familiar with prefixes.
So:
megabyte = [tex]1 *10^6[/tex] bytes
kilobyte = [tex]1*10^3[/tex] bytes
and a regular byte would just be [tex]1[/tex]
Now, you will need to do a conversion:
[tex]1megabyte*\frac{1*10^6bytes}{1megabyte}*\frac{1*10^{-3}kilobyte}{1byte}[/tex]
I'm going to explain this just in case, but we convert megabytes to regular bytes in the first half by using the information I gave you above. (In one megabyte, there are [tex]1*10^6[/tex] bytes!)
In the second fraction thought, remember one kilobyte is [tex]1*10^3[/tex] bytes. However, you usually only see one of each thing on the bottom of fractions, so you need to add a negative sign to the 3. (technically you could just do [tex]\frac{1kilobyte}{1*10^3bytes}[/tex], but I think it is more correct to do write it out how I did).
*** They do equal the same thing though! Do whichever way is easier for you!
Now, your answer should be:
[tex]10^3[/tex] kilobytes (1000 kilobytes)

The formula for converting from Celsius to Fahrenheit is F=9/5C+32. The Fahrenheit temperature of a certain city has never exceeded 86 degrees. How would you describe this using Celsius temperature?
Answer:
The temperature in Celsius in this city has never exceeded 30 °C
Step-by-step explanation:
Just substitute F by the temperature in Fahrenheit and solve the equation:
86 = 9C/5+32 Multiply both sides by 5
5×86 = 9C +32×5
430 = 9C + 160 Subtract 160 in both sides
270 = 9C Divide both sides by 9
30 = C

Step-by-step explanation: y=mx+b . formula
3 4. What is the slope of the line that passes through (-2, 1) and (8,5)?
Answer: 2/5
Explanation: Ask if you want an explanation!
The question gives us two points, (-2, 1) and (8,5), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (5 - 1) ÷ (8 - (-2))
= ⁴/₁₀
= ²/₅
Checking my answer:
We can check to see if the answer is correct by drawing the line and seeing if it passes through both points. If it does, then the slope is correct.
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 1 = ²/₅ (x + 2)
In the graph below (created using Desmos), the line passes through both points. This suggests that we calculated the slope correctly.
