PLS help :) Which of the following qualities does not describe a line? Select all that apply.
1.has no width
2.imaginary
3.curved
4.has two endpoints
5.endless
Answer:
Hi there!
Step-by-step explanation:
In my opinion, the answer should be 1 (and maybe 4)
We can tell 1)has no width is the answer because the lines the one dimensional.
So the answer has to be number 1.
And...
Number 4 might also be correct because that would be a line segment (which goes on in both directions)
********************************************
So your answer should be letter 1 (also it might be letter 4 too, but I am not that sure)
Hope this helps!
~Have a great day!~

the inverse of the function graphed blow is a function A. true B. false
Answer:
A
Step-by-step explanation:
true true true true true true
Answer:
False
Step-by-step explanation:
In order to tell if an inverse is a function, you have to do the horizontal line test. Create an imaginary line going horizontally on the map and if the graphed function goes through more than one line, then the inverse won't be a function. There can only be one point going through the imaginary line. Does that make sense?

How do you graph y = √ 5 - x?
Answer:
How to graph y=√5 -x is shown in attachment
Step-by-step explanation:
Answer:
see attached
Step-by-step explanation:
As with any sort of graphing problem, pick values of x and compute the corresponding value of y. Then plot those (x, y) points.
For something like this, it is convenient to choose y and then compute the value of x that goes with it.
y = 0 = √(5 -x) ⇒ x = 5 -0² = 5
y = 1 = √(5 -x) ⇒ x = 5 -1² = 4
y = 2 = √(5 -x) ⇒ x = 5 -2² = 1
y = 3 = √(5 -x) ⇒ x = 5 -3² = -4
Once you have plotted the points, draw a smooth curve through them.
What is the absolute value of Point Clabeled on the number line?
Answer:
2 1/4
Step-by-step explanation:
An absolute value cannot be negative, so the negative answer choices are eliminated. The point labeled C is 5 tick marks to the right of 1. We know from the other numbers on the line that 4 tick marks constitutes one unit, so C is 5/4 = 1 1/4 units to the right of 1. Its value is 2 1/4.
What is the factors of 5.1x
Answer:
1, 5.1, x, 5.1x
Step-by-step explanation:
5.1x can be split into 5.1 * x, therefore, we know that two of the factors are 5.1 and x. Keep in mind that 2 factors of a number are always 1 and the number itself, so we know that 1 and 5.1x are also factors. The final answer is 1, 5.1, x, 5.1x.
how to move a parallel line next to the origin
Answer:
Write its y-intercept as zero:
[tex]y=m\,x[/tex]
Step-by-step explanation:
If the line is given in slope-intercept form:
[tex]y=m\,x+b[/tex]
make sure that you keep the value of the slope (m) as it is (because you want a line parallel to this one so it has to have the same slope "m", and change the value of "b" to zero, leaving the line with the following form:
[tex]y=m\,x+0\\y=m\,x[/tex]
This forces the line to have its y-intercept at the value zero (origin of coordinates)
The total cost to repair Deborah's computer is repersented by0.08(50h)+50h, where h represents the number of hours it takes to repair the cmputer. What part of the expression repesents the amount of tax Deborah has to pay. Explain
Answer:
0.08(50h)
Step-by-step explanation:
The amount of tax payable over a particular object or goods is always represented as a particular percentage of the total cost of buying or repairing an object.
From the above question we are given the expression,
0.08(50h) + 50h = Total amount Deborah is paying to repair her computer
Note that: Total amount payable by Deborah = Cost (Price or amount) of fixing the computer + Tax
h = number of hours required to repair the computer.
Hence, the Cost (amount) to repair the computer = 50 × h = 50h
In the expression, we have
0.08(50h) = 8% of 50h
Tax is always represented as percentage of the cost of fixing the computer
Hence, 0.08 or 8% of 50 h equal to = 0.08(50h) = The tax Deborah is paying.
Therefore, the expression repesents the amount of tax Deborah has to pay is 0.08(50h)
Leslie decides to join a gym. She must pay a monthly fee plus a one-time fee to open a membership. This situation can be modeled by the expression 55x + 50. Explain how each number and letter in the expression relates to the problem.
Answer:
see below (I hope this helps!)
Step-by-step explanation:
The x seems to represent the number of months that Leslie has joined the gym for. When x = 0 (basically when she hasn't started using her membership), she pays 55(0) + 50 = $50 so we know that the 50 represents the one-time fee. The only thing missing is the monthly fee and since we haven't defined what the 55 means, we can conclude that the 55 represents the monthly fee. This makes sense because 55x is simply 55 times x, and since x is the number of months, 55 times that would be how much Leslie pays per month, otherwise known as the monthly fee.
Answer 55.1

Which statement is true about the sum of two rational numbers? It can always be written as a fraction. It can never be written as a fraction. It can always be written as a repeating decimal. It can never be written a terminating decimal. ?
Answer:
It can always be written as a fraction.
Step-by-step explanation:
The importance of this question is to differentiate rational and irrational numbers.
Rational numbers can be written as a ratio, hence a fraction, or a repeating or terminating decimal.
Irrational numbers cannot be written as a ratio and will not have a terminating or repeating decimal.
So the first statement is true since the sum of two rational numbers will be rational.
The second statement is false since the sum of two rational numbers can absolutely be represented by a fractional ratio.
The third statement is false since the sum of two rational numbers is not always a repeating decimal.
The fourth statement is false since the sum of two rational numbers could be written as a terminating decimal.
Cheers.
I agree with the other person's response. The sum is always rational (it can always be written as a fraction of integers)
----------------
Here's a proof:
Let x and y be two rational numbers. This means
x = a/b
y = c/d
where a,b,c,d are integers. The denominators b and d cannot be 0.
----------------
Let's add x and y, then simplify
x+y = (a/b) + (c/d)
x+y = (ad/bd) + (bc/bd)
x+y = (ad+bc)/(bd)
This last expression is in the form p/q
p = ad+bc is an integer
q = bd is also an integer
we have a ratio or fraction of integers, therefore x+y is also rational

The circumference of a circle is 11π inches. What is the area, in square inches, of the circle? Express your answer in terms of π. a 32.25 π b 95.03 π c 30.25 π d 17.27 π
Answer:
30.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
11 pi = 2 * pi *r
divide each side by 2 pi
11/2 = 2 ( pi) * r/ ( 2pi)
11/2 = r
We can find the area by
A = pi * r^2
= pi ( 11/2) ^2
= pi ( 121/4)
= pi ( 121/4)
= 30.25 pi
Answer:
[tex]\Huge \boxed{30.25 \pi}[/tex]
Step-by-step explanation:
The circumference of a circle formula is:
[tex]C= \pi d[/tex]
The circumference is given, solve for d.
[tex]11\pi=\pi d[/tex]
Cancel [tex]\pi[/tex] from both sides.
[tex]11=d[/tex]
The radius is half the measure of the diameter.
[tex]\displaystyle r=\frac{11}{2} =5.5[/tex]
The area of a circle formula is:
[tex]A=\pi r^2[/tex]
Let r = 5.5, solve for the area.
[tex]A=\pi (5.5)^2[/tex]
[tex]A=\pi (30.25)=30.25\pi[/tex]
3.2k - 4.3 = 12.6k + 14.5
Answer:
k = -2
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
3.2k - 4.3 = 12.6k + 14.5
Step 2: Subtract 3.2k on both sides
-4.3 = 9.4k + 14.5
Step 3: Subtract 14.5 on both sides
-18.8 = 9.4k
Step 4: Divide both sides by 9.4
k = -2

The function has a y-intercept of (2,0).
The function has an x-intercept of (0,8).
The function has an x-intercept of (2,0).
The function has an x-intercept of (4,0).
The function has a y-intercept of (0,8).
The function has a y-intercept of (4,0).
Answer:
third, fourth and fifth
Step-by-step explanation:
The y- intercept is the coordinates of the point where the graph crosses the y- axis. At this point the x- coordinate is zero, thus
The function has a y- intercept at (0, 8 ) → fifth
The x- intercepts are the coordinates of the points where the graph crosses the x- axis. At these points the y- coordinate is zero, thus
The function has an x- intercept at (2, 0 ) →third
The function has an x- intercept at (4, 0 ) → fourth

The function h(t) --4.922 +17.69+575 is used to model the height of an object being tossed from a tall building, where h(t) is
the height in meters and t is the time in seconds. What are the domain and range? Round to the nearest hundredth.
domain: [0, 12.76]
range: (1.80, 590.90)
domain: [1.80,12.76]
range: [1.80, 590.90)
domain: [1.80,12.76]
range: [0, 590.90]
domain: [0, 12.76]
range: [0,590.90]
Answer:
The correct option is;
Domain: [1.8, 12.76]
Range: [0, 590.90]
Step-by-step explanation:
The given function is h(t) = -4.92·t² + 17.69·t + 575
The maximum height reached is found from equating the derivative of the function to 0 as follows;
d(h(t))/dt = d(4.92·t² + 17.69·t + 575)/dt = -2×4.92·t + 17.69
d(h(t))/dt = 0 gives;
-2×4.92·t + 17.69 = 0
-9.84·t + 17.69 = 0
-9.84·t = -17.69
t = -17.69/-9.84 = 1.79 ≈ 1.8
h(1.8) = -(4.92×1.8²) + 17.69×1.8 + 575 = 590.9
Also we have from equating the function to zero
h(t) = -4.92·t² + 17.69·t + 575 = 0
(t - 12.75)(t + 9.2) = 0
Therefore, when t = 12.76 h(t) = 0,
Therefore, we have; the domain which is the set of values of the independent variables is [1.8, 12.76]
The range = [0, 590.90].

A worker bee flies 5/8 of a mile in 1/16 of an hour. At this rate, how far can the bee fly in 1 hour?
Answer:
10 miles
Step-by-step explanation:
So we know that it flies 5/8 of a mile in 1/16 of an hour. So after flying 5/8 of a mile 16 times, we will reach an hour. So we can do 5/8*16 and we get our answer of 10. So the bee will have traveled ten miles.

height of building A = 64 meters
height of building B = 87 meters
=====================================================
Explanation:
Refer to the diagram below.
I have added points A,B,C,D to help find the heights needed.
Focus on triangle BAC. This is a right triangle with 58 degrees as one of the known acute angles (angle BAC = 58). Also known is the adjacent side AB = 40. The unknown side we're after is side BC
------------------
tan(angle) = opposite/adjacent
tan(angle BAC) = BC/AB
tan(58) = BC/40
40*tan(58) = BC
BC = 40*tan(58)
BC = 64.013381161642
BC = 64 meters approximately
This is the approximate height of building A
---------------------
Now focus on triangle DAB
This is another right triangle. The acute angle is now 30 degrees as this is the angle of elevation.
tan(angle) = opposite/adjacent
tan(angle DAB) = DB/AB
tan(30) = DB/40
40*tan(30) = DB
DB = 40*tan(30)
DB = 23.094010767585
DB = 23 meters approximately
Add this onto BC to get
DC = DB+BC
DC = 64+23
DC = 87
Building B has a height of roughly 87 meters
--------
note: a more accurate value would be
DC = DB+BC
DC = 40*tan(30) + 40*tan(58)
DC = 87.107391929227
but when we round this to the nearest meter, we still get DB = 87
I set a goal to drink 64 ounces of water a day. If I drink 3 1/10 ounces in the morning, 2 1/15 ounces at noon, and 6 5/20 ounces at dinner, how many more ounces of water do I have to drink to reach my goal for the day?
Answer:
You must drink 52 7/12 ounces or 52.58 ounces to reach the goal.
Step-by-step explanation:
Total amount of the water already drank is found by adding the fractions
So
3 1/10 ounces + 2 1/15 ounces + 6 5/20
Converting into improper fractions
31/10 + 31/15+ 125/20
Now finding the lcm of 10,15,20
so Factors of 10 = 2 x 5
Factors of 15 = 5 x 3
Factors of 20 = 2 x2 x5
LCM= 5x2x2x3= 60
31*6/60 + 31*4/60 + 125*3/60
= 186+124+375/60
= 685/60 = 11.42 ounces
The amount of water already drank is 11.42 ounces
The amount remaining is found by subtracting the amount drank from the total amount
so
64 ounces - 11.42= 52.58
It can be solved in fractions as
64- 11 5/12
Again taking making improper fraction and taking lcm
64- 137/12
= 768-137/12 = 631/12= 52 7/12 ounces
