Answer:
B. [tex]y = -\frac{3}{10}x + \frac{1}{2}[/tex]
Step-by-step explanation:
Well slope-intercept form is [tex]y = ax + b[/tex].
Let's start with the slope.
In this case, finding the slope is easy.
It should have a negative slope.
So we can cross out answer choices A. and C.
Also, we can cross out D. because it just makes no sense, -10/3, if you start from the y-intercept and go down 10 and across 3, yeah that's
not the slope.
So we can cross out D.
The only answer choice left is B.
We can tell the y-intercept is 1/2 because like come on so B is the correct answer.
B. [tex]y = -\frac{3}{10}x + \frac{1}{2}[/tex]
Looking at the graph, we can figure out our y-intercept or b simply by looking at the line to see where it intersects the y-axis.
So, we can see that the line intersects the y-axis at 1/2 or 0.5
That means, our y-intercept or b is 1/2 (0.5).
Now, to find out the slope of the line, we can pick two pairs of coordinates on the line and plug it into the slope equation to figure out the slope.
Let's use the two coordinate pairs: (-5, 2) and (0, 1/2).
Plug it in.
1/2 - 2 = - 1.5
0 - - 5 = 5
-1.5/5 = -0.3
Convert it into a fraction: -0.3 = -3/10
Thus, our slope intercept form for this line is: y = -3/10 + 1/2

A tree planter is paid $0.11 for every tree he plants. If a particular person plants 1,356 trees in an 8 hour day, how much money per hour is he earning over minimum wage this day, if minimum wage is $11.20 per hour?
Answers
Answer:
$7.45/hour
Step-by-step explanation:
$0.11/tree
1,356 trees/day
1,356 trees/day * $0.11/tree = $149.16/day
1 day of work = 8 hours
$149.16/day * (1 day of work)/(8 hours) =
= 149.16/8 $/hour
= $18.645 $/hour
Rounded to the nearest cent, he is earning $18.65 $/hour
18.65 - 11.20 = 7.45

The functions f(x) and g(x) are shown on the graph.
f(x)=|x|
What is g(x)
Answers
Answer:
Option B
Step-by-step explanation:
As shown in the picture, g(x) is the red one which can be obtained by translating f(x) - the blue one toward +x-axis direction 4 units.
=> g(x) = f(x) + 4 = |x| + 4
Answer: Choice D
g(x) = |x-4|
=================================================
Explanation:
Replacing x with x-4 shifts the xy axis four units to the left. If we fix the blue V shape to not move while the xy axis does move, then it gives the illusion of the V shape moving 4 units to the right to end up producing the red curve.
You can use a table of values to compare the two functions or you could use a graphing tool to confirm the answer.
--------
Extra info:
Choice A will move the blue graph 4 units down
Choice B will move the blue graph 4 units up
Choice C will move the blue graph 4 units to the left

In square units, what is the area of the sector that is not shaded?
Answers
Answer:
[tex] A = 350\pi \approx 1100 [/tex]
Step-by-step explanation:
The shaded area is a sector with a central angle of 45 deg.
The total measure of the central angle of a full circle is 360 deg.
The central angle of the unshaded sector is
360 deg - 45 deg = 315 deg
The area of a sector of a circle with a central angle of n degrees and a radius r is
[tex] A = \dfrac{n}{360}\pi r^2 [/tex]
[tex] A = \dfrac{315}{360}\pi \times 20^2 [/tex]

[tex] y = 9.1 [/tex]
Step-by-step explanation:
Use the Law of sines to find y in ∆WXY, given:
m < Y = 106°
m < X = 58°
WY = x = 8
WX = y = ?
Therefore,
[tex] \frac{y}{sin(Y)} = \frac{x}{sin(X)} [/tex]
[tex] \frac{y}{sin(106)} = \frac{8}{sin(58)} [/tex]
[tex] \frac{y}{0.961} = \frac{8}{0.848} [/tex]
[tex] \frac{y}{0.961} = 9.434 [/tex]
Multiply both sides by 0.961 to solve for y
[tex] \frac{y*0.961}{0.961} = 9.434*0.961 [/tex]

Answers
Answer: Annette will take 6 hours to do the entire job alone.
Step-by-step explanation:
Given: Time taken by Kelly to do [tex]\dfrac{1}{5}[/tex] of job = 2 hours
i.e. Time for complete job done alone by Kelly =[tex]5\times2=10\ hours[/tex]
Rest of work = [tex]1-\dfrac{1}{5}=\dfrac{4}{5}[/tex] of the job
[tex]\dfrac{4}{5}[/tex] of the complete job done by both Kelly and Annette in 3 hours
Time would be taken by then to do entire job together = [tex]3\times\dfrac{5}{4}=3.75\ hours[/tex]
Let t be the time taken by Annette to do job alone.
Then, as per situation
[tex]\dfrac{1}{3.75}=\dfrac{1}{10}+\dfrac{1}{t}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{3.75}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{4}{15}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{6}\\\\\Rightarrow\ t=6[/tex]
hence, Annette will take 6 hours to do the entire job alone.
Find the area of this parallelogram.
Answers
Answer:
A = 105 inches^2
Step-by-step explanation:
The area of the parallelogram is
A = bh
A = 7 inches * 15 inches
A = 105 inches^2
Finding the area of a parallelogram is very similar to finding the area to that of a rectangle.
The equation for area A is [tex]A=bh[/tex] where b is the base length and h is the height.
We are given a base length of 15 inches, and the height of the parallelogram is 7 inches (not 9 inches).
[tex]A=(15 \text{ in})(7 \text{ in})\\[/tex]
[tex]=105 \text{ in}^2[/tex]
The area of the parallelogram is 105 square inches. Let me know if you need any clarifications, thanks!
What is the vertex of the quadratic equation below? y=x^2-8x+1 Explanation?
Answers
To find the vertex, you need to find the axis of symmetry first.
In order to find the axis of symmetry we have to do -b/2a.
In our case, the b is -8 and the a is 1.
Plug it in.
-(-8)/2(1)
8/2 = 4
Our axis of symmetry is 4.
Now, we plug it into the equation to find the rest of the vertex.
y = 4^2 - 8(4) + 1
y = 16 - 32 + 1
y = -16 + 1
y = -15
Put it together.
Our vertex is (4,-15).
1. A rectangle measures 6 cm by
4 cm. Another rectangle with adjacent
sides o on and x cm is geometrically
similar to it.
Find the two possible value of x.
Answers
Answer:
Two figures are similar if they have the same shape:
For example, two rectangles are similar if the quotient between length and wide is the same.
Now, we know that one of the rectangles is 6cm by 4cm.
The quotient of the lengths is 6cm/4cm = 3/2
Here we have a problem; you wrote
" Another rectangle with adjacent
sides o on and x cm ....."
I guess that this means:
The other triangle has one side with a measure of x cm, and the other side will have the lenght A, a constant number that you can complete after.
Now, if this new triangle is similar to the first one, then we must have;
If x > A.
x/A = 6cm/4cm = 3/2
x = (3/2)*A.
if x < A
A/x = 6cm/4cm = 3/2
x = (2/3)*A
There you have the two possible values of x, for a known A.

Which figure will tessellate the plane? A. regular pentagon B. regular decagon C. regular octagon D. regular hexagon
Answers
A hexagon is composed of 6 congruent equilateral triangles. Each equilateral triangle has interior angle of 60 degrees. Adding 6 such angles together gets you to 360 degrees. So we've done one full rotation and covered every bit of the plane surrounding a given point. Extend this out and you'll be able to cover the plane. A similar situation happens with rectangles as well (think of a grid, or think of tiles on the wall or floor)
In contrast, a regular pentagon has interior angle 108 degrees. This is not a factor of 360, so there is no way to place regular pentagons to have them line up and not be a gap or overlap. This is why regular pentagons do not tessellate the plane. The same can be aside about decagons and octagons as well.

If a company buys coffee at a price of $5/kg and then sells it their stores for $18/kg, what is the percentage profit compared to the original cost of the coffee?
Answers
Answer:
260%
Step-by-step explanation:
For the coffee;
cost price ([tex]C_{P}[/tex]) = $5/kg
selling price ([tex]S_{P}[/tex]) = $18/kg
Percentage profit (%P) = [tex]\frac{S_P - C_P}{C_P} * 100%[/tex] %
Substitute the right values into the above;
%P = [tex]\frac{18 - 5}{5} * 100%[/tex] %
%P = [tex]\frac{13}{5} * 100%[/tex] %
%P = 260%
Therefore, the percentage profit compared to the original cost of the coffee is 260%
Given that StartFraction D F Over P R EndFraction = StartFraction F E Over R Q EndFraction = three-halves, what additional information is needed to prove △DEF ~ △PQR using the SSS similarity theorem?
Answers
Answer:
The additional information required to prove ΔDEF ~ ΔPQR is the value of the ratio DE/PQ which has to be equal to three-halves for ΔDEF to be similar to ΔPQR
Step-by-step explanation:
Given DF/PR = FE/RQ = 3/2
The Side Side Side, SSS, similarity theorem states that where there are two triangles that have corresponding sides that are proportional to each other, the two triangles are said to be similar
Given ΔDEF and ΔPQR, have sides DF/PR = FE/RQ, to prove that ΔDEF and ΔPQR, then the additional information required is the ratio of the third sides of the triangles which is DE/PQ.
If DE/PQ = Three-halves, the two triangles ΔDEF and ΔPQR are similar, if not, that is DE/PQ ≠ Three-halves, then the two triangles ΔDEF and ΔPQR are not similar.
