1. Draw an accurate picture of the triangle in the coordinate axes, as shown in the attached picture.

2. Circumscribe a rectangle about the triangle, as shown in the picture. The coordinates of the points M, N, T are easily identifiable as shown in the picture.

3. The area of the triangle ABC is  The area of the rectangle - Area 1- Area 2- Area 3.

Area 1 = 1/2(3*7)=21/2
Area 2 = 1/2(4*4)=1/2*16=8
Area 3 = 1/2( 3*7)=21/2

Area 1+Area 2+Area 3=21/2+21/2+8=21+8=29 (units squared)

Area rectangle=  7*7=49 (units squared)


Answer: Area of triangle is 20 units squared.

The rule for inscribed angles and their corresponding arcs is that the measure of the angle is one-half that of the arc. Therefore, all we have to do is divide 68/2, which gets us an answer of D. 34.

Hope this helps!

The domain of a function corresponds to the x-values. Therefore, we can disregard the y-values altogether. Finally, all we have to do is put together the values in the x-column. This gets us an answer of B. {3, 4, 5, 6}.

Hope this helps!

I cant see the question but can u pull it up

For information on the meaning of 50/100/50 see
https://www.linkedin.com/pulse/have-you-seen-50100100-your-auto-insurance-policy-do-know-vancura

50=bodily injury max 50000 per individual
so the payment would be 8000+50000+20000=78000 before deductibles and coinsurance, if any is applicable.

Check the picture below

make sure your calculator is in Degree mode.

The mean for the first seven weeks is given:


The median for the first seven weeks is given by the middle value of the data after being set in ascending order

277   481   647   684  712   770   853

The middle value is the 4th value, so Median = 684
----------------------------------------------------------------------------------------------------------------

Assuming Jerry wins the price for the 8th week, the new mean is given


The new Median is now located between the 4th and 5th value, which is the mid value between 684 and 712.
A quick way to work this out is (684+712)÷2 = 698
---------------------------------------------------------------------------------------------------------------

The increase in mean is 1803-632 = 1171
The increase in Median is 698 - 684 = 14

Correct answer is d

The rule for inscribed angles to arcs is that the measure of the arc is double the measure of the angle. Therefore, we do 36 x 2, which gets us an answer of B. 72.

Hope this helps!

None......................................

Basically it is asking, for example:
If you move the decimal from 654 three places to the right, would the 10^ have a 10^- or a 10^+

Is this a joke? If so, not sure.

2 is a great answer you should use......

-We cannot add 32 to both sides yet since it is attached to F within the parenthesis. 
-It is not subtract F from both sides since the F is already separated on the opposite side from C. 
-We cannot divide F because it is still within the parenthesis. 
I assume by 5959 you mean 5/9 and by 9595 you mean 9/5. So by multiplying 
each side by 9/5, you are able to isolate the parenthesis (F-32). 
9/5C= F-32
If you wanted to solve the equation all the way through, you would just add 32 to each side. 

So.. take a peek at the picture... let's get two points from it, hmm say 0,4 notice it touches the y-axis there, and say hmmm -4, 1, almost at the bottom of the line





once you get the slope and solve for "y", that'd be the equation of the line.

Yes because 100 percent is 10 hrs so 1 more hr is 110 percent. And if u try to put it in a equation it will be 110%

Same thing, add all numbers but y, but divided by 6 now since there are 6 numbers on the left.

Plot -5 on the x axis and 1 on the y axis . 

If 4 points r coplanar we have many technic to find but the shortcut is to lock at the points 
Example : Let 4 points A(1,1) , B(-1,1) ,C(-1,-1), D(1,-1) 
Here, A is in 1st co-ordinate , B is in 2nd co-ordinate , C is in 3rd co-ordinate and D is in 4th so if the 4 points had same - or + number for x and y as in P(x,y) then they r coplanar 

The formula for the area of the circle is:

All you have to do is plug in 8 for r :)

Given the graph, we need to look for the equation of the line using the linear equation since the plot is obviously a line.

To do that, we need two points. The simplest points to locate are the two points that converges the x and y axes which are (3,0) and (4,0), respectively. Now we apply the linear equation formulation:

y = mx+b

First, we need to get the slope.

m = (y2-y1)/(x2-x1)
m = (4-0)/(0-3)
m = -4/3

Since we know the slope, we need to look for the b which is also the y-intercept or the point at which x = 0.

So at x = 0, which point or value at y-axis hits with the line? It is the point (0,4).
Therefore, b = 4.

Completing the equation,

y = -(4/3)x + 4

or we can write it as

4x + 3y = 12.

Now to know which of the choices is correct, we simply assign values and see for ourselves which is true.

Let x = 2, so y = 2

4(2) + 3y = 12
8 < 12

If you assign more values, you will notice that 4x + 3y is always less than or equal to 12. Thus, the answer is letter a.

We have 
Stock = $200
Bonds = $100

Substitute these values into 1.08s+1.02b, where 's' is stock and 'b' is bond


Predicted end of year value is $318

The solution is where the lines cross. So your x coordinate is 3.

Check the picture below

solve for "x"

YES THEY WILL YOUR WELCOME.

Assume the radius is R.

2*pi*R = 28 -> R = 14/pi

So the area will be pi*R^2 = 196/pi

Based on the given answers, do you possibly mean 100 instead of 102?
If so, you would move the decimal point of 8.4 two places to the right, meaning the answer would be letter D. 840.

I'm trying to solve this too did u find it out???

Assuming the +'s are actually x's  1/2 of 3 is 1.5 and 1.5 divided by 7 is 1.5/7.(answer is 1.5/7) hopefully I'm right.
