We're working on Area of a Triangles on Coordinate Grids what's the area of this triangle here? The screenshot attachment is the problem that needs to be solved. If someone could answer quickly I would appreciate it! This is geometry by the way.
Answers
Answer:
11.5 square units
Step-by-step explanation:
It’s a 4 by 6 rectangle, so the total is 24. Then subtract the three little triangles on the outside. (Much easier than doing the main triangle).
1/2x1x4=2
1/2x1x6=3
1/2x3x5=7.5
2+3+7.5=12.5
24-12.5=11.5

What are the end behaviors of f(x) = (1/3)^x – 2 ?
Answers
Answer:
[tex]\lim_{x\to -\infty} f(x)=\infty,\\\lim_{x\to \infty} f(x)=2,[/tex]
Step-by-step explanation:
The end behaviors of a function simply denote where the function is headed at x approaches negative and positive infinity. In [tex]f(x)=\left(\frac{1}{3}\right)^x+2[/tex], as [tex]x[/tex] gets approaches [tex]-\infty[/tex], the function will approach [tex]y=\infty[/tex]. As [tex]x[/tex] approaches [tex]\infty[/tex], the function will approach [tex]y=2[/tex].
We can write this in the following format to denote these end behaviors:
[tex]\lim_{x\to -\infty} f(x)=\infty,\\\lim_{x\to \infty} f(x)=2,[/tex]

Find the percent of the area under the density curve where x is more than 3.
Answers
Answer:
The percent of the area under the density curve where [tex]x[/tex] is more that 3 is 25 %.
Step-by-step explanation:
Since the density curve is a linear function, the area under the curve can be calculated by the geometric formula for a triangle, defined by the following expression:
[tex]A = \frac{1}{2}\cdot (x_{f} - x_{o})\cdot (y_{f}-y_{o})[/tex] (1)
Where:
[tex]A[/tex] - Area, in square units.
[tex]x_{f} - x_{o}[/tex] - Base of the triangle, in units.
[tex]y_{f} - y_{o}[/tex] - Height of the triangle, in units.
The percent of the area is the ratio of triangle areas under the density curve multiplied by 100 per cent, that is:
[tex]x = \frac{\frac{1}{2}\cdot (5-3)\cdot (0.25) }{\frac{1}{2}\cdot (5-1)\cdot (0.5) }\times 100\,\%[/tex]
[tex]x = 25\,\%[/tex]
The percent of the area under the density curve where [tex]x[/tex] is more that 3 is 25 %.

Answers
Answer:
6x - y + 17=0
Step-by-step explanation:
Given :-
The slope of the line is 6 and it passes through (-2,5) .And we need to find out the equation of the line. Using the point slope form. The point slope form of the line is ,
[tex]:\implies[/tex] m ( x - x1) = ( y - y1)
[tex]:\implies[/tex] 6( x -(-2)) = ( y -5)
[tex]:\implies[/tex] 6( x +2) = y -5
[tex]:\implies[/tex] 6x +12= y -5
[tex]:\implies[/tex] 6x - y +17=0
Hence the equation of the line is 6x - y +17=0The perimeter of a rectangular painting is 244 centimeters. If the width of the painting is 51 centimeters, what is the length?

Find the critical points of the following functions. Use the Second Derivative Test to determine (if possible) whether each critical point corresponds to a local maximum, a local minimum, or a saddle point. If the Second Derivative Test is inconclusive, determine the behavior of the Junction at the critical points. f(x,y)=x^4y^2
Answers
Answer:
In a function of two variables, the critical points are these in which both derivatives are 0, and if:
[tex]\frac{d^2f}{dx^2}*\frac{d^2f}{dy^2} - [ \frac{d^2f}{dxdy} ]^2 < 0[/tex]
the point is a saddle point.
If the above equation is larger than zero, the critical points can be either a local maximum or a local minimum.
If it is equal to zero, no conclusions can be made.
First, let's find all these derivatives.
df/dx = 4*(x^3)*(y^2)
This is zero when x or y are equal to zero.
df/dy = 2*(x^4)*(y)
This is equal to zero when either x or y are equal to zero.
So in both cases, the points of the form:
(x, 0) and (0, y) are zeros of the first derivative, so these are the critical points.
Now let's look at the second derivatives:
[tex]\frac{d^2f}{dx} = 4*3*x^2*y^2 = 12*x^2*y^2[/tex]
[tex]\frac{d^2f}{dy^2} = 2*x^4[/tex]
[tex][\frac{d^2f}{dxdy} ]^2 = (4*x^3*2*y)^2 = 64*x^6*y^2[/tex]
Then, the equation to see if the points are saddle points or not are:
[tex](12*x^2*y^2)*(2*x^4) - 64*x^6*y^2 < 0[/tex]
In any of the previous found points (the ones of the form (x, 0) and (0, y)) the above equation will be equal to zero, then none of these points is a saddle point. More than that, in the particular case where the above equation is equal to zero, the critical points can be either: A relative minimum, a relative maximum, or a saddle point (so we need more analysis to find it out)
But in this case is ratter simple, because both powers in f(x, y) are even, we can conclude that the function is even and symmetric about x= 0 and y = 0, and the function is also positive, so all the points:
(0, y) and (x, 0) are the minimum values that f(x, y) can take.
Then the critical points are relative minimums.

Step-by-step explanation:

Required
The changes that makes it to: [tex]y =|x| - 1[/tex]
By observation, we can see that [tex]y =|x| - 4[/tex] was translated up to [tex]y =|x| - 1[/tex]
Next, is to calculate the units of translation (c)
Represent the old function as:
[tex]y=\left|x\right|-4 + c[/tex]
Equate y and y
[tex]\left|x\right|-4 + c =\left|x\right|-1[/tex]
Cancel out |x|
[tex]-4 + c=-1[/tex]
Solve for c
[tex]c = 4 - 1[/tex]
[tex]c = 3[/tex]

Clark and his friends bought strawberry wafers for $2 per packet and chocolate wafers for $3 per packet at a carnival. They spent a total of $30 to buy a total of 14 packets of wafers of the two varieties.
Part A: Write a system of equations that can be solved to find the number of packets of strawberry wafers and the number of packets of chocolate wafers that Clark and his friends bought at the carnival. Make sure you say what each variable means! (Which one is which wafer type?)
Part B: How many packets of chocolate wafers and strawberry wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer.
Answers
Answer:
Step-by-step explanation:
A. S=strawberry, C=chocolate
S+C=14 equation 1
2s+3c=30 equation 2
B. -2(s+c)=-2(14) multiply equation 1 by -2 to use elimination method
-2s+-2c=-28 modified Equation 1
2s+ 3c=30. Equation 2
C=2 add above two equations.
solve for s
s+c=14
s+2=14
s=12
Used elimination method since it was easier to add the two equations.
check answer by inputting s,c values in either equation.
2s+3c=30
2(12)+3(2)=30

Answer:
2s+3c=30s+c=142 chocolate12 strawberryStep-by-step explanation:
Part A:
I like to use variable names that remind me what they stand for. Here, we can use s and c for the numbers of strawberry and chocolate packets, respectively. The two equations we can write based on the problem statement are ...
2s + 3c = 30 . . . . . . . the total cost of the purchase
s + c = 14 . . . . . . . . . . the number of items purchased
__
Part B:
Ordinarily, I would use one equation for the problem. That equation can be arrived at by substituting for s using the second equation. We choose to substitute for s so the only remaining variable is the one representing the highest-value contributor to the total cost.
s = 14 -c
2(14 -c) +3c = 30 . . . . substitute for s
28 +c = 30 . . . . . . . . . simplify (notice the coefficient of c is positive)
c = 2 . . . . . . . . . . . subtract 28
s = 14 -2 = 12 . . . . find s using the above equation
They bought 2 packets of chocolate and 12 packets of strawberry wafers.
__
Explanation of choices
When the total purchase is n items and x of them are of one kind, then n-x is the number of the other kind. You don't need to write a second equation to figure that out. Hence the problem can be described by a single equation, such as the one highlighted above. Doing this lets you skip a variable definition and a couple of solution steps you don't really need.
The choice of variable as being the high-cost item ensures that its coefficient in the equation will be positive. Fewer errors are made when arithmetic is done with positive numbers. Again, recognizing that early on saves headaches down the line.
Getting to a generic solution
Note that the number we subtract (28) is the "would be" cost of all of the items purchased being the lowest-cost item (14 strawberry packets). This recognition can let you do the entire problem in your head. The difference between the actual cost and the "would be" cost is the result of replacing some number of the lowest-cost items with the higher-cost ones. The difference between total costs is divided by the difference in cost per item to find the number of the higher-cost item. That is the answer to all problems of this type. (30 -14(2))/(3-2) = 2 = the number of $3 packets.

$35 and $55 each, how many of each type of ticket were sold?
Answers
Answer:
Step-by-step explanation:

35a+55b=432500 equation 2
a=9500-b modified equation 1 to isolate a
35(9500-b)+55b=432500 substitute value of a in equ 1 into value of a equ 2
332500-35b+55b=432500
20b=100000
b=5000
solve for a
a + b=9500
a + 5000=9500
a=4500
