How will the solution of the system change if the inequality sign on both inequalities
Answers
Shown below
Step-by-step explanation:The first system of inequality is the following:
[tex]\left\{ \begin{array}{c}y>2x+\frac{2}{3}\\y<2x+\frac{1}{3}\end{array}\right.[/tex]
To find the solution here, let's take one point, say, [tex](0,0)[/tex] and let's taste this point into both inequalities, so:
FIRST CASE:First inequality:
[tex]y>2x+\frac{2}{3} \\ \\ 0>2(0)+\frac{2}{3} \\ \\ 0>\frac{2}{3} \ False![/tex]
The region is not the one where the point [tex](0,0)[/tex] lies
Second inequality:
[tex]y<2x+\frac{1}{3} \\ \\ 0<2(0)+\frac{1}{3} \\ \\ 0<\frac{1}{3} \ True![/tex]
The region is the one where the point [tex](0,0)[/tex] lies
So the solution in this first case has been plotted in the first figure. As you can see, there is no any solution there
SECOND CASE:First inequality:
[tex]y<2x+\frac{2}{3} \\ \\ 0<2(0)+\frac{2}{3} \\ \\ 0<\frac{2}{3} \ True![/tex]
The region is the one where the point [tex](0,0)[/tex] lies
Second inequality:
[tex]y>2x+\frac{1}{3} \\ \\ 0>2(0)+\frac{1}{3} \\ \\ 0>\frac{1}{3} \ True![/tex]
The region is not the one where the point [tex](0,0)[/tex] lies
So the solution in this first case has been plotted in the second figure. As you can see, there is a solution there.
CONCLUSION: Notice that when reversing the signs on both inequalities the solution in the second case is the part of the plane where the first case didn't find shaded region.

27 units
33 units
36 units
51 units
PLEASE HELP, IT WOULD BE AWESOME IF YOU COULD
Answers
Answer: 36 units
Step-by-step explanation:
once you plot out the points, it shows a polygon. cut the polygon into a square and a triangle, and count the units to get the lengths, widths, and heights.
you find that the height of the square is 6, and the width is 5. multiply those to get the area of the square: 30.
the width of the triangle is 2 units, and the height is 6. multiply those to get 12, then divide it in half to get the area: 6.
then you add the area of the square to the area of the triangle to get the total area of 36 units squared.

which pair of triangles can be proven congruent by the HL theorem
Answers
The answer is C
Step-by-step explanation:
The pair of given triangles which satisfied the HL theorem of congruency is given by option C. Both right triangles with hypotenuse and one corresponding leg congruent.
HL theorem also named as Hypothenuse Leg theorem,
It states hypotenuse and any one leg of one right angled triangle is congruent to hypotenuse and corresponding leg of another right angled triangle.
This implies both the triangles are congruent using HL theorem.
To check which pair of triangles are congruent using HL theorem are as follow,
a. In the first pair of right angled triangles only hypotenuse is marked as congruent side of two different triangles.
So it is not true.
b. In the second pair of triangles,
Both the triangles are obtuse angled triangle.
It does not satisfied HL theorem.
So , it is also not true.
c. In the third pair of the right angled triangle,
Hypotenuse of both the triangle are marked congruent.
One of the corresponding leg is also congruent.
It satisfied the HL theorem.
And both the triangles are congruent to each other using HL theorem.
Option C. is true.
d. IN fourth pair of triangles,
Triangles are not right angled triangle.
It satisfied the SSS (Side -Side- Side) congruency theorem.
It is not a correct option for HL theorem.
Therefore, pair of triangles which satisfied the HL theorem of congruency is option C. Both right triangles.

Answers
Answer:
[tex]V=5,676.16cm^3[/tex]
Step-by-step explanation:
The volume of a triangular prism is defined by the formula:
[tex]V=(area-of-base)*(length)[/tex]
In this case the base is triangular and the area of a triangle is: [tex]A=\frac{1}{2}(base)*(height)[/tex]
Then the volume is:

let f(x) = 5/x and g(x)=2x2+5x. What two numbers are not in the domain of f o g
Answers
Answer:
0 and -5/2
Step-by-step explanation:
g is the first function we consider because that is the function we are first plugging in values into since the order is f o g and not g o f.
g has domain all real numbers meaning you can plug in any number into g and get a number back
So now let's look at plugging in g(x) into f(x)
that is f(g(x))=f(2x^2+5x)=5/(2x^2+5x)
Here you are dividing by a variable
You have to watch out dividing by 0
The variable, 2x^2+5x, is 0 when....
2x^2+5x=0
x(2x+5)=0
x=0 or x=-5/2
So The domain is all real numbers except x=0 or x=-5/2
[tex](f \circ g)(x)=\dfrac{5}{2x^2+5x}\\\\2x^2+5x\not =0\\x(2x+5)\not=0\\x\not =0 \wedge x\not =-\dfrac{5}{2}[/tex]

Using the triangle pictured, find the measure of side AB. Round your answer to the nearest tenth. A) 1.6 B) 2.2 C) 2.7 D) 3.3
Answers
Answer:
Option B (AB = 2.2 units).
Step-by-step explanation:
The diagram shows that there are two sides given and one angle is given. Therefore, the sine rule must be used to solve the question. The sine rule can be written as:
sin ABC / AC = sin BAC / BC.
Plugging ABC=72 degrees, AC=2.5, and BC=2.1 in the sine rule gives:
sin 72 / 2.5 = sin BAC / 2.1.
Cross multiplying gives:
sin BAC = (2.1*sin 72)/2.5.
sin BAC = 0.79888747368.
Taking sin inverse on both sides gives:
BAC = arcsin (0.79888747368) = 53.0239949 degrees.
To find AB, first, the angle ACB is required. To find that angle, use the triangular law of angles. All the three angles sum up to 180 degrees. Therefore ACB = 180 - 72 - 53.0239949 = 54.9760051 degrees.
Now applying the Sine Rule to find AB:
sin ACB / AB = sin ABC / AC.
sin (54.9760051) / AB = sin 72 / 2.5.
AB = (2.5*sin (54.9760051))/sin (72) = 2.2 (to the nearest tenth).
Therefore, AB = 2.2 units, i.e. Option B!!!

The distance between the pair of points A(-1,8) and B(-8,4) is 15.
In geometry, the distance formula is:

Now we can just plug in the x and y values:
√(-1-8)2+(8-(-4)2
√(-1-8)2+(8+4)2
√(-9)2+(12)2

#SPJ2
Final answer:
The distance between points A(-1,8) and B(-8,4) is calculated using the distance formula derived from the Pythagorean Theorem and is approximately 8.06 units.
Explanation:
To find the distance between two points on the Cartesian plane, you can use the distance formula, which is derived from the Pythagorean Theorem. In this case, the points are A(-1,8) and B(-8,4). The formula is as follows:
d = √((x2 - x1)² + (y2 - y1)²)
Here's how it's done step-by-step:
Subtract the x-coordinates of the two points: -8 - (-1) = -7.
Subtract the y-coordinates of the two points: 4 - 8 = -4.
Square both differences: (-7)² = 49 and (-4)² = 16.
Add the squares of the differences: 49 + 16 = 65.
Take the square root of the sum:
√65 approx 8.06.
Therefore, the distance between points A and B is approximately 8.06 units.

Choose the possible descriptions of cross sections formed by the intersection of a plane and a cylinder choose all that apply
-circle
-rectangle
-triangle
-line segment
-point
Answers
Answer:
circle and rectangle
Step-by-step explanation:
we know that
A cross section that is perpendicular to the base of cylinder is a rectangle
A cross section that is parallel to the base of cylinder is a circle
A cross section that is angled to the base of cylinder is an oval
Final answer:
A plane intersecting a cylinder can create a circle if perpendicular to the cylinder's axis, or a rectangle if cut parallel to the side of the cylinder. Ellipses are also possible when the cutting angle is oblique, and may look circular from certain perspectives. Triangles, line segments, and points are not typical cross sections for a cylinder.
Explanation:
When a plane intersects a cylinder, several different cross sections can result, depending on the angle and position of the plane relative to the cylinder. If the plane is perpendicular to the axis of the cylinder, the cross section will be a circle. If the plane intersects the cylinder at an angle to the axis, the cross section can be an ellipse, which in some cases may appear to be a circle depending on the perspective. A plane intersecting parallel to the side of the cylinder will produce a rectangle. It is not possible for a cylinder to have a triangular, line segment, or point as a cross section through normal slicing, as these do not represent the way planes intersect with the smooth curved surface of a cylinder.

Answer:

Step-by-step explanation:
Look at x and then look at the sides that are given... 9 is adjacent and 17 is the hypotenuse so use cosine.
cos(x)=9/17
To solve for x just use arccos( ) or cos^(-1)
Type cos^(-1)(9/17) into calc to receive answer (make sure mode is in degrees)
The answer should come to be roughly 58 deg.
Answer:
x ≈ 58.0°
Step-by-step explanation:
Since the triangle is right use the cosine ratio to solve for x
cosx° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{9}{17}[/tex], thus
x = [tex]cos^{-1}[/tex] ([tex]\frac{9}{17}[/tex] ) ≈ 58.0°
Find the missing value so that the two points have a slope of -17/10 (-3,9) and (x,-8)
Answers
Answer:
x=7
Step-by-step explanation:
slope formula: (y2-y1)/(x2-x1)
(-8-9)/(x-(-3))=-17/10
-17/x+3=10
-17/7+3=10
-17/10=10
To find the missing value so that the two points have a slope of -17/10, we can use the slope formula. Substituting the coordinates into the formula, we get an equation -17/(x + 3) = -17/10. Solving for x, we find x = 7.
Explanation:To find the missing value so that the two points have a slope of −17/10, we can use the slope formula. The slope formula is (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. In this case, the first point is (-3, 9) and the second point is (x, -8).
Substituting the coordinates into the slope formula,
we have (-8 - 9) / (x - (-3)) = -17/10.
Simplifying this equation,
we get -17 / (x + 3) = -17/10.
Cross multiplying, we find x + 3 = 10.
Solving for x, we subtract 3 from both sides, giving x = 7.
Therefore, the missing value is 7.
