Which are the foci of the hyperbola represented by 5x2 – 4y2 + 80 = 0?
Step-by-step explanation:
[tex]5 {x}^{2} - 4 {y}^{2} + 80 = 0[/tex]
[tex]5 {x}^{2} - 4 {y}^{2} = - 80[/tex]
[tex] - \frac{ 5{x}^{2} }{16} + \frac{ {y}^{2} }{20} = 1[/tex]
[tex] \frac{ {y}^{2} }{20} - \frac{5 {x}^{2} }{16} = 1[/tex]
To find foci,
[tex]c = \sqrt{ {a}^{2} + b {}^{2} } [/tex]
so
[tex]c = \sqrt{20 + 16} [/tex]
[tex]c = \sqrt{36} [/tex]
[tex]c = ±6[/tex]
Since the y term has a greater denomiator, our foci is
(0,6) and (0,-6)
identify the figure with the vertices A (3,5) B (3,1) C (0,1)
Answer:
It makes a right traiangle.
Step-by-step explanation:
Graph the points and you will see that it makes a right triangle.
The figure formed by the vertices A(3,5), B(3,1), and C(0,1) is a right-angled triangle.
In this triangle, side BC is the shortest side with a length of 3 units, side AB is the longest side with a length of 4 units, and side AC has a length of 5 units.
The right angle is formed between side BC and side AC at point C (0,1).
Here, we have to identify the figure with the given vertices A (3,5), B (3,1), and C (0,1), we can plot these points on a coordinate plane.
Let's plot the points A(3,5), B(3,1), and C(0,1) on a Cartesian coordinate plane.
A(3,5): This point is located at x-coordinate 3 and y-coordinate 5.
B(3,1): This point is located at x-coordinate 3 and y-coordinate 1.
C(0,1): This point is located at x-coordinate 0 and y-coordinate 1.
Since point A and point B share the same x-coordinate (x = 3), they lie on a vertical line. Point C has a different x-coordinate, so we need to connect it with the others to complete the figure.
The figure formed by connecting the points A, B, and C is a right-angled triangle.
To calculate the distances between the vertices, we'll use the distance formula:
Distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is given by:
Distance = √[tex]((x_2 - x_1)^2 + (y_2 - y_1)^2)[/tex]
Let's calculate the distances:
Distance between A(3,5) and B(3,1):
Distance_AB = √[tex]((3 - 3)^2 + (1 - 5)^2)[/tex]
Distance_AB = √(0 + 16)
Distance_AB = √16
Distance_AB = 4 units
Distance between A(3,5) and C(0,1):
Distance_AC = √[tex]((0 - 3)^2 + (1 - 5)^2)[/tex]
Distance_AC = √[tex]((-3)^2 + (-4)^2)[/tex]
Distance_AC = √(9 + 16)
Distance_AC = √25
Distance_AC = 5 units
Distance between B(3,1) and C(0,1):
Distance_BC = √[tex]((0 - 3)^2 + (1 - 1)^2)[/tex]
Distance_BC = √[tex]((-3)^2 + 0^2)[/tex]
Distance_BC = √9
Distance_BC = 3 units
As we calculated, the distances between the vertices of the figure are:
AB = 4 units
AC = 5 units
BC = 3 units
Based on the distances, we can determine that the figure formed by the vertices A(3,5), B(3,1), and C(0,1) is a right-angled triangle.
In this triangle, side BC is the shortest side with a length of 3 units, side AB is the longest side with a length of 4 units, and side AC has a length of 5 units.
The right angle is formed between side BC and side AC at point C (0,1).

Is (3,-3) a solution of the graphed system of inequalities?
Choose 1 answer:
(A) Yes
(B) No
Answer:
(B) No
Step-by-step explanation:
If I remember correctly a solution is a point that is on the shaded area or on a solid line, the point 3,-3 is not on the shaded region and not on a solid line. Even if it was on the line in this problem it wouldn't be a solution because it is a dotted line. Hope this helps!

We know that 8x+19=139
8x+19=139

x=15
If k(x) = 5x - 6, which expression is equivalent to (k + k)(4)?
Answer:
Answer:
Expression equivalent to (k + k)(4) is 28.
Step-by-step explanation:
Given:
k(x) = 5x - 6
We need to find an expression equivalent to (k + k)(4)
First, we find,
(k + k)(x) = k(x) + k(x)
= ( 5x - 6 ) + ( 5x - 6 )
= 5x - 6 + 5x - 6
= 5x + 5x - 6 - 6
= 10x - 12
Now, (k + k)(4) = 10(4) - 12 = 40 - 12 = 28
Therefore, the Expression equivalent to (k + k)(4) is 28.
The angles shown are supplementary What is
the value of x One angle is 3x and the other is 96
Answer:
x = 28
Step-by-step explanation:
Supplementary angles mean that both angles are equal to 180. So, the equation becomes 3x + 96 = 180. Solving for x, we get 28.
Answer:
The value of x is 28
Step-by-step explanation:
Given :
Angles are supplementary One angle = 3xOther angle = 96Now,
Supplementary angles are a pair of angles that make sum of 180° .
Therefore, The sum of given angles will be equal to 180°.
i.e. one angle + other angle = 180°
Substituting the values of angles , we get..
[tex]⇢3x + 96 = 180[/tex]
[tex]⇢3x = 180 - 96[/tex]
[tex]⇢3x = 84[/tex]
[tex]⇢x = \frac{84}{3} [/tex]

Answer: 0.9
Step-by-step explanation: All you need to just keep your decimal (0.9) as it is since 4 and 2 are below 5 then you don't need to round it higher. I hope this helped!
0.942
to find:the nearest tenth of 0.942
solution:to round to the nearest tenth, if the number in hundredths place is 5 or more you'll have to round up, if not keep it as it is and remove all the digits in the right side.
=0.9
hence, the nearest tenth of 0.942 is 0.9
Joanne is making punch. She uses 1/2 gallon of orange juice, 3 quarts of lemonade, and 1 1/4 gallons of apple cider. How many quarts of punch will she have all together?
Answer:
10 Quarts
Step-by-step explanation:
First, convert 1/2 gallons into quarts. 1/2x4=2. Then convert 1 1/4 to quarts. 1 1/4x4=5. Finally, add it all togher. 2+5+3=10. So, the answer is 10 quarts.

Do you think that extrapolation or interpolation is more accurate? Explain.
Answer:
Interpolation is used to predict values that exist within a data set, and extrapolation is used to predict values that fall outside of a data set and use known values to predict unknown values. Often, interpolation is more reliable than extrapolation, but both types of prediction can be valuable for different purposes

the pre image of a line has the equation y=-7x. this line is translated -5 units along the x-axis and the 8 units along the y-axis. which is the equation of the image of this line?
ill mark you brainliest if youre right
Answer:
(b) y = -7x -27
Step-by-step explanation:
When x and y in the equation y = f(x) are replaced by (x-h) and (y-k), the function graph is translated h units right and k units up. The translated function can be written as ...
y -k = f(x -h)
y = f(x -h) +k . . . . . . add k
__
Your function is ...
y = -7x
and you want to translate it by (h, k) = (-5, 8). That makes it ...
y' = -7(x -(-5)) +8 = -7x -35 +8
y' = -7x -27

What is its radius ?
We are given that:
Circumference = 19.4 cm
Formula:
2πr = Circumference
Rewrite the equation:
⇒ 2πr = Circumference = 19.4 cm⇒ 2πr = 19.4 cmThe "r" variable represents the radius of the circle. Thus, we need to isolate it on one side to determine the radius. This can be done with the four mathematical operations (+ - × ÷). Since the "÷" is included, we can divide both sides by 2π to isolate the "r" variable.
Divide both sides by 2π:
⇒ 2πr/2π = 19.4 cm/2π⇒ r = 9.7 cm/πSubstitute the radius as 22/7:
⇒ r = 9.7 cm ÷ 22/7⇒ r = 9.7 cm x 7/22⇒ r = 67.9/22 cmHave you ever uploaded a photo you took to a social media site? If so, there is a good chance that because you agreed to the social media company’s terms of service, the company can use your photo for promotional reasons. Do you think it is okay that social media companies make users agree to let them use users’ photos? Why or why not?
Compare what you think about social media companies using users’ photos to people claiming photos they found online as their own. Is one practice worse than the other? Why or why not?
Write one to two sentences explaining what you think about social media companies requiring users to agree to the company using their images for promotional purposes. Provide at least one reason that supports your idea.
Write two to three sentences comparing people claiming photos they found online as their own to social media companies using user images. Provide at least one reason that supports your idea.
Answer:
I think it would be fine if they notified you but only if they used me for a good reason.
On the other hand...
no matter if it's on the agreement if it is inappropriate on your part it is illegal and you can complain.
