give the coordinates(enclose the coordinates in parentheses) of the
foci,vertices,and convertices of the ellipse with equation x²/169 + y²/25 = 1
Answers
Answer:
\(\frac{x^2}{169} +\frac{y^2}{25}=1\)
If we compare this to the general expression for an ellipse given by:
\(\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2}=1\)
We can see that the vertex is \( V=(0,0)\)
And we can find the values of a and b like this:
\( a=\sqrt{169}=13, b=\sqrt{25}=5\)
in order to find the foci we can find the value of c
\( c =\sqrt{169-25}=\sqrt{144}=12\)
The two focis are (12,0) and (-12,0)
The convertices for this case are: (13,0) and (-13,0) on the x axis
And for the y axis (0,5) and (0,-5)

Where will X be after a rotation 90° clockwise about (-5,-1)?
Click on the grid to place the point.
Answers
The image point of the coordinate X after the rotation is (-1, 5).
Calculating the image point of the coordinate XWhen a point is rotated 90° clockwise around the origin, the new point will be formed by switching the x and y-coordinates and then negating the new x-coordinate.
So for point X (-5, -1), the new x-coordinate will be -1, and the new y-coordinate will be -(-5) = 5, giving the new point (-1, 5).
Therefore, after a rotation of 90° clockwise, point X (-5, -1) will be at the new location (-1, 5).

What is meant by an angle?An angle in Euclidean geometry is the figure produced by two rays, called the sides of the angle, that have a common termination, called the vertex of the angle. Angles formed by two rays lie in the plane containing the rays. Angles are also generated by the intersection of two planes. These are referred to as dihedral angles. Two intersecting curves can also define an angle, which is the angle of the rays lying tangent to the respective curves at their point of intersection.
Given,
m ∠GQP=80
m ∠RQP=3+59x
m ∠RQG=32x+4
From the figure,
m ∠RQG+ m ∠GQP= m ∠RQP
32x+4+80°=3+59x
27x=81°
x=3°

b) lowest z score
c) z score closest to zero

By answering the above question, we may state that Romania $766.51 $646.96.80 leu 0.940 and by equation United States $4,141.00 $1,242.20 dollars 0.000 $4,141
What is equation?A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematics statement that proves the equality of two formalisms is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two statements that are inscribed on opposite sides of a letter. Frequently, the trademark and the particular software are identical. like in 2x - 4 = 2, for example.
z = (x - μ) / σ

Which of the following numbers is between 4 1/3 and 4 3/5 on a number line?
A) 4.1
B) 4.2
C)4.3
D)4.4
Answers
The number 4.4 is between \(4 \frac{1}{3}$\) and \(4 \frac{3}{5}$\) on the number line, so the answer is (D) 4.4.
How to solve improper fraction?To solve this problem, we need to convert the mixed numbers 4 1/3 and 4 3/5 to improper fractions and then find a number between them on the number line.
\(4 \frac{1}{3}$\) can be written as \(\frac{13}{3}$\) and \(4 \frac{3}{5}$\) can be written as \(\frac{23}{5}$\).
To find a number between \(\frac{13}{3}$\) and \(\frac{23}{5}$\), we need to find a common denominator. The least common multiple of 3 and 5 is 15, so we can rewrite the fractions with a denominator of 15:
\($\frac{13}{3} = \frac{65}{15}$\)
and
\($\frac{23}{5} = \frac{69}{15}$\)
Now we can see that the number \(\frac{67}{15}$\) is between \(\frac{65}{15}$\) and \(\frac{69}{15}$\), and we can convert it back to a mixed number:
\($\frac{67}{15} = 4 \frac{7}{15}$\)
Therefore, the number 4.4 is between \(4 \frac{1}{3}$\) and \(4 \frac{3}{5}$\) on the number line, so the answer is (D) 4.4.
