Which line of symmetry for the parabola (x-1)^2= 4(y-1)^?

Answers

Answer 1

This is a vertical parabola, because (x-1)².
Vertex of the parabola (1,1).
So line symmetry is x=1.

Answer 2

The line of symmetry for the parabola is x = 1.

The line of symmetry for the parabola is x = 1. In the given equation (x-1)^2 = 4(y-1)^2, the x-coordinate of the vertex is 1, which means the line of symmetry is a vertical line passing through x = 1.

Anyone know this geometry question? Will give brainiest

Answers

If AC must be parallel with BD and m∠6 is doubled, m∠3 must be doubled too.

This is because of the following rule:
When two lines are parallel, which is the occasion with AB and CD, then the corners in which the intecepting parallel lines (AC and BD) stand must be the same. So corner 6 is equivalent to corner 3, corner 1 and corner 5. Corner 2 and corner 4 are equivalent too.

For this case we have the following function:

f (x) = 2x-1 if 3 <= x <6
We observe that the function is defined from x = -4 (including it) to x = 6 (without including it).

Write the function associated with the graph below

Answers

That's a positive slope... I don't know if that's the kind of answer you're looking for, but it's a start I guess.

Since the value of the function is decreasing exponentially as x decreases ,

The function is of the form [tex] y=ae^{bx}+c,b>0 [/tex].

Since the curve passes through (0,6),

[tex] 6=ae^{0}+c,6=a+c [/tex],

Since the curve passes through (-1,0),

[tex] 0=ae^{-b}+c [/tex].

Since [tex] y=-3 [/tex] is a horizontal asymptote,

[tex] -3=ae^{-\infty}+c,c=-3 [/tex]

From the above 3 equations,

[tex] c=-3,a=9,9e^{-b}=3,e^b=3,b=\ln 3 [/tex].

Therefore, the required function is

[tex] y=9e^{\ln 3 x}-3\\
y=9*3^{ x}-3 [/tex].

It can be verified that the curve [tex] y=9*3^{ x}-3 [/tex] passes through [tex] (-2,-2) [/tex].

2. How many real number solutions are there to the equation 0 = –3x² + x – 4? (1 point)

Answers

given
[tex] - 3 {x}^{2} + x - 4[/tex]
finding the determinant will tell us how many solutions
the determinant is
[tex] {b}^{2} - 4ac[/tex]
so we have
a=-3
b=1
c=-4

so the determinant is
[tex] {1}^{2} - 4( - 3)( - 4) = 1 - 48 = - 47[/tex]
now we know if d=0 there is 1 real solution if d<0 there are complex solutions and if d>0 there are 2 real solutions.
since d=-47<0 there are no real solutions only complex ones

Final answer:

The equation has no real number solutions.

Explanation:

To find the number of real number solutions to the equation 0 = –3x² + x – 4, we can use the discriminant of the quadratic equation. The discriminant is calculated as b² - 4ac, where a, b, and c are coefficients of the equation in the form ax² + bx + c = 0. If the discriminant is positive, the equation has two distinct real solutions. If the discriminant is zero, the equation has one real solution. And if the discriminant is negative, the equation has no real solutions.

In this case, a = -3, b = 1, and c = -4. Let's calculate the discriminant:

b² - 4ac = (1)² - 4(-3)(-4) = 1 - 48 = -47

Since the discriminant is negative, the equation 0 = –3x² + x – 4 has no real number solutions.

A quilt is in the shape of a regular pentagon. It is made from 5 pieces of fabric that are congruent triangles. Each triangle has an area of 16 inches.What is the area of the quilt?

Answers

Multiply 16 × 5 because each triangle is 16 inches and you have 5 triangles.

16 × 5 = 80

The area of the quilt is 80 inches².

Final answer:

The area of the quilt, which is a regular pentagon made from five congruent triangles, is 80 square inches, determined by multiplying the area of one triangle (16 inches) by five.

Explanation:

The area of the quilt which is in the shape of a regular pentagon can be determined by calculating the area of the five congruent triangles that make up the pentagon. Since each triangle has an area of 16 inches, we can find the total area by simply multiplying the area of one triangle by the number of triangles.

To calculate the total area of the quilt:

First, determine the area of one triangle, which is given as 16 inches.Next, since there are five congruent triangles in the pentagon, multiply the area of one triangle by 5.The total area of the quilt would be 16 inches (per triangle) × 5 triangles = 80 inches.

Therefore, the total area of the quilt is 80 square inches.

the product of the number of emails received initially and one plus the factor of decrease raised to the number of years that the amount of emails Gareth received has increased

the product of the number of emails received initially and the factor of increase raised to a period of x years

Answers

The correct answer is Option A.

The formula to find the number of emails x years after making the email account is:

[tex]N(x)= N_{o}(1+0.07)^{x} [/tex]

where, [tex] N_{o} [/tex] is the number of emails in the first year.

So, the number of emails x years after creating the account is the product of [tex] N_{o} [/tex], the number of emails in first year, and (1+0.07)^x, the sum of 1 and rate of increased raised to the number of years.

Their product will be rational. Can I see the answer options?

Correct options are Options B, D, E. The product of two rational expressions (a/b) and (x/y) is a rational expression, specifically the ratio of ax and by, or equivalently ax/by. Incorrect options include ay/bx and a/y(x/b).

To determine the product of two rational expressions (a/b) and (x/y), where b ≠ 0 and y ≠ 0, let's explore the given options. Here are the truths about the product:

The product is a rational expression: When you multiply two rational expressions, the result is also a rational expression. This follows from the definition of rational expressions, which are ratios of polynomials.

The product is the ratio of ax and by: Mathematically, multiplying the numerators and denominators of the two rational expressions gives us (ax)/(by).

The product is equivalent to ax/by: This restates the above ratio in a simplified expression form, confirming that the multiplication results in (ax)/(by).

As we can see, the other expressions mentioned (ay/bx, a/y(x/b), a/(y(x/b))) are not correct representations of the product. Correct options are Options B, D, E.

Complete question:

An inscribed angle is one that has it's vertex on the circumference. <BAC is an example. A is the vertex.

A major angle is the part above BC that goes around the circle such that the angle is larger than 180 degrees. It is described above by BAC going clockwise. It is associated with the arc of a circle.

A minor angle is the angle not included in the major angle. In this case it is the angle formed by sweeping around from B to C underneath the chord BC

Hope this helps !

Final answer:

To find the area of the segment, subtract the area of the triangle from the area of the sector.

Explanation:

To find the area of one segment formed by a square with sides of 6 inches inscribed in a circle, we need to find the area of the sector formed by the circle and subtract the area of the triangle formed by the diagonal of the square.

First, find the radius of the circle using the given square. The diagonal of the square is equal to the diameter of the circle. Using the Pythagorean theorem, we have: r = s×√2/2 = 6×√2/2 = 3√2 inches.Next, find the area of the sector. The formula for the area of a sector is: A = (θ/360) × π r2. Since the square is inscribed in the circle, the angle θ is 90 degrees. Plugging in the values, we have: A = (90/360) × π (3√2)2 = π (9/2) square inches.Finally, find the area of the triangle. The diagonal of the square divides it into two congruent right triangles. The area of one of the triangles is: A = (1/2) b h = (1/2) × 6 × 6 = 18 square inches. Since there are two triangles, the total area of the two triangles is 36 square inches.To find the area of the segment, subtract the area of the triangle from the area of the sector. The area of the segment is: A = π (9/2) - 36 = (9π/2) - 36 square inches. This is the exact form of the area of one segment formed by the square inscribed in the circle.
