how do you write the equation from a rose graph
Answer:
equation is in form: r = a cos(nθ) or r = a sin(nθ)
If length of petal is given in graph, that gives a value.
n value is from number of petals
Step-by-step explanation:
hope this helps :D
(btw I hate rose graphs...)
Answer:
Rose curve equations have two forms: r = a cos(nθ) and r = a sin(nθ) where a ≠ 0 and n is a positive integer. Petals have length determined by a. If n is odd, the number of petals is n. However, if n is even, the number of petals is 2n.

Which class has the largest ratio of boys to girls
Answer:
You need to calculate (# of Boys) / (# of Girls + # of Boys). The largest ratio will be the biggest number
Step-by-step explanation:
Example:
• 55 Boys and 35 Girls
• Boys Ratio = (55) / (55 + 35)
• Boys Ratio = 55 / 90
• Boys Ratio = 61%
What is the measure of angle "A"?
Answer:
[tex]<A=106[/tex]
Step-by-step explanation:
The given figure is an isosceles trapezoid, this means that the two non-parallel sides in the trapezoid are congruent. One of the properties of an isosceles triangle is that opposite angles are supplementary. This means that the sum of angles opposite each other in an isosceles trapezoid is (180) degrees. One can apply this here by stating the following,
[tex]<A+<C=180[/tex]
Substitute,
[tex]<A+74=180[/tex]
Inverse operations.
[tex]<A=106[/tex]

Which equation matches to the graph?
1. y = -x + 1/2
2. y = (-1/2)x - 1
3. y = 2x - 1
4. y = 4x + 2
Answer:
2. y = -1/2x - 1
Step-by-step explanation:
First we want to find the slope of the line.
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values using two points (-4, 1) & (2, -2)
(-2 - 1) / (2 - (-4))
Simplify the parentheses.
= (-2 - 1) / (2 + 4)
= (-3) / (6)
Simplify the fraction.
-3/6
= -1/2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -1/2x + b
b is the y-intercept when the line crosses the y-axis.
From the graph, we can see that the point on the y-axis is (0, -1)
Therefore, b is -1.
Plug this into the equation.
y = -1/2x - 1
Hope this helps!

How do i do A for this part of flower bed area
Answer:
12.6 m2
Step-by-step explanation:
Area between lawn and flower bed is 1m on each side, so the diameter of the flower bed is 4 m2
The radius is 2 m2
Use the area formula: r^2 . Pi
4 * pi = 12.56
Tania has a set of nesting rings. This table shows the relationship between the radius of a ring and the ring's circumference.
What is the circumference for the nesting ring with a 9.5 cm radius?
Answer:
59.66 cm
Step-by-step explanation:
Circumference of a circle = 2πr
π = 3.14
r = radius = 9.5
2 x 3.14 x 9.5 = 59.66 cm

Look at the graph of the function f(x).
Which statements regarding the parabola's axis of symmetry are true? Select all that
apply.
A. The axis of symmetry is the line represented by x =
0.
B. The y-axis is the axis of symmetry.
C. If the point (a,b) is a point on the parabola, then the point (-a,b) is also a point on the parabola, because it is a reflection over the axis of symmetry.
D. The X-axis is the axis of symmetry.
Answer:
Options A, B, C
Step-by-step explanation:
From the graph attached,
Vertex of the given quadratic function → (0, 1)
Therefore, axis of symmetry → x = 0
Option A
Axis of symmetry ix the line represented by x = 0.
True
Option B
The y-axis is the axis of symmetry.
Line represented by x = 0 is the y-axis.
True
Option C
If the point (a, b) is a point on the parabola, then the point (-a, b) is also a point on the parabola, because it is a reflection over the axis of symmetry.
Rule for the reflection over y-axis is given by,
(x, y) → (-x, y)
Therefore, coordinates of the point (a, b) after reflection over the y-axis will be,
(a, b) → (-a, b)
True
Option D
The x-axis is the axis of symmetry.
False

What are the coordinates of the midpoint of CD where C(2,-6) and D(4,10)?
Answer:
The midpoint of CD is (3, 2)
Step-by-step explanation:
The movement of x is +2 from C to D and the movement of y is 16 from C to D
2 (C's x coordinate) +2/2 (to find the movement up to the x coordinate of the midpoint) and -6 (C's y coordinate) + 16/8 (to find the movement up to the y coordinate of the midpoint)
This is 2+1 as the x coordinate and -6+8 as the y coordinate that is (3, 2)
