Let (x,y) be an arbitrary point on the circle.
Then d = √[x-3)2 + (y-0)2] = √[x2 - 6x + 9 + y2]
Since x2 + y2 = 1, y2 = 1-x2.
So, d = √[x2 - 6x + 9 + 1 - x2]
d = √(-6x+10)
Domain: x is the x-coordinate of a point on the circle centered at (0,0) with radius 1. So, -1≤x≤1.
But, for d to be defined, we need -6x+10 ≥ 0. So, x ≤ 5/3 (True for all x in [-1,1]).
Domain = [-1,1]
Range: -1 ≤ x ≤ 1 So, 6 ≥ -6x ≥ -6
16 ≥ -6x+10 ≥ 4
4 ≥ √(-6x+10) ≥ 2 That is, 2 ≤ d ≤4
Range: [2,4]

What is the equation of the line that passes through the point (3, -3) and has a
slope of o?
Answer:
y = -3
Step-by-step explanation:
point = (3, -3)
slope (aka m) = 0
y = mx + b
-3 = (0)(3) + b
b = -3
y = (0)x - 3
y = -3
what is the slope perpindicular to line 5x+3
Answer:
[tex]-\frac{1}{5} x+b[/tex] (b can equal any number- you can use 3)
Step-by-step explanation:
To find the slope, you take mx (in this case 5x), get the number by itself, flip the sign, then get the reciprocal.
5 -> -5 -> [tex]-\frac{1}{5}[/tex]
What is the domain and range please?
Answer:

In 2010 the Network Club membership was 2,500. With an annual growth rate of approximately 8%, compounded continuously, what will the membership be in 2020?
Answer:
5563.85 But round the nearest whole number is 5564
Step-by-step explanation:
Formule is P=Ie^(r)(t)
If, In 2010 the Network Club membership was 2,500. With an annual growth rate of approximately 8%, compounded continuously, then 5563.85 is the population in 2022.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
In 2010 the Network Club membership was 2,500.
Annual growth rate of approximately 8%
8% is converted to decimal value by dividing 8 with 100
8/100=0.08
[tex]P=Ie^{rt}[/tex]
p is the final population
I is the initial population
[tex]p=Ie^{0.08(10)}[/tex]
[tex]p=2500e^{0.8}[/tex]
p=5563.85
Hence, 5563.85 is the population in 2020.

y+3=2(x+5), write the equation of the line in slope intercept form.
Answer:
slope intercept form: y=mx+b
y+3=2(x+5)
step 1: use distributive property
y+3=2(x)+2(5)
y+3=2x+10
step 2: subtract 3 on both sides to make y by itself
y+3=2x+10

The ratio of boys to girls in a camp is 6 to 8. How many girls are there in the camp if there are 96 boys in the camp?
Answer:
128 girls
Step-by-step explanation:
The ratio of boys to girls is 6 to 8. We need to find how many girls there are if there are 96 boys in the camp. One way to solve this is by using cross multiplication:
[tex]\frac{6}{8}[/tex] = [tex]\frac{96}{x}[/tex]
multiply the 6 by the x: 6x
multiply 8 by 96: 768
6x = 768
divide both sides of the equation by 6 to isolate the x:
6x/6 = 768/6
x = 128
When there are 96 boys in camp, there will be 128 girls.
Answer:
6/8=96/x

09) The ratio of the number of jackfruit in baskets P, Q
and R is 6:2:5. The total number of jackfruit
in basket Pis 48 more than the number of
jackfruit in basket Q. Calculate the total number
of jackfruits in the three baskets.
A 121 B 144 C 156 D 169
Answer:
156 jackfruits
Step-by-step explanation:
Let there are 6x jackfruit in baseket P, 2x in basket Q and 5x in basket R.
The total number of jackfruit in basket P is 48 more than the number of jackfruit in basket Q. ATQ,
6x = 48 + 2x
Solving for x.
6x - 2x = 48
4x = 48
x = 12
Jackfruits in basket P = 6x = 6(12) = 72
Jackfruits in basket Q = 2x = 2(12) = 24
Jackfruits in basket R = 5x = 5(12) = 60
Total no of jackfruits = 72 + 24 + 60
= 156
So, there are 156 jackfruits in the three baskets.

A chocolate box has the shape of a prism with a base that is a
rhombus. Each side length of the rhombus is 3.6 cm.
The angles between adjacent sides of the base are 60° and 120°.
The prism is 10.8 cm long.
a) Draw a net for this box.
b) How is your net different from the cardboard net from
which the box is made? Explain.
Part (a)
See the diagram below for the net for this box. We have two rhombuses that are the two bases of the rhombic prism. The six rectangles form the lateral sides.
In geometry, a net is effectively the outer surface of a 3D object, but it has been laid flat on a plane. Think of unwrapping a present without throwing any pieces away. The net would be the wrapping laid out flat. As another example, a net of a cardboard box would be laying the box flat. So you're unfolding the box. This is mentioned in part (b).
====================================================
Part (b)
The main difference from this net compared to a net for a cardboard box is that everything is a rectangle for a cardboard box. This is because a cardboard box folds up into a rectangular prism.
So in the diagram below, you'll replace each rhombus with a rectangle. You'll make all four angles 90 degrees.

Read the excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde.
This hall, in which he was now left alone, was a pet fancy of his friend the doctor’s; and Utterson himself was wont to speak of it as the pleasantest room in London. But tonight there was a shudder in his blood; the face of Hyde sat heavy on his memory; he felt (what was rare with him) a nausea and distaste of life; and in the gloom of his spirits, he seemed to read a menace in the flickering of the firelight on the polished cabinets and the uneasy starting of the shadow on the roof. He was ashamed of his relief, when Poole presently returned to announce that Dr. Jekyll was gone out.
Which statement best describes how the author establishes mood in the excerpt?
a.The author’s description of the grand room creates an admiring mood.
b.The author’s description of physical symptoms creates an anxious mood.
c.The author’s mention of Utterson’s thoughts creates a sentimental mood.
d.The author’s mention of Utterson’s spirits creates a spiritual mood.
Answer:
b.The author’s description of physical symptoms creates an anxious mood.

Step-by-step
measure angle 1 is corresponding to measure angle 5
measure angle 5= measure angle 1= 71*
measure angle 5 + measure angle 8 = 180*
71*+ measure angle 8=180*
measure angle 8=109
Answer:
[tex]m\angle5 = 71\degree^{\circ}[/tex],
[tex]m\angle8=109^{\circ}[/tex]
Step-by-step explanation:
Given that [tex]a[/tex] and [tex]b[/tex] are parallel and [tex]m\angle1=71^{\circ}[/tex]:
[tex]m\angle5 = 71^{\circ}[/tex] (Corresponding angles are equal when [tex]a\parallel b[/tex] )
[tex]m\angle8+m\angle5=180^{\circ}[/tex] (The two angles make up the angle of a straight line: [tex]180^{\circ}[/tex]
[tex]m\angle8 + 71^{\circ} = 180^{\circ}[/tex]
[tex]m\angle8 = 109^{\circ}[/tex]
[tex]\therefore m\angle5=71^{\circ};m\angle8=109^{\circ}[/tex]

slope from two points
Answer:
[tex]\frac{12}{7}[/tex]
Step-by-step explanation:
use the formula [tex]\frac{y - y'}{x - x'}[/tex]
so you would get
[tex]\frac{4 - (-8)}{0 - (-7)}[/tex]
Those negatives becomes a positive and you get 4+8 = 12 and 0+7 = 7
you final answer would be [tex]\frac{12}{7}[/tex]
Answer: I am pretty sure the answer is D.
Step-by-step explanation:
so this is how u find the slope from two points... You have (-7,-8) and (0,4) you then take -7 and subtract that by 0 so -7-0 and then -8-4. and -7-0/-8-4 = 7/12. plz tell me if I am wrong.

Constant
Variable
Answer:
in -7y y is variable and -7 is Constant
Step-by-step explanation:
Constant: A number that cannot change its value. In the expression 2x+4y−9 , the term 9 is a constant. Like Terms: Terms that contain the same variables such as 2m , 6m or 3xy and 7xy
variable is a symbol which functions as a placeholder for varying expression or quantities, and is often used to represent an arbitrary element of a set.
