QUESTION-1:we are given the center and the redious of a circle equation
remember that,
[tex] \rm\displaystyle E _{c} :(x - h {)}^{2} + (y - k {)}^{2} = {r}^{2} [/tex]
where (h,k) is the centre coordinate and r is redious of the circle
given that, h=-2 , k=-5 and r=1
Thus substitute:
[tex] \rm\displaystyle (x - ( - 2){)}^{2} + (y - ( - 5) {)}^{2} = {1}^{2} [/tex]
simplify:
[tex] \rm\displaystyle (x + 2{)}^{2} + (y + 5 {)}^{2} = {1}^{} [/tex]
QUESTION-2:Likewise
[tex] \rm\displaystyle E _{c} :(x - h {)}^{2} + (y - k {)}^{2} = {r}^{2} [/tex]
given that,h=7,k=-3 and r=√7
substitute:
[tex] \rm\displaystyle (x - (7{))}^{2} + (y - ( - 3){)}^{2} = { \sqrt{7} ^{2} }[/tex]
simplify:
[tex] \rm\displaystyle (x - 7{)}^{2} + (y + 3{)}^{2} = { 7 }[/tex]

Parralel lines cut by a transversal coloring activity. Please give explanation. Will give brainiest.
Step-by-step explanation: Do You Want Me To Find All The Values ?
Parallel lines intersected by a common transversal form 8 angles
The required values of y and x are;
5. y = 42°6. y = 29.5°7. y = 9°8. y = 14°9. y = 31°10. x = 20°11. x = 13°12. y = 39°The reasons why the above values are correct are given as follows:
Given the lines are parallel lines cut by a common transversal, we have;
Angles with measure (2·y - 1)° and (9·x - 38)° are same side interior angles
Angles with measure (4·x + 23)° and (2·y - 1)° are alternate interior angles
Which gives;
(2·y - 1)°+ (9·x - 38)° = 180°...(1)
(4·x + 23)° = (2·y - 1)°...(2)
From equation (1), we get;
y = 109.5 - 4.5·x
From equation (2), we get;
y = 2·x + 12
The common solution is given by; 109.5 - 4.5·x = 2·x + 12
From 109.5 - 4.5·x = 2·x + 12, we get;
x = 15,
y = 42°6) (9·x + 42)° and 15·x° are vertical angles, and therefore are equal
(9·x + 42)° = 15·x°
∴ x = 7
(4·y - 13)° and (9·x + 42)° are supplementary, therefore
(4·y - 13)° = (9·x + 42)°, which gives;
(4·y - 13)° = (9×7 + 42)° = 105°
y = 29.5°7) (3x + 11) + (x + 21) = 180
∴ x = 37
(14·y - 4)° = 3x + 11 = 3 × 37 + 11 = 122°
y = 9°8) (13·x - 33) = 10·x
∴ x = 11
10·x + 5·y = 180
10 × 11 + 5·y = 180
[tex]y = \dfrac{70^{\circ}}{5} = 14^{\circ}[/tex]
y = 14°9) (27·x + 4) + (8·x + 1) = 180
∴ x = 5
y + 10 = 8·x + 1 = 8 × 5 + 1 = 41
y = 41 - 10 = 31
y = 31°10) 16·x - 4 = 9·x - 6 + 58 = 9·x + 52
7·x = 56
x = 8
11) (6·x - 58)° + (x + 8)° = 90°
7·x - 50 = 90
7·x = 90 + 50 = 140
[tex]x = \dfrac{140}{7} = 20[/tex]
x = 20°12) 7·x - 7 = 3·x + 45°
4·x = 52
[tex]x = \dfrac{52}{4} = 13[/tex]
x = 13°
(3·x + 45)° + 63° + (y - 6)° = 180°
(3×13 + 45)° + 63° + (y - 6)° = 180°
147 + (y - 6)° = 180°
y = 39°Learn more about the angles formed between parallel lines here:

ZA and ZB are supplementary angles. If m_A = (8x – 27) and m
ZB = (4x + 3)°, then find the measure of ZA.
>_
Answer:
m<ZA = 109
Step-by-step explanation:
Supplementary angles mean the angles add up to 180 so:
8x - 27 + 4x + 3 = 180
12x - 24 = 180
12x = 180 + 24
12x = 204
x = 17
m<ZA:
8x - 27
8(17) - 27
136 - 27

El precio al contado del camión es de 80000dólares.La comunidad aceptó pagarle a la tienda Inca power una tasa de interés del 16%anual, durante 2 años. ¿Cuánto será el interés que pagará la comunidad por el camión a la tienda Inca power después de 2años? ¿Cuánto pagará la comunidad campesina al final por la compra del camión?
Answer:
Ver explicacion
Step-by-step explanation:
Dado que el precio en efectivo del camión es de $ 80 000. Luego;
P = $ 80 000
R = 16%
T = 2 años
Yo =?
Pero
I = PRT / 100
Yo = 80 000 * 16 * 2/100
I = $ 25,600
Importe total pagado = principal + intereses
Monto total pagado = 80,000 + 25,600
Monto total pagado = $ 105,600
1. Cadence has a collection of 52 dolls that all have either blue-eyes or green-eyes.
Cadence has 16 more blue-eyed dolls than green-eyed dolls. How many green-eyed dolls
does Cadence have?
Answer:
Cadence has 18 more green eyed dolls
Step-by-step explanation:
1. 52-16=36
2. 36÷2=18
The number of dolls that have blue eyes and green eyes will be 34 and 18, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Rhythm has an assortment of 52 dolls that all have either blue-eyes or green-eyes. Rhythm has 16 additional blue-looked-at dolls than green-peered dolls.
Let 'x' be the number of blue-eyes dolls and 'y' be the number of green-eyes dolls. Then the equations are given as,
x + y = 52 ...1
x = y + 16 ...2
From equations 1 and 2, then we have
y + 16 + y = 52
2y = 52 - 16
y = 36 / 2
y = 18
The value of x is given as,
x = 18 + 16
x = 34
The number of dolls that have blue eyes and green eyes will be 34 and 18, respectively.

Which type of sampling method is being employed in the following example:
“A post office manager was in charge of 11 postal delivery people. He wanted to do
a study on the customer's level of satisfaction for the customers he works with. So,
he asked 3 of his delivery people to ask every person on their delivery route to rate
their satisfaction of mail service on a scale of 1 to 10."
Answer:
Step-by-step explanation:
The sampling method employed in the given example is convenience sampling.
Convenience sampling is a non-probability sampling technique where the sample is selected based on its accessibility and convenience. In this case, the post office manager selected three delivery people from the total of 11 available. This selection was based on convenience, as they were already working for the post office.
The population in this scenario consists of all the customers the post office manager works with. Let's denote this population as N.
The post office manager used convenience sampling to select a subset of the population to participate in the study. The size of the sample is not explicitly mentioned, but we can assume it is the total number of customers on the three selected delivery routes. Let's denote the sample size as n.
Since convenience sampling does not involve random selection, the sample selected may not be representative of the entire population. The customers on the selected delivery routes may not be a fair representation of all the post office customers. This introduces a potential sampling bias.
It's important to note that convenience sampling can be quick and easy to implement but may not provide reliable or generalizable results. In this case, the post office manager may obtain information about customer satisfaction from a limited group, potentially leading to skewed or unrepresentative findings. For a more accurate and representative study, a different sampling method, such as random sampling or stratified sampling, could be employed.

Answer:
Step-by-step explanation:
since RS || VU ( parallel to ) then the angle V is equal to ∠ VRS , also we are given that ∠VRT = 71° so subtract ∠VRT from ∠VRS
103° - 71° = 32°
so ∠TRS = 32°
next find ∠U, we know that ∠U + ∠VRT= 180° ( b/c they are supplementary )
we are also told that ∠VRT = 71°
∠U = 180 - 71
∠U = 109°
Since RS || VU (parallel to) then the angle V is equal to VRS, also we are given that VRT = 71°
So subtract VRT from VRS,
103° -71° = 32°
So, TRS = 32°
next find U, we know that ZU + ZVRT= 180° (b/c they are supplementary)
We are also told that <VRT = 71"
U = 180° - 71°
U = 109° is the answer.

Isabelle went for a hike on Wednesday at camp. The hike took 2 hours and 10 minutes. As soon as she got back, Isabelle played volleyball for 1 hour and 55 minutes. It was 11:15 A.M. When Isabelle finished playing volleyball. What time did Isabelle start her hike?
Answer: 5:10 A.M.
Step-by-step explanation:
First find the total time that Isabelle spent playing volleyball and hiking.
= 2 hours and 10 minutes + 1 hour and 55 minutes
= 4 hours and 5 minutes
If she finished both activities at 11:15 am, the time she started was:
= 11:15 - 4 hours 5 minutes

Jada is using pyramid-shaped piece of foam with the dimensions shown below for a model she is making. She has to paint the triangular surfaces for her model. The slant height of each triangular face is 9mm. The base will NOT be painted. Find the SURFACE AREA of the pyramid that has to be painted.
Answer:
The answer is 90 mm squared
Step-by-step explanation:
First off, Surface Area is the combined areas of the 2D shapes that make up a 3D shape. The formula for finding the area of a triangle (the 2D shape that makes up most of a pyramid) is a = 1/2 bh, which is basically area = 1/2 base (the un-slanted line) * the height, or the middle line.
Since there are 4 triangles, you would multiply this by 4 after solving, so
sa = 4(1/2bh)
Putting the numbers in, you'd get
sa = 4(1/2*5*9)
To solve:
sa = 4(1/2*45)
sa = 4(22.5)
sa = 90mm^2
