Answer:
(x-5)^2 + (y-6)^2 = 9
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2 where ( h,k) is the center and r is the radius
(x-5)^2 + (y-6)^2 = 3^2
(x-5)^2 + (y-6)^2 = 9

Given the equation y = 2x - 8, what is the slope and the y-intercept? A.) m = 8 and b = 2 B.) m = 2 and b = 8 C.) m = 2 and b = -8 D.) m = -8 and b = 2
Answer:
C.) m = 2 and b = -8
Step-by-step explanation:
Generally:
In an equation of the form y = mx + b
the slope is m
the y-intercept is b
In our equation y = 2x - 8 = 2x + (-8)
then
m = 2 and b = -8

To the nearest square unit, what is the area of the regular heptagon shown below?
Answer:1572
Step-by-step explanation:
Am god
To the nearest square unit, Area of heptagon = 1572 square unit
The correct option is B.
What is heptagon?A heptagon is a polygon with 7 sides and 7 angles. Sometimes the heptagon is also known as “septagon”. All the sides of a heptagon meet with each other end to end to form a shape.
Given,
Side length of heptagon = 20.8 unit
Radius of the incircle = 21.6 unit
Perimeter of heptagon = 7×side = 7×20.8 = 145.6 unit
Area of heptagon = (1/2)Perimeter × radius of incircle
= 0.5 × 145.6 × 21.6
= 72.8 × 21.6
= 1572.48 square units
Hence, 1572 square unit is the area of the heptagon rounded to nearest square unit.

Si una persona de lunes a viernes entrena diariamente 1 hora ¿cuanto tiempo debe entrenar el sábado para que el promedio diario de las horas de entrenamiento de los 6 días sea 1,5 horas?
Answer: 4 horas
Step-by-step explanation:
Una semana (de lunes a viernes) contiene 5 días
Si se entrena 1 hora por día:
1 x 5 = 5 horas (total de horas de entrenamiento de lunes a viernes)
Ese total más el número de horas que se entrena el sábado (x) dividido por 6 (numero de días en la semana incluyendo sábado) debe ser igual a el promedio de horas entrenadas en los 6 días (1.5)
(5+x) /6 =1.5
Despajando x:
5+x =1.5 x 6
5+x =9
x =9-5
x = 4 horas

Answer:
12/36 = 1/3
Step-by-step explanation:
draw a possibility diagram or table where you get the possible outcomes. 1 to 6 along the bottom and 1 to 6 across.
you will results such as 11 12 13 14 15 16
21 22 23 24 25 26
and so on.
Then, you total up each of them and will get
2 3 4 5 6 7 from the first row
3 4 5 6 7 8 from 2nd row
and so on.
from the final results, count how many are multiples of 3.
we should get 12 and over total possible outcomes which is 36, since it's a 6 by 6 table.

Answer:
A (1,0), B (3,0) Q (2,-1) P(0,3)
Step-by-step explanation:
A(1,0) B (3,0) these are the roots of the current graph so the factors or the x-intercepts.
Q is the minimum so it is halfway between the x-intercepts
halfway = 3+1/2 , x=2
plug x=2 into the equation
y=(2-1)(2-3)
y= -1
therefore Q = (2,-1)
P is the y-intercpet when x=0, so plug x=0 into the equation
y=(0-1)(0-3) = 3
therefore Q =
(0,3)

what are the solutions of x^2-4x-9=29
Answer: x =(4-√168)/2=2-√ 42 = -4.481
x =(4+√168)/2=2+√ 42 = 8.481
Step-by-step explanation:
Answer:
x = -4.48, 8.48 to the nearest hundredth.
Step-by-step explanation:
x^2 - 4x - 9 = 29
Completing the square:
(x - 2)^2 - 4 - 9 = 29
(x - 2)^2 = 29 + 13 = 42
x - 2 = +/-√42
x = 2 +/-√42
x = 8.48, -4.48 .

What is area model?In area model for multiplication a rectangle is used to represent multiplication between two quantities. Width and Length of the rectangle are assigned the numerical value of the two quantities being multiplied.
Solution
Let the number of skills be represented by the length of the rectangle in the figure.
Let the time spent(in hours), which is same for all skills, on each skill be represented by the width of the rectangle in the figure.
The area of the rectangle = length × width = 5 × t = 5t hours.
This area represents total time spent on five skills, which is 5/6 hours.
The smaller rectangles into which the whole rectangle is divided have area 1 × t = t hours. This represents time spent on one skill.
From the figure, such five smaller and equal rectangles constitutes the whole rectangle.
So, area of one smaller rectangle = Area of big rectangle / number of small rectangles = (5/6)/5 = 1/6 hours.
Since, this represents time spent on one skill. So, the required time is 1/6 hours.
She practice each skill for 1/6 of an hour.

Does this equation y=87.2/x represent a direct or inverse variation?
Answer:
Inverse relationship
Step-by-step explanation:
The equation we are looking at is;
y = 87.2/x
which implies xy = 87.2
If it was a direct relationship
y = constant * x
if it was inverse, it would have been
y * x = constant
since 87.2 is a constant, the question looks exactly like the second scenario.
This means that what we have is an inverse relationship
