Answer:
If the distance from the origin to a given point is 5, then that point lies on circle C is true.
Step-by-step explanation:
The correct statement about given circle is "If the distance from the origin to a given point is 5, then that point lies on circle C"
What is a circle?In mathematics, the circle is a two dimensional rounded figure which has no corner edges.
Standard form = (x - a)² + (y - b)² = r²
Given that,
The center of a circle is on origin and the radius is 5 unit.
And point p lies on the circle,
So, according to definition of circle the distance between center and any point on the circle is always constant and which is known as radius.
Therefore, the distance between center end given point will be equal to 5 then it will lies on a circle.

Answers
The most economic way to purchase health insurance for the family would be to insure Patrick with his employer and Susie and the twins with her employer (Option c).
Reason behind the Choice
Patrick's employer pays for 100% of his monthly health insurance premium of $378
In this case, additional beneficiary for the twins = $280*2 = $560
Susie's employer pays 63% of her $403 monthly premium, and is ready to pay 32% of the $310 monthly premium for each additional beneficiary.
Total money to be paid in this case = 37% of $403 +2*(68% of $310)
= $570.71
Considering that Patrick's health insurance cost is lower than Susie's, it makes sense for him to get health insurance via Patrick's company.
For the twins, Susie's employer offers to pay 68% of $310 for each additional beneficiary. So, the most viable deal would be to buy Patrick's health insurance from his employer and Susie and the twin's health insurance from her employer.

MCVI, where C is the number of cockroaches in thousands, and t is the time
in days. How many cockroaches are there at the start?
Answers
Answer:
310,000
Step-by-step explanation:
Since t represents time, the start would represent when no time has passed or in other words, when t=0, which is the y-intercept. You can plug in t as 0, but it's a bit redundant, since the y-intercept of a quadratic equation in the form: [tex]f(x)=ax^2+bx+c[/tex] will have a y-intercept at (0, c) where c is the constant, since whenever you plug in 0 as x, the ax^2 becomes 0 (since 0^2 = 0, and a * 0 = 0 since anything multiplied by 0... is 0) and the same thing goes for the bx, leaving the c alone. This means the y-intercept of the function is (0, 310) and since it's in the thousands there is 310,000 at the start

Determine the equation of the parabola shown in the diagram in factored form.
Answers
Answer:
y = (x +1)(x -3)
Step-by-step explanation:
You want the equation in factored form for the parabola shown in the graph with x-intercepts at -1 and +3, and a vertical scale factor of 1.
FactorsIf p is a zero (x-intercept) of the graphed polynomial function, then (x-p) is a factor. The graph shows x-intercepts at x=-1 and x=3. This means (x-(-1)) and (x -3) are factors.
Scale factorThe equation of the graph may also have a vertical scale factor. That can often be determined easily from the graph by looking at the vertical distance from the vertex of points 1 unit either side of the vertex.
Here, the vertex is (1, -4) and points at x=0 and x=2 have the value -3, which differs from the vertex by 1 unit. Hence the scale factor is 1. It multiplies the other factors.
The equation of the graphed parabola is ...

Please mark brainliest! Thanks!
Answer:
g(x)⁻¹ = √x + 3
Step-by-step explanation:
To find the inverse of an expression is to reverse the expression. This can be done by swapping the input and output variables. In other words, in g(x), you want to swap the places of the "x" variable the "y" variable.
Remember, g(x) = y.
y = (x - 3)² <----- Original function
x = (y - 3)² <----- Swap the variables
Now, you want to set the equation equal to "y" again. This can be done by rearranging/simplifying the expression.
x = (y - 3)² <----- Swapped variables
√x = √(y - 3)² <----- Take the square root of both sides
√x = y - 3 <----- Eliminate parentheses from previous step
√x + 3 = y <----- Add 3 to both sides
If g(x)⁻¹ represents the inverse of g(x), the new function is:
g(x)⁻¹ = √x + 3

The correct option is D, The relationship is not proportional because the ratio of pages to days is not constant.
What is a linear relationship?A linear relationship is a relationship in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c.
A linear relationship with two variables, when graphed on the cartesian plane with axes of those variables, gives a straight line.
For the given relationship to be proportional, the number of pages read should be the same every day. Therefore, the ratio of the number of pages to the number of days should be equal.
85/1 = 85
170/2 = 85
249/3 = 83

Solve the following using the distributive property:
8x+12=2(x-3)
Answers
Answer:
x = - 3
Step-by-step explanation:
8x + 12 = 2(x - 3) ← distribute the parenthesis by 2
8x + 12 = 2x - 6 ( subtract 2x from both sides )
6x + 12 = - 6 ( subtract 12 from both sides )
6x = - 18 ( divide both sides by 6 )
x = - 3
Answer:
x = -3
Step-by-step explanation:
you first distribute 2(x-3) which gives you 2x-6 so 8x+12=2x-6.
next you move the terms to the correct side so you subtract 12 from the left side and subtract 2x from the right side then move them to the other side so you end up with 8x-2x=-6-12.
then you combine like terms so you will have 6x=-18.
then divide both sides by 6 which gives you x = -3.
8x+12=2(x-3)
8x+12 = 2x-6
8x-2x = 6-12
6x = -18
x = -3
