Write the equation in standard form for the circle passing through (–
8,2) centered at the origin.
The standard form for a circle is (x - h)2 + (y - k)2 = r2, where (h, k) is the center and r is the radius. Since the radius is not given, we need to plug in the information given. Since the center is at the origin, this is the point (0, 0). Since another point on the circle is (6, 8), that is the (x, y) value. So let's plug it into the equation:
(8 - 0)2 + (8 - 0)2 = r2 --> 82 + 82 = r2 --> 100 = r2 --> 10 = r.
Since r = 10 and the center is (0, 0), the standard form equation of this circle is (x - 0)2 + (y - 0)2 = 102 or just x2 + y2 = 100.
What is radius?In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the latin radius, meaning ray but also the spoke of a chariot wheel.A radius is a straight line from the center of a circle to the circumference of a circle. The distance from the center point to any endpoint on the circle.To learn more about radius refer to:

flight of a rocket the altitude in feet attained by a model rocket t seconds into flight is given by the function h(t). find the maximum altitude (in ft) attained by the rocket. (round your answer to the nearest foot.) h(t)
the maximum altitude attained by the rocket is 300 ft (rounded to the nearest foot) with time.
To find the maximum altitude attained by the rocket, we need to find the vertex of the function h(t). We can do this by taking the derivative of the function and setting it equal to 0.
h'(t) = -32t + 300
Setting h'(t) = 0, we get
-32t + 300 = 0
32t = 300
t = 300/32
hence the time t ≈ 9.375
Now, we can substitute the value of t in the original equation h(t) to get the maximum altitude attained by the rocket.
h(9.375) = -16(9.375)2 + 300(9.375)
h(9.375) = 300 ft
Therefore, the maximum altitude attained by the rocket is 300 ft (rounded to the nearest foot).
The complete question is :

The exterior angle y of the triangle is 60 degrees.
How to find the angle of a triangle?The sum of angles in a triangle is 180 degrees. The external angle y of the triangle can be found using exterior angle theorem.
Therefore, the exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
Hence, using the exterior angle theorem,
y = 35 + 25
y = 60 degrees.

Is △XYZ equilateral, isosceles, or neither? Explain your reasoning. (Make sure to include how/why you know which of these categories the triangle falls into!)
Answer:
equilateral
Step-by-step explanation:
You want to know if the given triangle with angles marked (2x)°, (2x)°, and (3x-30)° is equilateral, isosceles, or neither.
AnglesOn the face of it, the triangle is at least isosceles, as two angles are marked identically as (2x)°.
When we apply the angle sum theorem, we find ...
(2x)° +(2x)° +(3x -30)° = 180°
7x -30 = 180
7x = 210
x = 30
2x = 2(30) = 60
3x -30 = 3(30) -30 = 60
All of the angles have the same measure, 60°, so the triangle is equilateral.
Answer:
3 equal angles = equilateral triangle
Step-by-step explanation:
the sum of the interior angles in a triangle is 180°
2x + 2x + 3x - 30 = 180
7x = 210
x = 210 : 7
x = 30
find angle Y & Z2 x 30 = 60°
find angle x3 x 30 - 30 = 60
3 equal angles = equilateral triangle

A new streaming service sent out a survey to 350 households to see who would be interested in its service. The company found that it could charge $55 per month, with a margin of error of ±1.3. If 1,000 people signed up for the service, what is the least amount of monthly revenue the company should expect?
$52,815
$53,700
$54,915
$56,300
Answer:
B) $53700-------------------------------------
The charge of $55 with error margin of ± 1.3 results in the least value of $(55 - 1.3) = $53.7 and greatest value of $(55 + 1.3) = $56.3.
If 1000 people signed up for the service, then the least total amount is:
$53.7*1000 = $53700Correct choice is B.

In kite wxyz , m∠zwy=43° and m∠xyw=12° . what is m∠wxy ? enter your answer in the box. m∠wxy = °
In kite wxyz where m∠zwy=43° and m∠xyw=12°, m∠wxy = 125°
Therefore the answer is 125.
A kite is a quadrilateral with pair of two adjacent equal sides. In the given kite wxyz, adjacent sides wx = wz and zy = xy
Here, from the figure it is evident that Δwyz is congruent to Δwyx as wx = wz, xy = zy and wy as common side by SSS congruent criteria. Thus
m∠xwy = m∠zwy = 43°
Now considering Δxwy, m∠xwy + m∠xyw + m∠wxy = 180° by angle sum property of triangle. Angle sum property of triangle states that the sum of interior angles of a triangle is 180°. Therefore,
m∠wxy = 180° - m∠xwy - m∠xyw
= 180° - 43° - 12°

A culture of bacteria has an initial population of 37000 bacteria and doubles
every 2 hours. Using the formula Pt = Po 2, where Pt is the population
after t hours, Po is the initial population, t is the time in hours and d is the
doubling time, what is the population of bacteria in the culture after 7 hours,
to the nearest whole number?
After 7 hours, the population of bacteria is obtained as 418544.
What are the rules of exponents?Some of the rules of exponents are as follows,
The product of two exponents having the same power is equal to the power of their base multiplied.
The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.
The initial population of bacteria is given as 37000.
And, the doubling time is 2 hours.
Then, the formula for the population of bacteria at t hour can be given as,
P(t) = P₀ × [tex]2^{t/2}[/tex] where P₀ is the initial population.
Substitute t = 7 and P₀ = 37000 to get,
P(7) = 37000 × [tex]2^{7/2}[/tex]
⇒ P(7) = 418544
Hence, the population of bacteria after 7 hours is 418544.
