Answer:
Step-by-step explanation:
he correct answer for the domain of function p(x) is:
Domain: [1, ∞)
This means that x can take any value greater than or equal to 1, including 1 itself. The square root function (√x) is defined for non-negative real numbers, so x must be greater than or equal to 0. In this case, since we have √x - 1 in the function, x must be greater than or equal to 1 to avoid a negative value under the square root. Additionally, there are no other restrictions on the domain, so any value of x greater than or equal to 1 is allowed.

The equation of the circle with a center at (-4, 6) and a point on the circumference at (-2, 9) is (x + 4)² + (y - 6)² = 13.
Given:
Center of the circle: (-4, 6)
Point on the circumference: (-2, 9)
The center of the circle (h, k) is given as (-4, 6), which means h = -4 and k = 6.
The formula for the distance between the center and the point on the circumference can be used to determine the radius (r).
The formula for distance is provided by:
d = √((x₂ - x₁)² + (y₂ - y₁)²)
where (x₁, y₁) is the center (-4, 6), and (x₂, y₂) is the point on the circumference (-2, 9).
Putting in the values:
d = √((-2 - (-4))² + (9 - 6)²)
= √((2)² + (3)²)
= √(4 + 9)
= √13
So, the radius (r) is √13.
Now, we can substitute the values of h, k, and r into the general equation of the circle:
(x - h)² + (y - k)² = r²
(x - (-4))² + (y - 6)² = (√13)²
(x + 4)² + (y - 6)² = 13
Therefore, the equation of the circle is (x + 4)² + (y - 6)² = 13.

A model rocket is launched from ground level. It’s flight path is modeled by the following equation Y= -16t^2+160t where h is the height of the rocket above the ground in feet and t is the time after the launch in seconds. what is the rocket’s maximum height? when did the rocket reach the maximum height?
The rocket's maximum height is 800 feet. It reached its maximum height at 5 seconds after launch.
To solve this problem, we need to find the vertex of the parabola represented by the equation Y= -16t^2+160t. The vertex of a parabola is the point where the parabola changes direction, from increasing to decreasing or vice versa.
The vertex of the parabola is given by the following formula:
(-b/2a, c - b^2/4a)
In this case, the value of b is 160 and the value of a is -16. Plugging these values into the formula, we get the following:
(-160/2(-16), 800 - 160^2/4(-16))
(5, 800)
Therefore, the rocket reached its maximum height at 5 seconds after launch. The maximum height is 800 feet.

A triangle has vertices A(-4, 0),
B(4, 8), and C(8, - 12), and the following is true
Angle A " B" C " = D 3/2(D 1/2
(Angle ABC)
What is the perimeter of Angle
A" B"C"?
The perimeter of triangle A"B"C" is found as 43.78.
How do we calculate?
We first determine length of each side:
The distance formula has that :
AB = √[(4 - (-4))² + (8 - 0)²]
= √128
= 8√2
BC = √[(8 - 4)² + (-12 - 8)²]
= √320
= 8√5
CA = √[(-4 - 8)² + (0 - (-12))^²]
= √320
= 8√5
cos(ABC) = (AB² + BC² - CA²) / (2 * AB * BC)
cos(ABC) = (128 + 320 - 320) / (2 * 8√2 * 8√5)
cos(ABC) = 1 / (4√2)
ABC = [tex]cos^{-1}[/tex](1 / (4√2))
ABC = 78.46°
A"B" = AB = 8√2
B"C" = BC = 8√5
C"A" = CA = 8√5
We then find the perimeter of triangle A"B"C" is:
A"B" + B"C" + C"A"
= 8√2 + 8√5 + 8√5
= 8√2 + 16√5
= 43.78

directions say to use one cup per every 20 square feet? how many cups of fertilizer should she use? enter your answer as a decimal, rounded to the nearest half cup
Mrs. Tilmos should use 8 1/2 cups of fertilizer for her triangle garden.
To answer the question, we must first calculate the area of Mrs. Tilmos' triangle garden. We can do this using the equation for the area of a triangle (A=1/2 × b × h). In this equation, b is the base and h is the height.
For this garden, the base (b) is 13 feet and the height (h) is twice the base, so h=2 × b or h=26 feet. Using the equation, we can calculate that the area of the garden is:
A = 1/2 × b × h
A = 1/2 × 13 × 26
A = 169 square feet
Now that we have the area of the garden, we can calculate how many cups of fertilizer to use. We know that the fertilizer's directions say to use 1 cup per every 20 square feet, so we have to divide 169 by 20.
169 / 20 = 8.45
We can round this result up to 8 1/2 cups of fertilizer to use.
Therefore, Mrs. Tilmos should use 8 1/2 cups of fertilizer for her triangle garden.

Two triangles can be formed using the given measurements. Solve both triangles.
A = 59°, a = 13, b = 14
The value of the angles are::
67.4°, C = 53.6°, c = 12.2; B = 112.6°, C = 8.4°, c = 2.2
Here, we have,
angle A = 59° and sides a = 13, b = 14.
Lets find remaining angles are B and C and the remaining side c.
Law of sines : a/sinA = b/sinB ⇒ sinB = (b*sinA)/a
sinB = (14*sin59o)/13 = (14*0.857167)/13 ≅ 0.923
B ≅ sin-1(0.923) ≅ 67.384.
There are two triangles, B₁ = 67.4 and B₂ = 180 - 67.4 = 112.6
find the angle c for B₁ = 67.4
A+ B +C = 180.
Angle C = 180 - (59 + 67.4) = 53.6.
Law of sines : b/sinB = c/sinC ⇒ c = b*sinC/sinB
c = (14)*sin(53.6)/sin(67.4) = (14)*(0.805)/(0.923) = 12.21.
now, we have,
find the angle c for B₂ = 112.6
A+ B +C = 180.
Angle C = 180 - (59 + 112.6) = 8.4.
Law of sines : b/sinB = c/sinC ⇒ c = b*sinC/sinB
c = (14)*sin(8.4)/sin(112.6) = (14)*(0.146)/(0.9232) = 2.27.

In.a two - digit number, the units digit is twice the tens digit. If the number is doubled, it will be 12 more than the number reversed. Find the number
The number is 48.
Let's represent the two-digit number as 10x + y, where x is the tens digit and y is the units digit.
According to the given information, the units digit is twice the tens digit. So we have the equation:
y = 2x
If the number is doubled, it will be 12 more than the number reversed. When we double the number, we get 2(10x + y), and the number reversed is 10y + x.
Therefore, we can write the equation as:
2(10x + y) = 10y + x + 12
Simplifying this equation, we get:
20x + 2y = 10y + x + 12
19x = 8y + 12
19x - 8y = 12
We have two equations now:
y = 2x
19x - 8y = 12
Substituting the value of y from the first equation into the second equation, we get:
19x - 8(2x) = 12
19x - 16x = 12
3x = 12
x = 4
Now we can substitute the value of x back into the first equation to find y:

2. The total dosage of medication required for the patient is 13.608 mg. [tex](0.5 mg/kg \times 27.216 kg = 13.608 mg)[/tex]
3. The patient should be administered 1.3608 mL of the stock medication. (13.608 mg / 10 mg/mL = 1.3608 mL)
To calculate the necessary values based on the given information, let's follow the steps below:
Determine the weight of the patient in kilograms:
Given that the patient weighs 60 lb, we can convert this to kilograms using the conversion factor of 1 lb = 0.4536 kg.
Weight (in kg)[tex]= 60 lb \times 0.4536 kg/lb = 27.216 kg.[/tex]
Calculate the total dosage of medication required for the patient:
The medication order is 0.5 mg/kg, and the patient weighs 27.216 kg.
Total dosage [tex]= 0.5 mg/kg \times 27.216 kg = 13.608 mg.[/tex]
Determine the amount of stock medication required in milliliters (mL):
The stock medication is available in a concentration of 10 mg/mL.
To find the volume required, we need to divide the total dosage by the concentration of the stock medication.
Volume (in mL) = Total dosage (in mg) / Concentration (in mg/mL) = 13.608 mg / 10 mg/mL = 1.3608 mL.
Therefore, based on the given information, the weight of the patient is 27.216 kilograms, the total dosage of medication required is 13.608 milligrams, and 1.3608 milliliters of the stock medication should be administered to the patient.
Please note that when administering medication, it is crucial to follow the guidance of a healthcare professional and consider other factors such as the specific medication instructions, patient's condition, and any allergies or contraindications.

, shift to the left 1 unit, and shift upward 3 units.
(4.2) f(x) = (2) √
x; reflect in the x−axis, shift 1 units upwards
(4.3) f(x) = (2) √
x; reflect in the y−axis, shift 2 units downw
The final transformed graphs are 1) f'(x) = (1/2)|x + 1| + 3, 2) f'(x) = -√x + 1 and 3) f'(x) = -√x - 2.
1. Break down the transformations step by step.
Start with the function f(x) = |x|.
a. Shrink vertically by a factor of 1/2: Multiply the function by 1/2.
g(x) = (1/2)|x|.
b. Shift to the left 1 unit: Replace x with (x + 1).
h(x) = (1/2)|x + 1|.
c. Shift upward 3 units: Add 3 to the function.
f'(x) = (1/2)|x + 1| + 3.
Therefore, the equation for the final transformed graph is f'(x) = (1/2)|x + 1| + 3.
2. Start with the function f(x) = √x.
a. Reflect in the x-axis: Multiply the function by -1.
g(x) = -√x.
b. Shift 1 unit upward: Add 1 to the function.
f'(x) = -√x + 1.
Therefore, the equation for the final transformed graph is f'(x) = -√x + 1.
3. Start with the function f(x) = √x.
a. Reflect in the y-axis: Multiply the function by -1.
g(x) = -√x.
b. Shift 2 units down: Subtract 2 from the function.
f'(x) = -√x - 2.
Therefore, the equation for the final transformed graph is f'(x) = -√x - 2.

Answer:
Step-by-step explanation:
Ok so, as given in the table, the cost of the 3rd tank is 800$, we can thus determine the cost of 1 cubic inch for a tank and use that to determine the cost of the other tanks.
[tex]volume =L\times W\times H\\=24\times 24\times 24\\=13824 in^3[/tex]
thus, to compute the cost of one cubic inch, we can divide the cost by the volume of the 3rd tank (in cubic inches)
[tex]\frac{800}{13824}=0.0579[/tex] [tex]usd/in^3[/tex]
now, we can determine the dimensions of the second tank that will make it cost 150$
[tex]0.0579\times 18\times W\times 24=150[/tex]
[tex]W=\frac{150}{0.0579\times 18\times 24} =6 in.[/tex]
Now to determine the cost of the first tank, we can multiply its volume by the cost per cubic inch:
[tex]cost=0.0579\times36\times 36\times 36=2700[/tex]$
As of question B, the cost will increase as the width increases.
For Question C, we can find the volume of the sphere by the formula:
[tex]volume=\frac{4}{3}\pi r^3 =\frac{4}{3}\pi \times 24^3=57905 in^3[/tex]
To find the cost of that tank, we just multiply its volume by the cost per unit volume:
[tex]cost=57905\times 0.0579=3352[/tex]$ (roughly)
Find the average rate of change of g(x) = x over the interval
[-9, -2].
Write your answer as an integer, fraction, or decimal rounded to
nearest tenth. Simplify any fractions.
The average rate of change of [tex]\(g(x) = x\)[/tex] over the interval [tex]\([-9, -2]\) is 1.[/tex]
To find the average rate of change of a function over an interval, we calculate the difference in the function values at the endpoints of the interval and divide it by the difference in the corresponding x-values.
In this case, the function [tex]\(g(x) = x\)[/tex] and the interval is [tex]\([-9, -2]\)[/tex]. We can determine the average rate of change as follows:
[tex]\[ \text{Average rate of change} = \frac{g(-2) - g(-9)}{-2 - (-9)} \][/tex]
By substituting the function values, we get:
[tex]\[ \text{Average rate of change} = \frac{-2 - (-9)}{-2 - (-9)} \][/tex]
Simplifying the numerator and denominator, we have:
[tex]\[ \text{Average rate of change} = \frac{7}{7} = 1 \][/tex]
Therefore, the average rate of change of [tex]\(g(x) = x\)[/tex] over the interval [tex]\([-9, -2]\)[/tex] is [tex]1[/tex].

=b as a result of completing the square for the following equation?
x^2+22x=8x-53
By completing squares we will get the expression:
(x + 7)² = -4
How to complete squares in a quadratic equation?Here we have the quadratic equation:
x² + 22x = 8x - 53
First, move all the terms to the left side, then we will get:
x² + 22x - 8x + 53 = 0
x² + 14x + 53 =0
Now, remember the perfect square trinomial:
(a + b)² = a² + 2ab + b²
Then we can rewrite our expression as:
x² + 2*7*x + 53 =0
Now we can add and subtract 7², then we will get.
x² + 2*7*x + 7² - 7² + 53 =0
(x + 7)² - 7² + 53 = 0
(x + 7)² - 49 + 53 = 0
(x + 7)² + 4 = 0
(x + 7)² = -4
That is the expression we wanted.

Start with the top figure. Which transformation was used to create the pattern?
translation
rotation
reflection
glide reflection
The transformation used to create the pattern in the top figure is reflection.
A reflection is a transformation that flips an object over a line, called the line of reflection. It produces a mirror image of the original object. In the case of the pattern in the top figure, we can observe that the pattern is symmetric about a specific line of reflection.
To determine if a reflection was used, we examine the pattern for mirror symmetry. Mirror symmetry means that one half of the pattern is a reflection of the other half. In the top figure, if we were to fold the pattern along a vertical line, the two halves would align perfectly, indicating mirror symmetry.
This mirror symmetry suggests that a reflection has been applied to create the pattern. Each shape in the pattern appears to have been reflected across the line of reflection to create its corresponding mirrored shape.
Other transformations such as translation, rotation, and glide reflection do not exhibit the same mirror symmetry as a reflection. A translation involves shifting an object without changing its orientation, a rotation involves rotating an object around a fixed point, and a glide reflection is a combination of a translation and a reflection.
In conclusion, based on the mirror symmetry observed in the top figure's pattern, the transformation used to create the pattern is a reflection.
