The age of Mikhail's is 24 years old.
To find Mikhail's age, let's denote Mikhail's age as ( x ) and Gabrielle's age as ( 2x ) (since Gabrielle is twice as old as Mikhail). We know the sum of their ages is 72. We can set up an equation to represent this information:
[tex]\[ x + 2x = 72 \][/tex]
Step 1: Combine like terms
Combine the (x) terms on the left side of the equation:
[tex]\[ x + 2x = 3x \][/tex]
So, the equation simplifies to:
[tex]\[ 3x = 72 \][/tex]
Step 2: Solve for ( x )
To find the value of ( x ), divide both sides of the equation by 3:
[tex]\[ x = \frac{72}{3} \][/tex]
[tex]\[ x = 24 \][/tex]
Therefore, Mikhail's age is 24 years old.
Mikhail's age is 24. Gabrielle is 48.
Let's solve it step by step:
1. Let's represent Gabrielle's age as [tex]\( G \)[/tex] and Mikhail's age as [tex]\( M \)[/tex].
2. According to the given information, Gabrielle's age is two times Mikhail's age, so we can express this as an equation:
[tex]\[ G = 2M \][/tex]
3. We also know that the sum of their ages is 72, which can be expressed as another equation:
[tex]\[ G + M = 72 \][/tex]
4. Now, we have a system of two equations:
[tex]\[ G = 2M \][/tex]
[tex]\[ G + M = 72 \][/tex]
5. Substitute the value of [tex]\( G \)[/tex] from the first equation into the second equation:
[tex]\[ 2M + M = 72 \][/tex]
[tex]\[ 3M = 72 \][/tex]
6. Divide both sides by 3 to solve for [tex]\( M \)[/tex]:
[tex]\[ M = \frac{72}{3} \][/tex]
[tex]\[ M = 24 \][/tex]
7. So, Mikhail's age is 24 years.
Now, to verify, we can find Gabrielle's age using the first equation:
[tex]\[ G = 2M \][/tex]
[tex]\[ G = 2(24) \][/tex]
[tex]\[ G = 48 \][/tex]
Gabrielle's age is indeed 48 years.
So, to recap, Mikhail's age is 24 years.

A health clinic has 3 1/2 quarts and 1 gallon of antiseptic wash in inventory.How many fluid ounces of antiseptic wash do they have on hand?
Answer:
240 fluid ounces
Step-by-step explanation:
A health clinic has [tex]3\frac{1}{2}[/tex] quarts and 1 gallon of antiseptic wash in inventory.
We have to convert the unit of fluid in ounces.
1 quart = 32 ounces
1 gallon = 128 ounces
[tex]3\frac{1}{2}[/tex] quarts = [tex]3\frac{1}{2}[/tex] × 32 = 112 ounces
Total fluid of antiseptic wash = 112 + 128 = 240 fluid ounces
They have 240 fluid ounces of antiseptic wash in hand.
The equation of motion for a weight suspended from a particular spring is given by p(t)=2sint3+5cost3p(t)=2sint3+5cost3, where p(t)p(t) is the displacement from the equilibrium position in centimeters, and tt is the time elapsed in seconds. at what time does the weight first reach the equilibrium position?
Final answer:
To find the time at which the weight first reaches the equilibrium position, set the equation of motion equal to zero and solve for t.
Explanation:
The equation of motion for the weight suspended from the spring is given by p(t) = 2sin(t/3) + 5cos(t/3), where p(t) is the displacement from the equilibrium position in centimeters and t is the time elapsed in seconds. The weight first reaches the equilibrium position when the displacement p(t) equals zero. To find the time at which this occurs, we set the equation equal to zero and solve for t.
2sin(t/3) + 5cos(t/3) = 0
Using trigonometric identities, we can rewrite the equation as:
2sin(t/3) = -5cos(t/3)
Dividing both sides by cos(t/3), we get:
2tan(t/3) = -5
Therefore, to find the time at which the weight first reaches the equilibrium position, we need to solve the equation 2tan(t/3) = -5 for t.

Compare the functions f(x) = x5 and g(x) = 5x by graphing both functions in several viewing rectangles. find all points of intersection of the graphs correct to one decimal place. (enter your answers as a comma-separated list. round any decimal answers to one decimal place.)
To compare the functions f(x) = x^5 and g(x) = 5x, graph both functions and find their points of intersection.
Explanation:To compare the functions f(x) = x^5 and g(x) = 5x, we can graph both functions in several viewing rectangles. By finding the points of intersection of the graphs, we can compare their values at those points.
Start by graphing the function f(x) = x^5 using a graphing calculator or software. This will give us a curve with a steep increase as x gets larger.Next, graph the function g(x) = 5x in the same viewing rectangle as f(x). This will give us a straight line that increases more gradually as x gets larger.Identify the points of intersection between the graphs of f(x) and g(x). These are the x-values at which the two functions have the same y-value. Round these x-values to one decimal place and list them as the points of intersection.What is the constant high temperature at which organisms are able to live in thermal vents and volcanoes?

G the base of a solid is the circle x2 + y2 = 9. cross sections of the solid perpendicular to the x-axis are equilateral triangles. what is the volume, in cubic units, of the solid
Final answer:
To find the volume of the solid, we can use the formula V = A * h, where A is the area of the base and h is the perpendicular height. Given that the base is a circle and the cross sections of the solid are equilateral triangles, we can calculate the volume by integrating the expression for the area of the cross section from -3 to 3.
Explanation:
To find the volume of the solid, we can use the formula V = A * h, where A is the area of the base and h is the perpendicular height.
Given that the base is a circle with equation x^2 + y^2 = 9, we can determine the radius of the circle to be 3 units.
The cross sections of the solid perpendicular to the x-axis form equilateral triangles. The side length of an equilateral triangle is equal to the radius of the circle, which is 3 units. Since the height of each elemental cylinder is 2y, and the height of an equilateral triangle is h = √(3^2 - (3/2)^2) = √(9 - 9/4) = √(36/4 - 9/4) = √(27/4), the volume of each elemental cylinder is 4π(3^2 - x^2)^(1/2) dx = 4π(27 - 4x^2)^(1/2) dx.
To find the total volume of the solid, we integrate the expression 4π(27 - 4x^2)^(1/2)dx from x = -3 to x = 3.
∫(4π(27 - 4x^2)^(1/2)dx from -3 to 3 = 4π∫(27 - 4x^2)^(1/2)dx from -3 to 3 = 4π∫(27 - 4x^2)^(1/2)dx from -3 to 3 = 4π∫(27 - 4x^2)^(1/2)dx from -3 to 3 = 4π(3^3/3 - (-3)^3/3) = 36π units^3.
