Step-by-step explanation:

The culture will have a count of 1200 after approximately 2.77 hours. Rounded to the nearest tenth, this is 2.8 hours.

What is equations?

Equivalent equations are algebraic equations that are having identical roots or solutions.

We can solve for the time "t" by substituting the given count of 1200 into the equation and solving for "t":

[tex]1200 = 3000e^{(0.5t)}[/tex]

Divide both sides by 3000 to get:

[tex]0.4 = e^{(0.5t)}[/tex]

Take the natural logarithm of both sides to isolate the exponent:

ln(0.4) = 0.5t

Solve for "t" by dividing both sides by 0.5:

[tex]t = (ln(0.4))/0.5 = 2.77 hours[/tex]

Therefore, the culture will have a count of 1200 after approximately 2.77 hours.

[tex]1200 = 3000e^{(0.5t)}[/tex]

Divide both sides by 3000 to get:

[tex]0.4 = e^{(0.5t)}[/tex]

Take the natural logarithm of both sides to isolate the exponent:

ln(0.4) = 0.5t

Solve for "t" by dividing both sides by 0.5:

[tex]t = (ln(0.4))/0.5 = 2.77 hours[/tex]

Therefore, the culture will have a count of 1200 after approximately 2.77 hours. Rounded to the nearest tenth, this is 2.8 hours.

Using functions,

Part A: f (3) = 6(3) + 14 = 32.

g (3) = 3 + 2 = 5

Part B: (f/g) (3) will be 6.4.

The core concept of calculus in mathematics is a function. The relations are certain kinds of the functions. In mathematics, a function is a rule that produces a different result for every input x. In mathematics, a function is represented by a mapping or transformation. Letters like f, g, and h are widely used to indicate these operations. The set of all potential values that can be passed into a function while it is specified is known as the domain. The entire set of values that the function's output is capable of creating is referred to as the "range." The range of potential values for a function's outputs is known as the co-domain.

Here in the question,

f (x) = 6x + 14

g (x) = x + 2

Now we have to find for the value of x,

f (3) = 6(3) + 14 = 32.

g (3) = 3 + 2 = 5

So, f (3) = 32 and g (3) = 5.

Answer:

I can explain how to complete each of the steps you have provided.

1. Draw a point at (1, -2)

This is a simple step. Just mark a dot on your paper at the coordinates (1, -2).

2.

Draw an 8-unit long radius

Using your compass, set the radius to 8 units. Place the compass on the point you drew in step 1 and draw a circle around it, making sure that the radius is 8 units long.

3. Using a compass

Draw a circle with your point from step one as your center and the point from step two as the side: This step is already completed in step 2.

4. Using a protractor draw a 70 degree arc

Place your protractor on the center of the circle (the point you drew in step 1) and draw a 70 degree arc on the circle.

5. Draw a central angle which intercepts your arc

Use a straight edge to draw a line from the center of the circle to each endpoint of the arc you drew in step 4. This creates a central angle, which is an angle whose vertex is at the center of the circle and whose sides intercept the circle.

6. Draw an inscribed angle which intercepts a 40 degree arc

Use a straight edge to draw a line from one endpoint of the 70 degree arc to the other endpoint. Then, draw a perpendicular bisector of this line, which intersects the center of the circle. This creates a 40 degree arc on the circle. Draw a line from the center of the circle to one endpoint of the 40 degree arc, and draw a line from that endpoint to the other endpoint of the 40 degree arc. This creates an inscribed angle, which is an angle whose vertex is on the circle and whose sides intercept the circle.

7. Draw a tangent line

Choose a point on the circle that is not on the 70 degree arc. Draw a line from that point tangent to the circle.

8. Draw a secant line

Choose two points on the circle that are not on the 70 degree arc. Draw a line through those points, which intersects the circle at two points.

9. Equation of your circle

The equation of a circle with center (a,b) and radius r is (x-a)^2 + (y-b)^2 = r^2. Using the coordinates of the center from step 1 and the radius from step 2, the equation of the circle is (x-1)^2 + (y+2)^2 = 64.

The time taken by the Lamonte would be  6 hours to drive 93 miles at a speed of 15.5 miles per hour.

We can use the following formula to answer this question:

rate x time = distance

We know Lamonte drove 62 miles in four hours, so we can use that to calculate his speed:

62 miles = rate multiplied by 4 hours

When we solve for the rate, we get:

rate = 62 miles divided by 4 hours equals 15.5 miles per hour

We can now use this rate to calculate how long it would take Lamonte to drive 93 miles:

93 miles = time x rate

Substituting the recently discovered rate yields:

93 miles = 15.5 miles per hour multiplied by time

When we solve for time, we get:

time = 93 miles / 15.5 miles per hour = 6 hours

According to the solution we have come to find that, the length of the box is  [tex](V/2)^{1/3}[/tex].

what is volume?

Volume is the measure of the amount of space occupied by a three-dimensional object or region of space. It is typically measured in cubic units, such as cubic meters (m³), cubic centimeters (cm³), or cubic feet (ft³), depending on the unit of length used to measure the dimensions of the object. The formula for calculating the volume of a geometric shape depends on the shape, but generally involves multiplying the dimensions of the shape together, such as the length, width, and height of a rectangular prism, or the radius and height of a cylinder.

Let's start by defining the variables:

Let's call the height of the box "h".

The length and width are each twice as long as the height, so we can write: length = 2h and width = 2h.

The volume of the box is given as "V".

We can use the formula for the volume of a rectangular box to write:

V = length × width × height

V = (2h) × (2h) × h

V = 4h^3

Now we can solve for h in terms of V:

4h³ = V

h³ = V/4

h = [tex](V/4)^{(1/3)[/tex]

This gives us the formula for the height of the box in terms of its volume V.

If we are given the volume V and asked to find the length of the box, we can use the formula for length in terms of height:

length = 2h

length = 2(V/4[tex])^{(1/3)[/tex]

length = (2V/4[tex])^{(1/3)[/tex]

length = (V/2[tex])^{(1/3)[/tex]

So, the length of the box is  [tex](V/2)^{1/3}[/tex].

In mathematics, a function is a rule that assigns each input (or element of the domain) a unique output (or element of the range). It is a mathematical object that takes an input and produces an output based on a specified rule or set of rules. A function can be represented in different ways, such as by an equation, a graph, or a table of values. The most common notation for a function is f(x), where x is the input and f(x) is the corresponding output. Functions are used to describe relationships between quantities in various fields of mathematics and science, such as in calculus, linear algebra, statistics, physics, and engineering. They are also used in modeling real-world situations and solving problems in many areas, including finance, economics, and computer science.

The length of each leg of an isosceles right triangle with a hypotenuse of 12 inches is approximately 8.49 inches.

In an isosceles right triangle, the two legs are congruent, so let's call the length of each leg "x". Then, using the Pythagorean theorem, we can write:

[tex]x^2 + x^2 = 12^2[/tex]

Simplifying the left side, we get:

[tex]2x^2 = 144[/tex]

Dividing both sides by 2, we get:

[tex]x^2 = 72[/tex]

Taking the square root of both sides, we get:

x = sqrt(72)

We can simplify this by factoring 72 as 36 * 2:

x = sqrt(36 * 2)

Taking the square root of 36, we get:

x = 6 * sqrt(2)

So each leg of the isosceles right triangle is approximately 8.49 inches long (rounded to two decimal places).

For the given pyramid the area of the cross section is 1,307.63 mm² (option D).

What is pyramid?

A pyramid is a geometrical shape that has a polygonal base and triangular faces that meet at a common vertex, called the apex.

We can use the formula for the area of a trapezoid to find the area of the cross section. Since the slice is perpendicular to the base of the pyramid, the cross section will be a trapezoid.

The length of the top side of the trapezoid is the same as the length of one of the sides of the rectangular base of the pyramid, which is 37.8mm. The length of the bottom side of the trapezoid can be found using similar triangles:

(49.3 / 37.8) = (bottom side / height)

Simplifying, we get:

bottom side = (height x 49.3) / 37.8 = (42.1 x 49.3) / 37.8 = 54.94 mm

The height of the trapezoid is the same as the height of the pyramid, which is 42.1mm.

Using the formula for the area of a trapezoid:

area = [(top side + bottom side) x height] / 2

area = [(37.8 + 54.94) x 42.1] / 2

area = 1,307.63 mm²

Therefore, the area of the cross section is 1,307.63 mm² (option D).

To solve 2^x = 32, we need to find the value of x that satisfies the equation.

We can rewrite 32 as a power of 2 by noting that 2^5 = 32. Therefore, we have:

2^x = 2^5

Since the bases of the powers are equal, we can equate the exponents:

x = 5

So the solution to 2^x = 32 is x = 5.

To rewrite this equation in a logarithmic form, we can use the definition of logarithms:

log(base 2)32 = x

A cylinder seems to be a three-dimensional geometric shape made up of two parallel congruent circular bottoms and a curving surface linking the two bases. The bases of a cylinder are always perpendicular from its axis, which is an artificial straight line passing through the centre both of bases. The volume of a cylinder is equal to the product among its base area and height. A cylinder's volume is computed as V = r2h, within which "V" represents the volume, "r" represent the circle of the base, and "h" represents the height of the cylinder.

The volume of a cylinder is determined by the formula V = r2h, where r is the radius of the base, h is the cylinder's height, and is a mathematical constant close to 3.14.

In this situation, the radius is 2.5 cm since the base is 5 cm in diameter. The cylinder stands 10 cm tall. As a result, the volume of the cylinder is:

[tex]V = \pi(2.5 cm)^2(10 cm) (10 cm)\\V = 196.35 cm^3[/tex]
