The population of the culture at the end of 24 hours will be 1600.

To find this answer, we can use the formula for exponential growth:

P = P₀ * 2^(t/h)

Where P is the final population, P₀ is the initial population, t is the total time in hours, and h is the time it takes for the population to double.

Plugging in the given values, we get:

P = 25 * 2^(24/4)

Simplifying the exponent:

P = 25 * 2^6

Solving for P:

P = 25 * 64

P = 1600

So the population of the culture at the end of 24 hours will be 1600.

Answer: 1lb 7oz

Step-by-step explanation:

All you have to do is subtract 9lbs and 2oz by 7lbs and 11oz, which is 1lb and 7oz

(16 oz in a pound)

The answer is approximately 2.2198, which is option (b).

To evaluate log13(297) using the change-of-base formula, we can express it in terms of a logarithm with a base that we can easily calculate, such as the common logarithm (base 10) or the natural logarithm (base e).

Let's use the common logarithm:

log13(297) = log10(297) / log10(13)

We can use a calculator to find the decimal approximations of log10(297) and log10(13), and then divide them to get the final answer:

log13(297) ≈ 2.2198 (rounded to 4 decimal places)

Therefore, the answer is approximately 2.2198, which is option (b).

you assume the opposite of what you want to prove, and then show that this assumption leads to a contradiction or an absurdity. In this case, we want to prove that "if -3x + 4 < 7, then x > -1" indirectly.

Assume the opposite of what we want to prove, which is "if -3x + 4 < 7, then x ≤ -1".

Adding 3x to both sides of the inequality, we get:

4 < 3x + 7

Subtracting 7 from both sides, we get:

-3 < 3x

Dividing both sides by 3, we get:

-1 < x

This contradicts our assumption that x ≤ -1. Therefore, our assumption is false, and the original statement "if -3x + 4 < 7, then x > -1" is true. This completes the indirect proof.

The equation y=1/2x-10 is in the slope-intercept form while the other equation y=1/x is a hyperbola.

A circular cone and a plane that passes through both of the cone's nappes (see cone) connect to form a hyperbola, a two-branched open curve with a conic section.

A hyperbola is made up of two mirror images of one another that resemble two infinite bows.

These two sections are known as connected components or branches.

the hyperbola's equation denoted as (xh)2a2(yk)2b2=1).

So, the equation y=1/2x-10 is in the slope-intercept form and we know the slope which is 1/2, and b which is -10 by just observing the equation.

On the other hand, y=1/x is the hyperbola.

Two possible lengths of the bases of a trapezoid with a height of 1 foot and an area of 9 square feet are 6 feet and 12 feet, or 4 feet and 14 feet.

Let's denote the lengths of the two bases of the trapezoid as b1 and b2 (where b1 is the longer base), and the height as h = 1 foot. The formula for the area of a trapezoid is,

A = (b1 + b2) / 2 × h

Given that the area is 9 square feet, we can plug in the values and solve for one of the bases,

9 = (b1 + b2) / 2 × 1

9 = (b1 + b2) / 2

18 = b1 + b2

b2 = 18 - b1

We can substitute b2 in terms of b1 in the formula for the area to get:

9 = (b1 + (18 - b1)) / 2 × 1

9 = 18 / 2

9 = 9

This equation is true for any value of b1, which means that there are infinitely many possible trapezoids with a height of 1 foot and an area of 9 square feet. However, we can find two specific values of b1 that correspond to different trapezoids:

If we let b1 = 6 feet, then b2 = 18 - b1 = 12 feet. This trapezoid has bases of length 6 feet and 12 feet, and a height of 1 foot.

If we let b1 = 4 feet, then b2 = 18 - b1 = 14 feet. This trapezoid has bases of length 4 feet and 14 feet, and a height of 1 foot.

Using the area formula, it is obtained that Tanner has enough spray paint to cover the arrow with one can of spray paint.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

To determine if Tanner has enough spray paint for his arrow, we need to find the total area of the arrow and compare it to the coverage of one can of spray paint.

The arrow consists of a rectangle and a triangle.

The rectangle has a length of 2 feet and a width of 5 1/3 feet, so its area is -

Area of rectangle = length × width

= 2 ft × 5 1/3 ft

= 10 2/3 sq. ft.

The triangle has a base of 3 feet and a height of the difference between the width of the rectangle (5 1/3 feet) and the width of the arrow (6 feet):

Height of triangle = 6 ft - 5 1/3 ft = 2/3 ft

Area of triangle = 1/2 x base x height = 1/2 x 3 ft x 2/3 ft = 1 sq. ft.

The total area of the arrow is the sum of the area of the rectangle and the area of the triangle -

Total area of arrow = Area of rectangle + Area of triangle

Total area of arrow = 10 2/3 sq. ft. + 1 sq. ft.

Total area of arrow = 32/3 sq. ft. + 1 sq. ft.

Total area of arrow = 11 2/3 sq. ft.

Therefore, since one can of spray paint covers up to 12 square feet, Tanner has enough spray paint to cover the arrow with one can of spray paint.

what is Algebraic expression?

An Algebraic expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that can be simplified and evaluated.

To find the number of classes the Aerobics instructor teaches on Saturdays, we need to divide the total hours she teaches by the length of each class:

Total hours taught = 5 1/4 hours

Length of each class = 3/4 hour

Number of classes = (Total hours taught) / (Length of each class)

Number of classes = (5 1/4) / (3/4)

We need to convert the mixed number to an improper fraction first:

5 1/4 = (4 x 5 + 1) / 4 = 21/4

Now we can substitute the values:

Number of classes = (21/4) / (3/4)

fractions mean multiplying the first fraction by the reciprocal of the second fraction:

Number of classes = (21/4) * (4/3)

The 4 in the numerator and denominator cancel out, leaving us with:

Number of classes = 21/3

Dividing 21 by 3, we get:

Number of classes = 7

Since 40% of Jon's collection has boat stamps, that means that 20% of his total collection would be 6 stamps (40%/2  and  12/2).

All that's left to do now is get that % to 100, and we can do this by multiplying that and the number of stamps by 5.  (20%*5=100,  6*5=30)

This means that Jon has a total of 30 stamps in his collection.

Another way you could do this is simply to multiply 12 by 40%, or 0.4.
This will also give you an answer of 30 stamps.

Answer:

40%

Step-by-step explanation:

percent = part/total × 100%

percent = 88/220 × 100%

percent = 40%

Answer:

40%

Step-by-step explanation:

Our total amount of shoes to sell is 220, right? So we have to find which percentage 88 is of 220! To do this, we use division!

Instead of how you might think to do it, 220/88, we have to do the opposite!
88/220 = 0.4

0.4 is 40% of 1. Therefore 88 is 40% of 220.

The shortest distance from a point to a line can be found by using the formula:
d = |Ax + By + C| / √(A² + B²)

where A, B, and C are the coefficients of the line equation and x and y are the coordinates of the point.

In this case, A = 2, B = 3, C = -1, x = 6, and y = 5.
Plugging these values into the formula, we get:
d = |(2)(6) + (3)(5) - 1| / √(2² + 3²)
d = |17| / √(13)
d = 17 / √(13)
d = √(13) * 17 / 13
d = √(13) * √(13) / √(13)
d = √(13)

The first derivative of a function equals zero on an interval, the function has a relative extremum on that interval.

Answer: The interval on which the function g(x) increases and decreases.The g function's vertex is at (-5, 2), and we need to figure out where the function increases and decreases. When a function has a vertex, it always opens up or down. As a result, the vertex serves as the function's minimum or maximum point.Given the above, we can assume that g(x) decreases to the left of x = -5 and increases to the right of x = -5. If we want to be more precise about the intervals, we can use the first derivative test. The first derivative of g(x) is as follows:g'(x) = 3x + 15The first derivative test states that if the first derivative of a function is greater than zero on an interval, the function is increasing on that interval. If the first derivative of a function is less than zero on an interval, the function is decreasing on that interval. Finally, if the first derivative of a function equals zero on an interval, the function has a relative extremum on that interval. We now need to find where g'(x) > 0 and where g'(x) < 0.3x + 15 > 0 => x > -5g(x) is increasing on the interval (-5, ∞)3x + 15 < 0 => x < -5g(x) is decreasing on the interval (-∞, -5)

The value of (g times f)(x) is 6x² + x - 2. So correct is C.

The input values of a function are called the domain, and the output values are called the range. The domain can be any set of values, but each input value must have a unique corresponding output value. If there are multiple input values that produce the same output value, the function is not considered to be well-defined. Functions are used to model a wide range of phenomena in many different fields, including science, engineering, and economics. They are also used in calculus to study rates of change and slopes of curves.

Overall, functions are a fundamental concept in mathematics, and have many practical applications in the real world.

To find g(x) times f(x), we need to multiply the two functions together.

(g times f)(x) = g(x) * f(x)

First, we need to find g(f(x)):

g(f(x)) = g(3x+2) = 2(3x+2) - 1 = 6x + 3

Now we can substitute this into the expression for (g times f)(x):

(g times f)(x) = g(x) * f(x) = (2x-1) * (3x+2)

Using the distributive property, we get:

(g times f)(x) = 6x² + 4x - 3x - 2 = 6x² + x - 2

Therefore, (g times f)(x) = 6x² + x - 2.
