A culture of bacteria has an initial population of 37000 bacteria and doubles every 2 hours. Using the formula P↓t=P↓0 ⋅2↑d/t, where P↓t is the population after t hours, P↓0 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?

The required line representing the equation part of the constraint is go through (0, 4) and (7,0).

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

The line representing the equation 7x1 + 4x2 = 28 is a boundary line that separates the feasible solutions from the infeasible solutions in a linear programming problem.

The line passes through two points, which can be determined by substituting the x1 and x2 values into the equation. By substituting the values (4,0) and (7,0) into the equation, we can see that both points satisfy the constraint.

This means that any point on the line also satisfies the constraint, and any point above or to the right of the line would be infeasible as they would not meet the requirement of the constraint.

Understanding the position and shape of the constraint lines is important in solving linear programming problems and finding the optimal solution.

cos(θ) = 20/29,

csc(θ) = 29/21,

sec(θ) = 29/20,

cot(θ) = 20/21.

In a nutshell, trigonometric functions, also referred to as circular functions, are the functions of a triangle's angle. This suggests that these trig functions provide the relationship between a triangle's angles and sides. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.

Given that,

tan (θ) = - 21 / 20

We can infer from the value that the triangle's two legs are 21 and 20, respectively.

Using the Pythagorean theorem, we can:

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex](21)^{2} + (20)^{2} = c^{2}[/tex]

The number of associates assigned to the case and the number of partners assigned to the case is 6 and 4.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

Given that,

The daily rate charged to the client for each associate is $600 and the daily rate for each partner is $1100.

The law firm assigned a total of 10 lawyers to the case and was able to charge the client $8000 per day for these lawyers' services.

Here we assume number of associate be x and no of partners be y.

Based on the above information, the calculation is as follows:

x +  y = 10

x = 10 - y

Now put the value of x in the below equation

600x + 1100y = 8,000

600 (10 - y) + 1100y = 8000

6000 - 600y  + 1100y = 8000

2000 = 500y

y = 4

So x = 10 - 4

= 6

Hence, The number of associates assigned to the case and the number of partners assigned to the case is 6 and 4.

The amount of tip will be $6.36. And the total amount of the restaurant bill with the tip will be $48.76.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

One way to compute a 15% tip for a bill is to multiply it by 0.15. A restaurant bill was $42.40.

Then the amount of tip is given as,

Tip amount = $42.40 x 0.15

Tip amount = $6.36

The total amount is given as,

Total amount = $42.40 + $6.36

Total amount = $48.76

The amount of tip will be $6.36. And the total amount of the restaurant bill with the tip will be $48.76.

The sampled students were asked how many hours they spend per week using any university computer lab. Let represent the average hours per week spent in any university computer lab by the 45 biology majors, and let 1, represent the average hours per week spent in any university computer lab by the 55 business majors. Which of the following Is the best explanation for why the sampling distribution of can be modeled with a normal distrlbution? A) The two sample standard deviations are assumed to be equal_

The standard deviation of a data set provides information about the spread or dispersion of the data around the mean.

It helps to determine the percentage of normal distribution in the data. If the standard deviation is small, it indicates that the data is tightly clustered around the mean and a high percentage of the data falls within a few standard deviations of the mean. On the other hand, if the standard deviation is large, it suggests that the data is more spread out and a smaller percentage of the data falls within a few standard deviations of the mean.

In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. So, the standard deviation provides insight into the proportion of data points that are close to the mean, and therefore, the shape of the distribution.

The value of the exponential function is g ( x ) = ( 1/4 )ˣ  and the graph is plotted

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

The area of triangle cde with altitude ef is 8 square units. This is calculated by finding the height from point "e" to "f", and the base from point "c" to "d", and then using the formula: Area = (base * height) / 2. The answer is 8 square units.

The area of a triangle can be calculated using the formula:

Area = (Base x Height) / 2

To find the height, we need to find the distance between the point where the altitude intersects the base (in this case, point "f" on the y-coordinate of point "e"), and the other two points of the triangle (in this case, "c" and "d").

The equation for a line in the form y = mx + b can be used to find the y-coordinate of point "f". Using the coordinates of points "c" and "e", the slope can be found by:

m = (3 - (-2)) / (2 - 3) = -1

The y-intercept can be found using the coordinates of point "c" and the slope:

b = -2 - (3 * -1) = 1

So the equation of the line that passes through points "c" and "e" is:

y = -x + 1

We can now use this equation to find the y-coordinate of point "f":

y = -x + 1

y = -0 + 1

y = 1

The height of the triangle is now the distance between points "e" and "f":

height = |3 - 1| = 2

The base of the triangle can be found by taking the distance between points "c" and "d":

base = |(-1) - (3)| = 4

So the area of the triangle is:

Area = (base * height) / 2

Area = (4 * 2) / 2

Area = 8

The area of the triangle is 8 square units.

Hi my dream princess

A regular polygon with an interior angle of 172° has the following characteristics:

Exterior angle: 360° / number of sides - interior angle.

Number of sides: 360° / exterior angle.

Using this information, we can find the exterior angle and the number of sides:

Exterior angle: 360° / number of sides - 172°.

Number of sides: 360° / (360° / number of sides - 172°).

Solving for the number of sides, we have:

Number of sides: 360° / (360° / number of sides - 172°)

= 360° / (360° / number of sides) - 172° / (360° / number of sides)

= number of sides - 172° / (360° / number of sides)

= number of sides (1 - 172° / 360°)

= number of sides * 188° / 360°.

Since we have a fraction involving a fraction, we can simplify:

Number of sides = number of sides * 188° / 360°

= number of sides * 47° / 90°

= number of sides * 47 / 90.

Since 47 and 90 are both divisible by 47, we can simplify further:

Number of sides = number of sides * 47 / 90

= number of sides * 1 / 2.

Therefore, the regular polygon has 2 sides and each exterior angle is 180°. The polygon is an isosceles triangle.
