The growth rate of bacteria in a culture is not specified, so assuming it is exponential, the number of bacteria present after 2 hours will be approximately 1.8 x 10^8.

To solve this problem, we can use the exponential growth formula: N(t) = N0 * e^(rt), where N(t) is the number of bacteria at time t, N0 is the initial number of bacteria, r is the growth rate, and e is the base of the natural logarithm. First, we need to find the growth rate, r. We can use the initial and final number of bacteria and the time interval to do this.

N(t) = N0 * e^(rt)

171 = 38 * e^(49r)

ln(171/38) = 49r

r = ln(171/38)/49

r ≈ 0.069 Now we can use the formula to find N(120) (i.e., the number of bacteria after 2 hours, or 120 minutes):

N(120) = 38 * e^(0.069 * 120)

N(120) ≈ 1.8 x 10^8 Therefore, approximately 1.8 x 10^8 bacteria will be present in the culture after 2 hours.

The third side of the right angle triangle is x = 15 ft.

What is right angle triangle?

A right triangle is a triangle with one angle at a right angle, meaning that two of its sides are perpendicular. It is also known as a right-angled triangle, an orthogonal triangle, or more commonly as a rectangled triangle. Trigonometry's foundation is the right triangle's relationship between its sides and other angles.

We have to find the measure of third side of given right triangle.

The two sides of right triangle are 9 ft and 12 ft.

Let the side of third side is x.

By using the Pythagoras theorem,

(9)^2 + (12)^2 = x^2

       81 + 144 = x^2

             225 = x^2

                  x = 15

Hence, the third side of the right angle triangle is x = 15 ft.

4x - 5y = -9

-4x + y = -7

Step 1

Eliminate variable x

Different sign eliminate x and add.

-5y + y = -9 + (-7)

- 4y = -9 - 7

- 4y = -16

y = -16/-4

y = 4

Step 2

Substitute y in any equation and find x.

-4x + y = -7

-4x + 4 = -7

-4x = -7 - 4

-4x = -11

x = -11/-4

x = 11/4

X = 11/4 Y = 4

Bryant Industries uses forecasting to estimate the number of orders that will be placed by their customers. The table below gives the sales figures for the last four months.Month2345Sales92491942004There are different forecasting techniques used by companies like Bryant Industries to predict future sales.

One of the most widely used methods is the time-series method. This method is particularly useful when the demand for a product or service changes over time and when there are no external factors that affect the sales. In this case, we can use a time-series method called the moving average to estimate future sales. The moving average is a time-series method that uses the average of past sales data to estimate future sales. It is particularly useful when there are no external factors that affect the sales. In this case, we can use a 3-month moving average to estimate future sales. The 3-month moving average is calculated as follows: (924 + 919 + 420) / 3 = 754.33. This means that we can expect sales of around 754 units next month. The moving average method is easy to use and is a good way to get a quick estimate of future sales. However, it has some limitations. For example, it does not take into account external factors that may affect sales, such as changes in the economy or in consumer behavior.

In conclusion, Bryant Industries can use the moving average method to estimate future sales. However, they should also consider other factors that may affect sales, such as changes in the economy or in consumer behavior. By doing so, they can make more accurate forecasts and improve their overall performance.

answer for -2x+3y=6: x=3/2y-3

pls give brainliest

Answer:

There are infinitely many solutions.

Step-by-step explanation:

There are infinitely many solutions because if you solve the equations, you will find that both of the equations are actually the same, so there is infinitely many solutions.

Showing that both equations are equal:  y=2/3x+2       -2x+3y=6

y=2/3x+2  Multiply by 3 on both sides

3y=2x+6 Rearrange (-2x on both sides)

3y-2x=6 More rearrangement

-2x+3y=6 Now, if you look back at the second equation, you will see that they are both the same.

A multiple regression analysis was performed to predict a team's points in the National Football League (NFL) based on rushing yards (x1), passing yards (x2), and first downs (x3). The estimated regression equation was obtained as the model for predicting points.

In the multiple regression analysis, the goal is to establish a relationship between the dependent variable (points) and multiple predictor variables (rushing yards, passing yards, and first downs). The estimated regression equation provides a mathematical representation of this relationship. The equation takes the form:

Points = b0 + b1(x1) + b2(x2) + b3(x3)

where b0 is the intercept term, and b1, b2, and b3 are the coefficients associated with the predictor variables x1, x2, and x3, respectively. These coefficients represent the estimated effect of each predictor variable on the points scored by a team.

By utilizing the estimated regression equation, one can input the values of rushing yards, passing yards, and first downs for a particular team and calculate the predicted points for that team based on the model. This analysis allows for making predictions and understanding the relationships between the predictor variables and the dependent variable in the context of NFL games.

The equation to find the cost of each pair of shorts is 175 = 75 + 5x where each short cost $20

Cost of jackets= $75

Number of shorts= 5

Cost of each short = x

Total amount Jim spent= $175

Total amount Jim spent = Cost of jackets + (Number of shorts × Cost of each short)

175 = 75 + 5x

subtract 75 from both sides

175 - 75 = 5x

100 = 5x

divide both sides by 5

x = 100/5

x = $20

a) The domain of f(x) is all real numbers. b) The limit of f(x) as x approaches 0 is 2, and the limit of f(x+2) as x approaches 1 is 9.c) f(-3) is undefined, and f(x) = x² + 4x + 2.

a) The domain of f(x) is the set of all values of x for which the function is defined. Since f(x) is a quadratic polynomial, it is defined for all real numbers. Therefore, the domain of f(x) is (-∞, ∞), or all real numbers.

b) To find the limits, we evaluate the function as x approaches the given values:

lim f(x) as x approaches 0:

Substituting x = 0 into the function f(x) = x² + 4x + 2, we get f(0) = 0² + 4(0) + 2 = 2. Therefore, the limit of f(x) as x approaches 0 is 2.

lim f(x+2) as x approaches 1:

Substituting x+2 for x in the function, we have f(x+2) = (x+2)² + 4(x+2) + 2. Plugging in x = 1, we get f(1+2) = (1+2)² + 4(1+2) + 2 = 3² + 4(3) + 2 = 9 + 12 + 2 = 23. Therefore, the limit of f(x+2) as x approaches 1 is 23.

c) To find f(-3), we substitute x = -3 into the function: f(-3) = (-3)² + 4(-3) + 2 = 9 - 12 + 2 = -1. Therefore, f(-3) is equal to -1.

In conclusion, a) the domain of f(x) is all real numbers, b) the limit of f(x) as x approaches 0 is 2, and the limit of f(x+2) as x approaches 1 is 9, and c) f(-3) is -1. The function f(x) is defined as f(x) = x² + 4x + 2.

To find the series solution for the differential equation y'' + 2xy' + 2y = 0, we can assume a power series solution of the form:

Now, substitute y(x), y'(x), and y''(x) into the differential equation:

∑(n=0 to ∞) aₙn(n-1) xⁿ⁻² + 2x ∑(n=0 to ∞) aₙn xⁿ⁻¹ + 2 ∑(n=0 to ∞) aₙxⁿ = 0

We can simplify this equation by combining the terms with the same powers of x. Let's manipulate the equation step by step:

We can combine the three summations into a single summation:

∑(n=0 to ∞) (aₙ₊₂(n+1)n + 2aₙ₊₁ + 2aₙ) xⁿ = 0

For complementary angles A and B with the measure of m∠A =  6X -15 and m∠B = 5X +6 then m∠A = 39° and m∠B=51°.

As given in the question,

Given relation between angle A and B is :

Both are complementary angles

Measure of m∠A =  6X -15 and m∠B = 5X +6

As per the given condition we have,

m∠A + m∠B = 90°

⇒ ( 6x -15 ) + ( 5x + 6 ) = 90°

Collect the like terms we get,

6x + 5x -15 + 6 = 90°

⇒ 11x -9 = 90°

⇒ 11x = 99°

⇒ x = 9°

Substitute the value of x in m∠A and m∠B

m∠A = 6x -15

        = 6(9) -15

        = 39°

m∠B = 5x +6

        =5(9)+ 6

        = 51°

Therefore, for complementary angles A and B with the measure of m∠A =  6X -15 and m∠B = 5X +6 then m∠A = 39° and m∠B=51°.
