Answer 2

Answer:

Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).

Step-by-step explanation:

To factor the quadratic expression 3z^2 + 26z - 9, we need to find two numbers that multiply to give us 3 times -9 = -27, and add up to 26.

One way to do this is to list all the factor pairs of -27 and look for the pair that has a sum of 26:

-27 and 1

-9 and 3

-3 and 9

-1 and 27

We can see that the pair that adds up to 26 is -3 and 9. So we can use these numbers to write the quadratic expression as a product of two binomials:

3z^2 + 26z - 9 = (3z - 1)(z + 9)

Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).

How do you find the percentage of yield in caculator?

Answers

To find the percentage of yield in a calculator, you can follow these steps:

1. Determine the actual yield and the theoretical yield of the reaction. The actual yield is the amount of product that was actually produced in the reaction, while the theoretical yield is the amount of product that should have been produced based on the balanced chemical equation.

2. Divide the actual yield by the theoretical yield to find the decimal form of the percentage yield.

3. Multiply the decimal form of the percentage yield by 100 to find the percentage yield.

For example, if the actual yield of a reaction is 15 grams and the theoretical yield is 20 grams, the percentage yield would be:

(15/20) x 100 = 75%

Therefore, the percentage yield of the reaction is 75%.

how is the bell shaped histogram?

Answers

A bell-shaped histogram is a type of graph that displays a normal distribution, which is a probability distribution that is symmetrical and has a characteristic bell shape.

The bell-shaped histogram is created by plotting the data on a horizontal axis and the frequency or probability on a vertical axis. The data points are grouped into intervals called bins, and the number of data points that fall into each bin is plotted as a bar. The bars are typically drawn adjacent to one another and connected with lines to create a continuous curve that represents the normal distribution.

The resulting histogram will have a characteristic bell shape, with a high point at the mean, and decreasing frequency or probability as the values move away from the mean in either direction. The width of the curve is determined by the standard deviation of the data, with wider curves indicating greater variation in the data.

The bell-shaped histogram is commonly used in statistical analysis to represent normally distributed data, such as the heights or weights of a population, test scores, or other measurements that tend to cluster around a central value with a predictable range of variation.

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.

Answers

Answer:

Step-by-step explanation:

y=9700(0.909)^x

# If the base of an exponential function is an element of the set (0,1) the function is decreasing as the value of 'x' is increasing from negative infinity to positive infinity.

the function y=9700(0.909)^x is an exponential function with a coefficient 9700 and base 0.909, as we increase the value of x from negative infinity to positive infinity, the value of y decreases. So the change between two consecutive 'y' values as 'x' increases indicate decay rather than growth.

And it can be written as y=9700(1-0.091)^x, therefore the percentage decrease is 9.1%

Answers

The most likely production for a rainfall of 40 mm is 56.4 quintals.

How to determine the production that correspond to the rainfall

From the question, we have the following parameters that can be used in our computation:

          Rainfall (mm) Production (quintals)

Mean           35                  50

S.D                5                    8

Coefficient of correlation = 0.8​

First, we need to calculate the regression equation, which is:

y = a + bx

Where

y is the predicted value of production x is the rainfalla is the interceptb is the slope of the regression line.

To calculate the intercept and slope, we use the following formulas:

b = r * (SDy / SDx)

a = Ymean - b * Xmean

Plugging in the given values, we get:

b = 0.8 * (8 / 5) = 1.28

a = 50 - 1.28 * 35 = 5.2

Therefore, the regression equation is:

Y = 5.2 + 1.28x

To find the most likely production for a rainfall of 40 mm, we plug in x = 40 into the regression equation:

Y = 5.2 + 1.28 * 40

Y = 56.4

Hence, the most likely production is 56.4 quintals.

Verifying trig identities can be difficult because they involve manipulating complex equations with multiple trigonometric functions that have various associated angles and coefficients.

For example, the Pythagorean Identity states that sin2θ + cos2θ = 1, which must be verified by using the identity sin2θ = 2sinθcosθ and substituting it into the equation. This results in a complex equation: 2sinθcosθ + cos2θ = 1, which must then be simplified and rearranged in order to show that it is true for all values of θ.

The area of a circle is 49π m². What is the circumference, in meters? Express your answer in terms of

π.

Answers

Answer: 14π

Step-by-step explanation:

The area of a circle can be expressed as πr^2. In this case, the area is given as 49π m², so we can write:

πr^2 = 49π

Dividing both sides by π, we get:

r^2 = 49

Taking the square root of both sides, we get:

r = 7

The circumference of a circle is given by 2πr, so the circumference in this case would be:

C = 2π * 7 = 14π

So the circumference of the circle with an area of 49π m² is 14π meters.

Write an equation that represents the relationship between the distance the car
has traveled in miles, d, and the amount of gas left in the tank in gallons, x.

Answers

Answer: The relationship between the distance a car has traveled in miles, d, and the amount of gas left in the tank in gallons, x, can be represented by the equation:

d = r * m

where r is the fuel efficiency of the car in miles per gallon and m is the amount of gas consumed in gallons.

Since x is the amount of gas left in the tank, we can write:

x = m_0 - m

where m_0 is the initial amount of gas in the tank.

Combining the two equations, we get:

d = r * (m_0 - x)

This equation represents the relationship between the distance the car has traveled in miles, d, and the amount of gas left in the tank in gallons, x.

Junior is looking into buying a new car he has $2000 for a down payment and he wants to pay $250 per month. for Ford mustang has the following equation for a special deal Y equals 275X +2500 and a dodge charger has a special deal of Y equals 250 X +1500. which deal would work better for him? explain your answer.

Answers

Answer:

Step-by-step explanation:

First, we need to calculate the cost of each car after 60 months.

For the Ford Mustang:

Y = 275X + 2500

Y = 275 * 60 + 2500

Y = 16500

For the Dodge Charger:

Y = 250X + 1500

Y = 250 * 60 + 1500

Y = 15000

Next, we can compare the total cost of each car to determine which is the better deal.

In this case, the Dodge Charger is the better deal as it costs $1500 less than the Ford Mustang over the course of 60 months.

It's important to keep in mind that these calculations are based on the assumption that Junior will only make the minimum payments of $250 per month. If he decides to make larger payments or pay off the car early, the total cost of each car will be different.

Additionally, there may be other factors, such as the reliability and maintenance costs of each car, insurance costs, fuel efficiency, and driving experience, that should also be considered before making a decision. Junior should research and weigh all these factors before making a final decision.

In conclusion, the calculation of the cost of each car after 60 months is just one aspect of the decision-making process when buying a car. Junior should consider all relevant factors and weigh the pros and cons of each option before making a final decision.

How to calculate Unit price of an item?

To calculate the unit price of an item, you have to understand that unit price means price per unit. To find the unit price we divide the total cost by the amount of items we are given in the question.

Given :

15x - 4y = 0

Where ,y is total cost in dollars of the trail mix and x is  the number of pounds bought.

To calculate , unit cost of trial mix , we need to calculate y

Therefore , from equation 15x - 4y = 0

We can say that,

y =(15/4)x

For unit cost we need to substitute x = 1

Thus, y = (15/4)*1

or

y = (15/4)

or

y = 3.75

Hence, the unit cost per pound of trail mix, in dollars is $3.75.
