Step-by-step explanation:

exponential function

Two variables y and x have an exponential relationship if

where C and k are real numbers. Many natural phenomena are modeled using exponential functions, including in finance where investment growth can be calculated using the exponential function.

The situation described in the question is modeled as follows:

where A is the total value of the investment, p is the initial value of the investment, and n is the number of years the money has been invested. We know that p = 2500 and n = 18, so we calculate A

The difference between the roots of the quadratic equation x^2−14x+q=0 is 6. Find q.

### Answer

the value of q is 40

Step-by-step explanation:

In the quadratic equation ax² - bx + c = 0, where

- at = 1
- b is the sum of its two roots
- c is the product of its two roots

Suppose the roots of the quadratic equations are x and y

∵ The quadratic equation is x² - 14x + q = 0

∴ a = 1 , b = 14 y c = q

∵ b is the sum of its two roots

∵ Its roots are x and y

∴ x + y = 14 ⇒ (1)

∵ The difference between the roots is 6

∴ x - y = 6 ⇒ (2)

Now we have a system of equations to solve it.

Add equations (1) and (2).

∴ 2x = 20

- Divide both sides by 2

∴ x = 10

Substitute the value of x into equation (1) or (2) to find y

∵ 10 + y = 14

- 10 left on both sides

∴ y = 4

∵ c is the product of the two roots

∴ c = 10 × 4 = 40

∵c = q

∴ q = 40

the value of q is 40

What is the formula y = 2x( z + 3 find y if z = 2 and x = 4)

### Answer

Answer:

j = 40

Step-by-step explanation:

In the formula y = 2x( z + 3), replace x with 4 and replace z with 2:

y = 2(4)(2 + 3), or (by first doing the addition in parentheses),

y = 2(4)(5) = 40

If x= 4 and z= 2, you would write the equation as y= 2*4 (2 + 3).

2 4= 8 and 2+3= 5, so I think you add them together and y=13

Cameron wants to measure a poster frame, but only has an 81/2 x 11 inch sheet of paper.

### Answer

Cameron wants to measure a poster frame, but only has an 8 1/2 x 11 inch sheet of paper.

He puts the long side of the paper along the long side of the frame several times and discovers that the frame is 4 sheets long. How big is that in inches?

Answer:

Step-by-step explanation:

datum.

The long edge of the paper is 11 inches.

And the short or wide edge of the paper is

Based on the question, you put the long side of the paper along the long side of the frame several times and find out that the frame is 4 sheets long.

The long brim is 11 inches.

The long side of the poster frame is four times the long side of the paper, so =

Hence the long edge of the poster frame

The air pressure of each tire in a group is normally distributed with a mean value of 39.2

pounds per square inch (psi) and a standard

2.5 psi deviation. If there is a band in this group

a z-score of -1.8, determine the air pressure.

### Answer

The air pressure in the tire is 34.7 psi.

Step-by-step explanation:

The z-score formula is z = (x - μ)/σ, where

- x is de score
- μ is the average
- σ is the standard deviation

∵ The air pressure of each tire in a group is normally distributed

39.2 pounds per square inch (psi) on average

∴ μ = 39.2

∵ A standard deviation of 2.5 psi.

∴ σ = 2.5

∵ This group has a z-score of -1.8

∴z = -1,8

- Replace these values in the Z-Score formula

∵

- Multiply both sides by 2.5

∴ -4,5 = x - 39,2

- Add 39.2 to both sides

∴ 34,7 = x

The air pressure in the tire is 34.7 psi.

Write the sentence as an expression. Then evaluate when y=20. the quotient of 40 and the difference of a number and and 16.

### Answer

Answer:

Step-by-step explanation:

Be the quotient represented by "Q".

Datum:

The difference between a number "y" and 16 is

The quotient is the answer we get by dividing two terms. Here the first term is 40 and the second term is . So we divide both terms to get an expression for "Q".

The quotient of 40 and is given as follows:

Now we need to find the quotient as . In the above expression, replace "y" with 20 and calculate the quotient "Q". Is everything,

Therefore, if the value of "y" is 20, the quotient is 10.

### Answer

Answer: 315,250

Step-by-step explanation:

1. Add the numbers together

245.000 + 46.000 + 132,00 + 838.000 = 1,261000

2. Divide by the number of mentions (4)

1.215.046 ÷ 4 = 315250

Answer:

315.250

Step-by-step explanation:

The average is the same as the mean

To find the answer to this question, you must first:

1. First add all the numbers together

245.000 + 46.000 + 132.000 + 838.000 = 1.261.000

2. Then divide by the number of your numbers

1.261.000 ÷ 4 = 315.250

Spin a spinner numbered 1 through 5 and flip a coin. What is the probability that an odd number appears and that the coin is coin?

a) 2/5

b)3/10

C)4/5

Subject: none of the above

### Answer

Answer:

The correct answer is B. 3/10.

Step-by-step explanation:

1. Let's Calculate the Probability of Rolling an Odd Number:

We can draw an odd number (1, 3 or 5) from 5 events. This means that the probability of choosing an odd number is:

3/5

2. Let's calculate the probability of "tails" on the coin:

We can flip a coin and get a coin in one of the following two events, meaning the probability of getting a coin on the coin is:

1/2

3. These are independent events because the fact that an odd number is rolled does not affect the probability that the coin is coin, such as:

Probability of an odd number and number on the coin =

3/5 * 1/2 = 3/10

The correct answer is B. 3/10

Als cos -105º = -0.26 in csc -105º = -1.03, give cos 105º = in csc 105º = .

### Answer

Answer:

Cosine (105°) = -2.6

csc (105°) = 1,03

Step-by-step explanation:

Since cos(-105°) = -0.26 {The negative sign is due to the angle -105° being in the third quadrant where cos is negative}

Again, since csc(-105°) = -1.03 {{The negative sign is due to the -105° angle in the third quadrant where csc is negative}

Now cos(105°) = -2.6 because 105° is in the second quadrant and the value of cos here is negative.

And csc(105°) = 1.03 because 105° is in the second quadrant and here the value of csc is positive. (Answer)

Answer:

cos105= 2.6

csc105= 1,03

José wants to bake a lot of cookies to take to a party. The chocolate chip cookie recipe you're using calls for 1.5 cups of flour. The recipe yields 2 dozen cookies. If you want to bake seven dozen cookies, how many cups of flour do you need?

### Answer

Answer:

5.25 Bags.

Step-by-step explanation:

We were told that the chocolate chip cookie recipe you are using calls for 1.5 cups of flour. The recipe yields 2 dozen cookies. We are asked to find the cups of flour needed to make 7 dozen cookies.

First, we divide 1.5 cups by 2 to find the amount of flour needed for one batch of cookies and multiply the result by 7 as follows:

Therefore, 7 dozen cookies require 5.25 cups of flour.

10.5 is the answer because you're making 1.5 7 times
