In the football game, a penalty of -15 yards was applied to a gain of 43 yards. What was the net gain?

A = 58 yards

B = 32 yards

C = 28 yards

D = 18 yards

The solution to the conversions are: (1) 1.60934 km/min, (2) 20.8333 m/s, (3) 49.7097 mi/h, (4) 27.7778 m/s, (5) 118100.64 ft/h

1. 60mi/h to km/min  

First, convert miles to kilometers:

1 mile (mi) = 1.60934 kilometers (km)

60mi/h = 60 x 1.60934 = 96.5604km/h

Next, convert hours to minutes:

1 hour = 60 minutes

96.5604 km/h = 96.5604 km/h x (1 h / 60 min)

                        = 1.60934 km/min.

Therefore, 60 mi/h is equal to approximately 1.60934 km/min.

2. 75km/h to m/s

First, convert kilometers to meters:

1 kilometer = 1000 meters

75 km/h  = 75 km/h x (1000 m / 1 km)

               = 75000 m/h

Next, convert hours to seconds:

1 hour = 3600 seconds

75000 m/h = 75000m/h x (1 h / 3600 s)

                   = 20.8333 m/s.

Therefore, 75 km/h is equal to approximately 20.8333 m/s.

3. 80km/h to mi/h

First, convert kilometers to miles:

1 mile = 1.60934 kilometers

1 kilometers = (1/1.60934) mile

80 km/h = 80km/h x (1 mi / 1.60934 km)

              = 49.7097 mi/h.

Therefore, 80 km/h is equal to approximately 49.7097 mi/h.

4. 100km/h to m/s

First, convert kilometers to meters:

1 kilometer = 1000 meters

100 km/h = 100km/h x (1000 m / 1 km)

                = 100000 m/h.

Next, convert hours to seconds:

100000 m/h = 100000 x (1 h / 3600 s)

                    = 27.7778 m/s.

Therefore, 100 km/h is equal to approximately 27.7778 m/s.

5.  10m/s  to ft/h

First, convert meters to feet:

10 m/s = 10 x (3.28084 ft / 1 m)

           = 32.8084 ft/s.

Next, convert seconds to hours:

32.8084 ft/s = 32.8084 x (3600 s / 1 h)

                    = 118100.64 ft/h.

Therefore, 10 m/s is equal to approximately 118100.64 ft/h.

Answer: x = 11

Step-by-step explanation:

     We know that vertical angles are congruent to each other. We will create an equation to help us solve. Then, will isolate the x-variable with inverse operations.

128° = 8x + 40°

8x + 40° = 128°

8x = 88°

x = 11

Answer:

AB ≈ 8.1

Step-by-step explanation:

using the cosine ratio in the right triangle

cos40° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{6.2}{AB}[/tex] ( multiply both sides by AB )

AB × cos40° = 6.2 ( divide both sides by cos40° )

AB = [tex]\frac{6.2}{cos49}[/tex] ≈ 8.1 ( to the nearest tenth )

Answer:the values is y x 2=  the domain is no it does not make sense because it as nothing to do with the shape of the rainbow  

Step-by-step explanation:

a. The concentration would be 0.5 mg/L at approximately t = 40 hours.

b. The table representing the concentration of the drug in the bloodstream, t hours after administration is shown below.

c. A reasonable domain for this function is t ≥ 0.

d. The patient should receive the next intravenous dose of the drug in order to maintain a concentration above 1 mg/L and below 8 mg/L at t = 1.25 hour.

e. The concentration of the oral drug and the concentration of the intravenous drug would keep increasing over the first 20 hours after it is administered.

In order to determine the time when the concentration would be 0.5 mg/L, we would substitute the value of the concentration and then solve the quadratic function for time (t);

c(t) = 20t/(t² + 4)

0.5 = 20t/(t² + 4)

0.5(t² + 4) = 20t

0.5t² + 2 = 20t

0.5t² + 2 - 20t = 0

t² + 4 - 40t = 0

t² - 40t + 4 = 0

Time, t = 38.8998 ≈ 40 hours.

Part b

In this context, we would complete the table of values at various time (t) as follows;

t        0    2      4     6       8           10        12        14     16        18      20

c(t)    0    5      4      3     2.35      1.92     1.62     1.4    1.23     1.10    1.00

Part c

Since the concentration of the drug at time, t = 0 is equal to 0 mg/L and the concentration actually never becomes zero (0) for any value of time (t), we can reasonably infer and logically deduce that a reasonable domain for this quadratic function is t ≥ 0 or {0, ∞}.

Part d and e

Furthermore, the intravenous drug must be administered to the patient between the time interval 1.25 ≤ t ≤ 20 in order to maintain a concentration above 1 mg/L and below 8 mg/L.

The interest rate can drastically change the total amount paid to the lender, in the case of mortgages, up to thousands of dollars.The correct answer is c.

The interest rate of a loan is one of the most important factors to consider when shopping around for loans because it directly affects the cost of borrowing money. The interest rate determines the percentage of the loan amount that the borrower will have to pay back to the lender as interest over the loan's term.

A higher interest rate means that borrowers will have to pay more in interest over the life of the loan, increasing the total cost of borrowing. Conversely, a lower interest rate will result in lower interest payments and a reduced overall cost of the loan.

For example, in the case of a mortgage, which is a long-term loan, even a small difference in the interest rate can have a significant impact on the total amount paid to the lender. Over the course of a 30-year mortgage, a higher interest rate could result in thousands of dollars in additional interest payments.

Therefore, it is important to compare and consider different loan offers to find the best interest rate available. This can help borrowers save money and make more informed decisions about their borrowing options. The correct answer is c.

The scale of the dilation is 7/15.

The scale of dilation between two similar figures is the ratio of their corresponding side lengths. In this case, since triangle A'B'C is a dilation of triangle ABC, we can find the scale of dilation by comparing the corresponding side lengths.

Let's say that the scale of dilation is k. Then we can write:

AB' = k × AB

AC' = k × AC

BC' = k × BC

To find k, we can choose any two corresponding sides and set their ratio equal to k. For example, we can choose AB' and AB, and write:

AB' / AB = k

The weighted average of the points A, B, and C with weights 1, 4, and 1 respectively is (A + 4B + C) / 6.

To find the weighted average of the points A, B, and C with weights 1, 4, and 1 respectively, we first need to multiply each point by its corresponding weight and then add them together.

Finally, we divide the sum by the total weight.

The weighted sum of the points is:

(1 × A) + (4 × B) + (1 × C) = A + 4B + C

The total weight is:

1 + 4 + 1 = 6

Therefore, the weighted average of the points A, B, and C with weights 1, 4, and 1 respectively is:

(A + 4B + C) / 6

Note that the weight of B is four times that of A and C.

Therefore, the weighted average will be closer to B than A or C, reflecting the fact that B has a larger weight.

For example, if A = 3, B = 5, and C = 4, then the weighted average is:

(A + 4B + C) / 6 = (3 + 4 × 5 + 4) / 6 = 26 / 6 = 4.33.

d. The patient should receive the drug after about 19.78 hours

e. The shape of the concentration graph are similar, but the concentration of the oral drug is higher than the concentration of the drug administered intravenously

A function is a rule that maps input variables to output values.

a. The function modelling the concentration of the drug in the bloodstream after t hours indicates;

c(t) = 20·t/(t² + 4)
When the concentration is 0.5 mg/L, we get;

c(t) = 20·t/(t² + 4) = 0.5

(t² + 4) × 0.5 = 20·t

t² + 4 = 20·t ÷ 0.5 = 40·t

t² - 40·t + 4 = 0

t = (40 ± √((-40)² - 4 × 1 × 4))/(2 × 1) = (40 ± 12·√(11))/(2) = 20 ± 6·√(11)

The concentration will be 0.5 mg/L when t = 20 + 6·√(11) and t = 20 - 6·√(11)

d. The values in the table indicates that to maintain a concentration above 1 mg/L and below 8 mg/L, the patient must receive the next intravenous dose between the values obtained as follows;

The maximum value of the function is 5 mg/L when t = 2 hours, therefore, when c(t) = 1 mg/L, we get;

c(t) = 20·t/(t² + 4) = 1, which indicates that t = 10 ± 4·√6, which indicates that the time at which the concentration reduces to 1 mg/L again in the bloodstream is 10 + 4·√6 ≈ 19.78 hours

The patient should receive the next dose, after about 19.78 hours

e. The concentration of the oral drug, obtained from a similar question on the website, indicates that the maximum concentration is 64 mg/L, which is higher than the maximum concentration of the drug administered intravenously, which has a maximum concentration of 5 mg/L

Answer:

m = 25 + 6n

Step-by-step explanation:

To write a function for the amount of money Makayla spent going to the movies during the club, you need to consider two things: the annual registration fee and the discounted ticket price. The annual registration fee is a fixed amount that does not depend on the number of movie tickets Makayla purchases. The discounted ticket price is a variable amount that depends on the number of movie tickets Makayla purchases. You can use a letter, such as n, to represent the number of movie tickets Makayla purchases. Then, you can write an expression for the amount of money Makayla spent on movie tickets, which is 6 times n, or 6n. To find the total amount of money Makayla spent going to the movies during the club, you need to add the annual registration fee and the amount of money spent on movie tickets. This gives you the expression 25 + 6n. You can use another letter, such as m, to represent the total amount of money Makayla spent going to the movies during the club. Then, you can write an equation that relates m and n, which is m = 25 + 6n. This equation is a function that models the amount of money Makayla spent going to the movies during the club as a function of the number of movie tickets she purchased.

Lets explain how to factorize the difference of two cubes

- The factorization of the difference of two cubes like a³ - b³, is a

 product of a binomial and trinomial

- The binomial is the cube root of the first term and the second term

∵ The ∛a³ = a and ∛b³ = b

∴ The binomial is (a - b)

- We will find the trinomial from the binomial by square the 1st term

of the binomial and multiply the 1st term and the 2nd term of the

binomial with opposite sign of the binomial and square the 2nd

term of the binomial

∴ The trinomial is (a² + ab + b²

∴ The factorization of (a³ - b³) is (a - b)(a² + ab + b²)

* Lets solve the problem

∵ 8f³ - 216g³ is the difference of two cubes

∵ ∛(8f³) = 2f

∵ ∛(216g³) = 6g

∴ The binomial is (2f - 6g)

- Lets make the trinomial

∵ (2f)² = 4f²

∵ (2f)(6g) = 12fg

∵ (6g)² = 36g²

∴ The trinomial = (4f² + 12fg + 36g²)

∴ The factorization of 8f³ - 216g³ = (2f - 6g)(4f² + 12fg + 36g²)

∴ The value of the missing coefficient is 12.
