Point Z is at a horizontal distance of 15 meters from the left- most point of the dam . What is the height of the dam at point Z?

Answers

Answer 1

Complete Question:

The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.

Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?

Answer:

The height is 36 meters

Step-by-step explanation:

Given

\(y = 24 * \frac{x}{10}\)

Required

The interpretation of the question is to determine the value of y when x = 15

Substitute 15 for x in: \(y = 24 * \frac{x}{10}\)

\(y = 24 * \frac{15}{10}\)

\(y = 24 * 1.5\)

\(y = 36\)

The height is 36 meters

The first term of the arithmetic sequence is 503.

What is arithmetic progression?

The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression

A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.

Given that the arithmetic sequence in which a61= 293 and the common difference is -3.5.

The first term will be calculated as,

a₆₁ = a₁ + d(n-1)

a₁ = a₆₁ + 3.5( 60 )

A circle has a diameter of 24 in what is the circumference pi is 3.14

Answers

Answer:

The circumference of a circle is calculated using the formula: C = πd, where C represents the circumference and d represents the diameter of the circle.

In this case, the diameter of the circle is given as 24 inches.

Using the formula, we can substitute the values:

C = πd

C = 3.14 * 24

C ≈ 75.36 inches

Therefore, the circumference of a circle with a diameter of 24 inches (and using π = 3.14) is approximately 75.36 inches.

At time t=0, a tank contains 20 oz of salt dissolved in 50 gallons of water. Then brine containing 6 oz of salt per gallon of brine is allowed to enter the tank at a rate of 2 gal/min and the mixed solution is drained from the tank at the same rate.
(a) How much salt is in the tank at an arbitrary time? ans in oz
(b) How much salt is in the tank at time 15 min? ans in oz

Answers

a) The amount of salt in the tank at any arbitrary time (t) is 2t + 20 ounces.

b) There are 50 ounces of salt in the tank at time 15 min.

The amount of salt in the tank at an arbitrary time can be calculated using the formula: M = (R * t) + M0, where M is the amount of salt in the tank, R is the rate of brine entering the tank, t is the time elapsed, and M0 is the initial amount of salt in the tank. In this case, M = (2 * t) + 20.

To calculate the amount of salt in the tank at a time of 15 minutes, we can substitute t = 15 into our equation. This gives us M = (2 * 15) + 20 = 50 ounces.

Mathematically, the amount of salt in the tank can be calculated by using the formula M = (R * t) + M0, where M is the amount of salt in the tank, R is the rate of brine entering the tank, t is the time elapsed, and M0 is the initial amount of salt in the tank.

This formula can be used to calculate the amount of salt in the tank at an arbitrary time by substituting the relevant values for R, t, and M0. The amount of salt in the tank at a specific time can also be calculated by substituting in the relevant time value (t) for the equation.

Answer:

The equation a=0.003x^2+21.3 models the average ages of women when they first married since the year 1940 in the United States. In this equation, a represents the average age and x represents the years since 1940. To estimate the year in which the average age of brides was the youngest, we need to find the minimum value of the quadratic function a=0.003x^2+21.3. This can be done by using the formula x=-b/2a, where b is the coefficient of x and a is the coefficient of x^2. In this case, b=0 and a=0.003, so x=-0/(2*0.003)=0. This means that the average age of brides was the lowest when x=0, which corresponds to the year 1940. The value of a when x=0 is a=0.003*0^2+21.3=21.3, so the average age of brides in 1940 was 21.3 years old. This is consistent with the historical data, which shows that the median age of women at their first wedding in 1940 was 21.5 years old. The average age of brides has been increasing since then, reaching 28.6 years old in 2021.

Question 1:

(b) So the cost of parking for a full 24 hours would be 24 times the cost per hour.

Question 2:

The given system of equations is inconsistent and has no solution.

(a) To represent Elaine's total parking cost, C, in dollars for t hours, we need to know the cost per hour. Let's assume the cost per hour is $x.

(b) If Elaine wants to park her car for a full 24 hours, we can substitute t = 24 into the equation from part (a):

C = x * 24

Question 2:

To solve the linear system:

-x - 6y = 5

x + y = 10

We can use the elimination method.

Multiply the second equation by -1 to create opposites of the x terms:

-x - 6y = 5

-x - y = -10

Add the two equations together to eliminate the x term:

(-x - 6y) + (-x - y) = 5 + (-10)

-2x - 7y = -5

Now we have a new equation:

-2x - 7y = -5

To check the answer, we can substitute the values of x and y back into the original equations:

From the second equation:

x + y = 10

Substituting y = 3 into the equation:

x + 3 = 10

x = 10 - 3

x = 7

Checking the first equation:

-x - 6y = 5

Substituting x = 7 and y = 3:

-(7) - 6(3) = 5

-7 - 18 = 5

-25 = 5

Answer:

There are six possible outcomes when rolling a die, each of which is equally likely. Of these six outcomes, three are greater than 2 (3, 4, 5) and three are not (1, 2, 6). Therefore, the odds in favor of rolling a number greater than 2 are 3 to 3, or simply 1 to 1. Alternatively, we could express this as a probability: the probability of rolling a number greater than 2 is 3/6, or 1/2, since there are three favorable outcomes out of a total of six possible outcomes.
