The interval should be 12 hours and 25 minutes for the two high tides and two low tides.

What is interval ?

An interval refers to the amount of time it takes for a tide to go from high to low or low to high

The reason for two high tides and two low tides each day is due to the gravitational pull of the moon and the sun on Earth's oceans. These gravitational forces cause the water in the oceans to bulge, creating high tides. The gravitational pull of the moon is stronger than that of the sun, so the moon has a greater impact on tides.

The time it takes for the tide to go from high to low and back to high is called the tidal period, which is about 12 hours and 25 minutes. This is not exactly 24 hours because the Earth is also rotating on its axis, so the position of the Moon and the Sun relative to a specific location on the Earth's surface is constantly changing.

So, the interval should be 12 hours and 25 minutes for the two high tides and two low tides.

The distance Jon travels to work is 472.5 miles.

Let d be the distance Jon travels to work.

The time it takes to drive is 20 minutes and the time it takes to bike is 45 minutes.

The difference in speed between driving and biking is 14.5 mph.

We can set up the following equation:

20min * (14.5mph + x) = 45min * x

Solving for x gives us the average speed of Jon on the bike, which is 10.5 mph.

Now we can use the distance formula to solve for d:

d = rate * time

d = 10.5mph * 45min

d = 472.5 miles

Therefore, the distance Jon travels to work is 472.5 miles.

The total distance travelled on the cycle is 30.46m and the acceleration  is the last 8 seconds is 0.85 m/s².

"Acceleration is the measure of the speed at which velocity changes."

OR "Acceleration depends upon the velocity if the velocity continously increases or decreases the acceleration will be produced."

Positive acceleration results from continuously increasing velocity.

Negative acceleration will be negative if the velocity is continuously decreasing.

FORMULA

Acceleration is defined as a change in velocity divided by time, or a = (Vf-Vi)/t UNIT.

Meter/second+square, or m/S², is the SI unit of velocity in the MKS system.

a. Total distance = Hypotenuse₁ + mid distance + Hypotenuse₂

Hypotenuse₁ = [tex]$ \sqrt{10^2 + 6^2} $[/tex]

Hypotenuse₁ = 11.66m

mid distance = 12 - 6

Step-by-step explanation:

The mystery number is 9. The least common multiple of 3 and 36 is 36. When you pair 9 with 36, their least common multiple is still 36. 9 is greater than 6, but less than 12. Therefore, the mystery number is 9.

The sine function that intersects its midline at (0,-6) and then has a minimum point at (2.5,-9) is given as follows:

y = 3sin(0.6πx) - 6.

The standard definition of the sine function is given as follows:

y = Asin(Bx) + C.

For which the parameters are given as follows:

The midline is at y = -6, while the minimum point is at y = -9, hence the amplitude of the function is given as follows:

A = -6 - (-9)

A = 3.

A sinusoidal function with amplitude 3 should oscillate between -3 and 3, while it oscillates between -3 and -9, hence the vertical shift is given as follows:

C = -6.

The distance from the midline to the minimum value is of 3/4 of the period, hence the period is of:

3/4P = 2.5

P = 4 x 2.5/3

P = 10/3.

This means that the parameter b is obtained as follows:

2π/B = 10/3

10B = 6π

B = 0.6π

This means that the function is defined as follows:

y = 3sin(0.6πx) - 6.

We can say that in geometry, Babylonian mathematicians were able to calculate the area of a trapezoid, suggesting that they were aware of the Pythagorean Theorem.

The Pythagorean Theorem, sometimes known as the Pythagorean Theorem, is the basic Euclidean geometry relationship between a right triangle's three sides. According to this rule, the area of a square with the hypotenuse side equals the sum of the areas of squares with the other two sides. The Pythagorean Theorem, often known as the generic algebraic notation a2 + b2 = c2, states that the square that crosses the hypotenuse of a right triangle opposite the right angle equals the sum of the squares that span the sides of a right triangle.

Step-by-step explanation:

f(1) = 5 = 4*1 +1

f(9) = 37 = 4*9+1

f(6) = 4*6+1 = 25

f(f(6)) = f(25) = 4*25+1 =101

Answer:

  101

Step-by-step explanation:

Given the values of a linear function f(1) = 5 and f(9) = 37, you want the value of f(f(6)).

The given ordered pairs are (1, 5) and (9, 37). Using these, we can find the slope of the function to be ...

  m = (y2 -y1)/(x2 -x1)

  m = (37 -5)/(9 -1) = 32/8 = 4

The y-intercept is ...

  b = y -mx

  b = 5 -4(1) = 1

So the function in slope-intercept form is ...

  y = mx +b

  f(x) = 4x +1

The value of f(6) is ...

  f(6) = 4·6 +1 = 25

The value of f(f(6)) is ...

  f(f(6)) = f(25) = 4·25 +1 = 101

The value of f(f(6)) is 101.

The area of the region enclosed by the inner loop of the curve can be calculated by integrating the function r = 6 + 12 sin θ over the interval of θ.

The area of the inner loop is given by Area = 1/2 ∫r^2 dθ = 1/2 ∫(6 + 12 sin θ)^2 dθ

We can solve this integral by breaking it into two parts: Area = 1/2 (∫(6 + 12 sin θ)^2 dθ) = 1/2(∫36 + 72sin θ + 144sin^2 θ dθ)

The first integral is simple and equals to 36*θ and the second one is equal to 48θ - 48cos(2θ)

The limits of integration are [0, 2π]

So the area of the inner loop is 1/2(36*2π + 48(2π) - 48(2)) = 72π

So the area of the region enclosed by the inner loop of the curve is 72π square units.

Given the following P(A) = 0.3, P(B) = 0.2, P(A) and P(B) 0.06. So, A and B are independent. This can be solved using probability concept.

The word "probability" derives from the Latin word "probitatem," which means "credibility, likelihood," from the noun probabilis in the 14th century (see probable). The phrase was first used in a mathematical meaning in 1718.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

Given that,

P(A) = 0.3

P(B) = 0.2

P(A and B) = 0.06

Now, P(A and B) = P(A) × P(B)

or, 0.06 = 0.3 × 0.2

So, A and B are independent.

The equation of the line that passes through the points (-6,4) and (-2,2) is y - 4 = -1/2(x + 6)

What is the equation of the line?

To find the equation of a line that passes through two given points, we can use the point-slope form of the equation of a line, which is:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line, and m is the slope of the line.

The slope of the line can be found by using the two points:

m = (y2 - y1) / (x2 - x1)

So,

m = (2 - 4) / (-2 - (-6)) = -2/4 = -1/2

We know that the line passes through the point (-6,4) so we can substitute the values into the equation:

y - 4 = -1/2(x + 6)

Hence, the equation of the line that passes through the points (-6,4) and (-2,2) is y - 4 = -1/2(x + 6)

The area of the part of the plane 5x + 3y + z = 15 that lies in the first octant is 15x^3/6 + 45x^2y/2.

Area is a measure of the size of a surface or the amount of space it takes up. It can be measured in square units such as square feet, square meters, or acres. Area is used to describe the size of a two-dimensional object or shape, and is often used when discussing the size of a plot of land, a room, or other geographical area.

The first octant is defined as the area in the three-dimensional Cartesian coordinate system where all the coordinates are positive. In this case, the equation 5x + 3y + z = 15 can be rearranged to solve for z: z = 15 - 5x - 3y. This new equation can then be used to find the area of the plane that lies in the first octant by integrating the equation over the area of the octant.

To solve for the area, we must first find the boundaries of the octant. Since all coordinates must be positive, the boundaries of the octant are x = 0, y = 0, and z = 0. The area of the plane that lies in the first octant is then computed using the triple integral:

Area = ∫∫∫ 0 0 0 15-5x-3y dzdydx

= ∫∫ 0 0 (15x + 45y)dydx

= ∫ 0 (15x^2/2 + 45xy)dx

= 15x^3/6 + 45x^2y/2
