By performing a change of units, we will see that the distance from Los Angeles to Honolulu is 2,238 mi, so the correct option is D.

We know that the distance from Los Angeles to Honolulu is 1,946 nautical miles long.

And we know the relation:

1 nautical mile ≈ 1.15 miles

So we just ant to perform a change of units, to do so we can write:

1,946 nautical miles long = 1,946*(1.15 miles) = 2,238 mi

The statement correctly describes the relationship between the graph of f(x) and g(x)=f(x−7) is the graph of f(x) translated 7 units right.

The graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them.

According to the question we have

g(x)=f(x−7).

Given that f(x) then f(x + a) represents a horizontal translation of f(x).

If a > 0 then shift units left

If a < 0 then shift units right

Therefore, f(x - 7) represents a shift right of 7 units.

At (9, 0), the graph of the equation y = - 2/3 x + 6 intersect the x - axis.

How to create linear equation using two variables?
If an equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables. Such an equation has a pair of numbers as its solution, one for x and one for y, which further equalizes the two sides of the equation. A specific point on the graph represents the solution of a linear equation in two variables, ax + by = c, where the total of these two values will equal c when the x-coordinate is multiplied by a and the y-coordinate by b. Basically, there are infinitely many solutions to a linear equation with two variables.
The linear equations can be solved using substitution method.

Given, the equation of the graph is : y = (-2/3) x + 6 -(i)
Also, the equation of x-axis is: y = 0 -(ii)
Substituting (ii) in (i), we get,
0 = (-2/3)x + 6 ⇒ (-2/3)x = -6 ⇒ (2/3)x = 6 ⇒ x = 9
Thus, the point where the graph of the equation y = - 2/3 x + 6 intersect the x - axis is (9, 0).

Answer: 90 degree

Step-by-step explanation: the diameter of a circle compounds to an inscribed angle of  90 degree

Answer:

R ≈ 3.97 %

Step-by-step explanation:

Using the uniform distribution:

a) The height of the density function which is f(x) is [tex]\frac{1}{12}[/tex]

We know that for a uniform distribution we have two bounds, namely a and b. The probability or likelihood of finding a value of at lower than x is given by the following formula:

P (X < [tex]x[/tex]) = [tex]\frac{x-a}{b-a}[/tex]

Now where we have been mentioned that the two bounds are as follows:

a = - 5 (lower bound)

b = 7 (upper bound)

a) To find the height (h) of the density function we use the below given formula:

h = [tex]\frac{1}{b-a}[/tex]

Putting here the values of a and b we get the height as,

∴ h = [tex]\frac{1}{7-(-5)}[/tex]

⇒ h = [tex]\frac{1}{7+5}[/tex]

⇒ h = [tex]\frac{1}{12}[/tex]

Hence, the height of the density function f(x) is [tex]\frac{1}{12}[/tex]

As shown in the reference graph attached hereby with the question statement, if the linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time "x" measured in seconds, then,

(A) During (2 ≤ x ≤ 5) seconds in the time domain, the water balloon's height remains the same.

(B) During (0 ≤ x ≤ 2) seconds, the height of the water balloon is increasing.

(C) During (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the fastest.

(D) From Part (C), it can be justified that 5 ≤ x ≤ 9.5 is the interval where the balloon's height is decreasing, and, (5 ≤ x ≤ 6) is the interval where the slope is the steepest.

As per the question statement and the reference graph attached alongside, the linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time "x" measured in seconds.

We  are required to determine the correct time domains for four different situations, by observing the plotted graph.

Part (A) is to determine the correct time domain where the water balloon's height remains the same.

From the graph, it is clear that, the height remains constant at (y = 70), parallel to the x-axis from the 2nd second to the 5th second. Hence, During (2 ≤ x ≤ 5) seconds in the time domain, the water balloon's height remains the same.

Part (B) is to determine the correct time domain where the height of the water balloon is increasing.

From the graph, it is clear that, the slope of the concerned graph rises only from [(y = 40) to (y = 70)], starring from the 0th second until the 2nd second. Hence, During (0 ≤ x ≤ 2) seconds in the time domain, , the height of the water balloon is increasing.

Part (C) is to determine the correct time domain where the height of the water balloon decreases the fastest.

From the graph, it is clear that, the graph decreases thrice, first from [(y = 70) to (y = 40)], starting at the 5th second uptil the 6th second, then from [(y = 40) to (y = 10)], starting at the 6th second uptil the 9th second and lastly, from [(y = 10) to (y = 0)], starting at the 9th second till the 9.5th second. Here, we can easily calculate that, the balloon dropped 30ft in 1 sec at the first instance, 30ft in 3 seconds at the second instance and, 10ft in 0.5 seconds.

Since, [(30/1) > (10/0.5) > (30/3)],

Or, [30 > 20 > 10],

Thus, During (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the fastest.

Part (D) is to determine the correct statement mentioned under it's options, with judgement based on Part (C).

Option (i) states that [(5 ≤ x ≤ 9.5) is the interval where the balloon's height is decreasing] which is true, as we can observe from the graph that the slope is decreasing during the time interval of 5 to 9.5th seconds, although at different rates at different intervals.

Option (ii) states that [(8 ≤ x ≤ 9.5) is the interval where the slope is the steepest] which means that, during this above said interval, the height of the balloon drops the fastest which is false, as we have already proved in part (C) that during (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the fastest.

Option (iii) states that, [(6 ≤ x ≤ 8) is the interval where the balloon's height decreases the most] which is false, as balloons height falls the farthest by 30fts in two separate intervals, between (5 ≤ x ≤ 6) seconds and (6 ≤ x ≤ 9) seconds.

Finally, Option (iv) states that [(5 ≤ x ≤ 6) is the interval where the slope is the steepest] which means that, during this above said interval, the height of the balloon drops the fastest which is true, as we have already proved in part (C) that during (5 ≤ x ≤ 6) seconds, the height of the water balloon decreases the maximum in the shortest time period.

The ratio of the blue fish in the small tank to red fish in the large tank is 10 to 69.

Ratio is the relationship between two quantities.

Let x : y = ratio of the blue fish in the small tank to red fish in the large tank

Hence, there are x blue fish in the small tank for every y red fish in the large tank.

If in each tank, the ratio of red fish to blue fish is 3 to 4, then in each tank, in terms of x and y, the ratio is:

small tank :

red : blue = 3 : 4 = (3/4)x : x

large tank :

red : blue = 3 : 4 = y : (4/3)y

If the ratio of fish in the large tank to fish in the small tank is 46 to 5, then

(y + (4/3)y) : ((3/4)x + x) = 46 : 5

Simplifying the proportion,

(y + (4/3)y) : ((3/4)x + x) = 46 : 5

(7/3)y : (7/4)x = 46 : 5
