Answer:

5.22 is the answer required

Answer:

4 nautical miles per hour

Step-by-step explanation:

Speed = Distance / Time

Distance = Speed x time

D1 = D2

S1 = 16 nautical miles per hour

t1  =10 hours

We know S2 is unknown and the t2 = 8 hours

So, we take

S1 x T1 = S2 x T2

16 x 10 = S2 x 8

S2 = 16 x 10 / 8

S2 = 20 nautical miles per hour

20 - 16 = 4 nautical miles per hour

So, it has to increase its speed by 4 nautical miles per hour

Answer: 4 nautical miles per hour

It is given that in the first case, the ship takes 10 hours to travel at the speed of 16 nautical miles per hour. distance=speed × time=16×10=160 nautical miles. Therefore, the answer to the above question is 4 nautical miles per hour.

First make the graph of the functions, then  if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.

Symmetric

A figure or shape that can be divided into two equal parts by a line is called symmetric figures.

Inverse Functions

The inverse function of a function f  is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by F^-1.

The legs of a right isosceles triangle are the height and the base of the right isosceles triangle.

It is known that an isosceles triangle is a triangle which has two equal sides.

It is a right isosceles triangle when one side of the triangle is a perpendicular dropped from the vertex and forms a right angle with the base.

As the two sides are equal, the base also turns out to be perpendicular to the height forming a hypotenuse of the third side.

Hence, the two perpendiculars base and height are considered to be the legs of the right isosceles triangle.

The value of 0 1 is 1.

This is because any number to the power of 0 is equal to 1. This is part of the fundamental rules of exponents in mathematics. For example, if we take 2 to the power of 0, that would be equal to 2^0=1.

Similarly, 5^0=1, and so on. This is because any number to the power of 0 is equal to 1, regardless of the number. This is because any number multiplied by 1 is equal to itself. This holds true for 0 as well, and so 0^1=1. This is why the value of 0 1 is 1.

This is a basic mathematical equation in which the answer is 1. This equation can be used to illustrate the concept of addition, which is the process of combining two numbers to get a total.

Consider following image.

To determine if a graph has a positive or negative leading coefficient, look at the sign of the coefficient of the first term of the equation for the graph. If the coefficient is positive, the graph has a positive leading coefficient. If the coefficient is negative, the graph has a negative leading coefficient.

To determine the sign of the leading coefficient of a graph, first look at the equation for the graph. The leading coefficient of a graph is the coefficient of the first term in the equation, so find the coefficient of the first term. If the coefficient of the first term is positive, then the leading coefficient is positive. If the coefficient of the first term is negative, then the leading coefficient is negative. For example, if the equation is y = 4x2 + 3x + 5, the coefficient of the first term is 4, and so the leading coefficient is positive. Conversely, if the equation is y = -2x2 + 3x + 5, the coefficient of the first term is -2, and so the leading coefficient is negative.

Step-by-step explanation:

To graph the solution set to the given system of inequalities, we can begin by graphing the two inequalities separately. For the first inequality, y > x^2 – 2, we can graph the function y = x^2 – 2 on the coordinate plane and shade the region above the graph. This will represent the values of x and y that satisfy the inequality.

For the second inequality, y ≥ –x^2 + 5, we can graph the function y = –x^2 + 5 on the coordinate plane and shade the region below the graph. This will represent the values of x and y that satisfy the inequality.

Next, we can combine the two graphs by intersecting the shaded regions. The resulting graph will show the solution set to the system of inequalities. The solution set can be identified as the points on the coordinate plane that are contained within the shaded region on the combined graph.

Overall, to modify the graphs of f(x) and g(x) to graph the solution set to the given system of inequalities, we can graph the functions y = x^2 – 2 and y = –x^2 + 5 on the coordinate plane and shade the regions that satisfy the inequalities. The solution set can then be identified as the points within the shaded region on the resulting combined graph.

To solve for x in an angle, you first need to identify what type of angle you are dealing with. Depending on the type of angle, you will use different formulas to solve for x. For example, if you are dealing with a right angle, you can use the Pythagorean Theorem to solve for x.

The value of the sine of angle D to the nearest hundredth will be 0.25.

The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.

The sine law in the triangle ΔCDE is given as,

CD / sin E = DE / sin C = EC / sin D

In triangle ΔCED, the measure of angle ∠E = 90°, ED = 63, DC = 65, and CE = 16. Then we have

65 / sin 90° = 63 / sin C = 16 / sinD

Compare the first and the last term, then we have

65 / sin 90° = 16 / sin D

65 = 16 / sin D

sin D = 16 / 65

Answer:

slope of line w = - [tex]\frac{8}{4}[/tex]

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{5}{8}[/tex] x + [tex]\frac{9}{4}[/tex] ← is in slope- intercept form

with slope m = [tex]\frac{5}{8}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{8} }[/tex] = - [tex]\frac{8}{5}[/tex]

To graph a linear equation which is in the form of a straight line one easy method is by identifying two points on that line and drawing a straight line passing through the two points.

A linear equation of the form y = mx + c having slope m and y-intercept c is a straight line.

To find the two points, we can substitute a value for one variable and find the corresponding value of the other variable. In this case

For x = 0

y = -5×0 + 3

y = 3

So (0, 3) is a point on the line y = -5x + 3.

Similarly for y = 0

0 = -5x + 3

5x = 3

x = 3/5 = 0.6

So (0.6, 0) is a point on the line y = -5x + 3.

Now we can graph y = -5x + 3 by joining (0, 3) and (0.6, 0). Refer the attached figure for the graph.
