According to the statement 25t is the distance between the ships after t hrs.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental relationship in Euclidean geometry between the three sides of a right triangle. It states that perhaps the area of something like the square on which side would be the hypotenuse is equivalent to the sum of something like the areas of the squares on each of the other two sides.

The Pythagorean theorem is only valid for right-angled triangles. When any two numbers are known, we can use Pythagoras' theorem to compute the unknown sides of something like the triangle. Other real-world applications of Pythagoras' theorem include engineering and architecture.

The first ship travels north at 20 kilometers an hour, while the second travels west at 15 miles per hour.

equation for the given distance between boats after t hours:

C² = a² + b²

C = √(a² + b²)

a = dist. traveled in t hrs. of the 1st ship.

b = dist. traveled in t hrs. by 2nd ship.

c = dist. between the two ships after t hrs. (d)

Using formula Distance  = speed * time (t)

d = √((20t)²+(15t)²)

d = √(625t²)

d = 25t is the distance between the ships after t hrs.

Answer: about 47 haircuts

The given scale for the map is 1 in. : 15 mi., gives the actual distance corresponding to the map distance of 4.5 in. as 67.5 mi.

In the question, we are given that the scale of a map is 1 in.: 15 mi.

We are asked to find the actual distance corresponding to the map distance, given the map distance is 4.5 in.

The scale given to us is 1 in. : 15 mi.

This means that 1 inch on the map represents 15 mi. in the actual case.

Thus, the actual distance corresponding to the map distance of 4.5 in. is 15 * 4.5 mi. = 67.5 mi.

Thus, The given scale for the map is 1 in. : 15 mi., gives the actual distance corresponding to the map distance of 4.5 in. as 67.5 mi.

An equation of the tangent line to curve [y = e⁶ˣ cos x] at the given point  (0, 1) is y = x + 6.

At a given point, the tangent line of a curve is a line that really just contacts the curve (function). In calculus, the tangent line may connect the curve at any other point(s), and it may also cross the graph at any other point(s).

Now, as per the given question;

Because of this, point (0,1) is a tangent point;

y = f((0) = e⁰cos0 = 1.

We differentiate to get the slope of the tangent line m. Tangent line equation:

y' = 6e⁶ˣcosx - e⁶ˣ sinx;

Thus, the slope of the curve becomes;

m = f'(0) = 6.

Substituting the values of slope and coordinates (0, 1).

y = 6 + 1(x - 0),

Simplifying the equation.

y = x + 6

Thus, the equation of the tangent line to the given curve is y = x + 6.

Answer:

80 percent of the students are right handed while the 20 percent are left handed

Answer: A

400/500=n/100

or 80%

Step-by-step explanation:

One ratio should represent the numbers of students, and the other ratio should show the percent out of 100.

There are 400 right-handed students out of 500; this ratio is 400/500

The percent, n, is unknown, so this ratio is n/100

Answer:

Whole numbers

Step-by-step explanation:

Integers and whole numbers are similar, but integers contain negatives and whole numbers do not. Since a city cannot have a negative population count, we'd prefer whole numbers.

Rational numbers allow for non-whole numbers, but again, a city can't havea population of something and a half person. We again prefer whole numbers.

Answer:

Whole Numbers

Step-by-step explanation:

So cities Have complete number the represent it so integers are negative numbers and fractions and rational numbers are fractions so whole number is the only number that are complete and is not a fraction so therefore the only answer it could be is whole numbers

The process of making estimates and drawing conclusions about one or more characteristics of a population through analysis of sample data drawn from the population is known as statistical inference.

Inferential statistical analysis infers attributes of a population, for instance by testing hypotheses and generating estimates. Statistical inference is the process of employing data analysis to infer properties of an underlying probability distribution. The observed data set is thought to be a sample of a broader population. Comparable to descriptive statistics is inferential statistics. The focus of descriptive statistics is exclusively on the characteristics of the observed data; it is not predicated on the idea that the data are representative of a wider population. In machine learning, the phrase "create a prediction by evaluating an already trained model" is commonly used instead of "infer." Statistical inference uses data that has been sampled from a population to make claims about that population.

The total number of candies in the store is 312. It is obtained by using the concept of exponent and power on the given problem.

What is an Exponent?

The number of times a quantity is multiplied by itself is referred to as an exponent or power of the given quantity. For eg: 25, where 5 is an exponent or power of 2 and 2 is called the base of exponent 5. Any quantity raised to the power 0 always returns 1 as result.

Calculation of the total number of candies in the store

(36)2 * 30

Using the properties of an exponent, we have

A number with an exponent of 0 always gives 1

(36)2 * 1

(3)6×2 * 1

312 * 1

The equation of the perpendicular bisector of the segment with the endpoints located at D(-2  ,-4) and E(2 , 1) is y = -4/5x - 3/2.

A perpendicular bisector of a segment is a line that divides the segment into two equal parts forming right angles at the point of intersection.

To get the perpendicular bisector of a segment, get the point of intersection of the two lines which is the midpoint of the segment.

midpoint (x , y) = [(x1 + x2)/2 , (y1 + y2)/2]

midpoint (x , y) = [(-2 + 2)/2 , (-4 + 1)/2]

midpoint (x , y) = (0 , -3/2)

Get the slope of the perpendicular bisector of a segment by taking the negative reciprocal of the slope of the segment.

slope of segment = (y2 - y1)/(x2 - x1)

slope of segment = (1 - -4)/(2 - -2)

slope of segment = 5/4

slope of the perpendicular bisector = -4/5

Solving for the y-intercept, b, plug in the point (0 , -3/2) and the slope -4/5 to the slope-intercept form of the equation, y = mx + b.

y = mx + b

-3/2 = -4/5(0) + b

b = -3/2

Setting up the equation in slope-intercept form, where m = -4/5 and b = -3/2.

y = mx + b

y = -4/5x - 3/2
