An ant travels at a constant rate of 30 cm every 2 minutes. at what pace does the ant travel per centimeter?

Answers

The ant travels at a pace of 1/15 mins per centimeters.

What is Pace?

Meaning of pace is rate of movement.

Pace is the inverse of speed.

If speed is measured in units of distance per unit of time then pace is measured in units of time per unit of distance.

We know speed is total distance travelled in the total time taken

speed = distance/time

According to the given question:

Ant travels 30cm in every 2 minutes

Distance travelled by ant = 30 cm

Time taken to travel this distance = 2 minutes

Therefore, speed of the ant is

30/2 = 15 cm per min

Now pace = inverse of speed

pace = 1/15 min per cm

Answers

The number of customers Alejandro will need in order to break even is 38 customers.

How to find the number of customers to break even?

Given data:

Cost of business = 48 x + 500

Income = R = 65 x - 145

Let x is the number of customers.

Income equation  

R= 65x- 145

Substitute 48x + 500  for y

48x + 500 = 65x -145

Answers

The distance between the two towns is 49 km

What is average speed?

Average speed is calculated by dividing distance by time (eg miles/hour).

The entire distance traveled by the object in a specific amount of time is its average speed. A scalar quantity, average speed, exists. The magnitude serves as its representation, and it lacks direction.

A body's average speed is its mean value over a given amount of time. Since a moving body's speed fluctuates over time and is not constant, an average speed formula is required. The total time and total distance numbers can be used, even with fluctuating speed, and with the aid of the average speed formula, we can get a single value to represent the entire motion.

Difference in times = 12:42 - 11:32 = 1.17 hours

Formula:

Distance = speed * time

               = 42 * 1.17

Suppose that R(x) is a polynomial of degree 13 whose coefficients are real numbers.
Also, suppose that R(x) has the following zeros.

2, -4, 3i, -4+i

Answer the following.
(a) Find another zero of R(x).

(b) What is the maximum number of real zeros that R(x) can have?

(c) What is the maximum number of nonreal zeros that R(x) can have?

Answers

Answer:

(a)  Other zeros:  3i  and  -4-i

(b)  9

(c)  10

Step-by-step explanation:

Given information:

Polynomial function with real coefficients.Degree:  13Zeros:  2, -4, 3i, -4+iPart (a)

For any complex number  [tex]z=a+bi[/tex], the complex conjugate of the number is defined as  [tex]z^*=a-bi[/tex] .  

If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.

Therefore, if R(x) is a polynomial with real coefficients, and 3i is a root of R(x)=0, then its complex conjugate -3i is also a root of R(x)=0.

Similarly, if -4+i is a root of R(x)=0, then its complex conjugate -4-i is also a root of R(x)=0.

Part (b)

The degree of the polynomial is the greatest of the exponents of its various terms.  

The degree of R(x) with just the given roots (including the complex conjugates) is 6, which includes 2 real zeros.

As the actual degree of R(x) is 13, the maximum number of real zeros would be 7 more than the given real zeros.

Therefore, the maximum number of real zeros that R(x) can have is 9.

Part (c)

For each complex root there is also a complex conjugate root.

We have been given 2 complex zeros and 2 real roots, so when we include the complex conjugates, the degree of R(x) is 6.

The actual degree of R(x) is 13, so the maximum number of non-real zeros is 6 more (as they come in pairs) than the already given 4 non-real zeros.  Therefore, the maximum number of non-real zeros that R(x) can have is 10.

a family is traveling due west on a road that passes a famous landmark. at a given time the bearing to the landmark is n 62° w, and after the family travels 9 miles farther the bearing is n 38° w. what is the closest the family will come to the landmark while on the road? (round your answer to two decimal places.) mi

Answers

The closest distance the family will come to the landmark while on the road is 12.03 miles.

Here, the situation represented in the question can be depicted as shown in the image below.

The family moves from F1 to F2 as the angle changes from 62 to 38.

Now, using trigonometric ratios in the smaller triangle we have-

Cot 62 = X/Y

X = Y Cot 62

Similarly, Cot 38 = (X + 9)/ Y

Substituting the value of X in the above equation we get-

Y Cot 38 = (Y Cot 62 + 9)

Y Cot 38 - Y Cot 62  = 9

Y(Cot 38 - Cot 62) = 9

Y = 9/ (Cot 38 - Cot 62)

Y = 9/ (1.2799 - 0.5317)

Y = 9/ 0.7482

Y = 12.028

Thus, the closest distance the family will come to the landmark while on the road is 12.03 miles.

Answers

The probability that the horse will not win the race is 0.7500.

The mathematical branch known as probability deals with determining the possibility of an event occurring. The conversions between probability and odds are feasible. This is because the odds are determined by dividing the likelihood that an event will occur by the likelihood that it won't.

Here, the odds of a horse winning a race are given as 2 to 6. Then, the probability of winning the horse race is calculated as,

[tex]\begin{aligned}\text{Odds}&=\frac{p}{1-p}\\\frac{2}{6}&=\frac{p}{1-p}\\2(1-p)&=6p\\2-2p&=6p\\2&=6p+2p\\8p&=2\\p&=\frac{2}{8}\\&=\frac{1}{4}\end{aligned}[/tex]

Then, the probability of not winning the horse race is,

The largest area of a rectangle that can be inscribed in a semicircle of radius 6 is 36.

What is the semicircle?

A semicircle is a one-dimensional locus of points that makes up one-half of a circle in mathematics. A semicircle's whole arc is always 180 degrees long. It just has one symmetry line.

The equation of the semicircle is

x² + y² = r²         .............(1)

The area of the rectangle is

A  = 2xy  ..................(2)

From equation (1), we get

y² = r² - x²

y = √r² - x²

Plugging this value in equation (2)

A  = 2x√r² - x²

Differentiating wrt. x using the product rule,

[tex]\frac{dA}{dx} = 2\sqrt{r^2 - x^2} - 2\frac{x^2}{\sqrt{r^2 - x^2} }[/tex]

[tex]\frac{2r^2 - 4x^2 }{\sqrt{r^2 - x^2} }[/tex]

The critical points are when

[tex]\frac{dA}{dx} = 0[/tex]

that is

[tex]\frac{2r^2 - 4x^2 }{\sqrt{r^2 - x^2} } = 0[/tex]

r² = 2x²

x = r/√2

Then,

y = √r² - x²

= √r² - (r/√2)²

= r/√2

The maximum area is

A = 2 .  r/√2 .  r/√2  = r²

A = r² = (6)² = 36

The ratio of 13 to 25 is 13/25 because 13 is a prime number

Ratio

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio denotes how two distinct entities or groups are related. For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole. For example, out of every 10 people, 5 of them like to read books. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books.

In this question, we have to find the ratio between 13 to 25

In triangle def, m∠d = (2x 19)°, m∠e = (3x 24)°, and m∠f = 87°. determine the degree measure of the exterior angle to ∠d. 54° 39° 141° 126°

Answers

The exterior angle with angle d is equivalent to 141 degrees, and the value of x is equal to 10.

Explain the term exterior angle?Whenever a side of a triangle is extended, an external angle of the triangle is created.

We must keep in mind that the total of all the angles in a triangle equals 180 degrees in order to solve this puzzle.

The given angles are-

m∠D = (2x + 19)°, m∠E = (3x + 24)°, and m∠F = 87°.

Using that formula in this case;

Thus, sum of all angles is 180°.

m < d + m < e + m < f = 180°

(2x + 19)° + (3x + 24)° + 87° = 180°

x = 10°

But if angle D is on a straight line, it is possible to find its exterior angle because angle D plus its exterior angle add up to 180 degrees.

Suppose y = external angle.

m < d + y = 180°

2x + 19 + y = 180°

And x = 10°

2(10) + 19 + y = 180°

y = 141°

Thus, the measure of the degree measure of the exterior angle is found as  141°.

Suppose you have two bank accounts. In Account A you deposit ​$200 In Account B you deposit ​$400. Account A has a simple interest rate of 3.9​%. Account B has a simple interest rate of 2.7​%. One year​ later, you get a bank statement from each bank and one of the statements shows an incorrect amount of interest. The interest for Account A is ​$7.80. The interest for Account B is ​$1,080. Which account statement is​ incorrect? Find the​ bank's likely error.

Answers

The account in which there was a mistake in the calculation of the simple interest is account B.

What is the account statement that is​ incorrect?

We know that the interest is an amount of money that is obtained on top of the initial money that was deposited. The initial money that you deposit in the account is called the principal. The rate is the percentage at which the interest is calculated and the time is the period that has elapsed since the deposit was made.

Given that;

I = PRT/100

I = interest

P = principal

R = rate

T = time

For account A

I = 200 * 3.9 * 1/100

I = $7.8

For account B;

I = 400 * 2.7 * 1/100

I = $10.8

We can see that there must have been a calculation error as the interest in account B was being calculated.

a farmer plans to enclose a rectangular pasture adjacent to a river. (see figure). the pasture must contain 80,000 square meters in order to provide enough grass for the herd. what dimensions will require the least amount of fencing if no fencing is needed along the river?

Answers

Therefore, L has a relative and absolute minimum when x = 400 m

What is Perimeter and Area ?

The area is as defined as the amount of space occupied by any shape in two dimensions. Whereas, Perimeter is the boundary or the outline of a flat shape.

Let x = length of the side parallel to the river

     y = length of each of the other two sides

Then xy = 80,000, so y = 80,000/x

Minimize:  L = length of the fence

L = x + 2y

  = x + 160,000/x, where x > 0

L' = 1 - 160,000/x2 = (x2 - 160,000)/x2

L' = 0 when x = 400 or -400

Since x can't be negative, x must be 400.

When 0 < x < 400, L' < 0.  So, L is decreasing.

When x > 400, L' > 0.  So L is increasing.

Therefore, L has a relative and absolute minimum when x = 400 m

                                                                                    y = 80,000/x = 200 m

The fence is shortest if the side parallel to the river has length 400 m and the other 2 sides each have length 200 m.
