A circle has a radius of 5.4 m. what is the exact length of an arc formed by a central angle measuring 60°? enter your answer in the box. express your answer using π .

Answers

Answer 1

Assuming the radius is 5.4m. The exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.

Length of an arc

Arc length of the circle=(theta)/360×pi×diameter

Diameter=2×radius

Where:

radius=5.4

Diameter=2×5.4=10.8

theta=60°

Arc length:

Arc length=60°/360°×π×10.8

Arc length=5.6548667765 or 1.8π

Inconclusion the exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.

Among all pairs of numbers whose difference is 14 find a pair whose product is as small as possible

Answers

The pair two numbers whose difference is 14 and the product is as small as possible (i.e. -49) are (-7,7)

What are word problems?

In mathematical concepts, word problems involve a crucial understanding of the problem and knowing which mathematical method and arithmetic operations are best suited to solving the problem.

If we assume that the smaller number should be = a and the larger number = a + 14.

Thus, their product (X) can be expressed as:

= a(a+14)

= a² + 14a

The smallest possible value implies the minimum value, i.e.

[tex]\mathbf{\dfrac{dX}{da} = 2a + 14}[/tex]

Thus,

2a + 14 = 0

a = - 14/2

a = -7

Therefore, we can conclude that the pair of two numbers whose difference is 14 and the product is as small as possible (i.e. -49) is (-7,7).

A driver of a 1 000 kg jeepney travelling at a speed of 16,7 m/s bound for divisoria applies the car's brakes when he sees a red light along recto avenue. the car's brakes provide a frictional force of 8 000 n. determine the stopping distance of the car.

Answers

The stopping Distance of the Car with the given parameters is; 17.43 m

What is the stopping sight distance?

We are given;

mass; m = 1 000 kg

speed; u = 16.7 m/s

Frictional force; F = 8000 N

distance, s  = ?

final velocity = 0 m/s (car stops)

Formula for final velocity is;

v² = u² + 2as

but a = negative (deceleration)

And F = ma

Thus;

a = F/m = 8000/1000

a = 8 m/s²

Thus;

0 = (16.7)² - 2(8)(s)

278.89 = 16s

s  = 17.43 m

Stopping distance = 17.43 m

Suppose that the rabbit population on mr. jenkins' farm follows the formula

Answers

Jenkins' farm tracks the procedure p(t)=3000tt+1. where t≥0 is the period (in months) since the start of the year.

As time (t) increases, the rabbit population (p(t)) will also increase, but it will approach a maximum value without ever actually reaching it, resulting in continuous growth that slows down over time.

We have,

Given formula: p(t) = 300t / (t + 1)

As time (t) increases, the denominator (t + 1) also increases.

The rabbit population (p(t)) is calculated by dividing 300t by (t + 1).

Now, let's examine the behaviour as t becomes larger:

When t is very small (close to 0), the population p(t) is also small, since the denominator (t + 1) is close to 1.

As t increases, the denominator (t + 1) grows, causing the value of p(t) to increase.

However, the rate of increase slows down as t gets larger.

This is because the denominator grows faster than the numerator (300t).

Eventually, as t becomes very large, the value of p(t) approaches but never quite reaches a maximum value.

This behaviour is characteristic of a rational function where the numerator's growth is outpaced by the denominator's growth, resulting in an asymptotic approach to a certain value.

Thus,

As time (t) increases, the rabbit population (p(t)) will also increase, but it will approach a maximum value without ever actually reaching it, resulting in continuous growth that slows down over time.

Of the 10,000 clocks from which the sample was chosen, about how many clocks are probably not defective?

Answers

The number of clocks that are not defective is an illustration of proportions

Of the 10000 clocks, 9250 are probably not defective

How to determine the number of clocks that are not defective?

From the complete question, we have the following parameter:

15 out of 200 clocks are defective

The above means that the number of clocks that are not defective is:

Not defective = 200 - 15

Not defective = 185

Express as percentage

Not defective = 185/200

Not defective = 92.5%

In 10,000 the number of clocks that are not defective would be:

Not defective = 92.5% * 10000

Not defective = 9250

Hence, 9250 of the 10000 clocks are probably not defective
