two cars start moving from the same point. one travels south at 60 miles per hour. the other car travels west at 25 miles per hour. at what rate is the distance between the cars increasing 2 hours later?

Answers

Answer 1

The distance between the cars increasing 2 hours later is 65mph

Let’s say, the velocity in the west is x, the velocity in the south is y, and the distance between them is s at any time t. Since the west and south directions are perpendicular to each other, this will be for a right-angled triangle.

So, we have [tex]x^2 + y^2 = s^2[/tex] --------------(1)  

(please note all of them are changing as t increases.)

So, x=u×t and y=v×t,

so using (1), we can write

[tex][(u\times t)^2 + (v\times t)^2] = s^2[/tex]

[tex]s= \sqrt{(u^2 + v^2)}* t[/tex]

Using the value of u and v,

get [tex]\sqrt{(u^2 + v^2)}[/tex]= 65

So, s= 65 t

ds/dt = 65 mph

There fore the distance between the cars increasing 2 hours later is 65mph

what fraction shows the number of hours saide's dog sleeps every 4 hours in a day? Complete the fraction.

Answers

The fraction that shows the number of hours Saide's dog sleeps every 4 hours in a day is 1/6.

How to calculate the fraction?

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.

It should be noted that there are 24 hours in day. Since the dog sleeps for 4 hours in a day, the fraction will be:

= Number of hours slept / Total hours

= 4 / 24.

What are the lengths of the major and minor axes of the ellipse?

(x−3)227+(y+4)245=1

Answers

The lengths of the major and minor axis are 4√6 and 4√3.

What is Major and Minor Axis?

A point on a curve is described by an ellipse if its location is such that the sum of the distances between its two focal points is a constant.

(x−h)²/ b² +(y- k)² /a² = 1

Given:

(x−3)²/ 27+(y+4)² /45=1

The above equation can be compared to the standard equation of an ellipse

(x−h)²/ b² +(y- k)² /a² = 1

where, (h, k) = coordinates of the center of the ellipse

a =  length of the semi major axis

b = length of the semi minor axis

By comparison, we have;

(h, k) = (3, -4)

a = √(24) = 2 x√6

b = √(12) = 2 x√3

and, length of the major axis = 2a

length of the minor axis = 2b

Thus, The length of the major axis is

2x a = 2 × 2 x √6 = 4√6

and, length of the minor axis is

2•b = 2 × 2√3 = 4√3

show that the convergence of a series is not affected by changing a finite number of its terms. (of course, the value of the sum may be changed.)

Answers

Convergent Series:

A Convergent Series is a series whose partial sums tend to a specific member is called a limit.

  ∑ 1/2n = 1/2+ 1/4 + 1/8 + 1/16 +........

Given an infinite series ∑₁ ∞ an determine the series is convergence. Recall that we can actually do better with geometric series not only we can determine convergence but also divergence. We can also calculate geometric series.

Suppose we are given a series ∑ aₙ which is not quite a geometric series but becomes a geometric series for sufficiently large n. That is we can find an integer N such that aₙ = aₓⁿ for all n > N. we don't have a general formula for aₙ when n ≤ N. The values of aₙ for small n don't effect Sₙ is convergence or not.

As a moment of fact, we never used the fact that aₙ eventually become geometric. More general ∑aₙ is convergent series, we can add a finite number of terms to the be gaining of this series or remove a finite number of terms from the be gaining of the series without affecting the convergence  of the series. For Example: if ∑aₙ convergence then so does

                        10 + 10¹⁰ + 10 ¹⁰⁰ + 10¹⁰⁰⁰ + ∑aₙ

Similarly, if ∑aₙ convergence then,

                a₁₀₀₀ +a₁₀₀₁ +a₁₀₀₂ + ..... = ∑₁₀₀₀ ∞ aₙ

However, the fact that we are only adding finitely many terms to the series is essential. That is, when it comes to determining convergence of a series ∑aₙ , we can see that only the asymptotic  behavior of ∑aₙ matter, that is, only the behavior of the sequence aₙ as n--- ∞ affects convergence.

An element with a mass of 400 grams decays by 29.8% per minute. To the nearest
minute, how long will it be until there are 2 grams of the element remaining?

Answers

The time elapsed, to the nearest minute, until only 2 grams of the element remains is 15 minutes.

We have an element. The element has a mass of 400 grams. The element decays by 29.8% per minute. We need to find the time duration after which there will be only 2 grams of the element remaining. Let the initial mass of the element, the final mass of the element, the rate of decay, and the time elapsed be represented by the variables m, M, r, and t. We can write the equation as given below.

M = m(1 - r)^t

2 = 400(1 - 0.298)^t

0.005 = (0.702)^t

log(0.005) = t*log(0.702)

t = log(0.005)/log(0.702)

t = 14.97

The time taken, to the nearest minute, is 15 minutes.

Calculate the price per 72 rolls for each shop.
Write which shop is the best value for money in the comment box.

Answers

The price of 72 rolls of toilet rolls in each shop is:

Lidal - $25.20Oldi - $25.92

The shop with the best value for money is Lidal.

How to find the price?

Lidal sells 8 toilet rolls for $2.80 and so if it was to sell 72 rolls, it would sell at a price of:

= Price per 8 rolls x Number of rolls / Number of rolls in packages

= 2.80 x 72 / 8

= 2. 80 x 9

= $25.20

Oldi sells 9 toilet rolls for $3.24 so the cost of 72 rolls would be:

= 3. 24 x 72 / 9

= 3. 24 x 8

= $25. 92

The shop with the best value for money is the cheaper one which is Lidal.

What is distance?

In Science, distance can be defined as the amount of ground that is covered (travelled) by a physical object over a particular period of time and speed, irrespective of its direction, starting point or ending point.

Mathematically, the distance traveled by a physical object (body) can be calculated by using this formula:

Distance = speed (rate) × time

Note: Let the variable x represent the halfway distance.

Since it takes the same amount of time to walk each block and halfway there, half of the berries are gone. Therefore, we have the following:

At point x, the number of strawberries that is left is equal to 12 strawberries while the distance after walking 3 more blocks, you still have 5 blocks to go would be given by:

1/2 × x = (3 + 5) = 8

1/2 × x = 8

Distance, x = 8 × 2

Distance, x = 16 blocks.

Now, we can determine the rate at which this person walks a block:

Rate (speed) = 28/16

Step 2: Determine their coordinates.

Step 3: Add the x coordinates of both ends and divide by 2.

Step 4: Adding the y coordinates of both endpoints, divide by 2, and complete the step.

Now the value of x will be,

→ 2x + 3 = -3x + 3

→ 2x + 3x = 3 - 3

→ 5x = 0

→ x = 0/5

→ [ x = 0 ]

Then the value of y will be,

→ y = -3x + 3

→ y = -3(0) + 3

→ y = 0 + 3

→ [ y = 3 ]

Hence, the value of y is 3.
