Step-by-step explanation:

2.0 = 2

hope this helps ^-^

Answer:

Both will be equal as 2.0 can also be written as 2

Answer:

Technically, yes. It's called epsilon, which is defined as an infinitely small number. So

 2 + epsilon is the smallest number greater than 2. But for practical purposes no there isn't.

00

Step-by-step explanation:Not without limits. You can always move the .1 one place further from the interring. For example,  

2.1>2.01

and  

2.01>2.001

So, unless there are a limited number of decimal spaces, you can continually add an infinite amount of zeros behind the decimal point, followed by a one.

If you use two or three decimal spaces as a standard in your class, then the smallest decimal greater than 2 would be 2.01 or 2.001, respectively.

Answer: the cost of a similar scientific calculate in 2019 will be $19.01

Step-by-step explanation:

Given that;

in 1970 cost of S.C = $96.50

in 2016 cost of same calculator = $21

In 2019 cost of a similar calculator = ?

Assuming the exponential decay model applies

dN/dt = -λN

we know that λ is the decay constant

⇒ N(t) = N₀e^-λt

N(t) is price at time t year, N₀ is initial price,

so t = 0 in 1970 thus N₀ = 96.50

also t = 46 in 2016 thus N₄₆ = 21

substituting into our initial expression

N(t) = N₀e^-λt

N(46) = N₀e^-λ×46

21 = 96.50e^-46λ ⇒ In 21/96.50 = -46λ

= -1.5250 = - 46λ

λ = -1.5250 / -46

λ = 0.03315

t = 0 in 1970 thus N₀ = 96.50

also t = 49 in 2019 thus N₄₉ = ?

so

using our initial expression again

N(49) = N₀ e^-49λ

= 96.5 × e^ (-49 × 0.03315 )

= 96.5 × 0.197014404

= 19.01189 ≈ 19.01

therefore the cost of a similar scientific calculate in 2019 will be $19.01

Answer: Change it to decimal

Step-by-step explanation:

Converting it to decimal makes it easier to work with. It might make be an extra step, but in the long run of the problem it helps to make calculations accurate and easier to solve by working with simpler numbers. Converting to decimal form makes the number more precise for square roots, which are usually not whole numbers.

Answer:

x = 6, y = -2, z = 0

Step-by-step explanation:

To find x, we have to plug 0 into f(x). Therefore, x = f(0) = 2 * 0² - 8 * 0 + 6 = 6. Similarly, to find y, we have to plug 2 into f(x) so y = f(2) = 2 * 2² - 8 * 2 + 6 = -2. Finally, z = f(3) = 2 * 3² - 8 * 3 + 6 = 0.

Complete Question

A boat sails 4km on a bearing of 038 degree and then 5km on a bearing of 067 degree.(a)how far is the boat from its starting point.(b) calculate the bearing of the boat from its starting point

Answer:

a)8.717km

b) 54.146°

Step-by-step explanation:

(a)how far is the boat from its starting point.

We solve this question using resultant vectors

= (Rcos θ, Rsinθ + Rcos θ, Rsinθ)

Where

Rcos θ = x

Rsinθ = y

= (4cos38,4sin38) + (5cos67,5sin67)

= (3.152, 2.4626) + (1.9536, 4.6025)

= (5.1056, 7.065)

x = 5.1056

y = 7.065

Distance = √x² + y²

= √(5.1056²+ 7.065²)

= √75.98137636

= √8.7167296826

Approximately = 8.717 km

Therefore, the boat is 8.717km its starting point.

(b)calculate the bearing of the boat from its starting point.

The bearing of the boat is calculated using

tan θ = y/x

tan θ = 7.065/5.1056

θ = arc tan (7.065/5.1056)

= 54.145828196°

θ ≈ 54.146°

If y = 3 , then 6y = 6(3) = 18

Thank you

If the numbers are consecutive multiples of 6, and you want to call the smallest one ' n ', then the next one is (n+6) and the biggest one is (n+12).

Their sum is (3n + 18).  That's choice-C .

If you run into the same problem again, you might like to call the middle number ' n '.  Then the smallest one is (n-6) and the biggest one is (n+6),

and their sum is just 3n !  This is a lot easier to do in your head.

Answer:

y = 4/3x - 3

Step-by-step explanation:

Use the slope intercept equation, y = mx + b, where m is the slope and b is the y intercept:

Plug in the point given and the slope to find b:

y = mx + b

1 = 4/3(3) + b

1 = 4 + b

-3 = b

Then, plug this and the slope into the equation:

y = 4/3x - 3 will be the equation

Step-by-step explanation:

Given

[tex]x^5 - 2 > x[/tex]

For [tex]x < -1[/tex]

Required

Determine if the conjecture is true

[tex]x < -1[/tex] implies that the values of x are:

-2, -3, -4, -5.....

Take any value of x and substitute in [tex]x^5 - 2 > x[/tex]

Let x = -3

[tex]x^5 - 2 > x[/tex] becomes

[tex]-3^5 - 2 > -3[/tex]

[tex]-243 - 2 > -3[/tex]

[tex]-245 > -3[/tex]

The above inequality is false;

Hence:

Her conjecture is not correct

Answer:

752.95

Step-by-step explanation:

Data provided in the question

The Margin of error = 15

The confidence level is 75%, so the z value is 1.96

Now the required sample size is

[tex]= 1.96^2\times \frac{210^2}{15^2}[/tex]

= 752.95

Hence, the number of college students spends on the internet each month is 752.95

Combine like terms

6 - 4x = -2x + 8

Add 2x to both sides, and subtract 6 from both sides

-2x = 2

x = -1

[tex]\mathbf{P (X \geq 2) = 1 - P( X \leq 1) \sum \limits ^1_{x=0} ( ^{1000}_x) (0.0035)^x (0.9965)^{1000-x}}[/tex]

Step-by-step explanation:

From the information given:

The probability that at least 2 crashes occurs in the next month can be estimated by using Poisson distribution because the sample size is large and the probability of the event p = 0.0035 is rare.

∴

Let X be the random variable that follows a Poisson  distribution

The probability that at least 2 crashes occurs in the next month is:

[tex]\mathbf{P (X \geq 2) = 1 - P( X \leq 1) \sum \limits ^1_{x=0} ( ^{1000}_x) (0.0035)^x (0.9965)^{1000-x}}[/tex]

Answer:

5.1 can be written as 51/10 (the quotient of the integers 51 and 10. So it is a rational number

Step-by-step explanation:

Recall that a rational number is a number that can be written as the quotient of two integer numbers.

In particular the number 5.1 can be written as 51/10 (the quotient of the integers 51 and 10. So it is a rational number.

Problem 1

If you meant to say [tex]8^4[/tex], then you would have four copies of 8 multiplied together

[tex]8^4 = 8*8*8*8 = 4096[/tex]

==============================================

Problem 2

1/7 full = 1/3 cup of water

7*(1/7 full) = 7*(1/3 cup of water) ... multiply both sides by 7

1 full = 7/3 cup of water

So a full mug has 7/3 cups of water. Let's convert this to a mixed number

7/3 = (6+1)/3

7/3 = 6/3 + 1/3

7/3 = 2 + (1/3)

7/3 = 2 & 1/3

The full capacity of the cup is 7/3 cups or 2 & 1/3 cups

7/3 is the improper fraction form

2 & 1/3 is the mixed number form

One way to think of it is to imagine there are 7 cookies and you want to distribute among 3 friends. We could say 7/3 = 2 remainder 1 meaning each person gets 2 full cookies and there's 1 left over. So that's how we'd get 2 & 1/3.

Answer:

a

   No singular point due to the exponent in the solution

    The interval is   [tex]-\infty  <0 <  \infty[/tex]

b

   NONE

Step-by-step explanation:

From the question we are told that

     [tex]\frac{dy}{dx} =  9y[/tex]

The generally solution is mathematically represented as

         [tex]\frac{dy }{dx}  =  9y[/tex]

=>       [tex]\frac{dy}{y}  =  9dx[/tex]

integrating both sides  

         [tex]\int\limits  {\frac{ dy}{y} } \,  = \int\limits  {9} \, dx[/tex]

  =>   [tex]lny = 9x + c[/tex]

 =>   [tex]y =  e^{9x +c }[/tex]

 =>    [tex]y =  e^{9x} e^{c}[/tex]

Here [tex]e^c  =  C[/tex]

=>     [tex]y = C  e^{9x}[/tex]

From the above equation we see that the domain for x has no singular point the interval is

       [tex]-\infty  <0 <  \infty[/tex]

Also there is no transient term in the general solution obtained because as  [tex]x \to \infty[/tex] there no case where [tex]y \to 0[/tex]

Answer:

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{3}[/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 )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = ((- 2, 3) and (x₂, y₂ ) = (4, 1)

m = [tex]\frac{1-3}{4+2}[/tex] = [tex]\frac{-2}{6}[/tex] = - [tex]\frac{1}{3}[/tex] , thus

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 3), then

3 = [tex]\frac{2}{3}[/tex] + c ⇒ c = 3 - [tex]\frac{2}{3}[/tex] = [tex]\frac{7}{3}[/tex]

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{3}[/tex] ← equation of line
