Answer:

11.16in^2

Step-by-step explanation:

Area of a sector = theta/360 * πr²

Area of a sector = 80/360 * 3.14*4²

Area of a sector = 8/36 * 50.24

Area of a sector  = 401.92/36

Area of a sector = 11.16in^2

Hence the Area of the sector is 11.16in^2

Answer:

11.16 in²

Step-by-step explanation:

I took the test

Answer:

The object will reach its highest point 0.5 seconds after it has been thrown.

Step-by-step explanation:

The object reaches its maximum height when velocity is equal to zero, the velocity is the derivative of function height. That is:

[tex]v(t) = \frac{d}{dt}h(t)[/tex] (1)

Where [tex]v(t)[/tex] is the velocity of the object at time [tex]t[/tex], in feet per seconds.

If we know that [tex]h(t) =-16\cdot t^{2}+64\cdot t[/tex] and [tex]v(t) = 0\,\frac{ft}{s}[/tex], then the time when object reaches its highest point is:

[tex]v(t) = -32\cdot t+64[/tex]

[tex]-32\cdot t + 64 = 0[/tex]

[tex]t = 0.5\,s[/tex]

The object will reach its highest point 0.5 seconds after it has been thrown.

Im sorry for you this is too complex

Answer:

Step-by-step explanation:not right sorry

Answer:

1) There are 100 carbon-14 atoms in the wood when it died

2) A function that models the number 'N' of carbon-14 atoms present in the wood (t) years after it died is  presented as follows;

[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]

Step-by-step explanation:

The given parameters are;

The number of carbon-12 for each carbon-14 atom ≈ 10¹² carbon-12 atoms

The number of carbon-12 in the piece of wood = 10¹⁴ carbon-12 atoms

The number of carbon-14 in the piece of wood = 40 carbon-14 atoms

The number of carbon-12 in an organism = Constant

The number of carbon-14 in an organism = Decays

1) Given that the number of carbon-12 in an organism is constant, and there are 10¹² carbon-12 atoms per each carbon-14 atom, therefore, we have;

The number of carbon-12 atoms in the wood when it died = 10¹⁴ carbon-12 atoms

The number of carbon-14 atoms in the wood when it died = (10¹⁴ carbon-12 atoms)/(10¹² carbon-12 atoms/(carbon-14 atom)) = 100 carbon-14 atoms

The number of carbon-14 atoms in the wood when it died = 100 carbon-14 atoms

2) The half life of a radioactive isotope is given by the following formula;

[tex]N(t) = N_0 \cdot \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{\frac{1}{2} }} }[/tex]

The half life of carbon-14 atoms, [tex]t_{\frac{1}{2} }[/tex] ≈ 5,730 years

N₀ = The amount of carbon-14 present in the wood when it died = 100 carbon-14 atoms

Therefore, we have;

The number, N, of carbon-14 atoms present in the wood (t) years after it died is given as follows;

[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]

Answer: y + 4 = -3(x+1)

Step-by-step explanation:

We need to rewrite in form of y=mx+b.

3x+y=5

     y = -3x + 5  

The slope is -3.

In addition, the slope of two parallel line would be equal, the slope of the line would be -3.

y- y1 = m(x- x1)

y- (-4) = -3(x - -1)

y + 4 = -3(x+1)

A. The answer is 165.85.                                                                                        B. The best answer is 1.435 ·103 because while they both are really small for a rail road track that one is bigger. the final answer for that is 147.805mm.

Step-by-step explanation:

(3.9 x 10³³) / 1  =  X / (2.45 x 10⁵)  .

Solve that proportion for ' X ' in the usual way.

If you can't remember how to solve a proportion, then  

THAT's what you have to go look up.  It's much more

important to you right now than how much energy the  

sun is putting out.

7.4 x 10⁴ mm is the same size as about 243 feet !

If the tracks on a DVD were that far apart, there would not be  

room for very many tracks on a DVD.  That's not reasonable.

If the tracks are  7.4 x 10⁻⁴ mm apart, then there are about  

34,000 tracks in a stripe that's 1-inch wide.  I have no idea

how they do this, but it's certainly more reasonable than the  

other choice.                                                                                                                      Hope this helps! Can you please give me Brainleist?

Answer:

a: $49

b: $91

Explaination:

a: 35% of 140 = 49

b: 140 - 49 = 91

You're welcome! <3

The amount of discount is $49 and  the sale price of the dress is $91 and this can be determined by using the unitary method.

Given :

Elise bought a dress that was discounted 35% off of  the original price of $140.

a) The unitary method can be used in order to determine the amount of discount. If the original price is $140 then the discounted price is given by:

[tex]=\dfrac{35}{100}\times 140[/tex]

Simplify the above expression.

= $49

b) The unitary method can be used in order to determine the sale price of the dress. If the original price is $140 then the selling price is given by:

[tex]=\dfrac{65}{100}\times 140[/tex]

Simplify the above expression.

= $91

The remainder is 4

Answer:

The mistake happens in the 4th line.

Step-by-step explanation:

The first 3 lines are correct until the 4th line which is 2=6x. This is wrong. If we go back a line to the third line, it is 22=-20+6x. The part that was wrong was that they subtracted 20 from 22 to get 2. We are supposed to add 20 to each side because the -20 is negative. So the 4th line should be 42=6x. Then, we know that 6 times 7 is 42, so x is equal to 7.

22 + 53x + x = -20 + 60x

22 + 54x = -20 + 60x

22 = -20 + 6x

42 = 6x

x = 7
